SECTION 1: BASIC PRINCIPLES OF PHARMACOLOGY
(Questions 1–30)
Question 1: A drug that binds to a receptor and produces a maximal
response is called a:
A) Partial agonist
B) Antagonist
C) Full agonist
D) Inverse agonist
Correct Answer: C) Full agonist
Rationale: A full agonist binds to a receptor and produces a maximal biologic
response. A partial agonist (A) produces a submaximal response even at full
receptor occupancy. An antagonist (B) binds but does not activate the
receptor. An inverse agonist (D) produces the opposite effect of an agonist.
,Question 2: A patient asks how a medication taken by mouth produces an
effect in the body. The nurse explains that the process by which a drug is
absorbed, distributed, metabolized, and excreted is known as:
A) Pharmacodynamics
B) Pharmacotherapeutics
C) Pharmacokinetics
D) Pharmacogenomics
Correct Answer: C) Pharmacokinetics
Rationale: Pharmacokinetics is the study of drug movement throughout the
body, including absorption, distribution, metabolism, and excretion (ADME).
Pharmacodynamics (A) is what the drug does to the body.
Pharmacotherapeutics (B) is the use of drugs to treat disease.
Pharmacogenomics (D) is the study of how genes affect drug response.
Question 3: The percentage of an administered drug that is available for
activity is known as:
A) Bioavailability
B) Bioequivalence
C) Therapeutic index
D) Half-life
Correct Answer: A) Bioavailability
Rationale: Bioavailability is the percentage of administered drug that reaches
the systemic circulation and is available for activity. Bioequivalence (B)
compares two formulations. Therapeutic index (C) is the ratio of toxic dose to
therapeutic dose. Half-life (D) is the time for drug concentration to decrease
by 50%.
, Question 4: Two drugs that produce an effect equal to the sum of their
individual effects are said to have:
A) Synergism
B) Potentiation
C) Additive effect
D) Antagonism
Correct Answer: C) Additive effect
Rationale: An additive effect occurs when the combined effect of two drugs
equals the sum of their individual effects (e.g., acetaminophen + ibuprofen
for pain). Synergism (A) occurs when the combined effect is greater than the
sum. Potentiation (B) occurs when one drug enhances the effect of another.
Antagonism (D) occurs when drugs oppose each other's effects.
Question 5: When the combined effect of two drugs is greater than the
sum of their individual effects, this is called:
A) Additive effect
B) Synergism
C) Potentiation
D) Antagonism
Correct Answer: B) Synergism
Rationale: Synergism results in a superadditive effect (e.g., alcohol +
benzodiazepines causing excessive CNS depression). Additive effect (A) equals
the sum. Potentiation (C) occurs when one drug enhances the effect of
another without having its own effect. Antagonism (D) opposes effects.
Question 6: A drug that is a CYP450 enzyme inducer will likely:
