Section 1: Pharmacokinetics & Pharmacodynamics
Q1: Pharmacokinetics is best defined as:
A. What the body does to the drug (ADME) [CORRECT]
B. What the drug does to the body only
C. Only the cost of therapy
D. Only receptor affinity
Correct Answer: A
Rationale: PK = absorption, distribution, metabolism, excretion.
Q2: Pharmacodynamics describes:
A. Only renal tubular secretion
B. Only first-pass extraction
C. What the drug does to the body (effects at targets) [CORRECT]
D. Only tablet appearance
Correct Answer: C
Rationale: PD = drug effect on the body.
Q3: Steady state (~97%) with regular intermittent dosing is typically reached after about:
A. 1 half-life
B. 2 half-lives
C. 20 half-lives
D. 4 to 5 half-lives [CORRECT]
Correct Answer: D
Rationale: Rule of thumb approximately 4–5 half-lives.

Q4: A loading dose is used primarily to:
A. Avoid therapeutic levels indefinitely
B. Rapidly achieve a target concentration when needed [CORRECT]
C. Eliminate all adverse effects
D. Replace the need for maintenance dosing forever
Correct Answer: B
Rationale: Fills volume of distribution quickly.
Q5: First-pass metabolism is most relevant to:
A. IV bolus drugs exclusively
B. Topical creams only
C. Orally administered drugs undergoing hepatic extraction before systemic circulation
[CORRECT]
D. Inhaled gases with no absorption
Correct Answer: C
Rationale: Oral path through gut/liver.
Q6: A prodrug requires:
A. No metabolic activation
B. Conversion to an active form in the body [CORRECT]
C. Only renal excretion unchanged always
D. Zero membrane permeability by design
Correct Answer: B
Rationale: Inactive → active transformation.
Q7: Capacity-limited (zero-order) elimination means:
A. A constant fraction is eliminated per unit time at all concentrations
B. Elimination is instantaneous
C. No drug is ever eliminated
D. A constant amount may be eliminated per time when pathways are saturated [CORRECT]
Correct Answer: D
Rationale: Saturated kinetics (e.g., phenytoin).

Q8: An agonist at a receptor:
A. Activates the receptor after binding [CORRECT]
B. Only blocks the receptor without efficacy
C. Only increases GFR
D. Never produces a tissue response
Correct Answer: A
Rationale: Affinity + efficacy.
Q9: A competitive antagonist typically:
A. Cannot be overcome by increasing agonist concentration
B. Competes for the binding site and can often be overcome by more agonist [CORRECT]
C. Only destroys the receptor permanently in all cases
D. Has no effect on dose-response relationships
Correct Answer: B
Rationale: Surmountable antagonism.
Q10: A narrow therapeutic index implies:
A. Large separation between effective and toxic exposures
B. No need for monitoring
C. Small margin between effective and toxic doses—monitor carefully [CORRECT]
D. The drug cannot cause toxicity
Correct Answer: C
Rationale: Less room for dosing error.
