Answer to Question 1

Correct Answer: 4
Rationale 1: Peak plasma level is the highest plasma level achieved by a single dose when the elimination rate of the drug equals the absorption rate.
Rationale 2: Drug half-life is the time required for the elimination process to reduce the concentration of the drug to one-half of what it was at initial administration.
Rationale 3: Onset of action is the time after administration when the body initially responds to the drug.

Answer to Question 2

Correct Answer: 3
Rationale 1: Absorption is the process by which a drug passes into the bloodstream.
Rationale 2: Distribution is the transportation of a drug from its site of absorption to its site of action.
Rationale 3: Biotransformation, also called detoxification or metabolism, is a process by which a drug is converted to a less active form. Most biotransformation takes place in the liver. Biotransformation can be altered if a person has an unhealthy liver.
Rationale 4: Excretion is the process by which metabolites and drugs are eliminated from the body. Most drug metabolites are eliminated by the kidneys via the urine.
