aligned with the PMHNP curriculum to ensure exam readiness.
SECTION 1: NEUROBIOLOGY & PSYCHOPHARMACOLOGY
(Questions 1-35)
,Question 1
The biopsychosocial model in psychiatry emphasizes that mental disorders result
from:
A. Genetic mutations only
B. Social learning only
C. The complex interaction of biological, psychological, and social factors
D. Unconscious conflict only
Correct answer: C
RATIONALE: The biopsychosocial model is a core tenet of psychiatric
nursing — that mental disorders result from the complex interaction of biological,
psychological, and social factors. This model guides comprehensive assessment
and treatment planning in PMHNP practice.
Question 2
Which neurotransmitter is primarily associated with movement, attention, and
learning, and is often implicated in schizophrenia?
A. Dopamine
B. GABA
C. Norepinephrine
D. Serotonin
Correct answer: A
RATIONALE: Dopamine is involved in movement, attention, and learning.
The dopamine hypothesis of schizophrenia suggests that excess dopamine activity
in certain brain pathways contributes to positive symptoms such as hallucinations
and delusions.
Question 3
Which neurotransmitter is the major inhibitory neurotransmitter in the central
nervous system?
,A. Glutamate
B. GABA
C. Dopamine
D. Serotonin
Correct answer: B
RATIONALE: GABA (gamma-aminobutyric acid) is the major inhibitory
neurotransmitter in the central nervous system. It decreases neuronal excitability
and inhibits excitation and anxiety. Low GABA levels are associated with anxiety
disorders.
Question 4
Which neurotransmitter is the major excitatory neurotransmitter in the central
nervous system?
A. GABA
B. Glutamate
C. Dopamine
D. Serotonin
Correct answer: B
RATIONALE: Glutamate is the major excitatory neurotransmitter in the CNS,
important for memory, cognition, and mood. Excessive glutamate activity can
cause excitotoxicity and neuronal damage.
Question 5
Which neurotransmitter is involved in mood, sleep, appetite, and
impulsive/aggressive behavior?
A. Dopamine
B. Acetylcholine
C. Serotonin
D. Norepinephrine
Correct answer: C
, RATIONALE: Serotonin plays a key role in mood regulation, sleep, appetite,
and impulsive/aggressive behavior. Low serotonin levels are associated with
depression and anxiety disorders, particularly obsessive-compulsive disorder.
Question 6
The HPA axis (hypothalamic-pituitary-adrenal) is involved in:
A. Memory consolidation
B. Stress response and cortisol regulation
C. Motor control
D. Visual processing
Correct answer: B
RATIONALE: The HPA axis is the body‘s central stress response system.
Dysregulation of the HPA axis is implicated in depression, PTSD, and anxiety
disorders.
Question 7
The amygdala is primarily responsible for:
A. Memory formation and learning
B. Emotional processing, fear, and anxiety
C. Motor coordination
D. Language comprehension
Correct answer: B
RATIONALE: The amygdala is involved in anxiety, anger, fear, and emotional
memories. It registers emotional meaning to stimuli and adjusts behavior to social
context. The amygdala is hyperactive in anxiety disorders and PTSD.
Question 8
The hippocampus is primarily responsible for:
