QUESTIONS AND ANSWERS
1. A 28-year-old female patient on clozapine (Clozaril) has an Absolute Neutrophil Count
(ANC) of 950/mm³. What is the required clinical action per the Clozapine REMS program?
A. Continue the current dose and recheck ANC in one week.
B. Add lithium to stimulate white blood cell production immediately.
C. Increase the dose to treat potential subtherapeutic levels.
D. Interrupt treatment and monitor ANC daily until it returns to ≥1000/mm³.
Answer: D
Conceptual Explanation: According to the Clozapine REMS program, an ANC between
500-999/mm³ (mild-to-moderate neutropenia) requires treatment interruption and daily
monitoring until the ANC stabilizes or rises.
2. Which dopaminergic pathway is associated with the development of extrapyramidal
symptoms (EPS) and tardive dyskinesia when blocked by antipsychotics?
A. Mesolimbic pathway
B. Mesocortical pathway
,C. Tuberoinfundibular pathway
D. Nigrostriatal pathway
Answer: D
Conceptual Explanation: Blockade of dopamine in the nigrostriatal pathway leads to
motor side effects, including EPS and tardive dyskinesia.
3. What is the therapeutic reference range for serum lithium levels in the maintenance
treatment of Bipolar Disorder?
A. 0.6 to 1.2 mEq/L
B. 0.1 to 0.5 mEq/L
C. 1.5 to 2.0 mEq/L
D. 2.0 to 3.0 mEq/L
Answer: A
Conceptual Explanation: The standard therapeutic range for lithium is 0.6 to 1.2 mEq/L.
Levels above 1.5 mEq/L are typically considered toxic.
4. A patient presenting with hyperreflexia, myoclonus, and diaphoresis after starting an SSRI
is most likely experiencing:
A. Neuroleptic Malignant Syndrome (NMS)
B. Serotonin Syndrome
C. Anticholinergic Toxicity
, D. Agranulocytosis
Answer: B
Conceptual Explanation: Serotonin syndrome is characterized by neuromuscular
excitability like hyperreflexia and myoclonus, whereas NMS is characterized by ‘lead-pipe’
rigidity and hyporeflexia.
5. Which legal principle, derived from a California Supreme Court case, establishes the ‘duty
to warn’ potential victims of a patient’s threats?
A. O’Connor v. Donaldson
B. Tarasoff v. Regents of the University of California
C. Durham v. United States
D. Rennie v. Klein
Answer: B
Conceptual Explanation: The Tarasoff rule mandates that mental health professionals
have a duty to warn and protect individuals who are being threatened with bodily harm by
a patient.
6. Which brain region is primarily responsible for executive functions, impulse control, and
emotional regulation?
A. Hippocampus
B. Thalamus
