Answer to Question 1

B
Pharmacokinetics is the study of the action of drugs in the body and may be thought of as what the body does to the drug. Factors such as age, race, and gender may change the way the body acts to metabolize and excrete a drug. Bioavailability refers to the amount of drug available at the site of action. Pharmacodynamics is the study of the effects of drugs on the body. Anatomy and physiology is a basic understanding of how the body functions.

Answer to Question 2

A
PAs commonly have co-signature requirements and work under physician supervision.
