A client is prescribed lorazepam (Ativan) 0.5 mg qid and 1 mg PRN q8h. The maximum daily dose of lorazepam should not exceed 4 mg QD. This client would be able to receive ______ PRN doses as the maximum number of PRN lorazepam doses.
This client should receive 2 PRN doses. The test taker must recognize that medications are given three times in a 24-hour period when the order reads q8h: 1 mg x 3 = 3 mg. The test taker must factor in the 0.5 mg qid = 2 mg. These two dosages together add up to 5 mg, 1 mg above the maximum daily dose of lorazepam (Ativan). The client would be able to receive only two of the three PRN doses of lorazepam. TEST-TAKING HINT: To answer this question correctly, the test taker must recognize that the timing of standing medication may affect the decision-making process related to administration of PRN medications. In this case, although the PRN medication is ordered q8h, and could be given three times, the standing medication dosage limits the PRN to two doses, each at least 8 hours apart.

The client's serum sodium value is 152 mEq/L. Which of the following nursing interventions is most appropriate for this client? (Select all that apply.) 1. Assess for inadequate water intake or diarrhea. 2. Administer a 0.45% NaCl IV solution. 3. Hold all doses of glucocorticoids. 4. Notify the health care provider. 5. Have the client drink as much water as possible.
1 and 4 Rationale: Hypernatremia is defined as serum sodium levels higher than 148 mEq/L. Elevated levels may be associated with inadequate fluid intake, diarrhea, fever, or after burns when fluid is lost from the burn site. Because this laboratory value is significantly increased, the health care provider should be notified.
A nurse enters a patient's room who has a suspected diagnosis of spinal muscular atrophy (SMA). Which finding by the nurse is most concerning? 1) The child's chest is visibly sunken inward. 2) The child appears to have an S-shaped sign. 3) The child has absent tendon reflexes. 4) The child has trouble initiating spontaneous movement.
1) Pectus excavatum can occur when the child breathes using the diaphragm without intercostal muscle support (paradoxical breathing). This causes the chest to funnel and the xiphoid process retracts, which further restricts respiratory development. Scoliosis, absent or diminished tendon reflexes, and diminished ability to initiate spontaneous movement are all expected in this patient. Page 816.
The nurse is caring for a child diagnosed with pectus excavatum post-op day 1 from a steel bar placement. Which finding by the nurse is most concerning? 1) Breath sounds are absent on the right side 2) The child is crying and says his chest hurts 3) The child is lying supine. 4) The child's mother is asking the child to roll to his right side and finish his homework.
1) This indicates a pneumothorax may have occurred as a post-operative complication, and this needs to be addressed immediately. The child should not roll to EITHER side for 4 weeks after surgery. However, we can encourage aerobic activity. Pain is expected after surgery.
A client with cancer is secreting excessive amounts of antidiuretic hormone. The nurse will monitor the client for which consequence of excess antidiuretic hormone secretion? 1. Fluid volume excess 2. Hyperkalemia 3. Hypernatremia 4. Dehydration
1. Antidiuretic hormone increases renal tubular permeability and water retention.
A client uses a metered-dose inhaler (MDI) to aid in management of his asthma. Which action by the client indicates to the nurse that he needs further instruction regarding its use? Select all that apply. 1. Activation of the MDI is not coordinated with inspiration. 2. The client inspires rapidly when using the MDI. 3. The client holds his breath for 3 seconds after inhaling with the MDI. 4. The client shakes the MDI after use. 5. The client performs puffs in rapid succession.
1, 2, 3, 4, 5. Utilization of an MDI requires coordination between activation and inspiration; deep breaths to ensure that medication is distributed into the lungs, holding the breath for 10 seconds or as long as possible to disperse the medication into the lungs, shaking up the medication in the MDI before use, and a sufficient amount of time between puffs to provide an adequate amount of inhalation medication.
Which of the following findings would most likely indicate the presence of a respiratory infection in a client with asthma? 1. Cough productive of yellow sputum. 2. Bilateral expiratory wheezing. 3. Chest tightness. 4. Respiratory rate of 30 breaths/ minute.
1. A cough productive of yellow sputum is the most likely indicator of a respiratory infection. The other signs and symptoms- wheezing, chest tightness, and increased respiratory rate- are all findings associated with an asthma attack and do not necessarily mean an infection is present.
The nurse has provided teaching to a family regarding clean intermittent catheterization for their 4 year-old daughter with myelomeningocele. Which statement, if made by the family, indicates that further teaching is required by the nurse? Select all that apply: 1) "When the catheter becomes stiff, we will soak it in warm water to soften it." 2) "We will store our catheter in a zip-top plastic bag." 3) "We will insert the catheter about 4-6 inches, or until we see urine flow." 4) "We will lubricate the catheter with a petroleum-based jelly before usage." 5) "We will clean our daughter's genitalia with a washcloth before catheterization."
1, 3, 4 When catheters become stiff, cloudy, rough, cracked, or damaged in general, they need to be thrown away. Catheters should be inserted approximately 2-3 inches for females and 4-6 inches for males, or until urine flow is noted. A water-based lubricator needs to be used. See page 809.
Which of the following is significant data to gather from a client who has been diagnosed with pneumonia? Select all that apply. 1. Quality of breath sounds. 2. Presence of bowel sounds. 3. Occurence of chest pain. 4. Amount of peripheral edema. 5. Color of nail beds.
1, 3, 5. A respiratory assessment, which includes auscultating breath sounds and assessing the color of the nail beds, is a priority for clients with pneumonia. Assessing for the presence of chest pain is also an important respiratory assessment as chest pain can interfere with the client's ability to breathe deeply. Auscultating bowel sounds and assessing for peripheral edema may be appropriate assessments, but these are not priority assessments for the client with pneumonia.
The nurse administers two 325 mg aspirin every 4 hours to a client with pneumonia. The nurse should evaluate the outcome of administering the drug by assessing which of the following? Select all that apply. 1. Decreased pain when breathing. 2. Prolonged clotting time. 3. Decreased temperature. 4. Decreased respiratory rate. 5. Increased ability to expectorate secretions.
1, 3. Aspirin is administered to clients with pneumonia because it is an analgesic that helps control chest discomfort and an antipyretic that helps reduce fever. Aspirin has an anticoagulant effect, but that is not the reason for prescribing it for a client with pneumonia, and the use of the drug will be short term. Aspirin does not affect the respiratory rate, and does not facilitate expectoration of secretions.
The nurse is teaching the client how to use a metered-dose inhaler (MDI) to administer a corticosteroid. Which of the following client actions indicates that he is using the MDI correctly? Select all that apply. 1. The inhaler is held upright. 2. The head is tilted down while inhaling the medicine. 3. The client waits 5 minutes between puffs. 4. The mouth is rinsed with water following administration. 5. The client lies supine for 15 minutes following administration.
1, 4. The client should shake the inhaler and hold it upright when administering the drug. The head should be tilted back slightly. The client should wait about 1 to 2 minutes between puffs. The mouth should be rinsed following the use of a corticosteroid MDI to decrease the likelihood of developing an oral infection. The client does not need to lie supine; instead, the client will likely to be able to breathe more freely if sitting upright.
The nurse is caring for a client who is experiencing acute renal failure. The nurse knows that this client may experience problems regulating: Select all that apply. 1. Fluid balance. 2. Electrolyte composition. 3. The pH of body fluids. 4. Heart rate. 5. Blood pressure.
1,2,3,5. The kidneys are the primary organs for regulating fluid balance through filtration and urine output.. The kidneys are the primary organs for regulating electrolyte composition through filtration and urine output. The kidneys are the primary organ for regulating the pH of body fluids through filtration and urine output. The kidneys play a role in regulating blood pressure through the secretion of renin.
Which substances enter the filtrate by active secretion? Select all that apply. 1. Hydrogen 2. Potassium 3. Phosphate 4. Chloride 5. Sodium
1,2,3. Hydrogen is pumped into filtrate by molecular pumps. Potassium is pumped into filtrate by molecular pumps. Phosphate is pumped into filtrate by molecular pumps.
A home care nurse is instructing a client with congestive heart failure on daily self-monitoring between home care visits. The nurse should instruct the client to monitor and record: Select all that apply. 1. Weight. 2. Pulse. 3. Temperature. 4. Blood pressure. 5. Respiratory rate.
1,2,4. It is essential that the client measure and record weight daily to monitor for fluid loss or retention. It is essential that the client measure and record the pulse daily to determine the effectiveness of the medication therapy. It is essential that the client measure and record daily BP to determine the effectiveness of the medication therapy.
The nurse is caring for a client admitted to the med-surg unit with hypervolemia that has resulted from renal failure. The nurse anticipates that medications that may be ordered to treat this condition would include: Select all that apply. 1. Furosemide (Lasix). 2. Hydrochlorothiazide (Microzide). 3. Epoetin alfa (Procrit). 4. Polystyrene sulfate (Kayexalate). 5. Sodium bicarbonate.
1,2. Loop diuretics are often given to treat the hypervolemia that accompanies renal failure. Thiazide diuretics are often given to treat the hypervolemia that accompanies renal failure.
The nurse is preparing to discharge a client who has been placed on a loop diuretic for the treatment of congestive heart failure. Which foods should the nurse encourage the client to consume to prevent serious adverse effects associated with the medication? Select all that apply. 1. Bananas 2. Red meat 3. Oranges 4. Dried dates 5. Green leafy vegetables
1,3,4. Bananas are a potassium-rich food. Clients on loop diuretics should eat foods rich in potassium. Citrus fruits are a good source of potassium. Clients on loop diuretics should eat foods rich in potassium. Dried dates are a good source of potassium. Clients on loop diuretics should eat foods rich in potassium.
A client has been diagnosed with chronic renal failure and is receiving hydrochlorothiazide (HCTZ). The nurse has taught the client about the importance of kidney function and evaluates that learning has occurred when the client makes which statements? Select all that apply. 1. "The kidneys help my heart by balancing potassium." 2. "The kidneys help decrease infections by excreting bacteria." 3. "The kidneys keep blood pressure from getting too low." 4. "The kidneys balance the fluid and electrolytes in my body." 5. "The kidneys help regulate the oxygen levels in my blood."
1,3,4. The kidneys are the primary organs for regulating potassium balance. The kidneys secrete renin, which helps to maintain blood pressure. The kidneys are the primary organs for regulating fluid and electrolyte balance.
A client is prescribed metaproterenol (Alupent) via a metered-dose inhaler, two puffs every 4 hours. The nurse instructs the client to report adverse effects. Which of the following are potential adverse effects of metaproterenol? 1. Irregular heartbeat. 2. Constipation. 3. Pedal edema. 4. Decreased pulse rate.
1. Irregular heartbeats should be reported promptly to the care provider. Metaproterenol (Alupent) may cause irregular heartbeat, tachycardia, or anginal pain because of its adrenergic effect on beta-adrenergic receptors in the heart. It is not recommended for use in clients with known cardiac disorders. Metaproterenol does not cause constipation, pedal edema, or bradycardia.
When developing a discharge plan to manage the care of a client with chronic obstructive pulmonary disease (COPD), the nurse should advise the the client to expect to: 1. Develop respiratory infections easily. 2. Maintain current status. 3. Require less supplemental oxygen. 4. Show permanent improvement.
1. A client with COPD is at high risk for development of respiratory infections. COPD is slowly progressive; therefore, maintaining current status and establishing a goal that the client will require less supplemental oxygen are unrealistic expectations. Treatment may slow progression of the disease, but permanent improvement is highly unlikely.
Which of the following is a priority goal for the client with chronic obstructive pulmonary disease (COPD)? 1. Maintaining functional ability. 2. Minimizing chest pain. 3. Increasing carbon dioxide levels in the blood. 4. Treating infectious agents.
1. A priority goal for the client with COPD is to manage the signs and symptoms of the disease process so as to maintain the client's functional ability. Chest pain is not a typical symptom of COPD. The carbon dioxide concentration in the blood is increased to an abnormal level in clients with COPD; it would not be a goal to increase the level further. Preventing infection would be a goal of care for the client with COPD.
The client with pneumonia develops mild constipation, and the nurse administers docusate sodium (Colace) as ordered. This drug works by: 1. Softening the stool. 2. Lubricating the stool. 3. Increasing stool bulk. 4. Stimulating peristalsis.
1. Docusate sodium (Colace) is a stool softener that allows fluid and fatty substances to enter the stool and soften it. Docusate sodium does not lubricate the stool, increase stool bulk, or stimulate peristalsis.
A client with deep vein thrombosis suddenly develops dyspnea, tachypnea, and chest discomfort. What should the nurse do first? 1. Elevate the head of the bed 30 to 45 degrees. 2. Encourage the client to cough and deep breathe. 3. Auscultate the lungs to detect abnormal breath sounds. 4. Contact the physician.
1. Elevating the head of the bed facilitates breathing because the lungs are able to expand as the diaphragm descends. Coughing and deep breathing do not alleviate the symptoms of a pulmonary embolus, nor does lung auscultation. The physician must be kept informed of changes in a client's status, but the priority in this case is alleviating the symptoms.
Bed rest is prescribed for a client with pneumonia during the acute phase of the illness. The nurse should determine the effectiveness of bed rest by assessing the client's: 1. Decreased cellular demand for oxygen. 2. Reduced episodes of coughing. 3. Diminished pain when breathing deeply. 4. Ability to expectorate secretions more easily.
1. Exudate in the alveoli interferes with ventilation and the diffusion of gases in clients with pneumonia. During the acute phase of the illness, it is essential to reduce the body's need for oxygen at the cellular level; bed rest is the most effective method for doing so. Bed rest does not decrease coughing or promote clearance of secretions, and it does not reduce pain when taking deep breaths.
Which of the following physical assessment findings are normal for a client with advanced chronic obstructive pulmonary disease (COPD)? 1. Increased anteroposterior chest diameter. 2. Underdeveloped neck muscles. 3. Collapsed neck veins. 4. Increased chest excursions with respiration.
1. Increased anteroposterior chest diameter is characteristic of advanced COPD. Air is trapped in the overextended alveoli, and the ribs are fixed in an inspiratory position. The result is the typical barrel-chested appearance. Overly developed, not underdeveloped, neck muscles are associated with COPD because of their increased use in the work of breathing. Distended, not collapsed, neck veins are associated with COPD as a symptom of the heart failure that the client may experience secondary to the increased workload on the heart to pump blood into the pulmonary vasculature. Diminished, not increased, chest excursion is associated with COPD.
Which of the following health promotion activities should the nurse include in the discharge teaching plan for a client with asthma? 1. Incorporate physical exercise as tolerated into the daily routine. 2. Monitor peak flow numbers after meals and at bedtime. 3. Eliminate stressors in the work and home environment. 4. Use sedatives to ensure uninterrupted sleep at night.
1. Physical exercise is beneficial and should be incorporated as tolerated into the client's schedule. Peak flow numbers should be monitored daily, usually in the morning (before taking medication). Peak flow does not need to be monitored after each meal. Stressors in the client's life should be modified but cannot be totally eliminated. Although adequate sleep is important, it is not recommended that sedatives be routinely taken to induce sleep.
A client experiencing a severe asthma attack has the following arterial blood gas: pH 7.33; Pco2 48; Po2 58; HCO3 26. Which of the following orders should the nurse perform first? 1. Albuterol (Proventil) nebulizer. 2. Chest x-ray. 3. Ipratropium (Atrovent) inhaler. 4. Sputum culture.
1. The arterial blood gas reveals a respiratory acidosis with hypoxia. A quick-acting bronchodilator, albuterol, should be administered via nebulizer to improve gas exchange. Ipratropium is a maintenance treatment for bronchospasm that can be used with albuterol. A chest x-ray and sputum sample can be obtained once the client is stable.
A 79-year-old female client is admitted to the hospital with a diagnosis of bacterial pneumonia. While obtaining the client's health history, the nurse learns that the client has osteoarthritis, follows a vegetarian diet, and is very concerned with cleanliness. Which of the following would most likely be a predisposing factor for the diagnosis of pneumonia? 1. Age. 2. Osteoarthritis. 3. Vegetarian diet. 4. Daily bathing.
1. The client's age is a predisposing factor for pneumonia; pneumonia is more common in elderly or debilitated clients. Other predisposing factors include smoking, upper respiratory tract infections, malnutrition, immunosuppression, and the presence of a chronic illness. Osteoarthritis, a nutritionally sound vegetarian diet, and frequent bathing are not predisposing factors for pneumonia.
The nurse is planning to teach a client with chronic obstructive pulmonary disease how to cough effectively. Which of the following instructions should be included? 1. Take a deep abdominal breath, bend forward, and cough three or four times on exhalation. 2. Lie flat on the back, splint the thorax, take two deep breaths, and cough. 3. Take several rapid, shallow breaths and then cough forcefully. 4. Assume a side-lying position, extend the arm over the head, and alternate deep breathing with coughing.
1. The goal of effective coughing is to conserve energy, facilitate removal of secretions, and minimize airway collapse. The client should assume a sitting position with feet on the floor if possible. The client should bend forward slightly and, using pursed-lip breathing, exhale. After resuming an upright position, the client should use abdominal breathing to slowly and deeply inhale. After repeating this process three or four times, the client should take a deep abdominal breath, bend forward, and cough three or four times upon exhalation (" huff" cough). Lying flat does not enhance lung expansion; sitting upright promotes full expansion of the thorax. Shallow breathing does not facilitate removal of secretions, and forceful coughing promotes collapse of airways. A side-lying position does not allow for adequate chest expansion to promote deep breathing.
The nurse is caring for a Vietnam War veteran with a history of explosive anger, unemployment, and depression since being discharged from the service. The client reports feeling ashamed of being "weak" and of letting past experiences control thoughts and actions in the present. What is the nurse's best response?
1. "Many people who have been in your situation experience similar emotions and behaviors."
A client with a history of drug and alcohol abuse is concerned that the hospital will divulge her history to her employer without her knowledge. What response by the nurse would be appropriate?
1. "Your personal health information can't be disclosed to your employer without your permission."

1. 2nd most common 2. used for sub-partial, complete-partial, tonic/clonic
Which of the following symptom assessments would validate the diagnosis of generalized anxiety disorder? Select all that apply. 1. Excessive worry about items difficult to control. 2. Muscle tension. 3. Hypersomnia. 4. Excessive amounts of energy. 5. Feeling "keyed up" or "on edge."
1. A client diagnosed with generalized anxiety disorder (GAD) would experience excessive worry about items difficult to control. 2. A client diagnosed with GAD would experience muscle tension. 5. A client diagnosed with GAD would experience an increased startle reflex and tension, causing feelings of being "keyed up" or being "on edge." TEST-TAKING HINT: To answer this question correctly, the test taker would need to recognize the signs and symptoms of GAD.
Which of the following would the nurse expect to assess in a client diagnosed with posttraumatic stress disorder? Select all that apply. 1. Dissociative events. 2. Intense fear and helplessness. 3. Excessive attachment and dependence toward others. 4. Full range of affect. 5. Avoidance of activities that are associated with the trauma.
1. A client diagnosed with posttraumatic stress disorder (PTSD) may have dissociative events in which the client feels detached from the situation or feelings. 2. A client diagnosed with PTSD may have intense fear and feelings of helplessness. 5. A client diagnosed with PTSD avoids activities associated with the traumatic event. TEST-TAKING HINT: To answer this question correctly, the test taker must be aware of the different symptoms associated with the diagnosis of PTSD.
A client leaving home for the first time in a year arrives on the psychiatric in-patient unit wearing a surgical mask and white gloves and crying, "The germs in here are going to kill me." Which nursing diagnosis addresses this client's problem? 1. Social isolation R /T fear of germs AEB continually refusing to leave the home. 2. Fear of germs R /T obsessive-compulsive disorder, resulting in dysfunctional isolation. 3. Ineffective coping AEB dysfunctional isolation R /T unrealistic fear of germs. 4. Anxiety R /T the inability to leave home, resulting in dysfunctional fear of germs.
1. According to the North American Nursing Diagnosis Association (NANDA), the nursing diagnosis format must contain three essential components: (1) identification of the health problem, (2) presentation of the etiology (or cause) of the problem, and (3) description of a cluster of signs and symptoms known as "defining characteristics." The correct answer, "1," contains all three components in the correct order: health problem/NANDA stem (social isolation); etiology/cause, or R /T (fear of germs); and signs and symptoms, or AEB (refusing to leave home for the past year). Because this client has been unable to leave home for a year as a result of fear of germs, the client's behaviors meet the defining characteristics of social isolation. TEST-TAKING HINT: To answer this question correctly, the test taker needs to know the components of a correctly stated nursing diagnosis and the order in which these components are written.
The nurse is caring for four pts on a renal failure unit and recognizes which drug as safe to administer to a client with hypokalemia? 1. Amiloride (Midamor) 2. Chlorothiazide (Diuril) 3. Bumetanide (Bumex) 4. Ethacrynic acid (Edecrin)
1. Amiloride is a potassium-sparing diuretic.
47. The nurse asks the male client with epilepsy if he has auras with his seizures. The client says, "I don't know what you mean. What are auras?" Which statement by the nurse would be the best response? 1. "Some people have a warning that the seizure is about to start." 2. "Auras occur when you are physically and psychologically exhausted." 3. "You're concerned that you do not have auras before your seizures?" 4. "Auras usually cause you to be sleepy after you have a seizure."
1. An aura is a visual, auditory, or olfactory occurrence that takes place prior to a seizure and warns the client a seizure is about to occur. The aura often allows time for the client to lie down on the floor or find a safe place to have the seizure.
A client newly admitted to an in-patient psychiatric unit is diagnosed with obsessivecompulsive disorder. Which correctly stated nursing diagnosis takes priority? 1. Anxiety R /T obsessive thoughts AEB ritualistic behaviors. 2. Powerlessness R /T ritualistic behaviors AEB statements of lack of control. 3. Fear R /T a traumatic event AEB stimulus avoidance. 4. Social isolation R /T increased levels of anxiety AEB not attending groups.
1. Anxiety is the underlying cause of the diagnosis of obsessive compulsive disorder (OCD), therefore, anxiety R/T obsessive thoughts is the priority nursing diagnosis for the client newly admitted for the treatment of this disorder. TEST-TAKING HINT: When the question is asking for a priority, the test taker should consider which client problem would need to be addressed before any other problem can be explored. When anxiety is decreased, social isolation should improve, and feelings about powerlessness can be expressed.
During a panic attack, a client runs to the nurse and reports breathing difficulty, chest pain, and palpitations. The client is pale with his mouth wide open and eyebrows raised. What should the nurse do first?
1. Assist the client to breathe deeply into a paper bag
During alprazolam (Xanax) therapy, the nurse should be alert for which dose-related adverse reaction?
1. Ataxia
Because antianxiety agents such as lorazepam (Ativan) can potentiate the effects of other drugs, the nurse should incorporate which instruction in her teaching plan?
1. Avoid mixing antianxiety agents with alcohol or other central nervous system (CNS) depressants

Anxiety is a symptom that can result from which of the following physiological conditions? Select all that apply. 1. Chronic obstructive pulmonary disease. 2. Hyperthyroidism. 3. Hypertension. 4. Diverticulosis. 5. Hypoglycemia.
1. Chronic obstructive pulmonary disease causes shortness of breath. Air deprivation causes anxiety, sometimes to the point of panic. 2. Hyperthyroidism (Graves's disease) involves excess stimulation of the sympathetic nervous system and excessive levels of thyroxine. Anxiety is one of several symptoms brought on by these increases. 5. Marked irritability and anxiety are some of the many symptoms associated with hypoglycemia. TEST-TAKING HINT: To answer this question correctly, the test taker needs to understand that anxiety is manifested by physiological responses.
Which of the following medications can be used to treat clients with anxiety disorders? Select all that apply. 1. Clonidine hydrochloride (Catapres). 2. Fluvoxamine maleate (Luvox). 3. Buspirone (BuSpar). 4. Alprazolam (Xanax). 5. Haloperidol (Haldol).
1. Clonidine hydrochloride (Catapres) is used in the treatment of panic disorders and generalized anxiety disorder. 2. Fluvoxamine maleate (Luvox) is used in the treatment of obsessive-compulsive disorder. 3. Buspirone (BuSpar) is used in the treatment of panic disorders and generalized anxiety disorders. 4. Alprazolam (Xanax), a benzodiazepine, is used for the short-term treatment of anxiety disorders. TEST-TAKING HINT: To answer this question correctly, the test taker needs to understand that many medications are used off-label to treat anxiety disorders.
The nurse caring for a client with renal failure will question the use of a usual dose of: 1. Digoxin (Lanoxin). 2. Cholestyramine (Questran). 3. Fluvastatin (Lescol). 4. Benzylpenicillin (penicillin G)
1. Digoxin has a narrow therapeutic index and is renally excreted. The dose should be reduced.
A client with obsessive-compulsive disorder may use reaction formation as a defense mechanism to cope with anxiety and stress. What typically occurs in reaction formation?
1. The client assumes an attitude that is the opposite of an impulse that the client harbors.
A client on an in-patient psychiatric unit is experiencing a flashback. Which intervention takes priority? 1. Maintain and reassure the client of his or her safety and security. 2. Encourage the client to express feelings. 3. Decrease extraneous external stimuli. 4. Use a nonjudgmental and matter-of-fact approach.
1. During a flashback, the client is experiencing severe-to-panic levels of anxiety; the priority nursing intervention is to maintain and reassure the client of his or her safety and security. The client's anxiety needs to decrease before other interventions are attempted. TEST-TAKING HINT: It is important to understand time-wise interventions when dealing with individuals experiencing anxiety. When the client experiences severe-to-panic levels of anxiety during flashbacks, the nurse needs to maintain safety and security until the client's level of anxiety has decreased.
A newly admitted client diagnosed with social phobia has a nursing diagnosis of social isolation R/T fear of ridicule. Which outcome is appropriate for this client? 1. The client will participate in two group activities by day 4. 2. The client will use relaxation techniques to decrease anxiety. 3. The client will verbalize one positive attribute about self by discharge. 4. The client will request buspirone (BuSpar) PRN to attend group by day 2.
1. Expecting the client to participate in a set number of group activities by day 4 directly relates to the stated nursing diagnosis of social isolation and is a measurable outcome that includes a timeframe. TEST-TAKING HINT: To express an appropriate outcome, the statement must be related to the stated problem, be measurable and attainable, and have a timeframe. The test taker can eliminate "2" immediately because there is no timeframe, and then "3" because it does not relate to the stated problem.
After seeking help at an outpatient mental health clinic, a client who was raped while walking her dog is diagnosed with posttraumatic stress disorder (PTSD). Three months later, the client returns to the clinic, complaining of fear, loss of control, and helpless feelings. Which nursing intervention is most appropriate for this client?
1. Exploring the meaning of the traumatic event with the client

Select all that apply. 1. Involving the family in therapy to decrease stress within the family. 2. Using phototherapy to assist the client to adapt to changes in sleep. 3. Administering medications such as tricyclic antidepressants or low-dose benzodiazepines or both. 4. Giving central nervous system stimulants, such as amphetamines. 5. Using relaxation therapy, such as meditation and deep breathing techniques, to assist the client in falling asleep.
1. Family stress can occur as the result of repeated client nightmares. This stress within the family may exacerbate the client's problem and hamper any effective treatment. Involving the family in therapy to relieve obvious stress would be an appropriate intervention to assist in the treatment of clients diagnosed with a nightmare disorder. 3. Administering medications such as tricyclic antidepressants or low-dose benzodiazepines or both is an appropriate intervention for clients diagnosed with a parasomnia disorder, such as a nightmare disorder. 5. Relaxation therapy, such as meditation and deep breathing techniques, would be appropriate for clients diagnosed with a nightmare disorder to assist in falling back to sleep after the nightmare occurs. TEST-TAKING HINT: To answer this question correctly, the test taker must be able first to understand the manifestation of a nightmare disorder and then to choose the interventions that would address these manifestations effectively.
40. The nurse enters the room as the client is beginning to have a tonic-clonic seizure. What action should the nurse implement first? 1. Note the first thing the client does in the seizure. 2. Assess the size of the client's pupils. 3. Determine if the client is incontinent of urine or stool. 4. Provide the client with privacy during the seizure.
1. Noticing the first thing the client does during a seizure provides information and clues as to the location of the seizure in the brain. It is important to document whether the beginning of the seizure was observed.
38. The occupational health nurse is concerned about preventing occupation-related acquired seizures. Which intervention should the nurse implement? 1. Ensure that helmets are worn in appropriate areas. 2. Implement daily exercise programs for the staff. 3. Provide healthy foods in the cafeteria. 4. Encourage employees to wear safety glasses.
1. Head injury is one of the main reasons for epilepsy that can be prevented through occupational safety precautions and highway safety programs.
Spironolactone (Aldactone) is prescribed for a client with hypertension. The nurse recognizes which information as providing the most support for the use of this drug? 1. Diagnosis of hepatic failure 2. Insufficient therapeutic response to hydrochlorothiazide 3. Insufficient therapeutic response to furosemide (Lasix) 4. Diagnosis of renal failure
1. Hepatic failure is accompanied by increased production of aldosterone, which increases reabsorption of sodium and water in the distal tubule and collecting ducts. Spironolactone (Aldactone) achieves a diuretic effect by blocking the effects of aldosterone. Found on page 351
The nurse notices that a client with obsessive-compulsive disorder dresses and undresses numerous times each day. Which comment by the nurse would be therapeutic?
1. I saw you change clothes several times today. That must be very tiring.
The nurse caring for a client in renal failure should question an order for which drug? 1. Ibuprofen (Advil) 800 mg three times daily 2. Erythromycin (E-Mycin) 500 mg four times daily 3. Aluminum hydroxide gel 30 ml every 4 hours as needed 4. Acetylsalicylic acid (aspirin) 162 mg daily
1. Ibuprofen (NSAID) is a nephrotoxic drug. Clients in renal failure have increased vulnerability to injury from nephrotoxic drugs.
Which nursing diagnosis reflects the intrapersonal theory of the etiology of obsessivecompulsive disorder? 1. Ineffective coping R /T punitive superego. 2. Ineffective coping R /T active avoidance. 3. Ineffective coping R /T alteration in serotonin. 4. Ineffective coping R /T classic conditioning.
1. Ineffective coping R /T punitive superego reflects an intrapersonal theory of the etiology of obsessive-compulsive disorder (OCD). The punitive superego is a concept contained in Freud's psychosocial theory of personality development. TEST-TAKING HINT: To answer this question correctly, the test taker needs to understand the different theories of the etiology of OCD. The keyword "intrapersonal" should make the test taker look for a concept inherent in this theory, such as "punitive superego."
A hospitalized client diagnosed with posttraumatic stress disorder has a nursing diagnosis of ineffective coping R /T history of rape AEB abusing alcohol. Which is the expected short-term outcome for this client problem? 1. The client will recognize triggers that precipitate alcohol abuse by day 2. 2. The client will attend follow-up weekly therapy sessions after discharge. 3. The client will refrain from self-blame regarding the rape by day 2. 4. The client will be free from injury to self throughout the shift.
1. It is a realistic expectation for a client who copes with previous trauma by abusing alcohol to recognize the triggers that precipitate this behavior. This outcome should be developed mutually early in treatment. TEST-TAKING HINT: It is important to relate outcomes to the stated nursing diagnosis. In this question, the test taker should choose an answer that relates to the nursing diagnosis of ineffective coping. Answer "4" can be eliminated immediately because it does not assist the client in coping more effectively. Also, the test taker must note important words, such as "short-term." Answer "2" can be eliminated immediately because it is a long-term outcome.
45. The client has been newly diagnosed with epilepsy. Which discharge instructions should be taught to the client? Select all that apply. 1. Keep a record of seizure activity. 2. Take tub baths only; do not take showers. 3. Avoid over-the-counter medications. 4. Have anticonvulsant medication serum levels checked regularly. 5. Do not drive alone; have someone in the car.
1. Keeping a seizure and medication chart will be helpful when keeping follow-up appointments with the health-care provider and in identifying activities that may trigger a seizure. 3. Over-the-counter medications may contain ingredients that will interact with antiseizure medications or, in some cases, as with use of stimulants, possibly cause a seizure. 4. Most of the anticonvulsant medications have therapeutic serum levels that should be maintained, and regular checks of the serum levels help to ensure the correct level.
The patient is using topical corticosteroids. The nurse will need to monitor for which of the following systemic effects of the medication? (Select all that apply.) 1. Mood changes 2. Bone defects 3. Liver toxicity 4. Adrenal insufficiency
1. Mood changes 2. Bone defects 4. Adrenal insufficiency
The nurse is managing care for a client with acute renal failure. What does the nurse recognize as the most important safety precaution with regard to medication administration? 1. Review the client's medication regimen to identify any nephrotoxic drugs. 2. Ensure that the client's fluid intake and output are measured precisely. 3. Review the client's medication regimen to identify any drugs that increase fluid retention. 4. Plan to administer less-than-average doses of all medications prescribed for the client.
1. Persons in acute renal failure are at significantly increased risk of injury from nephrotoxic drugs.
The nurse is reviewing results of a routine urinalysis that indicate the presence of protein in the urine. The nurse interprets this finding to mean that 1. The client probably has kidney damage. 2. The results are probably insignificant if the amount of protein is very small. 3. There is likely a mistake with the results, and the client should have another test done. 4. The client is in acute renal failure, and should be hospitalized.
1. Protein is always an abnormal finding on urinalysis; it indicates damage to the glomerular membrane.
When a client experiences a panic attack, which outcome takes priority? 1. The client will remain safe throughout the duration of the panic attack. 2. The client will verbalize an anxiety level less than 2/10. 3. The client will use learned coping mechanisms to decrease anxiety. 4. The client will verbalize the positive effects of exercise by day 2.
1. Remaining safe throughout the duration of the panic attack is the priority outcome for the client. TEST-TAKING HINT: All outcomes must be appropriate for the situation described in the question. In the question, the client is experiencing a panic attack; having the client verbalize the positive effects of exercise would be inappropriate. All outcomes must be client-centered, specific, realistic, positive, and measurable, and contain a timeframe.
While in the facility, a client with obsessive-compulsive disorder saves all used medicine cups and paper cups and arranges them in elaborate sculptures in the room. At home, the client saves mail and magazines and makes elaborate paper sculptures from them. Which outcome would indicate successful treatment for this client?

A client diagnosed with generalized anxiety disorder has a nursing diagnosis of panic anxiety R/T altered perceptions. Which of the following short-term outcomes is most appropriate for this client? 1. The client will be able to intervene before reaching panic levels of anxiety by discharge. 2. The client will verbalize decreased levels of anxiety by day 2. 3. The client will take control of life situations by using problem-solving methods effectively. 4. The client will voluntarily participate in group therapy activities by discharge.
1. The client's being able to intervene before reaching panic levels of anxiety by discharge is measurable, relates to the stated nursing diagnosis, has a timeframe, and is an appropriate short-term outcome for this client. TEST-TAKING HINT: When evaluating outcomes, the test taker must make sure that the outcome is specific to the client's need, is realistic, is measurable, and contains a reasonable timeframe. If any of these components is missing, the outcome is incorrectly written and can be eliminated.
The formation of urine begins at which structure? 1. Glomerulus 2. Ureter 3. Collecting duct 4. Henle's loop
1. The glomerulus is the site where filtration and production of urine begin.
The nurse is caring for a client with chronic renal failure and is assessing the client's urine output for the shift. In calculating the expected urine output, the nurse knows that the body produces _______ mL of urine per minute.
1. The kidneys produce approximately 1 mL of urine each minute.
A client diagnosed with generalized anxiety disorder complains of feeling out of control and states, "I just can't do this anymore." Which nursing action takes priority at this time? 1. Ask the client, "Are you thinking about harming yourself?" 2. Remove all potentially harmful objects from the milieu. 3. Place the client on a one-to-one observation status. 4. Encourage the client to verbalize feelings during the next group.
1. The nurse should recognize the statement, "I can't do this anymore," as evidence of hopelessness and assess further the potential for suicidal ideations. TEST-TAKING HINT: To answer this question correctly, the test taker should apply the nursing process. Assessment is the first step of this process. The nurse initially must assess a situation before determining appropriate nursing interventions.
The nurse is using a cognitive intervention to decrease anxiety during a client's panic attack. Which statement by the client would indicate that the intervention has been successful? 1. "I reminded myself that the panic attack would end soon, and it helped." 2. "I paced the halls until I felt my anxiety was under control." 3. "I felt my anxiety increase, so I took lorazepam (Ativan) to decrease it." 4. "Thank you for staying with me. It helped to know staff was there."
1. This statement is an indication that the cognitive intervention was successful. By remembering that panic attacks are self-limiting, the client is applying the information gained from the nurse's cognitive intervention. TEST-TAKING HINT: To answer this question correctly, the test taker needs to understand which interventions support which theories of causation. When looking for a "cognitive" intervention, the test taker must remember that the theory involves thought processes.
43. The client is prescribed phenytoin (Dilantin), an anticonvulsant, for a seizure disorder. Which statement indicates the client understands the discharge teaching concerning this medication? 1. "I will brush my teeth after every meal." 2. "I will check my Dilantin level daily." 3. "My urine will turn orange while on Dilantin." 4. "I won't have any seizures while on this medication."
1. Thorough oral hygiene after each meal, gum massage, daily flossing, and regular dental care are essential to prevent or control gingival hyperplasia, which is a common occurrence in clients taking Dilantin.
Lorazepam (Ativan) is often given along with a neuroleptic agent, such as haloperidol (Haldol). What is the purpose of administering the drugs together?
1. To reduce anxiety and potentiate the sedative action of the neuroleptic
A client newly admitted to an in-patient psychiatric unit is diagnosed with obsessivecompulsive disorder. Which behavioral symptom would the nurse expect to assess? 1. The client uses excessive hand washing to relieve anxiety. 2. The client rates anxiety at 8/10. 3. The client uses breathing techniques to decrease anxiety. 4. The client exhibits diaphoresis and tachycardia.
1. Using excessive hand washing to relieve anxiety is a behavioral symptom exhibited by clients diagnosed with obsessivecompulsive disorder (OCD). TEST-TAKING HINT: To answer this question correctly, the test taker must be able to differentiate various classes of symptoms exhibited by clients diagnosed with OCD. The keyword "behavioral" determines the correct answer to this question.
The nurse on the in-patient psychiatric unit should include which of the following interventions when working with a newly admitted client diagnosed with obsessivecompulsive disorder? Select all that apply. 1. Assess previously used coping mechanisms and their effects on anxiety. 2. Allow time for the client to complete compulsions. 3. With the client's input, set limits on ritualistic behaviors. 4. Present the reality of the impact the compulsions have on the client's life. 5. Discuss client feelings surrounding the obsessions and compulsions.
1. When a client is newly admitted, it is important for the nurse to assess past coping mechanisms and their effects on anxiety. Assessment is the first step in the nursing process, and this information needs to be gathered to intervene effectively. 2. Allowing time for the client to complete compulsions is important for a client who is newly admitted. If compulsions are limited, anxiety levels increase. If the client had been hospitalized for a while, then, with the client's input, limits would be set on the compulsive behaviors. 5. It is important for the nurse to allow the client to express his or her feelings about the obsessions and compulsions. This assessment of feelings should begin at admission. TEST-TAKING HINT: It is important for the test taker to note the words "newly admitted" in the question. The nursing interventions implemented vary and are based on length of stay on the unit, along with client's insight into his or her disorder. For clients with obsessive-compulsive disorder, it is important to understand that the compulsions are used to decrease anxiety. If the compulsions are limited, anxiety increases. Also, the test taker must remember that during treatment it is imperative that the treatment team includes the client in decisions related to any limitation of compulsive behaviors.

