Question

a nurse is caring for a client who has a new prescription for propranolol to treat a tachydysrhythmia. the nurse should instruct the client to avoid taking which of the following types of over-the-counter medication while taking propranolol? antihistamines potassium supplements nsaids vitamin c

Explanation:

Propranolol is a beta - blocker. Antihistamines can have a sedative effect and when combined with beta - blockers, they can cause an increased risk of bradycardia (slow heart rate) and hypotension (low blood pressure) due to their combined effects on the cardiovascular and nervous systems. Potassium supplements, NSAIDs, and Vitamin C do not have a significant interaction with propranolol that would require avoidance in the same way antihistamines do.

Answer:

Antihistamines
