Correct Answer: B

Rationale: Amlodipine is a calcium channel blocker known to cause peripheral edema as an adverse effect. The nurse should monitor the client for swelling, particularly in the lower extremities, as it can indicate the development of this side effect.

Correct Answer: C

Rationale: Flumazenil is a competitive benzodiazepine antagonist that can reverse the sedative effects of benzodiazepines like Diazepam. In cases of oversedation, administering Flumazenil can help counteract the excessive sedation and other effects of Diazepam, thereby promoting the client's recovery and preventing potential complications.

Correct Answer: B

Rationale: The correct answer is B: 'Expect this medication to smell like rotten eggs.' Acetylcysteine contains sulfur, which gives it a characteristic rotten-egg odor. This odor is normal and expected when using this medication. Choices A, C, and D are incorrect because Acetylcysteine is not used to suppress cough, cause euphoria, or change urine color.

Correct Answer: B

Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin.

Correct Answer: B

Rationale: Spironolactone is a potassium-sparing diuretic, meaning it can cause potassium retention, leading to elevated potassium levels. A potassium level of 5.2 mEq/L is above the normal range (3.5-5.0 mEq/L) and indicates hyperkalemia, which can be a serious condition. Therefore, this finding should be promptly reported to the healthcare provider for further evaluation and management to prevent potential complications.
