Answer to Question 1

ANS: B
Covering the area where the patch is placed with a clear plastic wrap and taping it in place is appropriate. The ointment is not applied to the lower extremities, including the legs. The ointment should not be rubbed into the skin. Shaving is not recommended prior to application because of possible skin irritation.

Answer to Question 2

ANS: B
By inhibiting smooth muscle contraction, the calcium channel blockers dilate blood vessels and decrease resistance to blood flow. Dilation of peripheral vessels reduces the workload of the heart. Calcium channel blockers are not given to decrease heart rate in patients with angina. Calcium channel blockers do not increase cardiac contractility or promote fluid excretion.
