Question 1 of 5
A nurse is taking a medication history from a client who has a new prescription for levothyroxine. The nurse should instruct the client to wait 4 hr after taking levothyroxine before taking which of the following supplements?
Correct Answer: D
Rationale: The correct answer is D: Calcium. Levothyroxine absorption can be decreased by calcium when taken together. Calcium can bind to levothyroxine in the gastrointestinal tract, reducing its absorption. Waiting 4 hours after taking levothyroxine before consuming calcium ensures optimal absorption of levothyroxine. Ginkgo biloba, zinc, and vitamin C do not interfere significantly with levothyroxine absorption, making choices A, B, and C incorrect in this scenario.
