Pharmacology
A patient is receiving warfarin [Coumadin] for a chronic condition. Which patient statement requires immediate action by the nurse?
"I will increase dark green, leafy vegetables in my diet." Dark green, leafy vegetables are rich in vitamin K, which would antagonize the effects of warfarin. Rather than increase the intake of these vegetables, it is more important to maintain a consistent daily intake of vitamin K. The patient should monitor his or her incidence of bruising carefully. The medication will usually be ordered to be taken at the same time each day.
Which statement made by a patient about nitroglycerin indicates understanding?
"I will keep the nitroglycerin stored in the bottle it comes in." Nitroglycerin needs to be stored away from heat, humidity, and light, all of which can decrease its potency. Keeping it in the brown light-resistant bottle helps achieve this. It should be replaced every 3 to 6 months to maintain potency. Nitroglycerin is used every 5 minutes for pain relief or just prior to engaging in activity that is known to cause chest pain.
The nurse is teaching a patient who is being discharged with a prescription for metoprolol. Which patient statement indicates understanding of the teaching?
"I will not drive until I know how this medication affects me." Metoprolol can cause dizziness and blood pressure changes. Patients should not drive until they know how the body will respond to the medication.
Which statement indicates that the patient needs additional teaching on oral hypoglycemic agents?
"I will take the medication only when I need it." Oral hypoglycemic agents must be taken on a daily scheduled basis to maintain euglycemia and prevent long-term complications of diabetes. When alcohol is ingested with certain oral hypoglycemic drugs, the hypoglycemic effect can be intensified. The patient may experience fatigue and loss of appetite as side effects of the medication, and these should be reported to the healthcare provider. The patient needs to closely monitor blood sugar.

A patient who is prescribed lisinopril asks the nurse, "Will this drug help the swelling in my legs?" Which nursing response is appropriate?
"Lisinopril may help the edema from progressing, as this drug suppresses aldosterone, which promotes sodium and water excretion."
A patient who is prescribed lisinopril asks the nurse, "Will this drug help the swelling in my legs?" Which nursing response is appropriate?
"Lisinopril may help the edema from progressing, as this drug suppresses aldosterone, which promotes sodium and water excretion." Lisinopril does suppress the release of aldosterone, which promotes sodium and water excretion. With an increase in sodium and water excretion, the edema should not progress, however, a diuretic may still be required in conjunction with the angiotensin-converting enzyme (ACE) inhibitor.
The nurse is teaching a patient about the transmission of malarial infections. Which statement made by the nurse is appropriate?
"Malaria is transmitted by an infected female mosquito."
A patient is newly diagnosed with hypertension and asks for a minoxidil prescription. The patient states, "It was the only medication that helped my dad's hypertension." Which nursing statement is appropriate?

A 30-year-old female patient who is taking a beta blocker asks the nurse, "Can I take this drug if I am considering pregnancy?" Which nursing response is appropriate?
"There is potential risk to the fetus because metoprolol crosses the placental barrier." Beta blockers readily cross the placental barrier, which has known risks to the fetus.
What is the best information for the nurse to provide to a patient who is receiving spironolactone and furosemide therapy?
"This combination promotes urine output but decreases the risk of low potassium." Spironolactone [Aldactone] is a potassium-sparing diuretic; furosemide [Lasix] causes potassium loss. Giving these together minimizes electrolyte imbalance. It is not accurate to state that the drug combination prevents dehydration and loss of fluid volume or that it increases the osmolality of plasma and the glomerular filtration rate. Stating that giving two different diuretics is more effective than a large dose of one is not accurate.

"This medication is very expensive, but you will be receiving it only a short time." "This medication has a duration of action of 24 hours."
"This medication has a duration of action of 24 hours." Insulin glargine (Lantus) has a duration of action of 24 hours with no peaks, mimicking the natural, basal insulin secretion of the pancreas. This medication cannot be mixed with other insulins and is not a short-acting insulin. The patient may need to receive this medication for a long time.
What information will the nurse teach the patient who has been prescribed an alpha glucosidase inhibitor? This medication will stimulate pancreatic insulin release." "This medication will increase the sensitivity of insulin receptor sites." "This medication will delay the absorption of carbohydrates from the intestines." "This medication cannot be used in combination with other antidiabetic agents."
"This medication will delay the absorption of carbohydrates from the intestines." Alpha glucosidase is an enzyme necessary for the absorption of glucose from the GI tract. Inhibiting this enzyme inhibits glucose absorption, delaying rises in postprandial serum glucose levels.

"I take it only when my blood pressure is over 180/80 mm Hg."The patient's statement requires further education, as ARBs should be taken as prescribed daily, not only when blood pressure reaches a certain number.
Which statement by a nursing student about insulin glargine [Lantus] indicates effective learning?
"You cannot mix this insulin in the same syringe with regular insulin." Insulin glargine [Lantus] is a long-acting insulin with a duration of action up to 24 hours. Hence, it can be given at bedtime to provide up to 24 hours of insulin coverage. It should not be mixed with any other insulin. It is given alone because of the low pH of the diluent.
The nurse should include which statement when teaching a patient about insulin glargine [Lantus]?
"You cannot mix this insulin with any other insulin in the same syringe." Insulin glargine [Lantus] is a long-acting insulin with a duration of action up to 24 hours. It should not be mixed with any other insulins. The insulin is not fast acting.

"Growth hormones may not help your height and have side effects." "You have stopped growing and can't take growth hormone."
"You have stopped growing and can't take growth hormone."
Which information should the nurse include in the teaching plan for a patient who has been prescribed repaglinide [Prandin]?
"You will need to be sure you eat as soon as you take this medication." Repaglinide [Prandin] is short acting. The drug's very fast onset of action allows patients to take the drug with meals and skip a dose when they skip a meal. The effects of repaglinide [Prandin] are enhanced when taken with aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), which may result in increased hypoglycemia. Hypoglycemia is a side effect of this medication, and there are many other possible side effects of this medication.

A
The nurse administers candesartan [Atacand] to a patient. Which assessment finding should the nurse use as a clinical indicator of the therapeutic effectiveness of the medication? 1 Blood pressure reduction 2 Serum potassium retention 3 Peripheral perfusion reduction 4 Pulmonary congestion retention
1 All angiotensin receptor blockers (ARBs), such as candesartan [Atacand], are approved for hypertension. Reduction in blood pressure equals those seen with angiotensin-converting enzyme (ACE) inhibitors. ARBs will decrease pulmonary congestion. Because ARBs promote vasodilation, the nurse expects the patient's extremities to be warm and pink from increased perfusion. In contrast to ACE inhibitors, ARBs do not cause clinically significant hyperkalemia.
The nurse is caring for a patient who takes an angiotensin-converting enzyme (ACE) inhibitor. If the patient develops a persistent nonproductive cough, what should the nurse do? 1 Notify the provider of the new development. 2 Tell the patient that the cough will subside in a few days. 3 Assess the patient for other symptoms of upper respiratory infection. 4 Instruct the patient to take antitussive medication until the symptoms subside.
1 Angiotensin-converting enzyme (ACE) inhibitors prevent the breakdown of bradykinins, frequently causing a nonproductive cough. The patient should be switched to a different medication if the side effect cannot be tolerated. The cough will not subside in a few days. This is not a sign of infection but is a known side effect of ACE inhibitors. Medications will not make the cough subside.
The nurse is reviewing the chart for a patient who has been receiving an angiotensin-converting enzyme (ACE) inhibitor for 4 days. Which finding would cause the nurse to hold the ACE inhibitor until evaluated by the patient's primary care provider? 1 Reports sore throat 2 Has bronchial asthma 3 Diabetic with nephropathy 4 No history of renal artery stenosis
1 Sore throat is a sign of neutropenia in a patient receiving an angiotensin-converting enzyme (ACE) inhibitor. Neutropenia, with its associated risk of infection, is a rare but serious complication. Calcium channel blockers (CCB), verapamil, and hydrochlorothiazide can be used safely in patients with bronchial asthma, a condition that precludes the use of beta2-adrenergic antagonists. ACE inhibitors can benefit patients with diabetic nephropathy, slowing the progression of renal disease. ACE inhibitors can cause severe renal insufficiency in patients with bilateral renal artery stenosis or stenosis in the artery to a single remaining kidney; however, this patient has no history of this.
Which statement by a client would lead the nurse to believe that the client has understood the teaching regarding angina? A. Heavy meals and cigarette smoking can precipitate an angina attack. B.There is no correlation between my hypertension and angina C. As long as I take the medicine, I need to make no lifestyle changes D.I will remain inactive because it helps angina

The nurse has just administered the initial dose of enalapril [Vasotec] to a newly admitted patient with hypertension. What is the priority nursing intervention over the next several hours? 1 Check the heart rate. 2 Monitor blood pressure. 3 Auscultate lung sounds. 4 Draw a potassium level.
2 First-dose hypotension is a serious potential adverse effect of angiotensin-converting enzyme (ACE) inhibitors such as enalapril [Vasotec]. Monitoring the blood pressure is the priority nursing intervention. If hypotension develops, the nurse will place the patient in the supine position and possibly increase intravenous fluids. The other interventions may be appropriate for this patient; however, in the hours immediately after the first dose of an ACE inhibitor, monitoring of the blood pressure is most important.
The nurse is administering a prescribed dose of sodium nitroprusside to a patient at 2100 hours. At what time will the nurse anticipate the peak effect of the drug?
2102
The nurse is caring for a patient who takes spironolactone [Aldactone] and quinapril [Accupril] for treatment of heart failure.

4
Which comment by a patient indicates correct understanding about the use of enalapril? 1 "If I feel tired, I should double the dose." 2 "I cannot go out in the sun while on this therapy." 3 "I should stop the drug if I have ringing in my ears." 4 "If I develop a chronic cough, I need to notify my provider."
4 A patient on therapy with an angiotensin-converting enzyme (ACE) inhibitor such as enalapril should report a nonproductive chronic cough, as this is a potential side effect. There is no treatment other than to change the medication therapy. The patient should not double the dose of an antihypertensive. Ringing in the ears in not a concern for ACE inhibitors and the patient need not avoid the sun.
The nurse is preparing discharge teaching for four patients. Which patient should be advised by the nurse that over-the-counter cold and allergy preparations contain phenylephrine and should be avoided? A)A 47-year-old woman with hypertensionB)A 52-year-old man with adult onset diabetes C)A 17-year-old girl with symptoms of an upper respiratory infection D)A 62-year-old man with gout
A Feedback: Phenylephrine, a potent vasoconstrictor and alpha1-agonist with little or no effect on the heart or bronchi, is used in many combination cold and allergy products. Patients with hypertension should avoid these drugs because serious increases in blood pressure could occur. Use of this drug in patients with diabetes and gout are not contraindicated. An upper respiratory infection may be an indication for the drug.
1 (Lidocaine vials should contain clear solution labeled as cardiac or not for cardiac use. The plain solution is used for cardiac conditions. Parenteral solutions of these drugs are usually stable only for 24 hours. Epinephrine is a potent vasoconstrictor that should never be used parenterally.)

Which patients would a nurse identify as being able to safely receive niacin?
A 49-year-old patient with hypertension A 51-year-old patient with chronic obstructive pulmonary disease
C Prednisone (Deltasone) as glucocorticoids can cause gastrointestinal distress and should be administered with food. The normal circadian secretion by the adrenal cortex occurs in the early morning to wake a person up, not early evening. These medications should be tapered slowly to prevent adrenal crisis; they can be administered intravenously as well.
A nursing student is asked to administer prednisone (Deltasone) to a patient. Which statement by the nursing student reflects effective planning? A. "The medication is administered early in the evening to coincide with the natural secretion of the adrenal cortex." B. "The medication is administered on a strict, unchanging schedule to prevent adverse effects." C. "The medication should be administered with food to diminish the risk of gastric irritation." D. "The medication should not be administered intravenously secondary to the risk of hypotension."
3
A parent of a child with head lice asks the nurse when the child may return to school after treatment with permethrin 1% [Nix]. Which response should the nurse make? 1 "When the hair has been cut off 2 inches so that the ova can't hatch." 2 "Two treatments usually are needed within 48 hours, so after that." 3 "After the one-time application and the nits have been removed with a comb." 4 "When family members who have had close contact have been treated."
A
A patient asks the nurse to explain the action of glucocorticoids. Which statement is the nurse's best response? A. "Glucocorticoids influence carbohydrate, lipid, and protein metabolism." B. "Glucocorticoids are produced in decreased amounts during times of stress." C. "Glucocorticoids decrease serum sodium and glucose levels." D. "Glucocorticoids stimulate defense mechanisms to produce immunity."
A Patients who have adrenal suppression may have impaired response to stress because of alterations in epinephrine release. Acetylcholine and dopamine concentrations are not altered by adrenal suppression. Therefore, the patient would not have memory loss, hallucinations, or impaired thinking.
A patient has been prescribed corticosteroids for adrenal suppression. Which behavior process would be observed in the patient because of this? A. Impaired stress response B. Memory loss C. Hallucinations D. Impaired thinking
B (Lidocaine is a sodium channel-blocking drug used specifically to treat ventricular arrhythmias.)
A patient has been prescribed lidocaine (Xylocaine). What does the nurse understand as the reason for this medication order? Bradycardia Ventricular arrhythmias Atrial arrhythmias Heart block
4 (Amphotericin B is toxic to cells of the kidneys. To evaluate renal injury, the plasma creatinine level should be monitored every 3 or 4 days, as well as intake and output. It is not necessary to monitor the serum protein or glucose levels or the serum pH in patients taking amphotericin B.)
A patient is receiving amphotericin B. It is most important for the nurse to monitor which laboratory result? 1 Serum pH 2 Protein level 3 Glucose level 4 Creatinine level
4 (Renal injury from amphotericin B may cause severe hypokalemia. Serum potassium levels should be monitored more frequently and potassium supplements given to correct low plasma levels. Furosemide, insulin, and vitamin K do not prevent any adverse effects of amphotericin B.)
A patient is receiving amphotericin B. The nurse identifies which medication as useful in preventing adverse effects of amphotericin B? 1 Furosemide [Lasix] 2 Insulin 3 Vitamin K 4 Potassium
3

Acyclovir - Acyclovir is indicated for the treatment of genital herpes.
Which action related to drug administration will a nurse expect to take for a patient with unstable ventricular tachycardia?
Administer initial intravenous dose of amiodarone over 10 minutes. For ventricular tachycardia, amiodarone intravenous bolus is to be administered over 10 minutes at 15 mg/min.
Which is the nurse's best action when finding a patient with type 1 diabetes mellitus unresponsive, cold, and clammy?
Administer intravenous glucose. This patient is showing signs of hypoglycemia. In the hospital setting or when the patient is unconscious, intravenous glucose is an obvious option to treat hypoglycemia.
Routine medications were prescribed to resume for a patient who returned from major knee surgery 1 hour ago. The nurse is preparing to administer these medications, including clopidogrel. Which action would the nurse take?
Administer the clopidogrel.
A nurse is preparing to administer enoxaparin, a heparin derivative. Which action by the nurse demonstrates the correct technique for administering the medication?
Administer the drug at least 2 inches from the umbilicus. Enoxaparin is a heparin derivative that is administered deep SQ. The nurse should administer the medication at least 2 inches from the umbilicus.
A nurse is preparing to administer clopidogrel to a patient who has previously complained of dyspepsia 2 hours after taking the drug. Which action would the nurse take?
Administer the drug with a small amount of food. Clopidogrel is rapidly absorbed with or without food. Common side effects include gastrointestinal (GI) distress. The nurse would administer the drug with food to decrease GI distress.
A patient is started on clopidogrel and reports hematuria to the nurse before receiving the morning dose. The nurse has placed a call to the health care provider and is waiting for a response. Which action would the nurse take next?
Administer the medication. When signs of complications such as bleeding occur, the patient should continue taking clopidogrel until the health care provider instructs the patient to stop taking the medication.
The nurse is teaching a patient prescribed captopril [Capoten] for the treatment of hypertension. Which instructions should the nurse include? Select all that apply. A Expect a persistent dry cough. B Take the medication with food. C Expect a sore throat and fever. D Avoid potassium salt substitutes. E Report difficulty in breathing immediately.
A D E Salt substitutes contain potassium and may increase the risk of hyperkalemia with angiotensin-converting enzyme (ACE) inhibitors. A persistent, dry, nonproductive cough may develop. Angioedema includes edema of the tongue, glottis, and pharynx that may cause difficulty breathing, which requires immediate medical attention. Captopril [Capoten] must be taken at least one hour before meals. A sore throat and fever are not expected adverse effects. ACE inhibitors can lower white cell count and decrease the body's ability to fight an infection. Early signs of infection include fever and sore throat.
Sodium Nitroprusside Hypertensive Crisis/Urgency
Adult: IV infusion 0.25 to 10 mcg/kg/min; max 10 mcg/kg/min for 10 min. Monitor blood pressure continuously during administration. Administer via infusion pump only. Solution must be protected from light even during administration. Do not exceed maximum dose due to the risk for thiocyanate toxicity.
4 (The main effects of the antidysrhythmics involve the heart, circulation, and central nervous system (CNS). Specific antidotes are not available, and the management of an overdose involves maintaining adequate circulation and respiration using general support measures (such as CPR) and providing any required symptomatic treatment. Early chest compressions and defibrillation, as indicated, are recommended ASAP by the American Heart Association 2010 guidelines.)
A client has received three times the ordered dose of propafenone (Rythmol) in error. The charge nurse is called into the room and observes that the client is unresponsive with no pulse. What is the nurse's priority action? 1 Administer the reversal agent STAT. 2 Start an IV line with a large bore catheter. 3 Place the client on cardiac monitoring. 4 Begin cardiopulmonary resuscitation efforts.
Hydralazine hypertension
Adult: Initially, PO 10 mg four times a day with gradual increase. Usual maintenance dose is 25 to 100 mg twice a day.
Minoxidil Severe Hypertension
Adult: PO 5 mg/day in 1 to 2 divided doses; max 100 mg/day; usual range 10 to 40 mg/day divided in 1 to 2 doses.Geriatric: PO 2.5 mg/day, may be increased gradually.
2 (When beta blockers are used with an antidysrhythmic, any shortness of breath, weight gain, changes in baseline blood glucose levels, or excess fatigue must be reported to the prescriber immediately. The client is complaining of excess fatigue in this case, because exercise is an activity he "usually' completes without complaint, as inferred from the client's statement.)
A client taking atenolol and amiodarone by mouth complains of not being able to complete his usual exercise routine. The client attributes this complaint to the medication, because the atenolol is a new medication. What is the nurse's best response? 1 "You should not be exercising at all while taking this medication." 2 "You should report your fatigue to your healthcare provider." 3 "Feeling tired is normal when you exercise a lot." 4 "As we age, exercising is a challenge; and fatigue is normal."
3 (If an antacid is needed, it must be taken either 2 hours before or 2 hours after the drug to avoid interference with drugabsorption. An antacid is fine to take, however the more specific instructions of when to take the antacid should be provided to the client. Antidysrhythmics can be taken with food of GI upset occurs.)
A client with a history of gastroesophageal reflux asks the nurse if it is okay to take over the counter medication for heartburn with the newly prescribed antidysrhythmic drug. What is the nurse's best response? 1 "An over the counter antacid is fine to take with your antidysrhtythmic." 2 "It's best to take the antidysrhythmic on an empty stomach if heartburn occurs." 3 "Take an antacid, if needed, 2 hours before or 2 hours after the antidysrhythmic." 4 "You can take an antacid along with the antidysrhythmic 30 minutes before eating."
2

