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?
Correct Answer: B
Rationale: The correct answer is B: Antacid. Tetracycline should be taken on an empty stomach for optimal absorption. Antacids containing calcium, aluminum, magnesium, or iron can bind to tetracycline and decrease its absorption.
Therefore, the client should take the antacid 3 hours before or after taking tetracycline to avoid this interaction.
Choice A (Hydrochlorothiazide) does not have a significant interaction with tetracycline.
Choices C (Lovastatin) and D (Acetaminophen) do not require specific timing in relation to tetracycline.
