Question

When educating a group of nursing students on the mechanism of action of various antiarrhythmic drugs, the nurse identifies which of the following drugs as inhibiting the beta-adrenergic receptors of the heart and kidney?

A) Propafenone
B) Amiodarone
C) Disopyramide
D) Acebutolol

Answer 1

Acebutolol inhibits the beta-adrenergic receptors of the heart and kidney by blocking the action of norepinephrine (NE) on the beta-1 receptor.

Step-by-step explanation:

The drug that inhibits the beta-adrenergic receptors of the heart and kidney is D) Acebutolol. Acebutolol is a beta blocker that works by blocking the action of norepinephrine (NE) on the beta-1 receptor. By blocking these receptors, acebutolol slows down the heart rate and reduces the strength of contractions in the heart, thereby inhibiting the beta-adrenergic receptors of the heart and kidney.
