PMHNP Exam Reported Questions with Correct Verified
Answers -Latest Update 2026.
Question 1
A patient with schizophrenia is started on a new antipsychotic
medication. The PMHNP understands that atypical
antipsychotics work primarily on which neurotransmitter
systems?
A. Dopamine and acetylcholine
B. Serotonin and norepinephrine
C. Dopamine and serotonin
D. GABA and glutamate
Answer: C. Dopamine and serotonin
Rationale: Atypical antipsychotics (second-generation) act as
antagonists at both dopamine D2 receptors and serotonin 5-
HT2A receptors. This dual action is believed to contribute to their
efficacy in treating both positive and negative symptoms of
1
,schizophrenia while producing fewer extrapyramidal side effects
compared to typical antipsychotics. The serotonin-dopamine
balance theory suggests that 5-HT2A blockade allows for
improved dopamine release in specific brain regions .
Question 2
When an unstable patient asks why it is necessary to add
medications to his current regimen, the PMHNP's best
response would be:
A. "Your current medication is not working, so we need to try
something different."
B. "Adding another medication will make your current medication
work better."
C. "Many psychiatric illnesses involve several dysfunctional
neurotransmitter systems. Often, a single medication may only
affect one or two of these systems. The addition of another
medication can work with the current medication in stabilizing
2
,multiple neurotransmitter systems and help alleviate your
symptoms."
D. "You need more medication because your illness is severe."
Answer: C
Rationale: This response provides psychoeducation that is
accurate, patient-centered, and explains the rationale for
polypharmacy in psychiatric treatment. It acknowledges the
complexity of psychiatric disorders and helps build therapeutic
alliance by validating the patient's concern while providing
evidence-based information .
Question 3
A patient is prescribed 50 mg of desvenlafaxine to take every
other day for major depressive disorder. What does the
PMHNP understand about this patient?
A. The patient has mild hepatic impairment
B. The patient is elderly
3
, C. The patient has severe renal impairment
D. The patient has a history of non-adherence
Answer: C. The patient has severe renal impairment
Rationale: Desvenlafaxine is primarily eliminated renally. For
patients with severe renal impairment (creatinine clearance <30
mL/min), the recommended dose is 50 mg every other day. This
dosing adjustment prevents accumulation and reduces the risk of
adverse effects .
Question 4
A patient diagnosed with bipolar disorder without mania asks
the PMHNP why he is being prescribed a mood stabilizer.
What is the appropriate response?
A. "Mood stabilizers only treat mania, not depression."
B. "This medication will cure your bipolar disorder."
C. "Mood stabilizers can target mania and mania relapse and
also reduce symptoms of bipolar depression and relapse of
