75 Questions with answers and detailled Rationale
1. A patient with schizophrenia exhibits positive symptoms (hallucinations, delusions).
Which neurotransmitter pathway is primarily implicated in the pathophysiology of these
positive symptoms?
A. Decreased norepinephrine in the locus coeruleus
B. Hyperdopaminergia in the mesolimbic pathway [CORRECT]
C. Hypodopaminergia in the mesocortical pathway
D. Increased serotonin in the raphe nuclei
Correct Answer: B
Rationale: Correct because the dopamine hypothesis of schizophrenia posits that
excess dopamine transmission in the mesolimbic pathway is responsible for positive
symptoms. This matches the current neurobiological understanding of psychosis.
Q2: Which GABA receptor subtype is primarily responsible for the anxiolytic effects of
benzodiazepines?
A. GABA-A alpha-1 subunit
B. GABA-A alpha-2 subunit [CORRECT]
C. GABA-B receptor
D. GABA-C receptor
,Correct Answer: B
Rationale: Correct because the alpha-2 subunit of the GABA-A receptor is primarily
associated with anxiolysis, while the alpha-1 subunit mediates sedation. This matches
the receptor pharmacology of benzodiazepines.
Q3: A patient is prescribed a medication that blocks the serotonin transporter (SERT).
What is the immediate effect on synaptic serotonin levels?
A. Decreased serotonin due to autoreceptor activation
B. Increased serotonin in the synaptic cleft [CORRECT]
C. Decreased serotonin due to increased metabolism by MAO
D. No change in serotonin levels
Correct Answer: B
Rationale: Correct because blocking the serotonin transporter prevents reuptake,
leading to accumulation of serotonin in the synaptic cleft. This matches the mechanism
of action of SSRIs.
Q4: Which receptor antagonism is most associated with the metabolic side effects
(weight gain, dyslipidemia) of second-generation antipsychotics?
A. D2 receptor antagonism
B. 5-HT2C receptor antagonism [CORRECT]
C. H1 receptor agonism
D. M1 receptor antagonism
Correct Answer: B
Rationale: Correct because blockade of 5-HT2C receptors increases appetite and
disrupts glucose homeostasis, contributing to metabolic syndrome. This matches the
pharmacologic profile of drugs like olanzapine and clozapine.
, Q5: The "first episode" of schizophrenia is often preceded by a prodromal phase
characterized by "negative symptoms." Which neurochemical change is associated with
negative symptoms and cognitive deficits?
A. Hyperdopaminergia in mesolimbic pathway
B. Hypodopaminergia in mesocortical pathway [CORRECT]
C. Hyperglutamatergia in hippocampus
D. Hypocholinergic activity in basal forebrain
Correct Answer: B
Rationale: Correct because reduced dopamine transmission in the mesocortical
pathway (projecting to the prefrontal cortex) is linked to negative symptoms and
cognitive impairment. This matches the dopamine hypothesis.
Q6: Which neurotransmitter is the primary inhibitory neurotransmitter in the CNS,
targeted by alcohol and benzodiazepines?
A. Glutamate
B. GABA (Gamma-aminobutyric acid) [CORRECT]
C. Dopamine
D. Acetylcholine
Correct Answer: B
Rationale: Correct because GABA is the main inhibitory neurotransmitter, and
positive allosteric modulators of GABA-A receptors produce sedation and anxiolysis.
This matches basic neuropharmacology.
Q7: Ketamine produces rapid antidepressant effects primarily through which
mechanism?
A. Blockade of serotonin reuptake
B. Antagonism of NMDA glutamate receptors [CORRECT]
C. Agonism of mu-opioid receptors
D. Blockade of dopamine D2 receptors
Correct Answer: B
