Barkley PMHNP Diagnostic Readiness Test (DRT)
#2 – 100 Predictor Questions & Verified Answers
The following comprehensive test bank is designed to simulate the difficulty and content coverage of the Barkley
& Associates Diagnostic Readiness Test (DRT) #2 for Psychiatric-Mental Health Nurse Practitioner
(PMHNP) certification. Each question is presented in a clinical vignette format and is followed by the correct
answer and a detailed, evidence-based rationale.
PART I – CLINICAL ASSESSMENT & DIAGNOSIS (Questions 1–25)
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
Answer: B
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.
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
pg. 1
,2
Answer: B
Rationale: Hyperactivity of dopamine in the mesolimbic pathway is linked to the
positive symptoms of schizophrenia (hallucinations, delusions). Most
antipsychotics exert their therapeutic effect by blocking dopamine D2 receptors.
3. Which antidepressant carries the highest risk of hypertensive crisis when
combined with tyramine-rich food?
A) Fluoxetine
B) Bupropion
C) Phenelzine
D) Sertraline
Answer: C
Rationale: Phenelzine is a monoamine oxidase inhibitor (MAOI). MAOIs inhibit the
metabolism of tyramine, leading to hypertensive crisis if tyramine-rich foods
(aged cheese, cured meats, fermented foods) are consumed. SSRIs and bupropion
do not carry this risk.
4. A patient with panic disorder shows reduced heart rate variability (HRV). Which
neurotransmitter system is most directly responsible?
A) Dopamine
B) Norepinephrine
C) GABA
D) Acetylcholine
Answer: B
Rationale: Low HRV reflects sympathetic overdrive and reduced parasympathetic
tone. Norepinephrine dysregulation is central in panic disorder, with increased
noradrenergic activity in the locus coeruleus contributing to autonomic
hyperarousal and tachycardia.

5. Hyperactivity of which brain region is most consistently found in PTSD
hyperarousal?
A) Hippocampus
B) Prefrontal cortex
C) Amygdala
D) Thalamus
Answer: C
Rationale: Amygdala hyperreactivity to threat cues is the primary driver of
hyperarousal symptoms in PTSD. The amygdala serves as the brain’s fear center,
and in PTSD it becomes overactive, leading to exaggerated startle response and
hypervigilance.
6. A patient presents with symptoms of an anxiety disorder. Labs show elevated
serotonin and norepinephrine and decreased GABA. Which part of the brain is
most involved in the patient’s disorder?
A) Orbital frontal cortex
B) Raphe nucleus
C) Amygdala
D) Nucleus accumbens
Answer: B
Rationale: The raphe nucleus is the primary source of serotonin in the brain.
Serotonin dysfunction is implicated in anxiety disorders, including GAD, panic
disorder, and OCD. The orbital frontal cortex is involved in decision-making, the
amygdala in fear, and the nucleus accumbens in reward.
7. An 89-year-old Hispanic female with cirrhosis refuses liver replacement
surgery, stating: “If God wanted me to die this way, then I will not interfere with
His will, and I will bear suffering.” According to the literature, which cultural issue
does her statement reflect?
A) Value orientation
B) Activity orientation
pg. 3
, 4
C) Family roles
D) Time orientation
Answer: C
Rationale: The patient’s statement reflects a belief system where religious faith
and submission to divine will take precedence over medical intervention. This is
often associated with specific cultural and family roles where decisions may be
influenced by religious beliefs and the expectation to accept suffering as part of
God’s plan.
8. You are seeing a first-time patient for a physical exam and need to perform a
cultural assessment. Which question or statement would be most appropriate?
A) “Fasting is not recommended as it can adversely affect your health.”
B) “If I am going to be your provider, you should learn English so we can
communicate.”
C) “I am going to touch your face to inspect your eyes.”
D) “Do you identify yourself as male or female?”
Answer: D
Rationale: This question respects the patient’s self-identity and is part of a
respectful, non-judgmental cultural assessment. It allows the patient to share
their gender identity without assumption, promoting trust and open
communication. The other options are either culturally insensitive (B),
presumptive (A), or may not be appropriate without first explaining the reason for
the action (C).
9. A patient with a history of substance abuse and a family history of mood
disorders presents with fatigue, insomnia, confusion, weight loss, and recurrent
suicidal thoughts. Which medication is the best choice for his situation?
A) Sympathomimetics
B) Bupropion
C) Olanzapine
D) Risperidone
