NCLEX Review Quiz 5 Saunder's Questions (Ch. 42, 43, 58-61)

711. The nurse would evaluate that defibrillation of a client was most successful if which observation was made? 1. Arousable, sinus rhythm, BP 116/72 mm Hg 2. Nonarousable, sinus rhythm, BP 88/60 mm Hg 3. Arousable, marked bradycardia, BP 86/54 mm Hg 4. Nonarousable, supraventricular tachycardia, BP 122/60 mm Hg

1 After defibrillation, the client requires continuous monitoring of electrocardiographic rhythm, hemodynamic status, and neurological status. Respiratory and metabolic acidosis develop during ventricular fibrillation because of lack of respiration and cardiac output. These can cause cerebral and cardiopulmonary complications. Arousable status, adequate blood pressure, and a sinus rhythm indicate successful response to defibrillation.

715. The nurse is assessing the neurovascular status of a client who returned to the surgical nursing unit 4 hours ago after undergoing aortoiliac bypass graft. The affected leg is warm, and the nurse notes redness and edema. The pedal pulse is palpable and unchanged from admission. How should the nurse correctly interpret the client's neurovascular status? 1. The neurovascular status is normal because of increased blood flow through the leg. 2. The neurovascular status is moderately impaired, and the surgeon should be called. 3. The neurovascular status is slightly deteriorating and should be monitored for another hour. 4. The neurovascular status is adequate from an arterial approach, but venous complications are arising.

1 An expected outcome of aortoiliac bypass graft surgery is warmth, redness, and edema in the surgical extremity because of increased blood flow. The remaining options are incorrect interpretations.

694. The nurse is caring for a client with a diagnosis of influenza who first began to experience symptoms yesterday. Antiviral therapy is prescribed and the nurse provides instructions to the client about the therapy. Which statement by the client indicates an understanding of the instructions? 1. "I must take the medication exactly as prescribed." 2. "Once I start the medication, I will no longer be contagious." 3. "I will not get any colds or infections while taking this medication." 4. "This medication has minimal side effects and I can return to normal activities."

1 Antiviral medications for influenza must be taken exactly as prescribed. These medications do not prevent the spread of influenza and clients are usually contagious for up to 2 days after the initiation of antiviral medications. Secondary bacterial infections may occur despite antiviral treatment. Side effects occur with these medications and may necessitate change in activities, especially when driving or operating machinery if dizziness occurs.

708. The nurse is watching the cardiac monitor, and a client's rhythm suddenly changes. There are no P waves; instead, there are fibrillatory waves before each QRS complex. How should the nurse correctly interpret the client's heart rhythm? 1. Atrial fibrillation 2. Sinus tachycardia 3. Ventricular fibrillation 4. Ventricular tachycardia

1 Atrial fibrillation is characterized by a loss of P waves and fibrillatory waves before each QRS complex. The atria quiver, which can lead to thrombus formation.

695. A client is admitted to an emergency department with chest pain that is consistent with myocardial infarction based on elevated troponin levels. Heart sounds are normal and vital signs are noted on the client's chart. The nurse should alert the health care provider because these changes are most consistent with which complication? Refer to chart. (pg 812) 1. Cardiogenic shock 2. Cardiac tamponade 3. Pulmonary embolism 4. Dissecting thoracic aortic aneurysm

1 Cardiogenic shock occurs with severe damage (more than 40%) to the left ventricle. Classic signs include hypotension, a rapid pulse that becomes weaker, decreased urine output, and cool, clammy skin. Respiratory rate increases as the body develops metabolic acidosis from shock. Cardiac tamponade is accompanied by distant, muffled heart sounds and prominent neck vessels. Pulmonary embolism presents suddenly with severe dyspnea accompanying the chest pain. Dissecting aortic aneurysms usually are accompanied by back pain.

438. The nurse is closely monitoring the intake and output of an infant with heart failure who is receiving diuretic therapy. The nurse should use which most appropriate method to assess the urine output? 1. Weighing the diapers 2. Inserting a Foley catheter 3. Comparing intake with output 4. Measuring the amount of water added to formula

1 HF is the inability of the heart to pump a sufficient amount of blood to meet the oxygen and metabolic needs of the body. The most appropriate method for assessing urine output in an infant receiving diuretic therapy is to weigh the diapers. Comparing intake with output would not provide an accurate measure of urine output. Measuring the amount of water added to the formula is unrelated to the amount of output. Although Foley catheter drainage is most accurate in determining output, it is not the most appropriate method in an infant and places the infant at risk for infection.

671. A client with acquired immunodeficiency syndrome (AIDS) has histoplasmosis. The nurse should assess the client for which expected finding? 1. Dyspnea 2. Headache 3. Weight gain 4. Hypothermia

1 Histoplasmosis is an opportunistic fungal infection that can occur in the client with acquired immunodeficiency syndrome (AIDS). The infection begins as a respiratory infection and can progress to disseminated infection. Typical signs and symptoms include fever, dyspnea, cough, and weight loss. Enlargement of the client's lymph nodes, liver, and spleen may occur as well.

430. The clinic nurse reads the results of a tuberculin skin test on a 3 y/o child. The results indicate an area of induration measuring 10 mm. The nurse should interpret these results as which finding? 1. Positive 2. Negative 3. Inconclusive 4. Definitive and requiring a repeat test

1 Induration measuring 10 mm or more is considered to be a positive result in children younger than 4 years of age and in children with chronic illness or a high risk for exposure to tuberculosis. A reaction of 5 mm or more is considered a positive result for the highest risk groups, such as a child with an immunosuppressive condition or a child with HIV infection. A reaction of 15 mm or more is positive in children under 4 years without any risk factors.

664. A client has been admitted with chest trauma after a motor vehicle crash and has undergone subsequent intubation. The nurse checks the client when the high-pressure alarm on the ventilator sounds, and notes that the client has absence of breath sounds in the right upper lobe of the lung. The nurse immediately assesses for other signs of which condition? 1. Right pneumothorax 2. Pulmonary embolism 3. Displaced endotracheal tube 4. Acute respiratory distress syndrome

1 Pneumothorax is characterized by restlessness, tachycardia, dyspnea, pain with respiration, asymmetrical chest expansion, and diminished or absent breath sounds on the affected side. Pneumothorax can cause increased airway pressure because of resistance to lung inflation. Acute respiratory distress syndrome and pulmonary embolism are not characterized by absent breath sounds. An endotracheal tube that is inserted too far can cause absent breath sounds, but the lack of breath sounds most likely would be on the left side because of the degree of curvature of the right and left mainstem bronchi.

673. The nurse is taking the history of a client with occupational lung disease (silicosis). The nurse should assess whether the client wears which item during periods of exposure to silica particles? 1. Mask 2. Gown 3. Gloves 4. Eye protection

1 Silicosis results from chronic, excessive inhalation of particles of free crystalline silica dust. The client should wear a mask to limit inhalation of this substance, which can cause restrictive lung disease after years of exposure. Options 2, 3, and 4 are not necessary.

670. A client who is human immunodeficiency virus (HIV)-positive has had a tuberculin skin test (TST). The nurse notes a 7-mm area of induration at the site of the skin test and interprets the result as which finding? 1. Positive 2. Negative 3. Inconclusive 4. Need for repeat testing

1 The client with human immunodeficiency virus (HIV) infection is considered to have positive results on tuberculin skin testing with an area of induration larger than 5 mm. The client without HIV is positive with an induration larger than 10 mm. The client with HIV is immunosuppressed, making a smaller area of induration positive for this type of client. It is possible for the client infected with HIV to have false-negative readings because of the immunosuppression factor. Options 2, 3, and 4 are incorrect interpretations.

692. A client has begun therapy with theophylline. The nurse should plan to teach the client to limit the intake of which items while taking this medication? 1. Coffee, cola, and chocolate 2. Oysters, lobster, and shrimp 3. Melons, oranges, and pineapple 4. Cottage cheese, cream cheese, and dairy creamers

1 Theophylline (Theo-24) is a methylxanthine bronchodilator. The nurse teaches the client to limit the intake of xanthinecontaining foods while taking this medication. These foods include coffee, cola, and chocolate.

