Nursing Elites

1. The practical nurse is assigned a client on digoxin therapy. Which finding is likely to predispose this client to developing digoxin toxicity?

• A. Hyponatremia
• B. Hypernatremia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: D

Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation. Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.

2. A client receiving enalapril reports a persistent dry cough. The nurse should explain that this side effect is related to which medication action?

• A. It reduces the production of angiotensin II.
• B. It increases the production of angiotensin II.
• C. It causes increased production of bradykinin.
• D. It increases the production of aldosterone.

Correct answer: C

Rationale: The correct answer is C. Enalapril, an ACE inhibitor, inhibits the conversion of angiotensin I to angiotensin II, leading to increased levels of bradykinin. The accumulation of bradykinin is responsible for the persistent dry cough associated with ACE inhibitors like enalapril. Choices A, B, and D are incorrect because enalapril does not directly affect the production of angiotensin II or aldosterone. Instead, it primarily impacts the renin-angiotensin-aldosterone system by inhibiting the conversion of angiotensin I to angiotensin II, leading to bradykinin accumulation.

3. A client is receiving heparin to treat a deep vein thrombosis. The nurse should monitor which laboratory result to assist in evaluating the efficacy of the drug?

• A. Platelet count
• B. Prothrombin time
• C. Partial thromboplastin time
• D. Serum levels of protamine sulfate

Correct answer: C

Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.

4. A client with diabetes mellitus type 2 is prescribed saxagliptin. The nurse should include which instruction in the client's teaching plan?

• A. Report any signs of pancreatitis to the healthcare provider.
• B. Take this medication with meals.
• C. Avoid alcohol while taking this medication.
• D. Report any signs of heart failure to the healthcare provider.

Correct answer: A

Rationale: Corrected Rationale: When a client with diabetes mellitus type 2 is prescribed saxagliptin, it is crucial to instruct them to report any signs of pancreatitis to the healthcare provider. Saxagliptin can lead to pancreatitis as a side effect, making it essential for clients to be vigilant about recognizing and reporting any related symptoms promptly for timely intervention and management. Choice B is incorrect because saxagliptin can be taken with or without meals. Choice C is not specifically associated with saxagliptin use. Choice D is incorrect as heart failure is not a common side effect of saxagliptin.

5. A client with hypertension is prescribed atenolol. The nurse should monitor for which potential side effect?

• A. Bradycardia
• B. Tachycardia
• C. Dry mouth
• D. Hypotension

Correct answer: A

Rationale: When a client is prescribed atenolol, a beta-blocker, the nurse should monitor for bradycardia, which is a potential side effect. Atenolol works by slowing the heart rate, so monitoring the client's heart rate is essential to detect and manage bradycardia promptly.
