Answers and Rationales
  1. Answer: D. An 80-year-old client with CHF. Extremely old clients are at greater risk for digitalis toxicity. Remember when it comes to adversity, the very old and very young are always at highest risk.
  2. Answer: C. Heart rate below 60. The apical heart rate must be monitored during therapy with digoxin, and the drug held for pulse below 60 and above 120. Remember that digoxin lowers the heart rate; therefore, the choice that reflects a low heart rate is the best selection.
  3. Answer: C. Increases the force of contraction. Inotropic drugs increase the force of contraction. Preload, not afterload, is decreased. Chronotropic drugs increase heart rate. Treatment of CHF is an indication for use not an action of inotropic drug.
  4. Answer: A. Monitor potassium level. Monitoring potassium is especially important because hypokalemia potentiates digoxin toxicity. B and C are incorrect because these data reflect overall CV status but are not specific for digoxin. Choice D are drugs usually administered with digoxin.
  5. Answer: D. 0.5-2.0 ng/mg. This is the correct therapeutic range for digoxin. Every nurse should know this information.
  6. Answer: B. Digoxin toxicity. Halos is a hallmark sign of digoxin toxicity. A, C and D are incorrect because subtherapeutic digoxin levels have no such effects.
  7. Answer: A. Increasing stroke volume and heart rate. The action of amrinone (Inocor) is to increase stroke volume, ejection fraction, and heart rate. Lanoxin, not amrinone, slows ventricular rate and increases cardiac output. The vasodilator effect of amrinone decreases peripheral vascular resistance. Any increase in cardiac output will enhance renal perfusion; this is not just specific to amrinone.
  8. Answer: D. Review medication regimen to identify if client is on IV furosemide (Lasix). Milrinone (Primacor) is incompatible with IV furosemide (Lasix), and many clients with CHF are taking furosemide. Assessing potassium, not sodium, is essential. Choice B is not done before administration but during administration. Assessment of CV status is not specific for milrinone and is indicated for any drug that affects the circulatory system.
  9. Answer: D. lidocaine (Xylocaine). Lidocaine is the only choice used to treat ventricular ectopy. A and C are class IA antiarrhythmics. Digoxin is a cardiac glycoside.
  10. Answer: B. SA node. Class IA antiarrhythmics have little effect on the SA node.
  11. Answer: D. procainamide (Pronestyl). Pronestyl is known for this serious side effect. Associate Pronestyl with plasma — P and P. This drug is known for its hematologic side effects.
  12. Answer: D. Frequent ventricular ectopy. Ventricular ectopy can be a life-threatening arrhythmia; therefore, the client needs an arrhythmic. Other choices are not arrhythmias that need to be treated.
  13. Answer: A. ECG. The ECG is the most important parameter to assess. B, C, and D need to be monitored, but the ECG is the most important.
  14. Answer: C. Drug levels. Knowing drug levels (peak and trough) is the only way to ensure there is enough drug in the body to work. Other choices do not demonstrate drug effect.
  15. Answer: A. bretylium (Bretylol). Among the choices, this is the only agent that must be monitored this closely. B, C, and D are given to outpatients as oral preparations.
  16. Answer: C. amiodarone (Cordarone). This is the most toxic drug and should be used only if other less toxic agents have been tried. Digoxin, on the other hand, is cardiotonic, not antiarrhythmic agent. B and D are not known for their toxicity.
  17. Answer: B. Bronchodilation and increased heart rate, contractility, and conduction. Bronchodilation results from stimulated beta receptors, and cardiac effects result from the stimulation of ß1 receptors. Choice A does not address respiratory effects of medication. Choice C is incorrect because α-stimulating drugs cause vasoconstriction. Bronchodilation, not bronchoconstriction, results from ß2 activity.
  18. Answer: B. color and temperature of toes and fingers. Because decreased perfusion is a side effect of norepinephrine (Levophed), the nurse must check circulation frequently. Capillary refill is not a reliable indication of perfusion in a shock state. Choices A and D are not specific for norepinephrine.
  19. Answer: A. Hypovolemic shock. Norepinephrine (Levophed) is contraindicated in hypovolemia. Neurogenic shock is an indication for norepinephrine use. Norepinephrine is given to maintain a systolic blood pressure of 80-100 mmHG. Decreased renal perfusion is an adverse reaction.
  20. Answer: C. the drug cannot be directly mixed in solutions containing bicarbonate or aminophylline. The nurse is responsible for knowing compatible solutions before administering dopamine (Intropin). It is important to know that drug action varies by dose, but the physician is responsible for determining the dose. Dopamine should not be used instead of fluid replacement. Choice D is incorrect because, although it is true, it is not the nurse’s primary concern. It is a collaborative action in which the physician is involved in determining the rate.