722. A client who is receiving digoxin daily has a serum potassium level of 3 mEq/L and is complaining of anorexia. The health care provider prescribes determination of the serum digoxin level to rule out digoxin toxicity. The nurse checks the results, knowing that which value is the therapeutic serum level (range) for digoxin? 1. 0.5 to 2 ng/mL 2. 1.2 to 2.8 ng/mL 3. 3.0 to 5.0 ng/mL 4. 3.5 to 5.5 ng/mL

1 Therapeutic levels for digoxin range from 0.5 to 2 ng/mL. The ranges in the remaining options are incorrect.

705. A client has frequent bursts of ventricular tachycardia on the cardiac monitor. What should the nurse be most concerned about with this dysrhythmia? 1. It can develop into ventricular fibrillation at any time. 2. It is almost impossible to convert to a normal rhythm. 3. It is uncomfortable for the client, giving a sense of impending doom. 4. It produces a high cardiac output that quickly leads to cerebral and myocardial ischemia.

1 Ventricular tachycardia is a life-threatening dysrhythmia that results from an irritable ectopic focus that takes over as the pacemaker for the heart. The low cardiac output that results can lead quickly to cerebral and myocardial ischemia. Clients frequently experience a feeling of impending doom. Ventricular tachycardia is treated with antidysrhythmic medications, cardioversion (if client is awake), or defibrillation (loss of consciousness). Ventricular tachycardia can deteriorate into ventricular fibrillation at any time.

681. The nurse teaches a client about the effects of diphenhydramine, which has been prescribed as a cough suppressant. The nurse determines that the client needs further instruction if the client makes which statement? 1. "I will take the medication on an empty stomach." 2. "I won't drink alcohol while taking this medication." 3. "I will use sugarless gum, candy, or oral rinses to decrease dryness in my mouth." 4. "I won't do activities that require mental alertness while taking this medication."

1 Diphenhydramine (Benadryl) has several uses, including as an antihistamine, antitussive, antidyskinetic, and sedativehypnotic. Instructions for use include taking with food or milk to decrease gastrointestinal upset and using oral rinses or sugarless gum or hard candy to minimize dry mouth. Because the medication causes drowsiness, the client should avoid use of alcohol or central nervous system depressants, operating a car, or engaging in other activities requiring mental awareness during use.

698. The nurse in a medical unit is caring for a client with heart failure. The client suddenly develops extreme dyspnea, tachycardia, and lung crackles and the nurse suspects pulmonary edema. The nurse immediately asks another nurse to contact the health care provider and prepares to implement which priority interventions? Select all that apply. 1. Administering oxygen 2. Inserting a Foley catheter 3. Administering furosemide (Lasix) 4. Administering morphine sulfate intravenously 5. Transporting the client to the coronary care unit 6. Placing the client in a low Fowler's side-lying position

1, 2, 3, 4 Pulmonary edema is a life-threatening event that can result from severe heart failure. In pulmonary edema, the left ventricle fails to eject sufficient blood, and pressure increases in the lungs because of the accumulated blood. Oxygen is always prescribed, and the client is placed in a high Fowler's position to ease the work of breathing. Furosemide, a rapid-acting diuretic, will eliminate accumulated fluid. A Foley catheter is inserted to measure output accurately. Intravenously administered morphine sulfate reduces venous return (preload), decreases anxiety, and also reduces the work of breathing. Transporting the client to the coronary care unit is not a priority intervention. In fact, this may not be necessary at all if the client's response to treatment is successful.

691. Rifabutin is prescribed for a client with active Mycobacterium avium complex (MAC) disease and tuberculosis. For which side/adverse effects of the medication should the nurse monitor? Select all that apply. 1. Signs of hepatitis 2. Flulike syndrome 3. Low neutrophil count 4. Vitamin B6 deficiency 5. Ocular pain or blurred vision 6. Tingling and numbness of the fingers

1, 2, 3, 5 Rifabutin (Mycobutin) may be prescribed for a client with active Mycobacterium avium complex (MAC) disease and tuberculosis. It inhibits mycobacterial DNA-dependent RNA polymerase and suppresses protein synthesis. Side/adverse effects include rash, gastrointestinal disturbances, neutropenia (low neutrophil count), red-orange-colored body secretions, uveitis (blurred vision and eye pain), myositis, arthralgia, hepatitis, chest pain with dyspnea, and flulike syndrome. Vitamin B6 deficiency and numbness and tingling in the extremities are associated with the use of isoniazid. Ethambutol (Myambutol) causes peripheral neuritis.

658. The nurse is preparing a list of home care instructions for a client who has been hospitalized and treated for tuberculosis. Which instructions should the nurse include on the list? Select all that apply. 1. Activities should be resumed gradually. 2. Avoid contact with other individuals, except family members, for at least 6 months. 3. A sputum culture is needed every 2 to 4 weeks once medication therapy is initiated. 4. Respiratory isolation is not necessary because family members already have been exposed. 5. Cover the mouth and nose when coughing or sneezing and put used tissues in plastic bags. 6. When one sputum culture is negative, the client is no longer considered infectious and usually can return to former employment.

1, 3, 4, 5 The nurse should provide the client and family with information about tuberculosis and allay concerns about the contagious aspect of the infection. Instruct the client to follow the medication regimen exactly as prescribed and always to have a supply of the medication on hand. Advise the client of the side effects of the medication and ways of minimizing them to ensure compliance. Reassure the client that after 2 to 3 weeks of medication therapy, it is unlikely that the client will infect anyone. Inform the client that activities should be resumed gradually and about the need for adequate nutrition and a well-balanced diet that is rich in iron, protein, and vitamin C to promote healing and prevent recurrence of infection. Inform the client and family that respiratory isolation is not necessary because family members already have been exposed. Instruct the client about thorough hand washing and to cover the mouth and nose when coughing or sneezing and to put used tissues into plastic bags. Inform the client that a sputum culture is needed every 2 to 4 weeks once medication therapy is initiated. When the results of three sputum cultures are negative, the client is no longer considered infectious and can usually return to former employment.

433. The nurse is preparing for the admission of an infant with a diagnosis of bronchiolitis caused by respiratory syncytial virus. Which interventions should the nurse include in the plan of care? Select all that apply. 1. Place the infant in a private room 2. Ensure that the infant's head is in a flexed position 3. Wear a mask at all times when in contact with the infant 4. Place the infant in a tent that delivers warm humidified air 5. Position the infant on the side, with the head lower than the chest 6. Ensure the nurses caring for the infant with RSV do not care for other high-risk children

1, 6 RSV is a highly communicable disorder and is not transmitted via the airborne route. The virus usually is transferred by the hands. Use of contact and standard precautions during care (wearing gloves and a gown) reduces nosocomial transmission of RSV. A mask is unnecessary. In addition, it is important to ensure that nurses caring for a child with RSV do not care for other high-risk children to prevent the transmission of infection. An infant with RSV is isolated in a single room or placed in a room with another child with RSV. The infant should be positioned with the head and chest at a 30-40 degree angle and the neck slightly extended to maintain an open airway and decrease pressure on the diaphragm. Cool humidified oxygen is delivered to relieve dyspnea, hypoxemia, and insensible water loss from tachypnea.

424. A 10 y/o child with asthma is treated for acute exacerbation in the ED. The nurse caring for the child should monitor for which sign, knowing that it indicates a worsening of the condition? 1. Warm, dry skin 2. Decreased wheezing 3. Pulse rate of 90 beats/min 4. Respirations of 18 breaths/min

2 Asthma is a chronic inflammatory disease of the airways. Decreased wheezing in a child with asthma may be interpreted incorrectly as a positive sign when it may actually signal an inability to move air. A "silent chest" is an ominous sign during an asthma-episode. With treatment, increased wheezing actually may signal that the child's condition is improving. Warm, dry skin indicates an improvement in the child's condition because the child is normally diaphoretic during exacerbation. The normal pulse rate in a 10 y/o is 70 to 110 beats/min. The normal respiratory rate in a 10 y/o is 16 to 20 breaths/min.

724. The nurse is monitoring a client who is taking propranolol. Which assessment data indicates a potential serious complication associated with this medication? 1. The development of complaints of insomnia 2. The development of audible expiratory wheezes 3. A baseline blood pressure of 150/80 mm Hg followed by a blood pressure of 138/72 mm Hg after two doses of the medication 4. A baseline resting heart rate of 88 beats/minute followed by a resting heart rate of 72 beats/minute after two doses of the medication

2 Audible expiratory wheezes may indicate a serious adverse reaction, bronchospasm. β-Blockers may induce this reaction, particularly in clients with chronic obstructive pulmonary disease or asthma. Normal decreases in blood pressure and heart rate are expected. Insomnia is a frequent mild side effect and should be monitored.

