SECTION 1: PSYCHOPHARMACOLOGY (Q1–Q40)
Q1. A patient with schizophrenia has been on haloperidol for 6 months and now
presents with involuntary tongue movements, lip smacking, and facial grimacing. What
,is the most likely diagnosis?
A. Acute dystonia
B. Tardive dyskinesia ✅
C. Akathisia
D. Parkinsonism
Rationale: Tardive dyskinesia is a late-onset extrapyramidal side effect (after
months/years) characterized by involuntary repetitive movements, especially of the
tongue, lips, and face. Acute dystonia occurs early (hours–days), akathisia is restlessness,
and parkinsonism includes tremor/rigidity.
Q2. Which medication is first-line for a patient with bipolar I disorder in an acute manic
episode?
A. Fluoxetine
B. Lithium ✅
C. Sertraline
D. Buspirone
Rationale: Lithium is a first-line mood stabilizer for acute mania and maintenance in
bipolar I disorder. SSRIs like fluoxetine and sertraline can precipitate mania. Buspirone is
for anxiety.
Q3. A patient on clozapine develops fever, tachycardia, muscle rigidity, and altered
mental status. What is the priority nursing action?
A. Continue clozapine and monitor
B. Stop clozapine immediately and notify the provider ✅
C. Administer benztropine
D. Increase clozapine dose
Rationale: These are signs of neuroleptic malignant syndrome (NMS), a life-threatening
emergency. Clozapine must be stopped immediately, and emergency treatment
initiated.
,Q4. Which laboratory test is mandatory before starting carbamazepine?
A. CBC and liver function tests ✅
B. Thyroid function tests
C. Serum lithium level
D. Urine toxicology
Rationale: Carbamazepine can cause aplastic anemia, agranulocytosis, and
hepatotoxicity. Baseline CBC and LFTs are required, with periodic monitoring.
Q5. A patient with major depressive disorder has not responded to two adequate trials
of SSRIs. What is the best next step?
A. Continue the same SSRI at a higher dose
B. Switch to a different class such as an SNRI or augment with bupropion ✅
C. Add a benzodiazepine
D. Start a typical antipsychotic
Rationale: After two failed SSRI trials, switching to another class (SNRI, bupropion,
mirtazapine) or augmentation is recommended. Benzodiazepines are not for depression.
Typical antipsychotics are not first-line.
Q6. Which medication requires dietary tyramine restriction?
A. Fluoxetine
B. Phenelzine ✅
C. Sertraline
D. Escitalopram
Rationale: Phenelzine is an MAOI. Tyramine-rich foods can cause a hypertensive crisis.
SSRIs do not require tyramine restriction.
Q7. A patient on lithium reports increased urination and thirst. Which adverse effect is
most likely?
A. Nephrogenic diabetes insipidus ✅
B. Syndrome of inappropriate antidiuretic hormone (SIADH)
, C. Hyperkalemia
D. Hypoglycemia
Rationale: Lithium can cause nephrogenic diabetes insipidus, leading to polyuria and
polydipsia. SIADH causes fluid retention and hyponatremia.
Q8. Which antipsychotic has the highest risk of agranulocytosis?
A. Risperidone
B. Olanzapine
C. Clozapine ✅
D. Quetiapine
Rationale: Clozapine carries a black box warning for severe
neutropenia/agranulocytosis. Regular ANC monitoring is required.
Q9. A patient with generalized anxiety disorder is prescribed buspirone. What should
the PMHNP teach?
A. It works immediately
B. It takes 2–4 weeks for full effect ✅
C. It is habit-forming
D. It should be taken with grapefruit juice
Rationale: Buspirone has a delayed onset of 2–4 weeks. It is not habit-forming and does
not require grapefruit avoidance (unlike some benzodiazepines metabolized by
CYP3A4).
Q10. Which medication is FDA-approved for treatment-resistant schizophrenia?
A. Haloperidol
B. Clozapine ✅
C. Chlorpromazine
D. Fluphenazine
