,1. A drug's bioavailability is defined as:
- A) The rate at which a drug is absorbed.
- B) The fraction of an administered dose that reaches systemic
circulation.
- C) The time it takes for a drug to reach peak plasma
concentration.
- D) The concentration of a drug in the bloodstream.
- Correct ANS: B
- Rationale: Bioavailability is the proportion of a drug that
enters systemic circulation when introduced into the body and is
available for therapeutic effect.
2. Which of the following drug classes is primarily used to lower

3. Which pharmacokinetic phase involves the metabolism of a
drug?
- A) Absorption
- B) Distribution
- C) Metabolism
- D) Excretion
- Correct ANS: C
- Rationale: Metabolism is the phase where the body
chemically alters the drug, often resulting in its conversion to a
more water-soluble compound for excretion.
4. For which of the following conditions is warfarin prescribed?
- A) Hypertension