666. The nurse is discussing the techniques of chest physiotherapy and postural drainage (respiratory treatments) to a client having expectoration problems because of chronic thick, tenacious mucus production in the lower airway. The nurse explains that after the client is positioned for postural drainage the nurse will perform which action to help loosen secretions? 1. Palpation and clubbing 2. Percussion and vibration 3. Hyperoxygenation and suctioning 4. Administer a bronchodilator and monitor peak flow

2 Chest physiotherapy of percussion and vibration helps loosen secretions in the smaller lower airways. Postural drainage positions the client so that gravity can help mucus moving from smaller airways to larger ones to support expectoration of the mucus. Options 1, 3, and 4 are not actions that will loosen secretions.

700. A client with myocardial infarction is developing cardiogenic shock. Because of the risk of myocardial ischemia, what condition should the nurse carefully assess the client for? 1. Bradycardia 2. Ventricular dysrhythmias 3. Rising diastolic blood pressure 4. Falling central venous pressure

2 Classic signs of cardiogenic shock as they relate to myocardial ischemia include low blood pressure and tachycardia. The central venous pressure would rise as the backward effects of the severe left ventricular failure became apparent. Dysrhythmias commonly occur as a result of decreased oxygenation and severe damage to greater than 40% of the myocardium.

720. A client with atrial fibrillation is receiving a continuous heparin infusion at 1000 units/hour. The nurse determines that the client is receiving the therapeutic effect based on which results? 1. Prothrombin time of 12.5 seconds 2. Activated partial thromboplastin time of 60 seconds 3. Activated partial thromboplastin time of 28 seconds 4. Activated partial thromboplastin time longer than 120 seconds

2 Common laboratory ranges for activated partial thromboplastin time are 20 to 36 seconds. Because the activated partial thromboplastin time should be 1.5 to 2.5 times the normal value, the client's activated partial thromboplastin time would be considered therapeutic if it was 60 seconds.

428. The ED nurse is caring for a child diagnosed with epiglottitis. In assessing the child, the nurse should monitor for which indication that the child may be experiencing airway obstruction? 1. The child exhibits nasal flaring and bradycardia 2. The child is leaning forward with the chin thrust out 3. The child has a low-grade fever and complains of a sore throat 4. The child is leaning backward, supporting himself or herself with the hands and arms

2 Epiglottitis is a bacterial form of croup. A primary concern is that it can progress to acute respiratory disease. Clinical manifestations suggestive of airway obstruction include tripod positioning (leaning forward while supported by arms, chin thrust out, mouth open), nasal flaring, the use of accessory muscles for breathing, and the presence of stridor. Option 4 is an incorrect position. Option 1 and 3 are incorrect because epiglottis causes tachycardia and a high fever.

717. The nurse is caring for a client who had a resection of an abdominal aortic aneurysm yesterday. The client has an intravenous infusion at a rate of 150 mL/hour, unchanged for the last 10 hours. The client's urine output for the last 3 hours has been 90, 50, and 28 mL (28 mL most recent). The client's blood urea nitrogen level is 35 mg/dL and the serum creatinine level is 1.8 mg/dL, measured this morning. Which nursing action is the priority? 1. Check the urine specific gravity. 2. Call the health care provider (HCP). 3. Check to see if the client had a sample for a serum albumin level drawn. 4. Put the intravenous (IV) line on a pump so that the infusion rate is sure to stay stable.

2 Following abdominal aortic aneurysm resection or repair, the nurse monitors the client for signs of acute kidney injury. Acute kidney injury can occur because often much blood is lost during the surgery and, depending on the aneurysm location, the renal arteries may be hypoperfused for a short period during surgery. Options 1 and 3 are not associated with the data in the question. The IV should have already been on a pump. Urine output lower than 30 mL/hour is reported to the HCP.

685. A client has been taking isoniazid for 11⁄2 months. The client complains to the nurse about numbness, paresthesias, and tingling in the extremities. The nurse interprets that the client is experiencing which problem? 1. Hypercalcemia 2. Peripheral neuritis 3. Small blood vessel spasm 4. Impaired peripheral circulation

2 Isoniazid is an antitubercular medication. A common side effect of isoniazid is peripheral neuritis, manifested by numbness, tingling, and paresthesias in the extremities. This can be minimized with pyridoxine (vitamin B6) intake. Options 1, 3, and 4 are incorrect.

686. A client is to begin a 6-month course of therapy with isoniazid. The nurse should plan to teach the client to take which action? 1. Use alcohol in small amounts only. 2. Report yellow eyes or skin immediately. 3. Increase intake of Swiss or aged cheeses. 4. Avoid vitamin supplements during therapy.

2 Isoniazid is hepatotoxic, and therefore the client is taught to report signs and symptoms of hepatitis immediately, which include yellow skin and sclera. For the same reason, alcohol should be avoided during therapy. The client should avoid intake of Swiss cheese, fish such as tuna, and foods containing tyramine because they may cause a reaction characterized by redness and itching of the skin, flushing, sweating, tachycardia, headache, or lightheadedness. The client can avoid developing peripheral neuritis by increasing the intake of pyridoxine (vitamin B6) during the course of isoniazid therapy.

712. The nurse is evaluating a client's response to cardioversion. Which observation would be of highest priority to the nurse? 1. Blood pressure 2. Status of airway 3. Oxygen flow rate 4. Level of consciousness

2 Nursing responsibilities after cardioversion include maintenance first of a patent airway, and then oxygen administration, assessment of vital signs and level of consciousness, and dysrhythmia detection.

699. A client with myocardial infarction suddenly becomes tachycardic, shows signs of air hunger, and begins coughing frothy, pink-tinged sputum. Which finding would the nurse anticipate when auscultating the client's breath sounds? 1. Stridor 2. Crackles 3. Scattered rhonchi 4. Diminished breath sounds

2 Pulmonary edema is characterized by extreme breathlessness, dyspnea, air hunger, and the production of frothy, pinktinged sputum. Auscultation of the lungs reveals crackles. Rhonchi and diminished breath sounds are not associated with pulmonary edema. Stridor is a crowing sound associated with laryngospasm or edema of the upper airway.

432. The nurse is caring for an infant with bronchitis, and diagnostic tests have confirmed respiratory syncytial virus. On the basis of this finding, which is the most appropriate nursing action? 1. Initiate strict enteric precautions 2. Move the infant to a room with another child with RSV 3. Leave the infant in the present room because RSV is not contagious 4. Inform the staff that they must weak a mask, gloves, and a gown when caring for the child

2 RSV is a highly communicable disorder and is not transmitted via the airborne route. The virus usually is transferred by the hands. Use of contact and standard precautions during care is necessary. Using good hand-washing techniques and wearing gloves and gowns are also necessary. Masks are not required. An infant with RSV is isolated in a single room or placed in a room with another child with RSV. Enteric precautions are not necessary.

690. The nurse has a prescription to give a client salmeterol, two puffs, and beclomethasone dipropionate, two puffs, by metered-dose inhaler. The nurse should administer the medication using which procedure? 1. Beclomethasone first and then the salmeterol 2. Salmeterol first and then the beclomethasone 3. Alternating a single puff of each, beginning with the salmeterol 4. Alternating a single puff of each, beginning with the beclomethasone

2 Salmeterol (Serevent Diskus) is an adrenergic type of bronchodilator and beclomethasone dipropionate (Qvar) is a glucocorticoid. Bronchodilators are always administered before glucocorticoids when both are to be given on the same time schedule. This allows for widening of the air passages by the bronchodilator, which then makes the glucocorticoid more effective.

714. A client's electrocardiogram strip shows atrial and ventricular rates of 110 beats/minute. The PR interval is 0.14 second, the QRS complex measures 0.08 second, and the PP and RR intervals are regular. How should the nurse correctly interpret this rhythm? 1. Sinus dysrhythmia 2. Sinus tachycardia 3. Sinus bradycardia 4. Normal sinus rhythm

2 Sinus tachycardia has the characteristics of normal sinus rhythm, including a regular PP interval and normal-width PR and QRS intervals; however, the rate is the differentiating factor. In sinus tachycardia, the atrial and ventricular rates are greater than 100 beats/minute.

674. An oxygen delivery system is prescribed for a client with chronic obstructive pulmonary disease to deliver a precise oxygen concentration. Which oxygen delivery system would the nurse anticipate to be prescribed? 1. Face tent 2. Venturi mask 3. Aerosol mask 4. Tracheostomy collar

2 The Venturi mask delivers the most accurate oxygen concentration. It is the best oxygen delivery system for the client with chronic airflow limitation because it delivers a precise oxygen concentration. The face tent, aerosol mask, and tracheostomy collar are also high-flow oxygen delivery systems but most often are used to administer high humidity.

