Answer to Question 1

B
Histamine receptor antagonists can be used to provide immediate symptom relief, so until the cromolyn has provided relief, they may be useful for treating symptoms. Demulcents only add moisture to the eye and do not prevent chemical mediators from causing symptoms. Glucocorti-coids are used for inflammatory disorders of the eye but are not first-line agents. Ocular decon-gestants are used to treat redness caused by minor irritants.

Answer to Question 2

C
Because the agent causes cycloplegia, which paralyzes the iris sphincter, the eyes are unable to respond to bright light, so patients should be advised to wear sunglasses until this effect wears off. Systemic side effects do occur with these agents. Tachycardia is a systemic effect and may indicate toxicity. Mydriasis is an effect of this drug, causing the eye to be unable to focus; pa-tients will have blurred vision until this effect wears off.
