NSG 552 EXAM 1 – PSYCHOPHARMACOLOGY WILKES
UNIVERSITY 2026/2027 COMPLETE (150) CURRENT
TESTING QUESTIONS AND CORRECT ANSWERS WITH
DETAILED RATIONALES.
PSYCHOPHARMACOLOGY
Prepare effectively for the NSG 552 Exam 1 with this focused study resource. It
supports review of key nursing concepts, clinical assessment, evidence-based
practice, patient care, and course-specific knowledge relevant to advanced nursing
education. Use the material to reinforce your understanding, review important topics,
and identify areas that may require additional study. This resource is suited for nursing
students, advanced practice nursing learners, and candidates preparing for the NSG
552 examination.
MULTIPLE CHOICE.
SECTION 1: FOUNDATIONAL CONCEPTS – PHARMACOKINETICS &
PHARMACODYNAMICS (Questions 1–35)
Question #1
The study of what the body does to a drug, including absorption, distribution,
metabolism, and excretion, is known as:
A. Pharmacodynamics
B. Pharmacokinetics
C. Psychopharmacology
D. Pharmacogenomics
Correct Answer: B
Rationale: Pharmacokinetics describes how the body processes a drug—
specifically its absorption, distribution, metabolism, and excretion (ADME).
Pharmacodynamics, conversely, studies what the drug does to the body.

Question #2
The study of what a drug does to the body, including its mechanism of action
and therapeutic effects, is known as:
A. Pharmacokinetics
B. Pharmacodynamics
C. Psychopharmacology
D. Pharmacotherapeutics
Correct Answer: B
Rationale: Pharmacodynamics focuses on the biochemical and
physiological effects of drugs and their mechanisms of action at the
receptor level.
Question #3
The study of the use of psychotropic medications in the treatment of
psychiatric disorders is defined as:
A. Pharmacokinetics
B. Pharmacodynamics
C. Psychopharmacology
D. Neuropharmacology
Correct Answer: C
Rationale: Psychopharmacology is the specific field that examines how
psychotropic medications affect the brain and behavior to treat psychiatric
disorders.
Question #4
A drug that binds to a receptor and produces a full biologic response is called
a(n):
A. Antagonist
B. Partial agonist
C. Agonist
D. Inverse agonist
, Page 3 of 57
Correct Answer: C
Rationale: An agonist binds to a receptor and fully activates it, producing
the maximum biologic response.
Question #5
A drug that binds to a receptor but does not fully activate it, producing only a
partial response, is called a(n):
A. Antagonist
B. Partial agonist
C. Full agonist
D. Inverse agonist
Correct Answer: B
Rationale: A partial agonist binds to the receptor but has lower intrinsic
activity than a full agonist, producing a submaximal response even when all
receptors are occupied. Aripiprazole is an example.
Question #6
A drug that binds to a receptor and blocks it, preventing a biologic response, is
called a(n):
A. Agonist
B. Partial agonist
C. Antagonist
D. Inverse agonist
Correct Answer: C
Rationale: An antagonist binds to a receptor without activating it, thereby
blocking agonists from binding and preventing a biologic response.
Question #7
A drug that binds to the same receptor as an agonist but induces an opposite
biological response is called a(n):
, Page 4 of 57
A. Agonist
B. Partial agonist
C. Antagonist
D. Inverse agonist
Correct Answer: D
Rationale: An inverse agonist binds to the same receptor site as an
agonist but produces the opposite effect, reducing constitutive receptor
activity below baseline.
Question #8
The process of a drug moving from the site of administration into the
bloodstream is called:
A. Distribution
B. Absorption
C. Metabolism
D. Excretion
Correct Answer: B
Rationale: Absorption is the primary pharmacokinetic process where a
drug moves from its entry point into systemic circulation. This process is
influenced by the drug's lipid solubility and the pH of the environment.
Question #9
Which cytochrome P450 enzyme is primarily responsible for the metabolism
of approximately 25% of all psychiatric medications, including many
antidepressants and antipsychotics?
A. CYP3A4
B. CYP1A2
C. CYP2D6
D. CYP2C19
Correct Answer: C
Rationale: CYP2D6 is a highly polymorphic enzyme that plays a critical