732. Intravenous heparin therapy is prescribed for a client. While implementing this prescription, the nurse ensures that which medication is available on the nursing unit? 1. Vitamin K 2. Protamine sulfate 3. Potassium chloride 4. Aminocaproic acid

2 The antidote to heparin is protamine sulfate; it should be readily available for use if excessive bleeding or hemorrhage should occur. Vitamin K is an antidote for warfarin sodium. Potassium chloride is administered for a potassium deficit. Aminocaproic acid is the antidote for thrombolytic therapy.

701. A client who had cardiac surgery 24 hours ago has had a urine output averaging 20 mL/hour for 2 hours. The client received a single bolus of 500 mL of intravenous fluid. Urine output for the subsequent hour was 25 mL. Daily laboratory results indicate that the blood urea nitrogen level is 45 mg/dL and the serum creatinine level is 2.2 mg/dL. On the basis of these findings, the nurse would anticipate that the client is at risk for which problem? 1. Hypovolemia 2. Acute kidney injury 3. Glomerulonephritis 4. Urinary tract infection

2 The client who undergoes cardiac surgery is at risk for renal injury from poor perfusion, hemolysis, low cardiac output, or vasopressor medication therapy. Renal injury is signaled by decreased urine output and increased blood urea nitrogen and creatinine levels. The client may need medications to increase renal perfusion and possibly could need peritoneal dialysis or hemodialysis. No data in the question indicate the presence of hypovolemia, glomerulonephritis, or urinary tract infection.

440. The nurse has provided home care instructions to the parents of a child who is being discharged after cardiac surgery. Which statement made by the parents indicates a need for further instructions? 1. "A balance of rest and exercise is important" 2. "I can apply lotion or powder to the incision if it is itchy" 3. "Activities in which my child could fall need to be avoided for 2-4 weeks 4. "Large crowds of people need to be avoided for at least 2 weeks after surgery"

2 The mother should be instructed that lotions and powders should not be applied to the incision site after cardiac surgery. Lotions and powders can irritate the surrounding skin, which could lead to skin breakdown and subsequent infection of the incision site. Options 1, 3, and 4 are accurate instructions regarding home care after cardiac surgery.

668. The nurse is preparing to give a bed bath to an immobilized client with tuberculosis. The nurse should wear which item when performing this care? 1. Surgical mask and gloves 2. Particulate respirator, gown, and gloves 3. Particulate respirator and protective eyewear 4. Surgical mask, gown, and protective eyewear

2 The nurse who is in contact with a client with tuberculosis should wear an individually fitted particulate respirator. The nurse also would wear gloves as per standard precautions. The nurse wears a gown when the possibility exists that the clothing could become contaminated, such as when giving a bed bath.

655. The emergency department nurse is assessing a client who has sustained a blunt injury to the chest wall. Which finding would indicate the presence of a pneumothorax in this client? 1. A low respiratory rate 2. Diminished breath sounds 3. The presence of a barrel chest 4. A sucking sound at the site of injury

2 This client has sustained a blunt or closed-chest injury. Basic symptoms of a closed pneumothorax are shortness of breath and chest pain. A larger pneumothorax may cause tachypnea, cyanosis, diminished breath sounds, and subcutaneous emphysema. Hyperresonance also may occur on the affected side. A sucking sound at the site of injury would be noted with an open chest injury.

718. A client with angina complains that the anginal pain is prolonged and severe and occurs at the same time each day, most often at rest in the absence of precipitating factors. How would the nurse best describe this type of anginal pain? 1. Stable angina 2. Variant angina 3. Unstable angina 4. Nonanginal pain

2 Variant angina, or Prinzmetal's angina, is prolonged and severe and occurs at the same time each day, most often at rest. Stable angina is induced by exercise and relieved by rest or nitroglycerin tablets. Unstable angina occurs at lower levels of activity or at rest, is less predictable, and is often a precursor of myocardial infarction.

725. A client with atrial fibrillation secondary to mitral stenosis is receiving a heparin sodium infusion at 1000 units/hour and warfarin sodium 7.5 mg at 5:00 PM daily. The morning laboratory results are as follows: activated partial thromboplastin time (aPTT) = 32 seconds; internationalized normalized ratio (INR) = 1.3. The nurse should plan to take which action based on the client's laboratory results? 1. Collaborate with the health care provider (HCP) to discontinue the heparin infusion and administer the warfarin sodium as prescribed. 2. Collaborate with the HCP to obtain a prescription to increase the heparin infusion and administer the warfarin sodium as prescribed. 3. Collaborate with the HCP to withhold the warfarin sodium since the client is receiving a heparin infusion and the aPTT is within the therapeutic range. 4. Collaborate with the HCP to continue the heparin infusion at the same rate and to discuss use of dabigatran etexilate (Pradaxa) in place of warfarin sodium.

2 When a client is receiving warfarin (Coumadin) for clot prevention due to atrial fibrillation, an INR of 2 to 3 is appropriate for most clients. Until the INR has achieved a therapeutic range the client should be maintained on a continuous heparin infusion with the aPTT ranging between 60 and 80 seconds. Therefore, the nurse should collaborate with the health care provider to obtain a prescription to increase the heparin infusion and to administer the warfarin as prescribed.

656. The nurse is caring for a client hospitalized with acute exacerbation of chronic obstructive pulmonary disease. Which finding would the nurse expect to note on assessment of this client? Select all that apply. 1. Hypocapnia 2. A hyperinflated chest noted on the chest x-ray 3. Decreased oxygen saturation with mild exercise 4. A widened diaphragm noted on the chest x-ray 5. Pulmonary function tests that demonstrate increased vital capacity

2, 3 Clinical manifestations of chronic obstructive pulmonary disease (COPD) include hypoxemia, hypercapnia, dyspnea on exertion and at rest, oxygen desaturation with exercise, and the use of accessory muscles of respiration. Chest x-rays reveal a hyperinflated chest and a flattened diaphragm if the disease is advanced. Pulmonary function tests will demonstrate decreased vital capacity.

729. The nurse is monitoring a client who is taking digoxin for adverse effects. Which findings are characteristic of digoxin toxicity? Select all that apply. 1. Tremors 2. Diarrhea 3. Irritability 4. Blurred vision 5. Nausea and vomiting

2, 4, 5 Digoxin (Lanoxin) is a cardiac glycoside. The risk of toxicity can occur with the use of this medication. Toxicity can lead to life-threatening events and the nurse needs to monitor the client closely for signs of toxicity. Early signs of toxicity include gastrointestinal manifestations such as anorexia, nausea, vomiting, and diarrhea. Subsequent manifestations include headache; visual disturbances such as diplopia, blurred vision, yellow-green halos, and photophobia; drowsiness; fatigue; and weakness. Cardiac rhythm abnormalities can also occur. The nurse also monitors the digoxin level. Therapeutic levels for digoxin range from 0.5 to 2 ng/mL.

443. Assessment findings of an infant admitted to the hospital reveal a machinery-like murmur on auscultation of the heart and signs of heart failure. The nurse reviews congenital cardiac anomalies and identifies the infant's condition as which disorder? Refer to figure on pg. 498 to determine the condition. 1. Aortic stenosis 2. Atrial septal defect 3. Patent ductus areteriosus 4. Ventricular septal defect

3 A patent ductus arteriosus is failure of the fetal ductus arteriosus (artery connecting the aorta and the pulmonary artery) to close. A characteristic machinery-like murmur is present, and the infant may show signs of heart failure. Aortic stenosis is a narrowing or stricture of the aortic valve. Arterial septal defect in an abnormal opening between the atria. Ventricular septal defect is an abnormal opening between the right and left ventricles.

661. The nurse is suctioning a client via an endotracheal tube. During the suctioning procedure, the nurse notes on the monitor that the heart rate is decreasing. Which nursing intervention is most appropriate? 1. Continue to suction. 2. Notify the health care provider immediately. 3. Stop the procedure and reoxygenate the client. 4. Ensure that the suction is limited to 15 seconds.

3 During suctioning, the nurse should monitor the client closely for side effects, including hypoxemia, cardiac irregularities such as a decrease in heart rate resulting from vagal stimulation, mucosal trauma, hypotension, and paroxysmal coughing. If adverse effects develop, especially cardiac irregularities, the procedure is stopped and the client is reoxygenated.

663. A client with a chest injury has suffered flail chest. The nurse assesses the client for which most distinctive sign of flail chest? 1. Cyanosis 2. Hypotension 3. Paradoxical chest movement 4. Dyspnea, especially on exhalation

3 Flail chest results from multiple rib fractures. This results in a "floating" section of ribs. Because this section is unattached to the rest of the bony rib cage, this segment results in paradoxical chest movement. This means that the force of inspiration pulls the fractured segment inward, while the rest of the chest expands. Similarly, during exhalation, the segment balloons outward while the rest of the chest moves inward. This is a characteristic sign of flail chest.

