Q1 Question 1 of 75
2026/2027
A 24-year-old man is brought to the emergency department by his parents after stating that
neighbors have been planting listening devices in his apartment walls. He has become
increasingly withdrawn over the past three months and has stopped attending college
classes. He reports hearing a voice commenting on his actions throughout the day.
A. Excessive dopaminergic activity in the mesolimbic pathway is the primary neurochemical
mechanism underlying positive psychotic symptoms such as auditory hallucinations and
delusions.
B. Reduced dopamine transmission in the nigrostriatal pathway is responsible for the development
of positive symptoms in psychotic disorders.
C. Serotonin receptor hyperactivity in the prefrontal cortex is the predominant mechanism driving
psychotic symptom formation in this patient.
D. Deficient glutamate signaling at NMDA receptors is the sole neurobiological explanation for the
positive symptoms of psychosis observed here.
Correct Answer: A
Rationale:
The mesolimbic dopamine pathway, when hyperactive, is strongly associated with positive symptoms of schizophrenia
including hallucinations and delusions. Reduced dopamine in the nigrostriatal pathway, described in option B, explains
extrapyramidal side effects of antipsychotics rather than psychosis itself.

, Q2 Question 2 of 75
A 38-year-old woman presents to an outpatient psychiatric clinic with a six-month history of
persistent sadness, anhedonia, insomnia, and recurrent panic episodes. She describes an
overwhelming sense of dread that begins without warning and is accompanied by
palpitations, shortness of breath, and trembling. Her primary care physician started her on a
selective serotonin reuptake inhibitor two months ago with partial improvement.
A. Serotonin facilitates norepinephrine release exclusively in the locus coeruleus, which is the
primary mechanism of antidepressant efficacy.
B. Altered serotonergic neurotransmission in the raphe nuclei and cortical projection areas
contributes to both depressive and anxiety symptomatology.
C. Serotonin depletion in the basal ganglia is the singular cause of comorbid depression and panic
disorder in this patient.
D. Increased serotonin degradation by monoamine oxidase in the synaptic cleft is the primary
pathophysiology of treatment-resistant depression.
Correct Answer: B
Rationale:
Serotonin produced in the raphe nuclei projects widely throughout the cortex and limbic system, and dysregulation of these
pathways is implicated in both mood and anxiety disorders. Option A incorrectly attributes antidepressant efficacy solely to
norepinephrine facilitation, ignoring the direct serotonergic mechanisms.
Q3 Question 3 of 75
A 28-year-old man is evaluated for chronic difficulty sustaining attention at work, frequent
careless errors, and restlessness that has persisted since childhood. He reports that his
father and brother were both diagnosed with a similar condition. After comprehensive testing,
he is diagnosed with attention-deficit/hyperactivity disorder, combined presentation.
A. Norepinephrine acts exclusively on alpha-2 adrenergic receptors in the periphery to produce its
therapeutic effects in attention-deficit/hyperactivity disorder.
B. Dopamine depletion in the motor cortex is the primary neurochemical abnormality responsible
for inattentive symptoms in this patient.
C. Norepinephrine and dopamine regulation in the prefrontal cortex is critical for sustained
attention, working memory, and impulse control.
D. Serotonin reuptake inhibition in the thalamus is the main pharmacological target for managing
attention-deficit/hyperactivity disorder symptoms.
Correct Answer: C
Rationale:
Both norepinephrine and dopamine in the prefrontal cortex are essential for executive functioning, and medications like
atomoxetine target norepinephrine reuptake in this region. Option A incorrectly limits norepinephrine action to peripheral
alpha-2 receptors, ignoring central prefrontal cortex mechanisms that are central to ADHD.

, Q4 Question 4 of 75
A 45-year-old woman arrives at the psychiatric urgent care clinic in severe distress, reporting
intense chest tightness, sweating, and a feeling of impending doom that began abruptly two
hours ago. She has experienced four similar episodes in the past month and now avoids
leaving her home for fear of having another attack in public. She has no significant medical
history.
A. Benzodiazepines enhance glutamate release at NMDA receptors, producing rapid anxiolytic
effects by increasing excitatory neurotransmission.
B. Benzodiazepines act as direct GABA receptor agonists, mimicking the structure of
gamma-aminobutyric acid at the synaptic cleft.
C. Benzodiazepines block sodium channel conduction in neurons, reducing neuronal excitability
and producing rapid sedation.
D. Benzodiazepines are positive allosteric modulators that enhance GABA-A receptor activity by
increasing the frequency of chloride channel opening.
Correct Answer: D
Rationale:
Benzodiazepines bind to a specific site on the GABA-A receptor complex and increase the frequency of chloride channel
opening when GABA is present, producing anxiolysis. Option B is incorrect because benzodiazepines are not direct
agonists; they require endogenous GABA and only modulate receptor activity allosterically.
Q5 Question 5 of 75
A 52-year-old man with treatment-resistant major depressive disorder has failed trials of four
different antidepressant medications over three years. His psychiatrist discusses a novel
treatment approach targeting the glutamatergic system. The patient has no history of
substance use disorder or psychotic symptoms.
A. Ketamine produces rapid antidepressant effects by blocking NMDA receptors, which leads to
increased AMPA receptor activation and enhanced synaptic plasticity.
B. NMDA receptor activation directly increases serotonin synthesis in the dorsal raphe nucleus,
making it the primary target for conventional antidepressant therapy.
C. Glutamate hypofunction exclusively in the cerebellum is the established cause of
treatment-resistant depression in this case.
D. Reducing glutamate levels throughout the brain is the principal mechanism by which ketamine
achieves its rapid antidepressant effect.
Correct Answer: A
Rationale:
Ketamine acts as an NMDA receptor antagonist, and this blockade leads to a surge of glutamate that activates AMPA
receptors, triggering downstream signaling that promotes synaptic plasticity and rapid mood improvement. Option D is
incorrect because ketamine does not reduce glutamate levels; it paradoxically increases glutamate release through NMDA
receptor blockade.