T: attention deficit-hyperactivity disorder drug P: CNS stimulant
A client diagnosed with posttraumatic stress disorder is close to discharge. Which client statement would indicate that teaching about the psychosocial cause of posttraumatic stress disorder was effective? 1. "I understand that the event I experienced, how I deal with it, and my support system all affect my disease process." 2. "I have learned to avoid stressful situations as a way to decrease emotional pain." 3. "So, natural opioid release during the trauma caused my body to become 'addicted.'" 4. "Because of the trauma, I have a negative perception of the world and feel hopeless."
1. When the client verbalizes understanding of how the experienced event, individual traits, and available support systems affect his or her diagnosis, the client demonstrates a good understanding of the psychosocial cause of posttraumatic stress disorder (PTSD). To answer this question correctly, the test taker should review the different theories as they relate to the causes of different anxiety disorders, including PTSD. Only "1" describes a psychosocial etiology of PTSD.
A client is admitted to the psychiatric unit with a diagnosis of conversion disorder. Since witnessing the beating of his wife at gunpoint, he has been unable to move his arms, complaining that they are paralyzed. When planning the client's care, the nurse should focus on:

The solution may be used to dilute mixed intravenous drugs. 3. The solution is considered a colloid solution. 4. The solution is used to provide adequate calories for metabolic needs.
2 Rationale: 5% Dextrose in water (D5W) is often used to reconstitute (dilute) powdered forms of drugs that are intended to be given parenterally.
The nurse weighs the client who is on an infusion on lactated Ringer's postoperatively and finds that there has been a weight gain of 1.5kg since the previous day. What would be the nurse's next priority? 1. Check with the client to determine whether there have been any dietary changes in the last few days. 2. Assess the client for signs of edema and BP for possible hypertension. 3. Contact dietary to change the client's diet to reduced sodium. 4. Request a diuretic from the client's provider.
2 Rationale: A weight gain of 1 kg (2 lbs) or more may indicate fluid retention. Signs of fluid retention include increased BP and edema. A complete nursing assessment is needed to determined other signs or symptoms that may be present.
Which of the following nursing interventions is most important when caring for a client receiving dextran 40 (Gentran 40)? 1. Assess the patient for deep vein thrombosis. 2. Observe for signs of fluid overload. 3. Encourage fluid intake. 4. Monitor arterial blood gases.
2 Rationale: Dextran 40 (Gentran 40) is a colloidal plasma volume expander that causes fluid to move rapidly from the tissues to vascular spaces. This places the client at risk for fluid overload.
The nurse informs a patient taking benzocaine for a minor skin irritation that benzocaine: 1. Cannot be used for sunburns 2. Should not be used on open lesions 3. Causes blisters 4. Can be used on open sores
2. Should not be used on open lesions
To prevent rupture of the sac in a patient born with myelomeningocele, which of the following treatments does the nurse anticipate? 1) Ultrasound 2) Surgical closure 3) Banding to form necrotic tissue 4) Insertion of drain to collect CSF leakage
2) Page 807.
A nurse admits a child who has a history cerebral palsy. Which assessment finding by the nurse is most concerning? 1) The mother reports the child had a seizure 5 hours ago. 2) The child has a fever of 100.3. 3) The child is standing on his toes. 4) The mother reports the child's twisting movements seem to have worsened since arriving at the clinic.
2) This fever could indicate aspiration pneumonia, and this needs to be investigated further immediately with questioning of coughing, respiratory difficulty, or sputum production. Seizures are common with cerebral palsy. The child's symptoms have likely worsened because of the stress due to a clinic visit. Standing on the toes or scooting on the back (instead of crawling on the abdomen) are both commonly seen in a patient with cerebral palsy.
The nurse is caring for a patient diagnosed with a meningocele. The nurse should perform all of the following actions except: 1) Documenting the presence of a sac protruding from the lower spinal column. 2) Documenting the presence of clear fluid draining from the meningocele. 3) Encouraging fluids hourly. 4) Measuring head circumference every shift.
2) This may indicate a CSF leak and should be reported
When assessing a child for developmental dysplasia of the hip, the nurse feels a "clunk" when the child's hip is abducted and relocated. Which of the following did the nurse perform? 1) Braxton's maneuver 2) Ortolani's sign 3) Trendelenburg's sign 4) Barlow's test
2) Barlow's is when the hip is adducted and dislocated.
The nurse is instructing a client with COPD how to do pursed-lip breathing. In which order should the nurse explain the steps to the client? 1. "Breathe in normally through your nose for 2 counts (while counting to yourself, one, two)." 2. "Relax your neck and shoulder muscles." 3. "Pucker your lips as if you were going to whistle." 4. "Breathe out slowly through pursed lips for 4 counts (while counting to yourself, one, two, three, four)."
2, 1, 3, 4. The nurse should instruct the client to first relax the neck and shoulders and then take several normal breaths. After taking a breath in, the client should pucker the lips, and finally breathe out through pursed lips.
While caring for a patient with a myelomeningocele, which of the following actions, if made by the pediatric nurse, is incorrect? Select all that apply: 1) The nurse reports the presence of clear fluid from the lesion. 2) The nurse places the child in supine position to prevent skin breakdown. 3) The nurse encourages that light-weight blankets be used in place of heavy blankets or coverings. 4) The nurse places a piece of plastic wrap below the meningocele. 5) The nurse moistens the sac with a saline-soaked piece of gauze.
2, 3 A warmer or isolette should be used in place of blankets, which may place too much pressure on the sac. Supine positioning should be avoided in patients with myelomeningocele, as this places excessive pressure on the spinal cord sac. Prone positioning is preferred.
A nurse prepares to care for a patient diagnosed with athetoid, or dyskinetic, cerebral palsy. Which of the following does the nurse expect to see? Select all that apply: 1) Hypertonicity of affected extremities 2) Drooling 3) Worsening of symptoms when the child gets stressed 4) Worm-like writhing 5) Exaggerated deep tendon reflexes

2. Support the use of appropriate defense mechanisms. 4. Explore the patterns leading to the compulsive behavior. 6. Encourage activities, such as listening to music."
A nurse has just finished providing discharge teaching to the family of a child going home with a cast that was applied 30 minutes prior. Which statement by the family indicates that further teaching is necessary? Select all that apply: 1) "For the next couple of days, we should keep the casted arm above the level of the heart and apply ice." 2) "If my child's arm starts to itch, we can apply lotion if we can reach into the cast." 3) "We will tape a plastic bag around his cast before he takes a bath." 4) "If my child gets his cast wet, we'll blow dry it with the lowest heat setting on our blow dryer." 5) "We will make sure we regularly press the skin back around the edge of the cast." 6) "We will make sure our child does not eat anything messy while he has this cast on."
2, 4, 6 Nothing should be inserted into the cast, and lotions and powders should not be used. If the cast gets wet, a blow dryer with COLD air should be used. There is no need to adjust the child's diet, but the cast should be covered while the child eats or drinks. See page 844
The nurse is assessing a client prior to the administration of a diuretic. The nurse knows it is essential to assess which vital signs at this time? Select all that apply. 1. Temperature 2. Pulse 3. Respirations 4. Blood pressure 5. Pain
2,4. The nurse must assess the client's pulse prior to administering a diuretic. The nurse must assess the client's blood pressure prior to administering a diuretic.
Which of the following is an expected outcome for an elderly client following treatment for bacterial pneumonia? 1. A respiratory rate of 25 to 30 breaths/ minute. 2. The ability to perform activities of daily living without dyspnea. 3. A maximum loss of 5 to 10 lb of body weight. 4. Chest pain that is minimized by splinting the rib cage.
2. An expected outcome for a client recovering from pneumonia would be the ability to perform activities of daily living without experiencing dyspnea. A respiratory rate of 25 to 30 breaths/ minute indicates the client is experiencing tachypnea, which would not be expected on recovery. A weight loss of 5 to 10 lb is undesirable; the expected outcome would be to maintain normal weight. A client who is recovering from pneumonia should experience decreased or no chest pain.
When performing postural drainage, which of the following factors promotes the movement of secretions from the lower to the upper respiratory tract? 1. Friction between the cilia. 2. Force of gravity. 3. Sweeping motion of cilia. 4. Involuntary muscle contractions.
2. The principle behind using postural drainage is that gravity will help move secretions from smaller to larger airways. Postural drainage is best used after percussion has loosened secretions. Coughing or suctioning is then used to remove secretions. Movement of cilia is not sufficient to move secretions. Muscle contractions do not move secretions within the lungs.
A client with bacterial pneumonia is to be started on I.V. antibiotics. Which of the following diagnostic tests must be completed before antibiotic therapy begins? 1. Urinalysis. 2. Sputum culture. 3. Chest radiograph. 4. Red blood cell count.
2. A sputum specimen is obtained for culture to determine the causative organism. After the organism is identified, an appropriate antibiotic can be prescribed. Beginning antibiotic therapy before obtaining the sputum specimen may alter the results of the test. Neither a urinalysis, a chest radiograph, nor a red blood cell count needs to be obtained before initiation of antibiotic therapy for pneumonia.
A client with chronic obstructive pulmonary disease (COPD) is experiencing dyspnea and has a low PaO2 level. The nurse plans to administer oxygen as ordered. Which of the following statements is true concerning oxygen administration to a client with COPD? 1. High oxygen concentrations will cause coughing and dyspnea. 2. High oxygen concentrations may inhibit the hypoxic stimulus to breathe. 3. Increased oxygen use will cause the client to become dependent on the oxygen. 4. Administration of oxygen is contraindicated in clients who are using bronchodilators.
2. Clients who have a long history of COPD may retain carbon dioxide (CO2). Gradually the body adjusts to the higher CO2 concentration, and the high levels of CO2 no longer stimulate the respiratory center. The major respiratory stimulant then becomes hypoxemia. Administration of high concentrations of oxygen eliminates this respiratory stimulus and leads to hypoventilation. Oxygen can be drying if it is not humidified, but it does not cause coughing and dyspnea. Increased oxygen use will not create an oxygen dependency; clients should receive oxygen as needed. Oxygen is not contraindicated with the use of bronchodilators.
The nurse reviews an arterial blood gas report for a client with chronic obstructive pulmonary disease (COPD). pH 7.35; PC02 62; PO2 70; HCO3 34 The nurse should: 1. Apply a 100% non-rebreather mask. 2. Assess the vital signs. 3. Reposition the client. 4. Prepare for intubation.
2. Clients with chronic COPD have CO2 retention and the respiratory drive is stimulated when the PO2 decreases. The heart rate, respiratory rate, and blood pressure should be evaluated to determine if the client is hemodynamically stable. Symptoms, such as dyspnea, should also be assessed. Oxygen supplementation, if indicated, should be titrated upward in small increments. There is no indication that the client is experiencing respiratory distress requiring intubation.
When teaching a client with chronic obstructive pulmonary disease to conserve energy, the nurse should teach the client to lift objects: 1. While inhaling through an open mouth. 2. While exhaling through pursed lips. 3. After exhaling but before inhaling. 4. While taking a deep breath and holding it.
2. Exhaling requires less energy than inhaling. Therefore, lifting while exhaling saves energy and reduces perceived dyspnea. Pursing the lips prolongs exhalation and provides the client with more control over breathing. Lifting after exhaling but before inhaling is similar to lifting with the breath held. This should not be recommended because it is similar to the Valsalva maneuver, which can stimulate cardiac arrhythmias.
A client's arterial blood gas values are as follows: pH, 7.31; PaO2, 80 mm Hg; PaCO2, 65 mm Hg; HCO3 −, 36 mEq/ L. The nurse should assess the client for? 1. Cyanosis. 2. Flushed skin. 3. Irritability. 4. Anxiety.
2. The high PaCO2 level causes flushing due to vasodilation. The client also becomes drowsy and lethargic because carbon dioxide has a depressant effect on the central nervous system. Cyanosis is a sign of hypoxia. Irritability and anxiety are not common with a PaCO2 level of 65 mm Hg but are associated with hypoxia.
A client is taking a diuretic for the treatment of congestive heart failure. The nurse teaches the client the importance of daily weights and knows the client understands the instruction when he states, "I will report a weight gain or loss of _____ pounds in a 24-hour period."

A patient is receiving a thrombolytic agent, alteplase (Activase), follwing an acute myocardial infraction. Which condition is most likely attributed to thrombolytic therapy with this agent? 1. Skin rash with urticaria 2. Wheezing with labored respirations 3. Brusing and epistaxis 4. Temperature elevation of 100.8F
3. Bruising and epistaxis Rationale: Thrombolytic agents dissolve existing clots rapidly and continue to have effects for 2 to 4 days. All forms of bleeding must be monitored and reported immediately. Skin rash with urticara, wheezing with labored respirations, and temperature elevation of 100.8F are not symptoms of adverse effects directly attributed to thrombolytic therapy.
A client receiving bumetanide (Bumex) asks the nurse, "What is all this about 'loops' in my medicine?" The nurse's best response is: 1. "This medication reabsorbs potassium in Henle's loop in your kidney." 2. "This medication blocks sodium reabsorption in what is known as Bowman's capsule." 3. "This is a loop diuretic, which refers to the location where it acts in your kidneys." 4. "This is a loop diuretic, which means it works in the proximal tubule of your kidney."
3. Bumetanide (Bumex) promotes sodium loss at Henle's loop, which leads to diuresis.
A client diagnosed with generalized anxiety disorder is placed on clonazepam (Klonopin) and buspirone (BuSpar). Which client statement indicates teaching has been effective? 1. The client verbalizes that the clonazepam (Klonopin) is to be used for long-term therapy in conjunction with buspirone (BuSpar). 2. The client verbalizes that buspirone (BuSpar) can cause sedation and should be taken at night. 3. The client verbalizes that clonazepam (Klonopin) is to be used short-term until the buspirone (BuSpar) takes full effect. 4. The client verbalizes that tolerance can result with long-term use of buspirone (BuSpar).
3. Clonazepam would be used for shortterm treatment while waiting for the buspirone to take full effect, which can take 4 to 6 weeks. TEST-TAKING HINT: To answer this question correctly, the test taker must note appropriate teaching needs for clients prescribed different classifications of antianxiety medications.
The nurse is assessing a client receiving chlorothiazide (Diuril), and recognizes which assessment findings as indications of hypokalemia? 1. Confusion and decreased urine output 2. General irritability and increased urine output 3. Muscle weakness or cramps 4. Diarrhea and projectile vomiting
3. Confusion might accompany hypokalemia, but decreased urine output is not a sign of hypokalemia. Neither general irritability nor increased urine output is a sign of hypokalemia. Muscle weakness and cramps are indicators of hypokalemia.
A newly admitted client is diagnosed with posttraumatic stress disorder. Which behavioral symptom would the nurse expect to assess? 1. Recurrent, distressing flashbacks. 2. Intense fear, helplessness, and horror. 3. Diminished participation in significant activities. 4. Detachment or estrangement from others.
3. Diminished participation in significant activities is a behavioral symptom of PTSD. TEST-TAKING HINT: To answer this question correctly, the test taker should take note of the keyword "behavioral," which determines the correct answer. All symptoms may be exhibited in PTSD, but only answer choice "3" is a behavioral symptom.
A client enters the crisis unit complaining of increased stress from her studies as a medical student. She states that she has been increasingly anxious for the past month. Her physician prescribes alprazolam (Xanax), 25 mg by mouth three times per day, along with professional counseling. Before administering alprazolam, the nurse reviews the client's medication history. Which drug can produce additive effects when given concomitantly with alprazolam?
3. Diphenhydramine (Benadryl)
41. The client who just had a three (3)-minute seizure has no apparent injuries and is oriented to name, place, and time but is very lethargic and just wants to sleep. Which intervention should the nurse implement? 1. Perform a complete neurological assessment. 2. Awaken the client every 30 minutes. 3. Turn the client to the side and allow the client to sleep. 4. Interview the client to find out what caused the seizure.
3. During the postictal (after-seizure) phase, the client is very tired and should be allowed to rest quietly; placing the client on the side will help prevent aspiration and maintain a patent airway.
A client diagnosed with social phobia has an outcome that states, "Client will voluntarily participate in group activities with peers by day 3." Which would be an appropriate intrapersonal intervention by the nurse to assist the client to achieve this outcome? 1. Offer PRN lorazepam (Ativan) 1 hour before group begins. 2. Attend group with client to assist in decreasing anxiety. 3. Encourage discussion about fears related to socialization. 4. Role-play scenarios that may occur in group to decrease anxiety.
3. Encouraging discussion about fears is an intrapersonal intervention. TEST-TAKING HINT: It is important to understand that interventions are based on theories of causation. In this question, the test taker needs to know that intrapersonal theory relates to feelings or developmental issues. Only "3" deals with client feelings.
A nurse observes a medical student walk into a client's room and begin questioning her about her current health status. The client appears reluctant to respond. How should the nurse intervene?
3. Explain to the client that she has the right to refuse to answer questions asked by the medical student.
Which assessment data would support a physician's diagnosis of an anxiety disorder in a client? 1. A client experiences severe levels of anxiety in one area of functioning. 2. A client experiences an increased level of anxiety in one area of functioning for a 6-month period. 3. A client experiences increased levels of anxiety that affect functioning in more than one area of life over a 6-month period. 4. A client experiences increased levels of anxiety that affect functioning in at least three areas of life.
3. For a client to be diagnosed with an anxiety disorder, the client must experience symptoms that interfere in a minimum of two areas, such as social, occupational, or other important functioning. These symptoms must be experienced for durations of 6 months or longer. TEST-TAKING HINT: To answer this question correctly, the test taker must understand that specific symptoms must be exhibited and specific timeframes achieved for clients to be diagnosed with anxiety disorders.
The nurse is caring for a client with a brain tumor who has received mannitol (Osmitrol) IV. Which laboratory finding represents a potential adverse effect of this drug? 1. Serum cholesterol 300 mg/dL 2. Serum albumin 29 mg/dL 3. Serum sodium 104 mEq/L 4. Serum amylase 820 mg/dL
3. Hyponatremia is a common adverse effect of mannitol (Osmitrol).
A client admitted to the unit is visibly anxious. When collecting data on the client, the nurse would expect to see which cardiovascular effect produced by the sympathetic nervous system?
3. Increased heart rate
The nurse has been teaching a client about spironolactone (Aldactone), and recognizes which statement as an indication that the client needs further teaching about this drug? 1. "I am really happy that I can have my cranberry juice." 2. "I am relieved that I do not have to give up my cabbage and mushrooms." 3. "Thank goodness I can still have my orange juice and bananas for breakfast." 4. "I need an apple a day to stay regular. I am glad I can still have this."
3. Orange juice and bananas are rich in potassium and should be avoided by persons taking spironolactone (Aldactone), which is a potassium-sparing diuretic.
A client with a history of generalized anxiety disorder enters the emergency department complaining of restlessness, irritability, and exhaustion. Vital signs are blood pressure 140/90 mm Hg, pulse 96, and respirations 20. Based on this assessed information, which assumption would be correct? 1. The client is exhibiting signs and symptoms of an exacerbation of generalized anxiety disorder. 2. The client's signs and symptoms are due to an underlying medical condition. 3. A physical examination is needed to determine the etiology of the client's problem. 4. The client's anxiolytic dosage needs to be increased.
3. Physical problems should be ruled out before determining a psychological cause for this client's symptoms. TEST-TAKING HINT: The test taker needs to remember that although a client may have a history of a psychiatric illness, a complete, thorough evaluation must be done before assuming exhibited symptoms are related to the psychiatric diagnosis. Many medical conditions generate anxiety as a symptom.
A client with chronic renal failure receiving hydrochlorothiazide (HCTZ) asks the nurse what the best fluid to drink to avoid dehydration is. What is the best response by the nurse? 1. "Iced tea or coffee is good." 2. "You may drink alcohol in moderation." 3. "Plain water is best." 4. "Electrolyte-replacement fluids like Gatorade are excellent."
3. Plain water is the preferred fluid for avoiding dehydration.
The health care provider has ordered hydrochlorothiazide (HCTZ) for a client in chronic renal failure. The nurse suspects the client is experiencing an ineffective response to the medication. Which adverse effect would be the most significant? 1. Hyponatremia 2. Excessive skin moisture 3. Rales 4. Hypertension
3. Rales can represent pulmonary edema, which is a life-threatening complication of chronic renal failure and fluid retention.
A client seen in an out-patient clinic for ongoing management of panic attacks states, "I have to make myself come to these appointments. It is hard because I don't know when an attack will occur." Which nursing diagnosis takes priority? 1. Ineffective breathing patterns R /T hyperventilation. 2. Impaired spontaneous ventilation R /T panic levels of anxiety. 3. Social isolation R /T fear of spontaneous panic attacks. 4. Knowledge deficit R /T triggers for panic attacks.
3. Social isolation is seen frequently with individuals diagnosed with panic attacks. The client in the question expresses anticipatory fear of unexpected attacks, which affects the client's ability to interact with others. TEST-TAKING HINT: To answer this question correctly, the test taker must link the behaviors presented in the question with the nursing diagnosis that is reflective of these behaviors. The test taker must remember the importance of time-wise interventions. Nursing interventions differ according to the degree of anxiety the client is experiencing. If the client were currently experiencing a panic attack, other interventions would be appropriate.
46. Which statement by the female client indicates that the client understands factors that may precipitate seizure activity? 1. "It is all right for me to drink coffee for breakfast." 2. "My menstrual cycle will not affect my seizure disorder." 3. "I am going to take a class in stress management." 4. "I should wear dark glasses when I am out in the sun."
3. Tension states, such as anxiety and frustration, induce seizures in some clients, so stress management may be helpful in preventing seizures.
A client diagnosed with posttraumatic stress disorder has a nursing diagnosis of disturbed sleep patterns R /T nightmares. Which evaluation would indicate that the stated nursing diagnosis was resolved? 1. The client expresses feelings about the nightmares during group. 2. The client asks for PRN trazodone (Desyrel) before bed to fall asleep. 3. The client states that the client feels rested when awakening and denies nightmares. 4. The client avoids napping during the day to help enhance sleep.
3. The client's feeling rested on awakening and denying nightmares are the evaluation data needed to support the fact that the nursing diagnosis of disturbed sleep patterns R/T nightmares has been resolved. TEST-TAKING HINT: To answer this question correctly, the test taker needs to discern evaluation data that indicate problem resolution. Answers "1," "2," and "4" all are interventions to assist in resolving the stated nursing diagnosis, not evaluation data that indicate problem resolution.
39. The client is scheduled for an electroencephalogram (EEG) to help diagnose a seizure disorder. Which preprocedure teaching should the nurse implement? 1. Tell the client to take any routine antiseizure medication prior to the EEG. 2. Tell the client not to eat anything for eight (8) hours prior to the procedure. 3. Instruct the client to stay awake for 24 hours prior to the EEG. 4. Explain to the client that there will be some discomfort during the procedure.
3. The goal is for the client to have a seizure during the EEG. Sleep deprivation, hyperventilating, or flashing lights may induce a seizure.
Using psychodynamic theory, which intervention would be appropriate for a client diagnosed with panic disorder? 1. Encourage the client to evaluate the power of distorted thinking. 2. Ask the client to include his or her family in scheduled therapy sessions. 3. Discuss the overuse of ego defense mechanisms and their impact on anxiety. 4. Teach the client about the effect of blood lactate level as it relates to the client's panic attacks.
3. The nurse discussing the overuse of ego defense mechanisms illustrates a psychodynamic approach to address the client's behaviors related to panic disorder. TEST-TAKING HINT: When answering this question, the test taker must be able to differentiate among various theoretical perspectives and their related interventions.
Clients diagnosed with obsessive-compulsive disorder commonly use which mechanism? 1. Suppression. 2. Repression. 3. Undoing. 4. Denial.
3. Undoing is a defense mechanism commonly used by individuals diagnosed with OCD. Undoing is used symbolically to negate or cancel out an intolerable previous action or experience. An individual diagnosed with OCD experiencing intolerable anxiety would use the defense mechanism of undoing to undo this anxiety by substituting obsessions or compulsions or both. Other commonly used defense mechanisms are isolation, displacement, and reaction formation. TEST-TAKING HINT: To answer this question correctly, the test taker needs to understand the underlying reasons for the ritualistic behaviors used by individuals diagnosed with OCD.
A client with obsessive-compulsive disorder and ritualistic behavior must brush the hair back from his forehead 15 times before carrying out any activity. The nurse notices that the client's hair is thinning and the skin on the forehead is irritated — possible effects of this ritual. When planning the client's care, the nurse should assign highest priority to:
3. setting consistent limits on the ritualistic behavior if it harms the client or others.
The nurse is caring for a client experiencing an anxiety attack. Appropriate nursing interventions include:
3. staying with the client and speaking in short sentences.
509. An adult client was burned in an explosion. The burn initially affected the client's entire face (anterior half of the head) and the upper half of the anterior torso, and there were circumferential burns to the lower half of both arms. The client's clothes caught on fire, and the client ran, causing subsequent burn injuries to the posterior surface of the head and the upper half of the posterior torso. Using the rule of nines, what would be the extent of the burn injury? 1.18% 2.24% 3.36% 4.48%

Which diagnostic exam does the nurse know will best aid in the diagnosis of Duchenne muscular dystrophy? 1) EEG 2) CT Scan 3) MRI 4) EMG
4)
The day shift pediatric nurse receives report on the following 4 patients. After receiving report, which patient should the nurse assess first? 1) The 4-year-old female with cerebral palsy who admits with difficulty swallowing and a fever of 101.9. 2) The 9-month-old male with myelomeningocele who has absent deep tendon reflexes in bilateral lower extremities. 3) The 6-year-old male with Duchenne muscular dystrophy who appears sad and withdrawn. 4) The 7-year-old female with a spinal cord injury who reports numbness and tingling in her feet.
4) Spinal cord injury is a medical emergency that requires immediate assessment. A fever and difficulty swallowing in a child with cerebral palsy may indicate aspiration pneumonia, so this child should be seen next. Absent deep tendon reflexes are expected in a child with myelomeningocele, related to the paralysis seen below the sac. A child with Duchenne muscular dystrophy may be sad or withdrawn due to corticosteroid medication side effects or chronicity of the disease.
A concerned mother calls the and tells you the following pieces of information about her 2-year-old son. Which statement by the mother most concerns you? 1) "I noticed that when my son is standing, his knees touch but his feet seem really far apart." 2) "My son's feet are so flat, even though he's been waking for 9 months now." 3) "My baby really hates it when I try to feed him broccoli and keeps spitting it out onto his plate." 4) "This morning when I was trying to dress him, my son cried nonstop when I tried to put his shirt on."
4) This could indicate a sprain or fracture, and nursemaid's elbow is common in toddlers and preschoolers. This statement should be further investigated since it indicates pain/discomfort. It is not uncommon for infants to have flat feet, although the arch of the foot should begin to form after walking begins. However, some infants never develop an arch and have flat feet as adults. Genu valgum, or "knock knees", are commonly seen around the ages 2-3, and this will often resolve by ages 7-8. It is not uncommon for a toddler to dislike broccoli. Who does like broccoli.
The mother of a 3 month old infant calls the clinic and says "why can't my baby hold his head up? Is he developmentally delayed?" Which response by the nurse is best? 1) "Your child is unlikely to be developmentally delayed, but we would like you to come to the clinic for a well-baby check-up." 2) "Infants do not typically hold their heads up on their own before age 6 months, so you have nothing to worry about." 3) "You sound very concerned. This may indicate a developmental delay, but we would like you to come to the clinic for a well-baby check-up and testing." 4) "Your infant may not hold his head up for a couple more months. This is nothing to be concerned about."
4) This isn't an ideal answer, and could be worded more therapeutically, but out of the four options, this is the BEST answer. Infants lose head lag around 4-5 months.
Which of the following is an expected outcome of pursed-lip breathing for clients with emphysema? 1. To promote oxygen intake. 2. To strengthen the diaphragm. 3. To strengthen the intercostal muscles. 4. To promote carbon dioxide elimination.
4. Pursed-lip breathing prolongs exhalation and prevents air trapping in the alveoli, thereby promoting carbon dioxide elimination. By prolonging exhalation and helping the client relax, pursed-lip breathing helps the client learn to control the rate and depth of respiration. Pursed-lip breathing does not promote the intake of oxygen, strengthen the diaphragm, or strengthen intercostal muscles.
Furosemide (Lasix) classes
T: drug for HTN and HF P: loop diuretic
The cyanosis that accompanies bacterial pneumonia is primarily caused by which of the following? 1. Decreased cardiac output. 2. Pleural effusion. 3. Inadequate peripheral circulation. 4. Decreased oxygenation of the blood.
4. A client with pneumonia has less lung surface available for the diffusion of gases because of the inflammatory pulmonary response that creates lung exudate and results in reduced oxygenation of the blood. The client becomes cyanotic because blood is not adequately oxygenated in the lungs before it enters the peripheral circulation. Decreased cardiac output may be a comorbid condition in some clients with pneumonia; however, it is not the cause of cyanosis. Pleural effusions are a potential complication of pneumonia but are not the primary cause of decreased oxygenation. Inadequate peripheral circulation is also not the cause of the cyanosis that develops with bacterial pneumonia.
Which of the following is an appropriate expected outcome for an adult client with well-controlled asthma? 1. Chest X-ray demonstrates minimal hyperinflation. 2. Temperature remains lower than 100 ° F (37. 8 ° C). 3. Arterial blood gas analysis demonstrates a decrease in PaO2. 4. Breath sounds are clear.
4. Between attacks, breath sounds should be clear on auscultation with good air flow present throughout lung fields. Chest X-rays should be normal. The client should remain afebrile. Arterial blood gases should be normal.
When instructing clients on how to decrease the risk of chronic obstructive pulmonary disease (COPD), the nurse should emphasize which of the following? 1. Participate regularly in aerobic exercises. 2. Maintain a high-protein diet. 3. Avoid exposure to people with known respiratory infections. 4. Abstain from cigarette smoking.
4. Cigarette smoking is the primary cause of COPD. Other risk factors include exposure to environmental pollutants and chronic asthma. Participating in an aerobic exercise program, although beneficial, will not decrease the risk of COPD. Insufficient protein intake and exposure to people with respiratory infections do not increase the risk of COPD.
The nurse assesses the respiratory status of a client who is experiencing an exacerbation of chronic obstructive pulmonary disease (COPD) secondary to an upper respiratory tract infection. Which of the following findings would be expected? 1. Normal breath sounds. 2. Prolonged inspiration. 3. Normal chest movement. 4. Coarse crackles and rhonchi.
4. Exacerbations of COPD are commonly caused by respiratory infections. Coarse crackles and rhonchi would be auscultated as air moves through airways obstructed with secretions. In COPD, breath sounds are diminished because of an enlarged anteroposterior diameter of the chest. Expiration, not inspiration, becomes prolonged. Chest movement is decreased as lungs become overdistended.
A 34-year-old female with a history of asthma is admitted to the emergency department. The nurse notes that the client is dyspneic, with a respiratory rate of 35 breaths/ minute, nasal flaring, and use of accessory muscles. Auscultation of the lung fields reveals greatly diminished breath sounds. Based on these findings, which action should the nurse take to initiate care of the client? 1. Initiate oxygen therapy and reassess the client in 10 minutes. 2. Draw blood for an arterial blood gas analysis and send the client for a chest X-ray. 3. Encourage the client to relax and breathe slowly through the mouth. 4. Administer bronchodilators.
4. In an acute asthma attack, diminished or absent breath sounds can be an ominous sign indicating lack of air movement in the lungs and impending respiratory failure. The client requires immediate intervention with inhaled bronchodilators, I.V. corticosteroids and, possibly, I.V. theophylline (Theo-Dur). Administering oxygen and reassessing the client 10 minutes later would delay needed medical intervention, as would drawing blood for an arterial blood gas analysis and obtaining a chest X-ray. It would be futile to encourage the client to relax and breathe slowly without providing the necessary pharmacologic intervention.
Which of the following indicates that the client with chronic obstructive pulmonary disease (COPD) who has been discharged to home understands his care plan? 1. The client promises to do pursed-lip breathing at home. 2. The client states actions to reduce pain. 3. The client says that he will use oxygen via a nasal cannula at 5 L/ minute. 4. The client agrees to call the physician if dyspnea on exertion increases.
4. Increasing dyspnea on exertion indicates that the client may be experiencing complications of COPD. Therefore, the nurse should notify the physician. Extracting promises from clients is not an outcome criterion. Pain is not a common symptom of COPD. Clients with COPD use low-flow oxygen supplementation (1 to 2 L/ minute) to avoid suppressing the respiratory drive, which, for these clients, is stimulated by hypoxia. .
Which of the following diets would be most appropriate for a client with chronic obstructive pulmonary disease (COPD)? 1. Low-fat, low-cholesterol diet. 2. Bland, soft diet. 3. Low-sodium diet. 4. High-calorie, high-protein diet.
4. The client should eat high-calorie, high-protein meals to maintain nutritional status and prevent weight loss that results from the increased work of breathing. The client should be encouraged to eat small, frequent meals. A low-fat, low-cholesterol diet is indicated for clients with coronary artery disease. The client with COPD does not necessarily need to follow a sodium-restricted diet, unless otherwise medically indicated. There is no need for the client to eat bland, soft foods.
Which of the following measures would most likely be successful in reducing pleuritic chest pain in a client with pneumonia? 1. Encourage the client to breathe shallowly. 2. Have the client practice abdominal breathing. 3. Offer the client incentive spirometry. 4. Teach the client to splint the rib cage when coughing.
4. The pleuritic pain is triggered by chest movement and is particularly severe during coughing. Splinting the chest wall will help reduce the discomfort of coughing. Deep breathing is essential to prevent further atelectasis. Abdominal breathing is not as effective in decreasing pleuritic chest pain as is splinting of the rib cage. Incentive spirometry facilitates effective deep breathing but does not decrease pleuritic chest pain.
During the admission data collection, a client with a panic disorder begins to hyperventilate and says, "I'm going to die if I don't get out of here right now!" What is the nurse's best response?
4. ""You're having a panic attack. I'll stay here with you
The nurse is caring for a client with sodium retention that has resulted in hypervolemia. The nurse knows that even a 1% increase in sodium is equivalent to _____ lb of fluid weight gain.
4. A 1% increase in sodium reabsorption (retention) could potentially cause a 1.8-L net gain of water each day, which is equivalent to 4 lb of body weight.
Hydrochlorothiazide (Microzide) classes
T: drug for HTN and edema P: thiazide diuretic
The nurse teaches an anxious client diagnosed with posttraumatic stress disorder a breathing technique. Which action by the client would indicate that the teaching was successful? 1. The client eliminates anxiety by using the breathing technique. 2. The client performs activities of daily living independently by discharge. 3. The client recognizes signs and symptoms of escalating anxiety. 4. The client maintains a 3/10 anxiety level without medications.
4. A client's ability to maintain an anxiety level of 3/10 without medications indicates that the client is using breathing techniques successfully to reduce anxiety. TEST-TAKING HINT: To answer this question correctly, the test taker should understand that anxiety cannot be eliminated from life. This understanding would eliminate "1" immediately.
In which situation would the nurse suspect a medical diagnosis of social phobia? 1. A client abuses marijuana daily and avoids social situations because of fear of humiliation. 2. An 8-year-old child isolates from adults because of fear of embarrassment, but has good peer relationships in school. 3. A client diagnosed with Parkinson's disease avoids social situations because of embarrassment regarding tremors and drooling. 4. A college student avoids taking classes that include an oral presentation because of fear of being scrutinized by others.
4. A student who avoids classes because of the fear of being scrutinized by others meets the criteria for a diagnosis of social phobia. TEST-TAKING HINT: The test taker must understand the DSM-IV-TR diagnostic criteria for social phobia to answer this question correctly.
During a panic attack, a client hyperventilates, becomes unable to speak, and reports symptoms that mimic those of a heart attack. Which nursing intervention would be best?
4. Accompany the client to his room; remain there and provide instructions in short, simple statements.
During an assessment, a client diagnosed with generalized anxiety disorder rates anxiety as 9/10 and states, "I have thought about suicide because nothing ever seems to work out for me." Based on this information, which nursing diagnosis takes priority? 1. Hopelessness R /T anxiety AEB client's stating, "Nothing ever seems to work out." 2. Ineffective coping R /T rating anxiety as 9/10 AEB thoughts of suicide. 3. Anxiety R /T thoughts about work AEB rates anxiety 9/10. 4. Risk for suicide R /T expressing thoughts of suicide.
4. Because the client is expressing suicidal ideations, the nursing diagnosis of risk for suicide takes priority at this time. Client safety is prioritized over all other client problems. TEST-TAKING HINT: When looking for a priority nursing diagnosis, the test taker always must prioritize client safety. Even if other problems exist, client safety must be ensured.
A client was admitted to an in-patient psychiatric unit 4 days ago for the treatment of obsessive-compulsive disorder. Which outcome takes priority for this client at this time? 1. The client will use a thought-stopping technique to eliminate obsessive/compulsive behaviors. 2. The client will stop obsessive and/or compulsive behaviors. 3. The client will seek assistance from the staff to decrease obsessive or compulsive behaviors. 4. The client will use one relaxation technique to decrease obsessive or compulsive behaviors.
4. By day 4, it would be realistic to expect the client to use one relaxation technique to decrease obsessive or compulsive behaviors. This would be the current priority outcome. TEST-TAKING HINT: The test taker must recognize the importance of time-wise interventions when establishing outcomes. In the case of clients diagnosed with obsessive-compulsive disorder, expectations on admission vary greatly from outcomes developed closer to discharge.
From a cognitive theory perspective, which is a possible cause of panic disorder? 1. Inability of the ego to intervene when conflict occurs. 2. Abnormal elevations of blood lactate and increased lactate sensitivity. 3. Increased involvement of the neurochemical norepinephrine. 4. Distorted thinking patterns that precede maladaptive behaviors.
4. Distorted thinking patterns that precede maladaptive behaviors relate to the cognitive theory perspective of panic disorder development. TEST-TAKING HINT: The test taker should note important words in the question, such as "cognitive." Although all of the answers are potential causes of panic disorder development, the only answer that is from a cognitive perspective is "4."
Victims of sexual assault can experience posttraumatic stress reactions after the attack. Which of the following statements best describes symptoms associated with posttraumatic stress disorder (PTSD)?
4. Flashbacks, recurring dreams, and numbness
Mannitol (Osmitrol) is ordered to be administered IV to a client. The nurse will question the order for this drug if which manifestation is noted? 1. Mental confusion and elevated blood pressure 2. Fatigue and dizziness 3. Urinary output of 68 ml over 2 hours following administration of a test dose of mannitol (Osmitrol) 4. Urinary output of 45 ml over the previous 24 hours
4. Mannitol (Osmitrol) is contraindicated in the presence of anuria. Anuria is failure of the kidneys to produce urine. The normal urine output is 800-2000 ml in 24 hour period.
(SELECT ALL THAT APPLY) A registered nurse caring for a client with generalized anxiety disorder identifies a nursing diagnosis of Anxiety.

A newly admitted client diagnosed with posttraumatic stress disorder is exhibiting recurrent flashbacks, nightmares, sleep deprivation, and isolation from others. Which nursing diagnosis takes priority? 1. Posttrauma syndrome R /T a distressing event AEB flashbacks and nightmares. 2. Social isolation R /T anxiety AEB isolating because of fear of flashbacks. 3. Ineffective coping R /T flashbacks AEB alcohol abuse and dependence. 4. Risk for injury R /T exhaustion because of sustained levels of anxiety.
4. Risk for injury is the priority nursing diagnosis for this client. In the question, the client is exhibiting recurrent flashbacks, nightmares, and sleep deprivation that can cause exhaustion and lead to injury. It is important for the nurse to prioritize the nursing diagnosis that addresses safety. TEST-TAKING HINT: When the question asks for a priority, it is important for the test taker to understand that all answer choices may be appropriate statements. Client safety always should be prioritized.
Counselors have been sent to a location that has experienced a natural disaster to assist the population to deal with the devastation. This is an example of __________________ prevention.
4. Sending counselors to a natural disaster site to assist individuals to deal with the devastation is an example of primary prevention. Primary prevention reduces the incidence of mental disorders, such as posttraumatic stress disorder, within the population by helping individuals to cope more effectively with stress early in the grieving process. Primary prevention is extremely important for individuals who experience any traumatic event, such as a rape, war, hurricane, tornado, or school shooting. TEST-TAKING HINT: To answer this question correctly, it is necessary to understand the differences between primary, secondary, and tertiary prevention.
The nurse is helping to create a teaching plan for a patient prescribed desoximetasone (Topicort) for atopic dermatitis. The nurse will include which adverse effect in that plan? 1. Localized pruritus and hives 2. Hair loss in the application area 3. Worsening of acne 4. Skin irritation and redness in the application area
4. Skin irritation and redness in the application area
Which of the following statements explains the etiology of obsessive-compulsive disorder (OCD) from a biological theory perspective? 1. Individuals diagnosed with OCD have weak and underdeveloped egos. 2. Obsessive and compulsive behaviors are a conditioned response to a traumatic event. 3. Regression to the pre-Oedipal anal sadistic phase produces the clinical symptoms of OCD. 4. Abnormalities in various regions of the brain have been implicated in the cause of OCD.
4. The belief that abnormalities in various regions of the brain cause OCD is an explanation of OCD etiology from a biological theory perspective. TEST-TAKING HINT: To answer this question correctly, the test taker must understand the different theories of OCD etiology. This question calls for a biological theory perspective, making "4" the only correct choice.
A client diagnosed with posttraumatic stress disorder states to the nurse, "All those wonderful people died, and yet I was allowed to live." Which is the client experiencing? 1. Denial. 2. Social isolation. 3. Anger. 4. Survivor's guilt.
4. The client in the question is experiencing survivor's guilt. Survivor's guilt is a common situation that occurs when an individual experiences a traumatic event in which others died and the individual survived. TEST-TAKING HINT: To answer this question correctly, the test taker needs to understand common phenomena experienced by individuals diagnosed with posttraumatic stress disorder and relate this understanding to the client statement presented in the question.
37. The male client is sitting in the chair and his entire body is rigid with his arms and legs contracting and relaxing. The client is not aware of what is going on and is making guttural sounds. Which action should the nurse implement first? 1. Push aside any furniture. 2. Place the client on his side. 3. Assess the client's vital signs. 4. Ease the client to the floor. Company. Kindle Edition.
4. The client should not remain in the chair during a seizure. He should be brought safely to the floor so that he will have room to move the extremities.
The nurse's understanding of the clotting mechanism is important in administering anticoagulant drugs. the nurse understands that which of the following clotting factors are formed after injury to the vessels? 1. Fibrin, vitamin K 2. Thromboplastin, fibrinogen 3. Prothrombin, thrombin 4. Thrombin, fibrin
4. Thrombin, fibrin
The nurse receives the patient's lab values throughout warfarin drug therapy. The expected therapeutic level is: 1. aPTT of three to four times the normal control value 2. aPTT one to two times the patient's baseline level 3. aPT one to two times the patient's last result 4. aPT one and half to two and half times the control value.
4. aPT one and half to two and half times the control values. Rationale: aPT is the coagulation study that monitors oral anticoagulant use, such as warfarin. As a result of one and half to two and half times the control value indicates adquate anticoagulation. aPTT is the coagulation study that monitors heparin use. aPT level of one would indicate a less than therapeutic level of anticoagulation.
The nurse discovers that a client with obsessive-compulsive disorder (OCD) is attempting to resist the compulsion. Based on this finding, the nurse should look for signs of:
4. increased anxiety.
515.A client arrives at the emergency department following a burn injury that occurred in the basement at home, and an inhalation injury is suspected.

