Answer to Question 1

B
Feedback:
Beta-adrenergic agonists are less effective in older adults as a result of the decreased function of the beta-receptor system. The potential for hepatotoxicity is not increased, and a beta-blocker is not indicated. Serial blood work is not necessary.

Answer to Question 2

C
