Answer to Question 1

2. It works by making the blood vessels expand..

Rationale:
Doxazosin is selective for blocking alpha1-receptors in vascular smooth muscle, which results in dilation of arteries and veins. Excreting more urine is an effect of diuretic medications. Increasing the efficiency of the heart is not an effect of doxazosin. Decreasing the release of stress hormones is not an effect of doxazosin.

Answer to Question 2

3. Eggs, whole-wheat toast with butter, Lucky Charms cereal, milk, and grapefruit juice

Rationale:
Grapefruit juice in combination with a sustained-release calcium channel blocker could result in rapid toxic overdose, which is a medical emergency. There is no food-drug interaction with calcium channel blockers and whole-wheat pancakes with syrup, and bacon, oatmeal, and orange juice. There is no food-drug interaction with calcium channel blockers and eggs, sausage, a biscuit with margarine, and cranberry juice. There is no food-drug interaction with calcium channel blockers and egg and cheese omelet, tea with sugar and lemon, hash brown potatoes, and prune juice.
