AND CORRECT VERIFIED ANSWERS/ ALREADY
GRADED A+ (MOST RECENT!!)
Q1. A PMHNP is reviewing the mechanism of action of
selective serotonin reuptake inhibitors (SSRIs). Which
statement best describes their primary effect?
A. Blockade of norepinephrine reuptake in the synapse
B. Antagonism of dopamine D2 receptors
C. Inhibition of serotonin reuptake, increasing synaptic serotonin
D. Enhancement of GABA activity at the chloride channel
Correct Answer: C
Rationale: SSRIs block the serotonin transporter (SERT), increasing
serotonin availability in the synaptic cleft . This is the primary
mechanism responsible for their antidepressant and anxiolytic
effects. Options A (norepinephrine blockade) describes NRI
mechanisms, B describes antipsychotics, and D describes
benzodiazepines.

,Q2. A patient with major depressive disorder has a first-
degree relative with depression. This suggests:
A. No genetic contribution to depression
B. A possible heritable component to the disorder
C. An environmental cause only
D. Certainty that the patient will develop depression
Correct Answer: B
Rationale: First-degree relatives of individuals with major
depressive disorder have approximately a two- to threefold
increased risk of developing depression compared to the
general population . This suggests a significant heritable
component, though it does not guarantee development of the
disorder (gene-environment interactions matter).
Q3. The amygdala is responsible for:
A. Language production
B. Fear conditioning and emotional processing
C. Sleep-wake cycles
D. Motor coordination
Correct Answer: B
2
,Rationale: The amygdala is a key limbic system structure that
processes threat detection, emotional salience, and fear
conditioning . It is hyperactive in anxiety disorders and PTSD.
Language production is mediated by Broca's area (A); sleep-
wake cycles by the hypothalamus (C); motor coordination by the
cerebellum (D).
Q4. Long-term potentiation (LTP) is a cellular mechanism
underlying:
A. Neuronal cell death
B. Learning and memory
C. Neurotransmitter degradation
D. Myelination
Correct Answer: B
Rationale: Long-term potentiation (LTP) refers to the strengthening
of synaptic connections following repeated stimulation. It is a
fundamental cellular mechanism for learning, memory formation,
and neuroplasticity . LTP involves increased AMPA receptor
trafficking and NMDA receptor activation.
3
, Q5. Which brain structure is part of the limbic system?
A. Cerebellum
B. Basal ganglia
C. Hippocampus
D. Medulla oblongata
Correct Answer: C
Rationale: The hippocampus is a core limbic system structure
involved in memory formation, spatial navigation, and emotional
regulation . The amygdala and hypothalamus are other key
limbic structures. The cerebellum (A) coordinates movement, the
basal ganglia (B) are involved in motor control, and the medulla
(D) regulates autonomic functions.
Q6. A PMHNP prescribes a medication that blocks histamine
H1 receptors. Which side effect is most likely?
A. Insomnia
B. Weight loss
C. Sedation
D. Hypertension
Correct Answer: C
