Answer to Question 1

ANS: C
Local effects of timolol and other beta blockers are generally minimal, but transient ocular stinging can occur. There is no need to monitor vital signs, because this does not represent a systemic reaction. This is not a sign of angle-closure glaucoma. Antihistamines will not help.

Answer to Question 2

ANS: A
Patients using this drug should wait 15 minutes before putting in contacts, because soft contacts can absorb the drug. Even though the medication is topical, it can be absorbed systemically, causing systemic side effects such as drowsiness or lowered blood pressure. Itching and hyperemia may occur and do not indicate allergy.
