单项选择题
Before undergoing a subtotal thyroidectomy, a client receives potassium iodide (Lugol’s solution) and propylthiouracil (PTU). The nurse would expect the client’s symptoms to subside（）
A. in a few days.
B. in 3 to 4 months.
C. immediately.
D. in 1 to 2 weeks.
答案
参考答案：D
解析：

PTU blocks the conversion of thyroxine to triiodothyronine, the more biologically active thyroid hormone. PTU effects are also seen in 1 to 2 weeks. To relieve symptoms of hyperthyroidism in the interim, clients are usually given a beta-adrenergic blocker such as propranolol.
