Multiple-Choice Questions
Question 1
A patient with major depressive disorder is prescribed sertraline. Which mechanism best explains
its therapeutic action?
A. Blocks dopamine receptors
B. Inhibits serotonin reuptake
,C. Blocks norepinephrine receptors
D. Enhances GABA activity
Correct Answer: B. Inhibits serotonin reuptake
Rationale:
Sertraline is a selective serotonin reuptake inhibitor (SSRI). By inhibiting serotonin reuptake into
the presynaptic neuron, it increases serotonin availability within the synaptic cleft, improving
depressive symptoms. Dopamine blockade is characteristic of antipsychotics, while GABA
enhancement occurs with benzodiazepines.
Question 2
Which antidepressant has the highest risk of hypertensive crisis when combined with tyramine-
rich foods?
A. Fluoxetine
B. Venlafaxine
C. Phenelzine
D. Bupropion
Correct Answer: C. Phenelzine
Rationale:
Phenelzine is a monoamine oxidase inhibitor (MAOI). Consuming tyramine-rich foods while
taking an MAOI may precipitate a hypertensive crisis because tyramine is no longer adequately
metabolized.
Question 3
Which neurotransmitter is primarily deficient in Parkinson disease?
A. Serotonin
B. Dopamine
C. Histamine
D. Acetylcholine
Correct Answer: B. Dopamine
,Rationale:
Parkinson disease results from degeneration of dopaminergic neurons in the substantia nigra,
leading to dopamine deficiency and characteristic motor symptoms.
Question 4
A patient taking lithium reports persistent vomiting and coarse tremors. What is the nurse
practitioner's priority action?
A. Continue medication
B. Increase the lithium dose
C. Evaluate for lithium toxicity
D. Recommend caffeine intake
Correct Answer: C. Evaluate for lithium toxicity
Rationale:
Vomiting, coarse tremor, confusion, and ataxia are concerning for lithium toxicity. Immediate
assessment and serum lithium measurement are warranted.
Question 5
Which laboratory value requires routine monitoring during lithium therapy?
A. Hemoglobin
B. Platelet count
C. Serum lithium level
D. Bilirubin
Correct Answer: C. Serum lithium level
Rationale:
Lithium has a narrow therapeutic index. Regular serum monitoring helps maintain therapeutic
efficacy while minimizing toxicity.
Question 6
Which medication is considered a first-line SSRI?
, A. Sertraline
B. Haloperidol
C. Lamotrigine
D. Buspirone
Correct Answer: A. Sertraline
Rationale:
Sertraline is a commonly prescribed SSRI and is considered first-line for major depressive
disorder and several anxiety disorders.
Question 7
Which adverse effect is most characteristic of clozapine?
A. Hyperthyroidism
B. Agranulocytosis
C. Renal failure
D. Cataracts
Correct Answer: B. Agranulocytosis
Rationale:
Clozapine carries a risk of severe neutropenia/agranulocytosis, requiring regular absolute
neutrophil count (ANC) monitoring.
Question 8
Which medication is FDA-approved for treatment-resistant schizophrenia?
A. Risperidone
B. Clozapine
C. Olanzapine
D. Quetiapine
Correct Answer: B. Clozapine