Advise the patient not to take the sildenafil [Viagra].
diet for digoxin
Advise the patient to eat foods high in potassium, such as fresh and dried fruits, fruit juices, and vegetables, including potatoes.
The nurse would most likely administer the combination product isosorbide dinitrate/hydralazine [BiDil] to patients of which ethnic heritage?
African American Isosorbide dinitrate/hydralazine [BiDil] is approved for African Americans who have moderate to severe symptoms. Although it may be given to Asian Americans, Native Americans, or Mexican Americans, it is only approved for a specific group.
While instructing on proper hand-washing technique, which information is most beneficial?
After applying soap and water, rub hands together for at least 15 seconds.
A nurse is providing care to a patient with gout who presents with a fever, rash, eosinophilia, kidney failure, and pancytopenia. Which antigout drug would the nurse suspect has led to this patient's clinical manifestations?
Allopurinol
A patient on thrombolytic therapy experiences severe bleeding. The nurse anticipates the administration of which medication?
Aminocoproic Acid
A 51-year-old male patient has been prescribed lovastatin 40 mg PO each evening to help lower his low-density lipoprotein (LDL) cholesterol. In addition to lovastatin, this patient also takes pantoprazole for gastroesophageal reflux disease (GERD), amiodarone for atrial fibrillation, tamsulosin for benign prostatic hyperplasia, and lisinopril for hypertension. Which medication could cause a potential drug interaction with lovastatin?
Amiodarone
The nurse is preparing to administer a maintenance dose of amiodarone. Which dose would the nurse administer?
Amiodarone 400 mg daily Once arrhythmia has been controlled, amiodarone is lowered to 400 mg once daily.
4 (Itraconazole may cause liver injury, and although a causal link has not been identified, patients need to be informed about symptoms to report. These include jaundice, nausea, and right upper abdominal pain. It is not necessary to take diphenhydramine, wear sunscreen, or avoid citrus products while taking itraconazole.)
A nurse is teaching a patient who is scheduled to start taking itraconazole [Sporanox]. Which statement by the patient would indicate understanding of the teaching? 1 "I'll take diphenhydramine [Benadryl] before this medication so I don't have a reaction." 2 "It's important to remember to wear sunscreen while taking this medicine." 3 "I'll avoid citrus foods, such as oranges and grapefruits, while taking this medication." 4 "If I notice my skin turning yellow or feel any nausea, I'll notify my healthcare provider."
2 (Nystatin is an antifungal medication that is used for candidiasis of the skin, mouth, esophagus, intestine, and vagina. It can be administered orally and topically and will heal mouth lesions from oral candidiasis. Nystatin has no effect on nasal congestion and cough production. It does not cause urticaria.)
A nurse planning care for a patient who is receiving nystatin [Mycostatin] should establish which outcome on the care plan? 1 Relief of nasal congestion 2 Decrease in mouth pain 3 Productive cough 4 Absence of urticaria
The nurse is preparing warfarin for several patients. For which patient would the nurse be most concerned in administering warfarin?
An alcoholic patient with liver disease
1
A nurse should provide which instruction about the application of the medication permethrin 5% [Elimite] to a patient who has scabies? 1 "Apply the medication to the entire body surface in one application." 2 "Rub the medication into your palms and apply it to the area of infestation." 3 "Discard any infested bedding and clothing." 4 "Do not bathe for 48 hours after applying the medication topically."
The nurse is caring for a patient with cryptorchidism who is 28 years old and taking testosterone to treat his condition. What statement by this patient would lead the nurse to believe that he has understood the teaching provided about the drug? A)"My body hair may increase." B)"My sexual desire may increase." C)"My voice may become higher." D)"My skin may become clear and soft."
Ans:A Feedback: Androgenic effects include acne, edema, hirsutism (increased hair distribution), deepening of the voice, oily skin and hair, weight gain, decrease in breast size, and testicular atrophy. Testosterone does not make the skin clear and soft, it does not make the voice higher, and the testicular atrophy is more likely to decrease rather than increase libido.
A 20-year-old female patient has been diagnosed with multiple sclerosis. What drug will most likely be prescribed? A)Baclofen (Lioresal) B)Cyclobenzaprine (Flexeril) C)Metaxalone (Skelaxin) D)Orphenadrine (Banflex)
Ans:A Feedback: Baclofen is used for treatment of muscle spasticity associated with neuromuscular diseases such as multiple sclerosis. Cyclobenzaprine, metaxalone, and orphenadrine are used for relief of discomfort associated with painful, acute musculoskeletal conditions.
The nurse is caring for four patients. Which patient would the nurse expect to have a faster recovery period based only on the process of mitosis? A)A 32-year-old female patient who had surgery for ulcerated colitis B)A 72-year-old man who had surgery for colon cancer C)A 28-year-old woman who had breast reduction surgery D)A 65-year-old man who had surgery for breast cancer
Ans:A Feedback: Cells lining the GI tract reproduce very quickly (72 hours) compared with breast tissue, which takes 2 to 3 months to reproduce. The older the person is, the longer it will take for recovery due to the aging process that reduces rate of circulation of blood cells carrying oxygen to and from cells.
What hormone enters the cell and reacts with a receptor inside the cell to change messenger ribonucleic acid and affect the cell's function? A)EstrogenB)InsulinC)Calcitonin D)Thyroid-stimulating hormone
Ans:A Feedback: Estrogen enters the cell and reacts with a receptor site inside of the cell to make changes and produce an action. This does not happen quickly, and it may take months to years to produce the changes. Estrogen, calcitonin, and thyroid-stimulating hormone react with specific receptor sites on the cell membrane to stimulate change and action within the cell.
The nurse is teaching a class for his or her peers about glucocorticoids. What will the nurse say is initially blocked, resulting in the drug's anti-inflammatory action? A)Arachidonic acid B)Phagocytes C)Lymphocytes D)Antibodies
Ans:A Feedback: Glucocorticoids block the actions of arachidonic acid, which leads to a decrease in the formation of prostaglandins and leukotrienes. They also impair the ability of phagocytes to leave the bloodstream and move to injured tissues; they inhibit the ability of lymphocytes to act within the immune system, including blocking the production of antibodies. Blocking arachidonic acid is, however, the initial action.
A 16-year-old boy is diagnosed with delayed onset of puberty and the physician has ordered testosterone, intramuscular (IM), once every 2 weeks. What nursing intervention would be important to the patient? A)Discuss changes that will occur in his body. B)Have patient fast before injection. C)Have patient reduce protein intake. D)Decrease exercise while on this hormonal treatment.
Ans:A Feedback: It is important for this patient to understand what will happen and the changes he will see to reduce the anxiety that could occur if he didn't understand. Discuss the development of masculine characteristics as well as common adverse effects such as acne. Having the patient fast before the injection would not be necessary, nor would decreasing exercise or reducing protein intake.
A 69-year-old man is prescribed testosterone. The patient is found to have hypertension and a history of congestive failure after assessment by the nurse. What is this patient at increased risk for? A)Fluid retention B)Impotence C)Liver failure D)Kidney failure
Ans:A Feedback: Older adults often have hypertension and other cardiovascular disorders that may be aggravated by sodium and water retention associated with androgens and anabolic steroids. Testosterone would not increase the risk of impotence. Liver and kidney failure could be exacerbated by the drug if they were preexisting conditions but since that is not indicated by the question, this would be a lower risk than fluid retention.
The nurse is teaching the patient about a newly prescribed systemic antifungal drug. What sign or symptom will the nurse instruct the patient to report to the provider immediately? A)Unusual bruising and bleeding B)Constipation or diarrheaC)Red and dry eyesD)Increased appetite with weight gain
Ans:A Feedback:Unusual bruising and bleeding can be an indication of hepatic toxicity, which should be reported immediately. Yellowing of the eyes, not redness, and tearing are also indicative of hepatic toxicity. Usually GI symptoms include nausea and vomiting with antiviral drugs, which could cause decreased appetite and weight loss. These symptoms should be reported if they persist but are not emergency symptoms to report immediately.
The nurse is caring for a patient treated with flumazenil (Anexate) for benzodiazepine toxicity. After administering flumazenil what will the nurse carefully assess for? A)Agitation, confusion, and seizures B)Cerebral hemorrhage and dystonia C)Hypertension and renal insufficiency D)Hypotension, dysrhythmias, and cardiac arrest
Ans:A Feedback: Administration of flumazenil blocks the action of benzodiazepines. If the patient has been taking these medications for an extended period of time, the blockage of the drug's effects could precipitate an acute benzodiazepine withdrawal syndrome with symptoms including agitation, confusion, and seizures. Anexate does not cause cerebral hemorrhage and dystonia, hypertension, renal insufficiency, hypotension, dysrhythmias, and cardiac arrest.
By what route would the nurse administer amphotericin B? A)Intravenously B)Intramuscularly C)Orally D)Topically
Ans:A Feedback: Amphotericin B is only administered by the IV route. It cannot be given intramuscularly, orally, or topically.
The nurse learns a patient receiving a new prescription for oxandrolone takes a lipid- lowering medication daily. What will the nurse tell the patient about this drug interaction? A)Lipid-lowering drug becomes much less effective. combination
Ans:A Feedback: Anabolic steroids may alter lipid metabolism and cause a lack of effectiveness for lipid- lowering agents. Lipid-lowering medications do not impact anabolic steroids and there is no increased risk for toxicity of either drug.
A patient comes to the clinic to receive a Botox injection in her forehead. The patient has adult acne across her forehead. What is the nurse's priority action? A)Hold the injection and consult the health care provider. B)Cleanse the area well with an antibacterial soap. C)Apply a topical antibiotic after administering the Botox. D)Provide patient information about post- Botox injection care.
Ans:A Feedback: Botulinum toxins should not be injected into any area with an active infection because of the risk of exacerbation of the infection. As a result, the nurse would hold the injection and consult with the physician, with the expectation the medication would be held until the acne resolved. Cleansing the area well, applying a topical antibiotic, and providing information about postinjection care would not resolve the problem and are not indicated.
Parents bring a 15-year-old boy into the clinic. The parents tell the nurse that there is a family history of schizophrenia and they fear their son has developed the disease. What symptoms, if described by the family, would support their conclusion? A)"He hears and interacts with voices no one else can hear." B)"He is overactive and always so excitable." C)"He falls asleep in the middle of a sentence." D)"He cannot concentrate and his grades are suffering."
Ans:A Feedback: Characteristics of schizophrenia include hallucinations, paranoia, delusions, speech abnormalities, and affective problems. Overactivity and excitement are associated with mania. Falling asleep suddenly describes narcolepsy. Difficulty concentrating and failing grades is associated with attention deficient disorders.
A local bioterrorism medical team is learning about germ warfare. The team is instructed that a fluoroquinolone may be used to prevent an outbreak of anthrax infection. What fluoroquinolone would the nurse be most likely to administer for this purpose? A)Ciprofloxacin (Cipro) B)Gemifloxacin (Factive) C)Norfloxacin (Noroxin) D)Sparfloxacin (Zagam)
Ans:A Feedback: Ciprofloxacin (Cipro) is the most widely used fluoroquinolone and is indicated for the prevention of anthrax infection. Gemifloxacin and sparfloxacin are most useful in treating acute episodes of chronic bronchitis and community-acquired pneumonia. Norfloxacin is recommended only for certain types of urinary tract infections.
A 75-year-old patient is brought to the emergency department by his family. The family relates that the patient is complaining of confusion, seizures, and abnormal perception of movement. The nurse reviews all of the medication bottles found in the house and suspects the patient overdosed on what medication? A)Benzodiazepine B)Antihypertensive C)Sedative D)Analgesic
Ans:A Feedback: Common manifestations of benzodiazepine toxicity include increased anxiety, psychomotor agitation, insomnia, irritability, headache, tremor, and palpitations. Less common but more serious manifestations include confusion, abnormal perception of movement, depersonalization, psychosis, and seizures. These symptoms are not found in association with options B, C, or D.
When chemotherapeutic agents interfere with cellular physiology, it results in what? A)Cellular death or alterations B)DiffusionC)EndocytosisD)Homeostasis
Ans:A Feedback: Drugs may alter the cell membrane, causing the cell to rupture and die or they may deprive the cell of certain nutrients, altering the proteins that the cell produces. This could interfere with normal cell functioning and cell division. Diffusion is the movement of a substance from a region of higher concentration to a region of lower concentration. Endocytosis involves gathering of material into a cell. Homeostasis refers to keeping the cytoplasm stable within the cell membrane. Diffusion, endocytosis, and homeostasis are not the result of chemotherapeutic agents but may be impacted by the agent.
How does ephedrine act on the body? A)Stimulates the release of norepinephrine B)Acts indirectly on beta-adrenergic receptor sites C)Stimulates the release of dopamine D)Acts indirectly on alpha-adrenergic receptor sites
Ans:A Feedback: Ephedrine stimulates the release of norepinephrine from nerve endings and acts directly on adrenergic receptor sites. Therefore, the other options are incorrect.
The nurse attributes what assessment finding to the use of androgens by the male patient? A)Testicular atrophy B)Increased fertility C)Increased urination D)Hoarseness
Ans:A Feedback: In adult men, adverse effects include inhibition of testicular function, gynecomastia, testicular atrophy, priapism, baldness, and change in libido. Increased fertility, increased urination, and hoarseness would not be expected assessment findings.
The nurse is caring for a newborn who was delivered from a woman who took benzodiazepines for anxiety during the last 2 months of her pregnancy after her husband was killed in war. What will the nurse assess for in this newborn? A)Newborn withdrawal syndrome B)Hepatic dysfunctionC)Failure to thriveD)Learning deficiencies
Ans:A Feedback: Neonatal withdrawal syndrome may result in a baby born to a mother who was taking benzodiazepines in the final weeks of pregnancy. The neonate may be given very small doses of benzodiazepines that are withdrawn gradually to prevent symptoms. Hepatic dysfunction in the neonate is not associated with use of benzodiazepines. Failure to thrive and learning deficiencies would be long-term problems and are not assessed during the neonatal period.
When spinal reflexes involve synapses with interneurons within the spinal cord, what physiological adjustments are made? A)Coordinate movement and position B)Adjust response and recovery C)Adjust to upright position D)Coordinate balance
Ans:A Feedback: Other spinal reflexes may involve synapses with interneurons within the spinal cord, which adjust movement and response based on information from higher brain centers to coordinate movement and position. Spinal reflexes do not adjust response and recovery, adjust the body to the upright position, or coordinate balance.
The nurse is caring for a patient who is scheduled for abdominal surgery in the morning and is scheduled to receive rocuronium (Zemuron). The patient asks the nurse to describe the adverse effects of rocuronium. What would the nurse describe for the patient? A)"This drug is associated with pulmonary hypertension." B)"This drug contains benzyl alcohol." C)"This drug is associated with bradycardia." D)"This drug is associated with an increased heart rate."
Ans:A Feedback: Rocuronium may be associated with pulmonary hypertension. Cisatracurium (Nimbex) contains benzyl alcohol; Atracurium (Tracrium) is associated with bradycardia; and Pancuronium (Pavulon) is associated with an increased heart rate.
What helmintic infestation occurs in tropical areas and is carried by snails? A)Schistosomiasis B)Platyhelminths C)Trichinosis D)Filariasis
Ans:A Feedback: Schistosomiasis is a common problem in many tropical areas where the snail that is necessary in the life cycle of the fluke lives. Trichinosis is caused by eating undercooked pork and can occur in any part of the world. Filariasis and platyhelminths are not restricted to tropical areas.
What substances move freely in and out of a cell by diffusion? A)Electrolytes B)Enzymes C)Hormones D)Proteins
Ans:A Feedback: Sodium, potassium, calcium, carbonate, oxygen, bicarbonate, and water move freely in and out of cells. These substances move through channels or pores in the cell membrane through movement from a region of higher concentration to a region of lower concentration. Hormones, enzymes, and proteins are considered carriers. If a substance cannot move freely on its own, it may attach itself to another carrier to be diffused.
A public health nurse is speaking to parents of first graders. When discussing worm infection, the nurse will explain that the most common type found in U.S. school-aged children is what? A)Pinworms B)Roundworms C)Threadworms D)Whipworms
Ans:A Feedback: The most common worm infection encountered in U.S. school-aged children is pinworms. These worms are endogenous to the area and easily spread. Roundworms, whipworms, and threadworms are not as common.
The patient presents to the emergency department with muscle spasms in the back. What types of injury would the nurse recognize can result in muscle spasm? (Select all that apply.) A)Overstretching a muscle B)Wrenching a jointC)Tearing a tendon or ligament D)Breaking a bone E)Exercising too vigorously.
Ans:A, B, C Feedback: Muscle spasms often result from injury to the musculoskeletal system (e.g., overstretching a muscle, wrenching a joint, tearing a tendon or ligament). These injuries can cause violent and painful involuntary muscle contractions. Breaking a bone or exercising would not cause muscle spasms unless one of the other options was involved.
The nurse is preparing a class on the endocrine system for students. What benefit is served by the positioning of the hypothalamus in the brain? (Select all that apply.) A)Close to other important areas of the brain B)Able to influence and be influenced by emotions and thoughts C)Poorly protected by the blood-brain barrier D)Floats within ventricles of the brain E)Protected from the limbic system
Ans:A, B, C Feedback: Situated at the base of the forebrain, the hypothalamus receives input from virtually all other areas of the brain, including the limbic system, cerebral cortex and the special senses that are controlled by the cranial nerves: smell, sight, touch, taste, hearing. Because of its positioning, the hypothalamus is able to influence, and be influenced by, emotions and thoughts. The hypothalamus also is located in an area of the brain that is poorly protected by the blood-brain barrier, so it is able to act as a sensor to various electrolytes, chemicals, and hormones that are in circulation and do not affect other areas of the brain. It does not float within the ventricles of the brain, and it is located to allow input from the limbic system.
The nurse, working in the preoperative holding area, is caring for a 70-year-old patient who is scheduled to receive succinylcholine as part of general anesthesia. When collecting the nursing history, what condition would require the nurse to notify the anesthesiologist of the need for caution? A)Bone fracture B)MalnutritionC)Fluid volume overload D)Narrow-angle glaucoma E)Pregnancy
Ans:A, B, DFeedback: Succinylcholine should be used with caution in patients with fractures because the muscle contractions it causes might lead to additional trauma; in patients with narrow-angle glaucoma or penetrating eye injuries because intraocular pressure increases. Extreme caution is necessary in the presence of genetic or disease-related conditions causing low plasma cholinesterase levels (e.g., cirrhosis, metabolic disorders, carcinoma, burns, dehydration, malnutrition, hyperpyrexia, thyroid toxicosis, collagen diseases, exposure to neurotoxic insecticides).
A 3-year-old girl with a diagnosis of spasticity caused by cerebral palsy has been admitted to the unit. The physician has ordered dantrolene to see if it relieves the spasticity in the child's arms and hands. The nurse would schedule this child for what routine screenings? A)Central nervous system and gastrointestinal (GI) function B)Respiratory and cardiovascular (CV) function C)Growth and development D)Renal and hepatic function
Ans:AFeedback: Children prescribed dantrolene should be routinely and regularly screened for central nervous system and gastrointestinal (including hepatic) toxicity. Growth and development should be routinely screened in all children. Renal, respiratory, and CV screening is not indicated.
A patient with severe spasticity sees his physician. The physician orders dantrolene. In what circumstances is the drug dantrolene contraindicated? A)Spasticity that contributes to upright position B)Spasticity that involves both legs C)Spasticity that involves the arm and the leg on the same side D)Spasticity that contributes to mobility
Ans:AFeedback: Dantrolene is contraindicated in the presence of any known allergy to the drug. It is also contraindicated in the following conditions: spasticity that contributes to locomotion, upright position, or increased function, which would be lost if that spasticity was blocked; active hepatic disease, which might interfere with metabolism of the drug and because of known liver toxicity; and lactation because the drug may cross into breast milk and cause adverse effects in the infant. The other options would not contraindicate the medication.
When fluoxymesterone (Androxy) is administered to a 14-year-old boy for hypogonadism, what is the expected result? A)Enlarged sex organs B)Decreased skin thickness C)Increased protein metabolism D)Increased sperm production
Ans:AFeedback: In prepubertal boys, administration of male sex hormone-like drugs will stimulate development of masculine characteristics and cause development of the male sexual organs. Production of sperm will occur when the boy enters puberty. These drugs are not administered to decrease skin thickness or increase protein metabolism.
The nurse is admitting a mental health patient and collects the medication history. The patient says he takes Haldol, midodrine, hydrochlorothiazide, acetaminophen, and Cymbalta. The nurse will call the provider to discuss what dangerous drug combination? A)Haldol and midodrine B)Hydrochlorothiazide and midodrine C)Cymbalta and midodrine D)Acetaminophen and midodrine
Ans:AFeedback: Midodrine can precipitate increased drug effects of digoxin, beta-blockers, and many antipsychotics. Such combinations should be avoided. The other drug combinations do not pose any immediate concerns.
The physician has ordered olanzapine (Zyprexa) for a new patient. What laboratory test should be done before administration of olanzapine? A)Blood glucoseB)Urine specific gravity C)CholesterolD)Hemoglobin and hematocrit
Ans:AFeedback: Olanzapine has been associated with weight gain, hyperglycemia, and initiation or aggravation of diabetes mellitus. Other options are not necessary for patients taking olanzapine unless a secondary diagnosis indicates a need.
32. Nursing care for the postoperative patient requiring long-term glucocorticoid therapy will be directed at overcoming what adverse effect of the drug? A)Poor wound healing B)Inflammation C)Autoimmune response D)Lack of mobility
Ans:AFeedback: Patients taking long-term glucocorticoid therapy will have impaired wound healing so nursing care is directed toward promoting healing. The drug has an anti-inflammatory effect so that would not need to be overcome. There is no autoimmune response or lack of mobility so these do not have to be overcome.
The nurse is discussing the endocrine system with a class of nursing students. What substance would the nurse label as a hormone? A)Acetylcholine B)Norepinephrine C)Nucleic acid D)Serotonin
Ans:B Feedback: A hormone is secreted directly into the bloodstream and travels from the site of production to react with specific receptor sites to cause an action. Norepinephrine, which is a neurotransmitter, is a hormone when it is produced in the adrenal medulla, secreted into circulation, and travels to norepinephrine receptor sites to cause an effect. Acetylcholine and serotonin are neurotransmitters, but are not hormones. Nucleic acid is used to build deoxyribonucleic acid and ribonucleic acid.
The nurse is caring for a patient who received succinylcholine during surgery. The nurse would expect the patient to spend more time in the postanesthesia care unit due to prolonged paralysis and inability to breathe if the patient was from what ethnic group? A)American Japanese B)Alaskan Eskimos C)Native Americans D)Hawaiian natives
Ans:B Feedback: Alaskan Eskimos belong to a genetic group that is predisposed to low plasma cholinesterase levels, making them susceptible to prolonged paralysis after succinylcholine use. The other ethnic groups do not have this genetic predisposition.
The nurse admits a 1-year-old child to the pediatric intensive care unit (ICU) with cryptococcal meningitis. What drug will the nurse anticipate receiving an order for to treat this child? A)Amphotericin B (Fungizone) B)Fluconazole (Diflucan) C)Griseofulvin (Fulvicin) D)Ketoconazole (Nizoral)
Ans:B Feedback: Fluconazole is used in the treatment of cryptococcal meningitis and is safe to use in a 1-year-old child. Amphotericin B has many unpleasant adverse effects and is very potent, so it would not be the first or best medication to administer initially but would be reserved for use if fluconazole was not effective. Griseofulvin is given to treat tinea pedis and tinea unguium in children. Ketoconazole is not given to children younger than 2 years because safety has not been established.
Which drug does not have a recommended pediatric dose? A)Pimozide (Orap) B)Lithium salts (Lithotabs) C)Haloperidol (Haldol) D)Risperidone (Risperdal)
Ans:B Feedback: Lithium does not have a recommended pediatric dose; the drug should not be administered to children younger than 12 years old. Pimozide, haloperidol, and risperidone all have recommended pediatric doses.
The nurse gives a class at the local high school on the use of anabolic steroids. The nurse explains that one of the most serious and all too common side effects of using these drugs without a prescription and medical follow-up is what? A)Renal stonesB)DeathC)CirrhosisD)Malignant hyperthermia
Ans:B Feedback: Prolonged use of high doses may cause potentially life-threatening conditions, placing the patient at risk of death. Conditions such as peliosis hepatis, hepatic neoplasms, and hepatocellular carcinoma are often seen with high-dose street use of these drugs. Renal stones, cirrhosis, and malignant hyperthermia are not associated with the use of anabolic steroids.
A mother brings her child to the clinic where the child is diagnosed with hookworms. The mother asks how the child got hookworms. What would the nurse tell the mother is the route of entry for hookworm? A)InhalationB)Contact with skinC)Ingestion of undercooked foods D)Blood-borne exposure
Ans:B Feedback: The larvae penetrate the skin and then enter the blood and within about a week, reach the intestine. Inhalation, ingestion, and blood- borne exposure are incorrect.
The nurse is caring for a patient in intensive care unit receiving IV lorazepam (Ativan) to reduce anxiety related to mechanical ventilation. While injecting the medication the nurse notes a decrease in blood pressure and bradycardia. What is the nurse's priority action? A)Discontinue drug administration. B)Give the IV drug more slowly.C)Notify the patient's health care provider. D)Document the reaction to the drug.
Ans:B Feedback: The nurse's priority action is to slow the rate of injection because rapid injection of benzodiazepines can result in hypotension and bradycardia and can lead to cardiac arrest.
What receptors in the body stimulate the hypothalamus to release antidiuretic hormone (ADH)? A)Diuretic receptors B)Osmoreceptors C)Alpha receptors D)Nicotinic receptors
Ans:B Feedback: The osmoreceptors in the hypothalamus stimulate the release of ADH. There is no such thing as a diuretic receptor. Alpha receptors are associated with the sympathetic nervous system and nicotinic receptors are associated with the parasympathetic nervous system.
What hormones does the adrenal medulla secrete? A)Renin and erythropoietin B)Norepinephrine and epinephrine C)Epinephrine and dopamine D)Dopamine and serotonin
Ans:B Feedback:The adrenal medulla is actually part of the sympathetic nervous system (SNS). It is a ganglion of neurons that releases the neurotransmitters norepinephrine and epinephrine into circulation when the SNS is stimulated.
A patient is taking aminophylline for their chronic obstructive pulmonary disease. The patient is about to undergo emergency surgery and will receive an neuromuscular junction (NMJ) blocker as part of the procedure. It is important for the nurse to take what action? A)Make sure the patient receives the aminophylline on a regular schedule to maintain therapeutic levels. B)Monitor the patient very closely for signs of early arousal and return of muscle function. C)Carefully explain all that is going on because the patient will be unable to talk. D)Switch the patient to theophyllines before the procedure begins.
Ans:B Feedback: Aminophylline can cause a decreased effectiveness of NMJ blockers, leading to reduced paralysis and early return of movement. If a patient has emergency surgery and has been taking aminophylline, the patient should be carefully monitored for early arousal and return of movement. The patient will not be awake during surgery using an NMJ blocker and will be intubated to ensure respirations. Aminophylline and other xanthine derivatives like the theophyllines will have the same effect.
A patient has been prescribed sildenafil citrate. What should the nurse teach the patient about this medication? A)Take the medication with a glass of grapefruit juice. B)The drug should be taken 1 hour before attempting intercourse. C)Facial flushing or headache should be reported to the physician immediately. D)A dose exceeding 80 mg will result in a change of vision, making everything appear blue.
Ans:B Feedback: The drug should be taken approximately 1 hour before intercourse to allow adequate time for absorption and therapeutic effects to occur. Facial flushing, mild headache, indigestion, and running nose are common side effects of sildenafil citrate and do not need to be reported unless they become acute. The "blue haze" that occurs with the 100-mg dosage is transient (it lasts about 1 hour). Grapefruit juice should be avoided 2 days before until 2 days after taking the medication because it prolongs the drugs metabolism and excretion.
The patient's body modulates pain perception as a result of the production of what in the intermediate lobe of the pituitary gland? A)Antidiuretic hormone (ADH) B)EndorphinsC)Adrenocorticotropic hormone (ACTH) D)Oxytocin
Ans:B Feedback: Endorphins and enkephalins are produced by the intermediate lobe of the pituitary gland. Oxytocin and ADH are produced by the posterior pituitary gland, and ACTH is produced by the anterior pituitary gland.
When hormones, formed within the cell, move across the cell membrane, the process is called what? A)Endocytosis B)Exocytosis C)Phagocytosis D)Pinocytosis
Ans:B Feedback: Exocytosis is the movement of substances such as waste products, hormones, and neurotransmitters out of the cell. Pinocytosis is the movement of nutrients and needed substances into the cell through specific receptors on the cell surface. Phagocytosis involves the destruction of engulfed proteins or bacteria. Endocytosis involves incorporation of material into the cell.
The pharmacology instructor is discussing the histocompatibility of the cell. What is the importance of a cell's histocompatibility antigen? A)It reproduces cells when other cells die. B)It recognizes cells as self-cells that belong in the body. C)The antigen produces antibodies to viral invaders. D)The antigen stimulates the production of white blood cells.
Ans:B Feedback: The histocompatibility antigens are proteins that are seen on the top of the cell membrane. T cells use these antigens as the identifying proteins that identify a cell as a self-cell. If these antigens are not present on a cell membrane, the T cells will destroy that cell, determining that it is foreign. The histocompatibility antigens are not involved in reproduction. They do not produce antibodies nor do they stimulate white blood cell production.
The nurse evaluates teaching as effective when a patient taking a benzodiazepine states, A)"I should always take the medication with meals." B)"I should not stop taking this drug without talking to my health care provider first." C)"I cannot take aspirin with this medication." D)"I will have to take this medication for the rest of my life."
Ans:B Feedback: The patient makes a correct statement when saying the drug should not be stopped without talking to the health care provider first because withdrawal of benzodiazepines require careful monitoring and should be gradually withdrawn. Medications do not have to be taken with food, aspirin is not contraindicated, and the medication need only be taken while the condition being treated continues. Patients with anxiety may only need the medication for a few weeks whereas those with a seizure disorder may take it for longer periods of time.
What are the simplest nerve pathways in the body? A)Arc reflexesB)Spinal reflexes C)Afferent nerve reflexes D)Spindle gamma loop
Ans:B Feedback: The spinal reflexes are the simplest nerve pathways that monitor movement and posture. Arc reflexes and afferent nerve reflexes are distracters for this question. Spindle gamma loops respond to stretch receptors.
A group of nursing students are developing a presentation on hormones. What hormone will the students' presentation identify as regulating the metabolic rate and influencing the growth and development of the body? A)Parathyroid hormone or parathormone B)Thyroid hormoneC)CortisolD)Insulin
Ans:B Feedback: Thyroid hormone regulates the metabolic rate of the body and greatly influence growth and development. Parathormone, cortisol, and insulin do not regulate the metabolic rate or influence growth and development.
The nurse is caring for a patient who is taking a benzodiazepine. The nurse knows that caution should be used when administering a benzodiazepine to the elderly because of what possible adverse effect? A)Acute renal failure B)Unpredictable reactions C)Paranoia D)Hallucinations
Ans:B Feedback: Use benzodiazepines with caution in elderly or debilitated patients because of the possibility of unpredictable reactions and in patients with renal or hepatic dysfunction, which may alter the metabolism and excretion of these drugs, resulting in direct toxicity. Dosage adjustments usually are needed for such patients. Acute renal failure, paranoia, and hallucinations are not commonly related to therapy with these medications in the elderly.
A patient who has a tinea infection calls the clinic and complains of intense local burning and irritation with use of a topical antifungal drug. Even before asking the patient, the nurse suspects he or she is applying what medication? A)Butoconazole (Gynazole I) B)Ciclopirox (Loprox) C)Econazole (Spectazole) D)Haloprogin (Halotex)
Ans:C Feedback: Econazole can cause intense local burning and irritation in treatment of tinea infections. Butoconazole is used to treat vaginal Candida infections. Ciclopirox is used to treat toenail and fingernail tinea infections and does not produce intense burning and irritation. Haloprogin is used to treat athlete's foot, jock itch, and ringworm infections and is not associated with burning or irritation.
Hypnotic drugs are used to aid people in falling asleep. What physiological system does a hypnotic act on to be effective in helping a patient to sleep? A)Limbic system B)Sympathetic nervous system C)Reticular activating system D)Lymph system
Ans:C Feedback: Hypnotics are used to help people fall asleep by causing sedation. Drugs that are effective hypnotics act on the reticular activating system and block the brain's response to incoming stimuli. Hypnosis, therefore, is the extreme state of sedation, in which the person no longer senses or reacts to incoming stimuli. The other options are incorrect.
A patient with high cholesterol is taking lovastatin (Mevacor). What drug would the nurse question if it was ordered for this patient? A)Nifedipine (Procardia) B)Ciprofloxacin (Cipro) C)Itraconazole (Sporanox) D)Oxazepam (Serax)
Ans:C Feedback: Itraconazole is an azole antifungal drug that has been associated with severe cardiovascular events when taken with lovastatin. Nifedipine, ciprofloxacin, and oxazepam have no drug interactions with lovastatin. Nifedipine is an antihypertensive drug whose effects can be increased when taken with cimetidine. The effects of ciprofloxacin are altered when taken with antacids and theophyllines. Oxazepam is an antianxiety drug that should not be taken with alcohol or theophyllines.
What antiepileptic medication might the nurse administer to treat bipolar disorder? A)Apriprazole (Abilify) B)Cyclobenzaprine (Flexeril) C)Lamotrigine (Lamictal) D)Temazepam (Restoril)
Ans:C Feedback: Lamotrigine is an antiepileptic agent used for long-term maintenance of patients with bipolar disorders because it decreases occurrence of acute mood episodes. Apriprazole is an atypical antipsychotic and is not an antiepileptic medication. Flexeril is a muscle relaxant and Temazepam is a hypnotic agent. None of these medications are indicated for the treatment of bipolar disorder.
A 32-year-old female patient is admitted to the floor with a superinfection. Her orders read tigecycline (Tygacil) 100 mg IV followed by 50 mg IV every 12 hours infused over 30 to 60 minutes for 5 days. What would be important for the nurse to educate this patient about? A)Analgesics B)Antihistamines C)Contraceptives D)Decongestants
Ans:C Feedback: Many antibiotics interfere with the effectiveness of oral contraceptives and unplanned pregnancies can occur. Women should be advised to use a barrier form of contraceptives when taking this drug. No known serious drug-drug interactions involve analgesics, antihistamines, or decongestants.
A mother of a 3-year-old child brings her child to the clinic. The child is diagnosed with pinworms. What drug would be the best choice for the patient? A)Pyrantel (Pin-Rid) B)Ivermectin (Stromectol) C)Mebendazole (Vermox) D)Albendazole (Albenza)
Ans:C Feedback: Mebendazole is the most commonly used anthelmintic for pinworms because it is available in a chewable tablet. This is a good choice for the 3-year-old patient. Pyrantel is also prescribed for pinworms but is not available in a chewable form. Ivermectin is prescribed for treatment of threadworm disease and albendazole is given to treat active lesions caused by pork tapeworm and cystic disease of the liver, lungs, and peritoneum caused by dog tapeworm.
Which of these body cells has the greatest number of mitochondria? A)Tibia bone cells B)Breast tissue C)Cardiac muscle D)Subcutaneous skin
Ans:C Feedback: Mitochondria are very abundant in cells that consume energy. The cardiac muscle cells, which must work continually to keep the heart contracting, contain a great number of mitochondria. Milk-producing cells in breast tissue, which are normally dormant, contain very few. Cells of bone and of subcutaneous tissue do not consume a great deal of energy; therefore, they have smaller numbers of mitochondria than cardiac muscle.
A patient is to have surgery and it is planned that atracurium (Tracrium) is to be used as an adjunct to general anesthesia. How will the atracurium work? A)Act as agonist to acetylcholine B)Stops depolarization in the axion C)Act as antagonist to acetylcholine D)Stops repolarization in the axion
Ans:C Feedback: Nondepolarizing neuromuscular junction blockers compete with acetylcholine (ACh) for the ACh receptor site and after they occupy the site, stimulation cannot occur. This results in paralysis because the muscle cannot respond. Other options are incorrect.
A clinic nurse is caring for a 66-pound child who has acute otitis media. The physician has ordered ceftibuten (Cedax) 9 mg/kg per day PO for 10 days. The drug comes in an oral suspension of 90 mg/5 mL. How many mL will the nurse administer? A)5 mL B)10 mL C)15 mL D)20 mL
Ans:C Feedback: First, using the formula: 2.2 lb/1 kg = 66 lb/X kg, determine the child's weight in kg (66/2.2 = 30 kg). Next, determine the desired dose by using the formula: amount of prescribed drug times weight in kg (9 mg/kg times 30 kg = 270 mg). To determine the volume of medication to administer, use the formula: amount of drug available/volume available = amount of drug prescribed/volume to administer (90 mg/5 mL = 270 mg/X mL, 90mg/(X) = 1,350 mg/mL, X = 15 mL).
The nurse is caring for a patient who works night shift from 2200 (10 pm) to 0600 (6 am) and normally sleeps from 0800 (8 am) until 1600 (4 pm) each day. The nurse would teach this patient to take his or her corticosteroid at what time of the day? A)06:00 (6 am) B)08:00 (8 am) C)16:00 (4 pm) D)22:00 (10 pm)
Ans:C Feedback: If a person works all night and goes to bed at 8 am, arising at 4 pm to carry on the day's activities before going to work at 10 pm, the hypothalamus will release corticotropin- releasing hormone at about 4 pm in accordance with the new sleep-wake cycle. It usually takes 2 or 3 days for the hypothalamus to readjust. A patient on this schedule who is taking replacement corticosteroids would then need to take them at 4 pm, or on arising. All other options would not be optimal.
The nurse is caring for four patients. Which patient would have the highest risk for hepatotoxicity from dantrolene (Dantrium)? A)An 87-year-old man who is taking a cardiac glycosideh B)A 32-year-old man who is taking an antipsychotic drug C)A 65-year-old woman who is on hormone replacement therapy D)A 48-year-old woman who is taking an antihypertensive agent
Ans:C Feedback: If dantrolene is combined with estrogen, the incidence of hepatocellular toxicity is increased. This combination should be avoided. Nothing indicates that patients taking a cardiac glycoside, an antipsychotic drug, and an antihypertensive would have serious adverse effects when combined with dantrolene therapy.