  21. Answer: C. arrhythmias. Dobutamine (Dobutrex) is not used to treat arrhythmias. Choices A, B, and D are conditions are conditions that respond to dobutamine.
  22. Answer: A. verapamil. Verapamil (Calan) has the strongest chronotropic effect and will cause a delay in conduction at the SA and AV nodes.
  23. Answer: B. nifedipine. Nifedipine has the strongest peripheral smooth muscle dilator effect of all the calcium channel blockers. Other choices have less of a vasodilator effect.
  24. Answer: D. Hypotension. Hypotension is more likely to occur in the elderly. Choices A, B, and C may occur but are not necessarily increased in frequency in elderly clients.
  25. Answer: B. nimodipine. Nimodipine is given in the neurologic client to prevent cerebral vasospasm. Choices A, C, and D are given in cardiac disease and in the management of hypertension only.
  26. Answer: B. Decreased peripheral vascular resistance. One of the effects of calcium channel blockers is to decrease peripheral vascular resistance. A, C, and D describe the opposite effects of calcium channel blockers.
  27. Answer: A. Pulmonary function tests. Unless the client has a history of pulmonary disease and pulmonary function tests are indicated, there is no need to include this in the routine assessment of the client taking ß blockers.
  28. Answer: B. Glucose. ß blockers influence glucose metabolism. Although A, C, and D are nice to have, there is no indication that routine assessment of thyrotropin, sodium, or creatine phosphokinase is needed.
  29. Answer: A. Catecholamines. Catecholamine receptor sites are blocked by the action of ß-blocking agents. Adrenergic sites may be blocked, but the more appropriate response is catecholamine receptors. Acetylcholine is not affected by ß blockers. Norepinephrine is a catecholamine.
  30. Answer: A. Bronchoconstriction. ß blockers should be avoided in bronchoconstrictive disease. B, C, and D are indications for the use of ß blockers.
  31. Answer: C. Smooth muscle relaxation. Nitrates cause smooth muscle relaxation, vasodilation, reduction of preload, and improved blood flow to the myocardium. Other choices have opposite effect of nitrates.
  32. Answer: A. Decreased myocardial oxygen demand. Nitrate administration will result in reduced preload and a decrease in myocardial oxygen demand and left ventricular end-diastolic volume.
  33. Answer: C. isosorbide PO. Isosorbide is one of the most frequently administered long-acting nitrates. PO nitrates are longer acting than IV or SL agents.
  34. Answer: C. Reduced mortality. Research has shown that when nitrates are administered early to the acute MI client, the effect is reduced mortality, infarct size, infarct extension, and related complications. Hypotension will result from nitrate administration, but it is not the reason for prescribing the drug. Tachycardia rather than bradycardia is more likely to occur with nitrate administration. The morbidity is already present because the client has the pain.
  35. Answer: A. Change position slowly. Clients taking nitrates should change position slowly to avoid orthostatic hypotension. It is not necessary to take the pulse before taking this drug. It is also not necessary to change the diet while taking this drug. It is contraindicated to chew sustained-release tablets.
  36. Answer: C. Promote sodium and water retention. Angiotensin is a potent vasoconstrictor that stimulate the release of aldosterone. Aldosterone release promotes sodium and water retention. The conversion of angiotensin I to II is not inhibited. Aldosterone promotes sodium retention not depletion. Vasoconstriction not vasodilation results.
  37. Answer: D. Hypotension. ACE inhibitors prevent vasoconstriction and lower blood pressure, placing the client at greater risk for postural (orthostatic) hypotension. ACE inhibitors reduce potassium excretion placing the client at risk for hyperkalemia. ACE inhibitors do not affect heart rate. ACE inhibitor promote sodium excretion thereby decreasing edema.
  38. Answer: B. “I need to increase my intake of orange juice, bananas, and green vegetables.”. The client needs to understand the risk of hyperkalemia and foods to eat in moderation. Taking medications with food will decrease therapeutic effects of ACE inhibitors. Excessive amounts of caffeine should be avoided. Avoidance of salt substitutes that are high in potassium decrease the risk of hyperkalemia.
  39. Answer: D. “This drug is used when other drugs have failed.” This response provides accurate information about the medication. Choice A placates the client and provides no information about the new medication. Choice B is defensive. Although choice C is true, there is no information provided to motivate the client.
