DOMAIN 1: SCIENTIFIC FOUNDATIONS
(Neurobiology, Psychopharmacology,
Pathophysiology)
1. A PMHNP is reviewing the neurobiology of major depressive disorder.
Which statement best reflects current understanding of the role of brain-
derived neurotrophic factor (BDNF) in depression pathophysiology?
A. BDNF is relevant only to anxiety disorders and has no role in mood
regulation
B. Antidepressants act solely by increasing synaptic monoamines with no
effect on neurotrophic factors
C. Reduced BDNF signaling in the hippocampus and prefrontal cortex is
associated with impaired neuroplasticity and is a target of several
antidepressant mechanisms
D. BDNF levels are consistently elevated in untreated major depression and
must be suppressed for recovery
Correct Answer: C (Reduced BDNF signaling in the hippocampus and
prefrontal cortex is associated with impaired neuroplasticity and is
a target of several antidepressant mechanisms)
Rationale: Contemporary models link stress-related reductions in BDNF to
impaired neuroplasticity in key mood-regulating circuits; many effective
treatments restore BDNF signaling. This reflects the neurotrophic hypothesis
of depression .
Teaching Point: BDNF = neuroplasticity marker; reduced in depression.

,2. A 32-year-old patient with schizophrenia exhibits predominantly negative
symptoms including avolition, alogia, and affective blunting. Which
neurobiological mechanism is most directly associated with these
symptoms?
A. Hyperactivity of the mesolimbic dopaminergic pathway
B. Hypoactivity of the mesocortical dopaminergic pathway
C. Increased glutamatergic transmission in the hippocampus
D. Hyperactivity of the nigrostriatal dopaminergic pathway
Correct Answer: B (Hypoactivity of the mesocortical dopaminergic
pathway)
Rationale: Negative symptoms of schizophrenia (avolition, alogia, affective
blunting, anhedonia) are primarily associated with hypoactivity of the
mesocortical dopaminergic pathway, which projects to the prefrontal cortex.
Mesolimbic hyperactivity is associated with positive symptoms .
Teaching Point: Negative symptoms = mesocortical hypoactivity; Positive
symptoms = mesolimbic hyperactivity.

3. A patient with generalized anxiety disorder is prescribed pregabalin. The
PMHNP understands that this medication's mechanism of action involves:
A. Positive allosteric modulation of GABA-A receptors
B. Binding to the alpha-2-delta subunit of voltage-gated calcium channels
C. Serotonin and norepinephrine reuptake inhibition
D. Partial agonism at serotonin 5-HT1A receptors
Correct Answer: B (Binding to the alpha-2-delta subunit of voltage-
gated calcium channels)
Rationale: Pregabalin binds to the alpha-2-delta subunit of voltage-gated
calcium channels, reducing calcium influx and decreasing release of
excitatory neurotransmitters (glutamate, norepinephrine, substance P) .
Teaching Point: Pregabalin = alpha-2-delta calcium channel ligand.

4. A patient is started on lamotrigine for bipolar disorder maintenance.
Which genetic polymorphism is most relevant to the risk of lamotrigine-
induced severe cutaneous adverse reactions?
A. CYP2D6
B. HLA-B*1502
C. CYP2C19
D. HLA-DQ2
Correct Answer: B (HLA-B*1502)
Rationale: The HLA-B*1502 allele is strongly associated with risk of Stevens-
Johnson syndrome and toxic epidermal necrolysis with lamotrigine and
carbamazepine, particularly in Han Chinese populations .
Teaching Point: HLA-B*1502 = SJS/TEN risk with
lamotrigine/carbamazepine.

5. A 28-year-old patient of Han Chinese descent is being initiated on
carbamazepine for bipolar disorder. Before prescribing, the PMHNP should:
A. Order HLA-B*1502 genetic testing
B. Order CYP2D6 genetic testing
C. Start at a higher dose to achieve therapeutic levels quickly
D. Avoid all anticonvulsants in this population
Correct Answer: A (Order HLA-B*1502 genetic testing)
Rationale: The FDA recommends screening for HLA-B*1502 in patients of
Asian ancestry before initiating carbamazepine due to the increased risk of
Stevens-Johnson syndrome and toxic epidermal necrolysis .
Teaching Point: Asian ancestry + carbamazepine = HLA-B*1502 testing
required.