The patient is prescribed sildenafil 25 mg PO one hour before sexual intercourse is planned. The patient returns for follow-up care and says that 25 mg did not produce an erection so he increased the dosage. How much of an increase would be enough to concern a nurse? A)50 mg B)75 mg C)100 mg D)25 mg
Ans:C Feedback: Normal dosage range is 25 to 100 mg so the nurse should not be concerned unless the dosage exceeded 100 mg.
The nurse is teaching the soon-to-be- discharged patient, diagnosed with schizophrenia, about his medications. What is a priority teaching point for this patient? A)The patient must eat three nutritious meals daily. B)Over-the-counter medications may be taken with antipsychotic drugs. C)Cough medicines potentiate the actions of antipsychotic drugs. D)Alcohol consumption should be avoided.
Ans:DFeedback: Alcohol consumption should be avoided because it increases the central nervous system (CNS) effects of the drug and may cause excessive drowsiness and decreased awareness of safety hazards in the environment. Some patients may find it easier and more effective to eat five small meals rather than three nutritious meals. While promoting good nutrition is good practice, it is not the priority. Drug-drug interactions with antipsychotic drugs are common so the nurse would teach the patient not to take any medication without consulting with the doctor or a pharmacist to make sure it is safe.
What would be a priority nursing action related to the care of a patient taking albendazole (Albenza)? A)Check blood pressure, pulse, and respirations B)Weigh the patientC)Monitor renal function D)Encourage small, frequent meals
Ans:CFeedback: It is important that the patient's kidney function be monitored because a serious adverse effect of this drug is renal failure. Even though vital signs, weight, and nutrition are important and should be monitored, if the patient exhibits any signs of renal failure the drug should be stopped immediately.
What is the function of the mitochondria within the cell? A)Convert small substances into energy B)Convert hormones into secretory substances C)Produce energy in the form of adenosine triphosphate (ATP) D)Move electrolytes into and out of a cell
Ans:CFeedback: Mitochondria are rod-shaped organelles that produce energy in the form of ATP for use by cells. They do not convert small substances into energy; they do not convert hormones into secretory substances; and they do not move electrolytes into and out of a cell.
A 9-year-old boy is taking testosterone injections for treatment of hypogonadism. What should be measured every 6 months on this child? A)Liver function test (LFT) B)Cholesterol levelC)VisionD)hand and wrist radiographs
Ans:DFeedback: Because of the effects of these hormones on epiphyseal closure, children should be closely monitored with hand and wrist radiographs before treatment and every 6 months after treatment. It would not be necessary to measure LFTs, cholesterol levels, or the child's vision.
The nurse is providing discharge teaching to a patient who is being sent home on oral tetracycline (Sumycin). What instructions should the nurse include? A)Take the medication only once a day. B)Check pulse rate and hold the drug if lower than 60 beats per minute (bpm). C)Take the drug on an empty stomach. D)Take the medication with 2 ounces of water.
Ans:CFeedback: Tetracycline should be taken on an empty stomach 1 hour before or 2 hours after meals with a full 8 ounces of water to ensure full absorption. Tetracycline is usually taken at least once every 12 hours. Checking the pulse and holding the dose if below 60 bpm is an action specific to the use of cardiac glycosides.
A 78-year-old woman, who lives alone and is forgetful, is being seen by her home health nurse. In reviewing the patient's medication, the nurse discovers that the patient is taking Azithromycin (Zithromax) for urethritis. Why would this be a good choice of antibiotics for this patient? A)The half-life of the drug is 3 to 7 hours. B)It is taken only once a day. C)It has very few adverse effects. D)It can be given without consideration to drug-drug interactions.
Ans:B Feedback: Given that the patient is "forgetful" and lives alone, a daily dose would likely promote improved compliance. Azithromycin can be administered once daily because the half-life is 68 hours. Azithromycin is associated with GI adverse effects and can cause pseudomembranous colitis; neurological symptoms can occur as well. Azithromycin (Zithromax) may adversely interact with cardiac glycosides, oral anticoagulants, theophyllines, carbamazepine, and corticosteroids to name a few agents.
The nurse explains the purpose of the negative feedback system used by the endocrine system is what? A)To change the environment of the pituitary gland B)To regulate hormone release C)To maintain hormone concentration at a certain level D)To control the action of hormones
Ans:CFeedback: The negative feedback system is a control system in which increasing levels of a hormone lead to decreased levels of releasing and stimulating hormones, leading to decreased hormone levels, which stimulates the release of releasing and stimulating hormones; it allows tight control of the endocrine system. It does not involve changing the environment or control the action of hormones.
The nursing students are studying sympathomimetic drugs. How do these drugs act on the body? A)Stimulate beta receptors and block alpha- receptors B)Stimulate alpha-receptors and block beta- receptors C)Block adrenergic receptorsD)Stimulate both alpha and beta-receptors
Ans:D Drugs that are generally sympathomimetic are called alpha-agonists (stimulate alpha- receptors) and beta-agonists (stimulate beta- receptors). These agonists stimulate all of the adrenergic receptors; that is they affect both alpha and beta-receptors.
A patient is having outpatient surgery that should last only 45 minutes. The patient is planning to go home immediately after the surgery is complete. What nondepolarizing neuromuscular junction blocker will most likely be used as an adjunct therapy to general anesthesia for this patient? A)Atracurium (Tracrium) B)Cisatracurium (Nimbex) C)Pancuronium (Pavulon) D)Rocuronium (Zemuron)
Ans:D Fedback: Rocuronium has a rapid onset of action and a short duration, making it a drug of choice for outpatient surgical procedures when the patient will be leaving to go home and will need to be awake, alert, and mobile. Atracurium, cisatracurium, and pancuronium are associated with longer paralysis and recovery.
Why is it important for a nurse to inquire about any foreign travel of a patient with a suspected lymphatic or hematologic disorder? A)To determine the varied sexual history of the patient, if any B)To determine the potential exposure to infectious agents C)To determine whether the patient has had any blood transfusions D)To determine whether the patient adopted any specific dietary habits
Ans:B Feedback: Knowledge of recent travel can help the nurse to pinpoint potential exposure to helminths, parasites, or other infection exposure common in the area visited. The nurse should specifically ask about foreign travel to countries where malaria or parasitic roundworms are common. Sexual history, dietary habits, or any blood transfusions that the patient may have had before would not be adequately explored by questioning travel history.
A 55-year-old man presents at the clinic complaining of erectile dysfunction. The patient has a history of diabetes mellitus. The physician orders tadalafil (Cialis) to be taken 1 hour before sexual intercourse. The nurse reviews the patient's history before instructing the patient on the use of this medication. What disorder (or condition) would contraindicate the use of tadalafil (Cialis)? A)Cataracts B)Penile implant C)Hypotension D)Lung cancer
Ans:B Feedback: Patients with a penile implant should not take tadalafil. Patients with cataracts, hypotension, or lung cancer may take tadalafil if needed but should do so with caution and should be carefully monitored for adverse effects.
When a cell uses energy to move ions against an electrical or chemical gradient, what is the process called? A)Passive transport B)Neutral transport C)Cotransport D)Active transport
Ans:D Feedback: Active transport is what happens when cells use energy to move ions against an electrical or chemical gradient. Passive transport is another term for diffusion. There is no such thing as neutral transport. Cotransport is when the sodium ion and the solute are transported in the same direction.
The nurse is teaching the mother of a child diagnosed with attention-deficit hyperactivity disorder how to administer methylphenidate (Ritalin). When would the nurse instruct the mother to administer this drug? A)"Administer at lunch every day." B)"Administer at breakfast every day." C)"Administer at dinner every day." D)"Administer at bedtime."
Ans:B Feedback: Several long-acting formulations of methylphenidate have become available that allow the drug to be given only once a day. It should always be given in the morning because administration at dinnertime or bedtime could result in insomnia.
The nursing instructor is discussing helmintic infections with the nursing students. How would the instructor explain the action of anthelmintic drugs? A)Destroy the nervous system of the invading worm B)Act on metabolic pathways that are present in the invading worm C)Interfere in the reproductive cycle of the invading worm D)Cause fatal mutations in the deoxyribonucleic acid of the invading worm
Ans:B Feedback: The anthelmintic drugs act on metabolic pathways that are present in the invading worm, but that are absent or significantly different in the human host. Other options are incorrect descriptions of how anthelmintic drugs work.
Why would the nurse expect the patient with liver disease to receive a smaller dose of benzodiazepines? A)Excretion of the drug relies on liver function. B)The drugs are metabolized extensively in the liver. C)They are lipid soluble and well distributed throughout the body. D)The drugs are well absorbed from the gastrointestinal tract.
Ans:B Feedback: The benzodiazepines are metabolized extensively in the liver. Patients with liver disease must receive a smaller dose and be monitored closely. Excretion is primarily through the urine. All of the answer options are true, but only the fact that the benzodiazepines are metabolized in the liver explains why a patient with liver disease would require smaller dosages.
An 85-year-old man who is a resident in an extended-care facility has athlete's foot. After applying an antifungal cream, what is the nurse's next action? A)Wipe away excess medication from the affected area. B)Wrap a sterile kling dressing around both feet. C)Elevate the feet for 30 minutes. D)Apply clean dry socks.
Ans:DFeedback: Clean dry socks should be applied when treating athlete's foot to help eradicate the infection because they will keep the feet dry as well as prevent the cream from being wiped away. A kling dressing is not necessary as it would bind the feet and interfere with mobility and increase the risk of systemic absorption. Medication should not be removed once applied, and there is no need to elevate the feet unless another medical condition warrants this action.
The cell membrane has embedded within it a series of peripheral proteins that function in several ways. One of these proteins is known as a receptor site. What does this receptor site do? A)Maintains contact with outside proteins to prevent lysis of the cell wall B)Maintains contact with inside proteins to prevent lysis of the cell wall C)Reacts with specific chemicals inside the cell to stimulate a reaction outside the cell D)Reacts with specific chemicals outside the cell to stimulate a reaction within a cell
Ans:D Feedback: Embedded in the cell membrane are a series of peripheral proteins with several functions. One type of protein located on the cell membrane is known as a receptor site. This protein reacts with specific chemicals outside the cell to stimulate a reaction within a cell. Receptor sites do not prevent lysis of the cell wall nor do they stimulate a reaction outside of the cell.
What drug would the nurse administer orally without the need to question when treating infections caused by Candida albicans? A)Amphotericin B (Abelcet) B)Tolnaftate (Tinactin) C)Griseofulvin (Fulvicin) D)Fluconazole (Diflucan)
Ans:D Feedback: Fluconazole is available for oral use and is effective in treating C. albicans. Amphotericin B is reserved for severe and potentially fatal infections, so it would not be used for a C. albicansinfection. Tolnaftate is used to treat athlete's foot and is applied topically, not given orally. Griseofulvin is applied topically and is used to treat tinea, not C. albicans.
A patient is receiving isosorbide dinitrate [Isordil] 20 mg 3 times per day for management of newly diagnosed stable angina. Which assessment finding would require an immediate nursing intervention?
An increase in the resting heart rate to 110 beats/min from baseline rates of 72 beats/min Because nitrates lower blood pressure, isosorbide dinitrate [Isordil] can activate the baroreceptor reflex, causing sympathetic stimulation of the heart; this negates the benefits of treatment with nitrates, because it increases the cardiac oxygen demand. For these reasons, addressing the tachycardia becomes the nurse's immediate priority. A decrease in blood pressure would be expected, and there is no indication the patient is experiencing side effects of decreased cardiac output. Headache is an adverse effect and should be treated (eg, with acetaminophen [Tylenol]), but it does not require immediate intervention. Increased frequency of urination requires follow-up, but it is not the immediate concern.
The nurse is preparing to administer a daily dose of digoxin [Lanoxin]. What is the priority nursing intervention?
Analyze heart rate and rhythm
The nurse is preparing to administer a daily dose of digoxin [Lanoxin]. What is the priority nursing intervention?
Analyze heart rate and rhythm. Before giving digoxin [Lanoxin], the nurse should assess heart rate and rhythm. The dosage will be held and the prescriber notified if the heart rate is below 60 beats/min or if the cardiac rhythm has changed. Digoxin [Lanoxin] can cause bradycardia and electrical changes in the heart.
What are the common adverse effects of the antiviral drug ribavirin? Select all that apply. 1 Anemia 2 Conjunctivitis 3 Peripheral neuropathy 4 Orthostatic hypotension 5 Bone marrow suppression
Anemia Conjunctivitis
A nurse administering flecainide to a patient with sustained ventricular tachycardia will monitor the patient for which adverse drug effect?
Angioedema
The nurse is instructing a patient about potential adverse effects of a prescribed angiotensin-converting enzyme (ACE) inhibitor. For which adverse effect should the patient seek immediate medical attention?
Angioedema Angioedema is a potentially fatal reaction that develops in up to 1% of patients. A dry, nonproductive cough is an adverse reaction but is not life-threatening. If fatigue does occur, it is not life-threatening. Diarrhea is not an adverse effect.
What therapeutic effect will the nurse assess for in the male patient taking anabolic steroids? A)Thinning of the skin B)Body hair loss C)Increase in red blood cells (RBCs) and hemoglobin D)Gynecomastia
Ans C: Feedback: Therapeutic effects include promotion of body tissue-building processes, reverse catabolic or tissue-destroying processes, and increased hemoglobin and red blood cell mass. Thinning of the skin and body hair loss are not associated effects of anabolic steroids. Gynecomastia is an adverse effect and would not be a therapeutic effect for which the drug was administered.
The nurse admitted a 25-year-old woman to the unit. What would be the most important thing for the nurse to assess before administering ketoconazole? A)Complete blood count (CBC) and blood glucose B)Eating and sleeping habits C)Height and weightD)Renal and hepatic function
Ans:D Feedback: It would be important for the nurse to know the patient's CBC, blood glucose level, eating and sleeping habits, and height and weight. All of these factors could help determine a specific dosage. However, the most important factor would be the patient's renal and hepatic function because hepatic or renal toxicity could occur quickly if the organs are not functioning properly.
The nurse is caring for four patients. Which patient would the nurse know that clozapine (Clozaril) is contraindicated for? A)17-year-old adolescent B)23-year-old with diabetes insipidus C)32-year-old with osteoarthritis D)45-year-old with bone marrow depression
Ans:DFeedback: Clozapine is associated with bone marrow suppression, a life-threatening decrease in white blood cells. Because of their wide- ranging adverse effects, antipsychotic drugs may cause or aggravate various conditions. They should be used very cautiously in patients with liver damage, coronary artery disease, cerebrovascular disease, Parkinsonism, bone marrow depression, severe hypotension or hypertension, coma, or severely depressed states. Options A, B, and C are incorrect.
The nurse is caring for a patient who is receiving pancuronium (Pavulon) to facilitate mechanical ventilation. The patient is also receiving a barbiturate. How will the nurse administer these two medications? A)They can be mixed and given in the same syringe. B)Administer IM quickly after mixing the two drugs. C)Shake vigorously when mixed in one syringe. D)If given together, a precipitate may form.
Ans:DFeedback: Do not mix this drug with any alkaline solutions such as barbiturates because a precipitate may form, making it inappropriate for use. Pancuronium is only given IV. Shaking does not prevent precipitation.
While caring for a diabetic patient, the nurse explains that normally insulin is produced by the pancreas and does what when reacting with the human cell? A)Metabolizes glucose B)Allows water to enter the cell C)Alters cellular messenger ribonucleic acid (RNA) D)Changes the cell permeability to glucose
Ans:DFeedback: Insulin reacts with specific receptor sites on the cell membrane to change the cell's permeability to glucose to allow glucose to enter the cell. It does not affect water transport or messenger RNA. Insulin does not metabolize glucose but rather helps it move into the cell where it supplies energy for cellular activity.
Melanocyte-stimulating hormone (MSH) released from the anterior pituitary is important in humans because of its suspected ability to do what? A)Block the perception of pain B)Change the color of skin in some environments C)Stimulate fat mobilizationD)Stimulate nerve growth and development
Ans:DFeedback: MSH might be important for nerve growth and development in humans. Animals use MSH to change skin color as part of protective camouflage, but it does not have this effect in humans. Lipotropins stimulate fat mobilization. Endorphins and enkephalins are hormones that block the perception of pain.
A nurse is teaching a young mother about administering pyrantel (Pin-Rid, others) to her 5-year-old child. What will the nurse emphasize about how the agent is given? A)In 3 doses as a 1-day treatment B)In a morning dose and an evening dose for 3 days C)B.I.D. for 10 days D)Give only once
Ans:DFeedback: Pyrantel is administered orally as a single dose. Albendazole is prescribed for hydatid disease and is given twice a day for 8 to 30 days of treatment. Mebendazole is used in the treatment of diseases caused by pinworms, roundworms, whipworms, and hookworms and is given in a morning and evening dose for 3 days. Praziquantel is used to treat schistosomes and is taken in three doses as a 1-day treatment.
Two types of ribosomes exist within a cell. Ribosomes that are not bound to the endoplasmic reticulum exist throughout the cytoplasm of the cell and produce proteins with what purpose? A)Bind themselves to the Golgi apparatus B)Bind to produce the endoplasmic reticulum C)Denature unnecessary enzymes within the cell D)Contribute to the structure of the cell
Ans:DFeedback: Ribosomes that are not bound to the surface of the endoplasmic reticulum exist throughout the cytoplasm. These free-floating ribosomes produce proteins that are important to the structure of the cell and some of the enzymes that are necessary for cellular activity. Free- floating ribosomes do not bind themselves to Golgi apparatus; produce endoplasmic reticulum; or denature any part of the cell or its contents.
A 22-year-old female is diagnosed with mycobacterial tuberculosis. The physician orders rifampin (Rifadin) 600 mg PO daily. What should the nurse question the patient about? A)Her dietB)Sun exposureC)Type of exercise she does D)Use of contact lenses
Ans:DFeedback: Some antimycobacterial drugs can cause discoloration of body fluids. The orange tinged discoloration can cause permanent stain to contact lenses. The patient should avoid wearing them while on the antimycobacterial therapy. With antimycobacterial drugs there is not a concern is warranted about photosensitivity or exercise. However, due to the GI adverse effects, the nurse may want to discuss an appropriate diet if the patient experiences GI upset after beginning treatment.
A 12-year-old patient with a complicated skin infection has been admitted to the pediatric unit. The physician has ordered Ertapenem (Invanz). What is the nursing priority? A)Transcribe the order to the medication administration record (MAR). B)Perform hand hygiene before preparing the medication. C)Assess the patient's renal and hepatic functions. D)Question the order by calling the physician who prescribed it.
Ans:D Feedback: The nurse should call the physician and question the order Because this drug is not recommended for children younger than 18 years of age. Following clarification of the order, the drug would be transcribed and listed in the MAR. The nurse would then wash her hands before preparing the drug for administration. Assessment of renal and hepatic function is good practice before administering any medication but is not the nursing priority.
In what age group are adrenergic agonists contraindicated? A)Older adults B)Adolescents C)Children D)No age group
Ans:D Feedback: The use of adrenergic agonists varies from ophthalmic preparations for dilating pupils to systemic preparations used to support patients experiencing shock. They are used in patients of all ages. Therefore, the other options are incorrect responses.
The nurse alerts the patient to what adverse effect of tizanidine (Zanaflex) that could cause injury? A)Constipation B)Dry mouth C)Fatigue D)Hypotension
Ans:D Feedback: Tizanidine has been associated with hypotension, which could be a safety risk especially if the patient is also taking an antihypertensive drug. Constipation, dry mouth, and fatigue are common adverse effects that do not pose a safety risk.
A patient presents at the emergency department with respiratory depression and excessive sedation. The family tells the nurse that the patient has been taking medication throughout the evening and gives the nurse an almost empty bottle of benzodiazepines. What other adverse effects would the nurse assess this patient for? A)Seizures B)Tachycardia C)Headache D)Coma
Ans:D Feedback: Toxic effects of benzodiazepines include excessive sedation, respiratory depression, and coma. Flumazenil (Anexate) is a specific antidote that competes with benzodiazepines for benzodiazepine receptors and reverses toxicity. Seizures, tachycardia, and headache would not normally be associated with benzodiazepine toxicity.
What anthelmintics would the nurse expect will be readily absorbed from the gastrointestinal (GI) tract? (Select all that apply.) A)Mebendazole B)Pyrantel C)Albendazole D)Praziquantel E)Ivermectin
Ans:D, E Feedback: Praziquantel and ivermectin are readily absorbed from the GI tract. Mebendazole, pyrantel, and albendazole are not.
The nurse is caring for an African American patient who received a kidney transplant and receives methylprednisolone for immunosuppression. What is the nurse's priority assessment specific to this patient? A)Assessing capillary refill time B)Assessing cardiac rhythm C)Assessing white blood cell count D)Assessing blood glucose levels
Ans: DFeedback: African Americans develop increased toxicity to the corticosteroid methylprednisolone— particularly when it is used for immunosuppression after renal transplantation. This toxicity can include severe steroid-induced diabetes mellitus. A priority intervention with this patient is monitoring blood glucose levels. Assessment of capillary refill time and cardiac rhythm would not be indicated by the data supplied about this patient. White blood cell counts should be monitored on any patient receiving long-term corticosteroids but is not specific to this patient.
A female athlete is using high doses of anabolic steroids to enhance her performance. The nurse warns this patient that such use of anabolic steroids is likely to result in what? A)Masculinization B)Immobility of joints C)Obesity D)Hypotension
Ans: A Feedback: Adverse effects in women include masculinization effects, hirsutism, and deepening of the voice. A woman using anabolic steroids would not expect it to result in joint immobility, obesity, or hypotension.
A patient with heart failure has developed a cough while taking an angiotensin-converting enzyme (ACE) inhibitor. The health care provider discontinued the ACE inhibitor and prescribed an angiotensin II receptor blocker (ARB) as an alternative to the ACE inhibitor. The patient continues to have symptoms of heart failure despite using an ARB. Which medication should the nurse anticipate will be prescribed?
BiDil [Isosorbide Dinitrate and Hydralazine]
The nurse is administering captopril to a patient with heart failure. Which best describes the effects of this drug?
Blocks production of angiotensin II Captopril an angiotensin-converting enzyme (ACE) inhibitor, blocks production of angiotensin II, decreases release of aldosterone, and suppresses degradation of kinins. By suppressing production of angiotensin II, ACE inhibitors cause dilation of arterioles and veins.
Which statement is an accurate description of the mechanism of action for verapamil?
Blocks the slow influx of calcium ions into slow calcium channels
Which description regarding the action of methimazole, a drug prescribed for hyperthyroidism, is accurate? Increases the basal metabolic rate Increases thyroid hormones production Blocks thyroid hormone synthesis Slows heart rate through the sinoatrial (SA) node
Blocks thyroid hormone synthesis
Which phrase describes the action of propylthiouracil (PTU) when prescribed for hyperthyroidism? Decreases metabolism by increasing cellular sensitivity to thyroxine Blocks thyroxine conversion to triiodothyronine (T3) in peripheral tissues Inhibits synthesis of thyroid hormone by blocking iodine uptake Reduces production of thyroid stimulating hormone (TSH) from the pituitary
Blocks thyroxine conversion to triiodothyronine (T3) in peripheral tissues
Which assessment finding is most important for the nurse to obtain before administering hydralazine [Apresoline]?
Blood Pressure Hydralazine [Apresoline] is a vasodilator that causes arteriolar dilation, decreased resistance, and decreased blood pressure. Monitoring of the blood pressure and heart rate is the highest assessment priority.
The nurse administers candesartan [Atacand] to a patient. Which assessment finding should the nurse use as a clinical indicator of the therapeutic effectiveness of the medication?
Blood pressure reduction All angiotensin receptor blockers (ARBs), such as candesartan [Atacand], are approved for hypertension. Reduction in blood pressure equals those seen with angiotensin-converting enzyme (ACE) inhibitors. ARBs will decrease pulmonary congestion. Because ARBs promote vasodilation, the nurse expects the patient's extremities to be warm and pink from increased perfusion. In contrast to ACE inhibitors, ARBs do not cause clinically significant hyperkalemia.
A continuous infusion of sodium nitroprusside has been stopped. Which effect on the patient's blood pressure would the nurse anticipate?
Blood pressure will increase. The nurse would anticipate the patient's blood pressure to increase to pretreatment levels within minutes when a sodium nitroprusside infusion is stopped due to the total duration and half-life of the drug.
The nurse is caring for a patient taking foscarnet. What will the nurse monitor to identify potential side effects of this medication? 1 Platelets 2 Stool guaiac 3 Hemoglobin and hematocrit 4 Blood urea nitrogen and creatinine
Blood urea nitrogen and creatinine
A patient with a ventricular dysrhythmia is to receive lidocaine. The health care provider prescribes a lidocaine bolus at 250 mg, which may be repeated in 5 minutes. This is to be followed by a maintenance lidocaine drip at 2 mg/minute for 24 hours. For which part of the prescription will the nurse require clarification?
Bolus dose of 250 mg The bolus dose should be between 50 to 100 mg. This dose can be repeated in 5 minutes. 250 mg is too high for a single dose.
A patient receives isophane suspension, also known as neutral protamine Hagedorn insulin at 8:00 AM. The patient eats breakfast at 8:30 AM, lunch at noon, and dinner at 6:00 PM. At what time is this patient at the highest risk for hypoglycemia?
Breakfast eaten at 8:30 AM would cover the onset of isophane insulin suspension, also known as neutral protamine Hagedorn, and lunch will cover the 2:00 PM time frame. If the patient does not eat a midafternoon snack, however, the neutral protamine Hagedorn insulin may peak just before dinner without sufficient glucose on hand to prevent hypoglycemia.
amphotericin B (abelcet)
Broad spectrum antifungal Only given by IV route Nephrotoxic -- reversible kidney damage in 80% -- Stop or lower dose if Cr >3.5 -- Give lots of fluids, 500mL fluid over 2 hrs, then give tylenol, benadryl (counteract pro-inflammatory rx), given through central line over 4 hours - not compatible with NS - flush lines with dextrose Electrolyte imbalance -- Low K and Mg -- low potassium levels affect the heart Anemia - may need blood transfusion Administration: -- phlebitis, (use central lines b/c have to give a long time) -- fever/chills -- If get Rigers (uncontrollable shakes) - give demerol then potassium and magnesium. Now comes in lipid formulas which are more expensive but have less side effects
The nursing instructor is talking with her class of students about the female reproductive system. A student is trying to understand the role of progesterone in the body. What nonreproductive affect does progesterone have on the body? A)Decreased body temperature B)Decreased appetite C)Anti-insulinD)Increased uterine motility
C Feedback: Progesterone has an anti-insulin effect to generate a higher blood glucose concentration to allow for rapid diffusion of glucose to the developing embryo. Body temperature and appetite are increased by progesterone. Uterine motility is decreased to provide increased chance that implantation can occur.
Ms. Jones reports episodes of joint and muscle pain to the nurse. What would the nurse's priority action be?
Call the health care provider and request a prescription for an antinuclear antibody (ANA) panel. Given the history of treatment with hydralazine, it is important to complete an ANA panel to evaluate for the adverse effect of systemic lupus erythematosus-like syndrome.
The nurse is caring for a patient who is receiving enteral feedings because of dysphagia. The healthcare provider prescribes isosorbide mononitrate [Imdur] 60 mg SR daily via the enteral tube. What is the most appropriate action by the nurse?
Call the healthcare provider about an alternate form of nitrate for administration. The nurse should contact the prescriber for an alternate form of nitrate, such as a non-sustained-release pill, transdermal patch, topical ointment, or immediate release. Because isosorbide mononitrate [Imdur] is a sustained-release pill, it cannot be crushed. Because the patient has dysphagia, attempting to administer the pill orally could result in aspiration. Sustained-release tablets must be administered whole.
trichinosis
Caused by Trichinella worm. The life cycle spent entirely within the body of a mammalian host. Humans can contract the parasite by eating raw or inadequately cooked pork or bear meat; the cyst envelope is digested in the stomach and small intestine, and larvae are liberated. Final development occurs when the coiled larvae are encysted in the skeletal muscle. Symptoms may be unnoticeable or extreme depending on how many larvae were ingested. Drugs of choice: albendazole, and prednisone
The nurse is caring for a patient receiving hydralazine [Apresoline]. The healthcare provider prescribes propranolol [Inderal]. The nurse knows that a drug such as propranolol often is combined with hydralazine for what purpose? A. To reduce the risk of headache B. To improve hypotensive effects C. To prevent heart failure D. To protect against reflex tachycardia
D. To protect against reflex tachycardia Hydralazine is a vasodilator that lowers blood pressure, but it also can trigger reflex tachycardia. Beta blockers, such as propranolol, are added to the regimen to normalize the heart rate.
A patient who has been taking warfarin for chronic atrial fibrillation was advised by a friend to consume a low-protein diet. Which change in warfarin dosage would the nurse anticipate?
Decrease
Which phrase describes the goal of cinacalcet drug therapy? Increase calcium absorption and blood levels. Decrease parathyroid hormone (PTH) production in the body. Activate vitamin D for the body's use. Decrease and normalize calcium levels.
Decrease and normalize calcium levels
A patient is prescribed lisinopril [Prinivil] 40 mg by mouth once a day for hypertension. For which therapeutic effect should the nurse monitor?
Decrease in blood pressure The therapeutic effect of angiotensin-converting enzyme (ACE) inhibitors is to reduce blood pressure in patients with hypertension. ACE inhibitors do not affect patients' heart rate. Dizziness and fainting are symptoms of hypotension. ACE inhibitors do not affect oxygen saturation.
A patient is prescribed to receive an initial dose of amiodarone 800 mg and a maintenance dose of warfarin 8 mg. Which action would the nurse expect when notifying the health care provider about the order?
Decrease the dose of warfarin.
A patient is prescribed to receive an initial dose of amiodarone 800 mg and a maintenance dose of warfarin 8 mg. Which action would the nurse expect when notifying the health care provider about the order?
Decrease the dose of warfarin. Amiodarone can increase the level of warfarin. The dose of warfarin may need to be decreased.
The patient with which medical condition will most likely benefit from lidocaine administered intravenously?
Decreased heart rate Quinidine, a Class IA antidysrhythmic drug, slows the conduction rate and prolongs repolarization, which decreases heart rate such as in atrial fibrillation with rapid ventricular response. Decreasing heart rate is a therapeutic effect. However, the nurse will need to monitor for heart rate less than 60 beats/minute, indicating bradycardia, which is a side effect of quinidine.
TMP SMX
Decreased resistance to permethrin has occurred when administered with _____/_____ (kill bacteria in lice used to make B vit they need to live)
Which phrase describes the action of cinacalcet when prescribed to balance calcium levels in the body? Elevates parathyroid hormone (PTH) levels and increases calcium absorption from the intestines Decreases PTH by increasing calcium receptor sensitivity in the body Activates vitamin D, which is needed for PTH production and absorption of calcium Enhances the production of parathyroid hormones, which stimulate kidney excretion of calcium
Decreases PTH by increasing calcium receptor sensitivity in the body
A patient is being treated with digoxin for atrial fibrillation. Which finding would concern the nurse?
Development of second-degree block Digoxin prolongs the PR interval as a result of the slowed atrioventricular (AV) conduction. Development of second-degree block is a contraindication for digoxin.
Digoxin
Digoxin is primarily used for heart failure. Digoxin can also be used for atrial fibrillation/flutter and PSVT. Digoxin is not effective against ventricular dysrhythmias, such as supraventricular tachycardia/fibrillation.
Subsequent Dosing Assessment for digoxin
Digoxin levels must be closely monitored due to the narrow range between therapeutic and toxic levels. Assess apical pulse for 1 minute. If 60 beats/min or less, withhold drug and contact health care provider. Digoxin levels should be evaluated 6 to 8 hours after administration or just before the next dose. Therapeutic serum level: 0.8 to 2 ng/mL; toxic serum level: greater than 2 ng/mL.
Extra caution must be taken when patients take Class IV antidysrhythmic drugs and digoxin, concurrently
Digoxin suppresses impulse conduction through the AV node, thereby increasing the risk of AV block. Patients receiving both Class IV antidysrhythmic drugs and digoxin should be monitored closely. Class IV antidysrhythmic drugs increase plasma levels of digoxin by about 60%, which increases the risk of digoxin toxicity.
The nurse is teaching about nondihydropyridine calcium channel blockers. Which medication would the nurse include?
Diltiazem
Which inhibitory neurotransmitter is involved in Parkinson's disease (PD)?
Dopamine is the inhibitory neurotransmitter involved in PD. The disease is characterized by low concentrations of dopamine. Acetylcholine is an excitatory neurotransmitter that counteracts the effects of dopamine. The adrenergic glands on the kidney release adrenaline. Oxytocin is released by the pituitary gland; it is a not a neurotransmitter.
Which phrase indicates therapeutic effectiveness of cinacalcet prescribed for hyperparathyroidism? Slowing progression of osteoporosis Increasing parathyroid hormone level Diminishing muscle spasm and twitching Down trending of calcium blood levels toward normal
Down trending of calcium blood levels toward normal
The nurse is completing discharge teaching, Which includes the direction, "Do not stop the angiotensin-converting enzyme (ACE) inhibitor abruptly" Which effect would the nurse tell the patient to expect if the medication were stopped suddenly?
Dramatic increase in BP ( The patient's blood pressure can rebound and become very hypertensive if the medication is stopped abruptly. This is called rebound hypertension)
The nurse is completing discharge teaching, which includes the direction, "Do not stop the angiotensin-converting enzyme (ACE) inhibitor abruptly." Which effect would the nurse tell the patient to expect if the medication were stopped suddenly?
Dramatic increase in blood pressure
threadworm
Drug of choice for _______ infestation: - ivermectin - Inhabit small intestine, can be very dangerous - common in southern U.S.
mebendazole
Drug of choice for helminthiasis: _____________ Most intestinal roundworms Prevents uptake of glucose by susceptible intestinal worms, which causes slow death (doesn't affect our glucose levels, however) Poorly absorbed, remains in gut, plasma levels remain low Avoid in 1st trimester d/t limited data ** may take up to 3 days for parasite to be cleared d/t slow death
permethrin
Drug of choice for scabies = ________ - 1 dose of ivermectin is also effective but not approved by FDA - other drugs: crotamiton, malathion, lindane ** Intense itching occurs for a week or 2 after SUCCESSFUL TX - educate!
The nurse is caring for a patient undergoing chemotherapy for breast cancer. Which should the nurse recognize as the rationale for using more than one chemotherapy drug simultaneously?
Drug resistance occurs less frequently.
permethrin, malathion
Drugs for body lice: ________ and ________ If these topical tx fail, oral ivermectin may be used
giant roundworm
Drugs of choice for ______ _______ infestation: - albendazole, mebendazole, ivermectin
pinworm
Drugs of choice for ______ infestation: - albendazole, mebendazole, pyrantel pamoate * sx: perianal itching * entire household should be treated at same time
hookworm
Drugs of choice for _______ infestation: - albendazole, mebendazole, pyrantel pamoate - Nausea, vomiting and abd pain may occur with infestation - Attach to wall of small intestine and suck blood
3 (Schistosomiasis (a blood fluke infestation) has acute and chronic phases. In the chronic phase, the infestation predominates in the vascular system, producing portal hypertension and hepatosplenomegaly. Pruritic dermatitis and vision disturbances are findings seen in onchocerciasis (river blindness). Bowel obstruction is seen in fasciolopsiasis (intestinal fluke infestation).)
During the chronic phase of infestation with schistosomiasis, it is most important for the nurse to monitor the patient for what? 1 Pruritic dermatitis 2 Vision disturbances 3 Hepatosplenomegaly 4 Bowel obstruction
The nurse should be on heightened alert for the signs and symptoms of digoxin toxicity.
During the first 1 to 2 hours after administration, assess apical pulse for bradycardia and ECG or cardiac monitor for dysrhythmias (excessive slowing of pulse may be first clinical sign of toxicity). During loading dose, assess for signs of toxicity (GI disturbances and neurologic abnormalities). Monitor serum potassium, magnesium, calcium, and renal function. Assess for signs and symptoms of digitalis toxicity (anorexia, nausea, vomiting, bradycardia, cardiac dysrhythmias, and visual disturbances). Report symptoms immediately to the health care provider.
A patient scheduled for surgery is to have a nondepolarizing neuromuscular junction (NMJ) blocker as adjunctive anesthesia. The nurse will have cause for concern about prolonged paralysis if the patient has been taking what medication? A)An aminoglycoside B)AminophyllineC)A barbiturate anesthetic D)A cephalosporin
Feedback: Combining nondepolarizing NMJ blockers with aminoglycosides can result in prolonged paralysis, and this combination should be avoided. This interaction does not occur with barbiturate anesthetics, cephalosporins, or aminophylline.
The home health nurse provides patient teaching to his or her patient who is taking oral prednisolone. The nurse provides what instruction to reduce the occurrence of nausea? A)"Take with a meal."B)"Take 1 hour before meals."C)"Take before bedtime."D)"Split the dose into two equal doses."
Feedback: Steroids, taken on an empty stomach, would exacerbate the nausea. If the patient takes only one dose per day, it should be taken immediately after breakfast. If spaced throughout the day, eating something before taking the pill will reduce risk of nausea. Timing is dictated by frequency of administration, and if only taken once daily, the medication should be taken in the morning (so bedtime is inappropriate). Splitting the dose would decrease effectiveness and would be inappropriate for the nurse to suggest because it is outside the scope of nursing practice. Taking the medication before meals would mean it was being taken on an empty stomach.
The adrenal cortex responds to adrenocorticotropic hormone (ACTH), which responds to corticotropin-releasing hormone (CRH) from the hypothalamus in a daily pattern called what? A)Pituitary rhythm B)hypothalamic-pituitary axis C)Diurnal rhythm D)Circadian rhythm
Feedback: The adrenal cortex responds to ACTH released from the anterior pituitary. ACTH, in turn, responds to CRH released from the hypothalamus. This happens regularly during a normal day in what is called "diurnal rhythm." Pituitary rhythm is a distracter; the term does not exist. The hypothalamic- pituitary axis involves the interaction between the two glands. Circadian rhythm involves when people prefer to be most active, such as people who say they are "morning people."
A patient with ventricular tachycardia and a pulse is to receive lidocaine. Before administering lidocaine the nurse will assess for which contraindications to lidocaine?
First-degree atrioventricular block Second-degree Mobitz I atrioventricular block Wolff-Parkinson-White (WPW) syndrome

