Answer to Question 1

A
Feedback:
The total amount of drug absorbed and the resulting plasma drug concentrations from transdermal estrogen can increase during exposure to heat, so patients should be advised to avoid prolonged sun exposure in the area of the patch. The application of heat at the patch site will increase effectiveness. The medication's exposure to sunlight will not increase the risk of breast cancer. The medication's exposure to cold will not change its effectiveness.

Answer to Question 2

C
Feedback:
For disopyramide, the Food and Drug Administration (FDA) has issued a black box warning because of the drug's known prodysrhythmic properties. It is not specifically linked to chest pain, valvular regurgitation, or renal failure.
