Question

a nurse is caring for a client who has a new prescription for verapamil to treat atrial fibrillation. the nurse should instruct the client to avoid drinking grapefruit juice while taking verapamil because it can cause the client to experience which of the following conditions? tachycardia dehydration diarrhea hypotension

Explanation:

Verapamil is a calcium channel blocker used for atrial fibrillation. Grapefruit juice inhibits the enzyme that metabolizes verapamil, increasing its blood levels. Verapamil lowers blood pressure and heart rate; increased levels can cause excessive hypotension. Tachycardia is unlikely (verapamil slows heart rate), dehydration and diarrhea aren't direct effects of verapamil - grapefruit juice interaction.

Answer:

D. Hypotension
