Correct Answer: A

Rationale: Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia as an adverse effect. Hyperkalemia can result in muscle weakness and cardiac dysrhythmias, making it essential for the nurse to monitor potassium levels closely when a client is on Spironolactone.

Correct Answer: A

Rationale: Orthostatic hypotension is a known adverse effect of MAOIs, such as Phenelzine. It is characterized by a drop in blood pressure upon standing, which can lead to dizziness or fainting. Monitoring for orthostatic hypotension is crucial when administering MAOIs to prevent potential complications.

Correct Answer: A

Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin can lead to toxicity, which can manifest as various signs and symptoms, including bradycardia. Monitoring the client's heart rate closely is crucial to detect and manage potential toxicity early.

Correct Answer: A

Rationale: Losartan, an angiotensin II receptor blocker (ARB), can cause hyperkalemia. The nurse should monitor the client's serum potassium levels closely because Losartan can increase potassium levels, potentially leading to serious complications such as arrhythmias.

Correct Answer: C

Rationale: Methylnaltrexone is an opioid antagonist used to treat severe constipation unresponsive to laxatives in opioid-dependent clients. It functions by blocking the mu opioid receptors in the gastrointestinal tract, helping alleviate constipation associated with opioid use.