Class IV Antidysrhythmic Drugs determine baseline data
For all patients a thorough history and physical assessment should be conducted. History includes use of pharmacologic and nonpharmacologic therapies. Additionally, the nurse should evaluate the blood pressure and pulse rate and assess liver and kidney function by reviewing relevant laboratory data. Obtain a baseline ECG to compare periodically during the treatment. Obtain baseline weight.
The nurse is teaching the patient how to administer insulin. What information is essential to include in the plan? For the most consistent absorption, inject the insulin into the abdomen." "Avoid administering the insulin into your arm." "Inject the insulin at a 30-degree angle between the fat and muscle." "Do not mix any insulins in the same syringe."
For the most consistent absorption, inject the insulin into the abdomen." The abdomen has the most consistent absorption because the blood flow to the subcutaneous tissue typically is not as affected by muscular movements as it could be in the arm or thigh. Insulin can be administered in the arm. The patient should be instructed to inject insulin at a 45- to 90-degree angle, not a 30-degree angle. Most insulins can be mixed.

Frequent sites of helminth infestation occur in which areas of the body? (Select all that apply.) 1 Intestine 2 Lymphatic system 3 Brain 4 Blood vessels 5 Liver
The nurse is caring for a patient who has congestive heart failure. The patient's medical history indicates that the patient has a history of chronic kidney disease with a low glomerular filtration rate. Which drug would the nurse anticipate to be prescribed for the patient?
Furosemide [Lasix] Furosemide [Lasix] is especially useful in patients with severe renal impairment, since, unlike the thiazides, the drug can promote diuresis even when renal blood flow and glomerular filtration rate (GFR) are low. The use of thiazides (metolazone or hydrochlorothiazide or methyclothiazide) is not effective with a low GFR.
The nurse is administering several different diuretics. Which drug will produce the most diuresis in a patient?
Furosemide [Lasix] Furosemide [Lasix] is the most potent diuretic. Drugs that act early in the nephron have the opportunity to block the greatest amount of solute reabsorption. Furosemide [Lasix] works at the loop of Henle; as a result, furosemide [Lasix] produces the greatest diuresis. Hydrochlorothiazide [Microzide] works on the early distal convoluted tubule so does not have the capacity to excrete as much sodium and water as a loop diuretic and is less effective. Triamterene [Dyrenium] and spironolactone [Aldactone] work at the distal nephron so do not have the ability to excrete as much sodium and water as loop diuretics.
A patient who has been taking digoxin for several months is now complaining about changes to vision. Which action would the nurse take?
Further inquire about the vision changes.
A patient who has been taking digoxin for several months is now complaining about changes to vision. Which action would the nurse take?

Which statement accurately describes corticosteroids?
Glucocorticoids affect carbohydrate metabolism, and mineralocorticoids regulate electrolytes.
Which laboratory test would give the most accurate evidence of a diabetic patient's treatment compliance and glucose management over the past few months?
Glycosylated hemoglobin (HbA1c) HbA1c indicates glucose concentrations over the past 3 to 4 months and thus demonstrates patient compliance and illness management over time. The serum albumin test helps to determine the level of natural protein in blood. The fasting serum glucose test helps to assess whether the patient has elevated blood glucose concentrations. A 2-hour postprandial blood glucose test determines the amount of glucose in the blood after a meal.
When teaching a patient about amiodarone, the nurse should advise the patient to avoid which food or drink?
Grapefruit juice Grapefruit juice can inhibit the metabolism of several antidysrhythmics, such as amiodarone, disopyramide, and quinidine. It is not necessary to restrict gluten, poultry, and whole milk from the patient's diet.
Which statement is accurate regarding the interaction between verapamil and grapefruit juice?
Grapefruit juice can inhibit the metabolism of verapamil.

A health care provider prescribes diltiazem 10 mg intravenous push for persistent atrial fibrillation with a ventricular rate of 115 beats/min. While preparing the diltiazem, the nurse notices the patient is on digoxin 0.125 mg and metoprolol 25 mg. Which action will the nurse take?
Hold the diltiazem. The nurse would hold the diltiazem until the prescription can be clarified with the health care provider. Giving diltiazem to a patient who is already taking digoxin and metoprolol could suppress the cardiac function and cause severe bradycardia, decrease atrioventricular conduction, and decrease cardiac contractility. Beta blockers and diltiazem should be administered several hours apart to minimize the risk of cardiosuppression.
Before administering diltiazem, the nurse observes the patient's pulse at 54 beats/min on the cardiac monitor. Which action will the nurse take next?
Hold the drug

Ibuprofen, a nonsteroidal antiinflammatory drug, for pain Metformin, an antidiabetic drug Furosemide, a loop diuretic
Before administering adenosine, the nurse should do the following:
Identify the dysrhythmia. Assess apical pulse and blood pressure. Determine whether specific symptoms are present and whether the symptoms are related to tachydysrhythmias.Assess the patient's symptoms.Determine whether the patient is stable.Determine whether the rhythm is regular or irregular.Assess whether the QRS complex is narrow or wide.Determine whether the patient is in sinus tachycardia, supraventricular tachycardia, or atrial fibrillation with rapid ventricular response (RVR). Assess for altered mental status, continuing chest pain, hypotension, or other signs of shock.
Which teaching points would a nurse share with a patient newly prescribed the ethinyl estradiol plus etonogestrel vaginal ring (NuvaRing®) who has never received hormonal contraception before?
If it is expelled during treatment weeks, it may be washed off with warm water and reinserted. She should vaginally insert the ring between day 1 and day 5 of the menstrual cycle, even if she is bleeding. The ring should be replaced every 3 weeks, removing for 1 week at the end of this time frame before inserting a new one. If the ring is expelled for more than 3 hours during week 1 or 2 of use, she should reinsert the ring and use backup contraception for 7 days.
A patient with Addison's disease is upset about weight gain and wants to stop taking hydrocortisone and fludrocortisone. Which response would the nurse make? "Weight gain is a side effect of the medication. You may need to seek counseling." "It is fine to stop taking your medicine as long as you carefully monitor your glucose levels." "If you stop taking the medications, you may have severe side effects." "Begin to taper your dosage and check with your health care provider about an exercise program that you can begin."
If you stop taking the medications, you may have severe side effects
A nurse is caring for a patient who has been prescribed clomiphene citrate for infertility. The patient also takes methyldopa for hypertension. Which outcome would a nurse anticipate may come from the drug interaction between methyldopa and clomiphene citrate?
Impaired fertility due to an increase in prolactin
A child has an infestation of scabies. Which area should the nurse assess first when evaluating for improvement of the condition?

Which is the most appropriate action for the nurse who is told that a patient typically takes his glipizide (Glucotrol) with food? Immediately check the patient's blood glucose level. Inform the patient that it is better to take the medication 30 minutes before a meal. Inform the patient that the medication must be taken 15 minutes after a meal. Immediately call the health care provider.
Inform the patient that it is better to take the medication 30 minutes before a meal. Food inhibits the absorption of glipizide (Glucotrol), the only sulfonylurea agent that should be given 30 minutes before a meal. The blood glucose level does not have to be taken right away. The medication is not to be taken after a meal. The health care provider does not have to be called; the nurse should intervene.
A patient receiving the adrenergic medication clonidine [Catapres] reports experiencing dry mouth. What should be included in the plan of care for this patient?
Inform the patient that these are common adverse effects of the medication. Dry mouth is one of the most common adverse effects of adrenergic medications such as clonidine so the patient should be made aware of this. Restricting dietary fiber intake, limiting fluids, and incorporating a psyllium-based product in the patient's diet will not help with the complaint of dry mouth.
A patient who is treated with zidovudine develops blistering rashes, fever, and myalgia. What should the nurse do first? 1 Ask the patient to take bed rest. 2 Administer antipyretic medications. 3 Administer antihistamine medications. 4 Inform the primary health care provider.

D.You should take 325 mg of aspirin a half hour before each dose of Niacin to prevent this effect
D
The nurse is working in the emergency department when a patient with a head injury develops increased intracranial pressure. Which drug would the nurse anticipate administering?
Mannitol [Osmitrol] Intracranial pressure (ICP) that has been elevated by cerebral edema can be reduced with mannitol [Osmitrol]. The drug lowers ICP because its presence in the blood vessels of the brain creates an osmotic force that draws edematous fluid from the brain into the blood. Metolazone [Zaroxolyn] and hydrochlorothiazide [Microzide] are thiazide-like diuretics; spironolactone [Aldactone] is a potassium-sparing diuretic; they are of little benefit in reducing cerebral edema.
A patient of Asian descent was prescribed chloroquine. Which action by the nurse would be appropriate?
Many Asian persons have increased risk of ocular disease while taking chloroquine

Which hormonal contraceptive has the longest elimination half-life?
Medroxyprogesterone acetate injection (Depo Provera®)
The nurse has just administered the initial dose of enalapril [Vasotec] to a newly admitted patient with hypertension. What is the priority nursing intervention over the next several hours?
Monitor blood pressure. First-dose hypotension is a serious potential adverse effect of angiotensin-converting enzyme (ACE) inhibitors such as enalapril [Vasotec]. Monitoring the blood pressure is the priority nursing intervention. If hypotension develops, the nurse will place the patient in the supine position and possibly increase intravenous fluids. The other interventions may be appropriate for this patient; however, in the hours immediately after the first dose of an ACE inhibitor, monitoring of the blood pressure is most important.
The healthcare provider prescribes an intravenous dose of diltiazem [Cardizem] for treatment of a patient with atrial fibrillation. What is the priority nursing intervention?
Monitor electrocardiogram. Monitor the electrocardiogram (ECG) continuously during intravenous (IV) administration of diltiazem [Cardizem] for atrioventricular (AV) block, sudden reduction in heart rate, and prolongation of the PR or QT interval. Cardioversion is not necessary; however, the nurse should have equipment for cardioversion available. Baseline laboratory studies are needed for liver and kidney function. Increased urinary output is not an adverse effect of diltiazem [Cardizem].
The nurse is administering intravenous lidocaine [Xylocaine] to a patient with a ventricular dysrhythmia. Which is the priority nursing intervention to prevent a potential complication with this drug?
Monitor the electrocardiogram (ECG). Continuous electrocardiogram (ECG) monitoring is required during lidocaine [Xylocaine] infusions to evaluate cardiac response and adjust dosage accordingly and detect toxicity. Blood counts are not necessary, because lidocaine [Xylocaine] is not linked to blood dyscrasias. Preferably Lidocaine [Xylocaine] is given intravenously (IV) rather than intramuscularly (IM). Sudden onset of chest pain is a sign of arterial embolism, which is a possible adverse effect of quinidine, not lidocaine [Xylocaine]. Naloxone [Narcan] is a reversal agent for opioids and is not used with lidocaine [Xylocaine].
Which classes of drugs are used in the treatment of angina pectoris? Select all that apply.
Nitrates Beta Blockers Calcium Channel Blockers Nitrates and nitrites minimize the frequency of angina attacks by dilating all blood vessels. Beta blockers are effective after a myocardial infarction to minimize the negative effects of catecholamines. Calcium channel blockers help decrease the afterload and reduce the workload of the heart. Diuretics are not prescribed for the treatment of angina pectoris but to increase the patient's fluid output. Antihistamines are used to reduce the physiologic and pharmacologic effects of histamine.
Which value indicates the effectiveness of levothyroxine? Increased heart rate Normal calcium levels Normal thyroid stimulating hormone (TSH) and T4 Decreased respiratory rate
Normal thyroid stimulating hormone (TSH) and T4
Digoxin cardiac system
Note history of dysrhythmias, hypotension, abnormal heart sounds, or abnormal ECG findings.

Notify the health care provider
The health care provider is considering prescribing a patient ritonavir. The patient tells the nurse about recently being diagnosed with type 2 diabetes mellitus. What is the nurse's highest priority action? 1 Instruct the patient to keep an accurate glucose log. 2 Notify the health care provider of the new information. 3 Instruct the patient to monitor blood sugars more often. 4 Notify the pharmacist that a larger dose will be needed.
Notify the health care provider of the new information. - The health care provider should be notified of this new information. Patients with diabetes mellitus or hyperglycemia may experience an exacerbation of their condition during ritonavir treatment.
A patient has been receiving subcutaneous heparin every 12 hours. The patient is scheduled to have a lumbar puncture at 0900. Which action is the nurse's priority?
Notify the health care provider the patient is receiving heparin. The health care provider needs to know when the patient last received heparin. Heparin therapy is contraindicated in patients who will be undergoing a lumbar puncture. The patient is at increased risk for bleeding due to heparin, and hematoma can develop during or after the puncture.
A nurse is preparing to administer clopidogrel and aspirin to a patient who has an altered CYP2C19 gene. Which action would the nurse take?
Notify the health care provider. Nurses would identify high-risk patients for potential complications from drugs. Patients with an altered CYP2C19 gene are poor metabolizers of clopidogrel, which places them at higher risk for complications; therefore the nurse would contact the health care provider to verify the prescription.
The nurse is caring for a patient who is scheduled to begin treatment with carvedilol [Coreg]. While updating the history, the patient tells the nurse that he experiences frequent attacks of asthma. What is the nurse's highest priority action?
Notify the healthcare provider of this information. Carvedilol [Coreg] should be used with caution in patients with a history of asthma. The priority for the nurse is to notify the healthcare provider of this information.
The laboratory calls to report a drop in the platelet count to 90,000/mm3 for a patient receiving heparin for the treatment of postoperative deep vein thrombosis (DVT). Which action by the nurse is the most appropriate?
Notify the healthcare provider to discuss the reduction or withdrawal of heparin. The nurse should notify the healthcare provider to discuss the reduction or withdrawal of heparin. Heparin-induced thrombocytopenia (HIT) is a potential immune-mediated adverse effect of heparin infusions that can prove fatal. HIT is suspected when the platelet counts fall significantly. A platelet count below 100,000/mm3 would warrant discontinuation of the heparin.
A nurse is caring for a patient who is taking an angiotensin-converting enzyme (ACE) inhibitor and develops a dry, nonproductive cough. What is the nurse's priority action?
Notify the healthcare provider. 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 healthcare provide should switch the patient to a different medication if the side effect cannot be tolerated.
Which instruction will be included in the discharge teaching for a patient with a transdermal nitroglycerin patch?
"Apply the patch to a hairless, nonfatty area of the upper torso or arm." A nitroglycerin patch should be applied to a hairless, nonfatty area for the best and most consistent absorption rates. The sites should be rotated to prevent skin irritation. Headache is a brief side effect of the therapy, but it soon diminishes. Nitroglycerin [Nitro-Bid] is administered via the sublingual route to relieve chest pain.
A patient who is being discharged on diltiazem tells the nurse that cooking with herbs and taking supplements has improved the patient's physical stamina. Which response by the nurse is appropriate?
"Certain supplements can alter the therapeutic effects of diltiazem."
The nurse is providing education to a patient who is being discharged on valsartan. Which patient responses indicate that more education is required?
"Which one of those medications is for my blood pressure?" "I have to take it with food or it won't work." "I take it only when my blood pressure is over 180/80 mm Hg."

What should the nurse assess in a patient who is prescribed metformin [Glucophage] for treatment of type 2 diabetes?
Renal function As metformin [Glucophage] is excreted by the kidneys, it is necessary to assess the patient's renal function. If the patient's kidneys are not able to excrete the drug, it will accumulate in the patient's system, thereby causing lactic acidosis. One of the adverse effects of metformin [Glucophage] is weight loss, not weight gain. Headaches are not caused by metformin [Glucophage]. Cholesterol levels may be high in some diabetic patients but can be treated with medications and lifestyle changes.
Place the steps of the renin-angiotensin-aldosterone system (RAAS) in order.
Renin forms angiotensin I. Angiotensin-converting enzyme converts angiotensin I to angiotensin II. Angiotensin II, a potent vasoconstrictor, triggers the adrenal cortex to secrete aldosterone.

Assess for history of headaches, fatigue, confusion, or convulsions. Assess level of alertness and orientation.
A patient is prescribed digoxin to treat heart failure. Which biochemical parameter should be assessed by the nurse to ensure safe drug administration?
Serum potassium concentration Hypokalemia, usually diuretic induced, is the most frequent underlying cause of dysrhythmias. The nurse should monitor serum potassium concentrations. Because potassium competes with digoxin, when potassium levels are low, binding of digoxin to Na+, K+-ATPase (sodium, potassium-ATPase) increases. This increase can produce excessive inhibition of Na+, K+ -ATPase with resultant toxicity. Digoxin does not have any effect on liver enzymes, blood glucose, or serum calcium. Therefore, assessment of these parameters is not necessary before administering digoxin.
The nurse is providing teaching education to a patient who is being discharged with prescriptions for clopidogrel and aspirin. The patient tells the nurse that fresh garlic is used to season many of the foods eaten. Which response would the nurse make?
Avoid garlic - it can increase chance of bleeding

General drug adherence for digoxin
Stress the importance of taking the medication exactly as prescribed. A nurse may visit to ensure that medications are properly taken. Inform the patient of possible food/herbal drug interactions. Due to the many drug interactions that could occur, over-the-counter (OTC) medications should not be taken without approval from the health care provider. Keep drugs out of reach of small children. Childproof bottles should be requested. Take the medication at the same time every day. Take a missed dose if no more than 12 hours have passed from the time the drug was to have been taken. Do not double up on next dose. Contact the health care provider for further instructions. Never abruptly stop taking the medication.
What hormone causes ovulation to occur? A)Adrenocorticotropic hormone (ACTH) B)Luteinizing hormone (LH) C)Prolactin D)Follicle-stimulating hormone (FSH)
B Feedback: When the circulating estrogen level rises high enough, it stimulates a massive release of LH from the anterior pituitary causing one of the developing follicles to burst and release the ovum with its stored hormones into the system. ACTH targets the adrenal corticosteroid hormone, which helps prepare the body for the "fight or flight" response. Prolactin is responsible for milk production and FSH in combination with LH stimulate follicles on the outer surface of the uterus to grow and develop and also stimulates the release of estrogen and progesterone.
The nurse is writing a plan of care for a patient receiving an alpha-specific adrenergic agonist. What should this plan of care include? A)Monitoring the patient for diarrhea B)Monitoring blood pressure and heart rate every 2 to 4 hours C)Assessing skin turgor for dehydration D)Assessing for fatigue and lethargy
B Sympathetic stimulation will cause hypertension and increased heart rate so it is important these be monitored. Sympathetic stimulation will also result in increased sweating, decreased gastrointestinal activity, and a sense of anxiety and heightened awareness. Diarrhea, dehydration, fatigue, and lethargy would not be expected.
The nurse is teaching a patient who has just been prescribed a vasodilator. Which statement by the patient indicates that the teaching was effective? A. "I can take this medication in the morning to reduce nighttime urination." B. "I will rise slowly when changing from a sitting to a standing position." C. "My heart rate may slow down with this drug. I will call if my pulse is below 60." D. "I need to increase my intake of fluids and foods that are high in fiber."
B. "I will rise slowly when changing from a sitting to a standing position." Vasodilators may cause postural hypotension and reflex tachycardia. Patients should be taught to move slowly when changing positions to prevent dizziness.
A patient with type 1 diabetes mellitus asks, "Why can't I take a sulfonylurea like my friend who has diabetes?" What is the nurse's best response?
Sulfonylurea agents reduce serum glucose levels by increasing beta-cell stimulation for insulin release, decreasing hepatic glucose production, and increasing insulin sensitivity. It is administered for type 2 diabetes mellitus but will not be effective in type 1. Not all patients with type 2 diabetes require insulin, but patients with type 1 diabetes require insulin.
The patient with type 1 diabetes mellitus asks, "Why can't I take a sulfonylurea like my friend who has diabetes?" What is the nurse's best response? "Sulfonylurea increases beta-cell stimulation to secrete insulin, and with your type of diabetes, the beta cells do not contain insulin. This medication will not work for you." "You must be mistaken. If your friend has diabetes mellitus, she is taking insulin." "Sulfonylurea will lower your blood sugar too much, and you will be hypoglycemic." "You are unable to store glucose, because you do not have insulin, and sulfonylurea helps with glucose storage."
Sulfonylurea increases beta-cell stimulation to secrete insulin, and with your type of diabetes, the beta cells do not contain insulin. This medication will not work for you." Sulfonylurea agents reduce serum glucose levels by increasing beta-cell stimulation for insulin release, decreasing hepatic glucose production, and increasing insulin sensitivity. It is administered for type 2 diabetes mellitus but will not be effective in type 1.

The nurse is caring for a patient who has been prescribed trimethoprim/sulfamethoxazole (TMP/SMZ). Which complication might the nurse expect to find in the patient?
TMP/SMZ belongs to the sulfonamide class of drugs. It causes the accumulation of potassium levels and may cause hyperkalemia. Therefore, the nurse would expect the patient to have an increase in potassium levels. TMP/SMZ increases the elimination of sodium and may cause hyponatremia. TMP/SMZ may enhance the secretion of insulin and decrease blood glucose levels, resulting in hypoglycemia. TMP/SMZ has antibacterial activity and decreases the white blood cell count.
In the failing heart, arterial pressure falls, stimulating the baroreceptor reflex to increase sympathetic nervous system activity. The nurse understands increased sympathetic activity will produce which response?
Tachycardia Increased sympathetic activity results in an increased heart rate (tachycardia), increased contractility, increased venous tone, and increased arteriolar tone (elevated blood pressure). Sympathetic stimulation also causes bronchodilation (not bradypnea) and possibly hyperglycemia.
Which time of day is best for taking a thyroid replacement drug? Before breakfast After meals With meals At bedtime

Which technique is most appropriate regarding mixing insulin when the patient must administer 30 units regular insulin and 70 units NPH insulin in the morning? Draw up the regular insulin into the syringe first, followed by the cloudy NPH insulin. Draw the medication into two separate syringes but inject into the same spot. Administer these insulins at least 10 minutes apart, so that you will know when they are working. Use the Z-track method for administration.
Draw up the regular insulin into the syringe first, followed by the cloudy NPH insulin. Drawing up the regular insulin into the syringe first prevents accidental mixture of NPH insulin into the vial of regular insulin, which could cause an alteration in the onset of action of the regular insulin. The medications do not have to be in separate syringes and can be administered together. Z-track is an IM technique.
whipworm
Drug of choice for ______ infestation: - albendazole
A (Adenosine must be given as rapidly as possible, followed by a 50-mL normal saline flush in order to get all of the medication into the circulation quickly since the half-life of adenosine is less than 10 seconds.)
The nurse is reviewing emergency protocols and administration of adenosine (Adenocard). What is a vitally important task to remember when administering adenosine? Give it as a rapid intravenous push. Give it at the highest port in the IV tubing. Offer it with food or milk. Prepare to set up for an intravenous drip infusion.
C, D Prednisone (Deltasone), which is a synthetic glucocorticoid, should be administered in the early morning because the adrenal glands secrete the maximum amount of hormones during the early morning. This helps to prevent adrenal suppression. Glucocorticoids can cause gastrointestinal (GI) distress and should be administered with milk or food to minimize GI upset. This medication should not be administered on an empty stomach because it would enhance the effects of gastric irritation. It should not be administered early in the evening because the adrenocortical secretion levels are low during evenings. This drug is ulcerogenic; hence the administration of aspirin and other nonsteroidal anti-inflammatory drugs should be avoided, which otherwise would cause gastric irritation and gastric bleeding.
The nurse is teaching a patient who has been prescribed a daily oral dose of prednisone (Deltasone) about the medication regimen. How will the nurse tell the patient to take this medication to ensure safe administration? Select all that apply. A. Take on an empty stomach B. Take in the early evening C. Take in the early morning D. Take with milk or food E. Take with aspirin

Educate patients to report side effects (e.g., flushing, headaches, and dizziness) to the health care provider. Advise patients to change positions often, but slowly, to prevent orthostatic hypotension. When a patient is taking high doses of a vasodilator, orthostatic hypotension is a common occurrence.
metronidazole (Flagyl)
Effective against several protozoal species Also effective against anaerobic bacteria Given PO or IV - don't give faster than an hour Common AE: nausea, HA, dry mouth, metallic taste, insomnia, vertigo, weakness Rare AE: SJS, encephalopathy, aseptic meningitis Tints urine a darker brown
There are also common foods and herbal supplements that interact with digoxin.
Ephedra may increase the risk of dysrhythmias. Licorice and ginseng can increase digoxin toxicity. St. John's wort can lead to subtherapeutic effects of digoxin. Large amounts of high-fiber foods (bran, pectin) can decrease the absorption of oral digoxin. Digoxin should be administered 1 hour before or 2 hours after a high-fiber meal.
A patient who takes ergotamine for migraines calls the clinic to report numbness in the feet, which are also cold and pale. Which response by the nurse is appropriate?
Ergotamine can cause ischemia due to the constriction of arteries in the limbs. Gangrene can result if treatment is not received immediately. It is not appropriate to tell the patient to wait to seek care until an appointment with the provider or to place the feet in hot water because this may not be effective, and permanent damage may result from the a subsequent delay in treatment. The constriction is not a permanent vascular change, it may be reversed by discontinuing the medication.
Which condition is seen in a patient with hyperosmolar nonketotic syndrome (HHNS)?
Extreme hyperglycemia Extreme hyperglycemia triggers hyperosmolar nonketotic syndrome (HHNS). Acute pancreatitis is an inflammation of the pancreas. This usually happens due to chronic alcohol abuse or due to a gallstone becoming lodged in the pancreatic ducts. Headaches are not caused by HHNS. A patient with HHNS may have electrolyte imbalances, which may cause dehydration and weight loss, not weight gain.
Which patient symptoms should cause the nurse to be concerned about digoxin [Lanoxin] toxicity? (Select all that apply.)
Fatigue Vomiting Blurred vision
The home health nurse is caring for a 77- year-old male patient who has just been discharged from the hospital. The patient is receiving an infusion of dobutamine (Dobutrex) to treat congestive heart failure. What is the priority nursing assessment? A)Capillary refill time and vital signs B)Effectiveness of comfort measures C)Dietary intake and hydration D)Compliance with treatment plan
Feedback: Dobutamine, although it acts at both receptor sites, has a slight preference for beta1- receptor sites. It is used in the treatment of heart failure because it can increase myocardial contractility without much change in rate and does not increase the oxygen demand of the cardiac muscle, an advantage over all of the other sympathomimetic drugs. Assessing capillary refill time and vital signs will allow the nurse to assess perfusion as an indicator of the effectiveness of the infusing drug. Dietary intake, compliance with treatment plan, and effectiveness of comfort measures are all important assessments but the priority assessment is perfusion.
B (Ibutilide is specifically indicated only for treatment of recent-onset atrial fibrillation and flutter.)
The patient has been prescribed ibutilide (Corvert), a class III antiarrhythmic drug. The nurse is aware that this drug has been prescribed for which reason? Treatment of PSVT Conversion of recent-onset atrial fibrillation and flutter Conversion of life-threatening ventricular arrhythmias Treatment of dysrhythmias in patients with acute renal failure

The patient has developed thrombocytopenia.
Which patient finding would cause the nurse to hold the 8 AM dose of verapamil [Calan]?
The patient has hypotension. A patient who is scheduled to receive verapamil [Calan], a calcium channel blocker (CCB), should have blood pressure and pulse assessed prior to administration. Hypotension would be a reason to hold the drug. Verapamil [Calan] is given for atrial flutter. Patients with angina may receive CCBs for their vasodilating effects. Tachycardia is not a reason to hold the drug; CCBs decrease the heart rate.
A nurse is preparing to administer heparin intravenously (IV) to a patient who was admitted with an acute pulmonary embolus. Which response by the nurse is appropriate when the patient asks why the drug is given IV rather than orally?
Heparin is poorly absorbed by the gastrointestinal (GI) tract. Heparin is poorly absorbed by the GI tract and is therefore not available in an oral form. It is given parenterally (IV or SQ).
A patient who was started on continuous intravenous heparin for a pulmonary embolus complains of "a lot of bruises" and "pink urine." Laboratory values show that platelets have decreased from 225,000 mm3 to 75,000 mm3. Which condition would the nurse most likely consider with these signs and symptoms?
Heparin-induced thrombocytopenia (HIT) from heparin Significant decrease in platelets can indicate HIT. With decreased platelets, evidence of bleeding, such as multiple bruises and hematuria (blood in urine), can occur.
The nurse is preparing to administer dabigatran. Dabigatran would be most appropriate for a patient with which medical condition?

The patient is eating breakfast.
The nurse is planning care for an 18-year-old woman with acne who is scheduled to start taking isotretinoin. The nurse should establish which outcomes on the plan of care? Select all that apply.
Isotretinoin has demonstrated teratogenic effects and must not be used during pregnancy. All female patients must use two effective forms of birth control and have one negative pregnancy test result before monthly refills. iPLEDGE is a risk-management program used by the prescriber, pharmacist, and patient to ensure that the patient will not become pregnant while taking isotretinoin. Triglyceride levels should be measured periodically, because they may become elevated with the treatment. Depression and suicide are rare effects without direct causal links to isotretinoin, but patients should still be taught to report any signs of depression to a clinician.
4
It is important for the nurse to monitor a patient for the Mazzotti reaction if the patient takes which medication? 1 Praziquantel [Biltricide] 2 Diethylcarbamazine [Hetrazan] 3 Pyrantel [Pin-X] 4 Ivermectin [Stromectol]

The prototype of Azole antifungals is __________ - Inhibits the synthesis of ergosterol = increased membrane permeability and leakage of cellular components. Drug of choice for: blastomycosis, histoplasmosis, paracoccidioidomycosis, and sporotrichosis. And an alternative to amphotericin for: aspergillosis, candidiasis, and coccidioidomycosis. - undergoes extensive hepatic metabolism (lose 40% of dose in urine) - take with food and/or cola to increase absorption - GI sx most common SE - Serious: cardiac suppression and liver injury
After reviewing the chart of a patient with hypertension who is receiving angiotensin-converting enzyme inhibitors, which finding will cause the nurse to notify the provider?
Pregnancy test positive The nurse must notify the provider about the pregnancy test. Angiotensin-converting enzyme (ACE) inhibitors can cause serious fetal harm especially during the second and third trimesters of pregnancy, and hence, must not be given to pregnant women. ACE inhibitors—along with angiotensin receptor blockers (ARBs) and direct renin inhibitors (DRIs)—are the only antihypertensive drugs specifically contraindicated during pregnancy. Afebrile means not having a temperature, which is normal. The patient's history of following the DASH diet is appropriate and healthy. A slightly decreased potassium level, while abnormal, is not as urgent as a positive pregnancy test, and ACE inhibitors are potassium sparing so they may help raise the level.

3 (The most appropriate outcome criteria when taking antidysrhythmic medications is that the client's symptoms of dysrhythmia and subsequent decreased cardiac output are decreased and/or alleviated. The client's peripheral pulses should be equal, strong, and regular bilaterally with warm, pink extremities. Weight gain of 5 pounds or more in one week is of concern, and the prescriber should be notified. Heart failure may be developing or worsening if the client already has known heart failure. The systolic blood pressure should be > 90 mm Hg.)
What is the most appropriate outcome criteria for a client who has been prescribed an antidysrhythmic medication? 1 Palpated radial pulses > pedal pulses 2 Weight gain in one week 5 lb 3 Cardiac output increased 4 Systolic blood pressure 90 mm Hg
2 (When antidysrhythmic drugs are administered, the nurse should monitor vital signs, especially pulse rate and blood pressure. If the pulse is lower than 60 beats/min, notify the prescriber.)
What is the most important assessment to complete before the nurse administers an antidysrhythmic medication? 1 Respiratory rate 2 Pulse 3 Auscultate lungs 4 Temperature
B In response to stress, the adrenal cortex secretes increased amounts of glucocorticoids and the adrenal medulla secretes increased amounts of epinephrine. Working together, glucocorticoids and epinephrine help to augment and increase the blood glucose concentration, blood pressure, coagulation factors, and oxygenation as part of the fight-or-flight mechanism (stress response). Thus they provide more fuel for cells. Cortisol increases oxygen delivery to the vital organs by increasing the blood flow. Blood coagulability also increases.
What role does the release of cortisol play in the stress response? A. Decreases oxygen delivery B. Provides more fuel for cells C. Reduces blood flow to vital organs D. Decreases coagulability of blood

A nurse is providing patient education to a patient as part of her work in a fertility clinic. The nurse explains possible reasons for infertility. When explaining how the ovaries are involved in conception, what will the nurse stress? A)Ova quickly degenerate and most are absorbed in the body before the age of 12. B)The ovaries at birth contain all of the ova that a woman will have. C)Ova aggregate, causing millions to be contained in a storage site called a follicle. D)Follicles produce only estrogen; the uterus produces progesterone.
b It would be important to explain that the woman's ova do not increase or decrease from birth to childbearing years. The nurse will stress that all the ova that a woman will have will be present at birth. The patient should understand that if she does not ovulate 1 month or for several months, it is not because she has done something to her body to cause this. Ova slowly degenerate over a lifetime or they are released once a month until menopause is complete. Each ovum is contained in a storage site called a follicle, which produces the female sex hormones, estrogen and progesterone.
Because of the potential for serious cardiac effects, minoxidil has a
black box warning, and its use is reserved for severe hypertension, when other safer drugs have failed.
CCBs work by
blocking the slow inward flow of calcium ions into the slow (calcium) channels in the cardiac conduction tissue. Conduction is limited to the atria and the atrioventricular (AV) node, where conduction is prolonged, and the tissues are made more refractory to stimulation. CCBs have little effect on the ventricular tissues.

