Answer to Question 1

C
Sunscreens should be reapplied after swimming and with profuse sweating. Most sunscreens should be applied at least 30 minutes before going outdoors, but some require application 2 hours before exposure. Clouds do not protect from all UV rays. UV radiation can penetrate at least several centimeters of clear water.

Answer to Question 2

A
After cardioversion for atrial flutter, patients may continue to need long-term therapy with either a class IC agent or a class III agent to prevent recurrence. Patients undergoing DC cardioversion need to take warfarin 3 to 4 weeks before the procedure and for several weeks afterward. Beta blockers are not indicated for postprocedural prophylaxis. Class IC and class III agents are anti-dysrhythmic drugs.
