Question 4 of 5
Men who use large doses of anabolic steroids are at increased risk of:
Correct Answer: D
Rationale: Large doses of anabolic steroids (choice D) risk liver toxicity, including cholestatic jaundice and elevated AST, due to hepatic metabolism and 17-alpha-alkylated forms. Anemia (choice A) isn't typical (erythrocytosis occurs), testicular enlargement (choice B) reverses to atrophy, and hirsutism (choice C) is female-specific. Liver damage is a serious concern, necessitating monitoring in steroid abuse scenarios.
Question 5 of 5
A 58 year-old postmenopausal woman has low bone mineral density. Chronic use of which of the following medications is most likely to have contributed to this woman's osteoporosis?
Correct Answer: C
Rationale: Prednisone (choice C), a glucocorticoid, contributes to osteoporosis by inhibiting osteoblasts and increasing resorption, a common chronic use effect. Lovastatin (choice A), Metformin (choice B), and Propranolol (choice D) don't significantly affect bone density. Prednisone's impact is well-documented.