The nurse is administering furosemide (Lasix) IV to client with congestive heart failure. The nurse knows that the anticipated onset of action is within ____ minutes.
5. Furosemide is frequently used in the treatment of acute edema associated with liver cirrhosis, renal impairment, or congestive heart failure because it has the ability to remove large amounts of edema fluid from the client in a short time. When given IV, diuresis begins within 5 minutes, providing clients quick relief from their symptoms.
Diphenhydramine (Benadryl) classes
T: drug to treat allergies P: H1 receptor antagonisti, antihistamine
The nurse is instructing a client who is going home on diuretic therapy for the treatment of fluid retention caused by hypertension. The nurse instructs the client to stop the med and notify a HCP if the BP falls below 90/____ mmHg.
60. The nurse instructs the client to stop taking the medication if BP is 90/60 mmHg or below, or is below the parameters set by the health care provider, and promptly notify the provider.
A patient is brought to the emergency department with shortness of breath, a respiratory rate of 30 breaths per minute, intercostal retractions, and frothy, pink sputum. The nurse caring for this patient will expect to administer which drug? a. Furosemide [Lasix] b. Hydrochlorothiazide [HydroDIURIL] c. Mannitol [Osmitrol] d. Spironolactone [Aldactone]
A Furosemide, a potent diuretic, is used when rapid or massive mobilization of fluids is needed. This patient shows severe signs of congestive heart failure with respiratory distress and pulmonary edema and needs immediate mobilization of fluid. Hydrochlorothiazide and spironolactone are not indicated for pulmonary edema, because their diuretic effects are less rapid. Mannitol is indicated for patients with increased intracranial pressure and must be discontinued immediately if signs of pulmonary congestion or heart failure occur.
An older adult patient with congestive heart failure develops crackles in both lungs and pitting edema of all extremities. The physician orders hydrochlorothiazide [HydroDIURIL]. Before administering this medication, the nurse reviews the patient's chart. Which laboratory value causes the nurse the most concern? a. Elevated creatinine clearance b. Elevated serum potassium level c. Normal blood glucose level d. Low levels of low-density lipoprotein (LDL) cholesterol
A Hydrochlorothiazide should not be given to patients with severe renal impairment; therefore, an elevated creatinine clearance would cause the most concern. Thiazide diuretics are potassium-wasting drugs and thus may actually improve the patient's potassium level. Thiazides may elevate the serum glucose level in diabetic patients. Thiazides increase LDL cholesterol; however, this patient's levels are low, so this is not a risk.
A patient who was in a motor vehicle accident sustained a severe head injury and is brought into the emergency department. The provider orders intravenous mannitol [Osmitrol]. The nurse knows that this is given to: a. reduce intracranial pressure. b. reduce renal perfusion. c. reduce peripheral edema. d. restore extracellular fluid.
A Mannitol is an osmotic diuretic that is used to reduce intracranial pressure by relieving cerebral edema. The presence of mannitol in blood vessels in the brain creates an osmotic force that draws edematous fluid from the brain into the blood. Mannitol can also be used to increase renal perfusion. It can cause peripheral edema and is not used to restore extracellular fluid.
A patient receiving valproic acid (Depakote) should be monitored for which adverse effects? (Select all that apply.) A. Tremors B. Insomnia C. Hepatoxicity D. Weight gain E. Hypoglycemia
A, C, D

What is a priority nursing intervention? a. Monitor client for potential chest pain. b. Monitor blood pressure continuously. c. Assess daily for hyperkalemia. d. Assess 12-lead ECG each shift.
Besides having diuretic effects for patients with congestive heart failure, thiazides are also used to treat what? (Select all that apply.) a. Diabetes insipidus b. Hepatic failure c. Increased intracranial pressure d. Intraocular pressure e. Postmenopausal osteoporosis
A, B, E Thiazide diuretics have the paradoxical effect of reducing urine output in patients with diabetes insipidus. They can also be used to mobilize edema associated with liver disease. They promote tubular reabsorption of calcium, which may reduce the risk of osteoporosis in postmenopausal women. Mannitol is used to treat edema that causes increased intracranial pressure and intraocular pressure.
The nurse is caring for a 46-year-old female patient during the first 12 hours after a thermal burn injury. She weighed 71 kg on admission to the burn unit. Which outcomes if observed by the nurse would indicate adequate fluid resuscitation? (select all that apply) A. Urine output is 80 mL/hour. B. Heart rate is 86 beats/minute. C. Urine specific gravity is 1.025. D. Mean arterial pressure is 54 mm Hg. E. Systolic blood pressure is 88 mm Hg.
A, B, C A. Urine output is 80 mL/hour. B. Heart rate is 86 beats/minute. C. Urine specific gravity is 1.025. Assessment of the adequacy of fluid resuscitation is best made using either urine output or cardiac factors. Urine output should be at least 0.5 to 1 mL/kg/hr. Cardiac factors include a mean arterial pressure (MAP) > 65 mm Hg, systolic blood pressure (BP) > 90 mm Hg, heart rate < 120 beats/minute. Normal range for urine specific gravity is 1.003 to 1.030.
What patient education should be included for a patient receiving enoxaparin (Lovenox)? (Select all that apply.) A: Teach the patient or family to give subcutaneous injections at home. B: Teach the patient or family not to take any over-the-counter drugs without first consulting with the health care provider. C: Teach the patient to observe for unexplained bleeding such as pink, red, or dark brown urine or bloody gums. D: Teach the patient to monitor for the development of deep vein thrombosis. E: Teach the patient about the importance of drinking grapefruit juice daily.
A, B, C, D. Enoxaparin is an LMWH. Patients and family can be taught to give subcutaneous injections at home. Teaching should include instructions to not take any other medications without first consulting the health care provider and recognizing the signs and symptoms of bleeding. Enoxaparin is given to prevent development of DVT. Patients should be taught signs and symptoms of DVT to observe for and should contact their health care provider immediately if these develop or worsen while on enoxaparin therapy. Option E is incorrect. Grapefruit juice is known to alter the metabolism of many drugs in the liver. Even though the enoxaparin is given parenterally, it is metabolized in the liver and may be affected by compounds in the grapefruit juice.
The nurse is monitoring the patient for early signs of lithium (Eskalith) toxicity. Which symptoms, if present, may indicate that toxicity is developing? (Select all that apply.) A. Persistent gastrointestinal upset (e.g., nausea, vomiting) B. Confusion C. Increased urination D. Convulsions E. Ataxia
A, B, C. Persistent GI upset such as nausea, vomiting, and abdominal pain; increased urination; and confusion are signs of elevated lithium levels and may signal the early stages of toxicity. Options D and E are incorrect. Convulsions and ataxia may occur later in lithium toxicity.
After trying many other treatments, a 28-year-old female is started on isotretinoin for treatment of severe acne. While she is on this medication, what explicit instructions must be followed? (Select all that apply.) A: She must use two forms of birth control and have pregnancy tests before beginning, during, and after she is on the therapy. B: She must have vision checks performed every 6 months. C: She must increase intake of vitamin A-rich foods. D: She must return every 2 to 3 months for laboratory tests. E: She must delay any future pregnancies for a period of 5 years.
A, B, D. Isotretinoin is teratogenic and pregnancy must be avoided while on this medication. To be eligible for treatment, female patients must agree to frequent pregnancy tests and commit to using two forms of birth control while on the drug. Because of adverse visual, hepatic, and lipid effects, periodic vision screening and laboratory work must be monitored. Options C and E are incorrect. Isotretinoin is a retinoid closely related to vitamin A. Vitamin A may be toxic when taken in large doses. Normal daily intake is usually sufficient to meet the body's needs without supplementation. Women must not become pregnant while taking isotretinoin but do not have to wait 5 years after taking the drug to become pregnant.
Which of the following medications may be used to treat partial seizures? (Select all that apply.) A. Phenytoin (Dilantin) B. Valproic acid (Depakene) C. Diazepam (Valium) D. Carbamazepine (Tegretol) E. Ethosuximide (Zarontin)
A, B, D. The phenytoin-like drugs including phenytoin (Dilantin), valproic acid (Depakene), and carbamazepine (Tegretol) are used to treat partial seizures. Options C and E are incorrect. Diazepam (Valium) is a benzodiazepine that is used to treat tonic-clonic seizures and status epilepticus. Ethosuximide (Zarontin) is used in the control of generalized seizures such as absence seizures.
A patient with a congenital coagulation disorder is given aminocaproic acid (Amicar) to stop bleeding following surgery. The nurse will carefully monitor this patient for development of which of the following adverse effects? (Select all that apply.) A: Anaphylaxis B: Hypertension C: Hemorrhage D: Headache E: Hypotension
A, D, E. Adverse effects of aminocaproic acid (Amicar) include headache, anaphylaxis, and hypotension. Options B and C are incorrect. Aminocaproic acid is given to prevent excessive bleeding and hemorrhage in patients with clotting disorders. It may cause hypotension, not HTN.
A patient is receiving treatment for asthma with albuterol (Proventil). The nurse teaches the patient that while serious adverse effects are uncommon, the following may occur. (Select all that apply.) A. Tachycardia B. Sedation C. Temporary dyspnea D. Nervousness E. Headache
A, D, E. Tachycardia, nervousness, and headache may occur with the use of albuterol (Proventil, VoSpire) inhalers. Options B and C are incorrect. Sedation and dyspnea are not adverse effects of albuterol.
Which medication is indicated for suppression of cough? A. Benzonatate (Tessalon) B. Guaifenesin (Mucinex) C. Acetylcysteine (Mucomyst) D. Fluticasone furoate (Flonase)
A. Benzonatate suppresses cough by reducing the sensitivity of respiratory stretch receptors (components of the cough reflex pathway). Acetylcysteine reacts directly with mucus to make it more watery and is administered by inhalation treatment. Guaifenesin is an expectorant. Fluticasone furoate is an intranasal glucocorticoid used to treat the clinical manifestations of allergic rhinitis.
The parent of a pediatric patient with nasal stuffiness and congestion asks a nurse about cold remedies. Which additional information is the priority for the nurse to obtain? A. Age B. Developmental stage C. Body weight D. Swallowing ability
A. Cold remedies should not be used for children younger than 2 years because of the risk of harm with little evidence of efficacy. In 2008, the U.S. Food and Drug Administration (FDA) recommended that over-the-counter (OTC) cold remedies no longer be given to children younger than 2 years because of the risk of life-threatening events. Safety is still being reviewed for children ages 2 to 11 years. Developmental stage, body weight, and swallowing ability are secondary considerations with dosing of cold remedies for children.
A nurse should monitor more frequently the blood pressure of a patient with a history of hypertension who takes which medication for allergic rhinitis? A. Pseudoephedrine (Sudafed) B. Montelukast (Singulair) C. Mometasone (Nasonex spray) D. Oxymetazoline (Afrin spray)
A. Pseudoephedrine is a sympathomimetic that activates alpha1 receptors and causes vasoconstriction. Only oral agents cause widespread vasoconstriction that warrants caution in patients with hypertension. Montelukast blocks leukotrienes and has no adverse effects. Oxymetazoline spray is a topical sympathomimetic that causes rebound congestion with prolonged use. Mometasone spray is a glucocorticoid intranasal spray for which systemic side effects are rare.
The nurse completes medication education for the client receiving antihistamines. The nurse evaluates that learning has occurred when the client makes which statement? Select one: A. "This medication could make me very sleepy." B. "I can still have my after-dinner drink." C. "I need to increase fluids while taking this medication." D. "This medication is safe because it is sold over-the-counter (OTC)."
A. "This medication could make me very sleepy."
A patient has taken metaproterenol. What is the nurse's priority action? A) Monitoring for heart rate > 100 beats/min. B) Telling the patient not to drive for 2 h. C) Monitoring for sedation. D) Assessing for elevated blood pressure.

Administer through peripheral IV sites only. C. Monitor blood pressure and pulse oximetry. D. Obtain an infusion pump for the medication.
A. Flush the line with normal saline before and after administration to prevent precipitation.
A 65-year-old patient is prescribed ipratropium (Atrovent) for the treatment of asthma. Which of the following conditions should be reported to the health care provider before giving this patient the ipratropium? A. A reported allergy to peanuts B. A history of intolerance to albuterol (Proventil) C. A history of bronchospasms D. A reported allergy to chocolate
A. Ipratropium (Atrovent) is contraindicated in patients with hypersensitivity to soya lecithin or related food products such as soybean and peanut. Options B, C, and D are incorrect. A history of intolerance to albuterol or bronchospasms is an indication for ipratropium. A history of allergy to chocolate is not a contraindication for this drug.
The nurse is planning to change the dressing that covers a deep partial-thickness burn of the right lower leg. Which prescribed medication should the nurse administer to the 70-year-old female patient 30 minutes before the scheduled dressing change? A. Morphine sulfate B. Sertraline (Zoloft) C. Zolpidem (Ambien) D. Enoxaparin (Lovenox)
A. Morphine sulfate Deep partial-thickness burns result in severe pain related to nerve injury. The nurse should plan to administer analgesics before the dressing change to promote patient comfort. Morphine is a common opioid used for pain control. Sedative/hypnotics and antidepressant agents also can be given with analgesics to control the anxiety, insomnia, and/or depression that patients may experience. Zolpidem promotes sleep. Sertraline is an antidepressant. Enoxaparin is an anticoagulant.
While completing discharge teaching for a patient prescribed an antiepileptic drug, the nurse instructs the patient of which potential complication if the medication is stopped abruptly? A. Rebound seizure activity B. Orthostatic hypotension C. Acute withdrawal syndrome D. Confusion and delirium
A. Rebound seizure activity

What will the best assessment by the nurse reveal? Select one: A. The client may develop a hypertensive crisis. B. The client may develop seizures. C. The depression will not subside. D. The diphenhydramine (Benadryl) will not control allergies.
A. The client may develop a hypertensive crisis.
The nurse is providing education for a 12-year-old patient with partial seizures currently prescribed valproic acid (Depakene). The nurse will teach the patient and the parents to immediately report which symptom? A. Increasing or severe abdominal pain B. Decreased or foul taste in the mouth C. Pruritus and dry skin D. Bone and joint pain
A. Valproic acid may cause life-threatening pancreatitis, and any severe or increasing abdominal pain should be reported immediately. Options B, C, and D are incorrect. The drug is not known to cause dysgeusia (altered sense of taste) or effects on bones or joints. Although pruritus is an adverse effect associated with valproic acid, it may be managed with simple therapies, and unless it progresses to a more serious rash, it does not need to be reported immediately.
A 16-year-old patient has taken an overdosage of citalopram (Celexa) and is brought to the emergency department. What symptoms would the nurse expect to be present? A; Seizures, hypertension, tachycardia, extreme anxiety B. Hypotension, bradycardia, hypothermia, sedation C. Miosis, respiratory depression, absent bowel sounds, hypoactive reflexes D. Manic behavior, paranoia, delusions, tremors
A.An overdose of citalopram (Celexa) causes symptoms similar to serotonin syndrome including seizures, hypertension, tachycardia, and extreme anxiety. Options B, C, and D are incorrect. These are not symptoms of an SSRI overdose.
Which of the following actions by the nurse is most important when caring for a patient with renal disease who has an order for furosemide (Lasix)? A: Assess urine output and renal laboratory values for signs of nephrotoxicity. B: Check the specific gravity of the urine daily. C: Eliminate potassium-rich foods from the diet. D: Encourage the patient to void every 4 hours
A: Because the kidneys excrete most drugs, patients with renal failure may need a lower dosage of furosemide (Lasix) to prevent further damage to the kidneys. Options B, C, and D are incorrect. Urine specific gravity will not adequately assess renal status and may be altered by the diuresis secondary to the furosemide. Potassium should be increased when furosemide, a potent loop diuretic, is ordered and not eliminated. If diuresis is occurring, the patient may need to void more often than every 4 hours.
A male, age 67, reports taking diphenhydramine (Benadryl) for hay fever. Considering this patient's age, the nurse assesses for which of the following findings? A: A history of prostatic or urinary conditions B: Any recent weight gain C: A history of allergic reactions D: A history of peptic ulcer disease
A: Diphenhydramine (Benadryl) and other anithistamines are contraindicated in patients with BPH or lower urinary tract obstruction because anticholinergic effects may worsen these conditions. Options B, C, and D are incorrect. Diphenhydramine (Benadryl) is a common treatment for allergic conditions and has no effects on weight gain or peptic ulcer disease.
The nurse evaluates the patient's understanding of the procedure for application of triamcinolone (Kenalog, Aristocort) cream for acute contact dermatitis of the neck, secondary to a reaction to perfume. The patient asks why she can't just use up some fluocinonide (Lidex) cream she has left over from a poison ivy dermatitis last month. The nurse's response will be based on which of the following? A: High-potency corticosteroid creams should be avoided on the neck or face because of the possibility of additional adverse effects. B: All creams should be discarded after the initial condition has resolved. C: Fluocinonide cream is too low potency to use for contact dermatitis. D: Contact dermatitis from perfume is harder to treat than poison ivy dermatitis.
A: High-potency corticosteroid creams such as fluocinonide (Lidex) should be avoided in the highly vascular neck and facial areas because of the possibility of adverse effects. Options B, C, and D are incorrect. Topical corticosteroid creams may be kept at room temperature until the expiration date unless there are signs of discoloration of the cream, unless otherwise stated on the label, or as instructed by the health care provider. Fluocinonide is one of the higher-potency creams available for topical use. Contact dermatitis is a skin reaction to touching antigenic material, and the body's reaction depends on the antigen-antibody response not necessarily to the antigen itself.
The patient has been prescribed oxymetazoline (Afrin) nasal spray for seasonal rhinitis. The nurse will provide which of the following instructions? A: Limit use of this spray to 5 days or less. B: The drug may be sedating so be cautious with activities requiring alertness. C: This drug should not be used in conjunction with antihistamines. D: This is an over-the-counter drug and may be used as needed for congestion.
A: Prolonged use of oxymetazoline (Afrin) causes hypersecretion of mucus and worsening nasal congestion, resulting in increased daily use. Options B, C, and D are incorrect. This medication should not be used for longer than 5 days unless otherwise directed. It may be used with antihistamines for symptomatic relief and it is not sedating.