Which are actions of angiotensin II? Select all that apply. 1. Dilates vessels 2. Raises blood pressure 3. Causes cardiac remodeling 4. Catalyzes angiotensinogen 5. Stimulates aldosterone release
2. Raises blood pressure 3. Causes cardiac remodeling 5. Stimulates aldosterone releases (The most prominent actions of angiotensin II are vasoconstriction (not dilation) and stimulation of aldosterone release. Both actions raise blood pressure. In addition, angiotensin II can act on the heart and blood vessels to cause remodeling and hypertrophy. Renin catalyzes angiotensinogen.)
The nurse is administering several medications at 8 a.m. Which medication will decrease blood pressure by blocking angiotensin II receptor sites? 1. Enalapril 2. Valsartan 3. Eplerenone 4. Furosemide
2. Valsartan (Valsartan is an angiotensin II receptor blocker that is indicated for management of hypertension. Furosemide is a loop diuretic. Eplerenone is an aldosterone antagonist. Enalapril is an angiotensin-converting enzyme inhibitor.)
Which statement is true regarding the renin-angiotensin-aldosterone system? 1. Renin is the by-product of angiotensinogen catalysis. 2. Angiotensinogen is catalyzed by renin into angiotensin 1. 3. Angiotensinogen catalyzes the conversion of angiotensin I and angiotensin II. 4. ACE concerts angitoentsinogen to angiotensin I.
2.Angiotensinogen is catalyzed by renin into angiotensin 1. (Angiotensinogen is catalyzed by renin into angiotensin I (inactive). ACE converts angiotensin I into angiotensin II (active).)

3
Which area should the nurse assess to best determine systemic circulation function? 1 Heart 2 Lungs 3 Periphery 4 Lymph nodes
3
The nurse will most likely administer a combination drug of hydralazine and isosorbide dinitrate to patients belonging to which ethnic group? 1. Asian American 2. Native American 3. African American 4. Mexican American
3. African American (Hydralazine is also available in fixed-dose combination with isosorbide dinitrate (a vasodilator) sold as BiDil. BiDil is the first drug product approved for treating a specific ethnic group—namely, African Americans.)
The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure? 1. Renin 2. Angiotensin I 3. Angiotensin II 4. Angiotensin III
3. Angiotensin II (Angiotensin II is a potent vasoconstrictor. It participates in all the pathways regulated by the renin-angiotensin-aldosterone system. Angiotensin I is a precursor to angiotensin II; angiotensin III is formed by degradation of angiotensin II and is less potent. Renin catalyzes the conversion of angiotensinogen to angiotensin I.)
A staff member asks how calcium channel blockers (CCBs) work. Which response should the nurse provide? 1. CCBs increase arterial pressure 2. CCBs block reabsorption of sodium 3. CCBs relax vascular smooth muscle 4. CCBs have a positive inotropic effect
3. CCBs relax vascular smooth muscle (By blocking calcium channels, CCBs inhibit muscle contraction in the coronary arteries and peripheral arteries, resulting in relaxed vascular smooth muscle (vasodilation). CCBs have a negative inotropic effect by blocking calcium entry, which decreases the force of contractions. CCBs have no direct role in sodium activity. Vasodilation from CCBs decrease arterial pressure.)
Which patient finding would cause the nurse to hold the 8 a.m. dose of verapamil? 1. The patent has atrial flutter. 2. The patient has tachycardia. 3. The patient has hypotension. 4. The patient has angina pectoris.
3. The patient has hypotension. (A patient who is scheduled to receive verapamil, a calcium channel blocker (CCB), should have blood pressure and pulse assessed prior to administration. Hypotension would be a reason to hold the drug. Verapamil is given for atrial flutter. Patients with angina may receive CCBs for their vasodilating effects. Tachycardia is not a reason to hold the drug; CCBs decrease the heart rate.)
Which dose of salicylate can cause severe toxicity in a patient?
300-500 mg/kg
For which patients is the use of an angiotensin-converting enzyme (ACE) inhibitor contraindicated?
32-year-old female patient who is 4 months pregnant 62-year-old male patient with a history of renal artery stenosis 29-year-old female patient with a potassium level of 5.2 mEq/L
For which patients is the use of an angiotensin-converting enzyme (ACE) inhibitor contraindicated?
32-year-old female patient who is 4 months pregnant ACE inhibitors are contraindicated in pregnancy. 62-year-old male patient with a history of renal artery stenosis ACE inhibitors are contraindicated with renal artery stenosis. 29-year-old female patient with a potassium level of 5.2 mEq/L ACE inhibitors are contraindicated with high serum potassium.
A patient is prescribed lisinopril [Prinvil] as part of the treatment plan for heart failure. Which finding indicates the patient is experiencing the therapeutic effect of this drug? 1 Jugular vein distention 2 Potassium level of 3.5 mEq/L 3 + 2 edema of the lower extremities 4 Crackles in the lungs are no longer heard
4 Because angiotensin-converting enzyme (ACE) inhibitors promote venous dilation, they provide the therapeutic effect of reducing pulmonary congestion and peripheral edema. Absence of previously heard crackles would be an indicator of effectiveness. Edema and jugular vein distention are manifestations of heart failure. A potassium level of 3.5 mEq/L is a normal value.
The nurse is administering several medications at 8 AM. Which medication will decrease blood pressure by blocking angiotensin II receptor sites? 1 Enalapril 2 Furosemide 3 Eplerenone [Inspra] 4 Valsartan [Exforge]
4 Valsartan [Exforge] is an angiotensin II receptor blocker (ARB) that is indicated for management of hypertension. Furosemide is a loop diuretic. Eplerenone [Inspra] is an aldosterone antagonist. Enalapril is an angiotensin-converting enzyme (ACE) inhibitor.
A patient asks the nurse why dronedarone needs to be taken with food. The nurse responds knowing that bioavailability of dronedarone is at which level without food?
4% Dronedarone's bioavailability without food is low at 4%. To increase the available drug for the body to use (bioavailability), dronedarone must be taken with food. Food, especially high-fat food, increases the bioavailability to 15%. The rest of dronedarone is bound to protein, which is then excreted.
Which medication works by preventing angiotensin II from binding with its receptor sites? 1. Quinapril 2. Aliskiren 3. Elperenone 4. Candesartan
4. Candesartan (Candesartan is an angiotensin II receptor blocker and thus prevents the binding of angiotensin II at its receptor sites. Quinapril is an angiotensin-converting enzyme inhibitor, aliskiren is a direct renin inhibitor, and eplerenone is a selective aldosterone receptor blocker.)
The nurse is administering 8:00 a.m. medications for hypertension. Which drugs should the nurse identify as aldosterone antagonists? Select all that apply. 1. Losartan 2. Alikiren 3. Benazepril 4. Eplerenone 5. Spironolactone
4. Eplerenone 5. Spironolactone (Eplerenone and spironolactone are both aldosterone antagonists. Aliskiren is a direct renin inhibitor. Losartan is an angiotensin II receptor blocker (ARB), and benazepril is an angiotensin-converting enzyme (ACE) inhibitor.)
The nurse is caring for a patient prescribed aliskiren. How does this medication lower blood pressure? 1. It prevents angiotensin II from binding to its receptors. 2. It selectively blocks aldosterone receptors in the kidneys. 3. It blocks the conversion of angiotensin I to angiotensin II. 4. It inhibits the conversion of angiotensinogen to angiotensin I.
4. It inhibits the conversion of angiotensinogen to angiotensin I. (Aliskiren was the first direct renin inhibitor on the market. It binds with renin and thus inhibits the conversion of angiotensinogen to angiotensin I. The other items describe angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and selective aldosterone receptor blockers.)
The nurse is preparing to administer minoxidil 5 mg orally. What is the only cardiovascular indication for this medication? 1. Heart failure 2. Angina pectoris 3. Myocardial infarction 4. Sever hypertension
4. Sever hypertension (Because of its serious adverse effects, minoxidil is reserved for patients who have failed to respond to safer drugs. The only cardiovascular indication for minoxidil is severe hypertension.)
The nurse is caring for a patient receiving hydralazine. The health care provider prescribes propranolol. A drug such as propranolol is often combined with hydralazine for which purpose? 1. To prevent heart failure 2. To reduce the risk of headache 3. To improve hypotensive effects 4. To protect against reflex tachycardia
4. To protect against reflex tachycardia. (Hydralazine is a vasodilator that lowers blood pressure, but it can also trigger reflex tachycardia. Beta blockers, such as propranolol, are often added to the regimen to normalize the heart rate.)

A
Which patients are good candidates for fenofibric acid?
A 66-year-old patient with phenylketonuria A 48-year-old patient with iron-deficiency anemia
2 (Bradycardia is an adverse effect of lidocaine (Xylocaine), which the nurse should monitor for in the patient. Anorexia is an adverse effect of quinidine (Quinidex), but is not associated with lidocaine. Bronchospasm is a potential side effect of beta blockers. Prodysrhythmic effects are observed in patients who are taking propafenone (Rythmol).)
A nurse is caring for a patient who is taking lidocaine (Xylocaine). Which adverse effect should the nurse monitor for in the patient? 1 Anorexia 2 Bradycardia 3 Bronchospasm 4 Prodysrhythmic effect
Which nurse should not be assigned to treat a patient who is receiving ribavirin in an aerosol formulation? 1 A nurse who is pregnant 2 A nurse who has a low-grade fever 3 A nurse who has not had chickenpox 4 A nurse on light duty because of a back injury
A nurse who is pregnant
A A common adverse effect of steroid therapy is hyperglycemia. Therefore, the nurse should look for uncontrolled diabetes mellitus in the patient. Rheumatoid arthritis is a chronic autoimmune disorder that commonly causes inflammation and tissue damage in joints and it is not directly linked with steroid therapy. Destruction of red blood corpuscles leads to septic shock. Steroid therapy is a remedy for chronic obstructive pulmonary disease.
A patient is about to receive steroid therapy. What symptoms should the nurse assess? A. Uncontrolled diabetes mellitus B. Rheumatoid arthritis C. Septic shock D. Chronic obstructive pulmonary disease
How can the nurse determine if a patient will tolerate an amphotericin B infusion?
Administer a test dose
Viral hepatitis is the most common liver disorder. Which strains of hepatitis can cause chronic hepatitis? Select all that apply.
All six hepatitis viruses can cause acute hepatitis, but only B, C, and D also cause chronic hepatitis.
A patient with diabetes is prescribed levothyroxine for hypothyroidism. Which action from the health care provider should the nurse anticipate occurring for this patient? No change to current diabetic treatments A decrease in the patient's dose of insulin A change from insulin to an oral diabetic drug An increase in the patient's dose of insulin
An increase in the patients dose of insulin
The nurse provides teaching to a patient with chronic obstructive pulmonary disease who has been prescribed budesonide (Pulmicort) two puffs and fluticasone (Flovent) three puffs t.i.d. The nurse evaluates that further teaching is needed when the patient makes what statement? A)"Take all five puffs as quickly as possible." B)"Replace the inhalers before they run out." C)"Rinse the mouth after taking the medication." D)"Continue medication even when symptoms start to subside."
Ans:A Feedback: The nurse needs to review how to administer the drug via inhalation because the patient must hold the medication in the airways as long as possible before exhaling and should not try to rush the treatment. The other statements are correct and would not require clarification.
There can be interference with cancer chemotherapy in what phase of the cell cycle? A)G0 phase B)G1 phase C)G2 phase D)S phase
Ans:A Feedback: During the G0 phase, the cell is stable. Cells in this phase can interfere with cancer chemotherapy because these drugs usually work on actively dividing cells, leaving resting cells mostly untouched. When the resting cells are stimulated to become active and regenerate, the cancer can return. This is the reason that cancer chemotherapy regimens are complicated and extended over a period of time. In the G1 phase, a cell is stimulated to emerge from its resting phase. During this time, the cell synthesizes the substances needed for DNA formation. The S phase involves the actual synthesis of DNA, and during the G2 phase, the cell produces all the substances that are required for the manufacture of the mitotic spindles.
The nurse is caring for a child receiving a central nervous system (CNS) stimulant who was admitted to the pediatric intensive care unit following repeated seizures after a closed head injury. The physician orders phenytoin to control seizures and lorazepam to be administered every time the child has a seizure. What is the nurse's priority action? A)Call the doctor and question the administration of phenytoin. B)Call the doctor and question the administration of lorazepam. C)Wait 24 hours before beginning to administer phenytoin. D)Wait 24 hours before beginning to administer lorazepam.
Ans:A Feedback: The combination of CNS stimulants with phenytoin leads to a risk of increased drug levels. Patients who receive such a combination should be monitored for toxicity. There is no contraindication for use of lorazepam.
The pharmacology instructor is discussing antimicrobials with the nursing class. What would the instructor tell the students about the mechanism of action of antimicrobials? (Select all that apply). A)Preventing cell division B)Causing cell death C)Inhibiting cell wall synthesis D)Causing leakage of cell wall allowing fluid to leak in E)Inhibiting synthesis of ribonucleic acid (RNA)
Ans:A, B, C Feedback: Sites of cellular action of carbapenems, ketolides, lincosamides, aztreonam, penicillins, sulfonamides, tetracyclines, and antimycobacterials. Carbapenems, ketolides, and lincosamides change protein function and prevent cell division or cause cell death. Aztreonam alters cell membranes to allow leakage of intracellular substances and causes cell death; it does not cause leakage of fluid into the cell. Penicillins prevent bacteria from building their cells during division. Sulfonamides inhibit folic acid synthesis for RNA and deoxyribonucleic acid production but does not inhibit RNA synthesis
What are the primary uses of neuromuscular junction blockers (NMJ) blockers? (Select all that apply.) A)To facilitate endotracheal intubation B)To sedate patient for general anesthesia C)To prevent injury during electroconvulsive therapy D)To provide greater ease in extubating patient E)To facilitate mechanical ventilation
Ans:A, C, EFeedback: NMJ blockers are primarily used as adjuncts to general anesthesia, to facilitate endotracheal intubation, to facilitate mechanical ventilation, and to prevent injury during electroconvulsive therapy. NMJ blockers do not sedate the patient who will be paralyzed after administration but will remain alert unless another medication is given. These medications would not be given before extubation because respiratory muscles would be paralyzed, resulting in the inability to breathe.
The nurse administers promethazine (Phenergan) to the patient before sending the patient to the preoperative holding area. What is the rationale for administration of this drug? A)SedationB)Oral secretions C)Hypotension and bradycardia D)Confusion
Ans:AFeedback: Antihistamines (promethazine, diphenhydramine [Benadryl]) can be very sedating in some people. They are used as preoperative medications and postoperatively to decrease the need for narcotics. Promethazine is not given for hypotension, bradycardia, confusion, or oral secretions.
When causing depolarization of the muscle membranes, what neurotransmitter interacts with the nicotinic cholinergic receptors leading to the release of calcium ions? A)AcetylcholineB)SerotoninC)D-gluconamidoethyl methacrylate (GAMA) D)Epinephrine
Ans:AFeedback: At the acetylcholine receptor site on the effector's side of the synapse, the acetylcholine interacts with the nicotinic cholinergic receptors causing the depolarization. Serotonin, GAMA, and epinephrine are not part of muscle contraction and relaxation.
The nurse administers prednisone orally at 8 am. When would the nurse expect the drug to reach peak effect? A)9 to 10 am B)12 to 1 pm C)8:30 to 9:00 am D)4 to 6 pm
Ans:AFeedback: Prednisone's peak effect occurs 1 to 2 hours after administering the drug. If given at 8 am, the expected peak would occur between 9 and 10 am.
A patient is taking low-dose corticosteroids on a long-term basis for chronic obstructive pulmonary disease. The nurse assesses this patient knowing prolonged use of corticosteroids puts the patient at risk for what? A)Adrenal stormB)Adrenal atrophyC)Stunted growth D)Hypothalamic insufficiency
Ans:B Feedback: Prolonged use of corticosteroids suppresses the normal hypothalamic-pituitary axis and leads to adrenal atrophy from lack of stimulation. The other options are all distracters for this question with no connection to long-term use of corticosteroids.
What classification of medication will the nurse administer concurrently with amphotericin B (Fungizone) to help minimize the adverse reactions to this medication? A)SedativesB)Antipyretics C)Beta-adrenergic blockers D)Diuretics
Ans:BFeedback: Amphotericin B is often given with antipyretics to improve patient comfort and to minimize adverse reactions. Sedatives, beta- adrenergic blockers, and diuretics are not indicated for use with amphotericin B unless the patient has a coexisting diagnosis that would indicate a need for these drugs.
A patient with a gram-negative infection is being treated with an aminoglycoside. What system should the nurse expect to monitor closely while the patient is taking this medication? A)Respiratory system B)Ophthalmic system C)Renal system D)Musculoskeletal system
Ans:C Feedback: Renal function should be tested daily because aminoglycosides depend on the kidney for excretion and if the glomerular filtration rate (GFR) is abnormal it may be toxic to the kidney. The results of the renal function testing could change the daily dosage. Aminoglycosides do not usually adversely affect respiratory, hepatic, or musculoskeletal function, although baseline data concerning these systems is always needed.
When giving beta-specific adrenergic agonists, at what age is an adult dose given? A)10 years B)11 years C)12 years D)13 years
Ans:C Feedback: Adult doses are given to children who are 12 years and older (see dosages in Table 30.3, page 497.) Therefore, the other options are incorrect.
The nurse is caring for a patient who experiences anxiety and insomnia and is prescribed benzodiazepines. When developing the plan of care, what would be an appropriate nursing diagnosis related to potential adverse effects of the drug? A)Provide patient teaching about drug therapy. B)Anxiety related to drug therapy. C)Risk for injury related to central nervous system (CNS) effects. D)Avoid preventable adverse effects, including abuse and dependence.
Ans:C Feedback: The most appropriate nursing diagnosis related to adverse effects of the drug is risk for injury related to CNS effects because benzodiazepines can have many CNS adverse effects. Anxiety is the condition for which drug therapy is prescribed not related to drug therapy. Patient teaching and avoiding adverse effects are interventions and not nursing diagnoses.
What would the nurse assess for when benzodiazepines are abruptly stopped? A)Urinary retention and change in sexual functioning B)Dry mouth, constipation, nausea, and vomiting C)Nausea, headache, vertigo, malaise, and nightmares D)In most cases nothing significant
Ans:CFeedback: Abrupt cessation of these drugs may lead to a withdrawal syndrome characterized by nausea, headache, vertigo, malaise, and nightmares. When benzodiazepines are stopped abruptly the likelihood of withdrawal symptoms increases with the length of time the patient took the medication. Urinary retention, change in sexual functioning, dry mouth, constipation, nausea, and vomiting are all common adverse effects of the medications classified as benzodiazepines.
For what reason might a nurse administer androgen injections to a 9-year-old boy? A)Ovarian atrophy B)Dwarfism C)Acromegaly D)Hypogonadism
Ans:D Feedback: Androgens are used pharmacologically to treat hypogonadism or to increase protein growth and red blood cell production. Androgens are not used in a male to treat ovarian atrophy. Androgens are not used to treat dwarfism or acromegaly.
An woman is prescribed androgens. The nurse teaches the patient to anticipate what effect from the drug? A)Atrophy of breasts B)Rapid bone growth C)Loss of pubic hair D)Nervousness
Ans:D Feedback: Antiestrogen effects—flushing, sweating, vaginitis, nervousness, and emotional lability—can be anticipated when these drugs are used in women. When androgens are administered to women you would not expect the results to include atrophy of the breasts, rapid bone growth, or loss of pubic hair.
Which muscle relaxant was found to be embryotoxic in animal studies? A)Carisoprodol (Soma) B)Botulinum toxin A (Botox) C)Cyclobenzaprine (Flexeril) D)Dantrolene (Dantrium)
Ans:D Feedback: Dantrolene crosses the placenta and was found to be embryotoxic in animal studies. Botulinum toxin A, carisoprodol, and cyclobenzaprine are not known to be embryotoxic.
The nurse is caring for a patient who has not been able to sleep. The physician orders a barbiturate medication for this patient. What adverse effect should the nurse teach the patient about? A)Double vision B)ParanoiaC)TinnitusD)Thinking abnormalities
Ans:D Feedback: The most common adverse effects are related to general central nervous system (CNS) depression. CNS effects may include drowsiness, somnolence, lethargy, ataxia, vertigo, a resembling a "hangover," thinking abnormalities, paradoxical excitement, anxiety, and hallucinations. Barbiturate drugs generally do not cause double vision, paranoia, or tinnitus.
A patient has stepped on a rusty nail and is exhibiting signs of muscle rigidity and contractions. The patient's wife called the emergency department (ED) and the triage nurse told her to bring him in. The ED nurse will have which drug available for administration when the patient arrives? A)Carisoprodol (Soma) B)Cyclobenzaprine (Flexeril) C)Metaxalone (Skelaxin) D)Methocarbamol (Robaxin)
Ans:D Feedback: The patient is exhibiting signs of tetanus and methocarbamol (Robaxin) is indicated for treatment. Carisoprodol, cyclobenzaprine, and metaxalone are not used to treat tetanus.
When a 5-year-old patient is prescribed oxandrolone (Oxandrin) to promote weight gain, how would the nurse expect the drug to be administered? A)Long-term B)Short-term C)Continuous D)Intermittent
Ans:D Feedback: Oxandrin is given intermittently to pediatric patients and should not be used on a daily basis for short, long, or continuous therapy.
An older adult African American patient comes to the clinic and is diagnosed with generalized anxiety disorder (GAD). The physician orders oral flurazepam 30 mg. What is the nurse's priority action? A)Teach the patient about the prescribed medication. B)Administer the first dose of medication. C)Tell patient to take first dosage after driving home. D)Talk to the physician about the dosage.
Ans:DFeedback: If an anxiolytic or hypnotic agent is the drug of choice for an African American patient, the smallest possible dose should be used, and the patient should be monitored very closely during the first week of treatment. Dosage adjustments are necessary to achieve the most effective dose with the fewest adverse effects. In addition, older adults also require careful titration of dosage. Older patients may be more susceptible to the adverse effects of these drugs, from unanticipated central nervous system (CNS) adverse effects including increased sedation, dizziness, and even hallucinations. Dosages of all of these drugs should be reduced and the patient should be monitored very closely for toxic effects and to provide safety measures if CNS effects do occur. As a result, the priority action is to talk to the physician about the dosage. The other actions may be appropriate after a proper dosage is ordered.
Which description of the therapeutic use of hydrocortisone in Addison's disease is accurate? As an antiinflammatory agent To modulate allergic response As replacement cortisol therapy To promote immunosuppression
As replacement cortisol therapy
In what part of the conduction pathway in a healthy heart is the electrical impulse delayed to provide time for the blood to fill the ventricles?
Atrioventricular node Impulses originate in the sinoatrial (SA) node and then travel through the atrioventricular (AV) node to reach the ventricles. The impulse is delayed at the AV node to provide time for the ventricles to fill before they contract.
A male patient is admitted to the emergency department (ED) with chest pain. The patient is diagnosed with angina pectoris. He is being discharged with an order for nitroglycerin SL PRN. What action should the nurse take when the patient reports chest pain? A.Apply a nitroglycerin transdermal patch to the patient's back. B.Administer a tablet under the patient's tongue and repeat the action in 5 and 10 minutes if the pain has not subsided. C.Place 2 nitroglycerin tablets under the patient's tongue and call the physician. D.Have the client swallow a tablet and repeat in 10 minutes.
B
The nurse is caring for a patient receiving a nitroprusside [Nipride] intravenous infusion. The patient's wife asks why furosemide [Lasix] is being prescribed along with this drug. The nurse's response is based on which concept? A. Furosemide will help reduce reflex tachycardia. B. Many vasodilators cause retention of sodium and water. C. Thiocyanate may accumulate in patients receiving nitroprusside. D. Vasodilators can cause serious orthostatic hypotension.
B. Many vasodilators cause retention of sodium and water. Nitroprusside is a potent vasodilator that can cause retention of sodium and water. Furosemide, a diuretic, often is combined with nitroprusside to reduce the risk of edema and fluid retention. Furosemide does not reduce reflex tachycardia. Thiocyanate can accumulate in patients receiving nitroprusside, but furosemide does not help prevent or treat that. Vasodilators can cause serious orthostatic hypotension, but that is not the rationale for adding furosemide to the regimen.
A patient with healing stab wounds to the arms and legs is brought to the emergency department with complaints of chest pain. The patient was diagnosed with acute myocardial infarction, and alteplase was prescribed. The nurse would closely monitor the patient for which complications following the administration of alteplase?
Bleeding
Which plasma lipoprotein level is most Concerning when considering the risk of coronary atherosclerosis? A: elevated cholesterol B. elevated HDL C. elevated LDL D. elevated VLDL
C
NSAIDs inhibit ___
COX-1 and COX-2
B (Calcium channel blockers cause coronary vasodilation, a negative inotropic effect, a negative chronotropic effect, and a negative dromotropic effect.)
Calcium channel blockers have which pharmacodynamic effect? Positive inotropic effect Coronary vasodilation Positive chronotropic effect Shortened refractory period
The nurse is teaching a course on calcium channel blockers. Which description of the mechanism of action will the nurse provide?
Calcium channel blockers prevent contraction of smooth muscle and allow dilation of the coronary arteries.
How are cephalosporins like penicillins? Select all that apply.
Cephalosporins have a mechanism of action like penicillins; they are both bactericidal antibiotics, activate autolysin enzymes, bind to penicillin-binding proteins (PBPs), and are active only against bacteria undergoing growth and division. Only penicillin takes up excess water and causes the cell wall to rupture.
A 58-year-old male patient has been prescribed ezetimibe 10 mg PO each evening. In addition to ezetimibe, he takes simvastatin for dyslipidemia, tamsulosin for benign prostatic hyperplasia, levothyroxine for hypothyroidism, and cyclosporine for plaque psoriasis. Which drug that the patient is currently taking does a nurse identify as potentially interacting with ezetimibe, and what is the reason for the reaction?
Cyclosporine; the combination of cyclosporine and ezetimibe increases levels of ezetimibe and risk for side/adverse effects.
A patient is receiving cancer chemotherapy. Which type of drug is the nurse administering?
Cytotoxic agents

A nurse reviews the cardiac monitor on a patient who is receiving dronedarone for paroxysmal atrial fibrillation. Which cardiac dysrhythmia would most alarm the nurse?
Torsades de pointes
A nurse reviews the cardiac monitor on a patient who is receiving dronedarone for paroxysmal atrial fibrillation. Which cardiac dysrhythmia would most alarm the nurse?
Torsades de pointes Dronedarone prolongs the PR and QT interval and widens the QRS complex. These effects to the heart increase the risk of torsades de pointes, a ventricular dysrhythmia.
Which statements about the pharmacodynamic and pharmacokinetic of digoxin toxicity are correct?
Toxicity can occur easily due to the narrow therapeutic range of digoxin. The half-life and duration of digoxin are very long. Digoxin increases myocardial contraction, which increases cardiac output. Oral digoxin begins to work in 30 minutes to 2 hours.The nurse will include this teaching because oral digoxin does begin to work (onset) in 30 minutes to 2 hours.

Which medication is the treatment of choice for most intestinal roundworms? 1 Albendazole [Albenza] 2 Pyrantel [Pin-X] 3 Mebendazole [Vermox] 4 Ivermectin [Stromectol]
Adenosine stimulates the
adenosine-sensitive potassium channels in the sinoatrial (SA) node and internodal tracts. The use of adenosine results in specific effects on the heart and the electrocardiogram (ECG). The nurse must be aware of these effects and understand how adenosine is used therapeutically.
Methylxanthines, such as aminophylline, theophylline, and caffeine, block receptors for
adenosine. Patients who are taking aminophylline, theophylline, or caffeine need larger doses of adenosine, and even then adenosine may not be effective. Dipyridamole, an antiplatelet drug, blocks cellular uptake of adenosine and can thereby intensify its effects.

