1. Which phase of pharmacokinetics is most significantly impacted by a patient with severe
hypoalbuminemia?
A. Absorption
B. Metabolism
C. Distribution
D. Excretion
Answer: C
Conceptual Explanation: Distribution is heavily dependent on protein binding. Albumin is
the primary binding protein; low levels increase the free fraction of protein-bound drugs,
potentially leading to toxicity.
2. A drug has a half-life of 6 hours. If the patient is at steady state, how long will it take for
the drug to be essentially eliminated from the body after the last dose?
A. 24 to 30 hours
B. 12 hours
,C. 6 hours
D. 48 to 60 hours
Answer: A
Conceptual Explanation: It takes approximately 4 to 5 half-lives for a drug to reach steady
state or to be eliminated. 6 hours x 4 = 24 hours; 6 hours x 5 = 30 hours.
3. Which of the following describes the ‘First-Pass Effect’?
A. The absorption of a drug through the gastric mucosa.
B. The binding of a drug to plasma proteins in the systemic circulation.
C. The metabolism of an orally administered drug by liver enzymes before reaching
systemic circulation.
D. The rapid excretion of a drug by the kidneys immediately after administration.
Answer: C
Conceptual Explanation: The first-pass effect occurs when a drug is metabolized by the
liver via the portal vein before it reaches the rest of the body, reducing its bioavailability.
4. An agonist is defined as a drug that:
A. Binds to a receptor and prevents its activation.
B. Binds to a receptor and produces a biological response.
C. Blocks the effect of an endogenous ligand.
, D. Chemically neutralizes another drug in the bloodstream.
Answer: B
Conceptual Explanation: Agonists mimic the action of endogenous ligands to activate
receptors and produce a response.
5. What is the primary mechanism of ‘Zero-Order’ elimination kinetics?
A. The rate of elimination is proportional to the plasma concentration.
B. The drug is cleared exclusively by the lungs.
C. The rate of elimination is constant regardless of the plasma concentration.
D. The half-life remains constant as the dose increases.
Answer: C
Conceptual Explanation: In zero-order kinetics, the metabolic enzymes are saturated, so a
constant amount of drug is eliminated per unit of time (e.g., alcohol).
6. A patient is taking a drug that is a known CYP3A4 inducer. How will this likely affect a
second drug metabolized by the same enzyme?
A. Increased plasma levels of the second drug.
B. Decreased plasma levels of the second drug.
C. No change in plasma levels.
D. Increased risk of allergic reaction.
