CORRECT
Q1 — SSRI mechanism of action
Which of the following best describes the mechanism of action of SSRIs
such as fluoxetine and sertraline?
A. Block dopamine reuptake at the presynaptic neuron
B. Inhibit serotonin reuptake at the presynaptic transporter
C. Block norepinephrine release from vesicles
D. Increase GABA receptor activity
Answer: B
Rationale: SSRIs selectively block serotonin reuptake, increasing serotonin
availability in the synapse.

monitoring is mandatory.
Q6 — Benzodiazepine mechanism of action
A. Block NMDA receptors
B. Increase frequency of chloride channel opening via GABA-A receptor
C. Inhibit serotonin reuptake
D. Block norepinephrine reuptake
Answer: B
Rationale: Benzodiazepines are GABA-A receptor allosteric modulators,
enhancing inhibitory neurotransmission.
Q7 — First-line treatment for ADHD in school-aged children
A. Antipsychotics
B. SSRIs
C. Stimulants
D. Alpha-2 agonists
Answer: C
