Answers and Expert Explanation for Each Question

1. A 24-year-old female patient started on Fluoxetine (Prozac) two weeks ago and
presents with restlessness, muscle twitching, and diaphoresis. What is the most likely
diagnosis?
A. Anticholinergic toxicity
B. Neuroleptic Malignant Syndrome
C. Major Depressive Disorder relapse
D. Serotonin Syndrome
Correct Answer: D
Expert Explanation: Serotonin syndrome is a potentially life-threatening condition
caused by excessive serotonergic activity in the central nervous system. Clinical
features include mental status changes, autonomic hyperactivity, and
neuromuscular abnormalities such as clonus or hyperreflexia. The PMHNP must
immediately discontinue the offending agent and provide supportive care to manage
symptoms.
,2. Which neurotransmitter is primarily implicated in the reward system and is often
target of addiction research?
A. GABA
B. Acetylcholine
C. Serotonin
D. Dopamine
Correct Answer: D
Expert Explanation: Dopamine plays a central role in the brain’s reward system,
particularly within the mesolimbic pathway. It is released during pleasurable
activities and reinforces behaviors associated with survival or addiction.
Dysregulation in this system is a hallmark of substance use disorders and impulse
control issues.
3. A patient taking Clozapine (Clozaril) must have regular blood draws to monitor for
which life-threatening side effect?
A. Agranulocytosis
B. Hepatotoxicity
C. Renal failure
D. Thrombocytopenia
,Correct Answer: A
Expert Explanation: Agranulocytosis is a severe reduction in white blood cell count
that increases the risk of serious infection. Patients on Clozapine require strict
Absolute Neutrophil Count (ANC) monitoring per the REMS program. If the ANC falls
below specific thresholds, the medication must be discontinued immediately to
prevent sepsis.
4. Which brain structure is primarily responsible for the processing of fear and
emotional responses?
A. Hippocampus
B. Amygdala
C. Prefrontal Cortex
D. Thalamus
Correct Answer: B
Expert Explanation: The amygdala is a small, almond-shaped structure in the
temporal lobe that serves as the brain’s emotional processing center. it is
particularly involved in detecting threats and initiating the fear response through
the hypothalamic-pituitary-adrenal axis. Hyperactivity in the amygdala is frequently
observed in patients with anxiety and PTSD.
, 5. What is the therapeutic reference range for Lithium in the maintenance treatment
of Bipolar Disorder?
A. 0.2 to 0.5 mEq/L
B. 1.5 to 2.0 mEq/L
C. 0.6 to 1.2 mEq/L
D. 2.5 to 3.0 mEq/L
Correct Answer: C
Expert Explanation: The standard therapeutic range for lithium maintenance is
generally 0.6 to 1.2 mEq/L to ensure efficacy while minimizing toxicity. Levels
above 1.5 mEq/L are considered toxic and require immediate intervention to
prevent organ damage. Regular serum monitoring is essential due to the narrow
therapeutic index of this mood stabilizer.
6. A patient presents with a ‘lead-pipe’ muscle rigidity, high fever, and altered mental
status after starting Haloperidol. What should the PMHNP suspect?
A. Serotonin Syndrome
B. Acute Dystonia
C. Neuroleptic Malignant Syndrome (NMS)
D. Tardive Dyskinesia
