, Barkley PMHNP Certification Exam Questions
and Answers with Rationale 2026/2027
Question 1
A 35-year-old male presents with a 3-week history of depressed mood,
profound anhedonia, early morning awakening, psychomotor
retardation, and active suicidal ideation with a plan. What is the most
appropriate immediate intervention?
A. Outpatient referral for cognitive-behavioral therapy
B. Immediate psychiatric hospitalization for safety evaluation
C. Initiation of a trial of fluoxetine with weekly follow-up
D. Prescription of a low-dose benzodiazepine for sleep
Correct Answer: B. Immediate psychiatric hospitalization for safety
evaluation
Rationale: The presence of active suicidal ideation with a plan, coupled
with severe vegetative symptoms (early morning awakening,
psychomotor retardation) and major depressive episode criteria,
indicates an imminent risk to safety. Inpatient stabilization is the highest
priority before initiating outpatient psychotherapy or pharmacotherapy.
Outpatient management is unsafe when active suicidal intent and a plan
are present. Benzodiazepines do not treat underlying depression and can
disinhibit or worsen depression risk.
Question 2
A 42-year-old female with a history of schizophrenia who has been
stable on oral risperidone for five years presents with involuntary,
rhythmic movements of her tongue, puckering of her lips, and facial
grimacing. Which diagnostic tool is most appropriate to evaluate and
quantify these findings?
, A. Young Mania Rating Scale (YMRS)
B. Abnormal Involuntary Movement Scale (AIMS)
C. Clinical Global Impression (CGI)
D. Positive and Negative Syndrome Scale (PANSS)
Correct Answer: B. Abnormal Involuntary Movement Scale (AIMS)
Rationale: The patient is exhibiting classic signs of tardive dyskinesia
(TD), a late-onset, potentially irreversible extrapyramidal symptom
resulting from long-term dopamine antagonist blockade. The AIMS is
the standard, validated clinician-rated tool used to monitor and quantify
these abnormal involuntary movements. The PANSS measures
schizophrenia symptom severity, the YMRS measures mania, and the
CGI evaluates global illness severity.
Question 3
A 28-year-old male is started on sertraline 50 mg daily for major
depressive disorder. Two weeks later, he presents with acute
restlessness, an inability to sit still, pacing back and forth, and subjective
inner jitteriness. This clinical presentation is most consistent with:
A. A panic attack
B. Akathisia
C. Serotonin discontinuation syndrome
D. Acute dystonic reaction
Correct Answer: B. Akathisia
Rationale: Akathisia is a common extrapyramidal or medication-
induced movement side effect characterized by an inner subjective
sense of restlessness and a compelling need to move or pace. It can
be triggered by SSRIs due to serotonin-mediated inhibition of
dopaminergic pathways. It differs from anxiety because of the core
physical motor restlessness and distress specifically linked to
medication changes. Acute dystonia involves painful muscle
, spasms, and serotonin discontinuation occurs upon stopping
medications rather than initiating them.
Question 4
A patient diagnosed with bipolar I disorder is currently stabilized on
lithium carbonate. They present for routine monitoring. Which baseline
and ongoing laboratory parameters must be regularly assessed due to the
long-term physiological risks associated with lithium therapy?
A. Complete blood count (CBC) and liver function tests (LFTs)
B. Serum creatinine, blood urea nitrogen (BUN), and thyroid-
stimulating hormone (TSH)
C. Fasting lipid panel and hemoglobin A1c
D. Serum amylase and lipase levels
Correct Answer: B. Serum creatinine, blood urea nitrogen (BUN), and
thyroid-stimulating hormone (TSH)
Rationale: Lithium is excreted almost exclusively by the kidneys
and can lead to nephrogenic diabetes insipidus or chronic
tubulointerstitial nephropathy over time; thus, renal function (BUN
and creatinine) must be tracked regularly. Lithium also commonly
alters thyroid function, causing hypothyroidism, requiring periodic
TSH monitoring. CBC and LFTs are primary monitors for
valproate or carbamazepine, while lipids and HbA1c monitor
second-generation antipsychotic metabolic changes.
Question 5
A 50-year-old patient with treatment-resistant schizophrenia is placed on
clozapine therapy. Prior to initiating treatment and continuously
throughout therapy, which specific laboratory parameter must be closely
tracked to mitigate a life-threatening adverse reaction?
A. Absolute Neutrophil Count (ANC)
B. Serum potassium level
