A nurse is caring for a client who has difficulty swallowing medications and is prescribed enteric-coated aspirin PO once daily. The client asks if the medication can be crushed to make it easier to swallow. Which of the following responses should the nurse provide?

"Crushing the medication might cause you to have a stomachache or indigestion." Rationale: The pill is enteric-coated to prevent breakdown in the stomach and decrease the possibility of GI distress. Crushing the pill destroys that protection.

A nurse is caring for a client who has thrombophlebitis and is receiving heparin by continuous IV infusion. The client asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give?

"Heparin does not dissolve clots. It stops new clots from forming."

A nurse is caring for a client who has heart failure and a prescription for digoxin. Which of the following statements by the client indicates an adverse effect of the medication?

"I feel nauseated and have no appetite." Answer Rationale: Anorexia, nausea, vomiting, and abdominal discomfort are early signs of digoxin toxicity.

A nurse is teaching a client who takes warfarin daily. Which of the following statements by the client indicates a need for further teaching?

"I have started taking ginger root to treat my joint stiffness." Rationale: Ginger root can interfere with the blood clotting effect of warfarin and place the client at risk for bleeding. This statement indicates the client needs further teaching.

A nurse is caring for a client who has deep vein thrombosis and has been on heparin continuous infusion for 5 days. The provider prescribes warfarin PO without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following statements should the nurse make?

"Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level." Rationale: Heparin and warfarin are both anticoagulants that decrease the clotting ability of the blood and help prevent thrombosis formation in the blood vessels. However, these medications work in different ways to achieve therapeutic coagulation and must be given together until therapeutic levels of anticoagulation can be achieved by warfarin alone, which is usually within 1 to 5 days. When the client's PT and INR are within therapeutic range, the heparin can be discontinued.

A nurse is caring for a client who has congestive heart failure and is taking digoxin daily. The client refused breakfast and is complaining of nausea and weakness. Which of the following actions should the nurse take first?

A. Check the client's vital signs. Rationale: It is possible that the client's nausea is secondary to digoxin toxicity. By obtaining vital signs, the nurse can assess for bradycardia, which is a symptom of digoxin toxicity. The nurse should withhold the medication and call the provider if the client's heart rate is less than 60 bpm.

A nurse is providing teaching to a client who has renal failure and an elevated phosphorous level. The provider instructed the client to take aluminum hydroxide 300 mg PO three times daily. For which of the following adverse effects should the nurse inform the client?

A. Constipation Rationale: Constipation is a common side effect of aluminum-based antacids. The nurse should instruct the client to increase fiber intake and that stool softeners or laxatives may be needed.

A nurse is caring for a client who is taking lisinopril. Which of the following outcomes indicates a therapeutic effect of the medication?

A. Decreased blood pressure Rationale: Lisinopril, an ACE inhibitor, may be used alone or in combination with other antihypertensives in the management of hypertension and congestive heart failure. A therapeutic effect of the medication is a decrease in blood pressure.

A nurse is providing teaching to a client who has hypertension and a new prescription for captopril. Which of the following instructions should the nurse provide?

A. Do not use salt substitutes while taking this medication. Rationale: Captopril, an ACE inhibitor, can cause hyperkalemia due to potassium retention by the kidney. The client should avoid salt substitutes, as most of them are high in potassium.

A nurse is obtaining a medical history from a client who is to start warfarin therapy and currently uses herbal supplements at home. The nurse should inform the client that which of the following herbal supplements can interact adversely with warfarin?

A. Feverfew Rationale: The nurse should instruct the client to avoid taking feverfew while taking warfarin because it will increase the anticoagulant effect.

A nurse in a coronary care unit is admitting a client who has had CPR following a cardiac arrest. The client is receiving lidocaine IV at 2 mg/min. When the client asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?

A. Prevents dysrhythmias Rationale: Lidocaine is an antidysrhythmic medication that delays the conduction in the heart and reduces the automaticity of heart tissue.

A nurse is monitoring a client who received epinephrine for angioedema after a first dose of losartan. Which of the following data indicates a therapeutic response to the epinephrine?

A. Respirations are unlabored. Rationale: Losartan is an angiotensin receptor blocker (ARB). Both ARBs and angiotensin converting enzyme (ACE) inhibitors have the adverse effect of angioedema. The primary symptom of angioedema is swelling of the tongue, glottis, and pharynx. This results in limitation or blockage of the airway. Angioedema causes the capillaries to become more permeable, resulting in fluid shifting into the subcutaneous tissues. Although the mouth and throat are most often affected, any area may be involved in the process. Untreated, angioedema can result in death. Improvement of respiratory effort following the administration of epinephrine is the most important therapeutic indicator.

A nurse is teaching a client about taking diphenhydramine. The nurse should explain to the client that which of the following is an adverse effect of this medication?

A. Sedation

A nurse is preparing to transfuse one unit of packed RBC to a client who experienced a mild allergic reaction during a previous transfusion. The nurse should administer diphenhydramine prior to the transfusion for which of the following allergic responses?

A. Urticaria Rationale: For clients who have previously had allergic reactions to blood transfusions, administering an antihistamine such as diphenhydramine prior to the transfusion might prevent future reactions. Allergic reactions typically include urticaria (hives). B. Fever

A nurse is caring for a client who has cirrhosis and a prothrombin time of 30 seconds. Which of the following medications should the nurse plan to administer?

