The nurse is caring for a patient diagnosed with unstable angina who is prescribed metoprolol. The patient asks the nurse, "Why do I have to take this medication?" What response by the nurse is most accurate?

"This medication will decrease how hard your heart works."

"It is prescribed to dilate your coronary arteries."

"It will prevent any irregular heartbeats."

"This medication makes your heart beat more forcefully."

Answer and Explanation

The Correct Answer is A

A. Metoprolol, a beta-blocker, decreases the heart rate and reduces myocardial oxygen demand by lowering the workload on the heart, which is beneficial for managing unstable angina.

B. While metoprolol has some vasodilatory effects, its primary action is to reduce heart workload, not to dilate coronary arteries.

C. Although beta-blockers can reduce the risk of arrhythmias, the main purpose in angina management is to decrease cardiac workload.

D. Metoprolol does not make the heart beat more forcefully; instead, it decreases the force of contraction to reduce myocardial oxygen consumption.
