Question 1 of 5

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?

A. Hydrochlorothiazide B. Antacid C. Acetaminophen D. Lovastatin

Correct Answer: B

Rationale: The correct answer is B: Antacid. Tetracycline can bind to divalent or trivalent cations, reducing its absorption. Antacids contain cations such as calcium, magnesium, or aluminum, which can chelate with tetracycline and decrease its effectiveness. Instructing the client to take the antacid 3 hr before or after tetracycline helps to avoid this interaction. Hydrochlorothiazide (
A), Acetaminophen (
C), and Lovastatin (
D) do not have significant interactions with tetracycline.
