The Barkley DRT PMHNP Diagnostic Readiness Test is a comprehensive, evidence-based practice examination
designed to simulate the rigor and clinical application required for the Psychiatric-Mental Health Nurse
Practitioner certification exam. Developed by Barkley & Associates, this 100-question online assessment—
complete with detailed rationales and illustrative graphs—helps students pinpoint areas of strength and
weakness, allowing for targeted remediation before sitting for the national certification exam. The PMHNP
certification examination itself is an entry-level competency-based exam that tests clinical knowledge of
psychiatric mental health across the lifespan, consisting of 150 multiple-choice questions evaluating readiness
for advanced nursing practice. The exam is structured around four core domains: Assess, Diagnose, Plan, and
Evaluate, with knowledge areas spanning scientific foundations, pharmacology, nonpharmacological therapies,
psychotherapies, assessment and diagnosis, care practices, and professional role. This question bank provides
200 advanced, scenario-based multiple-choice questions that mirror the difficulty and clinical reasoning
required on the actual exam. Each question is accompanied by a detailed rationale explaining why the correct
answer is right and why the distractors are wrong. By working through these high-yield questions, candidates
will sharpen their diagnostic reasoning, psychopharmacologic decision-making, and ethical judgment—
maximizing their chances of passing on the first attempt.

QUESTIONS 1-200
Q1: A 34-year-old male presents with persistent depressed mood,
anhedonia, and sleep disturbance for 8 weeks. He reports guilt and
difficulty concentrating. He denies any history of manic or hypomanic
episodes. Which of the following is the most appropriate initial
diagnostic step?
A) Initiate a selective serotonin reuptake inhibitor (SSRI) immediately
B) Conduct a comprehensive psychiatric evaluation including medical
history and laboratory testing
C) Refer for electroconvulsive therapy (ECT)
D) Diagnose major depressive disorder based on the presence of two
symptoms
Rationale: The correct answer is B. A comprehensive psychiatric
evaluation is essential before initiating treatment to rule out medical
causes and confirm the diagnosis. Option A is incorrect because
pharmacotherapy should follow a thorough assessment. Option C is
incorrect because ECT is reserved for severe or treatment-resistant
cases. Option D is incorrect because MDD requires at least five
symptoms for a minimum of two weeks.
Q2: A 28-year-old female with a history of bipolar I disorder is
currently manic and refuses medication. She has not slept for three
days and is exhibiting grandiosity and risky behaviors. What is the
most appropriate immediate intervention?
A) Outpatient therapy and mood stabilizer initiation
B) Voluntary psychiatric hospitalization
C) Involuntary psychiatric hospitalization
D) Family therapy and psychoeducation
Rationale: The correct answer is C. Involuntary hospitalization is
, 4
indicated when a patient poses a danger to self or others or is unable
to care for themselves due to mental illness. Option A is insufficient
because the patient is acutely manic and refusing treatment. Option
B is not possible because the patient refuses. Option D is not the
immediate priority in an acute safety crisis.
Q3: A 45-year-old male with schizophrenia has been stable on
haloperidol for 5 years. He now presents with involuntary
movements of the tongue and face. Which medication is most
appropriate for this condition?
A) Benztropine
B) Valbenazine
C) Propranolol
D) Lorazepam
Rationale: The correct answer is B. Valbenazine is a VMAT2 inhibitor
approved for tardive dyskinesia, which is characterized by involuntary
movements. Option A treats acute dystonia, not tardive dyskinesia.
Option C treats akathisia. Option D treats catatonia or acute
agitation, not tardive dyskinesia.
Q4: A 22-year-old college student presents with panic attacks that
occur unexpectedly. She fears having another attack and avoids
crowded places. Which of the following is the first-line pharmacologic
treatment?
A) Alprazolam
B) Sertraline
C) Quetiapine
D) Lithium
Rationale: The correct answer is B. SSRIs are first-line for panic
disorder. Option A is a benzodiazepine used short-term but not first-
line due to dependence risk. Option C is an antipsychotic not indicated
for panic disorder. Option D is a mood stabilizer for bipolar disorder.