ANS: A Tenecteplase [TNKase] is given by bolus injection. Tissue plasminogen activator (tPA) must be infused over 90 minutes. Because tenecteplase [TNKase] is given by bolus injection, an infusion pump is not required. Although the patient should be monitored, tenecteplase [TNKase] does not require a prolonged infusion time.
A patient with atrial fibrillation is receiving warfarin [Coumadin]. The nurse notes that the patient's INR is 2.7. Before giving the next dose of warfarin, the nurse will notify the provider and: a. administer the dose as ordered. b. request an order to decrease the dose. c. request an order to give vitamin K (phytonadione). d. request an order to increase the dose.
ANS: A This patient has an INR in the appropriate range, which is 2 to 3 for most patients and 2.5 to 3.5 for some, so no change in warfarin dosing is necessary. It is not correct to request an order to either decrease or increase the dose of warfarin. It is not necessary to give vitamin K, which is an antidote for warfarin toxicity.
A patient who is taking warfarin [Coumadin] has just vomited blood. The nurse notifies the provider, who orders lab work revealing a PT of 42 seconds and an INR of 3.5. The nurse will expect to administer: a. phytonadione (vitamin K1) 1 mg IV over 1 hour. b. phytonadione (vitamin K1) 2.5 mg PO. c. protamine sulfate 20 mg PO. d. protamine sulfate 20 mg slow IV push.
ANS: A Vitamin K1 is given for warfarin overdose and may be given IV in an emergency. To reduce the incidence of an anaphylactoid reaction, it should be infused slowly. In a nonemergency situation, it would be appropriate to give vitamin K1 orally. Protamine sulfate is used for heparin overdose.
A patient is admitted to the hospital with unstable angina and will undergo a percutaneous coronary intervention. Which drug regimen will the nurse expect to administer to prevent thrombosis in this patient? a. Aspirin, clopidogrel, omeprazole b. Aspirin, heparin, abciximab [ReoPro] c. Enoxaparin [Lovenox], prasugrel [Effient], warfarin [Coumadin] d. Heparin, alteplase, abciximab [ReoPro]
ANS: B Abciximab, combined with ASA and heparin, is approved for IV therapy for patients undergoing PCI.
A patient who has taken warfarin [Coumadin] for a year begins taking carbamazepine. The nurse will anticipate an order to: a. decrease the dose of carbamazepine. b. increase the dose of warfarin. c. perform more frequent aPTT monitoring. d. provide extra dietary vitamin K.
ANS: B Carbamazepine is a powerful inducer of hepatic drug-metabolizing enzymes and can accelerate warfarin degradation. The warfarin dose should be increased if the patient begins taking carbamazepine. Decreasing the dose of carbamazepine is not indicated. It is not necessary to perform more frequent aPTT monitoring or to add extra vitamin K.
A patient will begin taking dabigatran etexilate [Pradaxa] to prevent stroke. The nurse will include which statement when teaching this patient? a. Dabigatran should be taken on an empty stomach to improve absorption. b. It is important not to crush, chew, or open capsules of dabigatran. c. The risk of bleeding with dabigatran is less than that with warfarin [Coumadin]. d. To remember to take dabigatran twice daily, a pill organizer can be useful.
ANS: B Patients should be taught to swallow capsules of dabigatran intact; absorption may be increased as much as 75%, increasing the risk of bleeding, if the capsules are crushed, chewed, or opened. Dabigatran may be taken with or without food. The risk of bleeding is not less than that of warfarin. Dabigatran is unstable when exposed to moisture, so using a pill organizer is not recommended.
A postoperative patient will begin anticoagulant therapy with rivaroxaban [Xarelto] after knee replacement surgery. The nurse performs a history and learns that the patient is taking erythromycin. The patient's creatinine clearance is 50 mL/min. The nurse will: a. administer the first dose of rivaroxaban as ordered. b. notify the provider to discuss changing the patient's antibiotic. c. request an order for a different anticoagulant medication. d. request an order to increase the dose of rivaroxaban.
ANS: B Patients with impaired renal function who are taking macrolide antibiotics will experience increased levels of rivaroxaban, increasing the risk of bleeding. It is correct to discuss using a different antibiotic if possible. The nurse should not administer the dose without discussing the situation with the provider. The patient's renal impairment is minor; if it were more severe, using a different anticoagulant might be appropriate. It is not correct to increase the dose of rivaroxaban.
A nurse caring for a patient receiving heparin therapy notes that the patient has a heart rate of 98 beats per minute and a blood pressure of 110/72 mm Hg. The patient's fingertips are purplish in color. A stat CBC shows a platelet count of less than 100,000 mm3. The nurse will: a. administer oxygen and notify the provider. b. discontinue the heparin and notify the provider. c. request an order for protamine sulfate. d. request an order for vitamin K (phytonadione).
ANS: B This patient is showing signs of heparin-induced thrombocytopenia, so the heparin should be discontinued immediately and the provider should be notified. The purplish color of the fingertips is caused by thrombosis, not hypoxia, so oxygen is not indicated. This patient may need continued anticoagulation therapy, so a request for protamine sulfate is not correct. Heparin is not a vitamin K inhibitor.
A patient is admitted to the emergency department with chest pain. An electrocardiogram shows changes consistent with an evolving myocardial infarction. The patient's cardiac enzymes are pending. The nurse caring for this patient will expect to: a. administer aspirin when cardiac enzymes are completed. b. give alteplase [Activase] within 2 hours. c. give tenecteplase [TNKase] immediately. d. obtain an order for an INR.
ANS: B When alteplase is given within 2 hours after symptom onset, the death rate for MI has been shown to be 5.4%, compared with 9.4% if given 4 to 6 hours after symptom onset. ASA may be given at the first sign of MI; it is not necessary to wait for cardiac enzyme results. Tenecteplase may be given more than 2 hours after onset of symptoms. Obtaining an order for an INR is not indicated.
A patient who has been taking warfarin is admitted with coffee-ground emesis. What can the nurse anticipate being prescribed for this patient? A) Vitamin E. B) Vitamin K. C) Protamine sulfate. D) Calcium gluconate.
Answer: B. Vitamin K is the antagonist for warfarin.
A postoperative patient reports pain in the left lower extremity. The nurse notes swelling in the lower leg, which feels warm to the touch. The nurse will anticipate giving which medication? a. Aspirin b. Clopidogrel [Plavix] c. Enoxaparin [Lovenox] d. Warfarin [Coumadin]
ANS: C Enoxaparin is a low-molecular-weight heparin and is used in situations requiring rapid onset of anticoagulant effects, such as massive DVT. Aspirin, clopidogrel, and warfarin are useful for primary prevention but are not used when rapid anticoagulation is required.
A patient has been receiving heparin while in the hospital to treat deep vein thromboses and will be discharged home with a prescription for enoxaparin [Lovenox]. The nurse provides teaching for the nursing student who asks about the advantages of enoxaparin over heparin. Which statement by the student indicates a need for further teaching? a. "Enoxaparin does not require coagulation monitoring." b. "Enoxaparin has greater bioavailability than heparin." c. "Enoxaparin is more cost-effective than heparin." d. "Enoxaparin may be given using a fixed dosage."
ANS: C Low-molecular-weight (LMW) heparins have higher bioavailability and longer half-lives, so routine coagulation monitoring is not necessary and fixed dosing is possible. LMW heparins are more expensive, however, so this statement indicates a need for further teaching.
A patient who is taking clopidogrel [Plavix] calls the nurse to report black, tarry stools and coffee-ground emesis. The nurse will tell the patient to: a. ask the provider about using aspirin instead of clopidogrel. b. consume a diet high in vitamin K. c. continue taking the clopidogrel until talking to the provider. d. stop taking the clopidogrel immediately.
ANS: C Patients who experience bleeding should be warned not to stop taking the clopidogrel until the prescriber says they should, since abrupt withdrawal may precipitate a thrombotic event. Taking aspirin with an active GI bleed is contraindicated. Warfarin is a vitamin K inhibitor; consuming extra vitamin K will not reverse the effects of clopidogrel.
A nursing student who is preparing to care for a postoperative patient with deep vein thrombosis asks the nurse why the patient must take heparin rather than warfarin. Which response by the nurse is correct? a. "Heparin has a longer half-life." b. "Heparin has fewer adverse effects." c. "The onset of warfarin is delayed." d. "Warfarin prevents platelet aggregation."
ANS: C Warfarin is not useful for treating existing thromboses or for emergencies because the onset of action is delayed. Heparin has a shorter half-life and has more side effects. Warfarin does not prevent platelet aggregation.
A 50-year-old female patient asks a nurse about taking aspirin to prevent heart disease. The patient does not have a history of myocardial infarction. Her cholesterol and blood pressure are normal, and she does not smoke. What will the nurse tell the patient? a. Aspirin is useful only for preventing a second myocardial infarction. b. She should ask her provider about using a P2Y12 ADP receptor antagonist. c. She should take one 81-mg tablet per day to prevent myocardial infarction. d. There is most likely no protective benefit for patients her age.
ANS: D ASA is used for primary prevention of myocardial infarction (MI) in men and in women older than 65 years. Aspirin for primary prevention may be used in women ages 55 to 79 years when the potential benefit of a reduction in MI outweighs the potential harm of increased GI hemorrhage. This patient has no previous history of MI, so the use of ASA is not indicated. ASA is useful for primary prevention, but only when indicated by cardiovascular risk, based on age, gender, cholesterol levels, blood pressure, and smoking status. A P2Y12 ADP receptor antagonist is used as secondary prevention. This patient should not begin taking ASA unless her risk factors change, or until she is 65 years old.
A patient is receiving heparin postoperatively to prevent deep vein thrombosis. The nurse notes that the patient has a blood pressure of 90/50 mm Hg and a heart rate of 98 beats per minute. The patient's most recent aPTT is greater than 90 seconds. The patient reports lumbar pain. The nurse will request an order for: a. a repeat aPTT to be drawn immediately. b. analgesic medication. c. changing heparin to aspirin. d. protamine sulfate.
ANS: D Heparin overdose may cause hemorrhage, which can be characterized by low blood pressure, tachycardia, and lumbar pain. Protamine sulfate should be given, and the heparin should be discontinued. An aPTT may be drawn later to monitor the effectiveness of protamine sulfate. Analgesics are not indicated because the lumbar pain is likely caused by adrenal hemorrhage. Aspirin will only increase the risk of hemorrhage.
A patient who takes warfarin [Coumadin] is brought to the emergency department after accidentally taking too much warfarin. The patient's heart rate is 78 beats per minute and the blood pressure is 120/80 mm Hg. A dipstick urinalysis is normal. The patient does not have any obvious hematoma or petechiae and does not complain of pain. The nurse will anticipate an order for: a. vitamin K (phytonadione). b. protamine sulfate. c. a PTT. d. a PT and an INR.
ANS: D This patient does not exhibit any signs of bleeding from a warfarin overdose. The vital signs are stable, there are no hematomas or petechiae, and the patient does not have pain. A PT and INR should be drawn to evaluate the anticoagulant effects. Vitamin K may be given if laboratory values indicate overdose. Protamine sulfate is given for heparin overdose. PTT evaluation is used to monitor heparin therapy.
A patient who takes warfarin for atrial fibrillation undergoes hip replacement surgery. On the second postoperative day, the nurse assesses the patient and notes an oxygen saturation of 83%, pleuritic chest pain, shortness of breath, and hemoptysis. The nurse will contact the provider to report possible ____ and request an order for ____. a. congestive heart failure; furosemide [Lasix] b. hemorrhage; vitamin K (phytonadione) c. myocardial infarction; tissue plasminogen activator (tPA) d. pulmonary embolism; heparin
ANS: D This patient is exhibiting signs of pulmonary embolism. Heparin is used when rapid onset of anticoagulants is needed, as with pulmonary embolism. The patient would have respiratory cracks and a cough with congestive heart failure. Hemorrhage involves a decrease in blood pressure, bruising, and lumbar pain. The patient has pleuritic pain, which is not consistent with the chest pain of a myocardial infarction.
A patient has been taking warfarin [Coumadin] for atrial fibrillation. The provider has ordered dabigatran etexilate [Pradaxa] to replace the warfarin. The nurse teaches the patient about the change in drug regimen. Which statement by the patient indicates understanding of the teaching? a. "I may need to adjust the dose of dabigatran after weaning off the warfarin." b. "I should continue to take the warfarin after beginning the dabigatran until my INR is greater than 3." c. "I should stop taking the warfarin 3 days before starting the dabigatran." d. "I will stop taking the warfarin and will start taking the dabigatran when my INR is less than 2."
ANS: D When switching from warfarin to dabigatran, patients should stop taking the warfarin and begin taking the dabigatran when the INR is less than 2. It is not correct to begin taking the dabigatran before stopping the warfarin. While warfarin is stopped before beginning the dabigatran, the decision to start taking the dabigatran is based on the patient's INR and not on the amount of time that has elapsed.
seizures
Abnormal electrical activity in the brain
A patient is prescribed enoxaparin. The nurse knows that low-molecular-weight heparin has what kind of half-life? A) A longer half-life than heparin B) A shorter half-life than heparin C) The same half-life as heparin D) A four-times shorter half-life than heparin
Answer: A.
A client is admitted to the acute psychiatric care unit after 2 weeks of increasingly erratic behavior. The client has been sleeping poorly, has lost 8 lb (3.6 kg), is poorly groomed, exhibits hyperactivity, and loudly denies the need for hospitalization. Which nursing intervention takes priority for this client?
Administering a sedative as prescribed
Atypical Antidepressants (Bupropion, Wellbutrin)
Affects the activity of norepinephrine and dopamine, inhibits serotonin reuptake Contraindicated in patients with seizure disorders (lowers threshold) Marketed as Zyban for smoking cessation
A patient complains of a sore throat and has been told it is due to beta-hemolytic streptococcal infection. The nurse anticipates that the patient has which acute condition? A) Rhinitis B) Sinusitis C) Pharyngitis D) Rhinorrhea
Answer: C.
Temporary coverage grafting
Allograft (cadaver skin) Xenograft (biological dressing usually pigskin)
The nurse is providing discharge teaching to the client with heart failure, focusing on when to seek medical attention. Which statement by the client indicates understanding of the teaching? a. "I will call the provider if I have a cough lasting 3 or more days." b. "I will report to the provider weight loss of 2 to 3 pounds in a day." c. "I will try walking for 1 hour each day." d. "I should expect occasional chest pain."
Answer: "I will call the provider if I have a cough lasting 3 or more days." Rationale: Cough, a symptom of heart failure, is indicative of intra-alveolar edema; the provider should be notified.
The client, a college athlete who has collapsed during soccer practice, has been diagnosed with hypertrophic cardiomyopathy. The client says, "This can't be. I am in great shape. I eat right and exercise." What is the nurse's best response? a. "How does this make you feel?" b. "This can be caused by taking performance-enhancing drugs." c. "This may be caused by a genetic trait." d. "Just imagine how bad it would be if you weren't in good shape."
Answer: "This may be caused by a genetic trait." Rationale: Hypertrophic cardiomyopathy is often transmitted as a single-gene autosomal dominant trait.
A child is ordered to receive naloxone intravenously STAT. The child's weight is 20 kg, and the recommended child's dosage is 0.01 mg/kg. Naloxone is available in a 400 mcg/mL solution. How much drug will the nurse plan to administer?
Answer: 0.5 mL.
A client rates anxiety at 8 out of 10 on a scale of 1 to 10, is restless, and has narrowed perceptions. Which of the following medications would appropriately be prescribed to address these symptoms? Select all that apply. 1. Chlordiazepoxide (Librium). 2. Clonazepam (Klonopin). 3. Lithium carbonate (lithium). 4. Clozapine (Clozaril). 5. Oxazepam (Serax).
An anxiety rating of 8 out of 10, restlessness, and narrowed perceptions all are symptoms of increased levels of anxiety. 1. Chlordiazepoxide (Librium) is a benzodiazepine. Benzodiazepines are classified as antianxiety medications and would be appropriately prescribed to address signs and symptoms of anxiety. 2. Clonazepam (Klonopin) is a benzodiazepine. Benzodiazepines are classified as antianxiety medications and would be appropriately prescribed to address signs and symptoms of anxiety. 5. Oxazepam (Serax) is a benzodiazepine. Benzodiazepines are classified as antianxiety medications and would be appropriately prescribed to address signs and symptoms of anxiety. TEST-TAKING HINT: The test taker first must recognize the signs and symptoms presented in the question as an indication of increased levels of anxiety. Next, the test taker must recognize the medications that address these symptoms. Also, it is common to confuse lithium carbonate (lithium) and Librium and clozapine and clonazepam. To answer this question correctly, the test taker needs to distinguish between medications that are similar in spelling.
You are caring for a patient admitted with chronic obstructive pulmonary disease. During your shift assessment, you find that your patient is experiencing a change in his respiratory and mental status. You are aware that the most accurate measurement of the concentration of oxygen in the patient's blood is what?
An arterial blood gas study
What provisions of the Dietary Supplement Health and Education Act of 1994 are most important for the nurse to know related to patient health teaching? (Select all that apply.) A) Clarified marketing regulations B) Reclassified herbs as dietary supplements C) Stated that herbal products can be marketed with suggested dosages D) Required that package labels give quality and strength of all contents E) Stated that herbs can be used as drugs
Answer: A, B, C
A patient hospitalized with a fractured femur following an automobile accident develops nausea and vomiting, abdominal cramps, and restlessness. The nurse suspects that the patient is experiencing which reaction? A) Opioid withdrawal B) Alcohol toxicity C) Flashbacks from LSD use D) Nicotine withdrawal
Answer: A.
An overuse or ineffective use of ego defense mechanisms, which results in a maladaptive response to anxiety, is an example of the ___________________ theory of generalized anxiety disorder development.
An overuse or ineffective use of ego defense mechanisms, which results in a maladaptiveresponse to anxiety, is an example of thepsychodynamic theory of generalized anxiety disorder development. TEST-TAKING HINT: To answer this question correctly, the test taker should review the various theories related to the development of generalized anxiety disorder.
The nurse caring for a client discusses the importance of restricting sodium in the diet. Which statement made by the client indicates that he needs further teaching? a. "I should avoid grilling hamburgers." b. "I must cut out bacon and canned foods." c. "I shouldn't put the salt shaker on the table anymore." d. "I should avoid lunch meats but may cook my own turkey."
Answer: "I should avoid grilling hamburgers." Rationale: Cutting out beef or hamburgers made at home is not necessary; however, fast food hamburgers are to be avoided owing to higher sodium content.
Which of the following actions by the nurse is the most important when caring for a client with renal disease who has an order for furosemide (Lasix)? 1. Assess urine output and renal laboratory values for signs of nephrotoxicity. 2. Check the specific gravity of the urine daily. 3. Eliminate potassium- rich foods from the diet. 4. Encourage the client to void every 4 hours.
Answer: 1 Rationale: Because the kidneys excrete most drugs, clients with renal failure may need a lower dosage of furosemide (Lasix) to prevent further damage to the kidneys. Options 2,3 and 4 are incorrect. Urine specific gravity will not adequately assess renal status and may be altered by the diuresis secondary to the furosemide. Potassium should be increased when furosemide, a potent loop diuretic, is ordered and not eliminated. If diuresis is occurring, the patient may need to void more often then every 4 hours.
39.6 The nurse teaches the client about the use of a metered-dose inhaler (MDI). The nurse evaluates that additional teaching is required when the client makes which statement? 1. "I should hear a whistling sound each time I use the metered-dose inhaler (MDI)." 2. "I need to rinse my mouth each time after using the metered-dose inhaler (MDI)." 3. "I need to drink a lot of fluids while I am using the metered-dose inhaler (MDI)." 4. "I need to follow the instructions about using the metered-dose inhaler (MDI)."
Answer: 1 "I should hear a whistling sound each time I use the metered-dose inhaler (MDI)." Rationale: A whistling sound indicates that the metered-dose inhaler (MDI) is not being used effectively and the client is not receiving the medication. Rinsing the mouth after using the metered-dose inhaler (MDI) is correct; it will help reduce oral absorption of the drug. Fluids are encouraged to liquefy pulmonary secretions when using the metered-dose inhaler (MDI). Following instructions indicates compliance with use of the metered-dose inhaler (MDI).
38.10 The client receives beclomethasone (Beconase) intranasally as treatment for allergic rhinitis. He asks the nurse if this drug is safe because it is a glucocorticoid. What is the best response by the nurse? 1. "Intranasal glucocorticoids produce almost no serious adverse effects." 2. "Intranasal glucocorticoids are safe if they are not used too long." 3. "Intranasal glucocorticoids are safe if you do not swallow too much while using them." 4. "Intranasal glucocorticoids are safe only if used once a day."
Answer: 1 "Intranasal glucocorticoids produce almost no serious adverse effects." Rationale: Intranasal glucocorticoids produce almost no serious adverse effects. There is no time frame for the use of intranasal glucocorticoids, they produce almost no serious adverse effects. There is no problem with swallowing intranasal glucocorticoids, they produce almost no serious adverse effects. Intranasal glucocorticoids may be used more than once a day; they produce almost no serious adverse effects.
39.2 The nurse teaches a medication class on bronchodilators for clients with asthma. The nurse evaluates that learning has occurred when the clients make which statement? 1. "The medication widens our airways because it stimulates the fight-or-flight response of our nervous system." 2. "The medication widens our airways because it acts on the parasympathetic nervous system." 3. "The medication widens our airways because it decreases the production of mucous that narrows our airways." 4. "The medication widens our airways because it decreases the production of histamine that narrows our airways."
Answer: 1 "The medication widens our airways because it stimulates the fight-or-flight response of our nervous system." Rationale: During the fight-or-flight response, beta2-adrenergic receptors of the sympathetic nervous system are stimulated, the bronchiolar smooth muscle relaxes, and bronchodilation occurs. Bronchodilators act on the sympathetic nervous system, not the parasympathetic nervous system. Bronchodilators do not decrease the production of mucous. Bronchodilators do not decrease the production of histamine.
38.14 The client is very frustrated that pseudoephedrine is no longer stocked on pharmacy shelves. The client does not like to go the pharmacy counter to obtain the drug. What is the best response by the nurse? 1. "This is frustrating, but hopefully it will decrease the amount of methamphetamine being produced." 2. "This is frustrating, but hopefully it will decrease the amount of crack cocaine being produced." 3. "This is frustrating, but hopefully it will decrease the amount of inhaled heroin being produced." 4. "This is frustrating, but hopefully it will decrease the amount of methylphenidate being produced."
Answer: 1 "This is frustrating, but hopefully it will decrease the amount of methamphetamine being produced." Rationale: Pseudoephedrine (Sudafed) is a major ingredient in the production of methamphetamine. Pseudoephedrine (Sudafed) is a major ingredient in the production of methamphetamine, not crack cocaine. Pseudoephedrine (Sudafed) is a major ingredient in the production of methamphetamine, not heroin. Pseudoephedrine (Sudafed) is a major ingredient in the production of methamphetamine, not methylphenidate. Implementation
39.11 The client receives zafirlukast (Accolate) as treatment for asthma. The nurse has completed medication education and evaluates learning has occurred when the client makes which statement? 1. "This medication decreases the inflammation in my lungs." 2. "This medication dilates my airways so I can breathe better." 3. "This medication is good when I have an acute attack of asthma." 4. "This medication activates my fight-or-flight response."
Answer: 1 "This medication decreases the inflammation in my lungs." Rationale: Zafirlukast (Accolate) prevents airway edema and inflammation by blocking leukotriene receptors in the airways. Zafirlukast (Accolate) is not a bronchodilator. Zafirlukast (Accolate) is ineffective for acute asthma attacks. Zafirlukast (Accolate) is not a beta-adrenergic drug so it does not activate the sympathetic (fight-or-flight) nervous system.
38.3 Which assessment finding, by the nurse, is a priority concern when a client receives pseudoephedrine (Sudafed) 60 mg PO every 4 hours? 1.Blood pressure of 150/60 mmHg 2.Temperature of 100° F 3.Complaints of a dry mouth 4.Respiratory rate of 22
Answer: 1 Blood pressure of 150/60 mmHg Rationale: Psuedoephedrine (Sudafed) is a vasoconstrictor and can increase blood pressure. A temperature is possible with pseudoephedrine (Sudafed), but is not the primary concern. A dry mouth is possible with pseudoephedrine (Sudafed), but is not the primary concern. A respiratory rate of 22 is possible with pseudoephedrine (Sudafed), but is not the primary concern.
38.6 The nursing instructor teaches the nursing students about the major functions of the upper respiratory tract. What will the best plan of the nursing instructor include? Select all that apply. 1. The nasal mucosa is the first line of immunological defense. 2. The nose warms the air before it reaches the lungs. 3. Activation of the sympathetic nervous system constricts arterioles in the nose. 4. Activation of the parasympathetic nervous system constricts arterioles in the nose. 5. Inward airflow from the trachea branches off to the two bronchi.
Answer: 1, 2, 3 Rationale: The nasal mucosa is the first line of immunological defense. The nose warms the air before it reaches the lungs. Activation of the sympathetic nervous system constricts arterioles in the nose. Activation of the sympathetic nervous system, not the parasympathetic nervous system, constricts arterioles in the nose. The trachea and bronchi are part of the lower respiratory tract.
38.7 The client has allergic rhinitis and asks the nurse what causes this. What is the best response by the nurse? Select all that apply. 1. "It is caused by weeds and grasses." 2. "It is caused by tobacco smoke." 3. "You inherited the predisposition for this." 4. "It is caused by animals." 5. "It is caused by asthma."
Answer: 1, 2, 3, 4 Rationale: Allergic rhinitis is caused by weeds and grasses. Allergic rhinitis is caused by tobacco smoke. Allergic rhinitis is caused by animals. There is a strong genetic predisposition for allergic rhinitis. Although associated with asthma, allergic rhinitis is not caused by asthma.
39.7 The client receives beclomethasone (Beconase). What will the best assessment of the nurse include? Select all that apply. 1. Assess if the client alternates nares with administration of nasal spray. 2. Assess the client's blood glucose prior to administration of nasal spray. 3. Assess the client's mouth for any sign of fungal infection. 4. Assess the client for any hoarseness or change in voice. 5. Assess if the client has blown his nose prior to administration of nasal spray.
Answer: 1, 3, 4, 5 Rationale: Nares should be alternated with nasal spray. Clients may develop candidiasis so the mouth should be assessed. Clients may experience a change in voice as a local effect. The client should gently blow the nose prior to use to clear the nasal passages. There is no need to assess the client's blood glucose.
The nurse is providing teaching to a client who has been prescribed furosemide (Lasix). Which of the following should the nurse teach the client? 1. Avoid consuming large amounts of kale, cauliflower, or cabbage. 2. Rise slowly from a lying or sitting position. 3. Count the pulse for one full minute before taking this medication. 4. Restrict fluid intake to no more than 1L per 24 hour period.
Answer: 2 Rationale: Loop diuretics such as furosemide (Lasix) may dramatically reduce a client's circulating blood volume from diuresis and may cause orthostatic hypotension. To minimize the chance for syncope and falls, the client should be taught to rise slowly from a lying or sitting position to standing. Options 1,3, and 4 are incorrect. Kale, cauliflower and cabbage contain vitamin K, which does not need to be restricted during diuretic therapy. Monitoring the pulse along with blood pressure to assess for tachycardia is advised, but the pulse does not need to be taken for 1 full minute before taking the drug. Fluids should not be restricted during diuretic therapy unless ordered by the provider.
38.4 The elderly client receives diphenhydramine (Benadryl) for allergies. The nurse completes medication education and evaluates learning has occurred when the client makes which statement? 1. "If my nose begins to run, I can use a nasal spray." 2. "Constipation is common; I need to increase fiber in my diet." 3. "I need to watch my intake of sodium with this medication." 4. "I cannot take this medication with pseudoephedrine (Sudafed)."
Answer: 2 "Constipation is common; I need to increase fiber in my diet." Rationale: Constipation is a common side effect of antihistamines. Antihistamines dry, not increase, secretions. Sodium intake is not related to antihistamines. Pseudoephedrine (Sudafed) is commonly used with antihistamines.
39.10 The physician has ordered ipratropium (Atrovent) for the client. What is a priority assessment question for the nurse to ask prior to administering this medication? 1. "Do you have diabetes mellitus?" 2. "Do you have glaucoma?" 3. "Do you have seizures?" 4. "Have you ever had a heart attack?"
Answer: 2 "Do you have glaucoma?" Rationale: Anticholinergic drugs can worsen narrow angle glaucoma. Anticholinergic drugs do not impact glucose levels, so having diabetes mellitus is not a concern. Anticholinergic drugs do not affect seizure disorders, this is not a concern. Anticholinergic drugs do not affect cardiac status; a prior heart attack is not a concern.
38.8 The nursing instructor teaches the student nurses about histamine receptors and evaluates that further instruction is needed when the students make which statement? 1. "H1-receptors are responsible for allergic symptoms." 2. "H1-receptors are responsible for peptic ulcers." 3. "H2-receptors are responsible for peptic ulcers." 4. "H2-receptors increase mucus secretion in the stomach."
Answer: 2 "H1-receptors are responsible for peptic ulcers." Rationale: H2-receptors, not H1-receptors, are responsible for peptic ulcers. H1-receptors are responsible for allergic symptoms. H2-receptors are responsible for peptic ulcers. H2-receptors increase mucus secretion in the stomach.
38.2 The client tells the nurse that her symptoms have become worse since she has been using oxymetazoline (Afrin) for nasal congestion. What is the best assessment question for the nurse to ask? 1. "Can you describe how your symptoms have gotten worse?" 2. "How long have you been using the medication?" 3. "May I take your temperature?" 4. "Are you using any other inhaled medications?"
Answer: 2 "How long have you been using the medication?" Rationale: Oxymetazoline (Afrin) can cause rebound congestion if used for too long, so length of treatment is the best assessment question. The problem is rebound congestion, asking the client to describe her symptoms is unnecessary. The problem is rebound congestion, not infection; taking the client's temperature is not necessary. The use of other inhaled medications will not cause or prevent rebound congestion, so this question is unnecessary.
A patient is placed on heparin, and the nurse acknowledges that heparin is effective for preventing clot formation in patients who have which disorder(s)? (Select all that apply.) A) Coronary thrombosis B) Acute myocardial infarction C) Deep vein thrombosis D) Hemorrhagic stroke E) Disseminated intravascular coagulation
Answer: A, B, C, D, E
A patient's blood pressure is 130/84. The health care provider plans to suggest nonpharmacologic methods to lower blood pressure. Which should the nurse include in teaching? (Select all that apply.) A) Stress-reduction techniques B) An exercise program C) Salt restriction D) Smoking cessation E) A diet with increased protein
Answer: A, B, C, D.
38.12 The mother asks the nurse when she should give her child cough medicine. What is the best response by the nurse? 1. "When he has bronchitis." 2. "When he has a dry cough and cannot rest." 3. "When he is coughing up green secretions." 4. "When he has a temperature over 102°F."
Answer: 2 "When he has a dry cough and cannot rest." Rationale: Dry, hacking, and nonproductive cough is irritating to the membranes of the throat and deprives the client of much needed rest, so a cough medicine would be warranted in this case. It is not desirable to suppress the cough reflex in a client with bronchitis; the child should not receive cough medicine. If the client is coughing up green secretions, he needs to receive an antibiotic, not cough medicine. If a client is febrile, he needs an assessment prior to receiving cough medication.
39.15 The client receives ipratropium (Atrovent). She tells the nurse she is going to stop it because of the bitter taste in her mouth after using the medication. What is the best response of the nurse? 1. "That is a good idea; you are experiencing a serious side effect." 2. "You can decrease that side effect by rinsing your mouth after use." 3. "That is a common side effect; it will go away in time." 4. "Are you sure you are using the medication properly?"
Answer: 2 "You can decrease that side effect by rinsing your mouth after use." Rationale: Ipratropium (Atrovent) produces a bitter taste, which may be relieved by rinsing the mouth after use. The client is not experiencing a serious side effect; there is no need to stop the medication. The bitter taste will not go away in time; the client must rinse her mouth. Asking how the client uses the medication may be a good option, but not with the common side effect of bitter taste.
39.4 The nurse plans to teach an adolescent about inhalation therapy as part of the treatment plan for the client's asthma. What does the best plan of the nurse include? 1. Inhalation therapy is effective because it provides around-the-clock therapy, as opposed to oral medications. 2. Inhalation therapy is effective because it goes to the direct site of action in the respiratory tract. 3. Inhalation therapy is effective because it provides systemic relief of symptoms as well as local relief. 4. Inhalation therapy is the preferred treatment for adolescents because it is easier for them to manage.
Answer: 2 Inhalation therapy is effective because it goes to the direct site of action in the respiratory tract. Rationale: The major advantage of aerosol therapy is that it delivers the drugs to their direct site of action. Inhalation therapy does not provide around-the-clock therapy. Inhalation therapy does not provide systemic relief of symptoms. Inhalation therapy is used for adolescents because it is effective, not because it is easier for them to manage.
38.15 The client takes diphenhydramine (Benadryl), but forgets to tell the physician about this drug when a monoamine oxidase inhibitor (MAOI) drug is prescribed for depression. What will the best assessment of the nurse reveal? 1. The depression will not subside. 2. The client may develop a hypertensive crisis. 3. The diphenhydramine (Benadryl) will not control allergies. 4. The client may develop seizures. Answer: 2 Rationale: The combination of diphenhydramine (Benadryl) and a monoamine oxidase inhibitor (MAOI) drug can result in a hypertensive crisis. Depression is not the concern with this combination, a hypertensive crisis is. Control of allergies is not the concern with this combination, a hypertensive crisis is. Seizures are not the concern with this combination, a hypertensive crisis is.
Answer: 2 The client may develop a hypertensive crisis. Rationale: The combination of diphenhydramine (Benadryl) and a monoamine oxidase inhibitor (MAOI) drug can result in a hypertensive crisis. Depression is not the concern with this combination, a hypertensive crisis is. Control of allergies is not the concern with this combination, a hypertensive crisis is. Seizures are not the concern with this combination, a hypertensive crisis is.
39.14 The nurse is preparing to administer beclomethasone (Beconase) to several clients. For which client would the nurse hold the drug and contact the physician? 1. The client who has diabetes mellitus. 2. The client who has methicillin resistant Staphylococcus aureus (MRSA). 3. The client who has had a myocardial infarction (MI). 4. The client who has terminal cancer.
Answer: 2 The client who has methicillin resistant Staphylococcus aureus (MRSA). Rationale: Glucocorticoids can mask the signs of infection, and are contraindicated if active infection is present. Beclomethasone (Beconase) is not contraindicated in clients who have diabetes mellitus. Beclomethasone (Beconase) is not contraindicated in clients who have had a myocardial infarction. Beclomethasone (Beconase) is not contraindicated in clients who have terminal cancer.
38.9 The client receives diphenhydramine (Benadryl) to control allergic symptoms. Which common symptom does the nurse teach the client to report to the physician? 1. Sedation 2. Urinary hesitancy 3. Diarrhea 4. Projectile vomiting
Answer: 2 Urinary hesitancy Rationale: Urinary hesitancy is an anticholinergic effect of diphenhydramine (Benadryl) and should be reported to the physician. Sedation is a common side effect, but does not need to be reported. Diarrhea is not a common side effect. Projectile vomiting is not a common side effect.
39.8 The client receives ipratropium (Atrovent) via inhalation for the treatment of chronic asthma. The nurse plans to do medication education with the client. What will the best plan of the nurse include? Select all that apply. 1. The medication may also be used for acute asthma attacks. 2. Report any changes in urinary pattern. 3. Wait 15 minutes before using any other inhaled medications. 4. Report a change in the color or amount of sputum. 5. Use the medication consistently, not occasionally.
Answer: 2, 4, 5 Rationale: Anticholinergic drugs can result in urinary retention, and the client should report any changes in urinary patterns. A side effect of anticholinergics is sinusitis and upper respiratory tract infection, so the client should report any change in the color or amount of sputum. To get the most benefit from ipratropium (Atrovent), it must be used consistently. Anticholinergic drugs will not terminate an acute asthma attack, as peak effects may take 1 to 2 hours. It is only necessary to wait 5 minutes, not 15 minutes, between inhaled medications.
Which of the following manifestations may indicate the the client taking metolazone (Zaroxolyn) is experiencing hypokalemia? 1. Hypertension 2. Polydipsia 3. Cardiac dysrhythmias 4. Skin rash
Answer: 3 Rationale: Metolazone (Zaroxolyn) is a thiazide diuretic and causes potassium loss. Signs of hypokalemia include cardiac dysrhythmias, hypotension, dizziness and fainting. Options 1,2 and 4 are incorrect. Polydipsia is not associated with hypokalemia. Hypertension is a clinical indication for the use for diuretics. Skin rashes are an adverse effect of metolazone but are not a symptom of hypokalemia.
While planning for a client's discharge from the hospital, which of the following teaching points would be included for a client going home with a prescription for chlorothiazide (Diuril)? 1. Increase fluid and salt intake to make up for the losses caused by the drug. 2. Increase intake of vitamin C- rich foods such as grapefruit and oranges. 3. Report muscle cramping or weakness to the health care provider. 4. Take the drug at night because it may cause drowsiness.
Answer: 3 Rationale: Muscle cramping or weakness may indicate hypokalemia and should be reported to the health care provider. Options 1,2, and 4 are incorrect. Clients on diuretic therapy are taught to monitor sodium (salt) and water intake to maintain adequate, but not excessive, amounts. Vitamin C -rich foods do not need to be increased while a client is taking chlorothiazide (Diuril). The drug should be taken early in the day to avoid nocturia. It does not cause drowsiness.
38.5 The nurse completes medication education for the client receiving antihistamines. The nurse evaluates learning has occurred when the client makes which statement? 1. "I can still have my after-dinner-drink." 2. "I need to increase fluids while taking this medication." 3. "This medication could make me very sleepy." 4. "This medication is safe because it is sold over-the-counter (OTC)."
Answer: 3 "This medication could make me very sleepy." Rationale: Sedation is a common side effect of antihistamines. Alcohol will increase the sedative effects of antihistamines, so the client should not drink while taking antihistamines. There is no need to increase fluids when taking antihistamines. Just because a medicine is sold over-the-counter (OTC), does not mean it is safe.
39.1 The client receives albuterol (Proventil) via inhaler. He asks the nurse why he can't just take a pill. What is the best response by the nurse? 1. "Because this medication cannot be absorbed from your GI tract; the acid in your stomach would destroy it." 2. "Because pills cannot help your illness; you must have inhaled medications for relief of symptoms." 3. "Because the surface of your lungs, and their blood supply, results in a rapid onset of action of the drug when inhaled. 4. Because pills would produce too many side effects; you will have very few side effects with inhaled medications.
Answer: 3 Because the surface of your lungs, and their blood supply, results in a rapid onset of action of the drug when inhaled. Rationale: The respiratory system offers a rapid and efficient mechanism for delivering drugs. The enormous surface area of the bronchioles and alveoli, and the rich blood supply to these areas, results in an almost instantaneous onset of action for inhaled substances. Albuterol (Proventil) can be given orally (PO), but has a faster onset of action if inhaled. Oral medications are effective with some symptoms of respiratory disorders, but inhaled medications work faster. Inhaled medications also produce side effects.
39.5 A client receives theophylline (Theo-Dur) and calls the clinic to say he has had nausea and vomiting for two days. What is the best action by the nurse? 1. Recommend that the client begin a clear liquid diet. 2. Ask the client if he has been exposed to anyone with the flu. 3. Tell the client to come to the clinic for an assessment. 4. Ask the client if he has eaten at any unclean restaurants.
Answer: 3 Tell the client to come to the clinic for an assessment. Rationale: Nausea and vomiting are symptoms of theophylline toxicity; the client needs to come to the clinic for an assessment. A clear-liquid diet might help, but the client needs to be assessed for theophylline toxicity. Flu could be the cause of the client's symptoms, but he needs to be assessed for theophylline toxicity. Food poisoning could be the cause of the client's symptoms, but he needs to be assessed for theophylline toxicity.
39.12 The physician has prescribed cromolyn (Intal) for the client with asthma. The nurse plans to do medication education. What will the best plan of the nurse include? 1. This medication can affect blood glucose levels. 2. This medication is indicated for acute asthma attacks. 3. This medication will help prevent asthma attacks. 4. This medication can result in hypertension.
Answer: 3 This medication will help prevent asthma attacks. Rationale: By reducing inflammation, cromolyn (Intal) is able to prevent asthma attacks. Cromolyn (Intal) does not affect blood glucose levels. Cromolyn (Intal) is ineffective for acute asthma attacks. Cromolyn (Intal) does not cause hypertension.
The client admitted for heart failure (HF) has been receiving hydrochlorothiazide (Microzide). Which of the following laboratory levels should the nurse carefully monitor? (Select all that apply) 1. Platelet count 2. WBC count 3. Potassium 4. Sodium 5. Uric acid
Answer: 3,4,5 Rationale: Thiazide diuretics such as hydrochlorothiazide (Microzide) cause loss of sodium and potassium but may cause hyperuricemia. Options 1 and 2 are incorrect. Hydrochlorothiazide does not have a direct effect on blood cells.
38.11 The nurse teaches the client about the difference between oral and nasal decongestants. The nurse evaluates learning has been effective when the client makes which statement? 1. "Oral and nasal decongestants can cause rebound congestion." 2. "Intranasal decongestants are safe to use for a month, if needed." 3. "Oral decongestants are the most effective at relieving severe congestion." 4. "Oral decongestants can cause hypertension."
Answer: 4 "Oral decongestants can cause hypertension." Rationale: One of the side effects of oral decongestants is hypertension. Oral decongestants do not cause rebound congestion, nasal decongestants can cause rebound congestion. Intranasal decongestants should not be used for longer than 3 to 5 days. Intranasal, not oral, decongestants are the most effective at relieving severe congestion.
39.13 The physician has ordered salmeterol (Serevent) for the client with asthma. The client asks the nurse how to use the medication. What is the best response by the nurse? 1. "Use it frequently because its action is very short." 2. "Use it when you have an acute asthma attack." 3. "Take it 5 to 10 minutes before you exercise." 4. "Take it 30 to 60 minutes before you exercise."
Answer: 4 "Take it 30 to 60 minutes before you exercise." Rationale: When taken 30 to 60 minutes prior to physical activity, salmeterol (Serevent) can prevent exercise-induced bronchospasm. Salmeterol (Serevent) has a 12-hour duration of action, not a short duration of action. Salmeterol (Serevent) takes 15 to 25 minutes to act so it cannot be used to terminate an acute asthma attack. Taking salmeterol (Serevent) 5 to 10 minutes prior to beginning exercise is not sufficient enough time to prevent an acute attack.
A patient has a low-density lipoprotein of 175 mg/dL and a high-density lipoprotein of 30 mg/dL. What teaching should the nurse implement for this patient? A) Discuss medications ordered, dietary changes, and exercise. B) No changes in lifestyle are needed; continue with the current plan. C) Discuss how to have fat intake be 40% of caloric intake. D) Begin keeping a food diary, and schedule lab work to be repeated in 6 months.
Answer: A.
39.3 The client asks the nurse why she must continue taking her asthma medication even though she has not had an asthma attack in several months. What is the best response by the nurse? 1. "The medication needs to be taken for at least a year; then, if you have not had an acute attack, you can stop it." 2. "The medication needs to be taken or your lungs will be severely damaged and we will not be able to stop an acute attack." 3. "The medication needs to be taken indefinitely according to your doctor, so you should discuss this with him." 4. "The medication is still needed to decrease inflammation in your airways and help prevent an attack."
Answer: 4 "The medication is still needed to decrease inflammation in your airways and help prevent an attack." Rationale: Effective treatment of asthma includes long-term treatment to prevent attacks and decrease inflammation, as well as short-term treatment when an attack occurs. Long-term treatment of asthma continues indefinitely, not for just one year. Telling a client that lungs will be severely damaged is nontherapeutic; the inability to prevent an acute attack in this client is not true. The nurse is able to answer the client's question; it does not need to be referred to the physician.
39.9 The client receives isoproterenol (Isuprel) via inhalation. The nurse determines that the client is experiencing a side effect of this medication when reviewing which laboratory test? 1. Creatinine of 1.0 mg/dl 2. Sodium of 160 3. AST of 20 units/L 4. Glucose of 145
Answer: 4 Glucose of 145 Rationale: A side effect of isoproterenol (Isuprel) is hyperglycemia. A creatinine of 1.0 mg/dl is a normal creatinine level, and isoproterenol (Isuprel) is not nephrotoxic. A sodium of 160 is an elevated sodium level, but isoproterenol (Isuprel) does not cause hypernatremia. An AST of 20 units/L is a normal AST, and isoproterenol (Isuprel) is not hepatotoxic.
38.13 The physician orders ipratropium bromide (Atrovent) for the client. The nurse would hold the drug and contact the physician with which assessment finding? 1. The client has hypertension. 2. The client is pregnant. 3. The client has diabetes mellitus. 4. The client has glaucoma.
Answer: 4 The client has glaucoma. Rationale: Ipratropium bromide (Atrovent) is an anticholinergic drug and should be used in caution with clients who have glaucoma. There is no contraindication with the use of ipratropium bromide (Atrovent) in clients who have hypertension. Ipratropium bromide (Atrovent) is Pregnancy Category B drug, and should be safe for use in the pregnant client. There is no contraindication with the use of ipratropium bromide (Atrovent) in a client with diabetes mellitus.
A child who weighs 88 pounds is ordered to receive 3 mg/kg of a drug. The drug is available in a 15 mg/mL elixir. How much drug will the patient receive?
Answer: 8 mL.
The nurse has been measuring the blood pressure of an African-American patient every 4 hours for the past 3 days in a hospital setting. The blood pressure is consistently above 140/90. The patient has been adherent to the antihypertensive drug therapy while hospitalized. The nurse will initially perform which action? A) Determine if the patient has been given high sodium foods from visitors. B) Withhold the antihypertensive drug until the physician can be notified. C) Increase blood pressure measurements to every 2 hours. D) Place the patient on a restricted fluid intake.
Answer: A
39.17 The nurse understands that one advantage of inhaled pulmonary drugs over oral drugs is that inhaled drugs: a. Allow for quick absorption. b. Increase adverse effects. c. Are delivered to systemic locations. d. Allow for convenience to the client.
Answer: A Allow for quick absorption. Rationale: A. Inhalation is the most common route of administration; it is rapid, and allows for quick absorption to direct airway. B. Inhaled drugs decrease adverse effects. C. Inhaled drugs are delivered to local sites. D. Inhaled drugs are not as convenient as oral.
39. 22. A beta-adrenergic agonist (bronchodilator) is used to: a. Cause bronchodilation. b. Reduce respiratory secretions. c. Increase the respiratory rate. d. Decrease the amount of air entering the lungs.
Answer: A Cause bronchodilation. Rationale: A. The primary action of beta-adrenergic agonists such as bronchodilators is to relax smooth muscle. B. A beta-adrenergic agonist would not reduce respiratory secretions C. this is an adverse effect, but not indication. D. This is not related to bronchodilation, and would increase the amount of air.
38.19 Which of the following over-the-counter (OTC) antihistamine combinations contains an analgesic property? a. Drixoral Allergy and Sinus Extended b. Sudafed PE Nighttime c. Tavist Allergy 12-hour d. Triaminic Cold/Allergy
Answer: A Drixoral Allergy and Sinus Extended Rationale: A. Drixoral Allergy and Sinus Extended contains acetaminophen. B. Sudafed PE Nighttime contains diphenhydramine and Phenylephrine. C. Tavist Allergy 12-hour contains clemastine. D. Triaminic Cold/Allergy contains chlorpheniramine and phenylephrine.
39.19 Leukotriene modifiers are primarily used for: a. Prophylaxis of asthma symptoms. b. Infection. c. Bronchodilation in asthma. d. Status asthmaticus.
Answer: A Prophylaxis of asthma symptoms. Rationale: A. Leukotriene modifiers are used primarily for prophylaxis and reducing inflammatory components. B. Leukotrienes do not reduce infection. C. Anticholinergics are bronchodilators. D. Leukotrienes are not used for treatment of status asthmaticus.
Which of the following does the nurse understand places the child with myelomeningocele at high risk for infection? A) Neurogenic bladder B) Bowel incontinence C) Latex allergy D) Exposure of sac E) Corticosteroid use
Answer: A and D. Neurogenic bladder is the failure of the bladder to either store urine properly or empty itself of urine. Because of this urinary stasis occurs in the bladder placing the child at risk for infection. In myelomeningocele, the spinal cord is exposed, placing the child at high risk for infection. Immediate surgery is needed to help prevent infection from occurring. Bowel incontinence often occurs in children with myelomeningocele, but does not pose the same health risks as urinary incontinence. Latex allergy, although common, would not promote risk for infection alone. Corticosteroid use is not common in children with myelomeningocele.
Which of these clients is best to assign to an LPN/LVN working on the telemetry unit? a. A client with heart failure who is receiving dobutamine (Dobutrex) b. A client with restrictive cardiomyopathy who uses oxygen for exertional dyspnea c. A client with pericarditis who has a paradoxical pulse and distended jugular veins d. A client with rheumatic fever who has a new systolic murmur
Answer: A client with restrictive cardiomyopathy who uses oxygen for exertional dyspnea Rationale: This client, who needs oxygen only with exertion, is the most stable; administration of oxygen to a stable client is within the scope of LPN/LVN practice.
A patient is ordered furosemide to be given via intravenous push. Which interventions will the nurse perform? (Select all that apply). A) Administer at a rate no faster than 20 mg/min. B) Assess lung sounds before and after administration. C) Assess blood pressure before and after administration. D) Maintain accurate intake and output record. E) Monitor the electrocardiogram continuously. F) Insert an arterial line for continuous blood pressure monitoring.
Answer: A, B, C, D. Furosemide can be infused via intravenous push at the rate of 20 mg/min. Furosemide is a diuretic and will decrease fluid in alveoli, and assessing lung sounds can help to determine therapeutic effect. Blood pressure should decrease with the administration of a diuretic. It is appropriate to monitor before and after administration. It is appropriate to monitor intake and output for a patient receiving a diuretic. There is no need to insert an arterial line to continuously monitor the blood pressure since it should not fluctuate that dramatically. Also, there is no need to continuously monitor the electrocardiogram because the medication is not cardiotoxic.
A patient is to start disulfiram to help with alcohol use disorder. The nurse providing medication education about the drug will include which topics in the education plan? (Select all that apply.) A) Importance of taking the medication every day B) That better results are experienced when a support group helps with treatment adherence C) Common food and hygiene products that contain alcohol D) That disulfiram treatment should be stopped 1 day before alcohol consumption E) That disulfiram works by disrupting the metabolism of alcohol F) That use of alcohol with disulfiram may cause nausea and vomiting and may even be fatal
Answer: A, B, C, E, F
The 7 year old patient has had a cast on to heal his fracture of his arm. After the expected time period, the nurse is teaching a child about what to expect when removing his cast. Which of the following teaching points should the nurse include? Select All that Apply: A) "The cast could begin to feel really warm as the striker saw is taking the cast off" B) "The striker saw will be very loud" C) "Look, see, the saw won't be able to cut your skin" D) "Once the cast is removed we will soak your leg in warm water" E) "you will still need to keep your leg very still even after the cast is removed"
Answer: A, B, C, and D. The cast/extremity under the cast could begin to feel warm during the cast removal process. The saw could be loud, but the nurse should demonstrate on him/herself that the saw can't won't cut the child. Once the cast is removed, it will be soaked and washed in warm soapy water, and it should be soaked in warm water daily. All of these need to be communicated to the child on the level of their understanding. The child should be told to start increasing activity the limb to regain strength and range of motion.
A patient has nine drugs prescribed to take daily. Which are common reasons for nonadherence to the drug regimen in an older adult? (Select all that apply.) A) Taking multiple drugs at one time B) Impaired memory C) Decreased dexterity D) Increased mobility E) Increased visual acuity
Answer: A, B, C.
Which of the following disorders would be considered medically appropriate for the use of anabolic-androgenic steroids (AAS)? A) Delayed puberty. B) Hypogonadism. C) Cachexia. D) Appetite suppression. E) Muscle growth.
Answer: A, B, C. Anabolic-androgenic steroids (AAS) are synthetic agents used to treat conditions caused by low levels of testosterone in the body, such as delayed puberty, hypogonadism, and cachexia related to chronic disease states.
The nurse understands that the risk for drug toxicity in the first year of life can be due to which of the following factors. (Select all that apply). A) Immaturity of the liver. B) Alterations in blood flow to tissues. C) Decreased protein and protein-binding sites. D) Increased renal perfusion. E) Increased muscle mass.
Answer: A, B, C. Neonates and infants have immature livers, decreased protein concentrations compared with adults, and they have fewer protein receptor sites with an affinity for drug binding in the first 12 months after birth; this results in higher levels of unbound drug and an increased risk of drug toxicity.
The patient is caring for the patient receiving nitroprusside. Which interventions should be included in the nurse's plan of care? A) Monitor for thiocyanate levels. B) Protect fluid bag from light. C) Provide continuous blood pressure monitoring. D) Monitor potassium levels. E) Assess chest pain level.
Answer: A, B, C. Nitroprusside is used for hypertensive emergencies as well as emergency management for heart failure. The drug can be administered over 24 h but decomposes in light, so the container must be wrapped in opaque material, such as aluminum foil. Discard drug if red, green, or blue. Measure cyanide and thiocyanate levels. May cause confusion, hypotension, bradycardia, tachycardia, dizziness, headache, palpitations, ataxia, seizures, cyanide or thiocyanate toxicity, and methemoglobinemia.
When conducting a cultural assessment of a patient, what will the nurse include in the assessment? (Select all that apply). A) Touch preferences. B) Perception of time. C) Eye contact preference. D) Sexual orientation. E) Ability to speak English.
Answer: A, B, D.
A patient who has angina is prescribed nitroglycerin. Which are appropriate nursing interventions for nitroglycerin? (Select all that apply.) A) Have the patient sit or lie down when taking a nitroglycerin sublingual tablet. B) Teach the patient who has taken a tablet to call 911 in 5 minutes if chest pain persists. C) Apply the nitroglycerin patch to a hairy area to protect skin from burning. D) Call the health care provider after taking five tablets if chest pain persists. E) Warn the patient against ingesting alcohol while taking nitroglycerin.
Answer: A, B, E.
Which of the following could the nurse do to assess for hypotonia of the 4 month-old infant? SATA: A) Pick up the child and see if the child feels like it is slipping out of the nurse's grasp B) Assess to see if the child can momentarily support his own weight when placed in a standing position C) Hold the child up and ask them to walk forward for a few steps D) Move the infant from the supine position to the sitting position and see if the child can hold up his own neck E) Move the infants muscles and note any muscle spasms not associated with the muscle movement
Answer: A, B, and D. Hypotonia is often an indicator that the child has some form of neuromuscular disorder. The feeling that the child is slipping out of the examiners hands is often as sign of hypotonia. By four months the child is often able to support their own neck and to stand momentarily when their feet are placed on a flat surface and their body is in the vertical position. The child would not be able to walk on command at this age. Assessing for extraneous muscle spasms would indicate the presence of hypertonia, not hypotonia.
The nurse anticipates which of the following orders for the patient with Duchenne Muscular Dystrophy? Select all that apply: A) Prednisone B) Calcium supplements C) Bedrest D) Botulinum Toxin E) Chest percussion
Answer: A, B, and E. Corticosteroids are thought to help slow the progression of the disease. Calcium supplements are provided to help with the long-term effects of osteoporosis caused by the corticosteroids. Chest percussion can help remove excess secretions from the respiratory tract that the patient may be too weak to expel by themselves. Bedrest or use of botulinum toxin would not be recommended for this patient.
The nurse is caring for the patient with Russel's traction. Which of the following should the nurse include in this patients plan of care? SATA: A) Weight should remain off of the floor at all times B) Place a foot support to prevent foot drop C) Release traction for 5 minutes of every hour to provide skin care D) Ensure heel is resting on bed at all times E) Assess neurovascular status q 4 hours
Answer: A, B, and E. With all traction, the weights should remain off of the floor at all times and should not be released periodically or stopped for any reason unless emergent. A foot support will be needed for this patient because foot drop could develop related to the heel being elevated without support. The heel should be off of the bed at all times, not resting on it. Neurovascular status should be assessed often on this patient (as often as vitals are done).
The Principle of Atraumatic Care includes (select all that apply): A) Pain management B) Collaborative care with family members C) Restraining infants to administer drugs D) Keeping the child apart from family members when administering drugs
Answer: A, B.
What factors contribute to polypharmacy in the elderly? (Select all that apply.) A) Multiple health care providers B) Multiple chronic diseases C) Use of a single pharmacy D) Care coordination by a nurse E) Few hospitalizations
Answer: A, B.
Which symptoms are likely to be produced by abuse of cannabis? A) Relaxation. B) Heightened sensation of time. C) Euphoria. D) Lack of motivation. E) Emotional liability
Answer: A, C, D, E. Cannabis abuse is most likely to produce a slowed sensation of time rather than a heightened sensation.
Which of the following symptoms would the nurse expect to possibly see in the child with Duchenne muscular dystrophy? Select all that apply a) Protuberant belly b) Diminished intelligence c) Walking on the toes or balls of feet d) Gower's sign e) Spinal curvatures
Answer: A, C, D, and E. To protect balance, which is impaired in this disorder, the child may often have their belly sticking out with their shoulders pulled back. They often have a waddling gait and walk on the toes or on the balls of the feet. Gower's sign is the use of a special technique in order to rise off of the floor. Spinal curvatures often occur as the muscles in the body atrophy (including lordosis, kyphosis, and scoliosis). Intelligence is rarely affected by this disorder.
A nurse caring for a child with developmental delay prepares to teach the patient about prescribed drugs. Which actions are essential to ensure patient safety? (Select all that apply.) A) Assess the child's developmental age. B) Assess for side effects the same as those experienced by adults. C) Consider the actions and uses of the drug. D) Focus on the child's chronologic age. E) Involve the family in teaching sessions.
Answer: A, C, E.
The nurse is developing teaching materials for an 82-year-old African-American man with macular degeneration, who is being discharged on two new drugs. Which strategies would be best to use to impart the information? (Select all that apply.) A) Limit distractions in the room when teaching. B) Wait until discharge to teach so information is fresh in the memory. C) Augment teaching with audio material. D) Use Honey and other terms of familiarity to promote trust.

Knowing that the albumin in neonates and infants has a lower binding capacity for medications, the nurse anticipates that the health care provider will order which adjustment to minimize the risk of toxicity? A) A decrease in the dosage of drug given B) An increase in the dosage of drug given C) A shorter time interval between doses D) Intravenous administration of the drug
Answer: A. A lower binding capacity leaves more drug available for action; thus, a lower dose would be required to prevent toxicity. An increase in the drug dose would result in higher risk of toxicity. A shorter time interval between doses would increase the risk of toxicity. IV administration of a drug may increase the risk of toxicity due to quicker onset of action.
A patient is to be discharged with a transdermal nitroglycerin patch. Which instruction will the nurse include in the patient's teaching plan? A) "Apply the patch to a non-hairy area of the upper torso or arm." B) "Apply the patch to the same site each day." C) "If you have a headache, remove the patch for 4 hours and then reapply." D) "If you have chest pain, apply a second patch next to the first patch."
Answer: A. A nitroglycerin patch should be applied to a non-hairy area for the best and most consistent absorption rates. Sites should be rotated to prevent skin irritation. The drug should be continued if headache occurs, as tolerance will develop. Sublingual nitroglycerin should be used to treat chest pain.

Answer: A. A therapeutic INR is 2-3. The patient needs more warfarin to reach a therapeutic level.
What effect may physiological changes due to aging in the older adult's cardiac system have on drug administration in this patient? A) Delayed transportation of drugs to the body tissues. B) Slowed absorption of oral drugs. C) Increased transportation of drugs to the body tissues. D) Increased absorption of oral drugs.
Answer: A. Administration of medication to an older adult can result in delayed transportation of the drugs to the tissues because of changes in the older adult's cardiac system. The cardiac system usually will not cause slower absorption of oral drugs.
The nurse is administering medication to an older adult. The nurse anticipates that this patient's hepatic system will have which effect on the medication? A) The medication will be excreted quicker. B) The medication will be metabolized more slowly. C) The medication will be excreted more slowly. D) The medication will be metabolized quicker.
Answer: A. Administration of medication to an older adult can result in the drug being metabolized more slowly in the body. The hepatic system will not affect the excretion of the drug.
Which nursing intervention is essential for the patient receiving alteplase? A) Assess for reperfusion dysrhythmias. B) Monitor liver enzymes. C) Administer prescribed vitamin K if bruising is observed. D) Monitor blood pressure and stop the medication if blood pressure drops below 110 systolic.
Answer: A. Alteplase can cause bleeding as well as reperfusion dysrhythmias. Alteplase does not directly affect liver enzymes. Vitamin K will not reverse the effects of alteplase. Vital sign changes can alert the nurse to complications; however, a blood pressure below 110 systolic is not, in itself, cause for alarm.
The patient arrives at the health clinic complaining of experiencing sudden onset of both flatulence and heartburn. The patient tells the nurse that he has added herbal medication to his drug regimen. Based on the symptoms being experienced, the nurse expects that the patient has been taking which herb? A) Garlic.

