SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS
(Questions 1-50)
Foundational Concepts
1. Define pharmacokinetics.
A) The impact of drugs on the body
B) The impact of the body on drugs
C) The study of drug interactions
D) The study of drug toxicity
Answer: B
Rationale: Pharmacokinetics is the impact of the body on drugs—how much of an
administered dose gets to its sites of action. It encompasses four major processes:
absorption, distribution, metabolism, and excretion. In contrast, pharmacodynamics is
the impact of drugs on the body .
2. What are the four major pharmacokinetic processes?
,A) Absorption, distribution, metabolism, excretion
B) Absorption, distribution, metabolism, elimination
C) Administration, distribution, metabolism, excretion
D) Absorption, dispersion, metabolism, excretion
Answer: A
Rationale: The four major pharmacokinetic processes are drug absorption (how the
drug enters the body), distribution (how the drug moves to target tissues), metabolism
(how the drug is broken down), and excretion (how the drug leaves the body) .
3. Define pharmacodynamics.
A) The impact of the body on drugs
B) The impact of drugs on the body
C) The study of drug interactions
D) The study of drug toxicity
Answer: B
Rationale: Pharmacodynamics is the impact of drugs on the body—the nature and
intensity of the response to the drug. It encompasses receptor binding, mechanism of
action, and dose-response relationships .
4. An agonist is a drug that:
A) Binds to a receptor and blocks it
B) Binds to a receptor and activates it
C) Alters the pH of body fluids
D) Chelates heavy metals
Answer: B
Rationale: Agonists bind and activate receptors to produce a biological response.
Antagonists bind but do not activate; they block agonist effects. Partial agonists
produce submaximal response regardless of concentration .
,5. What is the therapeutic index?
A) The ratio of effective dose to lethal dose
B) The ratio of toxic dose to effective dose (TD50/ED50)
C) The time required for a drug to reach steady state
D) The fraction of drug that reaches systemic circulation
Answer: B
Rationale: The therapeutic index (TI) = TD50/ED50. A narrow TI indicates a small margin
between therapeutic and toxic doses, requiring careful therapeutic drug monitoring.
Examples include digoxin, phenytoin, warfarin, and lithium .
6. A drug with a narrow therapeutic index would require:
A) Less frequent monitoring
B) Careful therapeutic drug monitoring
C) Larger doses
D) Once-daily dosing
Answer: B
Rationale: A drug with a narrow therapeutic index requires careful therapeutic drug
monitoring because the difference between therapeutic and toxic levels is small.
Examples include digoxin, phenytoin, and warfarin .
7. A drug has a half-life of 6 hours. Approximately how long will it take to reach
94% of steady state?
A) 12 hours
B) 24 hours
C) 30 hours
D) 48 hours
, Answer: C
Rationale: Steady state is reached after approximately 4-5 half-lives. 4 × 6 = 24 hours
(≈94% of steady state); 5 × 6 = 30 hours (≈97%). The closest answer is 30 hours .
8. After 1 half-life, what percentage of drug remains?
A) 25%
B) 50%
C) 75%
D) 90%
Answer: B
Rationale: After one half-life, 50% of the drug remains in the body. After two half-lives,
25% remains; after three half-lives, 12.5% remains; after four half-lives, 6.25% remains .
9. A drug has a half-life of 12 hours. How many hours to reach steady state?
A) 24 hours
B) 48 hours
C) 60 hours
D) 72 hours
Answer: C
Rationale: Steady state is reached after approximately 4-5 half-lives. 12 hours × 5 = 60
hours (2.5 days) for 93-97% of steady-state concentration .
10. The volume of distribution (Vd) is defined as:
A) Volume of blood cleared of drug per unit time
B) The apparent volume into which a drug distributes (dose/plasma concentration)
