This comprehensive examination guide is designed to prepare candidates for the
Barkley & Associates PMHNP Certification Exam. The examination evaluates
advanced practice nursing knowledge essential for the Psychiatric-Mental Health
Nurse Practitioner role, including psychiatric assessment, differential diagnosis,
psychopharmacology, and evidence-based treatment planning. Questions are
structured to assess clinical reasoning, prioritization, and the application of
psychiatric-mental health concepts to real-world patient scenarios. Each item
includes a verified correct answer accompanied by a detailed rationale to reinforce
learning and support exam preparation for the 2026/2027 academic year.
,SECTION ONE: QUESTIONS 1 – 100
Question 1
A 28-year-old female with a history of PTSD presents with flashbacks,
hypervigilance, and nightmares. She reports using alcohol to help her sleep. What
is the most appropriate first-line pharmacologic intervention for her nightmares?
A. Quetiapine 25 mg at bedtime
B. Prazosin 1 mg at bedtime
C. Trazodone 50 mg at bedtime
D. Hydroxyzine 25 mg at bedtime
B. Prazosin 1 mg at bedtime
RATIONALE: Prazosin is an alpha-1 antagonist with robust evidence for
reducing trauma-related nightmares in PTSD . While trazodone and quetiapine
are used for sleep, prazosin is the guideline-supported first-line agent specifically
for PTSD-associated nightmares. The dose should be titrated slowly to avoid
hypotension.
Question 2
A 45-year-old male with major depressive disorder (MDD) has been on fluoxetine
40 mg for 8 weeks with partial response. He reports anorgasmia. What is the best
next step?
A. Add bupropion 150 mg daily
B. Switch to sertraline
C. Increase fluoxetine to 60 mg
D. Add mirtazapine 15 mg at bedtime
A. Add bupropion 150 mg daily
RATIONALE: Bupropion is often added to SSRIs to counteract sexual side
effects like anorgasmia, as it increases dopamine and norepinephrine . Switching
,to another SSRI like sertraline may not resolve the issue, as sexual dysfunction is a
class effect. Increasing the dose would likely worsen the side effect.
Question 3
A PMHNP is reviewing a patient's chart and notes the phrase "blunted affect."
Which clinical presentation best correlates with this documentation?
A. A complete lack of emotional expression
B. A wide range of emotional expression with rapid shifts
C. A significant reduction in the intensity of emotional expression
D. Emotional expression that is incongruent with the situation
C. A significant reduction in the intensity of emotional expression
RATIONALE: Blunted affect refers to a marked reduction in the intensity of
emotional expression . Flat affect is the complete absence of emotional
expression. Labile affect refers to rapid shifts, and inappropriate affect is
incongruent with the content of discussion.
Question 4
A patient with bipolar I disorder is stabilized on lithium 900 mg/day. Their current
lithium level is 1.2 mEq/L. They present with coarse tremor, nausea, and
confusion. What is the priority intervention?
A. Increase lithium to 1200 mg/day
B. Add propranolol for tremor
C. Hold lithium and assess renal function
D. Add ondansetron for nausea
C. Hold lithium and assess renal function
RATIONALE: The symptoms (coarse tremor, nausea, confusion) with a level of
1.2 mEq/L indicate early lithium toxicity, especially if the patient is dehydrated or
has renal impairment . Lithium should be held, and renal function and level
, should be rechecked immediately. Neurological symptoms in lithium toxicity
require urgent attention.
Question 5
Which lab monitoring is necessary for a patient starting lithium?
A. CBC and LFTs
B. Serum lithium, renal function, thyroid function
C. Fasting glucose and lipids
D. TSH only
B. Serum lithium, renal function, thyroid function
RATIONALE: Lithium is renally cleared and can affect thyroid function; regular
monitoring prevents toxicity . Baseline monitoring includes serum creatinine,
BUN, TSH, and serum lithium levels. Ongoing monitoring is essential due to
lithium's narrow therapeutic index.
Question 6
A 25-year-old patient presents with flat affect, social withdrawal, and impaired
motivation for 6 months. There are no psychotic symptoms. What is the most
likely diagnosis?
A. Schizophrenia
B. Schizoaffective Disorder
C. Major Depressive Disorder with psychotic features
D. Schizoid Personality Disorder
D. Schizoid Personality Disorder
RATIONALE: Long-standing social detachment, flat affect, and limited emotion
indicate a personality disorder rather than acute psychotic illness . Schizoid
personality disorder is characterized by a pervasive pattern of detachment from
social relationships and a restricted range of emotional expression.
