Answer to Question 1

ANS: A, E
Studies to determine the potential benefits of vitamin E supplements show a decreased risk of colds in elderly patients when vitamin E is combined with vitamin C, beta-carotene, zinc, and copper, and a potential delay in the progression of macular degeneration. Vitamin E may actually increase the risk of bleeding. Studies have not shown a decrease in the risk of Alzheimer's disease or cardiovascular disease.

Answer to Question 2

ANS: B
Safe and maintainable weight loss should be about 10 of body weight in 6 months (i.e., 28 pounds for this patient). A loss of 50 pounds in 6 months is unrealistic for this patient. Advising the patient to aim for a weight loss of 80 pounds in the first 6 months is less realistic than a reduction of 50 pounds and may actually harm the patient. Weight loss of more than 20 pounds in 6 months is not dangerous, because it falls within the guideline of 10 of body fat (i.e., 28 pounds for this patient).
