Barkley DRT 1 Exam | Actual Questions and Answers
Latest Updated 2026/2027 (Graded A+)
SECTION I: Clinical Assessment & Diagnostic Reasoning
1. What does diagnostic reasoning allow the PMHNP to do?
A. Prescribe medication without assessment
B. Focus on what needs to be asked and examined, cluster abnormal findings,
develop differential diagnoses, and analyze/interprete findings
C. Make a diagnosis based on a single symptom
D. Bypass the physical examination
Rationale: Diagnostic reasoning enables the provider to focus assessment,
cluster findings, develop differentials, and interpret results systematically. This is
foundational to clinical decision-making. It is not a shortcut to prescribing (A),
cannot rely on a single symptom (C), and does not bypass physical examination
(D).
2. When taking a History of Present Illness (HPI), the mnemonic OLD CART stands
for:
A. Onset, Location, Duration, Character, Aggravating factors, Relieving factors,
Treatment
B. Only, Location, Diagnosis, Character, Assessment, Referral, Time
C. Onset, Level, Duration, Cause, Aggression, Relief, Timing
D. Observation, Location, Duration, Condition, Aggravation, Resolution, Therapy
Rationale: OLD CART is a comprehensive mnemonic for HPI data
collection: Onset (when did it start?), Location (where is it?), Duration (how long
does it last?), Character (what does it feel like?), Aggravating/Associating factors
(what makes it worse?), Relieving factors (what makes it better?), and Treatment
(what has been tried?). The other options contain fabricated mnemonics.
3. Inductive reasoning in clinical practice is defined as:
A. Moving from general principles to specific conclusions
B. Moving from specific findings or complaints to more general patterns or
,diagnoses
C. Relying solely on evidence-based guidelines
D. Using intuition without data
Rationale: Inductive reasoning involves building general conclusions from
specific observations. In clinical practice, this means starting with patient-specific
findings and moving toward broader diagnostic patterns. Option A describes
deductive reasoning, not inductive.
4. The correct order to complete a patient visit is:
A. Assessment, Plan, HPI, Physical Exam, ROS
B. Chief complaint, HPI, Past medical history, Social history, Family history, ROS,
Physical exam, Diagnostic tests
C. Physical exam, HPI, ROS, Plan
D. ROS, HPI, Physical exam, Assessment, Plan
Rationale: The standard clinical sequence begins with the chief complaint,
followed by HPI, past medical history, social history, family history, and ROS
(subjective data), then physical exam and diagnostic tests (objective data),
culminating in assessment and plan.
5. A PMHNP is assessing a new patient. Which component of the psychiatric
evaluation is most critical for establishing a differential diagnosis?
A. Review of systems
B. Mental status examination
C. Family history
D. Physical examination
Rationale: The mental status examination provides objective data about
the patient's appearance, behavior, mood, affect, thought process, thought
content, cognition, and insight — all essential for distinguishing between
psychiatric disorders. While other components contribute, the MSE is the
cornerstone of psychiatric diagnostic assessment.
6. Which of the following is considered a positive symptom of schizophrenia?
,A. Flat affect
B. Avolition
C. Auditory hallucinations
D. Anhedonia
Rationale: Positive symptoms reflect an excess or distortion of normal
function and include hallucinations, delusions, disorganized speech, and grossly
disorganized behavior. Flat affect, avolition, and anhedonia are negative
symptoms reflecting diminishment of normal function.
7. A 45-year-old female presents with new-onset obsessive-compulsive behaviors.
Which lab test best screens for secondary causes?
A. ANA
B. TSH
C. ESR
D. Glucose
Rationale: Thyroid dysfunction can mimic or precipitate anxiety and
obsessive behaviors; a thyroid screen helps rule out endocrine contribution. ANA
is useful for autoimmune screening but is not first-line for OCD. ESR and glucose
are nonspecific.
8. The PMHNP discusses informed consent. Which element must be verified for
true "capacity"?
A. Agreement with provider recommendation
B. Ability to understand, appreciate, reason, and express a choice
C. Signing a form in the presence of a witness
D. Absence of mental illness
Rationale: Decisional capacity rests on cognitive ability — not diagnosis —
to comprehend and rationally weigh treatment options. It requires
understanding, appreciation, reasoning, and expression of choice. Signing a form
(C) is documentation, not capacity itself. Mental illness does not automatically
negate capacity (D).
9. Which symptom would be considered part of negative schizophrenia
symptoms?
, A. Auditory hallucinations
B. Paranoid delusions
C. Flat affect
D. Pressured speech
Rationale: Negative symptoms reflect diminishment of normal function —
blunted affect, anhedonia, avolition — whereas hallucinations and delusions are
positive symptoms. Pressured speech is more characteristic of mania.
10. A PMHNP is differentiating between delirium and dementia. Which feature is
most consistent with delirium?
A. Insidious onset
B. Stable, non-fluctuating course
C. Fluctuating level of consciousness
D. Preserved attention
Rationale: Delirium has an acute onset with fluctuating consciousness and
attention deficits. Dementia typically has insidious onset, stable progression, and
relatively preserved consciousness until late stages.
11. Which of the following best describes "tangential thinking"?
A. Jumping from one topic to another with no logical connection
B. Going off on a tangent and never returning to the original point
C. Giving overly detailed, lengthy answers
D. Making up new words
Rationale: Tangential thinking occurs when a patient drifts from the topic
and never returns to the original point. Flight of ideas (A) involves rapid topic
jumps that are loosely connected. Circumstantiality (C) involves excessive detail
but eventually returns to the point. Neologisms (D) are invented words.
12. A patient reports hearing voices that others do not hear. This is an example of:
A. Illusion
B. Hallucination
C. Delusion
D. Depersonalization