advanced age hypothyroidism
Warfarin binds with which molecule in the body? keratin platelets ferritin albumin
albumin (99% protein bound)
Asystole can occur with
amiodarone. The patient must be on a continuous cardiac monitor, and the nurse should be prepared to administer cardiopulmonary resuscitation if asystole does not spontaneously convert.
A patient is scheduled to start taking sildenafil [Viagra]. The nurse should recognize that the patient is at risk for developing an adverse cardiac event if the patient's history reveals which condition?
angina
PO verapamil and diltiazem are indicated for
angina pectoris and essential hypertension. In patients with atrial fibrillation or flutter, verapamil may be used along with digoxin to control the ventricular rate. Sustained-release (SR) formulations must be swallowed whole; crushing and/or chewing is not advised. SR formulations are used in the setting of essential hypertension. Verapamil PO: 240 to 480 mg/day in 3 to 4 divided doses Diltiazem PO: 120 to 360 mg once daily
A patient on subcutaneous anticoagulant calls the clinic about a cut received on the hand. Which initial action would the nurse tell the patient to take?
apply direct pressure for 5-10 minutes
Topical corticosteroids
are often used to treat skin, eye, and ear inflammatory conditions.
Mineralocorticoids
are responsible for the regulation of electrolytes, or mineral salts, in the body
Inhaled corticosteroids
are used in the management of respiratory diseases such as asthma.
In combination usually with isosorbide dinitrate, hydralazine can be used
as a short-term option to decrease afterload in patients experiencing heart failure.
This agent is highly effective for both prophylaxis and treatment of malaria caused by chloroquine-resistant plasmodia
atovaquone/proguanil
Verapamil and diltiazem are indicated for the treatment of
atrial flutter, atrial fibrillation, and paroxysmal supraventricular tachycardia. Ventricular rate is slowed by the suppression of impulse conduction through the AV node, which prevents the atria from driving the ventricles at an excessive rate. Verapamil and diltiazem are also indicated for the treatment of hypertension
Adenosine interaction with food
avoid caffeine ( may decrease effect)
Which teaching points would a nurse share with a 33-year-old female patient who was prescribed statin therapy?
avoid pregnancy Gastrointestinal distress can be minimized by taking with food and/or with at least 6 to 8 oz of water. Ensure she is getting plenty of exercise and a diet rich in vegetables, fruits, and fiber to help lower cholesterol levels.
Verapamil and diltiazem block the flow of
calcium into the cell via the slow calcium channels, which slows the sinoatrial (SA) nodal automaticity (negative chronotropic effect), delays the AV nodal conduction (negative dromotropic effect), and reduces myocardial contractility (negative inotropic effect). These effects are identical to those of beta blockers, which also promote calcium channel closure in the heart. The principal effect on the electrocardiogram (ECG) is prolongation of the PR interval, which reflects delayed AV conduction. Decrease in contractility assists the dilation of coronary and systemic arteries. The total peripheral resistance, blood pressure, and cardiac workload are decreased.
The drug of choice for mild to moderate acute attack caused by chloroquine-sensitive strains of P.falciparum or P. vivax is
chloroquine
This antibacterial is used as an adjunct to quinine to treat malaria caused by chloro-resistant P. falciparum or P. vivax
clindamycin
Which drug would a nurse anticipate may require additional monitoring because of reduced absorption of vitamins A, D, E, and K?
colestipol
A nurse receives a prescription for gemfibrozil for a patient who is also receiving cyclosporine (posttransplant) and amoxicillin (infection). What is the rationale for the nurse's intervention to contact the health care provider?
combination can cause nephrotoxicity
Adverse drug effects result from the blockade of calcium channels in the heart or smooth muscle of the intestine or from vasodilation. Adverse effects include
constipation, bradycardia, heart block, hypotension, dyspnea, facial flushing, and edema of the ankles and feet. Other adverse effects include acute renal failure and Stevens-Johnson syndrome.
scabies
contagious skin disease transmitted by the itch mite
Remember, sodium nitroprusside is a very potent vasodilator. Patients receiving sodium nitroprusside for hypertensive emergencies require
continuous monitoring and will be cared for in an intensive care setting. The nurse will often titrate this medication according to the health care provider's prescription to a given blood pressure. By adjusting the rate of infusion, the blood pressure can be lowered. It is important to monitor carefully to avoid a precipitous drop in blood pressure.
Sodium nitroprusside can cause
cyanide poisoning due to the metabolism by-products of the drug. This is more common in patients with liver disease. The chances of cyanide poisoning are lower with slower infusion of the drug.
A nurse should recognize which as an indicator of P. falciparum malaria
dark urine, weakness and anemia
It is important for the nurse to evaluate for therapeutic response from vasodilator administration. When administered for hypertension, vasodilators should
decrease blood pressure. The nurse will also need to evaluate the patient for potential adverse and side effects from vasodilator administration.
The nurse will monitor for which therapeutic effect while administering quinidine?
decreased heart rate
Beta blockers and Class IV antidysrhythmic drugs have the same effects on the heart, which includes
decreased heart rate, AV conduction, and contractility. Beta blockers and Class IV antidysrhythmic drugs should be administered several hours apart to minimize the risk of cardiosuppression.
After administration, adenosine significantly
decreases the automaticity of the SA node and slows conduction through the AV node. It also interrupts AV reentry pathways. After adenosine administration, brief asystole is usually apparent on the ECG. Rarely is asystole sustained.
Caution is advised in patients with acute myocardial infarction, acute myocarditis, and severe pulmonary disease for what
digoxin
Teach the patient how to check pulse rate before taking
digoxin and to notify the health care provider if pulse rate is ≤60 beats/min, >100 beats/min, or irregular.
Cardiotoxicity is the major adverse drug effect of
digoxin. Hypokalemia, usually resulting from concurrent therapy with diuretics, enhances the risk of cardiotoxicity. Potassium levels must be monitored closely and kept within normal range (3.5 to 5 mEq/L). Other adverse effects include GI disturbances and central nervous system (CNS) changes. GI disturbances include anorexia, nausea, vomiting, and diarrhea. Changes to the CNS include depression, delirium, and hallucinations. These unwanted effects may signify impending toxicity and should be reported to the health care provider. Changes to vision, such as blurred vision or seeing yellow, can also occur with digoxin toxicity.
A known drug allergy is a contraindication for
digoxin. Other contraindications to consider include heart failure resulting from diastolic dysfunction, ventricular tachycardia/fibrillation, and SA blocks, such as second- or third-degree heart block. Digoxin can promote or worsen bradycardia.
The PR interval on an ECG is prolonged due to the slowed AV conduction produced by
digoxin. The ventricles are also affected, resulting in accelerated repolarization, which causes the QR interval to possibly shorten. ST segment depression also occurs frequently, and the T wave may be inverted or depressed. The QRS complex experiences little change.
Digoxin can also cause
dysrhythmias because digoxin can increase automaticity in the Purkinje fibers
Of all the CCBs, only the two in the nondihydropyridine subclass, verapamil and diltiazem, are used to treat
dysrhythmias.
Vasodilators the nurse should monitor patients for
eflex tachycardia, postural hypotension, and expansion of blood volume (secondary to prolonged decrease of blood pressure). The nurse should be aware that increased blood volume can cancel the beneficial effects of the vasodilator. To prevent this, patients often receive combination therapy with a diuretic, which prevents volume expansion and fluid retention. The nurse should assess lung sounds, edema, and skin turgor, monitoring carefully for signs of fluid retention.
Adenosine reduces the time for
electrical conduction through the atrioventricular (AV) node. As a result of this action, it is indicated for converting PSVT to sinus rhythm.
The nurse notes that quinine can
enhance atrioventricular conduction, causing dangerous increase in ventricular rate
A nurse should recognize that a patient who has which condition is at risk of developing an adverse reaction to mefloquine
epilepsey
Patients taking vasodilators are at increased risk for
falls. They should be educated about symptoms of hypotension (dizziness, lightheadedness) and instructed to sit or lie down if they experience these symptoms. Patients should also be informed that hypotension side effects can be decreased by transitioning slowly from a supine or seated position to an upright position
Side effects and adverse drug effects of adenosine are
few because of its extremely short half-life and duration of action. If unwanted effects occur, they usually last less than 1 minute. The most common side effects include facial flushing, nausea, dyspnea, and chest pressure.
The patient continues to bleed after receiving vitamin K for warfarin toxicity. The nurse anticipates administering which product to a patient who is not responding to vitamin K?
fresh frozen plasma
A hospitalized patient complains of acute chest pain. The nurse administers a 0.3-mg sublingual nitroglycerin tablet, but the patient continues to complain of pain. Vital signs remain stable. What is the nurse's next step? Apply a nitroglycerin transdermal patch. Give a second dose of nitroglycerin in 5 minutes Continue dosing at 10-minute intervals. Request an order for intravenous nitroglycerin.
give a second dose of nitroglycerin in 5 minutes (An initial dose of sublingual nitroglycerin is taken, and if the chest pain persists, as in this case, the patient should take another dose in 5 minutes. Transdermal delivery systems are not useful for terminating an ongoing attack. Dosing at 10-minute intervals is incorrect. If the patient fails to respond or if the pain intensifies, intravenous nitroglycerin may be indicated.)
Toxicity of the central nervous system with mefloquin is characterized by
hallucinations, depression and suicidal ideation
A patient has Pediculus humanus capitis. What should the nurse assess first when evaluating for improvement of the condition?
head
Common side effects of digoxin include
headache and hypotension.
Class IV antidysrhythmic drugs are generally well tolerated. Some common side effects include
headache, fatigue, drowsiness, edema, nausea, and rash.
Minoxidil side effects
headache, fatigue, nausea, vomiting, reflex tachycardia, pruritus, and hypertrichosis. Hypertrichosis is excessive growth of hair, usually starting on the face and then developing on the arms, legs, and back. This side effect is common in those who take the drug for 4 weeks or more.
Hydralazine side effects
headache, tremors, dizziness, anxiety, nausea, vomiting, anorexia, diarrhea, and reflex tachycardia.
Evaluate the effectiveness of the antidysrhythmic drugs by comparing
heart rate and rhythm with the baseline. Note any troublesome side effects. Also note any adverse drug effects and report them to the health care provider.
A patient is taking a calcium channel blocker (CCB) for stable angina. The patient's spouse asks how calcium channel blockers relieve pain. The nurse will explain that CCBs: improve coronary artery perfusion increase the heart rate to improve myocardial contractility. help relax peripheral arterioles to reduce afterload. increase the QT interval.
help relax peripheral arterioles to reduce afterload (CCBs promote relaxation of peripheral arterioles, resulting in a decrease in afterload, which reduces the cardiac oxygen demand. CCBs do not improve coronary artery perfusion. CCBs reduce the heart rate and suppress contractility; they do not affect the QT interval.)
Patients with G6PD deficiency are at risk for
hemolysis with primaquin or quinine administration
Class IV antidysrhythmic drugs should also be used with caution in patients with
hepatic dysfunction because these drugs are extensively metabolized in the liver.
Contraindications for Class IV antidysrhythmic drugs include
hypersensitivity, acute myocardial infarction, pulmonary congestion, Wolff-Parkinson-White syndrome, severe hypotension, cardiogenic shock, sick sinus syndrome, or second- or third-degree AV block. Class IV antidysrhythmic drugs should be used with caution in patients with preexisting heart failure.
Vasodilators can be used to treat many conditions, including
hypertension, angina, and heart failure. There are many different drugs that can cause vasodilation. Some of these drugs cause vasodilation by affecting arterioles, while others affect veins. There are some drugs that actually cause vasodilation of both arterioles and veins. For example, nitroglycerin, which is classified as a nitrate, causes vasodilation, acting primarily in venous circulation, which reduces preload and overall myocardial demand. Understanding how a drug produces vasodilation is key for the health care provider to determine the appropriate vasodilating drug.
Sodium nitroprusside is the drug of choice for
hypertensive emergencies.
Digoxin toxicity can occur with
hypokalemia, which can worsen cardiac dysrhythmias.
Evaluate the therapeutic effects of Class IV antidysrhythmic drugs (CCBs) while minimizing adverse drug effects such as
hypotension, bradycardia, and heart block. Monitor for any evidence of heart failure, such as dyspnea, swelling to the extremities, and adventitious lung sounds. The patient should also be evaluated for any evidence of prolonged QT interval or chest pain. Determine drug adherence. Because the liver metabolizes Class IV antidysrhythmic drugs extensively, assess for any hepatic dysfunction, such as elevated liver enzymes and right upper quadrant abdominal pain.
Adverse effects of sodium nitroprusside include
hypotension, bradycardia, cyanide poisoning, and thiocyanate toxicity.
Calcium channel blockers are metabolized in the liver.It is true that A patient taking a newly prescribed calcium channel blocker states, "I can't seem to get my shoes to fit. My feet feel puffy." Which nursing response is appropriate?
i will contact the healthcare provider, you may need a diuretic
Which type of medication will the nurse most likely administer to prevent organ rejection after a patient has undergone a kidney transplant?
immunosuppressants
Minoxidil adverse effects
include severe rebound hypertension on withdrawal in children, heart failure, pulmonary edema, pericardial effusion, hypotension, and Stevens-Johnson syndrome. When vasodilators are administered, blood pressure decreases, which causes the retention of sodium and water, creating peripheral edema. A diuretic may be prescribed to prevent volume expansion.
Adverse effects of hydralazine
include shock, leukopenia, agranulocytosis, hepatotoxicity, and thrombocytopenia.
A desired effect on the heart from the use of digoxin is
increased myocardial contractility without increasing demands for oxygen (positive inotropic effect).
river blindness
infection of skin and eyes by round worm O. volvulus - can cause blindness - Drug of choice: ivermectin
pediculosis

For a hypertensive crisis, parenteral hydralazine can be
injected to quickly decrease blood pressure.
Minoxidil produces more
intensive vasodilation than hydralazine but also causes more severe adverse reactions. Minoxidil has a black box warning regarding the potential for serious cardiac adverse effects. Sodium nitroprusside has a black box warning regarding the risk for hypotension and cyanide toxicity.
The nurse should recognize that which organ is the most frequent site of helminthic infestation?
intestine
Sodium nitroprusside is an
intravenous (IV), very strong vasodilator, used for hypertensive emergencies. This drug causes venous and arterial dilation and begins to work immediately with IV administration.
The patient must be on a cardiac monitor if administering
intravenous Class IV antidysrhythmic drugs. The nurse administering the drug should be able to see the cardiac monitor to determine the effects of the drug.

