NRNP 6635 COMPREHENSIVE PMHNP
EXAM PREP QUESTIONS AND
ANSWERS
1. Which dopaminergic pathway is primarily associated with the development of positive
symptoms in schizophrenia, such as hallucinations and delusions?
A. Mesolimbic pathway
B. Nigrostriatal pathway
C. Mesocortical pathway
D. Tuberoinfundibular pathway
Answer: A
Conceptual Explanation: Overactivity in the mesolimbic pathway is linked to positive
symptoms, whereas the mesocortical pathway is linked to negative and cognitive
symptoms.
2. A patient taking Clozapine presents with a sudden fever, sore throat, and lethargy. What is
the most critical immediate diagnostic step?
A. Chest X-ray to rule out pneumonia
,B. Liver function tests
C. Electrocardiogram (ECG) for QTc prolongation
D. Complete Blood Count (CBC) with differential
Answer: D
Conceptual Explanation: Clozapine carries a black box warning for agranulocytosis; fever
and sore throat are clinical signs of neutropenia requiring immediate ANC verification.
3. Which anatomical structure is responsible for the regulation of the circadian rhythm and
acts as the body’s internal clock?
A. Suprachiasmatic nucleus (SCN)
B. Hippocampus
C. Amygdala
D. Thalamus
Answer: A
Conceptual Explanation: The SCN, located in the hypothalamus, regulates melatonin
production and the sleep-wake cycle.
4. What is the primary mechanism of action of Benzodiazepines in the treatment of anxiety?
A. Positive allosteric modulation of GABA-A receptors
B. Reuptake inhibition of Serotonin
, C. Antagonism of NMDA receptors
D. Partial agonism at 5-HT1A receptors
Answer: A
Conceptual Explanation: Benzodiazepines increase the frequency of chloride channel
opening by enhancing the effects of GABA at the GABA-A receptor.
5. According to DSM-5 criteria, what is the minimum duration of symptoms required to
diagnose Generalized Anxiety Disorder (GAD)?
A. 2 weeks
B. 1 month
C. 6 months
D. 3 months
Answer: C
Conceptual Explanation: DSM-5 requires excessive anxiety and worry occurring more
days than not for at least 6 months for a GAD diagnosis.
6. Which of the following findings is most characteristic of Neuroleptic Malignant Syndrome
(NMS) compared to Serotonin Syndrome?
A. Lead-pipe muscle rigidity
B. Hyperthermia
C. Hyperreflexia and myoclonus
