Questions & Verified Answers
1. Which dopamine pathway is primarily associated with the positive symptoms of
schizophrenia, such as hallucinations and delusions?
A. Mesolimbic pathway
B. Mesocortical pathway
C. Nigrostriatal pathway
D. Tuberoinfundibular pathway
Answer: A
Rationale: The mesolimbic pathway is associated with reward and pleasure, and overactivity in this pathway is
linked to the positive symptoms of schizophrenia. 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.
2. A patient taking a Second Generation Antipsychotic (SGA) exhibits significant weight gain
and elevated glucose levels. Which receptor is most likely responsible for these metabolic side
effects?
A. exhibits significant weight gain and elevated glucose levels. Which receptor is most likely responsible
for these metabolic side effects?
B. H1 histamine and 5-HT2C receptors
C. 5-HT2A receptor
D. Alpha-1 adrenergic receptor
Answer: B
Rationale: Antagonism of H1 histamine and 5-HT2C receptors is strongly associated with weight gain and
increased metabolic risk in patients taking SGAs. 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.
3. Which cytochrome P450 enzyme is significantly induced by cigarette smoking, potentially
lowering the serum levels of drugs like clozapine and olanzapine?
A. CYP1A2
B. CYP3A4
C. CYP2D6
D. CYP2C19
Answer: A
Rationale: Polycyclic aromatic hydrocarbons in cigarette smoke induce CYP1A2, which increases the
metabolism of drugs like clozapine, requiring dose adjustments if a patient starts or stops smoking. Applying
this knowledge in clinical settings supports safe, evidence-based practice and improves patient outcomes.

4. A patient prescribed an SSRI reports sudden onset of confusion, agitation, diaphoresis, and
muscle rigidity after taking an over-the-counter cough medicine. What is the most likely
diagnosis?
A. Neuroleptic Malignant Syndrome
B. Hypertensive Crisis
C. Anticholinergic Toxicity
D. Serotonin Syndrome
Answer: D
Rationale: Serotonin Syndrome occurs when there is an excess of serotonin, often due to drug interactions
(e.g., SSRI and dextromethorphan), presenting with autonomic instability and neuromuscular hyperactivity.
Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide accurate
patient education.
5. What is the primary mechanism of action of Buspirone in the treatment of Generalized
Anxiety Disorder?
A. GABA-A positive allosteric modulator
B. 5-HT1A partial agonist
C. Norepinephrine reuptake inhibitor
D. D2 receptor antagonist
Answer: B
Rationale: Buspirone acts as a partial agonist at the 5-HT1A receptor, which helps alleviate anxiety symptoms
without the sedation associated with benzodiazepines. This is an important clinical concept because selecting
the correct answer (B) 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.
6. Which of the following antidepressants is contraindicated in patients with a history of seizure
disorders or eating disorders?
A. Bupropion
B. Sertraline
C. Fluoxetine
D. Venlafaxine
Answer: A
Rationale: Bupropion lowers the seizure threshold and is specifically contraindicated in patients with epilepsy
or those with active or history of bulimia or anorexia nervosa. Exam questions often test the ability to distinguish
this concept from closely related distractors, making a clear rationale essential for mastery.
