- A. dobutamine
- B. digoxin
- C. nicardipine
- D. amiodarone
Correct Answer: C

The nurse has provided teaching to a client regarding metoprolol. Which of the following statements by the client would indicate a correct understanding of the teaching?
- A. I should stop taking metoprolol immediately if I experience any dizziness or lightheadedness.
- B. Metoprolol works by increasing the production of angiotensin II to lower blood pressure.
- C. I should monitor my heart rate regularly as metoprolol can cause bradycardia.
- D. It's essential to take metoprolol with a high-fat meal to enhance its absorption.
Correct Answer: C
Rationale: Metoprolol, a beta-blocker, can cause bradycardia, so monitoring heart rate is correct. Stopping abruptly, increasing angiotensin II, or requiring high-fat meals are incorrect.

- A. esmolol
- B. dexamethasone
- C. heparin

- B. record their daily urinary output.
- C. weigh themselves daily.
- D. take their blood pressure and pulse daily.
Correct Answer: C
Rationale: Bumetanide, a loop diuretic, requires daily weight monitoring to assess fluid status in CHF. Protein intake, urinary output records, or vital signs monitoring are less critical.
