Answer to Question 1

B
Feedback:
The thioamide drugs inhibit synthesis of thyroid hormone. Iodine preparations inhibit the release of thyroid hormones and cause them to be stored within the thyroid gland. Propylthiouracil does not destroy part of the thyroid gland. Propylthiouracil does not suppress the anterior pituitary hormones. Propylthiouracil does not sedate the central nervous system or suppress the cardiac output.

Answer to Question 2

A
Feedback:
Deferoxamine is a parenteral drug used to remove excess iron from storage sites in the body. Penicillamine, sucralfate, and magnesium sulfate are not administered for iron toxicity.
