Questions & Verified Answers
1. Which dopamine pathway is primarily responsible for the positive symptoms of
schizophrenia, such as hallucinations and delusions?
A. Mesocortical pathway
B. Tuberoinfundibular pathway
C. Nigrostriatal pathway
D. Mesolimbic pathway
Answer: D
Rationale: The mesolimbic pathway involves the projection of dopamine from the ventral tegmental area to the
nucleus accumbens; overactivity here is linked to positive symptoms. Applying this knowledge in clinical
settings supports safe, evidence-based practice and improves patient outcomes.
2. Which antidepressant is most likely to cause a hypertensive crisis if taken with foods high in
tyramine?
A. Fluoxetine
B. Bupropion
C. Phenelzine
D. Venlafaxine
Answer: C
Rationale: Phenelzine is an MAOI; inhibiting monoamine oxidase prevents the breakdown of tyramine, leading
to dangerous increases in blood pressure. 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. What is the primary mechanism of action of typical (first-generation) antipsychotics?
A. Serotonin 2A antagonism
B. Norepinephrine reuptake inhibition
C. Dopamine D2 receptor antagonism
D. GABA modulation
Answer: C
Rationale: First-generation antipsychotics primarily block D2 receptors in the brain to reduce psychotic
symptoms. 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. Which mood stabilizer is associated with a rare but life-threatening skin reaction known as
Stevens-Johnson Syndrome (SJS)?
A. Lithium
B. Lamotrigine
C. Valproic Acid
D. Carbamazepine
Answer: B
Rationale: Lamotrigine carries a boxed warning for SJS; slow titration is required to mitigate this risk.
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.
5. What is the therapeutic range for Lithium in the maintenance phase of treating Bipolar
Disorder?
A. 0.6 to 1.2 mEq/L
B. 1.5 to 2.0 mEq/L
C. 0.2 to 0.5 mEq/L
D. 2.5 to 3.5 mEq/L
Answer: A
Rationale: The standard maintenance therapeutic window for lithium is 0.6 to 1.2 mEq/L; levels above 1.5
indicate toxicity. 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.
6. Which neurotransmitter is considered the primary inhibitory neurotransmitter in the central
nervous system?
A. Glutamate
B. Norepinephrine
C. GABA
D. Acetylcholine
Answer: C
Rationale: GABA (gamma-aminobutyric acid) is the main inhibitory neurotransmitter, while glutamate is the
main excitatory one. 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.