Answer: A. Although both sage and milk thistle can produce occasional gastrointestinal upset, of the herbs listed, only garlic is known to produce both flatulence and heartburn.
A nurse is caring for a patient who is taking an angiotensin-converting enzyme inhibitor and develops a dry, nonproductive cough. What is the nurse's priority action? A) Call the health care provider to switch the medication. B) Assess the patient for other symptoms of upper respiratory infection. C) Instruct the patient to take antitussive medication until the symptoms subside. D) Tell the patient that the cough will subside in a few days.
Answer: A. Angiotensin-converting enzyme inhibitors prevent the breakdown of bradykinin, frequently causing a nonproductive cough. Angiotensin receptor blocking agents do not block this breakdown, thus minimizing this annoying side effect. The patient should be switched to a different medication if the side effect cannot be tolerated.
What statement indicates to the nurse that the patient needs additional instruction about antihypertensive treatment? A) "I will check my blood pressure daily and take my medication when it is over 140/90." B) "I will include rest periods during the day to help me tolerate the fatigue my medicine may cause." C) "I will change my position slowly to prevent feeling dizzy." D) "I will not mow my lawn until I see how this medication makes me feel."
Answer: A. Antihypertensive medications need to be taken routinely to maintain a normotensive state and prevent occurrence of complications. Many patients do not adhere to this regimen because hypertension itself does not cause symptoms, whereas the medication can cause some untoward effects. Patient teaching is essential. If the patient indicates that he will take rest periods and change positions slowly to avoid orthostatic hypotension, he is demonstrating compliance with the treatment regimen.
A patient is prescribed an antitussive medication. What is the most important instruction for the nurse to include in the patient teaching? A) "This medication may cause drowsiness and dizziness." B) "Watch for diarrhea and abdominal cramping." C) "This medication may cause tremors and anxiety." D) "Headache and hypertension are common side effects."
Answer: A. Antitussive medications also affect the central nervous system, thus causing drowsiness and dizziness. There is no reason to anticipate that the medication will cause diarrhea, abdominal cramping, tremors and anxiety, or headache and hypertension.
The nurse administers a medication that has a long half-life to an older adult patient. What is a priority action for the nurse? A) Assess the patient for potential drug toxicity. B) Consult with the health care provider for an alternative drug. C) Administer medications early in the day. D) Administer one-half of the medication at a time.
Answer: A. Because drug absorption is slowed in the older adult, drugs with a longer half-life may increase the potential for toxicity. The nurse should assess the patient, and the dose may need to be decreased. An alternative drug should not be needed. The time of administration will not affect the half-life. The medication should not be halved; this will not affect the half-life.
What is a priority nursing diagnosis for a patient taking an antihypertensive medication? A) Alteration in cardiac output related to effects on the sympathetic nervous system. B) Knowledge deficit related to medication regimen. C) Fatigue related to side effects of medication. D) Alteration in comfort related to nonproductive cough.
Answer: A. Circulation is always a priority over fatigue, pain, and knowledge deficit.
The nurse would question an order for colesevelam (Welchol) if the patient has which condition in the medical history? A) Impaction. B) Glaucoma. C) Hepatic disease. D) Renal disease.
Answer: A. Colesevelam binds with bile in the intestinal tract to form an insoluble complex. It can also bind to other substances and lead to intestinal obstruction.
An older adult patient has been diagnosed with hypertension. A diuretic has been prescribed. Which assessment finding will most concern the nurse? A) The patient's heart rate is irregular. B) The patient is complaining of symptoms of a cold. C) The patient has a blood pressure of 140/90 mm Hg. D) The patient's temperature is 98.4°F.

B) "Patients who abuse drugs may have a brain disorder." C) "Addictive disorders are not normally treatable." D) "Patients with addictive disorders cannot take narcotics."
Answer: A. Genetics may play a role in contributing to substance abuse. Patients do not have brain disorders; however, their brains do become altered over time due to repeated ingestion of certain drugs. Addictive disorders are treatable. Patients with addictive disorders may not be addicted to narcotics and therefore can take narcotics.
The nurse is caring for a patient with a history of alcoholism who is undergoing long-term alcohol treatment. Which intervention is the highest priority? A) Ensuring the patient knows all alcohol must be avoided when taking disulfiram. B) Teaching the patient about flumazenil. C) Monitoring the patient with methadone administration. D) Administering propranolol daily
Answer: A. In addition to cognitive behavioral therapy, disulfiram may be ordered because it prevents alcohol consumption by causing an unpleasant reaction if alcohol is taken. Flumazenil is a benzodiazepine antagonist and is used to treat benzodiazepine overdose. Methadone is an opioid agonist used during opioid detoxification to decrease symptoms and is used in long-term management of opioid addiction. Propranolol is an adrenergic beta blocker and is indicated in treating elevated blood pressure and tachycardia, which may occur with amphetamine toxicity.
Which assessment indicates to the nurse a therapeutic effect of mannitol has been achieved? A) Decreased intracranial pressure. B) Decreased potassium. C) Increased urine osmolality. D) Decreased serum osmolality.
Answer: A. Mannitol is an osmotic diuretic that pulls fluid from extravascular spaces into the bloodstream to be excreted in urine. This will decrease intracranial pressure, increase excretion of medications, decrease urine osmolality, and increase serum osmolality.
Which route is most commonly used in pediatric medication administration? A) Oral. B) Fecal. C) Subcutaneous. D) Intramuscular.

Answer: B.
While getting dressed to go home after minor outpatient surgery on his leg for removal of a mole, a 62-year-old patient notifies the nurse that he has severe chest pain. He is also diaphoretic and complains of shortness of breath. The surgeon is notified and orders administration of aspirin 325 mg by mouth while quickly making arrangements to transfer the patient to the emergency department. Which is the best course of action by the nurse? A) Question the aspirin order because the patient just had a surgical procedure and might have bleeding complications. B) After checking for drug allergies, first instruct the patient to chew the aspirin tablet and then administer the aspirin. C) After checking for drug allergies, instruct the patient to swallow the aspirin tablet whole. D) Suggest to the surgeon that the enteric-coated form of aspirin might be better tolerated by the patient to avoid gastrointestinal distress.
Answer: B.
The patient asks the nurse to explain the difference between dalteparin and heparin. Which response by the nurse is accurate? A) "There is no real difference. Dalteparin is preferred because it is less expensive." B) "Dalteparin is a low-molecular-weight heparin that is more predictable in its effect and has a lower risk of bleeding." C) "I'm not sure why some health care providers choose dalteparin and some heparin. You should ask your doctor." D) "The only difference is that heparin dosing is based on the patient's weight."
Answer: B. A low-molecular-weight heparin is more predictable in its effect than regular heparin. Dalteparin is more expensive than heparin and is dosed based on the patient's weight. It is not appropriate to provide the patient with no instruction other than to simply refer to the health care provider.
What instruction should the nurse provide to the patient who needs to apply nitroglycerin ointment? A) Use the fingers to spread the ointment evenly over a 3-inch area. B) Apply the ointment to a non-hairy part of the upper torso. C) Massage the ointment into the skin. D) Cover the application paper with ointment before use.
Answer: B. Absorption is best over a non-hairy portion of skin. The upper torso is the preferred site of application. The nurse should wear gloves and squeeze the ointment onto the application patch. Massaging in the ointment is not appropriate. The paper should not be covered with ointment. The ointment is measured as one straight line on the nitroglycerin paper and is then gently spread around and applied, but not rubbed, into the skin.
A patient is prescribed a beta blocker. Beta blockers are as effective as antianginals because they do what? A) Increase oxygen to the systemic circulation B) Maintain heart rate and blood pressure C) Decrease heart rate and decrease myocardial contractility D) Decrease heart rate and increase myocardial contractility
Answer: C.
The health care provider orders ipratropium bromide, albuterol, and beclomethasone inhalers for a patient. What is the nurse's best action? A) Question the order; three inhalers should not be given at one time. B) Administer the albuterol, wait 5 min, administer ipratropium bromide, then beclomethasone several minutes later. C) Administer each inhaler at 30-min intervals. D) Administer beclomethasone, wait 2 min, administer ipratropium bromide, then albuterol several minutes later.
Answer: B. Administering the bronchodilator albuterol first allows the other drugs to reach deeper into the lungs as the bronchioles dilate. Anticholinergics such as ipratropium bromide also help the bronchodilator, but to a lesser extent. Corticosteroids such as beclomethasone do not dilate and are therefore given last.
Which nursing intervention will decrease the flushing reaction of niacin? A) Administering niacin with an antacid B) Administering aspirin 30 min before nicotinic acid. C) Administering diphenhydramine hydrochloride (Benadryl) with niacin. D) Applying cold compresses to the head and neck
Answer: B. Administration of an anti-inflammatory agent such as aspirin has been shown to decrease the flushing reaction associated with niacin. In addition, avoiding hot beverages, such as coffee, when taking niacin may also prevent flushing.
What effect may the physiological changes of aging in the older adult's gastrointestinal system have on drug administration? A) Delayed transportation of drugs to the body tissues. B) Slowed absorption of oral drugs. C) Increased transportation of drugs to the body tissues. D) Increased absorption of oral drugs.
Answer: B. Administration of medication to an older adult can result in slowed absorption of oral drugs. The gastrointestinal system changes will not usually result in a change in the transportation of drugs to the body tissues.
The patient asks the nurse how nitroglycerin should be stored while traveling. What is the nurse's best response? A) "You can protect it from heat by placing the bottle in an ice chest." B) "It's best to keep it in its original container away from heat and light." C) "You can put a few tablets in a resealable bag and carry in your pocket." D) "It's best to lock them in the glove compartment to keep them away from heat and light."
Answer: B. Although nitroglycerin needs to be kept in a cool, dry place, it should not be placed in an ice chest where it could freeze. It should also not be locked up and must be kept away from light, not in a clear plastic bag.
When caring for patients with varied cultural backgrounds, the nurse will recognize that: A) cultural considerations will not be a concern if patient's health needs are significant. B) generalizations about behavior of a specific cultural group may not be accurate. C) current health standards will determine if cultural practices can be utilized. D) similar reactions to stress occur when patients have the same cultural background.
Answer: B. Any time that generalizations are made about a patient group, they will usually be inaccurate since nursing care must be individualized to the specific patient. Cultural considerations must always be a major concern for the nurse regardless of the condition of the patient.
The nurse is teaching the patient on the use of beclomethasone. Which statement by the patient indicates an understanding of the teaching? A) "I will need to taper off the medication to prevent acute adrenal crisis." B) "This medication will help prevent the inflammatory response of my allergies." C) "I will need to monitor my blood sugar more closely because it may increase." D) "I need to take this medication only when my symptoms get bad."
Answer: B. Beclomethasone is a steroid spray administered nasally. It is used to prevent allergy symptoms. Its effect is localized, and therefore the patient does not have systemic side effects with normal use and does not have to worry about weaning off the medication as with oral corticosteroids. Because the medication has a localized effect, it will not produce the changes in blood sugar that would be generated by systemic steroids.
Which statement indicates the patient understands discharge instructions regarding cholestyramine? A) "I will take cholestyramine 1 h before my other medications." B) "I will increase fiber in my diet." C) "I will weigh myself weekly." D) "I will have my blood pressure checked weekly."
Answer: B. Cholestyramine can cause constipation; thus, increasing fiber in the diet is appropriate. All other drugs should be taken 1 h before or 4 h after cholestyramine to facilitate proper absorption.
Which physiological factor that exists in children leads to decreased drug concentrations? A) Increase in adipose tissue B) Increase in body fluid proportions. C) Decrease in albumin. D) Decrease in liver function.
Answer: B. Drug distribution is affected by factors such as body fluid composition, body tissue composition, protein-binding capability, and effectiveness of various barriers to drug transport. In neonates and infants, the body is about 75% water, compared with 60% in adults. This increased body fluid proportion allows for a greater volume of fluid in which to distribute drugs, which results in a lower drug concentration.
Which factor takes priority in considering drug dosage in children? A) Child's age. B) Child's weight in kilograms. C) Child's fluid intake. D) Child's birthweight.
Answer: B. Drugs for pediatric patients are ordered based on either the child's weight in kilograms (mg/kg) or on body surface area (BSA or mg/m
The patient is started on ezetimibe for elevated cholesterol. The nurse demonstrates understanding of the mechanism of action of this drug when including which statement in the patient education presentation? A) This drug inhibits cholesterol synthesis in the liver. B) This drug inhibits cholesterol absorption in the bowel. C) This drug sequesters bile acids in the small bowel. D) This drug increases pancreatic secretion facilitating lipid breakdown.
Answer: B. Ezetimibe is a cholesterol absorption inhibitor that acts on the cells in the small intestine to inhibit cholesterol absorption. It decreases cholesterol from dietary absorption, reducing serum cholesterol.
Which assessment finding in a patient taking an HMG-CoA reductase inhibitor will the nurse act on immediately? A) Decreased hemoglobin. B) Elevated liver function tests. C) Elevated HDL. D) Elevated LDL.
Answer: B. HMG-CoA reductase inhibitors (statins) can cause hepatic toxicity; thus, it is necessary to monitor liver function tests. The nurse should act on this finding immediately. Decreased hemoglobin should be addressed but not immediately. It is most likely not related to the administration of the HMG-CoA reductase inhibitor. Also, while an elevated LDL level must be addressed, it is not as high a priority as the elevated liver function test results. An elevated HDL is a positive finding and an encouraging result.
Which laboratory value will the nurse report to the health care provider as a potential adverse response to hydrochlorothiazide? A) Sodium level of 140 mEq/L B) Fasting blood glucose level of 140 mg/dL. C) Calcium level of 9 mg/dL. D) Chloride level of 100 mEq/L
Answer: B. Hydrochlorothiazide can cause hyperglycemia. Normal calcium level is approximately 8.8-10.3 mg/dL; normal sodium level is 135-147 mEq/L; normal chloride level is 95-107 mEq/L, and normal fasting blood glucose should be 60-110 mg/dL.
The nurse is caring for a patient whose cultural background places a great emphasis on respect for personal space. In order to properly care for this patient, what will the nurse do? A) Avoid touching the patient while providing care. B) Explain all nursing care delivered prior to touching the patient. C) Limit the number of visitors allowed to see the patient. D) Maintain a specific distance from the patient at all times.
Answer: B. In order to properly provide nursing care, it will be necessary to occasionally touch the patient. To respect the patient's cultural beliefs, the nurse should explain the reason for care provided and procedures completed prior to implementing them
Which statement is true regarding the drug information available concerning pediatric patients? A) Information is derived primarily from animal studies. B) Information is derived from smaller adult studies. C) Information is based on smaller studies with ill children. D) Information is the best guess due to lack of any studies on children.
Answer: B. Information regarding drug therapy in the pediatric population is most often based on smaller adult studies. Rarely, studies may be conducted on well children. Animal studies may be used initially but are not the primary source of information.
What is the most important thing for the nurse to teach a patient who is switching allergy medications from diphenhydramine to loratadine? A) Loratadine can potentially cause dysrhythmias. B) Loratadine has fewer sedative effects. C) Loratadine has increased bronchodilating effects. D) Loratadine causes less gastrointestinal upset.
Answer: B. Loratadine does not affect the central nervous system and therefore is non-sedating. There is insufficient evidence to indicate that loratadine can cause dysrhythmias, can act as a bronchodilator, or cause gastrointestinal upset than other comparable medications.
A patient diagnosed with hypercholesterolemia is prescribed lovastatin. Based on this medication order, the nurse will contact the health care provider about which reported condition in the patient's history? A) Chronic pulmonary disease. B) Hepatic disease. C) Leukemia. D) Renal disease.
Answer: B. Lovastatin can cause an increase in liver enzymes and thus should not be used in patients with preexisting liver disease.
In addition to its benefit in reducing pain and anxiety in the patient with pulmonary edema, the nurse understands morphine produces which primary effect on the pathophysiology of pulmonary edema? A) Decreasing the conduction rate at the AV node B) Morphine sulfate is also indicated for acute pulmonary edema because it produces venous vasodilation that decreases cardiac preload, the amount of blood returning to the right ventricle. The net effect is a decrease in pulmonary venous congestion. C) Morphine sulfate is also indicated for acute pulmonary edema because it produces venous vasodilation that decreases cardiac preload, the amount of blood returning to the right ventricle. The net effect is a decrease in pulmonary venous congestion. D) Morphine sulfate is also indicated for acute pulmonary edema because it produces venous vasodilation that decreases cardiac preload, the amount of blood returning to the right ventricle. The net effect is a decrease in pulmonary venous congestion.
Answer: B. Morphine sulfate is also indicated for acute pulmonary edema because it produces venous vasodilation that decreases cardiac preload, the amount of blood returning to the right ventricle. The net effect is a decrease in pulmonary venous congestion.
A patient receiving intravenous nitroglycerin at 20 mcg/min complains of dizziness. Nursing assessment reveals a blood pressure of 85/40 mm Hg, heart rate of 110 beats/min, and respiratory rate of 16 breaths/min. What is the nurse's priority action? A) Assess the patient's lung sounds. B) Decrease the intravenous nitroglycerin by 10 mcg/min. C) Stop the nitroglycerin infusion for 1 h and then restart. D) Continue the infusion and recheck the patient's vital signs in 15 min.
Answer: B. Nitroglycerin, as a vasodilator, causes a decrease in blood pressure. Because it is short-acting, decreasing the infusion rate will allow the blood pressure to rise. The patient should be monitored every 10 min while changing the rate of the intravenous nitroglycerin infusion.
A patient is prescribed a noncardioselective beta1 blocker. What nursing intervention is a priority for this patient? A) Assessment of blood glucose levels. B) Auscultation of the lungs. C) Orthostatic blood pressure assessment. D) Teaching about potential tachycardia
Answer: B. Noncardioselective beta blockers can cause bronchospasms, and a respiratory assessment is indicated to check for potential respiratory side effects. Assessment of blood glucose and teaching about tachycardia will not be priorities.
The nurse notes that the patient is receiving hydrochlorothiazide for hypertension. Which additional medication in the patient's drug regimen would cause concern on the part of the nurse? A) Maalox. B) Digoxin. C) Nitroglycerine. D) Albuterol.
Answer: B. Of the numerous thiazide drug interactions with hydrochlorothiazide, the most serious occurs with digoxin. Thiazides can cause hypokalemia, which enhances the action of digoxin, and digitalis toxicity can occur.
A patient complains of worsening nasal congestion despite the use of oxymetazoline nasal spray every 2 h. What is the nurse's most appropriate response? A) "Oxymetazoline is not an effective nasal decongestant." B) "Overuse of nasal decongestants results in rebound congestion." C) "Oxymetazoline should be administered every hour for severe congestion." D) "You are probably displaying an unexpected reaction to oxymetazoline."
Answer: B. Oxymetazoline is an effective nasal decongestant, but overuse results in worsening or "rebound" congestion. It should not be used more than every 4 h. To avoid future rebound congestion with nasal sprays, it is recommended that they be used for no more than 3-5 days.
The nurse is completing the admission history for a patient who tells the nurse that he takes valerian. Based on the use of this herb, the nurse anticipates that the patient will most likely report experiencing which condition? A) Muscle aches. B) Headaches. C) Insomnia. D) Dry eyes.
Answer: B. Valerian has been shown to produce anxiety, headache, and gastrointestinal upset. It is not known to produce muscle aches, insomnia, or dry eyes.
The nurse is observing a nursing student giving medications to a group of patient. Which observation of the student by the nurse would suggest the need for additional cultural sensitivity on the part of the student? A) The student suggests a female nurse provide care for the patient of Muslim ethnicity. B) The student gently pats the head of a patient of East Indian ethnicity as encouragement for the patient to take all of the medications ordered. C) The student allows moments of silence when intervening with a patient of Asian American ethnicity. D) The student avoids making direct eye contact with a patient of Asian ethnicity.
Answer: B. Patients of Asian descent often avoid direct eye contact. Muslim woman will likely prefer to be cared for by a female nurse rather than a male nurse. East Asians consider a pat on the head to be offensive due to the belief that the head is sacred. Asian Americans and Native Americans may be comfortable with periods of silence, whereas persons of Latin American, African, Middle Eastern, or European descent may be uneasy during these periods.
A patient taking warfarin asks for an aspirin for a headache. What is the nurse's best action? A) Administer 650 mg of acetylsalicylic acid (ASA) and reassess pain in 30 min. B) Teach the patient of potential drug interactions with anticoagulants. C) Explain to the patient that ASA is contraindicated and administer ibuprofen as ordered. D) Explain that the headache is an expected side effect and will subside shortly.
Answer: B. Patients taking an anticoagulant should not use medications that would further increase the risk of bleeding, which includes aspirin as well as ibuprofen. Aspirin should not be administered to the patient taking other anticoagulants, unless it is ordered specifically as a low-dose daily therapy. Ibuprofen is not the best choice of medication for the patient receiving warfarin. Acetaminophen would be preferred for pain relief. Headache is not an expected side effect of warfarin therapy.
A patient has arrived at the emergency department and requires immediate surgery. He has been receiving heparin. Which intervention is essential? A) Teach the patient about the phenytoin. B) Administer protamine sulfate. C) Assess the INR before surgery. D) Administer vitamin K.
Answer: B. Protamine sulfate binds with heparin in the bloodstream to inactivate it and thus reverse its effect. Allowing the patient to undergo surgery while receiving heparin would be life-threatening. The situation should be reversed immediately, without the nurse taking the time to assess the INR or administer vitamin K. It is not appropriate to teach the patient about phenytoin since it has not been ordered for the patient.
What is the best information for the nurse to provide to the patient who is receiving spironolactone and furosemide (Lasix) therapy? A) Moderate doses of two different diuretics are more effective than a large dose of one. B) This combination promotes diuresis but decreases the risk of hypokalemia. C) This combination prevents dehydration and hypovolemia. D) Using two drugs increases the osmolality of plasma and the glomerular filtration rate.
Answer: B. Spironolactone is a potassium-sparing diuretic; furosemide causes potassium loss. Giving these together minimizes electrolyte imbalance. It is not accurate to state that the drug combination prevents dehydration and hypovolemia or that it increases the osmolality of plasma and the glomerular filtration rate. Stating that giving two different diuretics is more effective is not specific enough information for the patient
A patient is receiving an intravenous heparin drip. Which laboratory value requires immediate action by the nurse? A) Platelet count of 150,000. B) Activated partial thromboplastin time (aPTT) of 120 sec. C) INR of 1.0 D) Blood urea nitrogen (BUN) level of 12 mg/dL
Answer: B. The aPTT value of 120 sec is too prolonged. The heparin drip should be shut off for an hour. The typical aPTT normal reference range for a patient on anticoagulant therapy is 30-85 sec (range may vary slightly depending on the laboratory used). The normal range for BUN is 7-20 mg/dL, and the normal platelet range is 150,000-450,000.
The nurse is working with a health care worker who exhibits emotional lability, drowsiness, and decreased inhibitions. Which substance has the health care worker most likely been abusing? A) Stimulants. B) MDMA. C) Psychedelics. D) Inhalants.
Answer: B. The combination of emotional lability, drowsiness, decreased inhibitions, and initial relaxation is most likely to have been produced by the use of MDMA.
The nurse has been assigned to care for a patient from a cultural background that is different from that of the nurse. In order to provide appropriate care to the patient, what will the nurse do? A) Arrange for the family to provide all care so that no cultural practices are omitted. B) Identify how the patient's cultural practices and beliefs will influence his health care. C) Explain to the patient how he must adapt his practices to the hospital routine. D) Arrange for an interpreter to explain hospital practices to the patient.
Answer: B. The goal for culturally appropriate care is to identify how the patient's beliefs and practices will influence his health care, thus allowing nursing care to be properly planned for him. Having different cultural beliefs and practices does not mean that the patient speaks a different language.
The nurse is reviewing discharge medications with a patient of African American ethnicity. Which drug would the nurse question for inclusion in the medication regimen? A) A diuretic. B) An angiotensin-converting enzyme inhibitor. C) A calcium channel blocker. D) A renin inhibitor.
Answer: B. The nurse would question the inclusion of an angiotensin-converting enzyme inhibitor as African Americans respond poorly to this medication group. A diuretic, a calcium channel blocker, and a renin inhibitor can be used in this group.
The patient tells the nurse that she has a cold, is coughing, and feels like she has fluid in her lungs. What action will the nurse anticipate performing next? A) Administer dextromethorphan. B) Administer guaifenesin. C) Encourage the patient to drink fluids hourly. D) Administer fluticasone (Flonase).
Answer: B. The patient needs an expectorant. This medication will help the patient cough the fluid out of her lungs. Dextromethorphan and fluticasone will not help the patient expectorate. There is no information about the patient's fluid intake, so hourly fluids may be too much.
The patient taking methyldopa has elevated liver function tests. What is the nurse's best action? A) Document the finding and continue care. B) Notify the health care provider. C) Immediately stop the medication. D) Change the patient's diet.
Answer: B. This drug should not be used in patients with impaired liver function. The nurse should notify the health care provider so that the patient can be tapered off the medication. The nurse should not immediately stop this medication, as the patient could have a hypertensive crisis. The patient's diet is not the cause of elevated liver enzymes and should not make a difference with therapy.
A patient is started on warfarin therapy while also receiving intravenous heparin. The patient is concerned about the risk for bleeding. What will the nurse tell the patient? A) "Your concern is valid. I will call the doctor to discontinue the heparin." B) "It usually takes about 3 days to achieve a therapeutic effect for warfarin, so the heparin is continued until the warfarin is therapeutic." C) "Because of your valve replacement, it is especially important for you to be anticoagulated. The heparin and warfarin together are more effective than one alone." D) "Because you are now up and walking, you have a higher risk of blood clots and therefore need to be on both medications."
Answer: B. Warfarin works by decreasing the production of clotting factors. However, it takes approximately 3 days for the body to metabolize present clotting factors and thus achieve a therapeutic anticoagulant effect. Because of this, heparin is continued until this is achieved.
A patient is prescribed ipratropium and cromolyn sodium. What will the nurse teach the patient? A) Do not take these medications within 4 h of each other. B) Take the ipratropium at least 5 min before the cromolyn. C) Administer both medications together in a metered-dose inhaler. D) Take the ipratropium only in the mornings.
Answer: B. When using an anticholinergic in conjunction with an inhaled glucocorticoid or cromolyn, the ipratropium should be used 5 min before the steroid. This causes the bronchioles to dilate so the steroid or cromolyn can get deeper into the lungs.
A patient is prescribed aminophylline-theophylline. For what adverse effect should the nurse monitor the patient? A) Drowsiness B) Hypoglycemia C) Increased heart rate D) Decreased white blood cell count
Answer: C.
A nurse is assessing a 3 year old child in the pediatrics wellness clinic, which of the following would be least concerning to the nurse? a) The child is holding his right arm close to his chest and refusing to use it b) When the child stands with his knees together, his ankles are far apart c) The child's pelvis drops slightly whenever he walks d) The child is in the shortest percentile for his age group
Answer: B. This condition, known as genu valgum or knock-knees, a common finding in children aged 2-3 and would not be concerning to the nurse. Refusal to use a limb could be a sign of damage or fracture to that limb. Trendelenberg's sign, or the drop of the pelvis when walking, could be a sign of hip dysplasia. Being in the shortest percentile for his age group could be a sign of a growth delay possibly caused by an underlying condition.
You, the awesome sauce nurse, are working at the new equally amazing pediatric clinic that opened literally five minutes from your house (nice commute!) your first patient is a child with marked pectus excavatum. What is the top nursing diagnosis for this patient? A) Impaired mobility B) Ineffective breathing pattern C) Disturbed body image D) Chronic pain
Answer: B. children with marked pectus excavatum should have a thorough assessment of their cardiac and pulmonary function, because the funnel chest can place pressure on both of these symptoms impairing proper expansion of the lungs. Page 849.
38.22 Which of the following is a common adverse effect of antihistamines? a. Nosebleed b. Bradycardia c. Dry mouth d. Rebound congestion
Answer: C Dry mouth Rationale: A. Epistaxis, or nosebleed, usually occurs with intranasal glucocorticoids. B. Tachycardia, not bradycardia, is an adverse effect of antihistamines. C. Dry mouth is an common anticholinergic effect of antihistamines. D. Rebound congestion can occur with decongestants.
39.21 The nurse would observe for fungal infection of the throat for which class of medications? a. Mast cell inhibitors b. Beta-adrenergic agonists c. Glucocorticoids d. Methylxanthines

You should stop drinking the tea; it's a waste of time and money."
Answer: C. Patients may derive both psychological and physical benefits from taking traditional remedies, but it is essential to ensure that the traditional remedies will not interfere with the action of the conventional medications the patient has been prescribed. Because patients may achieve health benefits or psychological comfort from their traditional remedies, they should not be told that the remedies are forbidden or useless; however, they should be instructed not to continue the remedies until it has been determined that the remedies will not affect the action of the patient's conventional medications.
A patient is taking pravastatin sodium. Which assessment finding requires immediate action by the nurse? A) Headache. B) Slight nausea. C) Muscle pain. D) Fatigue.

The nurse is administering PO medications to a 2-year-old child who is belligerent. What action is the best strategy for the nurse to use? A) Explain the reason for the medication to the child. B) Ask the parent's permission before the medication is administered. C) Ask the parents to assist in calming the child. D) Administer medications intravenously.
Answer: C. The child needs to cooperate in the medication process. At this age, the best strategy is to ask the parents to assist in calming the child so that the child will take the medications. The child is too young to understand reasoning. The parents have given consent for care, so the nurse does not need to ask again before administering the medication. Obtaining the parent's permission will not make the child any more cooperative. The fact that the child is being uncooperative is not a reason to change the route of administration.

B) "I can chew the tablet for the quickest effect." C) "I will keep the tablets locked in a safe place until I need them." D) "I should sit or lie down after I take a nitroglycerin tablet to prevent dizziness."
Answer: D. Nitroglycerin is a vasodilator and can cause orthostatic hypotension, resulting in dizziness. Three doses can be taken 5 min apart. The tablet should be placed under the tongue to dissolve. The medication should be kept in a readily accessible location for immediate use should chest pain occur.
Which statement made by the patient demonstrates a need for further instruction regarding the use of nitroglycerin? A) "If I get a headache, I should keep taking nitroglycerin and use Tylenol for pain relief." B) "I should keep my nitroglycerin in a cool, dry place." C) "I should change positions slowly to avoid getting dizzy." D) "I can take up to five tablets at 3-minute intervals for chest pain if necessary."
Answer: D. Patients are taught to take up to three tablets every 5 min. If no relief from chest pain is obtained after one tablet, they should seek medical assistance and take up to two more tablets. All other responses demonstrate a good understanding by the patient.
A patient is receiving mannitol for treatment of cerebral edema. The nurse assesses a heart rate of 110 beats/min and rhonchi throughout the lung fields, and the patient complains of blurred vision. What will the nurse do? A) Continue to assess the patient. B) Encourage the patient to cough and deep breathe. C) Tell the patient to close her eyes and relax. D) Stop the infusion and call the health care provider.

An older adult patient has been having difficulty sleeping. If medications are ordered, what is a primary principle that guides the care of the patient? A) The older adult patient should not take sedative hypnotics. B) The older adult patient should be prescribed a drug with a short half-life. C) The older adult patient should alternate different sedatives every other day so as not to become dependent. D) The older adult patient should use alternative therapies and herbal remedies rather than sedatives.
Answer: D. The older adult patient may have difficulty with elimination of drugs, so a drug with a short half-life is preferable. If used correctly, sedative hypnotics are safe for the older adult. There is no benefit to giving two different sedatives to a patient. Alternative therapies and herbal remedies may be tried; however, there is no indication that they are better than traditional therapies.
The nurse is monitoring a patient during IV nitroglycerin infusion. Which assessment finding will cause the nurse to take action? A) Blood pressure 110/90 mm Hg. B) Flushing. C) Headache. D) Chest pain.
Answer: D. The patient should not continue to have chest pain while on IV nitroglycerin. This would prompt the nurse to intervene. Blood pressure of 110/90 mm Hg is not cause for concern and is expected with nitroglycerin. Headache and flushing are common side effects of nitroglycerin.
A nurse is monitoring a patient with angina for therapeutic effects of nitroglycerin. Which assessment finding indicates that the nitroglycerin has been effective? A) Blood pressure of 120/80 mm Hg B) Heart rate of 70 beats/min. C) ECG without evidence of ST changes. D) Patient stating that pain is 0 out of 10
Answer: D. The patient taking nitroglycerin should expect the therapeutic effect of absence of chest pain. It is unrealistic to expect that the patient's blood pressure, heart rate, and ECG will all be in completely normal range since variations in blood pressure and heart rate will occur as part of daily life and the patient may have some underlying cardiac disease that is producing the angina.
The nurse is caring for multiple patients on the pulmonary unit. The nurse would question the administration of prescribed epinephrine to which patient? A) The patient with a history of emphysema. B) The patient with a history of type 2 diabetes. C) The patient who is 16 years old. D)The patient with atrial fibrillation with a rate of 100

Which of the following actions of the pregnant woman would be most likely to affect the neuromuscular development of her unborn child in utero? A) The mother who says, "I drank a few alcoholic beverages in my second trimester, I just couldn't help it!" B) The 22 year old mother who started taking folic acid before she ever got pregnant C) The 27 year old mother who was involved in a car accident which caused her to go into labor D) The 19 year old who says, "I did drugs pretty bad, but I stopped as soon as I knew I was pregnant,"
Answer: D. Early in gestation, during 3-4 weeks of pregnancy, the neural tubes of the embryo begin to develop and differentiate. This is a critical time for the unborn child, and things like drug or alcohol use are most likely to cause developmental disorders during this time period.
When assessing children at the pediatric clinic, which of the following would the nurse want to investigate further? A) The two year old who gained control of his head and neck muscles before he was able to walk B) The infant who has very brisk deep tendon reflexes C) The young child who trips and falls while running around D) The infant who demonstrates hypertonia soon after birth.
Answer: D. Hypertonia of muscles or hypotonia (high or low muscle tone) would be considered abnormal findings in children and could be indicative of an underlying problem. Myelination proceeds in a cephalocaudal and proximodistal fashion, so the child would be expected to gain head control before being able to walk. Brisk deep tendon reflexes, while abnormal in older children, is normal in young infants. Tripping and falling could cause injury in the child, but would overall be considered a normal finding as children are still gaining control of their muscle function.
The nurse expects to see all of the following when assessing the newborn infant except: a) Flexible Metatarsus adductus b) Pes Planus c) Internal tibial torsion d) Polydactyly
Answer: D. Polydactyly, or the presence of an extra digit, would be considered abnormal in a newborn child. Flexible metatarsus adductus, also known as in-toeing, would be expected in the newborn infant, and would resolve as the infant matures (page 833). Internal tibial torsion, or the slight bowing of the legs, would also be expected r/t in-utero positioning. Pes Planus, or flat-footedness also occurs in infants and disappears as the child matures.
Although the client with cardiac failure is asymptomatic, the nurse suspects noncompliance with prescribed home therapy. Which laboratory test confirms the nurse's suspicions? a. B-type natriuretic peptide (BNP) 90 pg/mL b. Serum electrolytes c. Hemoglobin and hematocrit d. Digoxin level of 0.2 ng/dL
Answer: Digoxin level of 0.2 ng/dL Rationale: A therapeutic digoxin level is 0.8 to 2.0 ng/dL. A level of 0.2 ng/dL indicates that the client has not been taking his digoxin as prescribed.
The nurse prepares to administer digoxin to a client with heart failure and notes the following information: Temperature: 99.8 Pulse: 48 and irregular Respirations: 20 Potassium level: 3.2 mEq/L What action does the nurse take? a. Give digoxin; reassess the heart rate in 30 minutes. b. Give the digoxin; document assessment findings in the medical record. c. Hold the digoxin, and obtain a prescription for an additional dose of furosemide. d. Hold the digoxin, and obtain a prescription for a potassium supplement.
Answer: Hold the digoxin, and obtain a prescription for a potassium supplement Rationale: Digoxin causes bradycardia; hypokalemia potentiates digitalis. The nurse seeks to correct this situation through collaboration with the provider.

Which action should the nurse take first? a. Assess the client for peripheral edema. b. Listen to the client's posterior breath sounds. c. Notify the physician about the client's weight gain. d. Remind the client about dietary sodium restrictions.
Answer: Listen to the client's posterior breath sounds. Rationale: Because the client is at risk for pulmonary edema and hypoxemia, the first action should be to assess breath sounds.
When caring for a client who has undergone a partial left ventriculectomy, which of these new-onset clinical manifestations indicates the need for immediate action by the nurse? a. Chest pain with movement b. Fatigue after ambulation c. Muffled heart sounds d. Bi-basilar fine crackles
Answer: Muffled heart sounds Rationale: Muffled heart sounds may be a clinical manifestation of bleeding into the pericardial space; the nurse should assess the client for possible decreased cardiac output and should notify the surgeon.
Which of these nursing actions should the nurse delegate to a nursing assistant working on the medical unit? a. Determine the usual alcohol intake for a client with cardiomyopathy. b. Monitor the pain level for a client with acute pericarditis. c. Obtain daily weights for several clients with class IV heart failure. d. Check for peripheral edema in a client with endocarditis.
Answer: Obtain daily weights for several clients with class IV heart failure. Rationale: Daily weight assessment is included in the role of the nursing assistant, who will report the weights to the RN.
Which intervention will best assist the client with acute pulmonary edema in reducing anxiety and dyspnea? a. Monitor pulse oximetry and cardiac rate and rhythm. b. Reassure the client that his distress can be relieved with proper intervention. c. Place the client in high Fowler's position with the legs down. d. Ask a family member to remain with the client.
Answer: Place the client in high Fowler's position with the legs down Rationale: High Fowler's position and placing the legs in a dependent position will decrease venous return to the heart, thus decreasing pulmonary venous congestion.

