1. Norepinephrine is primarily synthesized in which brain structure?
A. Raphe nuclei
B. Locus coeruleus
C. Substantia nigra
D. Nucleus accumbens
Answer: B. Locus coeruleus
Rationale: The locus coeruleus, located in the pons, is the principal source of norepinephrine in
the CNS. Norepinephrine contributes to arousal, attention, vigilance, and the stress response. The
raphe nuclei are primarily associated with serotonin, while the substantia nigra is an important
source of dopamine.
2. Which neurotransmitter is primarily produced by neurons in the raphe nuclei?
A. Dopamine
B. GABA
C. Serotonin
D. Norepinephrine
Answer: C. Serotonin
Rationale: The raphe nuclei are the major serotonergic nuclei of the brainstem. Serotonin is
involved in mood, anxiety, sleep, appetite, and several other functions. This is a high-yield
neurobiology association for PMHNP preparation.
3. A patient taking lithium develops polyuria and polydipsia. Which condition should the
PMHNP suspect?
A. SIADH
B. Nephrogenic diabetes insipidus
C. Acute renal failure
D. Primary polydipsia
Answer: B. Nephrogenic diabetes insipidus
,Rationale: Lithium can interfere with the kidney's response to antidiuretic hormone, producing
nephrogenic diabetes insipidus. Patients may develop excessive thirst and urination. Renal
function, serum sodium, and lithium concentrations should be monitored during treatment.
4. Which medication requires particular caution because of the risk of serotonin syndrome
when combined with other serotonergic agents?
A. Sertraline
B. Bupropion
C. Mirtazapine
D. Lamotrigine
Answer: A. Sertraline
Rationale: Sertraline is an SSRI that increases serotonergic activity. Combining serotonergic
medications can increase the risk of serotonin toxicity. Symptoms can include agitation,
diaphoresis, tremor, hyperreflexia, clonus, and hyperthermia.
5. Which antipsychotic is particularly associated with agranulocytosis and requires ANC
monitoring?
A. Aripiprazole
B. Clozapine
C. Haloperidol
D. Ziprasidone
Answer: B. Clozapine
Rationale: Clozapine is associated with potentially severe neutropenia/agranulocytosis.
Appropriate blood-count monitoring is required according to current prescribing and regulatory
requirements. Clozapine is also associated with myocarditis, seizures, metabolic effects, and
severe constipation.
6. Which neurotransmitter is most directly associated with the nigrostriatal pathway?
A. Dopamine
B. Serotonin
C. Acetylcholine
D. Glutamate
Answer: A. Dopamine
,Rationale: The nigrostriatal pathway originates primarily in the substantia nigra and projects to
the striatum. It is important for motor regulation. Dopamine blockade in this pathway is
associated with extrapyramidal symptoms such as dystonia, akathisia, and parkinsonism.
7. A patient taking an antipsychotic develops painful neck contractions and upward
deviation of the eyes. What is the most likely condition?
A. Tardive dyskinesia
B. Acute dystonia
C. Akathisia
D. Neuroleptic malignant syndrome
Answer: B. Acute dystonia
Rationale: Acute dystonia involves sustained muscle contractions and commonly affects the
neck, jaw, eyes, or other muscle groups. It typically occurs relatively soon after starting or
increasing an antipsychotic. Treatment commonly involves an anticholinergic medication such as
benztropine or an antihistamine such as diphenhydramine.
8. Which finding is most characteristic of akathisia?
A. Involuntary tongue movements
B. Severe internal restlessness with an urge to move
C. Sustained neck contraction
D. Lead-pipe rigidity with hyperthermia
Answer: B. Severe internal restlessness with an urge to move
Rationale: Akathisia is characterized by subjective inner restlessness and observable motor
activity, such as pacing or inability to sit still. It can be mistaken for worsening anxiety or
agitation. Recognizing it is important because it may contribute to medication discontinuation or
distress.
9. Which adverse-effect pattern is most concerning for neuroleptic malignant syndrome?
A. Diarrhea and mild tremor
B. Rigidity, hyperthermia, altered mental status, and autonomic instability
C. Increased appetite and sedation
D. Dry mouth and blurred vision
Answer: B. Rigidity, hyperthermia, altered mental status, and autonomic instability
, Rationale: Neuroleptic malignant syndrome is a medical emergency associated with dopamine
blockade. Classic findings include severe muscle rigidity, high fever, altered mental status,
autonomic instability, and elevated creatine kinase. The suspected offending medication should
be stopped and urgent medical management initiated.
10. Which medication is an atypical antidepressant that primarily affects norepinephrine
and dopamine rather than serotonin?
A. Fluoxetine
B. Bupropion
C. Paroxetine
D. Escitalopram
Answer: B. Bupropion
Rationale: Bupropion primarily inhibits norepinephrine and dopamine reuptake. It is generally
less associated with sexual dysfunction than many SSRIs and does not typically cause significant
serotonergic effects. It is contraindicated in patients with seizure disorders and eating disorders
because of increased seizure risk.
11. A patient with major depressive disorder reports depressed mood, anhedonia, insomnia,
fatigue, and poor concentration for several weeks. Which assessment tool is commonly used
to quantify depressive symptoms?
A. GAD-7
B. PHQ-9
C. AUDIT-C
D. AIMS
Answer: B. PHQ-9
Rationale: The PHQ-9 is a validated instrument used to screen for and quantify depressive
symptoms. It can also help monitor symptom changes during treatment. It does not replace a
comprehensive psychiatric evaluation.
12. Which duration is required for generalized anxiety disorder under DSM-5-TR criteria?
A. At least 2 weeks
B. At least 1 month
C. At least 3 months
D. At least 6 months
