A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:

  • A. Decrease thyroid hormone production
  • B. Increase thyroid hormone production
  • C. Suppress the immune system
  • D. Prevent thyroid storm
Correct Answer: A

Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.