679. A client has a prescription to take guaifenesin. The nurse determines that the client understands the proper administration of this medication if the client states that he or she will perform which action? 1. Take an extra dose if fever develops 2. Take the medication with meals only 3. Take the tablet with a full glass of water 4. Decrease the amount of daily fluid intake

3 Guaifenesin (Mucinex) is an expectorant and should be taken with a full glass of water to decrease the viscosity of secretions. Extra doses should not be taken. The client should contact the health care provider if the cough lasts longer than 1 week or is accompanied by fever, rash, sore throat, or persistent headache. Fluids are needed to decrease the viscosity of secretions. The medication does not have to be taken with meals.

434. The nurse is monitoring an infant with congential heart disease closely for signs of heart failure. The nurse should assess the infant for which early signs of HF? 1. Pallor 2. Cough 3. Tachycardia 4. Slow and shallow breathing

3 HF is the inability of the heart to pump a sufficient amount of blood to meet the oxygen and metabolic needs of the body. The early signs of HF include tachycardia, tachypnea, profuse scalp sweating, fatigue and irritability, sudden weight gain, and respiratory distress. A cough may occur in HF as a result of mucosal swelling and irritation, but is not an early sign. Pallor may be noted in an infant with HF, but is not an early sign.

660. The nurse is preparing to suction a client via a tracheostomy tube. The nurse should plan to limit the suctioning time to a maximum of which time period? 1. 1 minute 2. 5 seconds 3. 10 seconds 4. 30 seconds

3 Hypoxemia can be caused by prolonged suctioning, which stimulates the pacemaker cells in the heart. A vasovagal response may occur, causing bradycardia. The nurse must preoxygenate the client before suctioning and limit the suctioning pass to 10 seconds.

659. The nurse is caring for a client after a bronchoscopy and biopsy. Which finding, if noted in the client, should be reported immediately to the health care provider? 1. Dry cough 2. Hematuria 3. Bronchospasm 4. Blood-streaked sputum

3 If a biopsy was performed during a bronchoscopy, blood-streaked sputum is expected for several hours. Frank blood indicates hemorrhage. A dry cough may be expected. The client should be assessed for signs/symptoms of complications, which would include cyanosis, dyspnea, stridor, bronchospasm, hemoptysis, hypotension, tachycardia, and dysrhythmias. Hematuria is unrelated to this procedure.

678. The low-pressure alarm sounds on a ventilator. The nurse assesses the client and then attempts to determine the cause of the alarm. If unsuccessful in determining the cause of the alarm, the nurse should take what initial action? 1. Administer oxygen 2. Check the client's vital signs 3. Ventilate the client manually 4. Start cardiopulmonary resuscitation

3 If at any time an alarm is sounding and the nurse cannot quickly ascertain the problem, the client is disconnected from the ventilator and manual resuscitation is used to support respirations until the problem can be corrected. No reason is given to begin cardiopulmonary resuscitation. Checking vital signs is not the initial action. Although oxygen is helpful, it will not provide ventilation to the client.

689. A client with tuberculosis is being started on antituberculosis therapy with isoniazid. Before giving the client the first dose, the nurse should ensure that which baseline study has been completed? 1. Electrolyte levels 2. Coagulation times 3. Liver enzyme levels 4. Serum creatinine level

3 Isoniazid therapy can cause an elevation of hepatic enzyme levels and hepatitis. Therefore, liver enzyme levels are monitored when therapy is initiated and during the first 3 months of therapy. They may be monitored longer in the client who is older than 50 or abuses alcohol. The laboratory tests in options 1, 2, and 4 are not necessary.

431. The mother of a hospitalized 2 y/o child with viral laryngotracheobronchitis (coup) asks the nurse why the HCP did not prescribe antibiotics. Which response should the nurse make? 1. "The child may be allergic to antibiotics" 2. "The child is too young to receive antibiotics" 3. "Antibiotics are not indicated unless a bacterial infection is present" 4. "The child still has the maternal antibodies from birth and does not need antibiotics"

3 Laryngotracheobronchitis (croup) is the inflammation of the larynx, trachea, and bronchi and is the most common type of croup. It can be viral or bacterial. Antibiotics are not indicated in the treatment of croup unless a bacterial infection is present. Options 1, 2, and 4 are incorrect. In addition, no supporting data in the question indicate that the child may be allergic to antibiotics.

702. The nurse is reviewing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.16 second, and QRS complexes measure 0.06 second. The overall heart rate is 64 beats/minute. Which would be a correct interpretation based on these characteristics? 1. Sinus bradycardia 2. Sick sinus syndrome 3. Normal sinus rhythm 4. First-degree heart block

3 Normal sinus rhythm is defined as a regular rhythm, with an overall rate of 60 to 100 beats/minute. The PR and QRS measurements are normal, measuring 0.12 to 0.20 second and 0.04 to 0.10 second, respectively.

687. A client has been started on long-term therapy with rifampin. The nurse should provide which information to the client about the medication? 1. Should always be taken with food or antacids 2. Should be double-dosed if one dose is forgotten 3. Causes orange discoloration of sweat, tears, urine, and feces 4. May be discontinued independently if symptoms are gone in 3 months

3 Rifampin (Rifadin) should be taken exactly as directed. Doses should not be doubled or skipped. The client should not stop therapy until directed to do so by a health care provider. The medication should be administered on an empty stomach unless it causes gastrointestinal upset, and then it may be taken with food. Antacids, if prescribed, should be taken at least 1 hour before the medication. Rifampin causes orange-red discoloration of body secretions and will stain soft contact lenses permanently.

703. A client is wearing a continuous cardiac monitor, which begins to sound its alarm. A nurse sees no electrocardiographic complexes on the screen. Which is the priority action of the nurse? 1. Call a code. 2. Call the health care provider. 3. Check the client's status and lead placement. 4. Press the recorder button on the electrocardiogram console.

3 Sudden loss of electrocardiographic complexes indicates ventricular asystole or possibly electrode displacement. Accurate assessment of the client and equipment is necessary to determine the cause and identify the appropriate intervention. The remaining options are secondary to client assessment.

683. Terbutaline is prescribed for a client with bronchitis. The nurse understands that this medication should be used with caution if which medical condition is present in the client? 1. Osteoarthritis 2. Hypothyroidism 3. Diabetes mellitus 4. Polycystic disease

3 Terbutaline is a bronchodilator and is contraindicated in clients with hypersensitivity to sympathomimetics. It should be used with caution in clients with impaired cardiac function, diabetes mellitus, hypertension, hyperthyroidism, or a history of seizures. The medication may increase blood glucose levels.

733. A client receiving thrombolytic therapy with a continuous infusion of alteplase suddenly becomes extremely anxious and complains of itching. The nurse hears stridor and notes generalized urticaria and hypotension. Which nursing action is the priority? 1. Administer oxygen and protamine sulfate. 2. Cut the infusion rate in half and sit the client up in bed. 3. Stop the infusion and call the health care provider (HCP). 4. Administer diphenhydramine (Benadryl) and continue the infusion.

3 The client is experiencing an anaphylactic reaction. Therefore, the priority action is to stop the infusion and notify the HCP. The client may be treated with epinephrine, antihistamines, and corticosteroids as prescribed.

707. A client has developed atrial fibrillation, with a ventricular rate of 150 beats/minute. The nurse should assess the client for which associated signs/symptoms? 1. Flat neck veins 2. Nausea and vomiting 3. Hypotension and dizziness 4. Hypertension and headache

3 The client with uncontrolled atrial fibrillation with a ventricular rate more than 100 beats/minute is at risk for low cardiac output because of loss of atrial kick. The nurse assesses the client for palpitations, chest pain or discomfort, hypotension, pulse deficit, fatigue, weakness, dizziness, syncope, shortness of breath, and distended neck veins.

669. A client has experienced pulmonary embolism. The nurse should assess for which symptom, which is most commonly reported? 1. Hot, flushed feeling 2. Sudden chills and fever 3. Chest pain that occurs suddenly 4. Dyspnea when deep breaths are taken

3 The most common initial symptom in pulmonary embolism is chest pain that is sudden in onset. The next most commonly reported symptom is dyspnea, which is accompanied by an increased respiratory rate. Other typical symptoms of pulmonary embolism include apprehension and restlessness, tachycardia, cough, and cyanosis.

