Question 1 of 5
A nurse is talking with a client who has been taking levothyroxine to treat hypothyroidism. The nurse should instruct the client to avoid taking which of the following over-the-counter medications within 4 hr of taking levothyroxine?
Correct Answer: D
Rationale: The correct answer is D: Calcium supplements. Calcium can interfere with the absorption of levothyroxine, reducing its effectiveness. It is recommended to avoid taking calcium supplements within 4 hours of levothyroxine to ensure proper absorption. Fish oil supplements (
A), bulk-forming laxatives (
B), and oral antihistamines (
C) do not typically interfere with levothyroxine absorption, so they are safe to take without waiting 4 hours.
