A nurse is caring for a client who has Graves' disease and is to start therapy with propylthiouracil. The nurse should expect which of the following outcomes?

  • A. Decreased heart rate
  • B. Decreased WBC count
  • C. Increased Hgb
  • D. Increased blood pressure
Correct Answer: A

Rationale: The correct answer is A: Decreased heart rate. Propylthiouracil is an antithyroid medication used to treat hyperthyroidism in conditions like Graves' disease. It works by inhibiting the production of thyroid hormones. Since hyperthyroidism can cause an increased heart rate due to the excess thyroid hormones, the expected outcome of propylthiouracil therapy is a decreased heart rate as it helps normalize thyroid hormone levels. The other choices are incorrect because propylthiouracil does not directly affect WBC count (B), Hgb levels (C), or blood pressure (D) in the context of treating hyperthyroidism.
