SECTION 1: DEFINITIONS & BASIC CONCEPTS (Questions 1-30)
QUESTION 1
What is the primary goal of pharmacodynamics?
A) Study of drug absorption, distribution, metabolism, and excretion.
B) Study of the biochemical and physiological effects of drugs and their
mechanisms of action.
C) Study of the formulation and compounding of pharmaceutical products.
D) Study of the economic impact of drug therapies on healthcare systems.
Correct Answer: B
Rationale:
Option B is correct. Pharmacodynamics is the study of what a drug does to
the body, including its mechanisms of action, therapeutic effects, and
side effects. Option A describes pharmacokinetics. Option C describes
pharmaceutics. Option D describes pharmacoeconomics.
1
,QUESTION 2
Which route of drug administration has the fastest onset of action?
A) Oral
B) Subcutaneous
C) Intravenous
D) Transdermal
Correct Answer: C
Rationale:
Option C is correct. Intravenous (IV) administration delivers the drug
directly into the bloodstream, achieving 100% bioavailability and the
fastest onset of action. Oral (Option A) requires absorption from the GI
tract. Subcutaneous (Option B) requires absorption from interstitial tissue.
Transdermal (Option D) provides slow, sustained absorption over time.
QUESTION 3
The term "half-life" of a drug refers to:
A) The time required for the drug to reach peak plasma concentration.
B) The time required for the body to eliminate 50% of the drug.
C) The time required for the drug to exert its maximum therapeutic effect.
D) The time required for the drug to be completely eliminated from the body.
Correct Answer: B
Rationale:
Option B is correct. Half-life (t1/2) is the time required for the plasma
concentration of a drug to decrease by 50%. It helps determine dosing
intervals. Option A describes Tmax (time to peak concentration). Option C
2
,describes onset of action. Option D would require approximately 4-5 half-
lives for complete elimination, not one half-life.
QUESTION 4
Which of the following is an example of a prodrug?
A) Morphine
B) Codeine
C) Aspirin
D) Digoxin
Correct Answer: B
Rationale:
Option B is correct. Codeine is a prodrug that is converted in the liver to
its active metabolite, morphine, which produces analgesic effects.
Option A (Morphine) is an active drug, not a prodrug. Option C (Aspirin) is
an active drug. Option D (Digoxin) is an active drug.
QUESTION 5
The first-pass effect refers to:
A) The rapid distribution of a drug to highly perfused organs.
B) The metabolism of a drug in the liver before it reaches systemic
circulation.
C) The binding of a drug to plasma proteins.
D) The excretion of a drug through the kidneys.
Correct Answer: B
Rationale:
3
, Option B is correct. The first-pass effect occurs when orally administered
drugs are metabolized by the liver before reaching systemic circulation,
reducing the bioavailability of the drug. Option A describes distribution.
Option C describes protein binding. Option D describes excretion.
QUESTION 6
A drug that has high affinity but low intrinsic activity is called a:
A) Full agonist
B) Partial agonist
C) Antagonist
D) Inverse agonist
Correct Answer: B
Rationale:
Option B is correct. A partial agonist has high affinity for the receptor
but low intrinsic activity, meaning it produces a submaximal response even
when all receptors are occupied. A full agonist (Option A) has high affinity
and high intrinsic activity. An antagonist (Option C) has affinity but zero
intrinsic activity. An inverse agonist (Option D) stabilizes the inactive
form of the receptor.
QUESTION 7
Which phase of clinical drug trials involves testing on healthy volunteers?
A) Phase I
B) Phase II
C) Phase III
D) Phase IV