The 46-year-old with aortic stenosis who takes digoxin (Lanoxin) and has new-onset, frequent premature ventricular complexes b. The 55-year-old admitted with pulmonary edema who received furosemide (Lasix) and whose current O2 saturation is 94% c. The 68-year-old with pericarditis who is reporting sharp, stabbing chest pain when taking deep breaths d. The 79-year-old admitted for possible rejection of a heart transplant who has sinus tachycardia, rate 104
Answer: The 46-year-old with aortic stenosis who takes digoxin (Lanoxin) and has new-onset, frequent premature ventricular complexes Rationale: This client's premature ventricular complexes may be indicative of digoxin toxicity. Further assessment for clinical manifestations of digoxin toxicity should be done and the physician notified about the dysrhythmia.
A client admitted for heart failure has a priority problem of Excess Fluid Volume related to compromised regulatory mechanisms. Which of these assessment data obtained the day after admission is the best indicator that the treatment has been effective? a. The client has a diuresis of 400 mL in 24 hours. b. The client's blood pressure is 122/84 mm Hg. c. The client has an apical pulse of 82 beats/min. d. The client's weight decreases by 2.5 kg.
Answer: The client's weight decreases by 2.5 kg. Rationale: The best indicator of fluid volume loss is daily weight; because each kilogram represents approximately 1 L, this client has lost approximately 2500 mL of fluid.
Which nursing intervention for a client admitted today with heart failure will assist the client to conserve energy? a. Client ambulates around the nursing unit with a walker. b. The nurse monitors the client's pulse and blood pressure frequently. c. The nurse obtains a bedside commode before administering furosemide. d. The nurse returns the client to bed when he becomes tachycardic.
Answer: The nurse obtains a bedside commode before administering furosemide. Rationale: Limiting the need for ambulation on the first day of admission to sitting in a chair or performing basic leg exercises promotes physical rest and reduced oxygen demand.
The client begins therapy with lisinopril (Prinivil, Zestril). What should the nurse consider at the start of therapy with this medication? a. The client's ability to understand medication teaching b. The risk for hypotension c. The potential for bradycardia d. Liver function tests (LFTs)
Answer: The risk for hypotension Rationale: Angiotensin-converting enzyme (ACE) inhibitors are associated with first-dose hypotension and orthostatic hypotension, which are more likely in those older than 75 years.
When following up in the clinic with a client with heart failure, how does the nurse recognize that the client has been compliant with fluid restrictions? a. Auscultation of crackles b. Pedal edema c. Weight loss of 6 pounds since the last visit d. Reports sucking on ice chips all day for dry mouth
Answer: Weight loss of 6 pounds since the last visit Rationale: Weight loss in this client indicates effective fluid restriction and diuretic drug therapy
Which of the following medications acts by blocking the reabsorption of sodium and chloride in Henle's loop? a. Furosemide (Lasix) b. Chlorothiazide (Diuril) c. Spironolactone (Aldactone) d. Metolazone (Zaroxolyn)
Answer: a. Furosemide (Lasix) Rationale: Furosemide (Lasix) is a loop diuretic that blocks the reabsorption of sodium and chloride in Henle's loop.
Which of the following actions by the nurse is most important when caring for a client with renal disease? a. Identify medications that have the potential for nephrotoxicity. b. Check the specific gravity of the urine daily. c. Eliminate potassium-rich foods from the diet. d. Encourage the client to void every four hours.
Answer: a. Identify medications that have the potential for nephrotoxicity. Rationale: Since the kidneys excrete most drugs, clients with renal failure will need a significantly lower dosage in order to avoid fatal consequences.
The client admitted for congestive heart failure (CHF) is receiving digoxin (Lanoxin) and furosemide (Lasix). Which of the following laboratory findings should the nurse carefully monitor? a. Potassium b. Creatinine c. Calcium d. Sodium
Answer: a. Potassium Rationale: Potassium loss is a serious side effect of loop diuretics, and this is a serious concern to clients being treated with digoxin (Lanoxin).
Administration of potassium supplements is contraindicated in clients taking which of the following diuretics? a. Spironolactone (Aldactone) b. Furosemide (Lasix) c. Chlorothiazide (Diuril) d. Bumetanide (Bumex)
Answer: a. Spironolactone (Aldactone) Rationale: Unlike with loop and thiazide diuretics, clients taking potassium-sparing diuretics should not take potassium supplements, due to the increased risk of hyperkalemia.
Which of the following actions is dependent upon proper functioning of the kidneys or the administration of Epogen? a. Stimulates the production of RBCs. b. Inhibits the release of renin. c. Detoxifies drugs in the bloodstream. d. Secretes the hormone cortisol.
Answer: a. Stimulates the production of RBCs. Rationale: The kidney is responsible for the hormone erythropoietin, which stimulates the production of RBCs.
Client education as relates to loop diuretics should include goals of therapy and should include which of the following points? (Select all that apply.) a. Take in the morning to avoid nighttime urination that could result in increased risk of injury. b. Expect decreased urine output. c. Take potassium supplements, if ordered, and eat potassium-rich foods. d. Check weight daily, and report a weight gain of 2 pounds or greater in 24 hours. e. Report any change in hearing (deafness).
Answer: a. Take in the morning to avoid nighttime urination that could result in increased risk of injury.; c. Take potassium supplements, if ordered, and eat potassium-rich foods.; d. Check weight daily, and report a weight gain of 2 pounds or greater in 24 hours.; e. Report any change in hearing (deafness). Rationale: Client education should include reasons for obtaining baseline data such as vital signs and tests for renal disorders, and possible side effects.
Which of the following problems is most often associated with myelomeningocele? A. Biliary atresia B. Hydrocephalus C. Craniosynostosis D. Tracheoesophageal fistula
Answer: b. Hydrocephalus is a frequently associated anomaly in 80% to 90% of children.
Which of the following is an important point of emphasis the nurse should include when teaching a client with diabetes regarding thiazides? a. Hypocalcemia b. Hyperglycemia c. Urinary tract infections d. Anemia
Answer: b. Hyperglycemia Rationale: Some thiazide diuretics can cause hyperglycemia and glycosuria in diabetic patients. Thiazides do not affect calcium or red blood cell levels.
Which of the following clinical manifestations of developmental dysplasia of the hip would be seen in the newborn? A. Lordosis B. Ortolani sign C. Trendelenburg sign D. Telescoping of the affected limb
Answer: b. In the newborn period, the dysplasia usually appears as hip joint laxity. During the Ortolani test, the examiner places forward pressure and then backward pressure on the trochanter. If the femoral head is felt to slip, dysplasia may be present. This test is most reliable from birth to 2 to 3 months.
For which of the following disorders should the nurse assess before administering chlorothiazide (Diuril)? a. Chronic urinary tract infections b. Low blood pressure c. Congenital malformations d. Hyperkalemia
Answer: b. Low blood pressure Rationale: Thiazide diuretics reduce circulating blood volume, which can cause orthostatic hypotension.
Which of the following is the most important baseline value prior to initiation of diuretic therapy? a. Glucose level b. Amino acids c. Blood pressure d. Sodium bicarbonate
Answer: c. Blood pressure Rationale: Although many baseline values are important, blood pressure (sitting and supine) can indicate excessive diuresis, which can result in dehydration and hypovolemia.
Which of the following clinical manifestations might indicate that the client has excessive potassium loss? a. Hypertension; angina b. Excessive thirst; urination c. Low blood pressure; cardiac arrhythmias d. Pitting edema; weight gain
Answer: c. Low blood pressure; cardiac arrhythmias Rationale: Rapid excretion of large amounts of fluid predisposes the client to potassium deficits and is manifested by hypotension, dizziness, cardiac arrhythmias, and fainting.
A newborn with congenital clubfoot is being treated with successive casts. The parents ask why so many casts are required. The nurse should explain that: A. casts are needed for the traction. B. each cast is good for only 6 weeks. C. surgical intervention will not be necessary. D. They allow for gradual stretching of tight structures.
Answer: d. Serial casting is begun shortly after birth and before discharge from nursery. Successive casts allow for gradual stretching of skin and tight structures on the medial side of the foot. Manipulation and casting of the leg are repeated frequently (every week) to accommodate the rapid growth of early infancy.
While assessing the newborn infant, the nurse notices a dimple with a tuft of hair at the bottom of the spine. What is the nurse's priority action? a) Place the child in the prone position to protect the area b) Soak a sterile dressing and place it over the area c) Notify the physician d) Educate the family on what this means for the child
Answer: d. it would be important to educate the family on the presence of spina bifida occulta, a neural tube defect that typically is benign and is often considered a normal defect. It would be important to differentiate this form of spina bifida from the highly stigmatized forms of spina bifida such as myelomingocele.
A client with a history of HF will be started on spironolactone (Aldactone). Which of the following drug groups should not be used, or used with extreme caution in patients taking potassium-sparing diuretics? 1. NSAIDs 2. Corticosteroids 3. Loop diuretics 4. ACE inhibitors or ARBs
Answer:4 Rationale: ACE inhibitors and ARBs taken concurrently with potassium -sparing diuretics increase the risk of hyperkalemia. Options 1,2, and 3 are incorrect. NSAIDs are used cautiously with all diuretics because they are excreted through the kidney. Corticosteroids and loop diuretics may cause hypokalemia and may be paired with a potassium -sparing diuretic to reduce the risk of hypokalemia developing if a diuretic is needed.

The nurse providing discharge teaching for a client recently started on a tricyclic antidepressant (TCA) must include the importance of: Avoiding driving or operating dangerous equipment. Using sugarless gum for a dry mouth. Taking medication with meals. Increasing fluid intake.
Avoiding driving or operating dangerous equipment. Objective: Use the nursing process to care for clients receiving drug therapy for mood and emotional disorders. Rationale: Safety is always the first priority for nurses to address. Sedation is frequently reported at initiation of therapy, and safety needs are of highest priority. The other options should also be included in the teaching, but are not the most important. Cognitive Level: Application Client Need: Physiological Integrity: Pharmacological and Parenteral Therapies Nursing Process: Implementation
A patient with chronic congestive heart failure has repeated hospitalizations in spite of ongoing treatment with hydrochlorothiazide [HydroDIURIL] and digoxin. The prescriber has ordered spironolactone [Aldactone] to be added to this patient's drug regimen, and the nurse provides education about this medication. Which statement by the patient indicates understanding of the teaching? a. "I can expect improvement within a few hours after taking this drug." b. "I need to stop taking potassium supplements." c. "I should use salt substitutes to prevent toxic side effects." d. "I should watch closely for dehydration."
B Spironolactone is a potassium-sparing diuretic used to counter the potassium-wasting effects of hydrochlorothiazides. Patients taking potassium supplements are at risk for hyperkalemia when taking this medication, so they should be advised to stop the supplements. Spironolactone takes up to 48 hours to have effects. Salt substitutes contain high levels of potassium and are contraindicated. Spironolactone is a weak diuretic, so the risk of dehydration is not increased.
The nurse knows that which of the following are major disadvantages for the use of donepezil (Aricept) to treat the symptoms of early Alzheimer's disease? (Select all that apply.) A. It must be administered four times per day. B. It may causes significant weight loss. C. It may cause potentially fatal cardiac dysrhythmias. D. It may cause serious hepatic damage. E. It results in only modest cognitive improvement and results do not last.
B, C, D, E. Donepezil (Aricept) may cause serious liver damage and potentially fatal dysrhythmias including severe bradycardia and heart block. It may also cause significant weight loss, and the patient's weight should be monitored. While cognitive improvement may be observed in as few as 1 to 4 weeks, patients should receive pharmacotherapy for at least 6 months prior to assessing maximum benefits of drug therapy. Unfortunately, cognitive improvement is only modest and short-term. Option A is incorrect. Donepezil is taken once per day usually at bedtime.
The teaching plan for a 24-year-old female who is receiving tretinoin (Avita, Retin-A, Trentin-X) for treatment of acne should include which of the following instructions? (Select all that apply.) A: Obtain 20 to 30 minutes of sun exposure per day to help dry the skin and prevent breakouts. B: Wash the face with a mild soap, avoiding scrubbing, twice a day. C: Use oil-free sunscreens, sun hats, and protective clothing to avoid sun exposure. D: Expect some dryness, redness, and peeling while on the drug but report severe skin irritation. E: Cover the area with a light dressing covered in plastic wrap to prevent the cream from rubbing off.
B, C, D. Washing the face gently with a mild soap and using sunscreens and protection from sun exposure are part of the care required for patients who are taking tretinoin. Mild dryness, redness, and peeling skin are all possible adverse effects that are expected. Any severe skin irritation or pain should be reported. Options A and E are incorrect. Sun exposure should be avoided unless specifically instructed to do so by the health care provider. The heat trapped by the plastic wrap may exacerbate the acne.
A nurse is planning care for a patient who takes fexofenadine (Allegra) for allergic rhinitis. Which outcome should the nurse anticipate? A. No complaints of dry mouth B. Relief of sneezing and itching C. Use limited to allergy season D. Absence of rebound congestion
B. Fexofenadine, a second-generation antihistamine, is prescribed as a first-line medication for allergic rhinitis to relieve sneezing, rhinorrhea, and nasal itching. Anticholinergic effects (dry mouth, constipation) are uncommon with second-generation antihistamines. Antihistamines are most effective when taken prophylactically. Rebound congestion develops in topical sympathomimetic agents.
Which statement by a patient indicates understanding of a nurse's teaching about fluticasone nasal spray (Flonase)? A. "I'll gradually stop taking this so I don't have any problems with withdrawal." B. "This drug will help prevent the inflammation and irritation from my allergies." C. "I'll have to be more careful about not falling, because my bones may break more easily." D. "I realize that I only need to take this when my symptoms are really bad."
B. Fluticasone nasal spray is a steroid drug used to prevent the symptoms of allergy. Its effect is localized; therefore, the patient does not have systemic adverse effects with normal use and does not have to wean down the medication, as with oral corticosteroids. Intranasal glucocorticoids are most effective for preventing and treating allergic rhinitis.
Which instruction should the nurse include in the teaching for a patient prescribed cetirizine (Zyrtec) for seasonal allergic rhinitis? A. "Clean the nasal applicator after use to prevent contamination." B. "Take the medication daily throughout the allergy season." C. "Expect a decrease in your nasal congestion in a day or two." D. "Take a stool softener daily to avoid the side effect of constipation."
B. For treatment of allergic rhinitis, antihistamines such as cetirizine are most effective when taken prophylactically throughout the allergy season, even when symptoms are absent. The medication is taken orally, not intranasally. Oral antihistamines relieve sneezing, rhinorrhea, and nasal itching but not nasal congestion. Constipation is rare in patients taking second-generation agents, such as cetirizine.
Which complaint indicates that a patient is experiencing an adverse effect of beclomethasone (Beconase AQ) nasal spray? A. Sneezing B. Sore throat C. Runny nose D. Rebound congestion
B. Sore throat is an adverse effect associated with intranasal glucocorticoids, such as beclomethasone. More common adverse effects include drying of the nasal mucosa and a burning or itching sensation. Sneezing and runny nose are two of the symptoms of allergic rhinitis for which intranasal glucocorticoids are used. Rebound congestion is an adverse effect of intranasal sympathomimetics.
A nurse should recognize that recent research has shown which statement is true about the use of zinc in children with colds? A. Efficacy is seen within the first 24 hours of signs and symptoms. B. Evidence has been inconclusive, and more research is needed. C. Lozenges with the lemon-lime formula are the most effective. D. Recovery is accelerated, and symptoms resolve quickly.
B. Studies have shown that zinc can benefit adults with colds. However, the one study done in children showed no beneficial effects. The study left unanswered questions; therefore, more research is required. Conclusions about efficacy, lozenge formula, and time to recovery are open to other possible interpretations in the one study done in children.
The patient is receiving Phenobarbital (Luminal) for control of seizures. The patient tells the nurse she plans to become pregnant. What is the best response of the nurse? Select one: A. "Your medication dose will need to be increased during your pregnancy." B. "Please talk to your doctor; this drug is contraindicated in pregnancy." C. "Please talk to your doctor; you will need a safer drug like valproic acid (Depakene)." D. "Your medication dose will need to be decreased during your pregnancy."
B. "Please talk to your doctor; this drug is contraindicated in pregnancy."
The client receives albuterol (Proventil) via inhaler. He asks the nurse why he can't just take a pill. What is the best response by the nurse? Select one: A. "Because pills would produce too many side effects; you will have very few side effects with inhaled medications." B. "When you inhale the drug the blood supply in your lungs picks it up rapidly, resulting in quicker effects." C. "Because this medication cannot be absorbed from your GI tract; the acid in your stomach would destroy it." D. "Because pills cannot help your illness; you must have inhaled medications for relief of symptoms."
B. "When you inhale the drug the blood supply in your lungs picks it up rapidly, resulting in quicker effects."
A patient receiving phenytoin (Dilantin) has a serum drug level drawn. Which level will the nurse note as therapeutic? A. 6 mcg/mL B. 12 mcg/mL C. 8 mcg/mL D. 30 mcg/mL
B. 12 mcg/mL
A patient has started clopidogrel (Plavix) after experiencing a transient ischemic attack. What is the desired therapeutic effect of this drug? A: Anti-inflammatory and antipyretic effects B: To reduce the risk of a stroke from a blood clot C: Analgesic as well as clot-dissolving effects D: To stop clots from becoming emboli
B. Antiplatelet drugs such as clopidogrel are given to inhibit platelet aggregation and, thus, reduce the risk of thrombus formation. Options A, C, and D are incorrect. Antiplatelet drugs do not exert anti-inflammatory, antipyretic, or analgesic effects. The antiplatelet and anticoagulant drugs do not prevent emboli formation. Thrombolytics dissolve existing blood clots.
An 8-year-old boy is evaluated and diagnosed with absence seizures. He is started on ethosuximide (Zarontin). Which information should the nurse provide the parents? A. After-school sports activities will need to be stopped because they will increase the risk of seizures. B. Monitor height and weight to assess that growth is progressing normally. C. Fractures may occur, so increase the amount of vitamin D and calcium-rich foods in the diet. D. Avoid dehydration with activities and increase fluid intake.
B. Because adverse drug effects such as nausea, anorexia, or abdominal pain may occur with ethosuximide (Zarontin), the parents should monitor the child's height and weight to assess whether nutritional intake is sufficient for normal growth and development. Options A, C, and D are incorrect. Physical activity does not increase the risk of seizure activity or need to be curtailed, and the drug does not affect bone growth or require extra vitamin D or calcium in the diet. Dehydration is a condition to be avoided in all clients, although increasing fluid intake is not necessarily related to the use of ethosuximide.
Which food items should the nurse advise a patient taking a monoamine oxidase inhibitor (MAOI) to avoid? Select one: A. Orange juice, cottage cheese, and turkey B. Chocolate, wine, and fava beans C. Spring water, ice cream, and salmon D. Spinach, rice, and venison
B. Chocolate, wine, and fava beans
Exposure to perfume, cosmetics, detergents, or latex is associated with which of the following disorders? A. Atopic dermatitis B. Contact dermatitis C. Seborrheic dermatitis D. Stasis dermatitis
B. Contact dermatitis
Which vitamin is synthesized by the skin? A. A B. D C. E D. K
B. D
A 17-year-old patient has been prescribed escitalopram (Lexapro) for increasing anxiety uncontrolled by other treatment measures. Because of this patient's age, the nurse will ensure that the patient and parents are taught what important information? A. Cigarette smoking will counteract the effects of the drug. B. Signs of increasing depression or thoughts of suicide should be reported immediately. C. The drug causes dizziness and alternative schooling arrangements may be needed for the first two months of use. D. Anxiety and excitability may increase during the first two weeks of use but then will have significant improvement.
B. Escitalopram (Lexapro) is an antidepressant in the SSRI class. The drug carries a black box warning of increased risk of suicidal thinking and behavior in children, adolescents, and young adults. Signs of increasing depression or suicidal thoughts should be reported immediately. Options A, C, and D are incorrect. Smoking has no direct effects on escitalopram. Although dizziness may occur, it should not be significant enough to warrant a change in schooling needs. Escitalopram should not cause increased anxiety or excitability in the first few weeks of use, and other causes should be investigated should these occur.
The nurse discusses the disease process of multiple sclerosis with the patient and caregiver. The patient will begin taking glatiramer (Copaxone), and the nurse is teaching the patient about the drug. Which of the following points should be included? A. Drink extra fluids while this drug is given. B. Local injection site irritation is a common effect. C. Take the drug with plenty of water and remain in an upright position for at least 30 minutes. D. The drug causes a loss of vitamin C so include extra citrus and foods containing vitamin C in the diet.
B. Glatiramer (Copaxone) is given by injection and often causes injection site irritation. Options A, C, and D are incorrect. Extra fluids do not need to be included and the drug is not given orally. It does not deplete vitamin C from the body.
The nurse is providing teaching to a patient who has been prescribed furosemide (Lasix). Which of the following should the nurse teach the patient? A: Avoid consuming large amounts of kale, cauliflower, or cabbage. B: Rise slowly from a lying or sitting position to standing. C: Count the pulse for one full minute before taking this medication. D: Restrict fluid intake to no more than 1 L per 24-hour period.
B. Loop diuretics such as furosemide (Lasix) may dramatically reduce a patient's circulating blood volume from diuresis and may cause orthostatic hypotension. To minimize the chance for syncope and falls, the patient should be taught to rise slowly from a lying or sitting position to standing. Options A, C, and D are incorrect. Kale, cauliflower, and cabbage contain vitamin K, which does not need to be restricted during diuretic therapy. Monitoring the pulse along with the blood pressure to assess for reflex tachycardia is advised, but the pulse does not need to be taken for one full minute before taking the drug. Fluids should not be restricted during diuretic therapy unless ordered by the provider.
A patient has been taking phenytoin (Dilantin) for control of generalized seizures, tonic-clonic type. The patient is admitted to the medical unit with symptoms of nystagmus, confusion, and ataxia. What change in the phenytoin dosage does the nurse anticipate will be made based on these symptoms? A. The dosage will be increased. B. The dosage will be decreased. C. The dosage will remain unchanged; these are symptoms unrelated to the phenytoin. D. The dosage will remain unchanged but an additional antiseizure medication may be added.
B. Nystagmus, confusion, and ataxia may occur with phenytoin, particularly with higher dosages. The dosage is likely to be decreased. Options A, C, and D are incorrect. The dosage would not remain the same or be increased because these are adverse effects of phenytoin that are related to overdosage.
The patient asks what can be expected from the levodopa/carbidopa (Sinemet) he is taking for treatment of Parkinson's Disease. What is the best response by the nurse? A. "A cure can be expected within 6 months." B. "Symptoms can be reduced and the ability to perform ADLs can be improved." C. "Disease progression will be stopped." D. "Extrapyramidal symptoms will be prevented."
B. Pharmacotherapy does not cure or stop the disease process but does improve the patient's ability to perform ADLs such as eating, bathing, and walking. Options A, C, and D are incorrect. Drug therapy for PD does not cure or halt progression of the disease. Depending on the drug therapy, EPS may be an adverse effect.
Methotrexate (Rheumatrx, Trexall) may be used to treat psoriasis. Which other condition is it used for? A. Gout and rheumatoid arthritis B. Rheumatoid arthritis and certain cancers C. Systemic fungal infections and certain cancers D. Urinary tract infections and peptic ulcers
B. Rheumatoid arthritis and certain cancers
Topical corticosteroids are a common treatment for all of the following EXCEPT: A. Psoriasis B. Rosacea C. Pruritus D. Dermatitis
B. Rosacea
The nurse is caring for a 34-year-old male patient who sustained a deep partial thickness burn to the anterior chest area during a workplace accident 6 hours ago. Which assessment findings would the nurse identify as congruent with this type of burn? A. Skin is hard with a dry, waxy white appearance. B. Skin is shiny and red with clear, fluid-filled blisters. C. Skin is red and blanches when slight pressure is applied. D. Skin is leathery with visible muscles, tendons, and bones.
B. Skin is shiny and red with clear, fluid-filled blisters. Deep partial thickness burns have fluid-filled vesicles that are red and shiny. They may appear wet (if vesicles have ruptured), and mild to moderate edema may be present. Superficial partial thickness burns are red and blanch with pressure vesicles that appear 24 hours after the burn injury. Full-thickness burns are dry, waxy white, leathery, or hard, and there may be involvement of muscles, tendons, and bones.
Matching: Benzocaine (Solarcaine) A. Scabicide/pediculicide B. Sunburn/minor irritation drug C. Acne and acne-related drug D. Topical corticosteroid E. Psoriatic drug
B. Sunburn/minor irritation drug
Which of the following medications is also used for the treatment of wrinkles? A. Benzoyl peroxide (Clearasil, Fostex, others) B. Tretinoin (Avita, Retin-A, others) C. Calcipotriene (Dovonex) D. Hydroxyurea (Hydrea)
B. Tretinoin (Avita, Retin-A, others)
Matching: Closed comedones A. Black head B. Whiteheads C. Intense itching D. Redness E. "First-degree" injury
B. Whiteheads
Oral decongestants differ from intranasal decongestants in that oral decongestants Select one: A. can cause rebound congestion. B. have more systemic effects. C. are more effective at relieving severe congestion. D. have high efficacy.
B. have more systemic effects.
The patient receiving heparin therapy asks how the "blood thinner" works. What is the best response by the nurse? A: "Heparin makes the blood less thick." B: "Heparin does not thin the blood but prevents clots from forming as easily in the blood vessels." C: "Heparin decreases the number of platelets so that blood clots more slowly." D: "Heparin dissolves the clot."
B: Anticoagulants do not change the viscosity (thickness) of the blood. Instead, anticoagulants modify the mechanisms by which clotting occurs. Options A, C, and D are incorrect. Heparin does not make the blood less viscous or actually thinner and does not decrease the number of platelets or dissolve existing clots.
A 15-year-old patient started using topical benzoyl peroxide (Benzaclin, Fostex) 1 week ago for treatment of acne and is discouraged that her acne is still visible. What is the nurse's best response? A: "The cream should have started working by now. Check with your provider about switching to a different type." B: "Some improvement will be noticed quickly, but full effects may take several weeks to a month or longer." C: "Acne is very difficult to treat. It may be several months before you notice any effects." D: "If your acne is not gone by now, you may need an antibiotic too. Ask your provider."
B: Initial drying of the skin caused by benzoyl peroxide will help begin to clear acne lesions in the early stages of treatment, but it may take several weeks before full effects are visible. Options A, C, and D are incorrect. One week of keratolytic therapy for acne should demonstrate the beginning of therapeutic effects. Most acne is responsive to keratolytic therapy but may need an antibiotic included as part of the treatment plan after a full course of the keratolytic has been tried. Only in severe cases is oral drug therapy usually considered after other treatment options have not been successful.
A patient has been prescribed fluticasone (Flonase) to use with oxymetazoline (Afrin). How should the patient be taught to use these drugs? A: Use the fluticasone first, then the oxymetazoline after waiting 5 minutes. B: Use the oxymetazoline first, then the fluticasone after waiting 5 minutes. C: The drugs may be used in either order. D: The fluticasone should be used only if the oxymetazoline fails to relieve the nasal congestion.
B: The oxymetazoline (Afrin) should be used first, followed by the fluticasone (Flonase) in 5 to 10 minutes. When a decongestant and corticosteroid nasal spray are used together, the decongestant spray should be used first to allow time for the nasal passages to open, allowing the corticosteroid to reach deeper into the nasal passages. Options A, C, and D are incorrect. The drugs are ordered in combination for better control of nasal rhinitis. The oxymetazoline should not be used for over 5 days unless otherwise directed.
The patient is treated for head lice with permethrin (Nix). Following treatment, the nurse will reinforce which of the following instructions? A: Remain isolated for 48 hours. B: Inspect the hair shafts, checking for nits daily for 1 week following treatment. C: Shampoo with permethrin three times per day. D: Wash linens with cold water and bleach.
B: To ensure the effectiveness of drug therapy, patients should inspect hair shafts after treatment, checking for nits by combing with a fine-toothed comb after the hair is dry. This procedure must be conducted daily for at least 1 week after treatment. Options A, C, and D are incorrect. The patient does not require isolation, and permethrin solution is applied once and allowed to remain in the hair for approximately 10 minutes. Linens should be washed with hot water; bleach is not required.
Emergent resuscitative phase
Begins with fluid loss and edema formation at time of burn *greatest threat is hypovolemic shock- BP decreases, HR increases, U/O decreased Continues until fluid mobilization and diuresis occurs ABCs are the priority Can last 48 hours to several days
Acute phase of the burn
Begins with mobilization of fluid (= diuresis) and ends when burned area is completely covered or healed Highest risk of infection in this stage Can last 48 hours, weeks or months

A patient is taking gentamicin [Garamycin] and furosemide [Lasix]. The nurse should counsel this patient to report which symptom? a. Frequent nocturia b. Headaches c. Ringing in the ears d. Urinary retention
C Patients taking furosemide should be advised that the risk of furosemide-induced hearing loss can be increased when other ototoxic drugs, such as gentamicin, are also taken. Patients should be told to report tinnitus, dizziness, or hearing loss. Nocturia may be an expected effect of furosemide. Headaches are not likely to occur with concomitant use of gentamicin and furosemide. Urinary retention is not an expected side effect.
A patient has 2+ pitting edema of the lower extremities bilaterally. Auscultation of the lungs reveals crackles bilaterally, and the serum potassium level is 6 mEq/L. Which diuretic agent ordered by the prescriber should the nurse question? a. Bumetanide [Bumex] b. Furosemide [Lasix] c. Spironolactone [Aldactone] d. Hydrochlorothiazide [HydroDIURIL]
C Spironolactone is a non-potassium-wasting diuretic; therefore, if the patient has a serum potassium level of 6 mEq/L, indicating hyperkalemia, an order for this drug should be questioned. Bumetanide, furosemide, and hydrochlorothiazide are potassium-wasting diuretics and would be appropriate to administer in a patient with hyperkalemia.
A patient who is taking digoxin is admitted to the hospital for treatment of congestive heart failure. The prescriber has ordered furosemide [Lasix]. The nurse notes an irregular heart rate of 86 beats per minute, a respiratory rate of 22 breaths per minute, and a blood pressure of 130/82 mm Hg. The nurse auscultates crackles in both lungs. Which laboratory value causes the nurse the most concern? a. Blood glucose level of 120 mg/dL b. Oxygen saturation of 90% c. Potassium level of 3.5 mEq/L d. Sodium level of 140 mEq/L
C This patient has an irregular, rapid heartbeat that might be caused by a dysrhythmia. This patient's serum potassium level is low, which can trigger fatal dysrhythmias, especially in patients taking digoxin. Furosemide contributes to loss of potassium through its effects on the distal nephron. Potassium-sparing diuretics often are used in conjunction with furosemide to prevent this complication. This patient's serum glucose and sodium levels are normal and of no concern at this point, although they can be affected by furosemide. The oxygen saturation is somewhat low and needs to be monitored, although it may improve with diuresis.
Which of the following is among the first-choice drugs used for allergic rhinitis? A. Nonsteroidal anti-inflammatory drugs (NSAIDs) B. Sympathomimetics C. Glucocorticoids D. Cytokines
C. Glucocorticoids
Antihistamines block the actions of histamine at the Select one: A. B2 receptor site. B. B1 receptor site. C. H1 receptor site. D. C1 receptor site.
C. H1 receptor site.
A patient has a prescription for fluticasone (Flonase). Place the following instructions in the order in which the nurse will instruct the patient to use the drug. A: Instill one spray directed high into the nasal cavity. B: Clear the nose by blowing. C: Prime the inhaler prior to first use. D: Spit out any excess liquid that drains into the mouth.
C, B, A, D. When an intranasal inhaler is used, the device should be primed prior to the first use; the nasal passages should be cleared by blowing; the drug should be instilled by spray directed high into the nasal passages; and any liquid that drains into the mouth should be spit out.
The patient admitted for heart failure has been receiving hydrochlorothiazide (Microzide). Which of the following laboratory levels should the nurse carefully monitor? (Select all that apply.) A: Platelet count B: White blood cell count C: Potassium D: Sodium E: Uric acid
C, D, E. Thiazide diuretics such as hydrochlorothiazide (Microzide) cause loss of sodium and potassium and may cause hyperuricemia. Options A and B are incorrect. Hydrochlorothiazide does not have a direct effect on blood cells.
Zolpidem (Ambien, Edluar, Intermezzo) has been ordered for a patient for the treatment of insomnia. What information will the nurse provide for this patient? (Select all that apply.) A. Be cautious when performing morning activities because it may cause a significant "hangover" effect with drowsiness and dizziness. B. Take the drug with food; this enhances the absorption for quicker effects. C. Take the drug immediately before going to bed; it has a quick onset of action. D. If the insomnia is long-lasting, this drug may safely be used for up to one year. E. Alcohol and other drugs that cause CNS depression (e.g., antihistamines) should be avoided while taking this drug.
C, E. Zolpidem (Ambien, Intermezzo) has a rapid onset, approximately 7 to 27 minutes, and should be taken immediately before going to bed. It should not be taken with alcohol or other drugs that cause CNS depression because of increased sedation and CNS depression. Options A, B, and D are incorrect. Taking the drug with food will significantly impair its absorption and the onset of action may be delayed. Zolpidem has a duration of action of approximately 6 to 8 hours. Depending on when the drug is taken the night before, significant "hangover" effects such as sedation are not as likely to occur as with other drugs in the category. The drug is approved for short-term treatment of insomnia only.
Which outcome would be most appropriate for a nurse to establish for a patient with a cough who takes an antitussive with codeine? A. Warm, dry, pink skin B. Oriented to time, place, and person C. Respiratory rate of 12 to 24 breaths per minute D. Effective productive cough
C. Codeine, an opioid analgesic that acts through the CNS, effectively suppresses the frequency and intensity of cough. However, it also can suppress respiration, and overdose can be fatal. Doses are small (one-tenth those needed to relieve pain), so orientation and peripheral effects are minimal.
Which instruction by the nurse should be the priority for a patient scheduled to start intranasal cromolyn (NasalCrom)? A. "It is only moderately effective." B. "There are few adverse reactions." C. "Relief may take a week or two." D. "It suppresses histamine release."
C. Cromolyn is best suited for prophylaxis and should be given before symptoms start, because responses may take a week or 2 to develop. It is important for the patient to know about cromolyn's moderate effectiveness, few adverse reactions, and suppression of histamine release, but it is more important that the patient be informed of the delay in response.
A nurse instructs a patient that which nonprescription medication requires patient identification and a signature for purchase? A. Chlorpheniramine (Chlor-Trimeton) B. Cetirizine (Zyrtec) C. Ephedrine D. Ipratropium bromide (Atrovent)
C. Ephedrine is a sympathomimetic agent associated with abuse, because it can be converted to methamphetamine. Legal availability has been reduced by having the product behind the counter, and patients must present identification and sign a log for purchase. Chlorpheniramine and cetirizine are first- and second-generation antihistamines that are available without legal constraints. Ipratropium bromide, an anticholinergic intranasal agent for allergic rhinitis, also does not require patient identification.
A nurse is teaching a patient who is to start taking an expectorant. The nurse provides the patient with which of these instructions? A. "Restrict cold fluids to promote reduced mucus production." B. "Take the medication once a day only, usually at bedtime." C. "Increase your fluid intake to reduce the viscosity of secretions." D. "Increase your fiber and fluid intake to prevent constipation."
C. Expectorant drugs are used to reduce the viscosity of secretions, allowing them to be more easily expectorated. Reduction of mucus production is unrelated to an expectorant. Expectorants may be taken several times a day and do not cause constipation.
Which finding in a patient taking oxymetazoline (Afrin) nasal spray every 2 hours would indicate that the patient has developed an adverse effect? A. Dry mouth and constipation B. Drowsiness and sedation C. Congestion and stuffiness D. Itching and skin rash
C. Oxymetazoline is an effective nasal decongestant, but overuse results in worsening, or rebound, congestion. It should not be used more often than every 4 hours for several days. Dry mouth and constipation, drowsiness and sedation, and itching and skin rash are not adverse effects of oxymetazoline.
Which instruction should be included in the teaching for a patient being started on the antihistamine azelastine (Astelin)? A. "Take the pill in the morning before breakfast." B. "Headache may be a side effect of the medication." C. "You may experience an unpleasant taste in your mouth when using azelastine." D. "You will experience a decrease in nasal congestion if the medication is working."
C. With both formulations of azelastine (Astelin and Astepro), patients often complain of an unpleasant taste. Azelastine is administered as an intranasal metered spray. Headache is a side effect of the intranasal antihistamine olopatadine. Antihistamines do not reduce nasal congestion.
The client tells the nurse that her symptoms have become worse since she has been using oxymetazoline (Afrin) for nasal congestion. What is the best assessment question for the nurse to ask? Select one: A. "How old is the bottle you are using?" B. "Are you using any other inhaled medications?" C. "How long have you been using the medication?" D. "May I take your temperature?"
C. "How long have you been using the medication?"
Which patient should the nurse prepare to transfer to a regional burn center? A. A 25-year-old pregnant patient with a carboxyhemoglobin level of 1.5% B. A 39-year-old patient with a partial-thickness burn to the right upper arm C. A 53-year-old patient with a chemical burn to the anterior chest and neck D. A 42-year-old patient who is scheduled for skin grafting of a burn wound
C. A 53-year-old patient with a chemical burn to the anterior chest and neck The American Burn Association (ABA) has established referral criteria to determine which burn injuries should be treated in burn centers where specialized facilities and personnel are available to handle this type of trauma (see Table 25-3). Patients with chemical burns should be referred to a burn center. A normal serum carboxyhemoglobin level for nonsmokers is 0% to 1.5% and for smokers is 4% to 9%. Skin grafting for burn wound management is not a criterion for a referral to a burn center. Partial-thickness burns greater than 10% total body surface area (TBSA) should be referred to a burn center. A burn to the right upper arm is 4% TBSA.
While obtaining a patient history, the nurse notes that the patient has been prescribed ethosuximide (Zarontin). The nurse suspects that the patient has which type of seizure? A. Partial B. Generalized C. Absence D. Tonic-clonic
C. Absence
Matching: Azelaic acid (Azelex) A. Scabicide/pediculicide B. Sunburn/minor irritation drug C. Acne and acne-related drug D. Topical corticosteroid E. Psoriatic drug
C. Acne and acne-related drug
Matching: Benzoyl peroxide (BenzaClin) A. Scabicide/pediculicide B. Sunburn/minor irritation drug C. Acne and acne-related drug D. Topical corticosteroid E. Psoriatic drug
C. Acne and acne-related drug
Matching: Sulfacetamide sodium (AK-Sulf) A. Scabicide/pediculicide B. Sunburn/minor irritation drug C. Acne and acne-related drug D. Topical corticosteroid E. Psoriatic drug
C. Acne and acne-related drug
The nurse should assess a patient who is taking lorazepam (Ativan) for the development of which of these adverse effects? A. Tachypnea B. Astigmatism C. Ataxia D. Euphoria
C. Adverse CNS effects for lorazepam (Ativan) include ataxia, amnesia, weakness, disorientation, blurred vision, diplopia, nausea, and vomiting. Options A, B, and D are incorrect. Lorazepam is not known to cause tachycardia, astigmatism, or euphoria. If these symptoms occur, the patient should be assessed for other causative factors.
Topical metronidazole (Metrogel, MetroCream) is used to treat rosacea. For which of the following options is it used when given PO or IV? A. Crohn's disease B. To decrease lipid levels in the blood C. Anti-infective therapy D. Dysrhythmias
C. Anti-infective therapy
Which of the following patient statements indicates that the levodopa/carbidopa (Sinemet) is effective? A. "I'm sleeping a lot more, especially during the day." B. "My appetite has improved." C. "I'm able to shower by myself." D. "My skin doesn't itch anymore."
C. Becoming more independent in ADLs shows an improvement in physical abilities. Options A, B, and D are incorrect. Drowsiness is a common adverse effect of medications for PD. Anorexia or loss of appetite is also a common adverse effect and skin itching is not related to medication use.
Which of the following is an over-the-counter (OTC) medication for acne? A. Adapalene (Differin) B. Azelaic acid (Azelex, Finacea, others) C. Benzoyl peroxide (Clearasil, Fostex, others) D. Sulfacetamide (Cetamide, Klaron, others)
C. Benzoyl peroxide (Clearasil, Fostex, others)
Which of the following drugs is most immediately helpful in treating a severe acute asthma attack? A. Beclomethasone (Qvar) B. Zileuton (Zyflo CR) C. Albuterol (Proventil, Ventolin) D. Salmeterol (Serevent Diskus)
C. Beta-adrenergic drugs such as albuterol (Proventil, Ventolin) are most often used for rapid bronchodilation. Options A, B, and D are incorrect. Corticosteroids such as beclomethasone, leukotriene modifiers such as zileuton, and LABAs such as salmeterol may be used for maintenance therapy to prevent or control asthma attacks but do not act quickly enough for acute attacks.
An early sign(s) of levodopa toxicity is (are) which of the following? A. Orthostatic hypotension B. Drooling C. Spasmodic eye winking and muscle twitching D. Nausea, vomiting, and diarrhea
C. Blepharospasm (spasmodic eye winking) and muscle twitching are early signs of potential overdose or toxicity. Options A, B, and D are incorrect. Orthostatic hypotension is a common adverse effect of both PD and many drugs used to treat the condition but is not a symptom of overdosage or toxicity. Drooling, nausea, vomiting, and diarrhea are also not symptoms of overdose or toxicity.
The nurse is caring for a postoperative craniotomy patient. Which prescribed drug does the nurse make sure is readily available to treat acute seizure activity? A. Flumazenil (Romazicon) B. Gabapentin (Neurontin) C. Diazepam (Valium) D. Ethosuximide (Zarontin)
C. Diazepam (Valium)
Matching: Pruritus A. Black head B. Whiteheads C. Intense itching D. Redness E. "First-degree" injury
C. Intense itching
A patient who received a prescription for montelukast (Singulair) returns to his provider's office after three days, complaining that "the drug is not working." She reports mild but continued dyspnea and has had to maintain consistent use of her bronchodilator inhaler, albuterol (Proventil). What does the nurse suspect is the cause of the failure of the montelukast? A. The patient is not taking the drug correctly. B. The patient is not responding to the drug and will need to be switched to another formulation. C. The drug has not had sufficient time of use to have full effects. D. The albuterol inhaler is interacting with the montelukast.
C. Leukotriene modifiers such as montelukast (Singulair) take up to 1 week or longer to develop full effects. The patient should continue to use her bronchodilator as needed while the drug reaches full therapeutic effects. If no change in effects is noted after 7-10 days, the therapy should be re-evaluated. Options A, B, and D are incorrect. Because the drug is taken PO, the patient should be self-administering the montelukast correctly. More time is needed before determining whether the drug will have full effects, and it is often used as an adjunct to bronchodilation therapy.
The parents of a young patient receiving methylphenidate (Ritalin) express concern that the health care provider has suggested the child have a "holiday" from the drug. What is the purpose of a drug-free period? A. To reduce or eliminate the risk of drug toxicity B. To allow the child's "normal" behavior to return C. To decrease drug dependence and assess the patient's status D. To prevent the occurrence of a hypertensive crisis
C. Methylphenidate (Ritalin) is a Schedule II drug with potential to cause drug dependence when used over an extended period. The drug holiday helps to decrease the risk of dependence. It is also useful to evaluate current behavior; if improvement is noted, the drug dosage may be lowered or the drug stopped. Options A, B, and D are incorrect. Brief holidays off the medication will not eliminate the risk of toxicity. Toxicity may still occur while the patient takes the medication. The child's "normal" behavior may have been the reason for medication therapy. Hypertension may occur from methylphenidate but, except in the case of an overdose, should not reach a crisis level.
Which of the following clinical manifestations may indicate that the patient taking metolazone (Zaroxolyn) is experiencing hypokalemia? A: Hypertension B: Polydipsia C: Cardiac dysrhythmias D: Skin rash
C. Metolazone (Zaroxolyn) is a thiazide diuretic and causes potassium loss. Signs of hypokalemia include cardiac dysrhythmias, hypotension, dizziness, and syncope. Options A, B, and D are incorrect. Polydipsia is not associated with hypokalemia. HTN is a clinical indication for the use of diuretics. Skin rashes are an adverse effect of metolazone but are not a symptom of hypokalemia.
While planning for a patient's discharge from the hospital, which of the following teaching points would be included for a patient going home with a prescription for chlorothiazide (Diuril)? A: Increase fluid and salt intake to make up for the losses caused by the drug. B: Increase intake of vitamin-C rich foods such as grapefruit and oranges. C: Report muscle cramping or weakness to the health care provider. D: Take the drug at night because it may cause drowsiness.
C. Muscle cramping or weakness may indicate hypokalemia and should be reported to the health care provider. Options A, B, and D are incorrect. Patients on diuretic therapy are taught to monitor sodium (salt) and water intake to maintain adequate, but not excessive, amounts. Vitamin C-rich foods do not need to be increased while a patient is taking chlorothiazide. The drug should be taken early in the day to avoid nocturia. It does not cause drowsiness.
Which of the following would be a priority component of the teaching plan for a patient prescribed phenelzine (Nardil) for treatment of depression? A. Headaches may occur. Over-the-counter medications will usually be effective. B. Hyperglycemia may occur and any unusual thirst, hunger, or urination should be reported. C. Read labels of food and over-the-counter drugs to avoid those with substances that should be avoided as directed. D. Monitor blood pressure for hypotension and report any blood pressure below 90/60.
C. Phenelzine (Nardil) is an MAOI. This class of drugs has many drug and food interactions that may cause a hypertensive crisis. A list of foods, beverages, and medications to avoid should also be given to the patient. Options A, B, and D are incorrect. Headaches, especially if severe, may signal the beginning of a hypertensive crisis and any severe or increasing headache should be reported immediately. MAOIs are not known to cause hyperglycemia and other causes should be investigated if it occurs. The use of CNS depressants, including narcotics, along with an MAOI may cause profound hypotension, but the risk of hypertensive crisis is much greater and would have priority for teaching.
The nurse determines that the teaching plan for a patient prescribed sertraline (Zoloft) has been effective when the patient makes which statement? A. "I should not decrease my sodium or water intake." B. "The drug can be taken concurrently with the phenelzine (Nardil) that I'm taking." C. "It may take up to a month for the drug to reach full therapeutic effects and I'm feeling better." D. "There are no other drugs I need to worry about; Zoloft doesn't react with them."
C. SSRI antidepressant drugs such as sertraline (Zoloft) may not have full effects for a month or longer, but some improvement in mood and depression should be noticeable after beginning therapy. Options A, B, and D are incorrect. Sodium and fluid intake is a concern with lithium but does not adversely affect the SSRIs. The SSRIs should not be used concurrently with MAOIs because of an increased risk of hypertensive crisis. They also have many interactions with other drugs.
Drugs to treat oily skin would most likely be used for which of the following disorders? A. Atopic dermatitis B. Contact dermatitis C. Seborrheic dermatitis D. Stasis dermatitis
C. Seborrheic dermatitis
A 77-year-old female patient is diagnosed with depression and anxiety and is started on imipramine. Because of this patient's age, which adverse effects would take priority when planning care? A. Dry mouth and photosensitivity B. Anxiety, headaches, insomnia C. Drowsiness and sedation D. Urinary frequency
C. TCAs such as imipramine (Tofranil) may cause drowsiness and sedation. Because of this patient's age, these effects may increase the risk of falls. Options A, B, and D are incorrect. Headache, insomnia, and anxiety are not common adverse effects associated with imipramine. The drug may cause photosensitivity, dry mouth, and urinary retention, but these would not be the top priority considering the fall risk. The drug does not cause urinary frequency.
Levodopa is prescribed for a patient with Parkinson's disease. At discharge, which of the following teaching points should the nurse include? A. Monitor blood pressure every 2 hours for the first 2 weeks. B. Report the development of diarrhea. C. Take the pill on an empty stomach or 2 hours after a meal containing protein. D. If tremors seem to worsen, take a double dose for two doses and call the provider.
C. Taking dopamine replacement drugs such as levodopa with meals containing protein significantly impairs absorption. The drug should be taken on an empty stomach or 2 or more hours after a meal containing protein. Options A, B, and D are incorrect. Although the patient should be taught to rise gradually from lying or sitting to standing, the patient does not need to monitor blood pressure every 2 hours. Diarrhea should be reported but is unrelated to the effects of levodopa, and other causes should be explored. An increase in tremors should be evaluated, and the dose of the drug should not be independently increased.
A 32-year-old female patient has been taking lorazepam (Ativan) for her anxiety and is brought into the emergency department after taking 30 days' worth at one time. What antagonist for benzodiazepines may be used in this case? A. Epinephrine B. Atropine C. Flumazenil D. Naloxone
C. The competitive antagonist drug used in cases of benzodiazepine overdosage is flumazenil (Romazicon). Options A, B, and D are incorrect. Epinephrine, an adrenergic agonist, is not an antagonist to the benzodiazepines. Atropine is an anticholinergic, and naloxone is a competitive antagonist to opioid (narcotic) drugs.
The patient receives imipramine (Tofranil) as treatment for depression. He is admitted to the emergency department following an intentional overdose of this medication. What will the priority assessment by the nurse include? Select one: A. The patient's liver function B. The patient's renal status C. The patient's cardiac status D. The patient's neurological function
C. The patient's cardiac status
The physician has prescribed cromolyn (Intal) for the client with asthma. The nurse plans to do medication education. What will the best plan by the nurse include? Select one: A. This medication can affect blood glucose levels. B. This medication is indicated for acute asthma attacks. C. This medication will help prevent asthma attacks. D. This medication can result in hypertension.
C. This medication will help prevent asthma attacks.
A patient is receiving a thrombolytic drug, alteplase (Activase), following an acute myocardial infarction. Which of the following effects is most likely attributed to this drug? A: Skin rash with urticaria B: Wheezing with labored respirations C: Bruising and epistaxis D: Temperature elevation of 38.2°C (100.8°F)
C. Thrombolytic agents such as alteplase (Activase) dissolve existing clots rapidly and continue to have effects for 2 to 4 days. All forms of bleeding must be monitored and reported immediately. Options A, B, and D are incorrect. Skin rash, urticaria, labored respirations with wheezing, or temperature elevation are not directly associated with alteplase, and other causes should be investigated.
A patient with asthma has a prescription for two inhalers, albuterol (Proventil) and beclomethasone (Qvar). How should the nurse instruct this patient on the proper use of the inhalers? A. Use the albuterol inhaler, and use the beclomethasone only if symptoms are not relieved. B. Use the beclomethasone inhaler, and use the albuterol only if symptoms are not relieved. C. Use the albuterol inhaler, wait 5-10 minutes, then use the beclomethasone inhaler. D. Use the beclomethasone inhaler, wait 5-10 minutes, then use the albuterol inhaler.
C. Using a bronchodilating inhaler such as albuterol (Proventil, VoSpire) first, then waiting 5-10 minutes before using an ICS inhaler such as beclomethasone (Qvar), will allow the corticosteroid to reach deeper into the lungs following bronchodilation. Options A, B, and D are incorrect. The two inhalers have been prescribed together to maximize therapeutic effects. Using the beclomethasone before the albuterol may not allow the drug to reach deeply into the lungs for best effects.
The most productive way of managing stress would be to Select one: A. use anxiolytics. B. use a combined approach (drug use and non-pharmacological strategies). C. determine the cause and address it accordingly. D. practice meditation.
C. determine the cause and address it accordingly.
c. "This medication will prevent the inflammation that causes your asthma attack."
Client teaching regarding the use of antileukotriene agents such as zafirlukast (Accolate) should include which statement? a. "Take the medication as soon as you begin wheezing." b. "It will take about 3 weeks before you notice a therapeutic effect." c. "This medication will prevent the inflammation that causes your asthma attack." d. "Increase fiber and fluid in your diet to prevent the side effect of constipation."
A patient has an increased reaction to a drug following a change in her dietary habits. Which of the following changes would most likely be the cause? 1. Increased intake of grapefruit juice 2. Reduced intake of alcohol 3. Increased fiber intake 4. Reduced intake of citrus fruit
Correct Answer: 1 Grapefruit juice lowers the acidity of enzymes in the GI system that break down medications. This in turn results in higher medication absorption into the bloodstream. A reduction in citrus fruit intake would likely cause a lowered drug reaction. A reduced intake of alcohol or fiber would not likely produce an increased reaction to a drug. (p. 24)
An order for a medication to be given prn means 1. as needed. 2. every day. 3. at bedtime. 4. with food.
Correct Answer: 1 These are the letters used to designate as needed.
The pharmaceutical representative comes to the physician's office and says his company's pharmaceutical laboratory is marketing a drug that does not need approval by the Food and Drug Administration (FDA). What is the best response by the nurse? 1. "Any pharmaceutical laboratory in America must have approval from the Food and Drug Administration (FDA) before marketing a drug." 2. "Is this an over-the-counter (OTC) drug? They do not need approval by the Food and Drug Administration (FDA)." 3. "Is your pharmaceutical laboratory private? Only public pharmaceutical laboratories need approval from the Food and Drug Administration (FDA)." 4. "Your pharmaceutical laboratory must be involved in academic research because they are exempt from approval by the Food and Drug Administration (FDA)."
Correct Answer: 1 Any pharmaceutical laboratory, whether private, public, or academic, must obtain approval from the Food and Drug Administration (FDA) before marketing a drug. Private pharmaceutical laboratories must obtain approval from the Food and Drug Administration (FDA) before marketing a drug. Pharmaceutical laboratories involved in academic research must obtain approval from the Food and Drug Administration (FDA) before marketing a drug. Pharmaceutical laboratories that manufacture over-the-counter (OTC) drugs must obtain approval from the Food and Drug Administration (FDA) before marketing these drugs.
The client says to the nurse, "My wife and I take the same drug, but we have different side effects. Are we doing something wrong?" What is the best response by the nurse? 1. "No. Differences such as your sex can result in different side effects." 2. "I'll have to check. What is the name of the drug you were using?" 3. "Possibly. This could happen if one uses generic or brand name drugs." 4. "I'm not sure. Maybe the drug is not the same; you should check it."
Correct Answer: 1 Drugs may elicit different responses depending on individual client factors such as age, sex, body mass, health status, and genetics. Asking he client to check a medication is fine, but this does not answer the client's question. There are differences between some generic and brand name drugs, but this is not the best answer. The nurse should not have to check the drug; basic knowledge should include knowing that the sex of clients can result in different side effects.
The physician has ordered ipratropium (Atrovent) for the client. What is a priority assessment question for the nurse to ask prior to administering this medication? 1. "Are you allergic to soy? 2. "Do you have diabetes mellitus?" 3. "Do you have seizures?" 4. "Do you have gout?
Correct Answer: 1 Rationale 1: Ipratropium (Atrovent) is contraindicated in patients with hypersensitivity to soy as soya lecithin is used as a propellant in the inhaler. Rationale 2: Anticholinergic drugs do not impact glucose levels, so having diabetes mellitus is not a concern. Rationale 3: Anticholinergic drugs do not affect seizure disorders; this is not a concern. Rationale 4: Anticholinergic drugs are not contraindicated in clients with gout.
A client receives theophylline (Theo-Dur) and calls the clinic to say he has had nausea and vomiting for 2 days. What is the best action by the nurse? 1. Tell the client to come to the clinic for an assessment. 2. Ask the client if he has eaten at any unclean restaurants. 3. Ask the client if he has been exposed to anyone with the flu. 4. Recommend that the client begin a clear liquid diet
Correct Answer: 1 Rationale 1: Nausea and vomiting are symptoms of theophylline toxicity; the client needs to come to the clinic for an assessment. Rationale 2: Food poisoning could be the cause of the client's symptoms, but he needs to be assessed for theophylline toxicity. Rationale 3: Flu could be the cause of the client's symptoms, but he needs to be assessed for theophylline toxicity. Rationale 4: A clear-liquid diet might help, but the client needs to be assessed for theophylline toxicity.
The client receives albuterol (Proventil) via inhaler. He asks the nurse why he can't just take a pill. What is the best response by the nurse? 1. "When you inhale the drug the blood supply in your lungs picks it up rapidly, resulting in quicker effects." 2. "Because pills cannot help your illness; you must have inhaled medications for relief of symptoms." 3. "Because pills would produce too many side effects; you will have very few side effects with inhaled medications." 4. "Because this medication cannot be absorbed from your GI tract; the acid in your stomach would destroy it."
Correct Answer: 1 Rationale 1: The respiratory system offers a rapid and efficient mechanism for delivering drugs. The enormous surface area of the bronchioles and alveoli, and the rich blood supply to these areas, results in an almost instantaneous onset of action for inhaled substances. Rationale 2: Albuterol (Proventil) can be given orally (PO) but has a faster onset of action if inhaled. Rationale 3: Inhaled medications also produce side effects. Rationale 4: Oral medications are effective with some symptoms of respiratory disorders, but inhaled medications work faster.
The client is receiving a brand name drug and wants to change to the generic form because it is cheaper. What is the best outcome for this client? 1. Client will state two ways a brand name drug differs from a generic name drug. 2. Client will take the brand name drug after speaking with the physician. 3. Client will ask the nurse why brand name drugs are better than generic drugs. 4. Client will state two ways to obtain the medication at a reduced cost.
Correct Answer: 1 The dosage of drugs may be the same with a brand name and generic drug, but the bioavailability may be affected by the inert ingredients and tablet compression. Knowing ways to obtain medication at a reduced cost is an appropriate outcome, but the client will not learn why a brand name drug may be preferable over a generic drug. Referring the client to the physician is inappropriate because the nurse can educate the client about the difference between generic and brand name drugs. The client asking the nurse a question is not an outcome.
The nurse suspects that the patient has not been taking his prescribed antihypertensive medication because the patient's blood pressure remains elevated. What is the best therapeutic question the nurse can ask that will assess noncompliance? 1. "Taking medication is difficult for many people. What are some of your concerns about the medication?" 2. "Your blood pressure is really high; do you realize the serious consequences of not taking your medication?" 3. "I really doubt that you are taking your medication. What would you think about talking to the doctor?" 4. "You are one of my favorite patients and I want you to be safe. Are you really taking your medication?"
Correct Answer: 1 The most therapeutic question informs the patient that compliance is difficult for many people, and does not directly challenge the patient about not taking the medication. Telling the patient that the nurse doubts he is taking the medication directly challenges him, and recommending that he see the physician is threatening. Telling the patient his blood pressure is high and there are serious consequences is using the "scare tactic," and is non-therapeutic; the patient most likely is aware of the consequences. Telling the patient that he is a favorite is manipulating.
The patient is receiving a sustained-release capsule for his cardiac condition. The patient tells the nurse there is no way he can swallow such a large pill. What is the best response by the nurse? 1. "Withhold the medication and contact the physician." 2. "Place the capsule on the back of the patient's tongue, and have him drink a full glass of water." 3. "Open the capsule and sprinkle the contents over applesauce." 4. "Encourage the patient to try and swallow the capsule because it is the best medication for his heart condition."
Correct Answer: 1 The only option is to contact the physician. Several sustained-release medications cannot be opened and sprinkled on food. Placing the capsule on the back of the patient's tongue and having him drink a full glass of water may cause the patient to aspirate the capsule and/or the water. Encouraging the patient to try to swallow the capsule is coercive, and may result in the patient choking on the medication.

