Answer to Question 1

B
Feedback:
Therapeutic lifestyle changes to lower serum cholesterol, including exercise, smoking cessation, change in diet, and drug therapy, are recommended to lower serum cholesterol. The patient with an elevated serum cholesterol should increase exercise and not increase rest periods. The patient should consume low-fat dairy products and avoid whole milk. Organic foods are not specifically recommended.

Answer to Question 2

B, C
Feedback:
Immature organ systems and changing body compositions mean that drugs affect children differently. Causes of pharmacodynamic variability across the lifespan include differences in body composition, immature systems, and genetic makeup. Total body water, fat stores, and protein amounts change throughout childhood and greatly influence the effectiveness of drugs in the pediatric population. Children are indeed less able to describe adverse effects, but this is not a pharmacodynamics variation. Differences in the function of the immune system are not noted to significantly influence pharmacodynamics.
