Questions & Verified Answers
1. Which neurotransmitter is primarily responsible for the ‘reward’ pathway in the brain?
A. Dopamine
B. Serotonin
C. GABA
D. Glutamate
Answer: A
Rationale: Dopamine is the primary neurotransmitter associated with the reward system, particularly in the
mesolimbic pathway. Applying this knowledge in clinical settings supports safe, evidence-based practice and
improves patient outcomes. This is an important clinical concept because selecting the correct answer (A)
requires understanding both the pathophysiology and the practical nursing implications.
2. A patient on Clozapine must have regular monitoring of which laboratory value to screen for
agranulocytosis?
A. Serum Creatinine
B. Liver Function Tests (LFTs)
C. Absolute Neutrophil Count (ANC)
D. Hemoglobin A1c
Answer: C
Rationale: Clozapine carries a risk of life-threatening agranulocytosis, necessitating strict ANC monitoring via
the REMS program. Applying this knowledge in clinical settings supports safe, evidence-based practice and
improves patient outcomes. This is an important clinical concept because selecting the correct answer (C)
requires understanding both the pathophysiology and the practical nursing implications.
3. Which antidepressant is most likely to cause a hypertensive crisis if taken with tyramine- rich
foods?
A. Sertraline
B. Venlafaxine
C. Bupropion
D. Phenelzine
Answer: D
Rationale: Phenelzine is an MAOI; inhibiting MAO prevents the breakdown of tyramine, leading to excessive
norepinephrine release and hypertensive crisis. Exam questions often test the ability to distinguish this concept
from closely related distractors, making a clear rationale essential for mastery. Applying this knowledge in
clinical settings supports safe, evidence-based practice and improves patient outcomes.

4. What is the primary mechanism of action of typical (first-generation) antipsychotics?
A. Dopamine D2 antagonism
B. Dopamine D2 agonism
C. Norepinephrine reuptake inhibition
D. Serotonin 5-HT2A antagonism
Answer: A
Rationale: First-generation antipsychotics work primarily by blocking D2 receptors in the mesolimbic pathway
to reduce positive symptoms of schizophrenia. This is an important clinical concept because selecting the
correct answer (A) requires understanding both the pathophysiology and the practical nursing implications.
Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide accurate
patient education.
5. Which mood stabilizer is associated with a risk of Stevens-Johnson Syndrome, especially if
titrated too quickly?
A. Lamotrigine
B. Lithium
C. Valproate
D. Topiramate
Answer: A
Rationale: Lamotrigine requires a slow titration schedule to minimize the risk of a severe, potentially fatal rash
known as Stevens-Johnson Syndrome. Recognizing this principle allows the nurse to prioritize care, anticipate
complications, and provide accurate patient education. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery.
6. A patient experiencing muscle rigidity, high fever, and autonomic instability while on
Haloperidol is likely suffering from:
A. Serotonin Syndrome
B. Tardive Dyskinesia
C. Neuroleptic Malignant Syndrome (NMS)
D. Akathisia
Answer: C
Rationale: NMS is a medical emergency characterized by ‘lead-pipe’ rigidity, hyperthermia, and autonomic
dysfunction caused by D2 blockade. Recognizing this principle allows the nurse to prioritize care, anticipate
complications, and provide accurate patient education. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery.
