LATEST NSG 552 PSYCHOPHARMACOLOGY EXAMS 1, 2 & 3
QUESTIONS AND CORRECT ANSWERS PLUS RATIONALES
CORE DOMAINS
Foundations of Psychopharmacology (Pharmacokinetics &
Pharmacodynamics)
Neurotransmitters, Receptors & Brain Pathways
Antidepressants (SSRIs, SNRIs, TCAs, MAOIs, Atypicals)
Anxiolytics, Hypnotics & Buspirone
Antipsychotics & Movement Disorders
Mood Stabilizers (Lithium & Anticonvulsants)
Substance Use Disorder Pharmacotherapy
Special Populations & Adverse Effects
INTRODUCTION
The NSG 552 Psychopharmacology Exams 1, 2 & 3 assess the
competency of graduate psychiatric-mental health nurse practitioner
students at Wilkes University. This comprehensive assessment evaluates
knowledge across critical domains including pharmacokinetics and
pharmacodynamics, neurotransmitter systems, antidepressant and
antipsychotic pharmacology, mood stabilizers, anxiolytics, and
substance use disorder pharmacotherapy. The examinations employ
multiple-choice and scenario-based questions that require candidates to
demonstrate applied clinical judgment and decision-making skills
essential for safe prescribing. Emphasis is placed on receptor
mechanisms, CYP450 drug interactions, adverse effect monitoring, and
evidence-based medication selection. Successful completion validates
,the candidate's readiness to prescribe and manage psychotropic
medications in advanced practice.
SECTION ONE: QUESTIONS 1–100
Question 1
What is the definition of psychopharmacology?
A) The study of how the body processes drugs
B) The study of psychotropic medications in the treatment of psychiatric
disorders
C) The study of drug-receptor binding only
D) The study of herbal supplements for mental health
B) The study of psychotropic medications in the treatment of
psychiatric disorders
RATIONALE: Psychopharmacology focuses on how medications
affect mood, behavior, and cognition to manage mental health
conditions. Pharmacokinetics is the study of how the body processes
drugs.
Question 2
Which term describes the study of what the body does to a drug?
A) Pharmacodynamics
B) Pharmacokinetics
C) Pharmacogenetics
D) Pharmacotherapy
B) Pharmacokinetics
, RATIONALE: Pharmacokinetics refers to absorption, distribution,
metabolism, and excretion (ADME)—what the body does to a drug.
Pharmacodynamics is what the drug does to the body.
Question 3
Which term describes the study of what a drug does to the body?
A) Pharmacokinetics
B) Pharmacodynamics
C) Pharmacognosy
D) Pharmacovigilance
B) Pharmacodynamics
RATIONALE: Pharmacodynamics describes drug actions at
receptors, ion channels, enzymes, and carrier proteins/reuptake pumps.
Question 4
Which pharmacokinetic process involves the conversion of a drug into
metabolites, primarily in the liver?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
C) Metabolism
RATIONALE: Metabolism (biotransformation) occurs mainly in the
liver via cytochrome P450 enzymes, converting drugs into more water-
soluble metabolites for excretion.
, Question 5
What is the primary role of cytochrome P450 enzymes in
psychopharmacology?
A) Drug absorption in the GI tract
B) Drug distribution across the blood-brain barrier
C) Drug metabolism and resulting serum levels
D) Drug excretion by the kidneys
C) Drug metabolism and resulting serum levels
RATIONALE: CYP450 enzymes metabolize drugs, affecting their
serum levels. Inhibition or induction of these enzymes causes clinically
significant drug-drug interactions.
Question 6
What is the effect of an enzyme inhibitor on drug metabolism?
A) Slows metabolism, increasing serum levels of other drugs
B) Speeds up metabolism, decreasing serum levels of other drugs
C) Has no effect on drug metabolism
D) Only affects the inhibitor drug itself
A) Slows metabolism, increasing serum levels of other drugs
RATIONALE: Enzyme inhibitors reduce CYP450 activity,
potentially causing drug accumulation and toxicity in drugs that are
substrates of that enzyme.
Question 7
What is the effect of an enzyme inducer on drug metabolism?
