Answer to Question 1

A
Timolol is a beta blocker and can precipitate bronchoconstriction when absorbed systemically. Patients with asthma will develop shortness of breath and wheezing. These symptoms are not associated with AV block, pulmonary hypertension, or sinus bradycardia.

Answer to Question 2

D
Anastrozole is used to treat ER-positive breast cancer in postmenopausal women. Because it does not block estrogen production in the ovaries, it is not effective in premenopausal women. It may cause hot flushes but is less likely to do so than tamoxifen. It is devoid of all estrogenic activity and does not promote endometrial cancer