Administration of vasodilators requires
ongoing nursing assessment. Some vasodilators, such as sodium nitroprusside, require continuous monitoring in an intensive care setting.
Which route of administration for verapamil is appropriate for maintenance therapy?
oral
Which form of nitroglycerin is likely to have a large first-pass effect?
oral Oral nitroglycerin goes to the liver and is metabolized before it can become active in the body. As a result, a large amount of nitroglycerin is removed from circulation. This is known as a large first-pass effect. Sublingual nitroglycerin has an onset of action of 2 to 3 minutes and is absorbed quickly because the area under the tongue is highly vascular. Transdermal nitroglycerin has an onset of action of 30 to 60 minutes. It is used for long-term management of angina pectoris because it allows for the continuous, slow delivery of nitroglycerin. Intravenous nitroglycerin is quickly absorbed in the blood; it has an onset of action of 1 to 2 minutes.
The preference for digoxin administration is the
oral route. The patient should receive a total of 1 to 1.5 mg orally over the first 24 hours divided into three or four doses. Afterward, the oral maintenance dose should be between 0.125 to 0.5 mg/day. In patients experiencing renal dysfunction or deficiency, the dose should be decreased.
A 57-year-old patient who has osteoporosis after menopause is prescribed 1500 mg of calcium per day and 2000 IU per day of vitamin D for 3 months. After these 3 months, the nurse finds little improvement in the patient's condition. Which assessment finding could be a cause of the patient's condition?
patient smokes and drinks alcohol
Sodium nitroprusside is extremely
potent and can cause excessive hypotension if administered too quickly.
The nurse notes darkened urine of the patient being administered primaquine, as this is a sign of
presence of hemoglobin in the urine and possibly severe hemolysis
The agent of choice for preventing relapse of vivax malaria is
primaquine
The nurse knows this drug would be employed to eradicate P. vivax from the liver, preventing relapse
primaquine
Verapamil excretion
primarily in urine
For digoxin given intravenously, patient safety should be
priority. Proper rate of administration is imperative. Some institutions may require cardiac monitoring during administration of IV digoxin.
The nurse knows that quinine can cause
profound hypoglycemia via stimulation of pancreatic beta cells
Chloroquine is also the drug of choice for
prophylaxis (suppressive therapy)
Which assessment is most important for the nurse to obtain prior to administering digoxin to a patient with heart failure?
pulse It is crucial to measure the patient's pulse before administering digoxin because digoxin causes a decrease in heart rate. In fact, if the heart rate is below 60, digoxin cannot be given. Respiratory rate is not a priority before administration of digoxin because it does not cause respiratory depression. Blood pressure is not as important as pulse because digoxin increases the strength of cardiac contractions. Weight in kilograms is not necessary before administering digoxin.
Which adverse effects would the nurse teach the patient to report during thrombolytic therapy?
rapid heartbeat rashes dizziness lightheadedness
Reflex tachycardia is
reflex stimulation of the heart due to the decrease in blood pressure that causes increased cardiac workload and myocardial oxygen demand. Patients usually receive a beta blocker in combination with hydralazine or minoxidil to prevent reflex tachycardia. Use of hydralazine can also result in an acute rheumatoid syndrome that mimics systemic lupus erythematosus (SLE). Symptoms include fever, joint pain, muscle pain, pericarditis, and nephritis. This most often presents in patients who metabolize the drug slowly; however, it is rare when the dosage is maintained below 200 mg/day. Symptoms are often reversible; however, they can be long lasting (for 6 months or more). An antinuclear antibody (ANA) panel can be used to assess for this side effect.
Which phrases describe reported benefits of prescribing novel oral anticoagulants (NOACs) instead of warfarin?
requent laboratory monitoring is not required for NOACs. Genetics do not alter the effectiveness of NOACs. Comorbid conditions do not affect the effectiveness of NOACs. Diet does not affect the effectiveness of NOACs.
Minoxidil is used in patients who have not responded well to
safer drugs. Minoxidil is indicated for severe hypertension, and it produces a very intense vasodilation. Minoxidil is only added to a drug regimen after maximum therapeutic dosages of a diuretic and two other antihypertensives are used.
Adenosine is contraindicated in patients who have
second- or third-degree heart block, atrial flutter or fibrillation, sick sinus syndrome, or ventricular tachycardia, as well as in those with a known allergy.
Hydralazine works by
selective dilation of arteries and arterioles. It causes the vascular smooth muscle (VSM) to relax, which decreases peripheral resistance and, in turn, lowers blood pressure and decreases afterload. Heart rate and myocardial contractility increase, primarily due to reflex mechanisms.
Grapefruit juice can inhibit metabolism of Class IV antidysrhythmic drugs, raising
serum drug levels with potential toxicity.
Minoxidil is used for
severe hypertension that is unresponsive to other therapy. It has serious adverse effects and is reserved only for patients who have not responded to other safer drugs.
IV quinindine is the treatment of choice for
severe malaria caused by p.vivax and p.falciparum
Which factor in a patient's history is most likely related to the development of Pediculus humanus capitis?
sharing hairbrushes and hats
At a follow-up appointment, a patient who is taking hydralazine for hypertension reports feeling lightheaded and dizzy when standing up. What teaching will the nurse provide?
sit on the edge of the chair and stand up slowly
Which factor should a nurse recognize as one that would increase the risk of thromboembolic phenomena arising from oral contraceptive use?
smoking
The nurse notes significant widening of the QRS complex on ecg for the patient on IV Quinidine Gluconate, the infusion should be
temporarily slowed
Sodium nitroprusside can also cause
thiocyanate toxicity. This is also caused by the metabolism of the drug, and over several days of administration, thiocyanate can accumulate. Symptoms of thiocyanate toxicity include psychotic behavior and delirium. If a patient received sodium nitroprusside for more than 3 days, monitoring of plasma thiocyanate levels is required.
Arteminisinin derivatives are most effective drugs for
treating falciparum malaria (eg artemether and artesunate)
spinosad
treatment of head lice - - more effective than permethrin but more expensive
A patient who is taking sustained-release diltiazem is having difficulty swallowing the medication. What teaching is appropriate?
try taking the medication whole in applesauce or pudding
Diltiazem excretion
urine
crotamiton
used to treat scabies aka Eurex
Intranasal corticosteroids
useful in managing allergic rhinitis.
Verapamil half-life
variable for all routes and formulations
Sodium nitroprusside directly acts on
venous and arterial smooth muscle, producing vasodilation. This decreases peripheral resistance and afterload, increasing cardiac output.
A patient who has begun using transdermal nitroglycerin for angina reports occasional periods of tachycardia. The nurse will expect the prescriber to order: digoxin to slow the heart rate. immediate discontinuation of the nitroglycerin. verapamil as an adjunct to nitroglycerin therapy. periods of rest when the heart rate increases
verapimil as an adjunct to nitroglycerin therapy. (Nitroglycerin lowers blood pressure by reducing venous return and dilating the arterioles. The lowered blood pressure activates the baroreceptor reflex, causing reflex tachycardia, which can increase cardiac demand and negate the therapeutic effects of nitroglycerin. Treatment with a beta blocker or verapamil suppresses the heart to slow the rate. Digoxin is not recommended. Discontinuation of the nitroglycerin is not indicated. Resting does not slow the heart when the baroreceptor reflex is the cause of the tachycardia.)
What will the nurse monitor to evaluate the effectiveness of antiviral agents administered to treat human immunodeficiency virus infection?
viral load All antiretroviral agents work to reduce the viral load, which is the number of viral RNA copies per milliliter of blood. While the other labs may be monitored at one time or another depending on the other medications used or patient condition, the most relevant answer to the effectiveness of the antiretroviral medication is the viral load.
Diltiazem absorption
well absorbed with oral administration
Verapamil absorption
well absorbed with oral administration
Patients who take anticoagulant, antiplatelet, and thrombolytic drugs are at risk for bleeding?
ys
Which lipid parameters would a nurse expect to be reduced with niacin?
Triglycerides Lipoprotein Total cholesterol Low-density lipoprotein (LDL) cholesterol
Which parameters are expected to decrease with statins?
Triglycerides Total cholesterol Apolipoprotein Low-density lipoprotein (LDL) cholesterol
Which non-nucleoside reverse transcriptase inhibitors (NNRTIs) can cause central nervous system (CNS) effects? Select all that apply.
Two of the NNRTIs, efavirenz and rilpivirine, can both cause CNS effects. Etravirine, delavirdine, and nevirapine do not have central nervous system (CNS) effects.
Which parameter would the nurse follow when administering adenosine to a patient to treat supraventricular tachycardia?
Undiluted and rapidly over 1 to 2 seconds as close to the heart as possible Adenosine should be administered undiluted as rapidly as possible over 1 to 2 seconds as close to the heart as possible, such as the antecubital fossa. It is then followed immediately with 20 mL of normal saline flush.
Minoxidil excretion
Urine and feces
Which data would the nurse monitor to evaluate therapeutic effectiveness of desmopressin therapy? Pain scale Blood glucose Blood pressure Urine output
Urine output
IV Administration for digoxin
Use digoxin immediately. Should give IV slowly over a minimum of 5 minutes. May administer undiluted or diluted with a minimum of fourfold volume of sterile water for injection or D5W. Using less than four times dilution may result in drug precipitation.
The nurse administers intravenous desmopressin at 0730. During which time frame would the nurse anticipate giving another dosage of this drug? 0830 to 1030 1000 to 1200 1530 to 1930 0730 the next day
1530 to 1930
A 25-year-old female patient is being discharged from the hospital on valsartan after a hypertensive crisis. Which information would the nurse include in the discharge teaching?
"Be sure to change positions slowly, especially when you get up in the morning." "Take your blood pressure at home to evaluate effectiveness of the medication." "Use contraceptives while taking valsartan."
A patient who has hypertension and asthma asks, "Why can't I take a beta blocker for my hypertension?" Which nursing response is appropriate?
"Beta blocker medications can cause bronchospasm, which can trigger an asthma attack." Nonselective beta blockers have effects on beta1 and beta2 receptors and can cause bronchospasm, so they are contraindicated in patients who have asthma. Cardioselectivity of beta1 blockers does not confer absolute protection from bronchoconstriction, so these drugs are not recommended.
A patient who is being discharged on diltiazem tells the nurse that cooking with herbs and taking supplements has improved the patient's physical stamina. Which response by the nurse is appropriate?
"Certain supplements can alter the therapeutic effects of diltiazem." The nurse would provide teaching on drug-drug, drug-herb, and drug-food interactions. Grapefruit juice, ginkgo, ginseng, hawthorn, and St. John's wort could increase the drug level of diltiazem, increasing the risk of side or adverse effects. The patient should consult with the health care provider or pharmacist before consuming any herb.
Which should the nurse include in a teaching plan for a patient receiving digoxin therapy?
"Digoxin toxicity can cause dysrhythmias." Digoxin toxicity can mimic practically all types of dysrhythmias. Varying degrees of atrioventricular (AV) block are among the most common. Ventricular flutter and ventricular fibrillation are the most dangerous. Digoxin causes dysrhythmias by increasing automaticity in the atria, ventricles, and His-Purkinje system, and by decreasing conduction through the AV node. With proper treatment, digoxin-induced dysrhythmias can almost always be controlled.
Which instruction should the nurse provide when teaching a patient to mix regular insulin and neutral protamine Hagedorn (NPH) insulin in the same syringe?
"Draw up the clear regular insulin first, followed by the cloudy NPH insulin." To ensure a consistent response, only NPH insulin is appropriate for mixing with a short-acting insulin. Unopened vials of insulin should be refrigerated; current vials can be kept at room temperature for up to 1 month. Drawing up the regular insulin into the syringe first prevents accidental mixture of NPH insulin into the vial of regular insulin, which could alter the pharmacokinetics of subsequent doses taken out of the regular insulin vial. NPH insulin is a cloudy solution, and it should always be rotated gently to disperse the particles evenly before loading the syringe. Subcutaneous injections should be made using one region of the body (eg, the abdomen or thigh) and rotated within that region for 1 month.
The clinical coordinator instructs the nursing student to care for a patient with malaria. Which information should the clinical coordinator provide regarding pharmacologic management of malaria?
"Drug resistance can be found in the malarial patient."
The nurse is explaining to a patient the way that hydralazine lowers blood pressure. Which nursing statement is appropriate?
"Hydralazine lowers peripheral vascular resistance, which lowers blood pressure."
Which statements made by the patient indicate a need for more teaching about dronedarone?
"I can take this without regard to food." "If I forget to take a dose, I can double it." "It is normal to develop swelling to the feet."
Teaching is provided to a patient who is prescribed metoprolol after a myocardial infarction. Which response by the patient indicates a need for additional teaching?
"I do not need to check my heart rate before taking the drug." Metoprolol is a beta blocker and can lower the heart rate. This patient requires additional teaching.
The patient refuses to take metoprolol because of its effects on the lungs. The nurse explains that metoprolol will not affect the lungs because it affects which type of cell receptors?
Beta1
A patient was started on intravenous (IV) heparin at 1200 pm. When will the nurse assess the activated thromboplastin time (aPTT)?
1800 aPTT should be assessed 4 to 6 hours after the initiation of heparin to ensure adequate dosing. Values should be 1.5 to 2 times that of the patient's baseline.
In the failing heart, arterial pressure falls, stimulating the baroreceptor reflex to increase sympathetic nervous system activity. The nurse understands increased sympathetic activity will produce which response? 1 Bradypnea 2 Tachycardia 3 Hypotension 4 Hypoglycemia
2
Which statement by Mr. Torres indicates an understanding of the possible side effects of adenosine?
"I might feel some chest pressure, but it will not last long." The patient might experience brief chest pressure with adenosine. Other symptoms the patient may feel include nausea, lightheadedness, head or neck pain, or shortness of breath because of the brief periods of asystole. Because the half-life is less than 10 seconds, these symptoms should resolve quickly.
A patient is being discharged on extended-release (ER) metoprolol. Which statement by the patient indicates an understanding of metoprolol ER?
"I should take the drug whole." Metoprolol ER should be taken whole, without crushing or chewing the medicine.
A nurse is preparing quinidine to administer to a patient with ventricular dysrhythmia. Which dose of quinidine would cause the nurse to notify the health care provider before administering?
100 mg every 4 hours The usual dose for quinidine is 324 to 648 mg every 8 to 12 hours. This dose is too low, and the nurse would be expected to notify and discuss with the health care provider before administering the drug.
The nurse is administering valsartan to a patient with hypertension at 0800. Based on the onset of the drug, at which time will the nurse anticipate an effect on the patient's blood pressure?
1000
The nurse is administering an intravenous (IV) dose of digoxin at 1130. At which time would the nurse anticipate the onset of the drug?
1140 The nurse would anticipate the onset at 1140 because the onset of IV digoxin is 5 to 30 minutes.
The nurse administered a dose of lisinopril at 0800, and the patient's blood pressure was 189/96 mm Hg. Based on the pharmacodynamics of the drug, at which time would the nurse anticipate the greatest reduction in blood pressure?
1400
The nurse administered a dose of lisinopril at 0800, and the patient's blood pressure was 189/96 mm Hg. Based on the pharmacodynamics of the drug, at which time would the nurse anticipate the greatest reduction in blood pressure?
1400 At 1400, the nurse would anticipate peak effects of the drug, as this is 6 hours after administration, and the peak effect occurs within 6 to 8 hours.
The nurse administered a dose of lisinopril at 0800, and the patient's BP was 189/96 mmHg. Based on the pharmacodynamics of the drug, at what time would the use anticipate the greatest reduction in blood pressure?
1400 (At 1400, the nurse old anticipate peak effects of the drug, as this is 6 hours after administration, and the peak effect occurs within 6 to 8 hours. )
For which patients is the use of an angiotensin-converting enzyme (ACE) inhibitor contraindicated? A. 32 year-old female patient who is 4 months pregnant B. 62 year-old male patient with a history of renal artery stenosis c. 56 year-old male patient with a history of coronary artery disease D. 29 year-old female patient with a potassium level of 5.2mEq/L E. 36 year-old patient with type 1 Diabetes mellitus (Choose all that apply)
A,B,C -contraindicated in pregnancy - contraindicated with renal artery stenosis - indicated with high serum potassium
The nurse is teaching a class on angiotensin receptor blockers (ARBs). What would the nurse include in the teaching? A. ARBs lower blood pressure by preventing vasoconstriction B. ARBs prevent angiotensin Il from stimulating the release of aldosterone C. ARBs inhibit the conversion of angiotensin 1 to angiotensin 11 D. ARBs are generally well absorbed E. valsartan crosses the placenta and can cause fetal death F. ARBs can prevent angiotensin 11 from inducing structural changes to the heart (Choose all that apply)
A,B,D,E,F
The nurse is providing education to a patient who is being discharged on valsartan. Which patient responses indicate that more education is required? A. "Which one of those medications is for my blood pressure." B. "I take it at about the Same time each day." C."I have to take it with food or it won't work" D. "I take it only when my BP is over 180/80 mmHg" E. "I will immediately call 911 or my healthcare provider if my face begins to swell."
A,C,D
The nurse is teaching a course on the mechanism of action of angiotensin-converting enzyme (ACE) inhibitors. Which teaching will the nurse include?
ACE inhibitors suppress conversion of angiotensin I to angiotensin II
A patient in a hypertensive crisis is being started on a continuous sodium nitroprusside [Nipride] infusion. Which interventions are essential before the nurse administers nitroprusside [Nipride]? (Select all that apply.) A. Obtain a baseline weight and weigh daily. B. Prepare for arterial line insertion. C. Discontinue the infusion when blood pressure is controlled. D. Observe for signs of hypertrichosis during the infusion. E. Cover the solution with an opaque bag.
A. Obtain a baseline weight and weigh daily. B. Prepare for arterial line insertion. E. Cover the solution with an opaque bag. A Nipride infusion is ordered in micrograms/kilogram/minute. Knowing the patient's weight is essential for calculating the appropriate dose. Also, tracking daily weights and comparing them with the baseline values helps the nurse determine whether the adverse effect of fluid retention has developed. An arterial line allows for continuous and accurate measurement of blood pressure. Because light degrades nitroprusside, the infusion solution should be covered. The infusion should not be discontinued abruptly, because the blood pressure will return to the pretreatment levels within minutes. Hypertrichosis (excessive hair growth) is a side effect of minoxidil.
IV Incompatibilities of adenosine
Adenosine is incompatible with all drugs. It is incompatible with all solutions, except the following: 0.9% NaCl, D5W, Ringer's lactate, or abciximab.
Adenosine
Adenosine is the drug of choice for treating paroxysmal supraventricular tachycardia (PSVT). PSVT begins in an area above the ventricles with the heart rate often exceeding 150 beats/min.
C (The only therapeutic indication of use for adenosine is the treatment of PSVT.)
Adenosine is used to treat which condition? Atrial fibrillation Atrial flutter Paroxysmal supraventricular tachycardia (PSVT) Second-degree atrioventricular block
A patient remains in supraventricular tachycardia after administration of adenosine 6 mg. Which action would the nurse anticipate taking?
Administer adenosine 12 mg in 1 to 2 minutes after the previous dose.
A patient remains in supraventricular tachycardia after administration of adenosine 6 mg. Which action would the nurse anticipate taking?
Administer adenosine 12 mg in 1 to 2 minutes after the previous dose. If the patient is does not respond to the first dose of adenosine within 1 to 2 minutes, then the nurse would prepare to administer adenosine 12 mg.
A patient is prescribed clopidogrel and aspirin at 9:00 a.m. Which action would the nurse take?
Administer both drugs at 0900
What is the nurse's best action when finding a patient with type 1 diabetes mellitus unresponsive, cold, and clammy? Administer subcutaneous regular insulin immediately. Administer glucagon. Start an insulin drip. Draw blood glucose level and send to the laboratory.
Administer glucagon Glucagon stimulates glycogenolysis, raising serum glucose levels. The patient is showing signs of hypoglycemia.
Which action related to drug administration will a nurse expect to take for a patient with unstable ventricular tachycardia?
Administer initial intravenous dose of amiodarone over 10 minutes.
The nurse admits a patient newly diagnosed with schizophrenia to the inpatient mental health unit. What is the priority reason for why the nurse includes the family when collecting the nursing history? A)The patient may not be able to provide a coherent history. B)The patient may not be able to speak due to reduced level of consciousness. C)The family will feel better if they are included in the process. D)The patient will be less anxious if the family listens while he answers questions.
Ans:A Feedback: Schizophrenia, the most common psychosis, is characterized by delusions, hallucinations, and inappropriate responses to stimuli. As a result, the patient may be unable to provide a coherent history and may be unaware of his behaviors considered dysfunctional. There is no reason to suspect the patient cannot speak and reducing anxiety is not the priority rationale for including family. While family is included in treatment, the goal is to treat the patient and not make the family feel better if actions were not in the patient's best interests.
56.For what reason might the nurse administer sildenafil to a woman? A)Pulmonary arterial hypertension B)Sexual dysfunctionC)Breast cancerD)Endometriosis
Ans:A Feedback: Sildenafil is used to treat erectile dysfunction in the presence of sexual stimulation in men and to treat pulmonary arterial hypertension in women. It is not used for sexual dysfunction, breast cancer, or endometriosis in women.
A patient has been diagnosed with roundworms and is to be treated with albendazole. A priority nursing assessment of this patient would be to determine if the patient is taking what? A)Cimetidine (Tagamet) B)Pioglitazone (Actos) C)Alprazolam (Xanax) D)Loperamide (Imodium)
Ans:A Feedback: The adverse effects of albendazole, which are already severe, may increase if the drug is combined with dexamethasone, praziquantel, or cimetidine. These combinations should be avoided if at all possible; if they are necessary, patients should be monitored closely for the occurrence of adverse effects. Pioglitazone is an oral antidiabetic agent that could be taken with albendazole. Loperamide is an antidiarrheal drug that may be used for treatment of diarrhea as a result of the mebendazole and pyrantel. Alprazolam should not be a concern.
The patient's anterior pituitary hormone secretion is impacted by time of day and activity level, which the nurse assesses as what? A)Diurnal rhythm B)Physiological rhythm C)Circadian rhythm D)Biannual rhythm
Ans:A Feedback: The anterior pituitary hormones are released in a rhythmic manner into the bloodstream. Their secretion varies with time of day (often referred to as diurnal rhythm) or with physiological conditions, such as exercise or sleep. A biannual rhythm would be twice a year. Circadian rhythm is indicated by when the patient prefers to sleep or wake, such as those who describe themselves as "morning people." There is no such thing as a physiological rhythm.
What organ should the nurse recognize as the coordinating center for the nervous and endocrine responses to internal and external stimuli? A)Hypothalamus B)Pituitary gland C)Thyroid gland D)Parathyroid gland
Ans:A Feedback: The hypothalamus is the coordinating center for the nervous and endocrine responses to internal and external stimuli. The pituitary, thyroid, and parathyroid glands all play an important role in maintaining homeostasis, but they do not connect the nervous and endocrine systems.
A child was diagnosed with attention-deficit hyperactivity disorder and methylphenidate was prescribed for treatment to be taken once a day in a sustained release form. On future visits what is a priority nursing assessment for this child? A)Weight and height B)Breath sounds and respiratory rate C)Urine output and kidney function D)Electrocardiogram (ECG) and echocardiogram
Ans:A Feedback: The nurse needs to carefully track this child's weight and height because the drug can cause weight loss, anorexia, and nausea that could result in slowed or absent growth. There would be no need to monitor breath sounds, respiratory rate, urine output, and kidney function. Although arrhythmias may occur as an adverse effect necessitating an ECG, there is no need to perform echocardiograms.
A 68-year-old male patient tells the nurse that he has been unable to get an erection for the past 6 months and he guesses his sex life is over. The provider orders diagnostic testing to determine whether sildenafil (Viagra) is appropriate for the patient. What is the most correct nursing diagnosis for this patient? A)Sexual dysfunctionB)Disturbed body imageC)Ineffective sexuality pattern D)Disturbed tactile sensory perception
Ans:A Feedback: The patient is experiencing sexual dysfunction so that would be the most appropriate nursing diagnosis. The patient did not discuss feeling let down by or unhappy with his body so disturbed body image is incorrect. The effectiveness of sexual pattern is not known. No problem with sensory perception is indicated by this question.
A patient on the unit has a deep decubitus ulcer. The family asks why the nurse debrides the ulcer and removes the dead cells. What is the nurse's best response to explain to the family why debridement is performed? A)The lysosomes released by the dead cells in the area continue to kill other cells, destroying more tissue. B)The dead cells no longer contain histocompatible antigens causing a greater inflammatory response. C)Removing dead tissue forces oxygen to enter the damaged cells to regenerate them and to promote healing. D)The doctor ordered the procedure to be performed so it is done the way it is ordered because orders are always followed.
Ans:A Feedback: When a cell dies, its cell membrane ruptures and the lysosomes release lysozymes, which dissolve protein. When many cells die, lysozymes accumulate and dissolve the proteins that the dead cells leave behind, but the lysozymes also destroy the cell membrane of healthy cells in the area. Those cells then die, releasing lysozymes, which destroy more cells, and a vicious cycle occurs. A decubitus ulcer is an area of many dead cells, which are killing healthy cells. The area needs to be scraped clean to remove the dead cells so that the lysozymes will stop destroying healthy cells and allow oxygen to return to the area through the capillary bed, which allows healing to occur. Many treatments exist for decubitus ulcers, all of which depend on the return of blood flow to the area and removal of the dead tissue. No procedure should ever be performed only because it was ordered. The nurse should understand why each procedure is needed.
What is an appropriate nursing diagnosis for a patient with tapeworm? A)Imbalanced nutrition: less than body requirements B)Chronic pain C)Constipation D)Impaired mobility
Ans:A Feedback:Tapeworm affects the body's ability to absorb food products and weight loss and malnutrition often follow unless treatment is received promptly. As a result, the best nursing diagnosis is imbalanced nutrition: less than body requirements. Patients with tapeworm are often symptom-free but may experience some abdominal discomfort and distention as well as weight loss so they do not have chronic pain, constipation, or impaired mobility.
The mother of a child diagnosed with attention-deficit syndrome receives a prescription for a central nervous system (CNS) stimulant to treat her child. The mother asks the nurse, "I don't understand why we're giving a stimulant to calm him down?" What is the nurse's best response to this mother? A)"It helps the reticular activating system (RAS), a part of the brain, to be more selective in response to incoming stimuli." B)"It helps energize the child so they use up all of their available energy and then they can focus on quieter stimuli." C)"No one truly understands why it works but it has been demonstrated to be very effective in treating ADHD." D)"The drugs work really well and you will see a tremendous change in your child within a few weeks without any other treatment."
Ans:A Feedback: The paradoxical effect of calming hyperexcitability through CNS stimulation seen in attention-deficit syndrome is believed to be related to increased stimulation of an immature RAS, which leads to the ability to be more selective in response to incoming stimuli. CNS stimulants do not cause the child to use all his energy, the effect is thought to be understood, and telling the mother the drug just works without any explanation is not appropriate and may result in noncompliance with pharmacology therapy if the mother does not understand why the drug is given.
The nurse is caring for an older adult in the long-term care facility who has begun to display signs of anxiety and insomnia. What is the priority nursing action? A)Assess the patient for physical problems. B)Call the provider and request an antianxiety drug order. C)Increase the patient's social time, encouraging interaction with others. D)Suggest the family visit more often to reduce the resident's stress level.
Ans:A Feedback: The patient should be screened for physical problems, neurological deterioration, or depression, which could contribute to the insomnia or anxiety. Only after physical problems are ruled out would the nurse consider nondrug measures such as increased socialization with other residents or family members. If nothing else is effective, pharmacological intervention may be necessary.
The nurse is caring for a pregnant patient. What hormone must be secreted to cause uterine contractions? A)Oxytocin B)ADHD C)Estrogen D)Enkephalins
Ans:A Feedback: The pituitary is made up of three lobes: anterior, intermediate, and posterior. The posterior lobe stores two hormones produced by the hypothalamus, ADH and oxytocin. Oxytocin stimulates uterine smooth muscle contraction in late phases of pregnancy and also causes milk release or "let down" reflex in lactating women. The posterior lobe does not store estrogen or enkephalins. ADHD (i.e., attention deficit hyperactivity disorder is a disease process, not a hormone.
The pharmacology instructor is discussing adrenergic agonists with the nursing class. Which drugs would the instructor tell the nursing students are generally indicated for the treatment of shock, bronchospasm, and some types of asthma? A)Sympathomimetic drugs B)Beta-blocking drugs C)Parasympathetic stimulating drugs D)Anticatecholamine drugs
Ans:A Feedback: These drugs generally are indicated for the treatment of hypotensive states or shock, bronchospasm, and some types of asthma. Beta-blocking drugs, parasympathetic stimulating drugs, and anticatecholamine drugs are not the drugs of choice in these situations.
A 4-year-old is admitted to the emergency department in shock after a motor vehicle accident. The patient weighs 12.5 kg. What would be the minimum safe dose of adrenalin if the pediatric dose is 0.005 to 0.01 mg/kg IV? A)0.0625 mg B)0.075 mg C)0.08 mg D)0.085 mg
Ans:A Feedback: To calculate the minimum dosage, multiply the child's weight in kg by the lower dosage range; 12.5 × 0.005 = 0.0625 mg.
What would be important for the nurse to teach the parents of a pediatric patient about the use of topical corticosteroids? A)"Apply the medication sparingly." B)"Apply directly to open lesions." C)"After applying cover with a bandage." D)"Reapply as often as needed to keep the rash coated with the medication."
Ans:A Feedback: Topical use of corticosteroids should be limited in children, because their body surface area is comparatively large, so that the amount of the drug absorbed in relation to weight is greater than in an adult. Apply sparingly and do not use in the presence of open lesions. Do not occlude treated areas with dressings or diapers, which may increase the risk of systemic absorption.
The 22-year-old patient tells the nurse he doesn't have trouble obtaining and maintaining an erection but wonders if taking Viagra would improve the sexual experience anyway. What is the nurse's best response? A)"The only thing Viagra does is improve blood flow to the penis to make it erect." B)"Viagra improves stamina and sensation, making the sexual experience better." C)"Viagra has its greatest effect if both the man and woman take it at the same time." D)"Viagra does nothing to improve the sexual experience."
Ans:A Feedback: Viagra improves blood flow into the penis and that is its only effect. It does not improve stamina or sensation. Research has indicated it has no effect on women's sexual response. To say only that Viagra does nothing would not provide adequate information for the patient.
The nurse is teaching the patient who will require long-term corticosteroid therapy how to reduce the risk of infection. What suggestions will the nurse include? A)"Avoid large crowds of people tightly packed together." B)"Avoid working in areas with other people." C)"Avoid exercising to reduce risk of injury." D)"Avoid touching other people who may carry germs."
Ans:A Feedback: With long-term therapy, the importance of avoiding exposure to infection—crowded areas, people with colds or the flu, activities associated with injury—should be stressed. If an injury or infection should occur, the patient should be encouraged to seek medical care. These patients do not need to avoid work, exercise, or touching others but they should use good hand hygiene to avoid infection from these sources.
The nurse is caring for a patient who received a new diagnosis of cancer. The patient exhibits signs of a sympathetic stressreaction. What signs and symptoms will the nurse assess in this patient consistent with an acute reaction to stress? (Select all that apply.) A)Profuse sweatingB)Fast heart rateC)Rapid breathing D)HypotensionE)Inability to interact with others
Ans:A, B, C Feedback: Anxiety is often accompanied by signs and symptoms of the sympathetic stress reaction that may include sweating, fast heart rate, rapid breathing, and elevated blood pressure. Chronically anxious people may be afraid to interact with other people but this is not usually seen in an acute stress reaction.
A nurse would anticipate that which dysrhythmia will likely develop when adenosine is administered?
Asystole
A nursing student asks the pharmacology instructor for ways to minimize the emergence of drug-resistant microbial agents. What would be an appropriate response by the instructor? (Select all that apply.) A)Avoid the use of broad-spectrum antibacterial drugs when treating trivial or viral infections. B)Use narrow-spectrum agents if they are thought to be effective. C)Do not use vancomycin unnecessarily. D)Prescribe antibiotics when the patient believes they are warranted. E)Start the antibiotics, do culture and sensitivity tests, and provide patient education.
Ans:A, B, C Feedback: To prevent or contain the growing threat of drug-resistant strains of bacteria, it is very important to use antibiotics cautiously, to complete the full course of an antibiotic prescription, and to avoid saving antibiotics for self-medication in the future. You would not give antibiotics every time the patient wants them, nor would you do a culture and sensitivity test after starting antibiotics. Therefore, Options D and E are incorrect.
The nurse assesses the patient who had an abrupt withdrawal of benzodiazepines for withdrawal syndrome and would recognize what symptoms as part of the syndrome? (Select all that apply.) A)Headache B)Nightmares C)Malaise D)Bradycardia E)Hypotension
Ans:A, B, C Feedback: Abrupt cessation of benzodiazepines may lead to a withdrawal syndrome characterized by nausea, headache, vertigo, malaise, and nightmares. Withdrawal symptoms may be caused by the abrupt separation of benzodiazepine molecules from their receptor sites and the resulting acute decrease in gamma-aminobutyric acid (GABA) neurotransmission. Because GABA is an inhibitory neurotransmitter, less GABA may produce a less inhibited central nervous system (CNS) and therefore symptoms of hyperarousal or CNS stimulation. The nurse would not categorize hypotension or bradycardia as indicating benzodiazepine withdrawal.
The nurse is giving discharge instructions to a patient who just had Botox A injections around her eyes. What adverse effects would the nurse include in her discharge instructions? (Select all that apply.) A)Respiratory infections B)Flu-like syndrome C)Droopy eyelids D)Cough E)Diarrhea
Ans:A, B, C Feedback: Adverse effects associated with use of botulinum toxin type A for cosmetic purposes include headache, respiratory infections, flu- like syndrome, and droopy eyelids in severe cases. Adverse effects do not include cough or diarrhea.
When studying for a pharmacology exam, a student asks her peers which agents affect both alpha- and beta-receptor sites. What would be an appropriate response to this student? (Select all that apply.) A)Dobutamine (Dobutrex) B)Epinephrine (Adrenalin, Sus-Phrine) C)Dopamine (Intropin)D)Clonidine (Catapres)E)Albuterol (Proventil)
Ans:A, B, C Feedback: Agents that affect both alpha- and beta- receptor sites include dobutamine, dopamine, ephedrine, epinephrine, and norepinephrine. Clonidine is an alpha-specific adrenergic agonist; albuterol is a beta-specific adrenergic agonist.
When making a presentation on the cell, what would the students say are the main parts of the cell? (Select all that apply.) A)The nucleusB)The cytoplasm C)The cell membrane D)The mitochondria E)The organelles
Ans:A, B, C Feedback: The cell is composed of a nucleus, which contains genetic material and controls the production of proteins by the cell; a cell membrane, which separates the inside of the cell from the outside environment; and cytoplasm, which contains various organelles important to cell function. The mitochondria and the organelles are units within the cytoplasm but are not main parts of the cell.
The nurse is caring for a patient who has been taking androgens and has been admitted to the ICU following a car accident. What lab results will the nurse interpret as more indicative of androgen therapy than actual disease states? (Select all that apply.) A)Decreased thyroid functionB)Increased creatinine levelsC)Increased creatinine clearance D)Elevated liver enzymesE)Increased white blood cell (WBC) count
Ans:A, B, C Feedback: While a patient is taking androgens, thyroid function may be decreased, as well as increased creatinine and creatinine clearance, results that are not associated with disease states. These effects can last up to 2 weeks after the discontinuation of therapy. Elevated liver enzymes may indicate a potentially life- threatening effect that has been documented is hepatocellular cancer. Increased WBC count would indicate an infection. Increased liver enzymes and WBC are not associated with androgen therapy but instead indicate a disease state.
The nurse is teaching a class for nurses working in prenatal clinics about the danger associated with use of benzodiazepines during pregnancy and explains that what fetal anomalies result from maternal use of benzodiazepines during the first trimester of pregnancy? (Select all that apply.) A)Cleft lip or palate B)Inguinal hernia C)Cardiac defects D)Microencephaly E)Gastroschises
Ans:A, B, C, D Feedback: Benzodiazepines are contraindicated in pregnancy because a predictable syndrome of cleft lip or palate, inguinal hernia, cardiac defects, microcephaly, or pyloric stenosis occurs when they are taken in the first trimester. Gastroschises, when the abdominal organs are found outside the abdominal cavity, is not associated with use of benzodiazepine use in the first trimester.
The nurse assesses the young adult athlete who has been taking anabolic steroids to enhance his performance. What findings would the nurse associate with this practice? (Select all that apply.) A)Personality changes B)Sexual dysfunction C)Increased serum lipid levels D)Cardiomyopathy E)Weight loss
Ans:A, B, C, D Feedback: Cardiomyopathy, hepatic carcinoma, personality changes, and sexual dysfunction are all associated with the excessive and off- label use of anabolic steroids for athletic performance enhancement. Adverse effects associated with prescription use include inhibition of testicular function, gynecomastia, testicular atrophy, priapism, baldness, change in libido, serum electrolyte changes, liver dysfunction, insomnia, and weight gain, not weight loss.
What reasons can the nurse give for why barbiturates are no longer considered the mainstay for treatment of anxiety? (Select all that apply.) A)Adverse effects are more severe. B)There is an increased risk of physical tolerance. C)There is an increased risk of psychological dependence. D)The most common adverse effects are related to cardiac arrhythmias. E)Hypersensitivity reactions can sometimes be fatal.
Ans:A, B, C, E Feedback: The adverse effects caused by barbiturates are more severe than those associated with other, newer sedatives/hypnotics. For this reason, barbiturates are no longer considered the mainstay for the treatment of anxiety. In addition, the development of physical tolerance and psychological dependence is more likely with the barbiturates than with other anxiolytics. The most common adverse effects are related to central nervous system (CNS) depression. Hypersensitivity reactions to barbiturates are sometimes fatal.
The nurse is preparing to contact the physician for an antibiotic order for the patient's infection. What information will the nurse be prepared to provide for the physician to choose the proper antibiotic? A)First day of infection symptoms B)Culture and sensitivity test results C)The patient's intake and output for past 2 days D)Results of complete blood count with differential
Ans:B Feedback: Antibiotics are best selected based on culture results that identify the type of organism causing the infection and sensitivity testing that shows what antibiotics are most effective in eliminating the bacteria. First day of symptoms of infection is likely already known if culture and sensitivity testing has been performed. Although measurement of intake and output is one indicator of renal function, a blood-urea-nitrogen test and assessment of creatinine levels would be better ways of assessing renal function, which will be used to determine dose of medication but not for selection of the correct antibiotic. The white blood cell count and differential would indicate the possibility of an infection but are not needed in choosing the proper antibiotic.
The nurse, providing teaching about a typical antipsychotic newly prescribed for the patient, cautions against use of alcohol with the drug by explaining it will have what effect? A)Prolonged QT interval B)Increased central nervous system (CNS) depression C)Increased anticholinergic effects D)Increased gastrointestinal (GI) adverse effects
Ans:B Feedback: Antipsychotic-alcohol combinations combinations result in an increased risk of CNS depression, and antipsychotic- anticholinergic combinations lead to increased anticholinergic effects, so dosage adjustments are necessary. Patients should not take thioridazine or ziprasidone with any other drug associated with prolongation of the QT interval. Increase in GI adverse effects is not associated with concurrent use of alcohol.
A 28-year-old patient has been prescribed penicillin for the first time. What nursing diagnosis would be most appropriate for this patient? A)Acute pain related to gastrointestinal (GI) effects of the drug B)Deficient knowledge regarding drug therapy C)Imbalance nutrition: less than body requirements related to multiple GI effects of the drug D)Constipation
Ans:B Feedback: Because this is the first time the patient has taken penicillin, she is likely to have limited knowledge about the drug. She may not understand the importance of taking the medication as ordered to increase effectiveness of the drug or to report adverse effects. because the patient has not started the drug yet, there is no way to know what adverse effects, if any, she will experience. Only if she develops acute pain related to GI effects of the drug would this be appropriate. If GI symptoms develop it may lead to imbalanced nutrition, but that remains to be seen. No indication about constipation exists.
The 63-year-old male patient receives a prescription for androgens. The nurse evaluates that the patient understood drug teaching when he makes what statement? A)"If I experience acne, I will contact my physician immediately." B)"If I experience flushing, sweating, nervousness, or emotional lability I'll know it's the drug." C)"I will report any difficulty urinating such as trouble starting my flow." D)"These pills may make my skin turn yellow but it will go away when the drug is stopped."
Ans:B Feedback: Benign prostatic hypertrophy, a common problem in older men, may be aggravated by androgenic effects that may enlarge the prostate further, leading to urinary difficulties and increased risk of prostate cancer. Nurses should teach these men the signs and symptoms of prostatic enlargement and the importance of reporting these manifestations immediately to prevent worsening of symptoms. Acne need not be reported immediately. Flushing, sweating, nervousness, and emotional lability are more usually experienced by women. Yellowing of the skin may be an indication of liver disease, which should be reported immediately
The nurse is caring for a patient who has a sedative hypnotic ordered. The nurse would consider this drug contraindicated if the patient had what disorder? A)Neurological diseases B)Liver failure C)Endocrine disorders D)Heart disease
Ans:B Feedback: Benzodiazepines undergo extensive hepatic metabolism. In the presence of liver disease, the metabolism of most benzodiazepines is slowed, with resultant accumulation and increased risk of adverse effects. Neurological disorders, endocrine disorders, and heart disease are not contraindications for the use of benzodiazepines.
A young woman attends a "Botox Party" and is injected with botulinum toxin type A to decrease "frown lines" between her eyebrows. Later that evening the patient is admitted to the emergency department and is hysterical, because she cannot move her eyebrows. The nurse explains that that toxin causes what? A)"The toxin causes muscle death, which smoothes wrinkles in the area." B)"The toxin causes muscle paralysis, preventing movement and relieving wrinkles." C)"The drug is a toxin to nerves in the area." D)"The drug is a permanent muscle relaxant and the muscles will never move again."
Ans:B Feedback: Botulinum toxin types A and B bind directly to the receptor sites of motor nerve terminals and inhibit the release of acetylcholine, leading to local muscle paralysis. These two drugs are injected locally and used to paralyze or prevent the contractions of specific muscle groups. The action smoothes wrinkles in the area, but does not cause muscle death. The effect is temporary and does not cause nerve death. The other options are false statements.
When compared with benzodiazepines, buspirone (BuSpar) stands out as unique among antianxiety drugs because of what factor? A)Increases the central nervous system (CNS) depression of alcohol and other drugs. B)Lacks muscle relaxant and anticonvulsant effects. C)Causes significant physical and psychological dependence. D)Rapidly absorbed from the gastrointestinal (GI) tract and metabolized in the liver.
Ans:B Feedback: Buspirone, a newer antianxiety agent, has no sedative, anticonvulsant, or muscle-relaxant properties, and its mechanism of action is unknown. However, it reduces the signs and symptoms of anxiety without many of the central nervous system effects and severe adverse effects associated with other anxiolytic drugs. Most of the antianxiety drugs are rapidly absorbed from the GI tract, metabolized in the liver, have a significant drug-drug interaction with alcohol and other drugs, and can result in psychological dependence.
The nurse is caring for a patient with abnormal calcium levels. What thyroid hormone does the nurse expect this will impact? A)Aldosterone B)Calcitonin C)Erythropoietin D)Insulin
Ans:B Feedback: Calcitonin is produced and secreted by the thyroid gland in direct response to serum calcium levels. Aldosterone is an adrenocorticoid hormone that is released in response to adrenocorticotropic hormone. Erythropoietin is released by the juxtaglomerular cells in the kidney in response to decreased pressure or decreased oxygenation of the blood flowing into the glomerulus. Insulin is produced by the pancreas in response to varying blood glucose levels.
The pharmacology instructor is explaining to their class the difference between the "typical" and the "atypical" groups of antipsychotic drugs. What medication would the instructor explain to the students has fewer extrapyramidal effects and greater effectiveness than older antipsychotic drugs in relieving negative symptoms of schizophrenia? A)Chlorpromazine (Thorazine) B)Clozapine (Clozaril) C)Thiothixene (Navane) D)Haloperidol (Haldol)
