PMHNP FINAL EXAM
COMPREHENSIVE PRACTICE
QUESTIONS AND VERIFIED ANSWERS
|GRADE A+| JUST RELEASED
1. A patient taking Clozapine presents with a sudden onset of high fever, muscle rigidity, and
tachycardia. What is the most likely diagnosis considering both the medication and the
presentation?
A. Serotonin Syndrome
B. Neuroleptic Malignant Syndrome (NMS)
C. Agranulocytosis
D. Anticholinergic Toxicity
Answer: B
Conceptual Explanation: While agranulocytosis is a major concern with Clozapine due to
low ANC, the presentation of fever, ‘lead-pipe’ rigidity, and autonomic instability points
toward NMS, a life-threatening reaction to antipsychotics.
2. Which dopamine pathway is responsible for the negative symptoms of Schizophrenia, such
as flat affect and alogia?
A. Mesolimbic pathway
,B. Nigrostriatal pathway
C. Mesocortical pathway
D. Tuberoinfundibular pathway
Answer: C
Conceptual Explanation: Hypofunction of the mesocortical pathway is associated with
negative symptoms and cognitive impairment, whereas hyperfunction of the mesolimbic
pathway causes positive symptoms.
3. A 45-year-old male smoker is stable on Olanzapine 20mg daily. He decides to quit smoking.
What should the PMHNP anticipate regarding his medication level?
A. The Olanzapine level will decrease.
B. The Olanzapine level will increase.
C. Smoking cessation has no effect on Olanzapine.
D. Nicotine patches will maintain the same enzyme induction.
B. The Olanzapine level will increase.
Answer: B
Conceptual Explanation: Tobacco smoke (not nicotine) induces the CYP1A2 enzyme.
When a patient stops smoking, the induction ceases, leading to higher serum levels of drugs
metabolized by 1A2, such as Olanzapine and Clozapine.
, 4. Which part of the brain is primarily involved in the regulation of fear, anxiety, and
emotional memory?
A. Hippocampus
B. Amydgala
C. Prefrontal Cortex
D. Basal Ganglia
Answer: B
Conceptual Explanation: The amygdala is the core structure for processing fear and
emotional responses. The hippocampus is more involved in memory consolidation.
5. A patient with Bipolar I disorder is prescribed Lithium. Which of the following lab findings
would most likely increase the risk of Lithium toxicity?
A. Hypernatremia
B. Hypokalemia
C. Hyponatremia
D. Hypercalcemia
Answer: C
Conceptual Explanation: Lithium is a salt. When sodium levels are low (hyponatremia),
the kidneys reabsorb more Lithium to compensate, leading to toxic serum levels.