A. Vitamin K Rationale: A prothrombin time of 30 seconds indicates the clotting time is prolonged and bleeding could occur. Vitamin K injection increases the synthesis of prothrombin by the liver; therefore, the nurse should plan to administer vitamin k.

Agent(s) may be effective in terminating paroxysmal supraventricular tachycardia (PSVT)?

A. adenosine (Adenocard)

A nurse is teaching a client who has been taking prednisone to treat asthma and has a new prescription to discontinue the medication. The nurse should explain to the client to reduce the dose gradually to prevent which of the following adverse effects?

Adrenocortical insufficiency Rationale: Prednisone, a corticosteroid, is similar to cortisol, the glucocorticoid hormone produced by the adrenal glands. It relieves inflammation and is used to treat certain forms of arthritis, severe allergies, autoimmune disorders, and asthma. Administration of glucocorticoids can suppress production of glucocorticoids, and an abrupt withdrawal of the drug can lead to a syndrome of adrenal insufficiency.

Anorexia Answer Rationale: Anorexia, vomiting, confusion, headache, and vision changes are manifestations of digoxin toxicity.

A nurse is caring for a client who has poison ivy and is prescribed diphenhydramine. Which of the following instructions should the nurse give regarding the adverse effect of dry mouth associated with diphenhydramine?

B. "Chew on sugarless gum or suck on hard, sour candies." Rationale: Clients who report dry mouth can get the most effective relief by sucking on hard candies (especially the sour varieties that stimulate salivation), chewing gum, or rinsing the mouth frequently. It is the local effect of these actions that provides comfort to the client.

A nurse is providing discharge teaching for a client who has pulmonary edema and is about to start taking furosemide. Which of the following instructions should the nurse include?

B. Eat foods that contain plenty of potassium. Rationale: Furosemide, a high-ceiling (loop) diuretic, can cause potassium loss. The client should add potassium-rich foods to his diet, such as nuts, dried fruits, bananas, and citrus fruits.

A nurse is receiving a client who is immediately postoperative following hip arthroplasty. Which of the following medications should the nurse plan to administer for DVT prophylaxis?

B. Enoxaparin subcutaneous Rationale: Enoxaparin is a low molecular heparin that inhibits thrombus and clot formation. Preventive doses of enoxaparin are low and the client does not require monitoring of prothrombin time or activated partial thromboplastin time, making it the preferred treatment for DVT prophylaxis following orthopedic surgery.

A nurse is caring for a client who has heart failure and is receiving IV furosemide. The nurse should monitor the client for which of the following electrolyte imbalances?

B. Hyperuricemia Rationale: The nurse should monitor the client who is receiving IV furosemide for hyperuricemia. The nurse should instruct the client to notify the provider for any tenderness or swelling of the joints.

A nurse is preparing to administer verapamil by IV bolus to a client who is having cardiac dysrhythmias. For which of the following adverse effects should the nurse monitor when giving this medication?

B. Hypotension Rationale: Verapamil, a calcium channel blocker, can be used to control supraventricular tachyarrhythmias. It also decreases blood pressure and acts as a coronary vasodilator and antianginal agent. A major adverse effect of verapamil is hypotension; therefore, blood pressure and pulse must be monitored before and during parenteral administration.

B. Prothrombin time (PT)

A nurse is caring for a client who is prescribed warfarin therapy for an artificial heart valve. Which of the following laboratory values should the nurse monitor for a therapeutic effect of warfarin?

B. Prothrombin time (PT) Rationale: This test is used to monitor warfarin therapy. For a client receiving full anticoagulant therapy, the PT should typically be approximately two to three times the normal value, depending on the indication for therapeutic anticoagulation.

A nurse is reviewing the health history for a client who has angina pectoris and a prescription for propranolol hydrochloride PO 40 mg twice daily. Which of the following findings in the history should the nurse report to the provider?

B. The client has a history of bronchial asthma. Rationale: Beta-adrenergic blockers can cause bronchospasm in clients who have bronchial asthma; therefore, this is a contraindication to its use and should be reported to the provider.

A nurse is caring for a client who has a prescription for potassium chloride (KCL) 20 mEq PO daily. The nurse reviews the client's most recent laboratory results and finds the client's potassium level is 5.2 mEq/L. Which of the following actions should the nurse take?

C. Call the prescribing physician and inform her of the client's serum potassium level results. Rationale: As a potassium level of 5.2 mEq/L is above the expected reference range, the nurse should hold the medication and notify the provider of the client's serum potassium level.

A nurse is caring for a client whose serum potassium level is 5.3 mEq/L. Which of the following scheduled medications should the nurse plan to administer?

C. Furosemide Rationale: Furosemide results in loss of potassium from the nephron as part of its diuretic effect. This medication can be given when a client has an elevated potassium level and can lower the potassium level. For this client, the depletion of potassium is a beneficial effect. For a client who has a therapeutic potassium level, there would be a risk for hypokalemia due to the excretion of potassium.

A nurse is caring for a client who has thrombophlebitis and is receiving heparin by continuous IV infusion. The client asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give? a. It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level. b. A pharmacist is the person to answer that question. c.