Ans:B Feedback:Advantages of clozapine include improvement of negative symptoms without causing the extrapyramidal effects associated with older antipsychotic drugs. Chlorpromazine is a typical antipsychotic, one of the older drugs, which does cause the extrapyramidal effects. Navane is part of the thioxanthene group of typical antipsychotics. This group of drugs has low sedative and hypotensive effects but can cause extrapyramidal effects. Haloperidol is a butyrophenone group drug used in psychiatric disorders. Usually, it produces a relatively low incidence of hypotension and sedation and a high incidence of extrapyramidal effects.
A patient, who is 77 years old, is admitted with a diagnosis of dementia. Haloperidol (Haldol) has been ordered for this patient. What nursing considerations would govern the nurse's actions? (Select all that apply.) A)It is classed as an atypical antipsychotic. B)A lowered dosage is indicated for older adult. C)It often has a hyperactive effect on patients. D)It should not be used to control behavior with dementia. E)It should only be given every other day.
Ans:B, DFeedback: Haloperidol is classified as a typical antipsychotic with a high risk of extrapyramidal effects and lower risk for hypotension and sedation. Older patients may be more susceptible to the adverse effects of antipsychotic drugs. All dosages need to be reduced and patients monitored very closely for toxic effects and to provide safety measures if central nervous system effects do occur. They should not be used to control behavior with dementia. Haloperidol does not have a hyperactive effect on patients; it should not be given on an every-other-day schedule.
An elderly patient has received a neuromuscular junction blocker during surgery. What would be an appropriate nursing diagnosis for this patient? A)Excess fluid volumeB)Risk for impaired skin integrity C)Deficient fluid volume D)Chronic confusion
Ans:BFeedback: An elderly or frail patient will need extra nursing care to prevent skin breakdown during the period of paralysis because skin tends to be thinner and more susceptible to breakdown. Therefore, risk of impaired skin integrity would be an appropriate nursing diagnosis. Fluid excess or deficit should not be a concern and the patient may be acutely confused when awakening, but there is no reason to think he or she would remain chronically confused if he was not before surgery.
The nurse is caring for a patient diagnosed with a condition resulting in inadequate production of cholecystokinin. What would the nurse expect to find when assessing this patient? A)Elevated serum sodium and reduced serum potassium levels B)Decreased bowel sounds C)Increased numbers of red blood cells D)Increased serum calcium levels
Ans:BFeedback: Cholecystokinin is secreted by the intestine and decreases gastric movement resulting in diminished bowel sounds as well as stimulation of bile and pancreatic juice secretion. Aldosterone causes sodium retention and potassium excretion. Erythropoietin increases red blood cell production. Parathyroid hormone causes an increase in serum calcium levels.
The pharmacology instructor is discussing nondepolarizing neuromuscular junction blockers (NMJ) blockers with the nursing class. How would the instructor explain the action of nondepolarizing NMJ blockers? A)Blocks acetylcholine (ACh) from acting B)Acts like ACh then prevents repolarization C)Takes the place of ACh in the depolarizing/repolarizing process D)Stops depolarization in the axion
Ans:BFeedback: Depolarizing NMJ blockers cause muscle paralysis by acting like ACh. They excite (depolarize) the muscle and prevent repolarization and further stimulation. Options A, C, and D are incorrect.
A 66-year-old female patient is on long-term oral glucocorticoid therapy to treat chronic obstructive pulmonary disease. When providing drug teaching, the nurse will inform this patient that she is at particular risk for what? A)HyponatremiaB)Spontaneous fractures C)Respiratory depression D)Ineffective temperature regulation
Ans:BFeedback: Only spontaneous fractures are considered an adverse effect of glucocorticoids; this patient would be at increased risk because her age and gender put her at higher risk for osteoporosis, which also has the adverse effect of spontaneous fractures. Long-term glucocorticoid therapy is not associated with hyponatremia, respiratory depression, or ineffective temperature regulation.
Some hormones react with specific receptor sites on a cell membrane and stimulate what? A)MeiosisB)Cyclic adenosine monophosphate (cAMP) C)Increase in hormonal inactivity D)Decrease in hormonal activity
Ans:BFeedback: Some hormones react with specific receptor sites on a cell membrane to stimulate the nucleotide cAMP within the cell to elicit an effect. Hormones that react with specific receptor sites do not stimulate miosis, or a change in amount of hormonal activity, either an increase or decrease, which would be regulated by a negative feedback mechanism.
A patient is extremely dehydrated from vomiting and diarrhea causing his or her blood to become hypertonic. What effect does the nurse expect this will have on the red blood cells? A)They will swell and eventually rupture. B)Red blood cells will migrate to the bone narrow. C)The cells will shrink and shrivel, decreasing their oxygen-carrying ability. D)The red cells will precipitate out of circulation.
Ans:C Feedback: A hypertonic solution will draw the water out of the red blood cell, causing it to shrink and shrivel, decreasing the oxygen carrying ability of the red blood cell. A hypotonic solution would result in water moving into the red blood cell, causing it to swell and burst. Red blood cells will not migrate back to the bone marrow or precipitate out of circulation.
The nurse is caring for a patient who is being maintained on mechanical ventilation. Atracurium is administered to limit the resistance to mechanical ventilation. What is the nurse's priority assessment? A)Hypotension B)Tachycardia C)Bradycardia D)Increased secretions
Ans:C Feedback: Bradycardia is a common adverse effect associated with atracurium. The nurse should monitor the patient regularly to avoid serious adverse effects. Increased secretions and hypotension are common with tubocurarine. Option B is a distracter.
Estrogen enters the cell and reacts with a receptor site. What is the final result of this reaction? A)Deoxyribonucleic acid (DNA) is affected. B)Ribonucleic acid enters the cell nucleus. C)Alteration in cellular function D)Changes messenger RNA
Ans:C Feedback: Estrogen enters the cell and reacts with a receptor site inside the cell to change messenger RNA, which enters the cell nucleus to affect cellular DNA, and the final result is an alteration in the cell's function.
A 17-year-old male patient with athlete's foot is extremely upset that he cannot get rid of it. He calls the clinic and asks the nurse whether the doctor can give him an antibiotic to "cure the infection." What should the nurse include in the explanation of treatment for fungal infections? A)"Fungi differ from bacteria in that the fungus has flexible cell walls that allow for free transfer into and out of the cell." B)"Protective layers contain sterols, which change the membrane permeability." C)"The composition of the protective layers of the fungal cell makes the organism resistant to antibiotics." D)"Fungi cell walls contain Candida, which makes the cells rigid.
Ans:C Feedback: The nurse should tell the patient that the composition of the protective layers of the fungal cell makes the organism resistant to antibiotics so that antibiotics would not have any positive effect. Fungi do differ from bacteria, but the fungus has rigid cell walls that allow for free transfer in and out of the cell. The protective layers contain ergosterol, not Candida, that helps keep the cell wall rigid, not permeable.
A nurse receives an order for clonidine (Catapres) for a 25-year-old pregnant woman. What is the nurse's priority action? A)Weigh the patient to obtain correct dose/kg/day. B)Have a second nurse check the dose before administering the drug. C)Consult with the physician about the order. D)Make sure the patient is wearing a fetal monitor.
Ans:C Feedback: The nurse would consult with the physician to ensure awareness of the pregnancy and desire to administer this drug. There are no adequate studies about use during pregnancy and lactation, so use should be reserved for situations in which the benefit to the mother outweighs any potential risk to the fetus or neonate. The nurse should question the prescriber regarding this order. It would not be necessary to implement the other options.
A patient who is using a topical antifungal agent to treat mycosis calls the clinic to report a severe rash that is accompanied by blisters. What will the nurse instruct the patient to do? A)"Continue the drug as the prescription indicates." B)"Scrub the rash with soap and water." C)"Stop using the drug immediately." D)"Decrease the amount of the medication used."
Ans:C Feedback: The patient should stop using the drug. The rash could indicate sensitivity to the drug or worsening of the condition being treated. Scrubbing the rash could cause further irritation and increase the risk for other infections. Continuing the drug could cause further complications. Decreasing the medication would be ineffective in treating the infection while continuing to risk further complications.
When administering a topical antifungal via the vaginal route, what action would the nurse take? A)Place the patient in left lateral Sims' position. B)Applied using sterile technique C)Administered high into the vagina. D)Insert a tampon after insertion.
Ans:C Feedback: Vaginal antifungals should be administered high into the vagina. The patient should be placed in a recumbent position for insertion. Clean technique (not sterile) should be used. Inserting a tampon after administration is not necessary.
The nurse is preparing a patient for surgery who will receive a neuromuscular junction blocker during the procedure. It is important for the nurse to review the patient's medication history for concurrent use of what? A)Angiotensin-converting enzyme (ACE) inhibitors B)Beta blockers C)Calcium channel blockers D)Montelukast
Ans:C Feedback: When calcium channel blockers are used concurrently with neuromuscular junction blockers, the patient is at increased risk of prolonged paralysis. The dose of the neuromuscular junction blocker should be lowered if this combination cannot be avoided and the patient should be monitored closely. There is no anticipated drug-drug interaction with ACE inhibitors, beta blockers, or montelukast.
The nurse is caring for a patient who is diagnosed with protein-deficient malnutrition. Why would an order to administer androgens to this patient be appropriate? A)Androgens reduce the body's requirement for protein. B)Androgens increase the body's absorption of protein from the bowel. C)Androgens stimulate protein production and decrease protein breakdown. D)Androgens reduce carbohydrate metabolism and promote lipid absorption.
Ans:C Feedback: Androgens are a form of the male sex hormone called testosterone. They affect electrolytes, stimulate protein production, and decrease protein breakdown, which will help to reverse the patient's protein malnutrition in addition to a high-protein diet. They do not reduce the body's need for protein, increase protein absorption from the bowel, or impact carbohydrate and lipid metabolism.
The nurse provides teaching about amphotericin B (Fungizone) for an 82-year-old patient. The nurse evaluates the patient understood teaching when he says he could develop what condition? A)Diabetes B)Liver necrosis C)Kidney damage D)Pancreatitis
Ans:C Feedback: Amphotericin B is nephrotoxic so the patient needs to understand the risk of kidney damage. Other risks of amphotericin B include bone marrow suppression; GI irritation with nausea, vomiting, and potentially severe diarrhea; anorexia and weight loss; and pain at the injection site with the possibility of phlebitis or thrombophlebitis, but it does not cause diabetes, liver necrosis, or pancreatitis.
According to the sliding filament theory, what is the initial action in a muscle contraction? A)Troponin is freed and prevents actin and myosin from reacting with each other. B)Calcium binds to troponin, which causes the release of actin and myosin binding sites. C)Actin and myosin molecules react with each other sliding along the filament and making it shorter. D)Muscle filament relaxes or slides back to the resting position.
Ans:C Feedback: Actin and myosin molecules react with each other again and again, sliding along the filament and making it shorter. This is a contraction of the muscle fiber according to the sliding filament theory. As the calcium is removed from the cell during repolarization of the muscle membrane, the troponin is freed and once again prevents the actin and myosin from reacting with each other. The muscle filament then relaxes or slides back to the resting position. Muscle tone results from a dynamic balance between excitatory and inhibitory impulses to the muscle.
The patient is prescribed oxandrolone 2.5 mg twice a day and is told to increase the dosage to gain weight to a maximum of 20 mg/d. If each tablet contains 2.5 mg, how many tablets would the nurse tell the patient he may take per day to avoid exceeding the 20 mg/d maximum? A)4B)6C)8D)10
Ans:C Feedback: Calculate the number of tablets required to administer 20 mg by dividing 20 mg by 2.5 mg. 20/2.5 = 8 tablets
The nurse administers danazol (Danocrine) be a woman for what purpose? A)Reverse folic acid deficiencies B)Increase hair growth C)Decrease symptoms of endometriosis D)Prevent toxic shock syndrome.
Ans:CFeedback: Danazol may be used in women to prevent or treat endometriosis or fibrocystic breast disease. Danazol is not prescribed for increased hair growth, to reverse folic acid deficiencies, or to prevent toxic shock syndrome.
The nurse explains the end result of the hypothalamus in regulating the central nervous system (CNS), autonomic nervous system (ANS), and endocrine system is what? A)Regulation of the negative feedback system B)Creation of a diurnal rhythm C)Maintenance of homeostasis D)Production of prolactin-inhibiting factor (PIF)
Ans:C Feedback: The hypothalamus maintains internal homeostasis by sensing blood chemistries and by stimulating or suppressing endocrine, autonomic, and CNS activity. In essence, it can turn the ANS and its effects on or off. The negative feedback system is one way homeostasis is maintained. When the hypothalamus senses a need for a particular hormone, it secretes a releasing factor directly into an area such as the anterior pituitary. This causes the area to produce a hormone. When the hypothalamus senses a rising level of the hormone it stops secreting the releasing factor, which decreases the hormone production. When this occurs the hypothalamus senses the falling hormone level and the releasing factor is secreted again. This process is how the hormone level is maintained. Diurnal rhythm refers to the release of hormones at various times of the day. PIF, produced by the hypothalamus, acts as a regulator to shut off production of hormones when levels become too high.
A researcher is studying chromosomal disorders. What part of the human cell would the researcher be interested in studying? A)Cytoplasm B)Membrane C)Nucleus D)Organelles
Ans:C Feedback: The nucleus of a cell contains all of the genetic material that is necessary for cell reproduction. The nucleus also contains genes or sequences of deoxyribonucleic acid (DNA). Genes are responsible for the formation of messenger ribonucleic acid (mRNA) and transcription RNA, which are involved in production of proteins unique to the cells. This is the area where chromosomal disorders originate. The cell cytoplasm lies within the cell membrane and is the site of activities of cellular metabolism and special cellular functions. The organelles are contained within the cytoplasm and are structures with specific functions. They include the mitochondria, endoplasmic reticulum, free ribosomes, Golgi apparatus, and lysosomes. The membrane is a thin barrier, which separates the intracellular fluid from the extracellular fluid and is essential for cellular integrity; it also maintains cell homeostasis.
A patient comes to the clinic and is diagnosed with a vaginal fungal infection. The nurse provides patient information for self- administration of a vaginal antifungal medication. What will the nurse include in the instructions? A)"Insert low into the opening of the vagina." B)"Discontinue use during menstruation." C)"Remain recumbent for at least 15 minutes after insertion." D)"Rub the cream into the vaginal wall after insertion."
Ans:C Feedback: The patient should remain recumbent at least 10 to 15 minutes after the medication is deposited high in the vagina so that leakage will not occur and absorption will take place. The effectiveness of the medication is determined by the consistent application for each specified dose for maximal results. The nurse would instruct the patient to continue the medication during menstruation. Stopping the drug and restarting it later can lead to the development of resistant strains of the drug. The cream need not be rubbed into the vaginal wall as it will coat the wall naturally after insertion.
What supplement would be safest for a diabetic female athlete wishing to improve athletic performance? A)Bee pollen B)Damiana C)Wild yam D)Spirulina
Ans:C Feedback: Wild yam is an estrogen-like herb used to increase athletic performance, slow the aging process, and improve energy and stamina. It can be toxic to the liver and may cause breast pain but is the safest of these supplements. Bee pollen is associated with serious allergic reactions and random studies have found wide variety of ingredients in each product. Damiana interferes with antidiabetic agents so it would not be appropriate for this patient. Spirulina may contain toxic metals and can cause serious reactions in children and pets. It interferes with vitamin B12absorption and there are no studies to prove it is effective in the claims it makes.
What is the priority reason for the nurse to consider questioning an order for tetracycline in a child younger than 8 years of age? A)Children younger than 8 years of age cannot take tetracyclines. B)Weight-bearing joints have been impaired in young animals given the drugs. C)Tetracyclines can damage developing teeth and bone in children younger than 8 years of age. D)Liver and kidney function may be damaged when it is given to children under 8 years of age.
Ans:C Feedback:Use tetracyclines with caution in children younger than 8 years of age because they can potentially damage developing bones and teeth. Although the drug does not cause damage to liver and kidneys, it may be contraindicated in patients with hepatic or renal dysfunction because it is concentrated in the bile and excreted in the urine. Fluoroquinolones, not tetracyclines, are generally contraindicated for use in children (i.e., those younger than 18 years of age) because weight-bearing joints have been impaired in young animals given the drugs. Clindamycin (Dalacin C) warrants monitoring hepatic and renal function when it is given to neonates and infants. Trimethoprim- sulfamethoxazole (Nu-Cotrimox) is used in children, although children younger than 2 months of age have not been evaluated. Children under 8 years of age can take tetracycline, but it should be used with caution.
The anatomy and physiology instructor is discussing reflex systems with the prenursing class. What system would the instructor say causes a muscle fiber contraction that relieves the stretch? A)Arch reflex systemB)Spinal reflex system C)Spindle gamma loop system D)Stretch receptor system
Ans:CFeedback: A spindle gamma loop system responds to stretch receptors or spindles on muscle fibers to cause a muscle fiber contraction that relieves the stretch. In this system, nerves from stretch receptors form a synapse with gamma nerves in the spinal cord, which send an impulse to the stretched muscle fibers to stimulate their contraction. These reflexes are responsible for maintaining muscle tone and keeping an upright position against the pull of gravity and are important in helping venous return when the contracting muscle fibers massage veins to help move the blood toward the heart. The arch reflex system and the stretch receptor system are distracters for this question. The spinal reflex system is not the reflex systems that respond to stretch receptors in the body.
A patient is diagnosed with an ascaris infection. The patient asks what the best way is to prevent ascaris infections. What is the nurse's best response? A)"Wash hands before eating."B)"Do not share hairbrushes or hats." C)"Wash fresh fruits and vegetables before eating." D)"Avoid heavily populated areas."
Ans:CFeedback: Ascaris infection occurs where sanitation is poor. Eggs in the soil are ingested with vegetables or other improperly washed foods containing the worm. The patients may be unaware until a worm in their stool is seen or the patient becomes quite ill. Teaching patients the importance of washing fresh fruit and vegetables will help them reduce risk of infection. Washing hands, avoiding sharing hairbrushes or hats, and being aware in populated areas will reduce the risk of other infections but do not relate to ascaris.
A patient is being discharged home from the hospital after receiving treatment for pneumonia. The patient is going home and continuing to take the same drugs he or she was taking before he or she was hospitalized. These drugs include an antianxiety medication and a medication for insomnia. The home care nurse is following this patient. On the initial visit what is the nurse's priority teaching point? A)The names and purposes of medications prescribed B)How to contact the provider if needed C)The importance of taking medications for insomnia only occasionally D)Warning signs that may indicate serious adverse effects
Ans:D Feedback: The home care nurse should provide thorough patient teaching, with a priority teaching point being the warning signs the patient may experience that indicate a serious adverse effect. Although this may have been discussed by the discharging nurse in the hospital, this is essential information for the patient to thoroughly understand. By the time the home care nurse visits, the patient should already have filled the prescriptions and know the names and purposes of the medications prescribed from the hospital nurse but it is a good idea to review this information, although it is not a priority. Medications for insomnia should be taken as prescribed. The patient should have received the provider's contact information when leaving the hospital but the home care nurse may need to review this, even though it is not the priority teaching point.
A student asks the pharmacology instructor if there is a way to increase the benefits and decrease the risks of antibiotic therapy. What would be an appropriate response by the instructor? A)Taking drugs not prescribed for the particular illness tends to maximize risks and minimize benefits. B)Never use antibiotics in combination with other prescriptions or in combination with other antibiotics. C)Maximize antibiotic drug therapy by administering the full dose when the patient has a fever. D)Use antibiotics cautiously and teach patients to complete the full course of an antibiotic prescription.
Ans:D Feedback: To prevent or contain the growing threat of drug-resistant strains of bacteria, it is very important to use antibiotics cautiously, to complete the full course of an antibiotic prescription, and to avoid saving antibiotics for self-medication in the future. A patient and family teaching program should address these issues, as well as the proper dosing procedure for the drug (even if the patient feels better) and the importance of keeping a record of any reactions to antibiotics. Thus, taking drugs not prescribed for the particular illness tends to maximize risks and minimize benefits. Also, if the infection is viral, antibacterial drugs are ineffective and should not be used.
A patient asks the nurse if he or she should use a topical antifungal. The nurse is aware that the most important contraindication to topical antifungals is what? A)Hepatic impairmentB)Renal impairmentC)Congestive heart failureD)Known allergy to any of the antifungal drugs
Ans:D Feedback: Topical antifungals are not absorbed systemically so they are not metabolized and excreted. As a result, the only contraindication would be an allergy to the drug. Hepatic and renal impairment and congestive heart failure would not be a contraindication because these drugs do not enter the bloodstream and impact these organ systems.
The nurse assesses the patient taking anabolic steroids for what serious adverse effects? A)Elevated blood urea nitrogen (BUN) B)Elevated blood glucose level C)BradycardiaD)Jaundice
Ans:D Feedback: Anabolic steroids all have black box warnings as alerts to the potentially serious effects of liver tumors, hepatitis, and blood lipid level changes that might be associated with increased risk of coronary artery disease. As a result, the nurse should assess for jaundice that could be an early indication of liver dysfunction. Elevated BUN, blood glucose levels, and bradycardia are not commonly reported adverse effects.
What criteria can the nurse use to describe all hormones? A)They are produced in very large amounts. B)They circulate until they are used by receptor cells. C)They are secreted directly into the tissue where they react. D)They travel in the blood to specific receptor sites.
Ans:D Feedback: Hormones are chemicals that are produced in the body and meet specific criteria. All hormones are produced in very small amounts and are secreted directly into the bloodstream. They travel in the blood to specific receptor sites throughout the body and are immediately broken down.
A patient in shock is receiving an infusion of dopamine when it is discovered that an extravasation has occurred. What drug should be on standby for this occurrence? A)Phenylephrine B)Propranolol C)Phenylalanine D)Phentolamine
Ans:D Feedback: Maintain phentolamine on standby in case extravasation occurs; infiltration of the site with 10 mL of saline containing 5 to 10 mg of phentolamine is usually effective in saving the area. Phenylephrine, propranolol, and phenylalanine are not indicated for use when extravasation occurs.
The nurse assesses a newly admitted patient and finds the muscle tone in his left leg has sustained muscle contraction. How will the nurse document this finding? A)Tonus B)Flaccid C)Atonic D)Spastic
Ans:D Feedback: Muscle spasticity is defined as a sustained muscle contraction. Soft and flabby muscle tone is defined as atonic. A limp muscle without tone is described as flaccid. The state of readiness, known as muscle tone (tonus), is produced by the maintenance of some of the muscle fibers in a contracted state.
How would the nurse describe selective toxicity? A)Selective toxicity interferes with a biochemical reaction common to many different organisms. B)Selective toxicity will decrease invading bacteria by interfering with the pathogens' ability to reproduce. C)Selective toxicity will eliminate bacteria by interrupting protein synthesis and damaging the pathogen's cell wall. D)Selective toxicity is the ability of the drug to kill foreign cells without causing harm to one's own body cells.
Ans:D Feedback: The choice of antibiotics in a clinical situation is determined by assessing which drug will affect the causative organism and lead to the fewest adverse effects. Selective toxicity is the ability of the drug to kill foreign cells without causing harm to the human body cells. How the antibiotic works to kill bacteria varies by drug type and may reduce the ability to reproduce, damage the cell wall, or interfere with a biochemical reaction, but this is a description of how the antibiotic works and does not describe selective toxicity
When taking the history of a patient, which information should alert the nurse to a possibility of trichinosis?
Ate undercooked pork
The most common adverse effects include the following: of adenosine
Atrial tachydysrhythmias AV block Cardiac arrest Ventricular dysrhythmias Atrial fibrillation Bronchospasm Adenosine frequently causes asystole for a few seconds. No treatment is required due to the short half-life of the drug.
Which drug can further decrease heart rate when taken with amiodarone?
Beta blockers Drug-drug interactions with beta blockers can further decrease heart rate when taken with amiodarone.
Before the nurse administers isosorbide mononitrate [Imdur], what is a priority nursing assessment?
Assess blood pressure. Isosorbide mononitrate [Imdur] is a vasodilator and thus can cause hypotension. It is important to assess blood pressure before administering.
A nurse is preparing to administer digoxin to a patient who is complaining of nausea. Which action is the nurse's priority?
Assess for bradycardia.
The nurse is assessing a patient who is taking verapamil for atrial fibrillation and notes 1+ edema to the ankles and feet. Which action would the nurse take?
Assess for heart failure
Which action should the nurse take when caring for a patient receiving triamterene [Direnium]?
Assess potassium levels Triamterene [Direnium] is a potassium-sparing diuretic. The nurse should monitor potassium for potential hyperkalemia. Urine output should be assessed more frequently than every other day. Hypoglycemia and hypernatremia are not common adverse effects of this drug.
Before administering digoxin, which action will the nurse take?
Assess the apical pulse.
The nurse is assessing a patient who is taking verapamil for atrial fibrillation and notes 1+ edema to the ankles and feet. Which action would the nurse take?
Assess the patient for heart failure
A patient is taking hydrochlorothiazide [Microzide]. On assessment, the nurse notes that the patient has muscle weakness, cramping, and leg discomfort. What should be the nurse's first intervention?
Assess the serum potassium level Hydrochlorothiazide [Microzide] can cause hypokalemia, characterized by muscle weakness, cramping, and leg discomfort. The nurse should immediately assess the patient's serum potassium level to determine the course of action. Giving calcium supplements does not reduce the symptoms caused by potassium deficiency. The patient is experiencing hypokalemia, not hypernatremia; reducing salt is for hypernatremia. Reducing the dose of the medication will not help restore the electrolyte balance.
Which self-assessment technique would the nurse include when teaching a patient about using methimazole for hyperthyroidism? Assessing pulse rate Counting respirations Inspecting skin for discolorations Keeping a dietary record
Assessing pulse rate
What is true regarding treatment of a hospitalized patient with pelvic inflammatory disease (PID)?
Because multiple organisms are likely to be involved in PID, drug therapy must provide broad coverage. No single drug can do this, so combination therapy is required. Because PID can be difficult to treat, and because the consequences of failure can be severe (eg, sterility), many experts recommend that all patients receive intravenous antibiotics in a hospital.
C (Antiarrhythmic drugs can cause both hypotension and bradycardia; therefore it is important to assess blood pressure and apical pulse before administration. Peripheral pulses are not as reliable as the apical pulse assessment.)
Before administering a dose of an antidysrhythmic drug to an assigned patient, which assessments would be of highest priority? Urine output and specific gravity Temperature and pulse rate Apical pulse and blood pressure Peripheral pulses and level of consciousness
Which teaching points would a nurse share with a patient newly prescribed the ethinyl estradiol plus norelgestromin patch (Ortho Evra®) who is switching from an oral combined hormonal contraception (CHC)?
Before applying, the patient should ensure the skin is dry and free from lotions, creams, or oils. Apply the patch on the first day of the menstrual cycle when bleeding occurs. No backup contraception is needed. If the patch comes off and has not been off for more than 24 hours, it should be reattached. Backup contraception is not needed. If the patch comes off and remains off for more than 24 hours, a new cycle should be started with backup contraception needed for 7 days.
Which outcome should a nurse include in the plan of care for a patient who is to start taking chloroquine [Aralen] prophylactically
Begin oral therapy 1 week before expected exposure
A 16-year-old girl comes to the clinic complaining of severe menstrual cramps. The girl is concerned about the pain and worried that "something is wrong." The nurse explains to the patient that she has cramping during her menstrual period because of what? A)An increase in the levels of estrogen and progesterone, which cause uterine contractions B)Low levels of plasminogen in the uterus that cause the shedding of the lining of the uterus C)Prostaglandins in the uterus, which stimulate uterine contractions to clamp off vessels as the lining of her uterus sheds D)An increase in progesterone and a decrease of estrogen cause the lining of the uterus to slough away
C Feedback: Prostaglandins in the uterus stimulate uterine contractions to clamp off vessels in the lining of the uterus, which is the cause of the cramping. The decrease of estrogen and progesterone after the involution of the corpus luteum triggers the release of follicle- stimulating hormone (FSH) and luteinizing hormone (LH). The decreased levels of FSH and LH cause the inner lining of the uterus to slough off because the vascular system is no longer being stimulated. High, not low, levels of plasminogen in the uterus prevent clotting of the lining as the vessels shear off.
A staff member asks how calcium channel blockers (CCBs) work. Which response should the nurse provide?
CCBs relax vascular smooth muscle. By blocking calcium channels, CCBs inhibit muscle contraction in the coronary arteries and peripheral arteries, resulting in relaxed vascular smooth muscle (vasodilation). CCBs have a negative inotropic effect by blocking calcium entry, which decreases the force of contractions. CCBs have no direct role in sodium activity. Vasodilation from CCBs decrease arterial pressure.
A patient with a history of alcoholism is being treated for a urinary tract infection. A prescription for which cephalosporins would cause the nurse to question the provider?
Cefazolin (used to treat cellulitis, urinary tract infections, pneumonia, endocarditis, and biliary tract infections) and cefotetan (used to treat bacterial infections in many different parts of the body and given before certain types of surgery to prevent infections) can cause a serious state of alcohol intolerance. If a patient taking either of these drugs ingests alcohol, a serious disulfiram-like reaction can occur. Since this can be dangerous, a patient using these cephalosporins must not consume alcohol in any form. Cefadroxil is used to treat strep throat, skin, and urinary tract infections and does not produce a potentially serious alcohol intolerance. Cefdinir is usually used to treat bronchitis, otitis media, sinus infections, pneumonia, cellulitis, and strep throat, and it does not cause a potentially serious alcohol intolerance. Ceftaroline is usually used to treat pneumonia rather than a urinary tract infection, and it does not cause a potentially serious alcohol intolerance.
Which is considered the most widely used group of antibiotics because of their bactericidal nature, resistance to beta-lactamases, and activity against a broad spectrum of pathogens?
Cephalosporins are considered the most widely used antibiotics because of their bactericidal nature, their resistance to beta-lactamases, and their activity against a broad spectrum of pathogens. Aminoglycosides and penicillins are bactericidal. Penicillins, aminoglycosides, and tetracyclines are considered narrow-spectrum antibiotics.
The nurse is caring for a patient with newly diagnosed hypertension who has been prescribed metoprolol. Which teaching would the nurse include?
Change positions slowly
The patient is admitted for the management of a hypertensive emergency. The healthcare provider prescribes sodium nitroprusside [Nipride] drug therapy. What is the priority nursing action during this treatment? A. Observe for respiratory depression. B. Monitor the electrocardiogram for tachycardia. C. Initiate oxygen therapy via nasal cannula at 2 L/min. D. Adjust the intravenous infusion rate to the blood pressure response.
D. Adjust the intravenous infusion rate to the blood pressure response. The nurse will adjust the rate of infusion based on the patient's blood pressure. Respiratory depression is not associated with administration of this drug. Oxygen therapy is not necessary and nitroprusside causes very little tachycardia.
The nurse is preparing to administer minoxidil [Loniten] 5 mg orally. What is the only cardiovascular indication for this medication? A. Heart failure B. Myocardial infarction C. Angina pectoris D. Severe hypertension
D. Severe hypertension Because of its serious adverse effects, minoxidil is reserved for patients who have failed to respond to safer drugs. The only cardiovascular indication for minoxidil is severe hypertension.
4 (Amiodarone has two very significant drug interactions, namely with digoxin and warfarin. Clients often refer to anticoagulants as "blood thinners." The nurse should verify which medication the client is taking, then notify the healthcare provider. When amiodarone is prescribed in clients taking warfarin, it is recommended to reduce the dose of warfarin by 50% at the start of warfarin therapy. Amiodarone adverse effects include visual halos, photophobia, and dry eyes; but wearing eyeglasses is not a contraindication. Amiodarone is an antidysrhythmic, and there should be no cross sensitivities with antibiotics. The client may get faint at the site of needles, however the priority of care is to eliminate dysrhythmias. The nurse can provide emotional reassurance and compassionately administer the amiodarone to help reduce the client's fears. )
The health care provider has prescribed amiodarone for a client with ventricular dysrhythmias. The nurse verifies the client's medical history and should notify the healthcare provider when the client states 1 "I wear eyeglasses to read print up close." 2 "I break out in a rash when I take antibiotics." 3 "I get faint when I see needles." 4 "I take a blood thinner so I don't get clots."
1 (All antidysrhythmics can be taken with food to relieve an upset stomach. Antacids should be taken 2 hours before or 2 hours after taking the antirhythmic drugs in order to avoid interfering with drug absorption. The client should be instructed to notify the prescriber if any type of rash or breathing problems develop. These may be signs of hypersensitivity or a systemic lupus erythematous-like syndrome that can develop in about 30% of clients taking procainamide long-term.)
The healthcare provider discontinues a client's quinidine and prescribes procainamide. The client asks the nurse about the possible side effects of this medication. What is the nurse's best response? 1 "Take this medication with food to relieve an upset stomach." 2 "Taking an antacid with this medication will relieve digestive problems." 3 "Benadryl can be taken with the medication if you develop a rash or breathhing problems." 4 "Use over the counter steroid cream if a red, swollen rash occurs."
The nurse reports which assessment finding as contributing to the cardioprotective effect in a patient receiving metoprolol?
The heart rate decreased from 130 to 98 beats/min. Metoprolol slows the conduction through the atrioventricular node, thereby decreasing the heart rate.
C (Patients taking amiodarone must have baseline and serial pulmonary function tests in order to monitor for potential pulmonary toxicity.)
The most severe adverse effects of amiodarone are evidenced in which body system? Renal Hepatic Pulmonary Hematologic
1, 2, 5 (Terbinafine [Lamisil] is highly active against dermatophytes and is used to eradicate fungal infection of the nails (onychomycosis) and as topical therapy for ringworm infections (tinea corporis, tinea pedis). It is not effective against oropharyngeal and vulvovaginal candidiasis.)
The nurse identifies terbinafine [Lamisil] as useful for treating which conditions? (Select all that apply.) 1 Onychomycosis 2 Tinea corporis 3 Oropharyngeal candidiasis 4 Vulvovaginal candidiasis 5 Tinea pedis
A The primary health care provider would prescribe nasal administration of glucocorticoids to manage rhinitis associated with polyps as well as to prevent the recurrence of polyps. Long-term glucocorticoid therapy is effective in managing and preventing the recurrence of polyps. A 1-week tapered course of oral corticosteroid may be prescribed along with glucocorticoid nasal spray. Antibiotics are prescribed to control any underlying infections before corticosteroid therapy is initiated, but they are less effective in preventing the recurrence of polyps after surgical removal. Deep-breathing exercises may cause temporary relief, and these are very challenging in such patients. Grape and citrus fruit juices help in tissue repair and healing. They will not cause the polyps to recur.
The nurse is caring for a patient who has undergone nasal surgery for the removal of polyps. Which treatment strategy will the nurse expect to be used to prevent the recurrence of polyps? A. To administer glucocorticoids to the patient B. To administer antibiotics to the patient C. To suggest deep-breathing exercises D. To avoid drinking grape and citrus fruit juices
1 (The most serious adverse effect of this drug is pulmonary toxicity, which involves a clinical syndrome of progressive dyspnea and cough accompanied by damage to the alveoli.)
The nurse is caring for patient who is being treated with amiodarone (Cordarone). The nurse notes that the patient is experiencing a hacking cough. The highest priority action on the part of the nurse is to 1 notify the physician regarding this symptom. 2 administer the cough syrup that has been ordered. 3 document the findings in the patient's chart. 4 administer medication to help the patient rest.
The nurse is administering pasiriotide to a patient with Cushing's disease secondary to a pituitary tumor. Which phrase describes the rationale for using this drug? To decrease inflammation before surgery To shrink the pituitary tumor To block production of adrenocorticotropic hormone (ACTH) To increase retention of sodium
To block production of ACTH
Which phrase describes the therapeutic goal in using octreotide to treat acromegaly? To control acromegaly symptoms To cure this health alteration To reverse the disease process To prepare the person for surgery
To control acromegaly symptoms
A patient who recently started taking warfarin asks the nurse why laboratory work needs to be obtained every 3 to 4 days. Which response would the nurse provide?
To ensure adequate dosing
The nurse is assessing a pregnant patient who has active herpes simplex virus type 2 (HSV-2). What precautions should the nurse suggest to the patient to ensure the newborn's safety? 1 To receive a vaccination 2 To take antiviral therapy in first trimester 3 To increase the intake of iron supplements 4 To give birth via cesarean section (C-section)
To give birth via cesarean section (C-section) - Patients infected with HSV-2 are usually recommended to give birth via C-section to prevent the baby from contracting the infection.
C (Grapefruit juice can also inhibit the metabolism of quinidine, which increases the risk of cinchonism, or quinism, which is a pathological condition caused by an overdose of quinidine or its natural source, cinchona bark. Quinine is medically used to treat malaria..)
To prevent the occurrence of cinchonism in a patient prescribed quinidine, what does the nurse emphasize as important? Wear sunscreen. Change positions slowly. Avoid drinking grapefruit juice. Increase dietary intake of potassium.
3 (Flucytosine [Ancobon] is used for serious infections caused by Candida and Cryptococcus neoformans. Bone marrow suppression may cause fatal agranulocytosis, so symptoms of bruising, fever, and fatigue could indicate life-threatening conditions. The other statements are true; however, they are not the priority concern. Flucytosine [Ancobon] is usually combined with amphotericin B. Treatment may require ingestion of 10 capsules 4 times per day. Taking these pills for a short time helps to reduce nausea. Hepatotoxicity is mild and reversible; liver function is monitored while the patient is receiving treatment)
When providing teaching for a patient starting flucytosine [Ancobon] therapy, the nurse identifies what as the priority concern? 1 "You will have weekly blood draws to monitor your liver function." 2 "Another very strong medication may be needed in addition to this one." 3 "You'll need to report any symptoms of bruising, fever, and fatigue." 4 "The dose is 10 pills, so take a few at a time over a 15-minute interval." .
3, 4
When teaching a patient about albendazole [Albenza] therapy, the nurse will include which statements? (Select all that apply.) 1 "Take the medication on an empty stomach." 2 "The drug is safe to use during pregnancy." 3 "Liver function tests should be done before and periodically during treatment." 4 "The drug is generally well tolerated." 5 "Use of the drug causes paralysis in the helminth."
Class IV Antidysrhythmic Drugs identify high risk patients
When used to manage dysrhythmias, verapamil and diltiazem should be given only after checking and documenting pulse rates and blood pressures. The nurse should withhold the drug if the heart rate is 60 beats/min or less, systolic blood pressure is 90 mm Hg or lower, or if tachydysrhythmia occurs; the nurse should then contact the health care provider for further instructions.
4
Which antifungal agent is used as a one-time oral dose to treat vaginal yeast infections? 1 Nystatin [Mycostatin] 2 Caspofungin [Cancidas] 3 Voriconazole [Vfend] 4 Fluconazole [Diflucan]
griseofulvin
Which antifungal, active only against dermatophytes, acts by depositing in newly formed keratin and disrupting microtubule structure?
B (Calcium channel blockers are effective in treating both hypertension and dysrhythmias secondary to their negative inotropic and chronotropic effects.)
Which class of drugs is used to treat both hypertension and dysrhythmias? Sodium channel blockers Calcium channel blockers Angiotensin-converting enzyme (ACE) inhibitors Direct-acting vasodilators
lindane
Which ectoparasiticide agent is not used first line for scabies or pediculosis, due to neurotoxicity/seizures, and requires a Medication Guide if dispensed?
2
Which factor in a patient's history is most likely related to the development of Pediculus humanus capitis? 1 Lower socioeconomic status 2 Sharing of hairbrushes and hats 3 Multiple sexual partners 4 Contact with infested pets
2, 3
Which factors increase a person's risk of acquiring a helminthic infestation? (Select all that apply.) 1 Loss of rectal sphincter tone 2 Poor water sanitation 3 Cost of treatment medication 4 Inadequate vitamins in the diet 5 Pre-existing hepatic disease
2
Which instruction should a nurse provide to the parent of a child with an enterobiasis (pinworm) infestation? 1 "Chills and fever are likely, so regular doses of an anti-inflammatory medication will help." 2 "All other members of the family need to be treated, because this is easily transmitted." 3 "Don't allow your child to go barefoot until the treatment regimen is completed." 4 "Make sure all meat, especially pork, is thoroughly cooked to prevent relapse."
A Glucocorticoids play a major role in carbohydrate, lipid, and protein metabolism within the body. They are produced in increasing amounts during stress. They cause an increase in serum sodium and serum glucose concentrations, thus precipitating hypernatremia and hyperglycemia as adverse effects, respectively. They are used as immunosuppressants. Hence they are not involved in stimulating defense mechanisms; rather, they suppress them.
Which statement about glucocorticoids is most relevant? A. They influence carbohydrate, fat, and protein metabolism. B. They are not produced during stressful situations. C. They decrease serum sodium and glucose concentrations. D. They stimulate defense mechanisms to produce immunity.
2, 3, 5
Which statement will the nurse include when teaching a patient about ivermectin [Stromectol] therapy? (Select all that apply.) 1 "Apply the drug directly to the ectoparasite infestation." 2 "A second dose of the drug usually is needed." 3 "Resistance to the drug is uncommon." 4 "Ivermectin is considered a first-choice drug for treating head lice." 5 "The most common adverse effects are headache and abdominal pain."
The electrical conduction system of the heart is also noticeably affected
by digoxin, as is cardiac automaticity. Digoxin reduces dysrhythmias by its effects on the SA and AV node (negative chronotropic and dromotropic effects). Digoxin also decreases conduction through the AV node by acting as a direct depressant on the AV node.
What hormone stimulates the release of the follicle-stimulating hormone (FSH) from both male and female glands? A)Growth hormone-releasing hormone (GHRH) B)Thyrotropin-releasing hormone (TRH) C)Gonadotropin-releasing hormone (GnRH) D)Prolactin-releasing hormone (PRH)
c The male and female glands respond to luteinizing hormone (LH) and FSH, which are released from the anterior pituitary in response to stimulation from GnRH that is released from the hypothalamus. GHRH stimulates the release of the growth hormone, which targets cell growth. TRH stimulates the thyroid-stimulating hormone, which targets the thyroid gland. PRH stimulates the release of prolactin, which is necessary for milk production.
IV verapamil and diltiazem are used in the setting of
cardiac dysrhythmias. Injections should be administered evenly (over 2 to 3 minutes). Patients must be monitored for changes in heart rate and for ECG changes, including AV block and prolonged PR or QT interval. The ability to perform cardioversion and cardiac pacing should be immediately available. Verapamil IV: Bolus: 0.075 to 0.15 mg/kg over 2 min; followed by second bolus of 0.15 mg/kg if needed. Maintenance: 0.005 mg/kg/min Diltiazem IV: Bolus: 0.25 mg/kg IV bolus over 2 min; followed by second bolus of 0.35 mg/kg over 2 min Maintenance: 10 mg/hr; increase by 5 mg/hr for max 15 mg/hr as needed
Minoxidil works by producing
direct vasodilation to arterial smooth muscle; it has little effect on veins.
For which side effects would the nurse monitor in a patient taking ezetimibe?
dizziness myalgia abdominal pain
Side effects of sodium nitroprusside include
dizziness, headache, nausea, vomiting, and irritation at injection site.
A nurse provides teaching about which antibiotic to a patient requiring prophylaxis for chloroquine-resistant malaria
doxycycline
Adenosine is used as the
drug of choice for PSVT. Adenosine is not effective in ventricular dysrhythmias, atrial fibrillation, or atrial flutter.
