mechanism of action of typical antipsychotics?
- A) Norepinephrine

D2 receptors, which reduces psychotic symptoms.


2. SSRIs (Selective Serotonin Reuptake Inhibitors) primarily exert
their effects by:
- A) Inhibiting serotonin synthesis
- B) Blocking serotonin receptors
- C) Preventing the reuptake of serotonin
- D) Increasing norepinephrine levels
Answer: C) Preventing the reuptake of serotonin
Rationale: SSRIs block the reuptake of serotonin at the
synaptic cleft, leading to increased serotonin levels.

administration of an SSRI and a monoamine oxidase inhibitor
(MAOI)?
- A) Increased sedation
- B) Serotonin syndrome
- C) Decreased efficacy of the SSRI