680. The nurse is preparing to administer a dose of naloxone hydrochloride intravenously to a client with an intravenous opioid overdose. Which supportive medical equipment should the nurse plan to have at the client's bedside if needed? 1. Nasogastric tube 2. Paracentesis tray 3. Resuscitation equipment 4. Central line insertion tray

3 The nurse administering naloxone for suspected opioid overdose should have resuscitation equipment readily available to support naloxone therapy if it is needed. Other adjuncts that may be needed include oxygen, mechanical ventilator, and vasopressors.

727. The nurse is planning to administer hydrochlorothiazide to a client. The nurse understands that which is a concern related to the administration of this medication? 1. Hypouricemia, hyperkalemia 2. Increased risk of osteoporosis 3. Hypokalemia, hyperglycemia, sulfa allergy 4. Hyperkalemia, hypoglycemia, penicillin allergy

3 Thiazide diuretics such as hydrochlorothiazide are sulfa-based medications, and a client with a sulfa allergy is at risk for an allergic reaction. Also, clients are at risk for hypokalemia, hyperglycemia, hypercalcemia, hyperlipidemia, and hyperuricemia.

734. The nurse should report which assessment finding to the health care provider (HCP) before initiating thrombolytic therapy in a client with pulmonary embolism? 1. Adventitious breath sounds 2. Temperature of 99.4 ° F orally 3. Blood pressure of 198/110 mm Hg 4. Respiratory rate of 28 breaths/minute

3 Thrombolytic therapy is contraindicated in a number of preexisting conditions in which there is a risk of uncontrolled bleeding, similar to the case in anticoagulant therapy. Thrombolytic therapy also is contraindicated in severe uncontrolled hypertension because of the risk of cerebral hemorrhage. Therefore the nurse would report the results of the blood pressure to the HCP before initiating therapy.

726. A client is diagnosed with an ST-segment elevation myocardial infarction (STEMI) and is receiving tissue plasminogen activator, alteplase. Which action is a priority nursing intervention? 1. Monitor for kidney failure. 2. Monitor psychosocial status. 3. Monitor for signs of bleeding. 4. Have heparin sodium available.

3 Tissue plasminogen activator is a thrombolytic. Hemorrhage is a complication of any type of thrombolytic medication. The client is monitored for bleeding. Monitoring for renal failure and monitoring the client's psychosocial status are important but are not the most critical interventions. Heparin may be administered after thrombolytic therapy, but the question is not asking about follow-up medications.

677. The nurse performs an admission assessment on a client with a diagnosis of tuberculosis. The nurse should check the results of which diagnostic test that will confirm this diagnosis? 1. Chest x-ray 2. Bronchoscopy 3. Sputum culture 4. Tuberculin skin test

3 Tuberculosis is definitively diagnosed through culture and isolation of Mycobacterium tuberculosis. A presumptive diagnosis is made based on a tuberculin skin test, a sputum smear that is positive for acid-fast bacteria, a chest x-ray, and histological evidence of granulomatous disease on biopsy.

719. The nurse notes that a client with sinus rhythm has a premature ventricular contraction that falls on the T wave of the preceding beat. The client's rhythm suddenly changes to one with no P waves, no definable QRS complexes, and coarse wavy lines of varying amplitude. How should the nurse correctly interpret this rhythm? 1. Asystole 2. Atrial fibrillation 3. Ventricular fibrillation 4. Ventricular tachycardia

3 Ventricular fibrillation is characterized by irregular chaotic undulations of varying amplitudes. Ventricular fibrillation has no measurable rate and no visible P waves or QRS complexes and results from electrical chaos in the ventricles.

704. The nurse is watching the cardiac monitor and notices that the rhythm suddenly changes. There are no P waves, the QRS complexes are wide, and the ventricular rate is regular but more than 140 beats/minute. The nurse determines that the client is experiencing which dysrhythmia? 1. Sinus tachycardia 2. Ventricular fibrillation 3. Ventricular tachycardia 4. Premature ventricular contractions

3 Ventricular tachycardia is characterized by the absence of P waves, wide QRS complexes (longer than 0.12 second), and typically a rate between 140 and 180 impulses/minute. The rhythm is regular.

684. Zafirlukast is prescribed for a client with bronchial asthma. Which laboratory test does the nurse expect to be prescribed before the administration of this medication? 1. Platelet count 2. Neutrophil count 3. Liver function tests 4. Complete blood count

3 Zafirlukast (Accolate) is a leukotriene receptor antagonist used in the prophylaxis and long-term treatment of bronchial asthma. Zafirlukast is used with caution in clients with impaired hepatic function. Liver function laboratory tests should be performed to obtain a baseline, and the levels should be monitored during administration of the medication.

439. The clinic nurse reviews the record of a child just seen by a health care provider and diagnosed with suspected aortic stenosis. The nurse expects to note documentation of which clinical manifestation specifically found in this disorder? 1. Pallor 2. Hyperactivity 3. Exercise intolerance 4. Gastrointestinal disturbances

3 Aortic stenosis is a narrowing or stricture of the aortic valve, causing resistance to blood flow in the left ventricle, decreased cardiac output, left ventricular hypertrophy, and pulmonary vascular congestion. A child with aortic stenosis shows signs of exercise intolerance, chest pain, and dizziness when standing for long periods. Pallor may be noted but it is not specific to this type of disorder alone. Options 2 and 4 are not related to this disorder.

436. On assessment of a child admitted with a diagnosis of acute stage Kawasaki disease, the nurse expects to note which clinical manifestation of the acute stage of the disease? 1. Cracked lips 2. Normal appearance 3. Conjunctional hyperemia 4. Desquamation of the skin

3 Kawasaki disease, also known as mucocutaneous lymph node syndrome, is an acute systemic inflammatory illness. In the acute stage, the child has a fever, conjunctival hyperemia, red throat, swollen hands, rash, and enlargement of the cervical lymph nodes. In the subacute stage, cracking lips and tissues, desquamation of the skin on the tips of the fingers and toes, joint pain, cardiac manifestations, and thrombocytosis occur. In the convalescent stage, the child appears normal, but signs of inflammation may be present.

730. Prior to administering a client's daily dose of digoxin, the nurse reviews the client's laboratory data and notes the following results: serum calcium, 9.8 mg/dL; serum magnesium, 1.2 mg/dL; serum potassium, 4.1 mEq/L; serum creatinine, 0.9 mg/dL. Which result should alert the nurse that the client is at risk for digoxin toxicity? 1. Serum calcium level 2. Serum potassium level 3. Serum creatinine level 4. Serum magnesium level

4 An increased risk of toxicity exists in clients with hypercalcemia, hypokalemia, hypomagnesemia, hypothyroidism, and impaired renal function. The calcium, creatinine, and potassium levels are all within normal limits. The normal range for magnesium is 1.6 to 2.6 mg/dL and the results in the correct option are reflective of hypomagnesemia.

731. A client being treated for heart failure is administered intravenous bumetanide. Which outcome indicates the medication has achieved the expected effect? 1. Cough becomes productive of frothy pink sputum 2. The serum potassium level changes from 3.8 to 3.1 mEq/L 3. B-natriuretic peptide (BNP) factor increases from 200 to 262 pg/mL 4. Urine output increases from 10 mL/hour to greater than 50 mL hourly

4 Bumetanide is a diuretic and expected outcomes include increased urine output, decreased crackles, and decreased weight. Options 1, 2, and 3 are incorrect.

682. A cromolyn sodium inhaler is prescribed for a client with allergic asthma. The nurse provides instructions regarding the side and adverse effects of this medication and should tell the client that which undesirable effect is associated with this medication? 1. Insomnia 2. Constipation 3. Hypotension 4. Bronchospasm

4 Cromolyn sodium is an inhaled nonsteroidal antiallergy agent and a mast cell stabilizer. Undesirable effects associated with inhalation therapy of cromolyn sodium are bronchospasm, cough, nasal congestion, throat irritation, and wheezing. Clients receiving this medication orally may experience pruritus, nausea, diarrhea, and myalgia.

427. The clinic nurse is providing instructions to a parent of a child with cystic fibrosis regarding the immunization schedule for the child. Which statement should the nurse make to the parent? 1. "The immunization schedule will need to be altered" 2. "The child should not receive any hepatitis vaccines" 3. "The child will receive all the immunizations except for the polio series" 4. "The child will receive the recommended basic series of immunizations along with a yearly influenza vaccination"

4 Cystic fibrosis is a chronic multisystem disorder (autosomal recessive trait disorder) characterized by exocrine gland dysfunction. The mucus produced by the exocrine glands is abnormally thick, tenacious, and copious, causing obstruction of the small passageways of the affected organs, particularly in the respiratory, GI, and reproductive systems. Adequately protecting children with CF from communicable disease by immunization is essential. In addition to the basic series of immunizations, a yearly influenza immunization is recommended for children with CF. Options 1, 2, and 3 are incorrect.

