PMHNP PRACTICE EXAM QUESTIONS
AND VERIFIED ANSWERS |GRADE A+|

1. Which dopaminergic pathway is primarily responsible for the positive symptoms of
schizophrenia, such as hallucinations and delusions?
A. Mesocortical pathway
B. Mesolimbic pathway
C. Nigrostriatal pathway
D. Tuberoinfundibular pathway
Answer: B
Conceptual Explanation: The mesolimbic pathway is associated with reward and
motivation; an overabundance of dopamine in this pathway leads to positive symptoms of
schizophrenia. The mesocortical pathway is associated with negative symptoms.
2. According to the Clozapine REMS program, what is the minimum Absolute Neutrophil
Count (ANC) required to initiate treatment in a non-BEN (Benign Ethnic Neutropenia) patient?
A. 1500/mm3
B. 1000/mm3
C. 500/mm3
,D. 2000/mm3
Answer: A
Conceptual Explanation: For the general population, the ANC must be greater than or
equal to 1500/mm3 to initiate Clozapine. For patients with documented BEN, the threshold
is 1000/mm3.
3. A 32-year-old patient taking Lithium for Bipolar I Disorder presents with coarse tremors,
ataxia, and confusion. What is the most likely Lithium serum level?
A. 2.1 mEq/L
B. 1.2 mEq/L
C. 1.4 mEq/L
D. 0.8 mEq/L
Answer: A
Conceptual Explanation: Serum levels above 1.5 mEq/L indicate toxicity. Coarse tremors,
ataxia, and confusion are signs of moderate to severe toxicity, typically seen when levels
exceed 2.0 mEq/L.
4. Which physical finding is most characteristic of Serotonin Syndrome compared to
Neuroleptic Malignant Syndrome (NMS)?
A. Lead-pipe muscle rigidity
B. Elevated Creatine Kinase (CK)
, C. Hyperreflexia and myoclonus
D. Autonomic instability
Answer: C
Conceptual Explanation: Serotonin syndrome is characterized by hyperreflexia and
myoclonus (especially in the lower extremities). NMS is distinguished by ‘lead-pipe’ rigidity
and significantly higher CK levels.
5. A 9-year-old boy is struggling in school and feels he cannot keep up with his peers.
According to Erikson, which stage of development is he in?
A. Initiative vs. Guilt
B. Autonomy vs. Shame and Doubt
C. Industry vs. Inferiority
D. Identity vs. Role Confusion
Answer: C
Conceptual Explanation: The stage of Industry vs. Inferiority occurs between ages 6 and
12, where children learn to be productive and compare themselves to peers.
6. A patient tells the PMHNP, ‘I am going to kill my ex-girlfriend when I leave here today.’
What is the PMHNP’s legal obligation based on the Tarasoff case?
A. Maintain patient confidentiality
B. Duty to warn the intended victim and notify law enforcement
