Question 1

Which class of antidepressants works primarily by inhibiting the reuptake of serotonin into presynaptic neurons?

Accepted Answer

Selective serotonin reuptake inhibitors (SSRIs)

Answer

SSRIs selectively block the reabsorption of serotonin into presynaptic neurons, increasing serotonin availability in the synapse and producing antidepressant effects.

Question 2

Which mood stabilizer requires regular serum level monitoring due to its narrow therapeutic window?

Accepted Answer

Lithium

Answer

Lithium has a narrow therapeutic window (0.6–1.2 mEq/L) and requires regular blood level monitoring to avoid toxicity while maintaining efficacy.

Question 3

A client taking an MAOI should avoid which dietary component to prevent hypertensive crisis?

Accepted Answer

Tyramine

Answer

MAOIs inhibit the enzyme that breaks down tyramine; consuming tyramine-rich foods such as aged cheeses and cured meats can trigger a dangerous hypertensive crisis.

Question 4

What is the primary mechanism of action of benzodiazepines?

Accepted Answer

Enhancing the effect of GABA at the GABA-A receptor

Answer

Benzodiazepines bind to the GABA-A receptor and potentiate the inhibitory effects of GABA, producing anxiolytic, sedative, and muscle-relaxant effects.

Question 5

Which atypical antipsychotic is associated with the highest risk of agranulocytosis and requires enrollment in a mandatory monitoring program?

Accepted Answer

Clozapine

Answer

Clozapine carries a significant risk of agranulocytosis (a dangerous drop in white blood cells), requiring mandatory regular blood count monitoring through the FDA REMS program.
