Rationale: Metoprolol is a beta-blocker that works by slowing the heart rate. Therefore, the nurse should monitor the client for bradycardia, which is a potential side effect of metoprolol. Bradycardia refers to a heart rate that is slower than normal, and it can be a concern when administering medications like metoprolol that affect heart rate.

Correct Answer: B

Rationale: Spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia. Monitoring serum potassium levels is crucial to prevent adverse effects associated with high potassium levels, such as cardiac arrhythmias.

Correct Answer: A

Rationale: Muscle pain is a common side effect of statins like simvastatin and can indicate a serious condition called rhabdomyolysis. Rhabdomyolysis is a severe condition where muscle fibers break down rapidly, releasing myoglobin into the bloodstream, which can lead to kidney damage. Therefore, it's important for the nurse to educate the client about this potential side effect and to promptly report any muscle pain to the healthcare provider.

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are crucial laboratory values to monitor the effectiveness of warfarin therapy in clients with atrial fibrillation. These values help ensure that the client is within the therapeutic range and that the anticoagulant effect of warfarin is appropriate.
