A nurse is reviewing the medication list of a client who has a new prescription for tetracycline. The nurse should instruct the client to take which of the following medications 3 hr before or after taking the tetracycline?
Correct answer
B
Rationale
The correct answer is B: Antacid. Tetracycline can bind to certain substances, like calcium in antacids, reducing its absorption. By taking the antacid 3 hours before or after tetracycline, the client can ensure optimal absorption of the antibiotic. Choice A, hydrochlorothiazide, does not interact significantly with tetracycline. Choices C and D also do not have significant interactions with tetracycline.
