Section 1: Pharmacokinetics & Pharmacodynamics – ADME, First-Pass, Half-Life,
Therapeutic Index, Agonists/Antagonists
Q1: Pharmacokinetics is BEST defined as the study of:
A. how the body processes a drug (ADME) [CORRECT]
B. how a drug affects the body
C. drug naming
D. drug pricing
Correct Answer: A
Rationale: Pharmacokinetics describes absorption, distribution, metabolism, and excretion.
Q2: The PRIMARY site of drug metabolism is the:
A. liver [CORRECT]
B. kidney
C. lung
D. stomach
Correct Answer: A
Rationale: The liver metabolizes most drugs via CYP450 enzymes.
Q3: Cytochrome P450 (CYP450) enzymes are primarily responsible for:
A. drug metabolism [CORRECT]
B. drug absorption
C. renal excretion
D. protein binding
Correct Answer: A
Rationale: CYP450 enzymes metabolize drugs in the liver.
Q4: The PRIMARY organ for excretion of most drugs is the:
A. kidneys [CORRECT]
B. liver
C. lungs
D. skin
Correct Answer: A
Rationale: Most drugs and metabolites are excreted renally.
Q5: The first-pass effect refers to:
A. hepatic metabolism of an oral drug before it reaches systemic circulation [CORRECT]
B. the first dose given
C. rapid renal clearance
D. the drug's peak effect
Correct Answer: A
Rationale: Oral drugs pass through the liver first, reducing systemic availability.
Q6: Bioavailability is BEST defined as:
A. the percentage of an administered dose reaching systemic circulation [CORRECT]
B. the speed of absorption
C. the degree of protein binding
D. the duration of action
Correct Answer: A
Rationale: Bioavailability is the fraction of the dose reaching circulation unchanged.

Q7: Half-life is the time required for:
A. plasma drug concentration to decrease by 50% [CORRECT]
B. the drug to reach peak
C. complete elimination
D. receptor binding
Correct Answer: A
Rationale: Half-life is the time for concentration to fall by half.
Q8: A drug has a half-life of 8 hours. After 24 hours, what fraction remains?
A. 12.5% (three half-lives) [CORRECT]
B. 50%
C. 25%
D. 0%
Correct Answer: A
Rationale: 24 hours = 3 half-lives: 100→50→25→12.5%.
Q9: The therapeutic index is:
A. the ratio of toxic dose to therapeutic dose [CORRECT]
B. the number of doses needed
C. the time to peak
D. the protein-binding ratio
Correct Answer: A
Rationale: Therapeutic index = toxic dose / therapeutic dose.
Q10: Which drug has a NARROW therapeutic index requiring close monitoring?
A. Digoxin [CORRECT]
B. Acetaminophen
C. Vitamin C
D. Fiber supplement
Correct Answer: A
Rationale: Digoxin and lithium have narrow therapeutic indices.
Q11: An AGONIST drug:
A. activates a receptor to produce a response [CORRECT]
B. blocks a receptor
C. has no effect
D. destroys receptors
Correct Answer: A
Rationale: Agonists activate receptors.
Q12: An ANTAGONIST drug:
A. blocks receptor activation [CORRECT]
B. activates receptors
C. increases receptor number
D. acts like the endogenous ligand
Correct Answer: A
Rationale: Antagonists block receptors without activating them.
