Answer to Question 1

B
No clear evidence indicates that antioxidant vitamins lead to a reduced risk of cancer. Some ob-servational studies show a link between the consumption of foods high in antioxidants and lower cancer rates, but this link may be related to other components of these diets, such as the high fi-ber also found in such foods. Some vitamins are linked to higher cancer rates when consumed in both too-low and too-high amounts.

Answer to Question 2

B
Hydralazine can cause severe reflex tachycardia; a beta blocker is usually given to counter this effect. Postural hypotension is minimal with hydralazine. Patients should be taught to report joint pain, which indicates an SLE syndrome and requires discontinuation of the drug. Minoxidil can cause excessive hair growth, not hydralazine.
