Introduction
This comprehensive Diagnostic Readiness Test (DRT) is designed to
prepare Psychiatric-Mental Health Nurse Practitioner candidates for the
Barkley Diagnostic Readiness Test and the ANCC PMHNP-BC certification
examination. The assessment evaluates critical knowledge areas including
psychopharmacology, DSM-5-TR diagnostic criteria, psychotherapy
modalities, ethical-legal compliance, and clinical decision-making in real-
world psychiatric scenarios. All 100 multiple-choice questions mirror the
structure, difficulty, and content distribution of the actual certification
exam, emphasizing applied professional competence over rote
memorization. Success requires mastery of foundational theory, regulatory
standards, and evidence-based treatment planning across the lifespan.
Each question includes a detailed rationale to reinforce learning and
enhance clinical reasoning.
SECTION ONE: QUESTIONS 1–100
Question 1
A 45-year-old patient presents with anhedonia, fatigue, and sleep
disturbances for the last two months. As a Psychiatric-Mental Health
Nurse Practitioner (PMHNP), which initial diagnostic step is most
appropriate?
A. Order a brain MRI
B. Conduct a comprehensive psychiatric interview
,C. Begin antidepressant therapy immediately
D. Recommend mindfulness training
B. Conduct a comprehensive psychiatric interview
RATIONALE: A comprehensive psychiatric interview allows for a
thorough assessment of history, symptoms, and differential diagnoses
before initiating treatment. Imaging (A) is reserved for suspected
neurological causes, and interventions (C, D) should follow a confirmed
assessment.
Question 2
Which neurotransmitter imbalance is most closely associated with the
positive symptoms of schizophrenia?
A. Decreased serotonin
B. Increased dopamine
C. Decreased glutamate
D. Increased GABA
B. Increased dopamine
RATIONALE: Hyperactivity of dopamine in the mesolimbic pathway
is linked to hallucinations and delusions—core positive symptoms of
schizophrenia.
Question 3
A 24-year-old male presents with 3 weeks of decreased need for sleep,
pressured speech, grandiose delusions about being a billionaire, and
risky sexual behavior. He has no history of depression. Which
medication is the FIRST-LINE treatment for acute stabilization?
A. Fluoxetine
B. Lithium
, C. Haloperidol
D. Lamotrigine
B. Lithium
RATIONALE: Lithium is first-line for acute mania in bipolar I disorder
without depressive history. Fluoxetine (antidepressant) can worsen
mania. Haloperidol may be used for severe agitation but is not first-line
monotherapy. Lamotrigine is for bipolar depression maintenance, not
acute mania.
Question 4
According to DSM-5-TR, what is the MINIMUM duration required to
diagnose persistent depressive disorder (dysthymia)?
A. 2 weeks
B. 1 month
C. 6 months
D. 2 years
D. 2 years
RATIONALE: DSM-5-TR requires depressed mood for most of the
day, for more days than not, for at least 2 years in adults (1 year in
children/adolescents) to diagnose persistent depressive disorder.
Question 5
A patient on clozapine requires monitoring for which life-threatening
adverse effect?
A. Nephrotoxicity
B. Agranulocytosis
C. Hepatotoxicity
D. QT prolongation
