Correct Answer: B

Rationale: When a client starts taking amitriptyline, an important adverse effect to monitor for is urinary retention. Amitriptyline is a tricyclic antidepressant that can cause anticholinergic effects, including urinary retention. It is crucial to educate the client on recognizing and reporting this adverse effect to their healthcare provider.

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: A

Rationale: Bevacizumab is known to potentially cause hypertension as a common adverse effect. The nurse should monitor the client's blood pressure regularly to detect and manage any elevations effectively.

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.
