PMHNP ADVANCED PRACTICE EXAM
QUESTIONS AND VERIFIED ANSWERS
|GRADE A+| JUST RELEASED
1. Excessive dopamine in which pathway is most associated with 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 involves the projection of dopamine
from the ventral tegmental area to the nucleus accumbens. Hyperactivity here is linked to
positive symptoms.
2. Blockade of dopamine in which pathway is responsible for Extrapyramidal Symptoms
(EPS)?
A. Mesocortical pathway
,B. Mesolimbic pathway
C. Tuberoinfundibular pathway
D. Nigrostriatal pathway
Answer: D
Conceptual Explanation: The nigrostriatal pathway controls motor function.
Antipsychotic blockade here leads to motor side effects like dystonia and parkinsonism.
3. A deficit of dopamine in the mesocortical pathway is primarily associated with which
clinical manifestation?
A. Auditory hallucinations
B. Negative symptoms and cognitive impairment
C. Hyperprolactinemia
D. Tardive dyskinesia
Answer: B
Conceptual Explanation: Low dopamine levels in the mesocortical pathway are thought to
contribute to the cognitive deficits and negative symptoms of schizophrenia.
4. Which pathway is responsible for the side effect of galactorrhea when dopamine is blocked
by antipsychotics?
A. Tuberoinfundibular
B. Mesocortical
, C. Nigrostriatal
D. Mesolimbic
Answer: A
Conceptual Explanation: Dopamine inhibits prolactin in the tuberoinfundibular pathway.
Blocking it causes prolactin levels to rise, leading to breast milk production and menstrual
changes.
5. To initiate Clozapine therapy, what is the minimum Absolute Neutrophil Count (ANC)
required?
A. 1500/mm3
B. 1000/mm3
C. 500/mm3
D. 2000/mm3
Answer: A
Conceptual Explanation: The FDA Clozapine REMS program requires an ANC of at least
1500/mm3 for the general population before starting treatment to monitor for
agranulocytosis.
6. Which medication is most likely to cause a significant increase in Lithium levels, potentially
leading to toxicity?
A. Pseudoephedrine