437. The nurse provides home care instructions to the parents of a child with heart failure regarding the procedure for administration of digoxin. Which statement made by the parent indicates the need for further instruction? 1. "I will not mix the medication with food" 2. "I will take my child's pulse before administrating the medication" 3. "If more than one dose is missed, I will call the HCP" 4. "If my child vomits after medication administration, I will repeat the dose"

4 Digoxin is a cardiac glycoside. The parents need to be instructed that if the child vomits after digoxin is administered, they are not to repeat the dose. Options 1, 2, and 3 are accurate instructions regarding the administration of this medication. In addition, the parents should be instructed that if a dose is missed and is not identified until 4 hours later, the dose should not be administered.

672. The nurse is giving discharge instructions to a client with pulmonary sarcoidosis. The nurse concludes that the client understands the information if the client indicates to report which early sign of exacerbation? 1. Fever 2. Fatigue 3. Weight loss 4. Shortness of breath

4 Dry cough and dyspnea are typical early manifestations of pulmonary sarcoidosis. Later manifestations include night sweats, fever, weight loss, and skin nodules.

721. The nurse provides discharge instructions to a client who is taking warfarin sodium. Which statement, by the client, reflects the need for further teaching? 1. "I will avoid alcohol consumption." 2. "I will take my pills every day at the same time." 3. "I have already called my family to pick up a Medic-Alert bracelet." 4. "I will take enteric-coated aspirin for my headaches because it is coated."

4 Ecotrin is an aspirin-containing product and should be avoided. Alcohol consumption should be avoided by a client taking warfarin sodium. Taking prescribed medication at the same time each day increases client compliance. The Medic-Alert bracelet provides health care personnel emergency information.

688. The nurse has given a client taking ethambutol information about the medication. The nurse determines that the client understands the instructions if the client states he or she will immediately report which finding? 1. Impaired sense of hearing 2. Gastrointestinal side effects 3. Orange-red discoloration of body secretions 4. Difficulty in discriminating the color red from green

4 Ethambutol (Myambutol) causes optic neuritis, which decreases visual acuity and the ability to discriminate between the colors red and green. This poses a potential safety hazard when a client is driving a motor vehicle. The client is taught to report this symptom immediately. The client also is taught to take the medication with food if gastrointestinal upset occurs. Impaired hearing results from antitubercular therapy with streptomycin. Orange-red discoloration of secretions occurs with rifampin (Rifadin).

716. The nurse is evaluating the condition of a client after pericardiocentesis performed to treat cardiac tamponade. Which observation would indicate that the procedure was unsuccessful? 1. Rising blood pressure 2. Clearly audible heart sounds 3. Client expressions of relief 4. Rising central venous pressure

4 Following pericardiocentesis, a rise in blood pressure and a fall in central venous pressure are expected. The client usually expresses immediate relief. Heart sounds are no longer muffled or distant.

697. A client in sinus bradycardia, with a heart rate of 45 beats/minute, complains of dizziness and has a blood pressure of 82/60 mm Hg. Which prescription should the nurse anticipate will be prescribed? 1. Defibrillate the client. 2. Administer digoxin (Lanoxin). 3. Continue to monitor the client. 4. Prepare for transcutaneous pacing.

4 Hypotension and dizziness are signs of decreased cardiac output. Transcutaneous pacing provides a temporary measure to increase the heart rate and thus perfusion in the symptomatic client. Defibrillation is used for treatment of pulseless ventricular tachycardia and ventricular fibrillation. Digoxin will further decrease the client's heart rate. Continuing to monitor the client delays necessary intervention.

429. A child with laryngotracheobronchitis (croup) is placed in a cool mist tent. The mother becomes concerned because the child is frightened, consistently crying and trying to climb out of the tent. Which is the most appropriate nursing action? 1. Tell the mother that the child must stay in the tent 2. Place a toy in the tent to make the child feel more comfortable 3. Call the HCP and obtain a prescription for a mild sedative 4. Let the mother hold the child and direct the cool mist over the child's face

4 Laryngotracheobronchitis (croup) is the inflammation of the larynx, trachea, and bronchi and is the most common type of croup. Cool mist therapy may be prescribed to liquefy secretions and to assist in breathing. If the use of tent or hood is causing distress, treatment may be more effective if the child is held by the parent and a cool mist is directed toward the child's face (blow-by). A mild sedative would not be administered to the child. Crying would increase hypoxia and aggravate laryngospasms, which may cause airway obstruction. Options 1 and 2 would not alleviate the child's fear.

696. A client admitted to the hospital with chest pain and a history of type 2 diabetes mellitus is scheduled for cardiac catheterization. Which medication would need to be withheld for 24 hours before the procedure and for 48 hours after the procedure? 1. Regular insulin 2. Glipizide (Glucotrol) 3. Repaglinide (Prandin) 4. Metformin (Glucophage)

4 Metformin (Glucophage) needs to be withheld 24 hours before and for 48 hours after cardiac catheterization because of the injection of contrast medium during the procedure. If the contrast medium affects kidney function, with metformin in the system, the client would be at increased risk for lactic acidosis. The medications in the remaining options do not need to be withheld 24 hours before and 48 hours after cardiac catheterization.

728. The home health care nurse is visiting a client with elevated triglyceride levels and a serum cholesterol level of 398 mg/dL. The client is taking cholestyramine (Questran). Which statement, by the client, indicates the need for further education? 1. "Constipation and bloating might be a problem." 2. "I'll continue to watch my diet and reduce my fats." 3. "Walking a mile each day will help the whole process." 4. "I'll continue my nicotinic acid from the health food store."

4 Nicotinic acid, even an over-the-counter form, should be avoided because it may lead to liver abnormalities. All lipid lowering medications also can cause liver abnormalities, so a combination of nicotinic acid and cholestyramine resin needs to be avoided. Constipation and bloating are the two most common side effects. Walking and the reduction of fats in the diet are therapeutic measures to reduce cholesterol and triglyceride levels.

693. The nurse has just administered the first dose of omalizumab to a client. Which statement by the client would alert the nurse that the client may be experiencing a lifethreatening effect? 1. "I have a severe headache." 2. "My feet are quite swollen." 3. "I am nauseated and may vomit." 4. "My lips and tongue are swollen."

4 Omalizumab (Xolair) is an antiinflammatory used for long-term control of asthma. Anaphylactic reactions can occur with the administration of omalizumab. The nurse administering the medication should monitor for adverse reactions of the medication. Swelling of the lips and tongue are an indication of an adverse reaction. The client statements in options 1, 2, and 3 are not indicative of an adverse reaction.

676. The community health nurse is conducting an educational session with community members regarding the symptoms associated with tuberculosis. Which is one of the first manifestations associated with tuberculosis? 1. Dyspnea 2. Chest pain 3. A bloody, productive cough 4. A cough with the expectoration of mucoid sputum

4 One of the first pulmonary manifestations of tuberculosis is a slight cough with the expectoration of mucoid sputum. Options 1, 2, and 3 are late manifestations and signify cavitation and extensive lung involvement.

425. The mother of an 8 y/o child being treated for right lower lobe pneumonia at home calls the clinic nurse. The mother tells the nurse that the child complains of discomfort on the right side and that ibuprofen is not effective. Which instruction should the nurse provide to the mother? 1. Increase the dose of ibuprofen 2. Increase the frequency of ibuprofen 3. Encourage the child to lie on the left side 4. Encourage the child to lie on the right side

4 Pneumonia is an inflammation of the pulmonary parenchyma or alveoli or both caused by a virus mycoplasmal agents, bacteria, or aspiration of foreign substances. Splinting of the affected side by lying on that side may decrease discomfort. It would be inappropriate to advise the mother to increase the dose or frequency of the ibuprofen. Lying on the left side would not be helpful in alleviating discomfort.

675. The nurse is instructing a hospitalized client with a diagnosis of emphysema about measures that will enhance the effectiveness of breathing during dyspneic periods. Which position should the nurse instruct the client to assume? 1. Sitting up in bed 2. Side-lying in bed 3. Sitting in a recliner chair 4. Sitting on the side of the bed and leaning on an overbed table

4 Positions that will assist the client with emphysema with breathing include sitting up and leaning on an overbed table, sitting up and resting the elbows on the knees, and standing and leaning against the wall.

