1. A patient taking Clozapine presents for a weekly follow-up. The Absolute Neutrophil Count
(ANC) is 1,200/mm³. Which of the following is the most appropriate action according to FDA
guidelines?
A. Interrupt treatment, notify the Clozapine REMS, and monitor ANC daily until it returns to
>1,500/mm³.
B. Increase the dose to manage symptoms while monitoring lab work.
C. Continue the current dose and recheck ANC in one week.
D. Discontinue Clozapine permanently regardless of future ANC levels.
Answer: A
Conceptual Explanation: For General Population patients, an ANC between 1,000–
1,499/mm³ (mild neutropenia) requires treatment interruption and daily monitoring until
the ANC is ≥1,500/mm³.
2. Which dopaminergic pathway is primarily associated with the development of
extrapyramidal symptoms (EPS) and tardive dyskinesia?
A. Nigrostriatal pathway
,B. Mesolimbic pathway
C. Mesocortical pathway
D. Tuberoinfundibular pathway
Answer: A
Conceptual Explanation: The nigrostriatal pathway controls motor function; D2 receptor
blockade in this pathway leads to EPS and tardive dyskinesia.
3. A 45-year-old male with Bipolar I Disorder presents with tremors, ataxia, and confusion.
His Lithium level is 2.2 mEq/L. What is the most likely diagnosis?
A. Therapeutic Lithium levels
B. Serotonin Syndrome
C. Neuroleptic Malignant Syndrome
D. Lithium toxicity
Answer: D
Conceptual Explanation: Lithium toxicity usually occurs at levels >1.5 mEq/L; symptoms
include coarse tremors, ataxia, diarrhea, and confusion.
4. According to Erik Erikson, which psychosocial stage is a 25-year-old individual navigating?
A. Identity vs. Role Confusion
B. Generativity vs. Stagnation
, C. Intimacy vs. Isolation
D. Autonomy vs. Shame and Doubt
Answer: C
Conceptual Explanation: Young adulthood (ages 18–40) focuses on developing intimate
relationships, characterized by the Intimacy vs. Isolation stage.
5. A patient is prescribed Fluoxetine 20mg daily. Which Cytochrome P450 enzyme is
significantly inhibited by this medication, potentially increasing the levels of other drugs?
A. CYP2D6
B. CYP3A4
C. CYP1A2
D. CYP2C19
Answer: A
Conceptual Explanation: Fluoxetine and Paroxetine are potent inhibitors of the CYP2D6
enzyme.
6. Which brain region is primarily responsible for executive functions, such as planning,
working memory, and impulse control?
A. Amygdala
B. Hippocampus
C. Prefrontal Cortex