  40. Answer: D. Increased sodium excretion and potassium reabsorption. The inhibition of aldosterone increases sodium excretion and reduces potassium excretion. ACE inhibitors increases renal blood flow. Excretion of sodium and water is enhanced by ACE inhibitors. Peripheral vascular resistance is decreased by vasodilation effect of ACE inhibitors.
  41. Answer: A. Relax smooth muscles. Vasodilators relax smooth muscle. They are used to treat hypertension, not hypotension. Stimulating the adrenergic receptors of peripheral sympathetic nerves causes blood vessels to contract. Choice D is not an action of vasodilators.
  42. Answer: B. Hypertension. Vasodilators are used to treat hypertension. They are not used to treat diabetes. Atrial fibrillation is not treated with vasodilators. Vasodilators are not used to treat hypotension.
  43. Answer: D. All of the above. All are vasodilators used primarily to treat peripheral or cerebral vascular obstructive disease.
  44. Answer: D. nitroprusside (Nitropress). Nitroprusside (Nitropress) is used in this situation. A and B are sympathomimetics used to treat hypotension. Papaverine is contraindicated in myocardial depressant states.
  45. Answer: D. All of the above. An important component in the treatment of peripheral vascular disease is health education on preventing further injury to ischemic tissues. Medication therapy is only one aspect.
  46. Answer: B. Inhibit the exchange of sodium for potassium. Aldosterone antagonists compete with endogenous aldosterone and prevent sodium reabsorption in exchange for potassium elimination. Aldosterone antagonists work on inhibiting the action of aldosterone rather than creating an osmotic gradient. Aldosterone antagonist do not cause metabolic acidosis. Aldosterone antagonists must work in the presence of endogenous aldosterone.
  47. Answer: D. Hearing loss. Patients receiving large doses of loop diuretics are at risk for developing ototoxicity.
  48. Answer: A. Fluid volume excess. Mannitol’s osmotic effect extends to the bloodstream, where increased osmotic pressure draws fluid into the vascular space, thus elevating intravascular volume.
  49. Answer: D. Are weak diuretics. Potassium-sparing diuretics are not potent diuretics when used alone. They are used as adjunctive therapy with other diuretics to minimize potassium loss. Potassium-sparing diuretics given during blood transfusions tend to cause hyperkalemia because potassium is present in the transfusion. These drugs block aldosterone’s effects. These drugs cause hyperkalemia, not hypokalemia.
  50. Answer: D. A 75-year-old man. Elderly clients are more sensitive to the effects of diuretics.
  51. Answer: D. Increase HDL. The desired effect of lipid-lowering agents is to decrease cardiac risk by lowering TC, TG, and LDL and increasing or maintaining HDL.
  52. Answer: B. LDL. An elevated LDL is the most significant risk factor for the development of atherosclerosis; therefore, for drug therapy to be effective, LDL must be reduced.
  53. Answer: C. Liver disease. All lipid-lowering agents except the bile acid sequestrants are potentially hepatotoxic, so the most significant contraindication is liver disease.
  54. Answer: D. Vitamin K. Vitamin K absorption may be reduced when giving these drugs. The only fat-soluble vitamin here is vitamin K, which is synthesized in the liver.
  55. Answer: A. lovastatin (Mevacor). Mevacor is known to cause constipation.
  56. Answer: A. Conversion of prothrombin to thrombin. Parenteral anticoagulants such as heparin work by disrupting conversion of prothrombin to thrombin. Tissue thromboplastin is formed in the extrinsic pathway as tissue is damaged. Oral anticoagulants work by interfering with vitamin K-dependent clotting factors. Prothrombin does not convert to fibrin.
  57. Answer: B. Abdominal fat. Heparin should be given in the abdominal area around the umbilicus, deep into the fat.
  58. Answer: B. 1 to 1.5 hours. The half-life of heparin is 60 to 90 minutes. This is important to know when bleeding occurs during heparin administration.
  59. Answer: D. protamine sulfate (Protamine). Protamine is the drug used to reverse the adverse effects of bleeding that occurs with heparin administration.
  60. Answer: C. 8 to 12. Initial extension of PT occurs within 8 to 12 hours after warfarin therapy begins.
  61. Answer: B. “I will take Ecotrin (Enteric coated aspirin) for my headaches”. Ecotrin is an aspirin-containing product and should be avoided due to the risk of bleeding.
  62. Answer: B. Activated partial thromboplastin time (aPTT). Activated partial thromboplastin time assess the therapeutic level of heparin.
    • Option A: Assess the therapeutic level of warfarin sodium (Coumadin).
    • Options C and D: Measures the aspect of the red blood cells.
