Answer to Question 1

ANS: C
The thyroid gland absorbs high concentrations of radioactive iodine, which destroys the hyperactive thyroid tissue with essentially no damage to other tissues in the body. Radioactive iodine does not stimulate hormone synthesis, increase hormone storage, or replace deficient hormones.

Answer to Question 2

ANS: C
Patients typically treated with radioactive iodine therapy are those who are beyond childbearing years, those with severe complicating diseases (e.g., heart disease), those with recurrent hyperthyroidism after previous thyroid surgery, those who are poor surgical risks, and those who have unusually small thyroid glands. Women of childbearing age should not be treated with radioactive iodine. Hypothyroidism and myxedema are not treated with radioactive iodine.
