PMHNP Psychopharmacology Success
NR-546 Midterm Exam 2026: Advanced
Pharmacology Psychopharmacology for
PMHNP
100 Practice Questions with Answers and
Rationales
SECTION 1: NEUROBIOLOGY &
NEUROTRANSMITTER SYSTEMS (Questions
1-20)
Question 1:
Which neurotransmitter pathway projects
from the raphe nuclei in the brainstem to
,the prefrontal cortex and is primarily
responsible for mood regulation, sleep, and
appetite?
A. Dopaminergic nigrostriatal pathway
B. Noradrenergic locus coeruleus pathway
C. Serotonergic raphe-prefrontal pathway
D. Cholinergic basal forebrain pathway
Correct Answer: C
Rationale: The serotonergic (5-HT) pathway
originates in the dorsal raphe nuclei (DRN)
and median raphe nuclei, projecting widely
to the prefrontal cortex, limbic system, and
spinal cord. This pathway regulates mood
(depression/anxiety), sleep-wake cycles,
appetite, sexual function, and pain
modulation. SSRIs and SNRIs enhance
serotonin transmission here. The
,nigrostriatal pathway (A) involves dopamine
and motor control; the locus coeruleus (B) is
the origin of noradrenergic projections; the
basal forebrain cholinergic system (D) is
involved in memory and cognition .
Question 2:
Which brain region is primarily responsible
for executive function, decision-making, and
is implicated in the negative symptoms of
schizophrenia?
A. Amygdala
B. Hippocampus
C. Prefrontal cortex
D. Nucleus accumbens
Correct Answer: C
, Rationale: The prefrontal cortex (PFC)
governs executive function, working
memory, impulse control, and emotional
regulation. Hypofunction of the
mesocortical dopamine pathway (VTA →
PFC) is linked to negative symptoms of
schizophrenia (avolition, alogia, flat affect).
The amygdala (A) processes fear and
anxiety; the hippocampus (B) is critical for
memory formation; the nucleus accumbens
(D) is the core reward center .
Question 3:
Which event directly triggers synaptic
vesicle fusion and neurotransmitter release
at the axon terminal?