Which statements regarding the preclinical research stage of drug development are true? Select all that apply. 1. Most drugs do not proceed past the preclinical stage because they are found to be too toxic or just ineffective. 2. At the end of the preclinical research stage, client variability is determined and potential drug-to-drug interactions are examined. 3. The preclinical stage of research involves extensive testing on animals in the laboratory to determine if the drug will cause harm to humans. 4. Preclinical research results are always inconclusive. 5. The Food and Drug Administration (FDA) is responsible for extensive testing for safety before the pharmaceutical company can begin the preclinical research stage of development.
Correct Answer: 1, 3, 4 1: Most drugs do not proceed past the preclinical research stage of development because they are found to be either too toxic or just ineffective. 2: Client variability and potential drug-to-drug interactions are examined in Phase 3 of the clinical investigation process after Food and Drug Administration (FDA) approval. 3: The preclinical stage involves extensive testing on human, microbial cells, and animals to determine drug action and to predict whether the drug will cause harm to humans. 4: Because lab tests cannot accurately predict human response to a drug, these results are always inconclusive. 5: This extensive testing is done by the pharmaceutical company in the preclinical research stage of drug development, not the FDA.

A client who is admitted to the intensive care unit for monitoring notices the arthritis medication does not look like the one used at home and asks the nurse why. What is the nurseís best response? Select all that apply. 1. "This is a different brand from the one you use at home, but it will give you the same pain relief." 2. "Your health care provider feels we can safely substitute this drug for the drug you use at home." 3. "This generic drug is the one we have on formulary in the pharmacy. It has the same ingredients as the one you use at home." 4. "This is what we have in the pharmacy. Go ahead and take it for now and let me know if it doesn't relieve the pain." 5. "The medications in the hospital often do not look like the ones you get from the pharmacy."
Correct Answer: 1,2,3 Most brand-name drugs can be safely substituted with generic drugs. The exceptions to this rule are critical care drugs and drugs with a narrow margin of safety.
A patient admitted to the hospital tells the nurse she is very nervous about getting all her medications while she is in the hospital because her health care provider has her on a very "strict" schedule. Which principles describe how medication dosing schedules are determined? Select all that apply. 1. The physical and biologic characteristics of a drug may determine dosing schedule. 2. Specific times may improve effectiveness and decrease risk of adverse effects. 3. Some drugs must be taken a certain time prior to an event or immediately after an event. 4. Dosing may be set for the convenience of patient and nurse. 5. Hospitals have routine dosing intervals so that all patients receive medications at the same time each day.
Correct Answer: 1,2,3,4 1: The properties of a medication will determine how often it must be given to keep the drug at a therapeutic level in the body. 2: Some medications are administered at certain times of day to improve effectiveness or decrease adverse effects. 3: Some medications are taken to prevent or to cause an effect. For example, insulin should be given 30 minutes prior to eating to promote glucose usage. 4: If the drug does not have a characteristic that relies on a certain event to take place, then the drug can be given at the convenience of patient and/or nurse. 5: While most hospitals do have specific times of day (agency protocol) when medications are administered, this is not a principle that determines any specific dosing schedule.
The nurse is preparing medications prior to administration. To promote patient safety, the nurse uses "rights" of drug administration. What do these "rights" include? Select all that apply. 1. The right medication 2. The right time of delivery 3. The right dose 4. The right route of administration 5. The right patient
Correct Answer: 1,2,3,4,5 The five rights of drug administration are the right patient, the right medication, the right dose, the right route of administration, and the right time of delivery.
The nurse has finished teaching a patient's husband how to administer drugs and enteral feeding through a gastrostomy tube. The nurse knows the husband understands the use of the tube when he makes which statement? Select all that apply. 1. "My wife has a gastrostomy tube instead of a nasogastric tube because she will have the tube for a long time." 2. "I will need to use liquid medications. If any of the medications are in pill form, I will use the pill crusher to crush them and mix them with water before putting them in the tube." 3. "This medication says it is enteric coated. I'm not supposed to crush this kind of medication. I will need to ask the doctor to substitute another medication that is liquid or can be crushed." 4. "There's a big difference in how the drugs work in the body when they're taken orally and when they're administered through the tube. That's why my wife has to have this tube." 5. "I have to be very careful to flush the tube after I put medication in it. If I don't, the tube could get clogged."
Correct Answer: 1,2,3,5 4: Drugs administered via gastrostomy tube are affected by the same physiological processes as those given orally.
The physician ordered an intravenous medication for a patient with nausea. The patient asks the nurse how it will help his nausea. What is the best response by the nurse? 1. "We have more intravenous drugs for nausea than we do oral drugs." 2. "If you take an oral medication, you will just vomit it up." 3. "This will work much faster for your nausea." 4. "You can't have anything by mouth, so will receive the medication intravenously."
Correct Answer: 3 The intravenous route provides the quickest route of medication absorption. Telling the patient that he will vomit the medication is non-therapeutic. Telling the patient that the nurse has more intravenous drugs than oral drugs does not answer the patient's question. There is no evidence that the patient cannot have anything by mouth.

