areas of strength and weakness and remediate accordingly to prepare for
national certification exams.

SECTION A: PSYCHIATRIC-MENTAL HEALTH (PMHNP) –
QUESTIONS 1–30
Question 1
, A patient with major depressive disorder reports diminished interest in
all activities, fatigue, and poor concentration. Which neurotransmitter
systems are most implicated in these symptoms?
A. GABA and glutamate
B. Dopamine and serotonin
C. Acetylcholine and histamine
D. Endorphins and norepinephrine
B
RATIONALE: Major depressive symptoms stem largely from
dysregulation of serotonin and dopamine pathways, which influence
mood, energy, motivation, and concentration. Norepinephrine is also
often involved but dopamine-serotonin imbalance is the foundational
pairing. GABA and glutamate primarily mediate anxiety and cognition
rather than depressive affect.
Question 2
A 30-year-old client with panic disorder experiences episodes of
intense fear, palpitations, and shortness of breath. Which brain structure
is primarily involved in generating the "fight or flight" response?
A. Amygdala
B. Hippocampus
C. Thalamus
D. Prefrontal cortex
A
RATIONALE: The amygdala triggers the sympathetic nervous system
response characteristic of panic attacks. The hippocampus modulates
contextual memory of fear, the thalamus transmits sensory input, and the
prefrontal cortex regulates emotion but does not generate panic.