706. A client is having frequent premature ventricular contractions. The nurse should place priority on assessment of which item? 1. Sensation of palpitations 2. Causative factors, such as caffeine 3. Precipitating factors, such as infection 4. Blood pressure and oxygen saturation

4 Premature ventricular contractions can cause hemodynamic compromise. Therefore, the priority is to monitor the blood pressure and oxygen saturation. The shortened ventricular filling time can lead to decreased cardiac output. The client may be asymptomatic or may feel palpitations. Premature ventricular contractions can be caused by cardiac disorders, states of hypoxemia, or by any number of physiological stressors, such as infection, illness, surgery, or trauma, and by intake of caffeine, nicotine, or alcohol.

657. The nurse instructs a client to use the pursed-lip method of breathing and the client asks the nurse about the purpose of this type of breathing. The nurse responds, knowing that the primary purpose of pursed-lip breathing is to promote which outcome? 1. Promote oxygen intake 2. Strengthen the diaphragm 3. Strengthen the intercostal muscles 4. Promote carbon dioxide elimination

4 Pursed-lip breathing facilitates maximal expiration for clients with obstructive lung disease. This type of breathing allows better expiration by increasing airway pressure that keeps air passages open during exhalation. Options 1, 2, and 3 are not the purposes of this type of breathing.

435. The nurse reviews the laboratory results for a child with a suspected diagnosis of rheumatic fever, knowing that which laboratory study would assist in confirming the diagnosis? 1. Immunoglobulin 2. Red blood cell count 3. White blood cell count 4. Anti-streptolysin O titer

4 Rheumatic fever is an inflammatory autoimmune disease that affects the connective tissues of the heart, joints, skin (SQ tissues), blood vessels, and central nervous system. A diagnosis of rheumatic fever is confirmed by the presence of two major manifestations from the Jones criteria. In addition, evidence of a recent streptococcal infection is confirmed by a positive anti-streptolysin O titer, streptozyme assay, or anti-DNase B assay. Options 1, 2, and 3 would not help to confirm the diagnosis of rheumatic fever.

441. A child with rheumatic fever will be arriving in the nursing unit for admission. On admission assessment, the nurse should ask the parents which question to elicit assessment information specific to the development of rheumatic fever? 1. "Has the child complained of back pain?" 2. "Has the child complained of headaches?" 3. "Has the child had any nausea or vomiting?" 4. "Did the child have a sore throat or fever within the last 2 months?"

4 Rheumatic fever is an inflammatory autoimmune disease that affects the connective tissues of the heart, joints, skin (SQ tissues), blood vessels, and central nervous system. Rheumatic fever characteristically manifests 2-6 weeks after an untreated or partially treated group A beta-hemolytic streptococcal infection of the upper respiratory tract. Initially, the nurse determines whether the child had a sore throat or an unexplained fever within the past 2 months. Options 1, 2, and 3 are unrelated to rheumatic fever.

662. The nurse is assessing the respiratory status of a client who has suffered a fractured rib. The nurse should expect to note which finding? 1. Slow deep respirations 2. Rapid deep respirations 3. Paradoxical respirations 4. Pain, especially with inspiration

4 Rib fractures are a common injury, especially in the older client, and result from a blunt injury or a fall. Typical signs and symptoms include pain and tenderness localized at the fracture site that is exacerbated by inspiration and palpation, shallow respirations, splinting or guarding the chest protectively to minimize chest movement, and possible bruising at the fracture site. Paradoxical respirations are seen with flail chest.

426. A new parent expresses concern to the nurse regarding sudden infant death syndrome. She asks the nurse how to position her new infant for sleep. In which position should the nurse tell the parent to place the infant? 1. Side or prone 2. Back or prone 3. Stomach with the face turned 4. Back rather than on the stomach

4 SIDS is the unexpected death of an apparently healthy infant younger than 1 year for whom an investigation of the death and a thorough autopsy fail to show an adequate cause of death. Several theories are proposed regarding the cause, but the exact cause is unknown. Nurses should encourage parents to place the infant on the back (supine) for sleep. Infants in the prone position (on the stomach) may be unable to move their heads to the side, increasing the risk of suffocation. The infant may have the ability to turn to a prone from the side-lying position.

723. A client is being treated with procainamide for a cardiac dysrhythmia. Following intravenous administration of the medication, the client complains of dizziness. What intervention should the nurse take first? 1. Measure the heart rate on the rhythm strip. 2. Administer prescribed nitroglycerin tablets. 3. Obtain a 12-lead electrocardiogram immediately. 4. Auscultate the client's apical pulse and obtain a blood pressure.

4 Signs of toxicity from procainamide include confusion, dizziness, drowsiness, decreased urination, nausea, vomiting, and tachydysrhythmias. If the client complains of dizziness, the nurse should assess the vital signs first. Although measuring the heart rate on the rhythm strip and obtaining a 12-lead EKG may be interventions, these would be done after the vital signs are taken. Nitroglycerin is a vasodilator and will lower the blood pressure.

667. The nurse has conducted discharge teaching with a client diagnosed with tuberculosis, who has been receiving medication for 11⁄2 weeks. The nurse determines that the client has understood the information if the client makes which statement? 1. "I need to continue drug therapy for 2 months." 2. "I can't shop at the mall for the next 6 months." 3. "I can return to work if a sputum culture comes back negative." 4. "I should not be contagious after 2 to 3 weeks of medication therapy."

4 The client is continued on medication therapy for 6 to 12 months, depending on the situation. The client generally is considered noncontagious after 2 to 3 weeks of medication therapy. The client is instructed to wear a mask if there will be exposure to crowds until the medication is effective in preventing transmission. The client is allowed to return to work when the results of three sputum cultures are negative.

665. The nurse is assessing a client with multiple trauma who is at risk for developing acute respiratory distress syndrome. The nurse should assess for which earliest sign of acute respiratory distress syndrome? 1. Bilateral wheezing 2. Inspiratory crackles 3. Intercostal retractions 4. Increased respiratory rate

4 The earliest detectable sign of acute respiratory distress syndrome is an increased respiratory rate, which can begin from 1 to 96 hours after the initial insult to the body. This is followed by increasing dyspnea, air hunger, retraction of accessory muscles, and cyanosis. Breath sounds may be clear or consist of fine inspiratory crackles or diffuse coarse crackles.

710. A client in ventricular fibrillation is about to be defibrillated. A nurse knows that to convert this rhythm effectively, the monophasic defibrillator machine should be set at which energy level (in joules, J) for the first delivery? 1. 50 J 2. 120 J 3. 200 J 4. 360 J

4 The energy level used for all defibrillation attempts with a monophasic defibrillator is 360 joules.

713. The nurse is caring for a client who has just had implantation of an automatic internal cardioverter-defibrillator. The nurse immediately would assess which item based on priority? 1. Anxiety level of the client and family 2. Presence of a Medic-Alert card for the client to carry 3. Knowledge of restrictions of postdischarge physical activity 4. Activation status of the device, heart rate cutoff, and number of shocks it is programmed to deliver

4 The nurse who is caring for the client after insertion of an automatic internal cardioverter-defibrillator needs to assess device settings, similar to after insertion of a permanent pacemaker. Specifically, the nurse needs to know whether the device is activated, the heart rate cutoff above which it will fire, and the number of shocks it is programmed to deliver. The remaining options are also nursing interventions but are not the priority.

709. The nurse is assisting to defibrillate a client in ventricular fibrillation. After placing the paddles on the client's chest and before discharging them, which intervention should be done? 1. Ensure that the client has been intubated. 2. Set the defibrillator to the "synchronize" mode. 3. Administer an amiodarone bolus intravenously. 4. Confirm that the rhythm is actually ventricular fibrillation.

4 Until the defibrillator is attached and charged, the client is resuscitated by using cardiopulmonary resuscitation. Once the defibrillator has been attached, the electrocardiogram is checked to verify that the rhythm is ventricular fibrillation or pulseless ventricular tachycardia. Leads also are checked for any loose connections. A nitroglycerin patch, if present, is removed. The client does not have to be intubated to be defibrillated. The machine is not set to the synchronous mode because there is no underlying rhythm with which to synchronize. Amiodarone may be given subsequently but is not required before defibrillation.

442. A HCP has prescribed oxygen as needed for an infant with heart failure. In which situation should the nurse administer the oxygen to the infant? 1. During sleep 2. When changing the infant's diapers 3. When the mother is holding the infant 4. When drawing blood for electrolyte level testing

4 HF is the inability of the heart to pump a sufficient amount of blood to meet the oxygen and metabolic needs of the body. Crying exhausts the limited energy supply, increases the workload of the heart, and increases the oxygen demands. Oxygen administration may be prescribed for stressful periods, especially during bouts of crying or invasive procedures. Options 1, 2, and 3 are not likely to produce crying in the infant.