  63. Answer: B. Activated partial thromboplastin time of 60 seconds. The normal range for activated partial thromboplastin time is 20-36 seconds. The activated partial thromboplastin time must be 1.5 to 2.5 times the normal value, the client’s Appt would be considered therapeutic if it was 60 seconds.
  64. Answer: D. Protamine sulfate. Protamine sulfate is the antidote that reverses the anticoagulant effects of heparin by binding to it.
    • Option A is the antidote for acetaminophen toxicity.
    • Option B is the antidote for magnesium sulfate toxicity.
    • Option C is the antidote for warfarin sodium toxicity.
  65. Answer: A. Stop the infusion and call the physician. Severe allergic reaction to streptokinase requires immediate discontinuation of Streptokinase,then notify the physician and administer an adrenergic, antihistamine, and/or corticosteroid agents as ordered.
  66. Answer: D. A blood pressure of 185/100 mm Hg. Thrombolytic therapy is contraindicated with uncontrolled hypertension (systolic BP >180 mm Hg and/or diastolic BP >110 mm Hg) because of the risk of cerebral hemorrhage.
    • Options A, B, and C may be present during the therapy but will not warrant the immediate knowledge of the physician before starting the therapy.
  67. Answer: C. Aminocaproic acid (Amicar). Bleeding can be reversed with the use of aminocaproic acid as an antidote for streptokinase.
    • Option A is the antidote for warfarin sodium toxicity.
    • Option B is the antidote for iron toxicity.
    • Option D is an antihistamine that can be used for any allergic reaction.
  68. Answer: B. Antiplatelet medications cannot be used with anticoagulants. Antiplatelet and anticoagulant therapies are effective in keeping a clot from forming or stopping the growth of one.
  69. Answer: A. Check the blood pressure and heart rate. The client is experiencing signs of procainamide toxicity, the priority nursing action is to obtain vital signs immediately.
    • Options B and C are done after checking the vital signs.
    • Option D will cause hypotension.
  70. Answer: D. Observe for signs of bleeding. Bleeding is the priority concern for a client taking thrombolytic medication.
    • Options A and B are monitored but are not the primary concern.
    • Option C is not related to the use of medication.
  71. Answer: B. 0.5-2 ng/ml. The therapeutic level of digoxin is 0.5-2 ng/ml.
  72. Answer: D. Complaints of dyspnea. Complaints of dyspnea is a sign of bronchospasm which is one of the serious complication of beta blockers.
    • Options A and B shows a decrease in the blood pressure and heart rate which are expected in this therapy.
    • Option C is a side effect of this medication.
  73. Answer: C. “This medication may mask some of the symptoms of hypoglycemia such as tremor, palpitation, and rapid heartbeat. Beta-blockers such as metoprolol may increase the risk of hypoglycemia in patients receiving insulin. In addition, beta-blockers may mask some of the symptoms of hypoglycemia such as tremor, palpitation, and rapid heartbeat, making it more difficult to recognize an oncoming episode.
  74. Answer: D. Hypokalemia and hyperglycemia. Metolazone is a thiazide diuretic that may put clients risk for hypokalemia, hyperglycemia, hyperlipidemia, hypercalcemia and hyperuricemia.
  75. Answer: C. Blood pressure. The priority assessment in this situation will be the monitoring of the blood pressure because hypotension poses a risk in this medication.
    • Options A, B, and D are monitored but they are not the priority.
  76. Answer: C. “I will continue taking nicotinic acid as part of the treatment”. A combination of Cholestyramine (Questran) and nicotinic acid damages the liver.
    • Options A, B, and D are true regarding this medication.
  77. Answer: A. “I should take aspirin 30 minutes before nicotinic acid”. The use of aspirin or a nonsteroidal anti-inflammatory drug 30 minutes before decreases flushing which is a side effect of taking nicotinic acid.
    • Option B: Drinking alcohol will cause liver abnormalities.
    • Option C is a sign of liver dysfunction and should be immediately informed the physician.
    • Option D: This medication is taken with meals to decrease gastrointestinal upset.
  78. Answer: D. Tremors. Signs of digoxin toxicity are as follows, anorexia, nausea, vomiting, diarrhea, and blurred vision.
  79. Answer: B. Sulfa allergy. Loop diuretics such as bumetanide are sulfa-based medications, and a client with sulfa allergy is at risk for an allergic reaction.
  80. Answer: C. The client still complains of chest pain with a pain scale of 2/10. The goal for the client with an acute myocardial infarction is to eliminate the pain. Even pain related at a level of 2/10 should be managed with an additional dose of morphine.
    • Options A, B, and D: although hypotension, respiratory depression, and tachycardia are the side effects of morphine but they do not require further action at this time.
