Answer to Question 1

ANS: 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

ANS: A
Patients taking leuprolide may initially experience an increase in cancer symptoms until GnRH receptors in the pituitary become desensitized. Increasing the dose is not indicated, and these symptoms do not warrant surgical castration. They do not reflect a worsening of this patient's cancer symptoms.