A client diagnosed with COPD says, "I don't see why I need to stop smoking. The damage to my lungs is already done." How should the nurse respond to this statement? Select all that apply. 1. "If you stop smoking now, your COPD may not get worse as fast." 2. "If you stop smoking, your lungs will get better pretty quickly." 3. "Your symptoms might not be as bad if you aren't smoking." 4. "You are probably correct, but you should at least try." 5. "If I were you, I would enjoy what time I have left."
Correct Answer: 1,3 Rationale 1: Smoking cessation has been shown to slow the progression of COPD. Rationale 2: Depending on the extent of damage, the client's lungs may not get better at all, but may just stop getting worse. Rationale 3: Smoking cessation has been shown to result in fewer respiratory symptoms. Rationale 4: It is not therapeutic to tell the client that he is correct with this statement. Rationale 5: The nurse should encourage the client to stop smoking.
The nurse is caring for a patient who has been involved in a motor vehicle crash. The health care provider has written orders for a transdermal patch for pain to be applied for steady pain control. The nurse knows that Select all that apply. 1. the transdermal patch should not be applied to areas of abrasion. 2. transdermal medications undergo the first-pass effect in the liver. 3. transdermal medications completely bypass digestive enzymes. 4. the actual dose received by the patient from this pain patch may vary. 5. transdermal patches are not considered an effective means of delivering medications because the rate of delivery and actual dose can vary.
Correct Answer: 1,3,4 1: Applying transdermal patches to skin that has abrasions may unintentionally increase the dose of the medication. 2: Transdermal medications avoid the first-pass effect. 3: Transdermal medications never come into contact with digestive enzymes but go straight into the bloodstream. 4: While transdermal patches do contain a specific amount of medication, the rate of delivery may vary for each patient. 5: It is true that the rate of delivery and actual dose received can vary, but this route is an effective means of delivering many medications such as birth control medications and nitroglycerin for angina.
The client receives beclomethasone (Beconase). What will the best assessment by the nurse include? Select all that apply. 1. Assess the client's mouth for any sign of fungal infection. 2. Assess the client's blood glucose prior to administration of nasal spray. 3. Assess if the client has blown his nose prior to administration of nasal spray. 4. Assess if the client has had a change in taste. 5. Assess the client for any hoarseness or change in voice
Correct Answer: 1,3,4,5 Rationale 1: Clients may develop candidiasis so the mouth should be assessed. Rationale 2: There is no need to assess the client's blood glucose. Rationale 3: The client should gently blow the nose prior to use to clear the nasal passages. Rationale 4: Clients may experience a change in taste. Rationale 5: Clients may experience a change in voice as a local effect.
A nurse is explaining the process of respiration to a client. Which information should be given? Select all that apply. 1. "Moving air in and out of the lungs is really called ventilation." 2. The smooth muscle in the alveoli helps to pull air into the lungs. 3. Exchange of oxygen and carbon dioxide occurs across a thin capillary membrane. 4. Respiration is not effective without perfusion. 5. Your basic respiratory drive is determined by your brain.
Correct Answer: 1,3,4,5 Rationale 1: Ventilation is the process of moving air into and out of the lungs. Rationale 2: There is no smooth muscle in the alveoli. Rationale 3: The blood stays in capillaries. A thin membrane separates airway from capillary. Rationale 4: Perfusion is the blood flow through the lungs. Without this blood flow, the oxygen-carbon dioxide exchange does not take place. Rationale 5: The rate is determined by neurons in the brainstem and can be affected by a number of factors.
The nurse uses the nursing process prior to administering any medications. Which step will assure the best patient safety? 1. Assess the patient's developmental level. 2. Assess the patient's medical history. 3. Assess the patient's disease process. 4. Assess the patient's learning needs.
Correct Answer: 2 An assessment of the patient's medical history, which includes allergies, is the most important assessment prior to administering medications. Assessing the patient's learning needs is important for medication education, but not for safely administering medications. Assessing the patient's developmental level is important for medication education, but not for safely administering medications. Assessing the patient's disease process is important in evaluating the effects of the medications, but not for safely administering medications.
Which patients should the nurse be concerned about regarding nonadherence to prescribed medication regimens? Select all that apply. 1. A 70-year-old hypertensive male patient who has a prescription for a diuretic and is complaining that his medication is keeping him up all night 2. A 30-year-old college student who has a prescription for birth control pills and tells the nurse she has had breakthrough bleeding this past cycle 3. A 45-year-old diabetic who has a prescription for insulin and whose blood sugar is within the normal range 4. A 57-year-old day laborer who has a prescription for Lipitor for high cholesterol and a prescription card for a free health clinic 5. An 18-year-old male with a prescription for an acne medication that must be taken 4 times a day
Correct Answer: 1,5 1.This patient has been taking his diuretic in the evening instead of in the morning and is most likely experiencing increased urination at night that is disrupting his sleep. Adverse side effects are common causes for nonadherence. 2.Birth control pills often cause midcycle bleeding. This does not raise any red flags for nonadherence. 3.One of the most common reasons for nonadherence is forgetting a dose, particularly with drugs that must be taken more than twice a day.
The client has skin lesions that have not responded to prescription drugs. He tells the nurse he has heard about some research going on with a new drug and questions why he can't take it. What is the best response by the nurse? 1. "I know it is frustrating, but the Food and Drug Administration (FDA) approval process is in place to ensure that drugs are safe." 2. "The Food and Drug Administration (FDA) has very strict rules about new drugs; it is important to be patient regarding the review/approval process." 3. "Your skin lesions really aren't that bad, but maybe the new drug will be available soon." 4. "Maybe you could contact the drug company about becoming involved in a clinical trial."
Correct Answer: 1. Although the public is anxious to receive new drugs, the fundamental priority of the Food and Drug Administration (FDA) is to ensure that drugs are safe. Also, telling the client that the nurse knows he is frustrated is therapeutic because it communicates that the nurse recognizes what he is feeling. The client could contact the drug company, but this response fosters false hope as he may not be a viable candidate for this drug. Telling the client his skin lesions "aren't that bad" is a non-therapeutic response; the client's perception is his reality. Telling the client to be patient is a condescending response; the client wants relief from the skin condition.
What percentage of Americans takes at least one prescription drug per year? 1. 50% 2. 10% 3. 40% 4. 25%
Correct Answer: 1. 50%
The student nurse has completed an initial pharmacology course and tells the nursing instructor that it was difficult and she is glad it is over. What is the best response by the nursing instructor? 1. "It may be over, but now you must apply what you have learned to patient care." 2. "Learning is gradual and continuous; we never completely master all areas of pharmacology." 3. "Learning is always painful, but we must continue anyway." 4. "It really isn't over; you should take a graduate course next."
Correct Answer: 2 Learning pharmacology is a gradual, continuous process that does not end with graduation. Never does one completely master every facet of drug action and application. There is no reason for the student nurse to take a graduate level pharmacology course at this time. It is true that the student must apply what has been learned to patient care, but this response implies that learning is over. Learning is not always painful.
The physician prescribes an oral medication for the patient. What is the primary nursing assessment of the patient prior to receiving this medication? 1. The patient's understanding of the medication 2. The patient's ability to swallow 3. The patient's allergies 4. The patient's eyesight
Correct Answer: 2 The ability of the patient to swallow is a safety issue to prevent aspiration of the medication. The patient's understanding is important, but not a priority. The patient's eyesight is not significant. The patient's allergies are important, but if the patient cannot swallow the medication, then the allergies are not significant.
The nurse plans to administer heparin by drawing the heparin up in an appropriate syringe, donning gloves, prepping the patient's abdominal area, injecting the needle, aspirating for blood, and injecting the medication. Which statement best describes the nurse's plan? 1. The nurse does not need to wear gloves. 2. The nurse should not aspirate for blood. 3. The nurse does not need to prep the skin. 4. The nurse performed the injection correctly.
Correct Answer: 2 When performing heparin injections, the nurse should not aspirate for blood as this may cause bruising or bleeding. Gloves must always be worn for invasive techniques. The nurse did not perform the correct technique. The skin should be prepped with alcohol prior to administering an injection.
The nurse is providing medication education to a client with hypertension. The nurse teaches the client that the physician ordered a diuretic to decrease the amount of fluid in his body. Which statement best describes the nurse's instruction? 1. The nurse provided appropriate medication education. 2. The nurse explained the drug's mechanism of action. 3. The nurse taught the client about a prototype drug. 4. The nurse explained the consequences of not using the drug.
Correct Answer: 2 A drug's mechanism of action explains how a drug produces its effect in the body. The nurse did not explain the consequences of not using the drug. The nurse is not teaching the client about a prototype drug. The education was most likely appropriate, but this response is too vague.
The client is receiving a very expensive medication. The client asks the nurse why the medicine is so expensive. What is the best response by the nurse? 1. "It is expensive, but your insurance covers it and you have a low co-pay." 2. "Drug companies are allowed to advertise medications and this adds to the cost." 3. "Drug companies must recoup the cost of developing and producing the drug." 4. "I think the drug companies should be more accountable for lowering costs."
Correct Answer: 2 Advertising by drug companies costs several billion dollars a year and this adds to the cost of the drug. Telling the client that drug companies must be allowed to recoup the cost implies that the nurse is defending the drug companies. Telling the client that his insurance covers the drug doesn't answer his question. It is non-therapeutic for the nurse to introduce her own beliefs, such as accountability of drug companies, into a conversation with the client.
The client says to the nurse, "My doctor said my drug is a controlled substance; am I considered an addict?" What is the best response by the nurse? 1. "Are you concerned about becoming an addict? We can discuss this in more detail it you would like to." 2. "You are not an addict; the Drug Enforcement Administration (DEA) restricts the use of drugs with a high potential for abuse." 3. "Why do you ask about becoming an addict? Not many of our clients have asked this question." 4. "You are not an addict, but the Drug Enforcement Administration (DEA) will monitor you for this."
Correct Answer: 2 Drugs that have a high potential for addiction are considered controlled substances. The Drug Enforcement Administration (DEA) does not monitor clients for addiction when they receive controlled substances. It is premature at this time to ask the client if he is concerned about addiction; there is no information to support an addiction. "Why" questions are considered non-therapeutic because they put the client on the defensive.
While in the hospital, the pediatric patient has been receiving amoxicillin 10 mL orally bid, pc. The child will be going home on this medication. What is the best instruction by the nurse for the parents? 1. Give 2 teaspoons by mouth, 3 times a day, on an empty stomach. 2. Give 2 teaspoons by mouth, twice a day, after meals. 3. Give 2 teaspoons by mouth, 3 times a day, after meals. 4. Give 2 teaspoons by mouth, twice a day, with meals.
Correct Answer: 2 Giving 2 teaspoons by mouth, twice a day, after meals is correct.
The nurse is preparing to administer beclomethasone (Beconase) to several clients. For which client would the nurse hold the drug and contact the physician? 1. The client who has had a myocardial infarction (MI) 2. The client who has methicillin resistant Staphylococcus aureus (MRSA) 3. The client who has diabetes mellitus 4. The client who has terminal cancer
Correct Answer: 2 Rationale 1: Beclomethasone (Beconase) is not contraindicated in clients who have had a myocardial infarction. Rationale 2: Glucocorticoids can mask the signs of infection and are contraindicated if active infection is present. Rationale 3: Beclomethasone (Beconase) is not contraindicated in clients who have diabetes mellitus. Rationale 4: Beclomethasone (Beconase) is not contraindicated in clients who have terminal cancer.
The client asks the nurse why she must continue taking her asthma medication even though she has not had an asthma attack in several months. What is the best response by the nurse? 1. "The medication needs to be taken indefinitely according to your doctor, so you should discuss this with him." 2. "The medication is still needed to decrease inflammation in your airways and help prevent an attack." 3. "The medication needs to be taken or your lungs will be severely damaged, and we will not be able to stop an acute attack." 4. "The medication needs to be taken for at least a year; then, if you have not had an acute attack, you can stop it.
Correct Answer: 2 Rationale 1: The nurse is able to answer the client's question; it does not need to be referred to the physician. Rationale 2: Effective treatment of asthma includes long-term treatment to prevent attacks and decrease inflammation, as well as short-term treatment when an attack occurs. Rationale 3: Telling a client that his or her lungs will be severely damaged is non-therapeutic; the inability to prevent an acute attack in this client is not true. Rationale 4: Long-term treatment of asthma continues indefinitely, not for just 1 year.
The client is receiving methadone (Dolophine), a Schedule II drug. The client says to the nurse, "A pharmacist told me his pharmacy must register with the Drug Enforcement Administration (DEA) to give me this drug; will DEA agents be snooping around my house?" What is the best response by the nurse? 1. "It is probably unlikely that Drug Enforcement Administration (DEA) agents will be bothering you." 2. "No, the Drug Enforcement Administration (DEA) restricts drugs that have a high potential for abuse." 3. "No. I think our system should be more like Europe; they have fewer controlled drugs." 4. "That's an interesting question. Are you worried about the Drug Enforcement Administration (DEA)?"
Correct Answer: 2 The Controlled Substance Act of 1970 restricts the use of drugs that have a high potential for abuse. Hospitals and pharmacies must register with the Drug Enforcement Administration (DEA) to obtain a specific registration number that will enable them to purchase controlled drugs. Telling the client that Drug Enforcement Administration (DEA) agents will "probably" not bother him can lead the client to think DEA agents might bother him. Asking the client if he is worried about the Drug Enforcement Administration (DEA) puts him on the defensive and is non-therapeutic. By saying that our system should be more like Europe's, the nurse is introducing her beliefs and this is non-therapeutic; the client may not agree.
The nursing instructor teaches the student nurses about the pharmacological classification of drugs. The instructor evaluates that learning has occurred when the students make which response? 1. "An anti-anginal treats angina." 2. "A calcium channel blocker blocks heart calcium channels." 3. "An antihypertensive lowers blood pressure." 4. "An anticoagulant influences blood clotting."
Correct Answer: 2 The pharmacological classification addresses a drug's mechanism of action, or how a drug produces its effect in the body. To say that a drug influences blood clotting addresses the therapeutic usefulness of the drug, not the pharmacological classification. To say that a drug treats angina addresses the therapeutic usefulness of the drug, not the pharmacological classification. To say that a drug lowers blood pressure addresses the therapeutic usefulness of the drug, not the pharmacological classification.
Which of the following is accurate regarding medication administration via the intradermal route? 1. Injections should be limited to 1-2 milliliters. 2. Hairy sites should be avoided. 3. Usual administration sites include the upper and lower abdomen. 4. Medications should be injected into the epidermis skin layer.
Correct Answer: 2 Usual sites of intradermal administration include nonhairy surfaces, including the forearm, upper chest, and scapulae. Intradermal injection involves administering small amounts (0.1-0.2 milliliters) of medication into the dermis layer of skin. (p. 32)
A patient who takes albuterol (Proventil) reports to the emergency department with reports of fatigue and palpitations. The nurse would closely assess which laboratory test? 1. Amylase 2. Electrolytes 3. Hemoglobin 4. Arterial blood gases
Correct Answer: 2 Rationale 1: Albuterol does not affect amylase. Rationale 2: Albuterol can cause hypokalemia. Potassium is an electrolyte. Rationale 3: Albuterol does not cause bleeding. Rationale 4: The patient may have ABGs drawn to check asthma status, but this test is not indicated by fatigue and palpitations.
The nurse is teaching a pharmacology class to student nurses. What does the nurse include as key events in the history of pharmacology? Select all that apply. 1. Initial drugs included morphine, cocaine, and penicillin. 2. Early researchers used themselves as test subjects. 3. The initial intention of pharmacology was to relieve human suffering. 4. Modern pharmacology began in the early 1600s. 5. Pharmacologists synthesized drugs in the laboratory in the twentieth century.
Correct Answer: 2, 3, 5 The early roots of pharmacology included the application of products to relieve human suffering, and early researchers used themselves as test subjects. Initial drugs included morphine, colchicines, curare, and cocaine, but not penicillin. Modern pharmacology began in the early 1800s, not the 1600s. By the twentieth century, pharmacologists could synthesize drugs in the laboratory.
A prototype drug is a single drug in a class and can be compared with all other medications in the class. The benefit of studying the prototype drug is that the nurse would be able to predict characteristics of other drugs in the same class, including Select all that apply. 1. which drugs have the most favorable safety profile. 2. their therapeutic indications. 3. their actions and adverse effects. 4. their specific clinical use. 5. contraindications specific to any drug in that group.
Correct Answer: 2,3,4 Studying the therapeutic indications of a prototype drug may allow the nurse to predict actions and adverse effects of other drugs in the same group & same class. Contraindications may differ for specific drugs in the same class as the prototype.
A patient has been referred to an allergist for allergy testing. Which parenteral routes would the nurse not expect to be used for the tests? Select all that apply. 1. The intradermal (ID) route 2. The subcutaneous route 3. The intramuscular (IM) route 4. The intravenous (IV) route 5. The buccal route
Correct Answer: 2,3,4,5 1: The ID route is used to administer very small volumes of a drug into the intradermal layer of skin. This route is most commonly used for allergy and TB skin testing. 2: The subcutaneous route is used to deliver medication into the deepest layer of skin. Drugs that are delivered by this route include insulin, heparin, and some vaccines. 3: The IM route is used to deliver medication deep into a muscle. Antibiotics, vitamins, and some vaccines are delivered by this route. 4: The IV route delivers medication directly into the bloodstream. Fluid replacement, antibiotics, blood products, and many other drugs can be delivered via this route. 5: Medications administered by the buccal route are intended to be absorbed. This is not a route used for allergy testing.
The physician has ordered several medications for the patient. What does the nurse recognize as responsibilities regarding administration of medications? Select all that apply. 1. Knowing whether or not the medication is on the hospital formulary 2. Knowing the reason the medication was prescribed for this patient 3. Knowing how the medication is to be administered. 4. Knowing how the medication is supplied by the pharmacy 5. Knowing the name of the medication
Correct Answer: 2,3,4,5 How the medication is supplied by the pharmacy, how the medication is to be administered, the name of the medication, and the reason the medication was prescribed for the patient are the responsibilities of the nurse regarding medication administration. Whether or not a drug is on a hospital formulary list is not a primary responsibility of the nurse.
A patient at a community health center has been prescribed oral medications and tells the nurse that medications were administered intravenously when the patient was in the hospital. The nurse discusses the benefits and disadvantages of oral medications, including which facts? Select all that apply. 1. The oral route is considered the second safest route, after the intradermal route. 2. Tablets that are scored may be crushed for easier swallowing. 3. Enteric-coated drugs are designed to dissolve in the stomach, not the small intestine. 4. A major disadvantage of oral medications is that the patient must be conscious and able to swallow. 5. Enteric-coated drugs should be crushed to help facilitate dissolving by the stomach acid.
Correct Answer: 2,4 1: The oral route is considered the safest because the skin barrier is not compromised; if an overdose occurs, drugs remaining in the stomach can be evacuated with stomach contents. 2: The purpose of scoring a tablet is the greater ease of cutting the tablet in half or quarters. These same tablets may be crushed, if needed. 3: Some drugs irritate the stomach lining and are coated to prevent being dissolved in the stomach. These drugs go on to the small intestine and are dissolved in the alkaline environment. 4: This is a major disadvantage of oral medications. 5: Enteric-coated drugs are designed specifically to bypass the stomach's acidic environment and continue to the alkaline environment of the small intestine.
Modern pharmacology was introduced to the United States by the opening of the first department of pharmacology at the University of Michigan in the year 1. 1805. 2. 1890. 3. 1847. 4. 1908.
Correct Answer: 2.
The application of drugs for the purpose of disease prevention and treatment of suffering is known as 1. biologics. 2. pharmacotherapeutics. 3. alternative therapies. 4. therapeutics.
Correct Answer: 2. Pharmacotherapeutics is the application of drugs for the purpose of disease prevention and the treatment of suffering.
A drug manufacturer that is performing the effects of a drug on laboratory animals would be in which phase of the new drug development timeline? 1. Clinical Investigation 2. Preclinical Investigation 3. New Drug Application Review 4. Postmarketing Studies
Correct Answer: 2. Preclinical investigation involves laboratory research on nonhuman subjects.
The nurse administers a vaccine to a child. What is the best understanding of the nurse as it relates to the manufacture of this vaccine? 1. The vaccine is produced by natural plant extracts in the laboratory. 2. The vaccine is naturally produced in animal cells or microorganisms. 3. The vaccine is produced by a combination of animal and plant products. 4. The vaccine is most commonly synthesized in a laboratory.
Correct Answer: 2. Vaccines are naturally produced in animal cells, microorganisms, or by the body itself. Vaccines are not synthesized in a laboratory. Vaccines are not produced by natural plant extracts. Vaccines are not produced by a combination of animal and plant products.
Advil, Motrin, and Nuprin are examples of 1. chemical names. 2. combination names. 3. trade names. 4. generic names.
Correct Answer: 3 Advil, Motrin, and Nuprin are trade names for ibuprofen. (p. 6)
The patient is having chest pain. The physician orders sublingual nitroglycerine STAT. The nurse obtains the medication from the pharmacy and administers it to the patient 30 minutes later. Which statement best describes the nurse's action? 1. The medication should have been administered immediately. 2. The physician should have specified the time frame for the medication. 3. The medication should have been administered within a 5-minute time frame. 4. The nursing action was correct because the medication was not on the unit.
Correct Answer: 3 For a STAT order, the time frame between writing the order and administering the drug should be 5 minutes or less. Not having a drug on the unit is not an excuse, as commonly ordered STAT medications should be kept in stock. Although the drug does not need to be administered immediately, it should be done within 5 minutes. It is not the physician's responsibility to specify the time frame.
The physician has prescribed a brand name drug for the client. The client tells the nurse that the medication is too expensive. What is the best plan by the nurse? 1. Help the client receive free medicine through a "patient assistance" program. 2. Ask the physician if a cheaper brand name drug may be substituted. 3. Ask the physician if a generic drug may be substituted. 4. Maintain the client on samples of the brand name drug from the physician's office.
Correct Answer: 3 Generic drugs are much less costly than brand name drugs. A patient assistance program is a good idea, but since the client may not qualify for this it is not the best plan. Another brand name drug may not be what the client needs for the illness. Providing samples is an option, but the office may temporarily run out of samples and the client will not receive the medication.
Which drug has the highest dependency potential? 1. Acetaminophen 2. Codeine 3. Heroin 4. Diazepam
Correct Answer: 3 Heroin is a Schedule I drug, and has the highest potential for abuse, physical dependence, and psychological dependence of the drugs listed. (p. 17)
The student nurse is taking a pharmacology course and studying about the Food and Drug Administration (FDA). What has the student learned about how the FDA has decreased the amount of time involved in bringing a new drug to the market? 1. The Food and Drug Administration (FDA) is not as strict as it once was with regard to drug approval. 2. Since consumers have demanded more drugs, the Food and Drug Administration (FDA) has streamlined the review/approval process. 3. Drug manufacturers are required to pay yearly user fees, which allow the Food and Drug Administration (FDA) to hire more employees to increase its efficiency. 4. Drug manufacturers are required by the Food and Drug Administration (FDA) to test more drugs on an annual basis.
Correct Answer: 3 In 1992, the Prescription Drug User Fee Act was passed. This required drug manufacturers to provide yearly product user fees so the Food and Drug Administration (FDA) could restructure, hire more employees, and operate more efficiently. The Food and Drug Administration (FDA) is just as strict now as it always was with regard to drug approval. The Food and Drug Administration (FDA) has not streamlined the review/approval process. The Food and Drug Administration (FDA) does not require drug manufacturers to test more drugs on an annual basis.
The nurse administers an oral preparation of liquid Tylenol 650 mg as ordered. Afterward, the patient indicates he had been receiving Tylenol 650 mg in pill form. Which of the following is accurate in regards to the five rights? 1. The nurse failed to deliver the correct dose. 2. The nurse failed to administer the right medication. 3. The nurse did not violate the five rights. 4. The nurse failed to give the medication via the correct route.
Correct Answer: 3 Nothing in the question depicts a violation of the five rights.
The patient is 3 days postop, and the physician orders an oral pain medication. The patient asks the nurse if it wouldn't be better to get the medication in the intravenous (IV) line. What is the best response by the nurse? 1. "No, because you could not medicate yourself intravenously (IV) at home." 2. "No, because pills are more effective than intravenous (IV) medications." 3. "No, because pills are safer than intravenous (IV) medications." 4. "No, because we are going to take your intravenous (IV) line out."
Correct Answer: 3 Oral medications are safer than intravenous (IV) medications. Telling the patient that she cannot have the medication intravenously because the intravenous line is to be removed does not answer the patient's question. There is no evidence that the patient will be going home with an intravenous line, so this answer is incorrect. Oral medications are not more effective than IV medications.
The physician has prescribed cromolyn (Intal) for the client with asthma. The nurse plans to do medication education. What will the best plan by the nurse include? 1. This medication is indicated for acute asthma attacks. 2. This medication can affect blood glucose levels. 3. This medication will help prevent asthma attacks. 4. This medication can result in hypertension.
Correct Answer: 3 Rationale 1: Cromolyn (Intal) is ineffective for acute asthma attacks. Rationale 2: Cromolyn (Intal) does not affect blood glucose levels. Rationale 3: By reducing inflammation, cromolyn (Intal) is able to prevent asthma attacks. Rationale 4: Cromolyn (Intal) does not cause hypertension.
The client receives ipratropium (Atrovent). She tells the nurse she is going to stop it because of the bitter taste in her mouth after using the medication. What is the best response by the nurse? 1. "That is a good idea; you are experiencing a serious side effect." 2. "That is a common side effect; it will go away in time." 3. "You can decrease that side effect by rinsing your mouth after use." 4. "Are you sure you are using the medication properly?
Correct Answer: 3 Rationale 1: The client is not experiencing a serious side effect; there is no need to stop the medication. Rationale 2: The bitter taste will not go away in time; the client must rinse her mouth. Rationale 3: Ipratropium (Atrovent) produces a bitter taste, which may be relieved by rinsing the mouth after use. Rationale 4: Asking how the client uses the medication may be a good option but not with the common side effect of bitter taste
The physician ordered a brand name drug for the client, paroxetine (Paxil). After taking this medication for a year, the client tells the nurse that it is no longer working. What is the best assessment of the nurse at this time? 1. "This sounds like your medication needs changing." 2. "Let's look for interactions with other medications you are taking." 3. "Are you taking Paxil or paroxetine?" 4. "It is time for us to do the Beck Depression assessment again."
Correct Answer: 3 The bioavailability of a generic drug may not be the same as the bioavailability of a brand name drug. Assessing for worsening of depression is appropriate, but the nurse should first assess if the patient has changed to a generic form of the drug.
The physician orders enteric-coated aspirin, 300 mg every day, for the patient with a nasogastric tube. What is the priority action by the nurse? 1. Crush the tablet, dissolve it in 30 mL of water, and administer through the tube. 2. Put the tablet in the tube, "milk" it down the tube, and then flush the tube with 60 mL of water. 3. Withhold the medication and contact the physician. 4. Substitute plain aspirin, dissolve it in 30 mL of water, and administer through the tube.
Correct Answer: 3 The only option is to withhold the medication and contact the physician. Crushing the tablet destroys the enteric coating. Putting the tablet in the tube will result in clogging of the tube. The nurse cannot substitute plain aspirin; this requires a physician's order.
The physician ordered an oral medication. The nurse incorrectly administered the medication intravenously. What does the best analysis of the nurse's action reveal? 1. An antidote cannot be given. 2. The nurse will be terminated from her job. 3. The medication cannot be retrieved. 4. A lawsuit by the patient will be impending.
Correct Answer: 3 When a medication is given intravenously, its effects cannot be reversed because it is already in the bloodstream. A lawsuit may occur, but this is not the primary concern; patient safety is the primary concern. The nurse may be terminated, but patient safety is the main concern, and the effect of the medication cannot be reversed. Antidotes may be given, but this must be done very quickly.
Which condition is an adverse effect of a beta-adrenergic agonist? 1. Bradycardia 2. Constipation 3. Tachycardia 4. Runny nose
Correct Answer: 3 Rationale 1: Beta-adrenergic agonists cause tachycardia, not bradycardia. Rationale 2: Diarrhea can occur with some leukotrienes. Rationale 3: Tachycardia is common, along with restlessness. Rationale 4: Dry mucous membranes can occur
Which statement is true regarding dry powder inhalers (DPI)? 1. The medication is delivered by tablet orally. 2. The medication is delivered by fine mist. 3. The device is activated by inhalation. 4. The medication is applied topically.
Correct Answer: 3 Rationale 1: Inhalers are not oral tablets. Rationale 2: Nebulizers deliver medications in fine mist. Rationale 3: The client activates the device by inhaling. Rationale 4: Inhalers are not applied topically.
The nurse is teaching a medication class for parents of children with attention-deficit hyperactivity disorder who are receiving stimulant medications. The nurse has reviewed reasons why the medications are restricted. The nurse determines that learning has occurred when the parents make which response(s)? Select all that apply. 1. "The use of these medications is restricted so that the pharmacies can track the rate of drug abuse in our city." 2. "The use of these medications is restricted because the physician needs to evaluate our child more often." 3. "The use of these medications is restricted because they have the potential for abuse." 4. "The use of these medications is restricted so that the drug companies can make a bigger profit." 5. "The use of these medications is restricted because this is the current law."
Correct Answer: 3, 5 The Controlled Substance Act is the law under which medications with abuse potential are restricted. Stimulant medications are considered controlled substances. More frequent evaluations are a good plan, but this is not the reason for restricted use of stimulant medications. Drug companies do not make a bigger profit when medications are listed as restricted. Pharmacies do not track the rate of drug abuse in cities.
The physician orders a brand name drug for the client. The hospital formulary substitutes the generic equivalent of the brand name drug, and the nurse administers the generic drug. Which statement(s) best represents the nurse's action? Select all that apply. 1. The nurse should have contacted the physician prior to administering the drug. 2. The nurse should have called the pharmacist to see if the drugs were bioequivalent. 3. The nurse used good judgment in administering the drug. 4. The nurse was correct; hospital policies allow for this.
Correct Answer: 3,4 The nurse used good judgment as hospital policies allow for generic substitution of certain drugs. If there is a concern, the pharmacist should contact the physician. It is not feasible for the nurse to contact the physician every time there is a generic substitution. Physicians are aware of the hospital formulary.
A client has been prescribed a leukotriene modifier. Which assessment finding would cause the nurse to question this prescription? Select all that apply. 1. The client is 54 years old. 2. The client reports frequent foot cramps. 3. The client reports drinking two or three mixed alcohol drinks each day. 4. The client has chronic hepatitis C. 5. The client has a history of a CVA 2 years ago.
Correct Answer: 3,4 Rationale 1: The concern would be for persons over age 65, who may experience increased frequency of infections. Rationale 2: There is no reason to avoid giving this medication to a client who has foot cramps. Rationale 3: Chronic alcohol users may not tolerate these medications as they are extensively metabolized by the liver. Rationale 4: Significant hepatic dysfunction is a contraindication to this medication as it is extensively metabolized by the liver. Rationale 5: There is no contraindication for the use of this medication in a client with history of CVA.
The client receives ipratropium (Atrovent) via inhalation for the treatment of chronic asthma. The nurse plans to do medication education with the client. What will the best plan by the nurse include? Select all that apply. 1. Wait 15 minutes before using any other inhaled medications. 2. The medication may also be used for acute asthma attacks. 3. Report any increased dyspnea. 4. Report any changes in urinary pattern. 5. Use the medication consistently, not occasionally.
Correct Answer: 3,4,5 Rationale 1: It is only necessary to wait 2-3 minutes, not 15 minutes, between inhaled medications. Rationale 2: Anticholinergic drugs will not terminate an acute asthma attack, as peak effects may take 1 to 2 hours. Rationale 3: The client should be advised to report any symptoms of deteriorating respiratory status such as increased dyspnea. Rationale 4: Anticholinergic drugs can result in urinary retention, and the client should report any changes in urinary patterns. Rationale 5: To get the most benefit from ipratropium (Atrovent), it must be used consistently.
An overwhelmed nursing student asks the instructor whether there are any tips that will make learning pharmacology easier. The instructor gives an example of the anticoagulant heparin. The instructor indicates that knowing heparin and comparing other drugs to it will facilitate learning the many anticoagulants. Which approach is the instructor using? 1. Mechanism of action approach 2. Generic name approach 3. Trade name approach 4. Prototype drug approach
Correct Answer: 4 Heparin is the generic name, but comparing one well-understood drug with others in the same class is known as the prototype approach. (p.6)
A client says, "My doctor told me that I have COPD and might develop emphysema. I always thought I had chronic bronchitis." How should the nurse respond to this statement? Select all that apply. 1. "Are you certain he didn't say you have asthma?" 2. "Chronic bronchitis doesn't have anything to do with COPD." 3. "COPD is either asthma, chronic bronchitis, or emphysema, or a combination of those disorders." 4. "As COPD progresses, it becomes emphysema." 5. "Both diagnoses are correct."
Correct Answer: 3,4,5 Rationale 1: There would be no reason to ask this question. It is logical that a client with chronic bronchitis would have a COPD diagnosis. Rationale 2: The three specific COPD conditions are asthma, chronic bronchitis, and emphysema. Rationale 3: The three specific COPD conditions are asthma, chronic bronchitis, and emphysema. Rationale 4: COPD is progressive, with the terminal stage being emphysema. Rationale 5: Chronic bronchitis is a form of COPD, so both diagnoses are plausible
A client who received a refill for a medication returns to the pharmacy and says, This medication is wrong! It doesnít look anything like my usual prescription.î Which response by the pharmacist would be most appropriate? Select all that apply. 1. "Your usual prescription drug is too expensive, so I substituted it with a generic one." 2. "There is no difference between this drug and the one you usually get." 3. "Our state allows me to substitute a generic drug when the prescription calls for a brand-name drug." 4. "Don't worry. Can you see that the generic ingredients are exactly the same?" 5. "This medication is a generic form of your other medication. That is why it looks different. But it has the same ingredients and should work the same way."
Correct Answer: 3,5 Some states allow the pharmacist to routinely substitute a generic drug for a brand-name drug. Other states prohibit this substitution and the pharmacist or client must request the substitution from the health care provider.
The nurse is teaching a class for clients about over-the-counter (OTC) medications. The nurse determines that education has been effective when the clients make which statement? 1. "We should not take any over-the-counter (OTC) medicine without first calling and checking with the doctor's office." 2. "We should always ask the pharmacist about how to take the over-the-counter (OTC) medicine." 3. "We must read all the directions on the label and call the doctor's office if they are not clear." 4. "Medicines that are available over-the-counter (OTC) are really safe, or they would be prescription medicines."
Correct Answer: 3. In most cases, clients may treat themselves safely if they carefully follow instructions included with the medication. It is not realistic to expect clients to call the doctor's office before taking any over-the-counter (OTC) medicine. Most OTC medicines have a high margin of safety, but none is considered completely safe. Asking the pharmacist is a good idea, but does not replace reading the label directions. Also, the pharmacist might not always be in the store when the medicine is purchased.
How many years does it generally take to research and develop a drug before it is submitted to the FDA for review? 1. 6 years 2. 5 years 3. 11 years 4. 9 years
Correct Answer: 3. PharmFacts (p.16)
A patient with chronic back pain informs the nurse he has been receiving therapeutic touch in addition to his medications. This type of therapy is best classified as 1. pharmacotherapy. 2. drug-absence therapy. 3. complementary therapy. 4. biologic therapy.
Correct Answer: 3. The patient is using a non-conventional type of treatment (therapeutic touch) that is classified as complimentary to his conventional pharmacotherapy. Biologic therapy involves the use of naturally produced substances by microorganisms or within the body. The patient is using medications as well as an alternative therapy which is why complementary therapy is the best choice.
During pharmacology class, the student nurse asks the nursing instructor how students will ever learn about the individual antibiotic drugs since there are so many. What is the best response by the nursing instructor? 1. "You will learn a little trick called mnemonics." 2. "You will learn how to do a flow chart to enhance memory." 3. "You will learn how to categorize the individual drugs." 4. "You will learn a representative drug from each class."
Correct Answer: 4 A prototype, or representative, drug is the well-understood drug model from which other drugs in a pharmacological class are compared. Categorizing individual drugs is not the best way to learn about drugs. Using mnemonics is not the best way to learn about drugs. Flow charts are not the best way to learn about drugs.
The client comes to the emergency department with a myocardial infarction. The client's husband tells the nurse that his wife has been taking calcium carbonate (Tums) for years for what she thought was indigestion. What is the best response by the nurse? 1. "Your wife should not have self-diagnosed herself. I hope she will be okay." 2. "Why did you let her do that? She should have seen a doctor." 3. "Well, I am glad she is here, as it certainly wasn't indigestion." 4. "Your wife was self-diagnosing, which is generally not a good idea."
Correct Answer: 4 Clients take over-the-counter (OTC) drugs for many reasons. Self-treatment is sometimes ineffective, and the potential for harm may increase if the disease is allowed to progress. Asking the husband why he let his wife take Tums is non-therapeutic and too accusatory; do not ask "why" questions. Telling the husband that "it certainly wasn't indigestion" is judgmental and will alienate the client and husband. Telling the husband "I hope she will be okay" is a very frightening response that implies she might die, and this is non-therapeutic.
The nurse is employed by the Food and Drug Administration (FDA), and is involved in clinical investigation. What is the primary role of the nurse in this phase of the review and approval process by the FDA? 1. To perform tests on the population-at-large 2. To perform tests on various species of animals 3. To perform tests on human cells cultured in the laboratory 4. To perform tests on human clients
Correct Answer: 4 Clinical investigation includes performing tests on healthy volunteers, and later, on selected clients with a particular disease. Performing tests on human cells cultured in the laboratory is the preclinical investigation stage. Performing tests on the population-at-large is the stage of post-marketing surveillance. Performing tests on various species of animals is the preclinical investigation stage.
Five milliliters is equivalent to 1. 2 tablespoons. 2. 1 fluid ounce. 3. 15 drops. 4. 1 teaspoon.
Correct Answer: 4 Conversion from the metric system (p. 25)
The student nurse asks the nursing instructor why he needs to take anatomy and physiology, as well as microbiology, when he only wants to learn about pharmacology. What is the best response by the instructor? 1. "Because pharmacology is an outgrowth of those subjects." 2. "You must learn all, since those subjects, as well as pharmacology, are part of the curriculum." 3. "Knowledge of all those subjects will prepare you to provide the best patient care, including the administration of medications." 4. "Because an understanding of those subjects is essential to understanding pharmacology."
Correct Answer: 4 It is essential for the nurse to have a broad knowledge base of many sciences in order to learn pharmacology. The nurse must learn anatomy, physiology, and microbiology to understand pharmacology, not because they are part of the curriculum. Pharmacology is an outgrowth of anatomy, physiology, and microbiology, but this is not the reason for the nurse to learn them. Knowledge of anatomy, physiology, and microbiology prepares the nurse to understand pharmacology, not to provide care such as administration of medications.
A patient who recently returned from surgery is experiencing nausea. Which statement best explains why this patient would benefit from IV medication administration? 1. The IV is already in place following the surgery. 2. IV medication administration should be avoided in patients with nausea. 3. Medications are more effective when given IV. 4. IV medications bypass the need for GI absorption.
Correct Answer: 4 Nauseated patients might find medications that need to be absorbed through the GI system irritating, worsening their nausea. The presence of an existing IV line is not a reason to administer medications through it. Some medications are more effective when given IV, but bypassing the need for GI absorption is the better answer.
What is the best plan as the nurse prepares to administer a topical medication? 1. Check the medication for interactions with other medications. 2. Take the patient's vital signs. 3. Educate the patient to not disturb the patch. 4. Assess the patient's skin where the medication will be applied.
Correct Answer: 4 Planning to assess the patient's skin is imperative; if it is cracked, dry, or irritated, the medication may not be properly absorbed. Patient education is important, but is not the priority. Vital signs are not always indicated; it depends on the medication. Checking for drug interactions is important, but it is not the priority.
The nurse teaches a medication class on bronchodilators for clients with asthma. The nurse evaluates that learning has occurred when the clients make which statement? 1. "The medication widens the airways because it decreases the production of mucus that narrows them." 2. "The medication widens the airways because it decreases the production of histamine that narrows them." 3. "The medication widens the airways because it acts on the parasympathetic nervous system." 4. "The medication widens the airways because it stimulates the fight-or-flight response of the nervous system."
Correct Answer: 4 Rationale 1: Bronchodilators do not decrease the production of mucus. Rationale 2: Bronchodilators do not decrease the production of histamine. Rationale 3: Bronchodilators act on the sympathetic nervous system, not the parasympathetic nervous system. Rationale 4: During the fight-or-flight response, beta 2-adrenergic receptors of the sympathetic nervous system are stimulated, the bronchiolar smooth muscle relaxes, and bronchodilation occurs.
The nurse teaches the client about the use of a metered-dose inhaler (MDI) and spacer. The nurse evaluates that additional teaching is required when the client makes which statement? 1. "I need to follow the instructions about using the metered-dose inhaler (MDI)." 2. "I need to rinse my mouth each time after using the metered-dose inhaler (MDI)." 3. "I need to drink a lot of fluids while I am using the metered-dose inhaler (MDI)." 4. "I should keep the spacer moist between uses by storing it in a plastic zip bag.
Correct Answer: 4 Rationale 1: Following instructions indicates compliance with use of the metered-dose inhaler (MDI). Rationale 2: Rinsing the mouth after using the metered-dose inhaler (MDI) is correct; it will help reduce oral absorption of the drug. Rationale 3: Fluids are encouraged to liquefy pulmonary secretions when using the metered-dose inhaler (MDI). Rationale 4: The spacer and inhaler should be rinsed with water and allowed to air-dry.
The nurse plans to teach an adolescent about inhalation therapy as part of the treatment plan for the client's asthma. What does the best plan by the nurse include? 1. Inhalation therapy is effective because it provides around-the-clock therapy, as opposed to oral medications. 2. Inhalation therapy is the preferred treatment for adolescents because it is easier for them to manage. 3. Inhalation therapy is effective because it provides systemic relief of symptoms as well as local relief. 4. Inhalation therapy is effective because it goes to the direct site of action in the respiratory tract.
Correct Answer: 4 Rationale 1: Inhalation therapy does not provide around-the-clock therapy. Rationale 2: Inhalation therapy is used for adolescents because it is effective, not because it is easier for them to manage. Rationale 3: Inhalation therapy does not provide systemic relief of symptoms. Rationale 4: The major advantage of aerosol therapy is that it delivers the drugs to their direct site of action.
The nurse understands that one advantage of inhaled pulmonary drugs over oral drugs is that inhaled drugs 1. increase adverse effects. 2. allow for convenience to the client. 3. are delivered to systemic locations. 4. allow for quick absorption
Correct Answer: 4 Rationale 1: Inhaled drugs decrease adverse effects. Rationale 2: Inhaled drugs are not as convenient as oral. Rationale 3: Inhaled drugs are delivered to local sites. Rationale 4: Inhalation is the most common route of administration; it is rapid and allows for quick absorption to direct airway.
Bronchoconstriction in the airways is stimulated by 1. perfusion. 2. ventilation. 3. the sympathetic nervous system. 4. parasympathetic nervous system.
Correct Answer: 4 Rationale 1: Perfusion is the flow of blood in the lungs. Rationale 2: Ventilation moves air in and out. Rationale 3: The sympathetic nervous system stimulates dilation. Rationale 4: The parasympathetic nervous system stimulates bronchoconstriction
A physician may telephone in an order for which of the following? 1. Morphine 2. Marijuana 3. Cocaine 4. Codeine
Correct Answer: 4 Schedule I and II drugs cannot be ordered via the telephone. Marijuana is a Schedule I drug, and cocaine and morphine are Schedule II drugs, while codeine is a Schedule III drug. (p. 17)
The nurse provides medication education to a client with terminal cancer. The physician has ordered morphine (MS Contin), a Schedule II drug, for the client. The nurse determines that learning has occurred when the client makes which statement? 1. "I need to call the office for a refill before my medication runs out." 2. "This drug is addictive so I should only take it when my pain becomes severe." 3. "Maybe my doctor could change me to a Schedule IV drug." 4. "I need to see my doctor before my prescription runs out so I can get a refill."
Correct Answer: 4 Schedule II drugs cannot be refilled without the client seeing the physician. Not taking pain medication until the pain becomes severe is an inappropriate use of pain medication for a patient with terminal cancer. The client must see the physician for a refill. A Schedule IV drug may not effectively relieve the client's pain.
The mother of an adolescent receiving methylphenidate (Concerta) for attention-deficit hyperactivity disorder tells the nurse that her son is better and asks why she can't just get refills on the prescription. What is the best response by the nurse? 1. "Just drop by and I will get a prescription for you without seeing your son." 2. "We can't do that; maybe you can find another doctor's office that will do it." 3. "The law does not allow us to give you refills on this medication." 4. "The medication can be addictive so your son needs a monthly medical evaluation."
Correct Answer: 4 Telling the mother the reason for monthly evaluations is a therapeutic response that is correct and answers the mother's question. Schedule II medications cannot be refilled without the client being seen by the physician. Telling the mother about the law is accurate, but it is a non-therapeutic response; the mother needs an explanation. Referring the mother to another office is non-therapeutic and implies that other medical offices violate the law.
While discussing antihypertensives, the instructor states that a particular agent causes a reduction in blood pressure by blocking receptor sites. The instructor is describing which of the following? 1. Drug-drug interaction 2. Adverse effects 3. Indication 4. Mechanism of action
Correct Answer: 4 The instructor is describing how a drug produces an effect within the body, which is known as the mechanism of action. Adverse effects are what can result from drug use, not a description of how the drug works. Indications are the reasons the drug is being used, and drug-drug interactions refer to the effects of multiple drug use. (p. 5)
During the admission assessment, the client tells the nurse "Sure I smoke a little weed (marijuana) to manage my stress. Doesn't everyone?" What is the best assessment question for the nurse to ask? 1. "What other ways do you think you might use to help you to manage your stress?" 2. "That is a Schedule I drug; aren't you afraid of going to jail for a long time?" 3. "Do you really believe that everyone smokes marijuana to manage stress?" 4. "How often do you smoke marijuana, and how much each time?"
Correct Answer: 4 The nurse must assess the amount and frequency of any drug the client uses, including illegal drugs. Asking the client if he really believes something is not an assessment question, and can lead to an argument with the client. Stress management is not the main concern during the admission assessment. Asking the client if he is afraid of going to jail is not an assessment question, and is not the issue during the admission assessment.
The presence of muscle tremors following drug cessation would most accurately be associated with which of the following? 1. Adverse effect 2. Psychological dependence 3. Therapeutic effect 4. Physical dependence
Correct Answer: 4 The presence of physical withdrawal symptoms (muscle tremors) is seen when a person is physically dependent on a drug and the drug is removed. With psychological dependence, few physical signs are seen. Therapeutic effects are seen while drugs are being used, not after they have been removed. (p. 16)
Leukotriene modifiers are primarily used for 1. status asthmaticus. 2. infection. 3. bronchodilation in asthma. 4. prophylaxis of asthma symptoms.
Correct Answer: 4 Rationale 1: Leukotrienes are not used for treatment of status asthmaticus. Rationale 2: Leukotrienes do not reduce infection. Rationale 3: Anticholinergics are bronchodilators. Rationale 4: Leukotriene modifiers are used primarily for prophylaxis and reducing inflammatory components.
The nurse would observe for fungal infection of the throat with which class of medications? 1. Methylxanthines 2. Beta-adrenergic agonists 3. Mast cell inhibitors 4. Glucocorticoids
Correct Answer: 4 Rationale 1: Methylxanthines do not cause fungal infection. Rationale 2: Beta-adrenergic agonists can cause throat irritation, but not infection. Rationale 3: Mast cell inhibitors do not cause fungal infection. Rationale 4: Glucocorticoids weaken the immune system and cause candidiasis of the throat.
The client receives zafirlukast (Accolate) as treatment for asthma. The nurse has completed medication education and evaluates that learning has occurred when the client makes which statement? 1. "This medication activates my fight-or-flight response." 2. "This medication is good when I have an acute attack of asthma." 3. "This medication dilates my airways so I can breathe better." 4. "This medication decreases the inflammation in my lungs.
Correct Answer: 4 Rationale 1: Zafirlukast (Accolate) does not stimulate the sympathetic nervous system. Rationale 2: Zafirlukast (Accolate) is ineffective for acute asthma attacks. Rationale 3: Zafirlukast (Accolate) is not a bronchodilator. Rationale 4: Zafirlukast (Accolate) prevents airway edema and inflammation by blocking leukotriene receptors in the airways.
The elderly client has gastrointestinal bleeding. The client says to the nurse "I don't understand this. All I did was take ibuprofen (Advil) for my arthritis." Which plan would be best as it relates to the nurse's education of this client? 1. A plan to teach the client to use drugs that bypass the gastrointestinal system, like topical drugs 2. A plan to teach the client to substitute safer drugs like acetaminophen (Tylenol) 3. A plan to teach the client to obtain physician approval prior to the use of over-the-counter (OTC) medications 4. A plan to teach the advantages and disadvantages of ibuprofen (Advil)
Correct Answer: 4. Since elderly clients account for the use of about 40% of all over-the-counter (OTC) medications, it is essential for the nurse to teach clients about the advantages, and the disadvantages, of these medications. Substitution of other drugs may be beneficial, but this cannot be done in all situations. The use of topical drugs may be an option, but the drug a client needs may not be available in this form. It is not a realistic plan to expect clients to contact their physician prior to taking any over-the-counter (OTC) medication.
Your patient has been diagnosed with heart failure. What breath sound should be assessed by the nurse?
Crackles
A patient with hypertension is taking furosemide [Lasix] for congestive heart failure. The prescriber orders digoxin to help increase cardiac output. What other medication will the nurse expect to be ordered for this patient? a. Bumetanide [Bumex] b. Chlorothiazide [Diuril] c. Hydrochlorothiazide [HydroDIURIL] d. Spironolactone [Aldactone]
D Spironolactone is used in conjunction with furosemide because of its potassium-sparing effects. Furosemide can contribute to hypokalemia, which can increase the risk of fatal dysrhythmias, especially with digoxin administration. The other diuretics listed are all potassium-wasting diuretics.
A nurse preparing to administer morning medications notes that a patient with a history of hypertension has been prescribed spironolactone [Aldactone]. The nurse assesses the patient and notes dyspnea, bilateral crackles, and pitting edema in both feet. Which intervention is appropriate? a. Administer the medications as ordered. b. Ask the patient about the use of salt substitutes. c. Contact the provider to request an order for serum electrolytes. d. Request an order for furosemide [Lasix].
D Spironolactone takes up to 48 hours for its effects to develop, so it should not be used when the patient needs immediate diuresis. This patient has shortness of breath, crackles, and edema and needs a short-acting diuretic, such as furosemide. Asking the patient about the use of salt substitutes is not indicated. The patient does not need assessment of serum electrolytes.
Matching: Fluticasone (Flonase) A. Scabicide/pediculicide B. Sunburn/minor irritation drug C. Acne and acne-related drug D. Topical corticosteroid E. Psoriatic drug
D. Topical corticosteroid
Which class of drugs is most effective in preventing and treating seasonal and perennial rhinitis? A. Antitussives B. Oral antihistamines C. Oral sympathomimetics D. Intranasal glucocorticoids
D. Intranasal glucocorticoids are the most effective drugs for preventing and treating seasonal and perennial rhinitis. They reduce nasal congestion, rhinorrhea, sneezing, nasal itching, and erythema. Antihistamines are less effective than glucocorticoids, because histamine is only one of several mediators of allergic rhinitis. Sympathomimetics relieve only nasal congestion. Antitussives are used to suppress cough.
The client receives beclomethasone (Beconase) intranasally as treatment for allergic rhinitis. He asks the nurse if this drug is safe because it is a glucocorticoid. What is the best response by the nurse? Select one: A. "Intranasal glucocorticoids are safe if they are not used too long." B. "Intranasal glucocorticoids are safe only if used once a day." C. "Intranasal glucocorticoids are safe if you do not swallow any while using them." D. "Intranasal glucocorticoids produce almost no serious adverse effects."
D. "Intranasal glucocorticoids produce almost no serious adverse effects."
The patient has generalized anxiety disorder. He asks the nurse, "Will I need medication for this? My neighbor is very nervous and he takes medication." What is the best response by the nurse? Select one: A. "Medications are a way of life for patients with anxiety disorders." B. "Medication is necessary initially; later we will try therapy." C. "Probably not, but you shouldn't compare yourself to your neighbor." D. "Medication is necessary when anxiety interferes with your quality of life."
D. "Medication is necessary when anxiety interferes with your quality of life."
A patient with a history of heart failure will be started on spironolactone (Aldactone). Which of the following drug groups should not be used, or used with extreme caution in patients taking potassium-sparing diuretics? A: Nonsteroidal anti-inflammatory drugs B: Corticosteroids C: Loop diuretics D: Angiotensin-converting enzyme inhibitors or angiotensin-receptor blockers
D. ACE inhibitors and ARBs taken concurrently with potassium-sparing diuretics increase the risk of hyperkalemia. Options A, B, and C are incorrect. NSAIDs are used cautiously with all diuretics because they are excreted through the kidney. Corticosteroids and loop diuretics may cause hypokalemia and may be paired with a potassium-sparing diuretic to reduce the risk of hypokalemia developing if a diuretic is needed.
Which of the following treatments would NOT be used to promote the shedding of old skin? A. Resorcinol B. Salicylic acid C. Sulfur D. Benzoyl peroxide
D. Benzoyl peroxide
The nurse is caring for a 72-year-old patient taking gabapentin (Gralise, Horizant, Neurontin) for a seizure disorder. Because of this patient's age, the nurse would establish which nursing diagnosis related to the drug's common adverse effects? A. Risk for Deficient Fluid Volume B. Risk for Impaired Verbal Communication C. Risk for Constipation D. Risk for Falls
D. CNS depression including dizziness and drowsiness is a common adverse effect of gabapentin (Gralise, Horizant, Neurontin). Because of this patient's age, these effects may increase the risk of falls. Options A, B, and C are incorrect. The drug is not known to cause dehydration (fluid volume deficit) or constipation or impair the ability to communicate.
Teaching for a patient receiving carbamazepine (Tegretol) should include instructions that the patient should immediately report which symptom? A. Leg cramping B. Blurred vision C. Lethargy D. Blister-like rash
D. Carbamazepine (Tegretol) is associated with Stevens-Johnson syndrome and exfoliative dermatitis. A blister-like skin rash may indicate that these conditions are developing. Options A, B, and C are incorrect. Blurred vision, leg cramping, and drowsiness or lethargy are adverse effects of carbamazepine but do not require immediate reporting and may diminish over time.
Which of the following is contraindicated in conjunction with phototherapy for the treatment of psoriasis? A. Tar and anthralin B. Keratolytic pastes C. Psoralens D. Cyclosporine
D. Cyclosporine
The nurse instructs a patient receiving phenytoin (Dilantin) to visit the dentist regularly and perform frequent oral hygiene. What common adverse effect is the nurse educating the patient about for this medication? A. Oral candidiasis B. Increased incidence of dental caries C. Increased risk of tooth abscess D. Gingival hyperplasia

What is the most likely response in the patient? Select one: A. A marked decrease in serum glucose levels will most likely occur. B. Nothing adverse, the medication may be administered intravenously (IV) or intramuscularly (IM). C. A phenomenon known as purple gluteus syndrome will most likely occur. D. Local tissue damage following extravasation will most likely occur.
D. Local tissue damage following extravasation will most likely occur.
Education given to patients about the use of all drugs to treat insomnia should include an emphasis on what important issue? A. They will be required long-term to achieve lasting effects. B. They require frequent blood counts to avoid adverse effects. C. They are among the safest drugs available and have few adverse effects. D. Long-term use may increase the risk of adverse effects, create a "sleep debt," and cause rebound insomnia when stopped.
D. Long-term use of drugs to treat insomnia is not recommended. They have significant adverse effects, may cause a "sleep debt" due to effects on the sleep cycle, and may cause rebound insomnia when discontinued. Options A, B, and C are incorrect. Many of the drugs used for insomnia have significant adverse effects and are not used long term. Whereas some drugs in the category may require concurrent blood counts, this is not required for all drugs in the category.

A patient is receiving temazepam (Restoril). Which of these responses should a nurse expect the patient to have if the medication is achieving the desired effect? A. The patient sleeps in 3-hour intervals, awakens for a short time, and then falls back to sleep. B. The patient reports feeling less anxiety during activities of daily living. C. The patient reports having fewer episodes of panic attacks when stressed. D. The patient reports sleeping 7 hours without awakening.
D. Temazepam (Restoril) is a benzodiazepine ordered for insomnia. Therefore, the patient should be experiencing relief from insomnia and reporting feeling rested when awakening. Options A, B, and C are incorrect. Sleeping 3 hours or less would indicate less than therapeutic effects. Whereas some benzodiazepines are used in the treatment of anxiety or panic disorders, temazepam's primary use is in the treatment of insomnia.
The patient has been receiving escitalopram (Lexapro) for treatment of obsessive-compulsive disorder. Unknown to the nurse, the patient has also been self-medicating with St. John's wort. The patient comes to the office with symptoms of hyperthermia and diaphoresis. Which statement best describes the result of the nurse's assessment? Select one: A. The patient is experiencing symptoms of St. John's wort toxicity, as the medication was most likely outdated. B. The patient has not been taking escitalopram (Lexapro) and is experiencing withdrawal. C. The patient has contracted a viral infection. Escitalopram (Lexapro) and St. John's wort are safe to take together. D. The patient has combined two antidepressant medications and is experiencing serotonin syndrome.
D. The patient has combined two antidepressant medications and is experiencing serotonin syndrome.
A patient has been using a fluticasone (Flovent) inhaler as a component of his asthma therapy. He returns to his health care provider's office complaining of a sore mouth. On inspection, the nurse notices white patches in the patient's mouth. What is a possible explanation for these findings? A. The patient has been consuming hot beverages after the use of the inhaler. B. The patient has limited his fluid intake, resulting in dry mouth. C. The residue of the inhaler propellant is coating the inside of the mouth. D. The patient has developed thrush as a result of the fluticasone.
D. The patient likely has developed a thrush (Candida) infection of the mouth secondary to the use of the corticosteroid inhaler. After the use of ICS inhalers such as fluticasone (Flovent), patients should be taught to rinse the mouth and spit out the residue. Drinking fluids will also prevent irritation, ulcerations, and thrush infections of the throat. Options A, B, and C are incorrect. Drinking hot liquids should be managed carefully but will not increase the incidence of adverse effects due to the inhaler. Fluids in general should be increased but dry mouth should not result in white patches. The propellant should not remain in the patient's mouth after rinsing, eating, or drinking.
An individual who has difficulty sleeping due to two final examinations scheduled for the same day later in the week most likely would be suffering from Select one: A. social anxiety. B. performance anxiety. C. obsessive-compulsive disorder. D. situational anxiety.
D. situational anxiety.
The nurse is teaching a patient about the use of dextromethorphan with guaifenesin (Robitussin-DM) syrup for a cough accompanied by thick mucus. Which instruction should be included in the patient's teaching? A: Lie supine for 30 minutes after taking the liquid. B: Drink minimal fluids to avoid stimulating the cough reflex. C: Take the drug with food for best results. D: Avoid drinking fluids immediately after the syrup but increase overall fluid intake throughout the day.
D: The syrup base of dextromethorphan will help soothe throat irritation, and fluids should be avoided immediately following administration. Overall fluid intake should be increased throughout the day. Options A, B, and C are incorrect. The patient does not need to remain supine after taking this drug, take the drug with food, or avoid fluid intake.
The nurse is planning teaching for a patient prescribed desoximetasone (Topicort) for atopic dermatitis. The nurse will teach the patient to anticipate which possible adverse effects? A: Localized pruritis and hives B: Hair loss in the application area C: Worsening of acne D: Burning and stinging of the skin in the affected area
D: Topical reactions such as burning or stinging in the area topical corticosteroids such as desoximetasone (Topicort) are applied are common. Options A, B, and C are incorrect. The drug should not cause hair loss or worsening of acne. If pruritus and hives occur, they should be evaluated as signs of possible allergy to the cream.
The parents of a client receiving methylphenidate (Ritalin) express concern that the health care provider has suggested that the child have a "holiday" from the drug. The nurse explains that the drug-free holiday is designed to: Reduce the risk of drug toxicity. Decrease drug dependence and assess status. Prevent hypertensive crisis. Allow the child's "normal" behavior to return.
Decrease drug dependence and assess status. Objective: For each of the drug classes listed in Drugs at a Glance, know representative drug examples, and explain their mechanisms of action, primary actions, and important adverse effects. Rationale: Methylphenidate (Ritalin) is a Schedule II drug with the potential to cause drug dependence when used over an extended period of time. The drug holiday is to decrease the risk of dependence and to evaluate behavior.

Which of the following symptoms are seen when a client abruptly stops taking diazepam (Valium)? Select all that apply. 1. Insomnia. 2. Tremor. 3. Delirium. 4. Dry mouth. 5. Lethargy.
Diazepam (Valium) is a benzodiazepine. Benzodiazepines are physiologically and psychologically addictive. If a benzodiazepine is stopped abruptly, a rebound stimulation of the central nervous system occurs, and the client may experience insomnia, increased anxiety, abdominal and muscle cramps, tremors, vomiting, sweating, convulsions, and delirium. 1. Insomnia is correct. 2. Tremor is correct. 3. Delirium is correct. 4. Dry mouth is a side effect of taking benzodiazepines and is not related to stopping the medication abruptly. 5. Lethargy is a side effect of taking benzodiazepines and is not related to stopping the medication abruptly. TEST-TAKING HINT: The test taker must distinguish between benzodiazepine side effectsand symptoms of withdrawal to answer this question correctly.

An older adult taking digoxin and furosemide (Lasix) for chronic heart failure is admitted to the emergency department (ED) with an apical pulse of 52. A family member states that the client has fallen four times this week. What is the nurse's first action? a. Call the ED physician immediately. b. Draw a serum digoxin level. c. Assess for signs of hypokalemia. d. Establish the client's airway.
p. 753, Physiological Integrity Answer: Draw a serum digoxin level Rationale: The client has signs and symptoms of digoxin toxicity and needs to be placed on a monitor immediately to determine the extent of effects on the heart and conduction system. Symptoms of digoxin toxicity include blurred vision or yellow or green halos around visual images, confusion, muscle weakness, and vertigo. Toxicity may be increased from furosemide-induced hypokalemia. This can lead to premature ventricular contractions (PVCs) that may lead to other life-threatening dysrhythmias and death. Clients need to be cautioned not to store both digoxin and furosemide in the same container. The most common dose of each medication is available in a small white pill (similar in appearance), increasing the chances of error.
