Section 1: Foundations of Psychiatric Assessment
Q1. Which statement best reflects the DSM-5-TR (Text Revision, 2022) as used in psychiatric
assessment?
A. It replaced categorical diagnostic criteria with a purely dimensional system of classification
B. It removed all Z codes so that suicidal behavior is no longer codable
C. It added prolonged grief disorder as a new formal diagnosis [CORRECT]
D. It retired all severity and course specifiers from the manual
Correct Answer: C
Rationale: The DSM-5-TR, released in March 2022, retained the categorical polythetic criteria
structure and added prolonged grief disorder, along with updated criteria text for more than 70 disorders
and new codes for suicidal behavior and nonsuicidal self-injury. The manual continues to use
dimensional specifiers, retains Z codes, and keeps severity and course specifiers, so the other options
misstate the 2026/2027 assessment standard emphasized in NR 548.

Q2. A PMHNP documents a new patient as having recurrent major depressive disorder, moderate,
and assigns ICD-10-CM code F33.1. What is the primary purpose of this coding practice in
psychiatric assessment?
A. The code replaces the narrative diagnostic formulation in the medical record
B. The code standardizes communication, billing, epidemiologic tracking, and documentation of the
diagnosis [CORRECT]
C. The code legally establishes that the diagnosis is beyond question
D. The code mandates a specific pharmacologic treatment plan
Correct Answer: B
Rationale: ICD-10-CM codes such as F33.1 allow clinicians, payers, researchers, and health systems to
share a standardized language for psychiatric diagnoses, supporting documentation, reimbursement, and
population health tracking, which is a core documentation standard in NR 548. A code never replaces
the biopsychosocial formulation, does not make a diagnosis legally irrefutable, and does not dictate
treatment.
Q3. A new patient tells the PMHNP, 'I feel terrible and I cannot go on like this.' According to sound
diagnostic reasoning taught in NR 548, what is the best next step?
A. Begin with broad, open-ended exploration of the chief complaint and history of present illness,
then narrow with focused questions to build a differential diagnosis [CORRECT]
B. Assign a provisional diagnosis from the wording of the chief complaint alone and document it
immediately
C. Administer a full Mini-Mental State Examination before obtaining any history
D. Select the most likely diagnosis first and then ask only questions that confirm it
Correct Answer: A
Rationale: Evidence-based diagnostic reasoning begins with open-ended exploration to establish the
chronology, severity, and context of the presenting problem, after which the clinician narrows the field
with targeted questions and screening tools. Diagnosing from the chief complaint wording, testing
before history-taking, or asking confirmatory questions only reflects premature closure and
confirmation bias, two of the most common diagnostic errors.
Q4. Which description of the Cultural Formulation Interview (CFI) is accurate?
A. It is a 16-item semi-structured interview in DSM-5 Section III used to elicit the patient's cultural
definition of the problem, perceived causes, coping efforts, and supports [CORRECT]
B. It is a standardized psychometric test that quantifies acculturation on a 100-point scale
C. It is a billing instrument used to justify interpreter services
D. It replaces the mental status examination when evaluating culturally diverse patients
Correct Answer: A
Rationale: The CFI is a set of 16 semi-structured questions, with supplementary informant and domain
modules, published in DSM-5 Section III to help clinicians systematically gather cultural identity,
explanatory models, stressors, and supports. It supplements, rather than replaces, the clinical interview
and mental status examination, and it is not a scored psychological test or a billing tool.

Q5. A 36-year-old patient meets full criteria for major depressive disorder and also has severe
alcohol use disorder with withdrawal episodes. Following DSM-5-TR assessment principles, which
statement is correct?
A. Only the alcohol use disorder should be coded until abstinence has been maintained for one year
B. Only the depressive disorder should be coded because mood symptoms dominate the
presentation
C. Both diagnoses should be assigned when each independently warrants clinical attention and the
depressive episodes are not limited to intoxication or withdrawal [CORRECT]
D. Comorbid diagnoses are avoided in psychiatry because they impair treatment planning
Correct Answer: C
Rationale: DSM-5-TR permits, and good practice requires, assigning multiple diagnoses when each is
sufficiently distinct and independently warrants clinical attention, so comorbid depression and alcohol
use disorder are both coded. The substance-induced alternative is reserved for symptoms confined to
intoxication or withdrawal, and avoiding comorbid diagnoses would fragment care and violate accurate
documentation standards.
Q6. In psychiatric documentation, what is the difference between a 'provisional' diagnosis and a 'rule
out' diagnosis?
A. Provisional means the clinician believes the patient does not have the disorder; rule out means
the disorder is confirmed
B. The two terms are interchangeable and carry no documentation implications
C. Provisional diagnoses may only be used for personality disorders
D. Provisional means the clinician believes the disorder is likely but information is insufficient; rule
out means the condition is being considered but is not currently believed present [CORRECT]
Correct Answer: D
Rationale: A provisional diagnosis signals the clinician's best current impression that the disorder is
present while additional data are gathered, whereas rule out communicates a differential possibility that
requires verification but is not believed to be the working diagnosis. Using these qualifiers precisely is a
documentation standard in NR 548 because imprecise qualifiers distort risk, communication, and
follow-up planning.

Q7. A PMHNP evaluates a 24-year-old with fatigue and low mood and, based on the first few
minutes of the interview, commits to a diagnosis of major depressive disorder. Despite later
disclosure of prominent grandiosity, racing thoughts, and four days of no sleep before the visit, the
NP does not revisit the initial impression. This error pattern is best described as:
A. Availability bias
B. Anchoring with premature closure [CORRECT]
C. Base-rate neglect
D. Representativeness bias
Correct Answer: B
Rationale: Anchoring occurs when the clinician fixes on an initial impression and premature closure
occurs when the search stops before alternatives, such as bipolar disorder, are considered, even when
new information contradicts the anchor. This is dangerous here because antidepressant treatment of
unrecognized bipolar disorder can precipitate mania or rapid cycling; availability, base-rate, and
representativeness biases describe different reasoning failures.
Q8. After a patient mentions anxiety, an NP spends the rest of the interview asking exclusively about
anxiety symptoms, never exploring sleep, energy, or Elevated mood despite the patient's comment
that she 'has not slept in days and feels wired.' The cognitive bias most demonstrated is:
A. Confirmation bias [CORRECT]
B. Framing effect
C. Diagnostic momentum
D. Hindsight bias
Correct Answer: A
Rationale: Confirmation bias is the selective seeking and interpretation of data that support an initial
hypothesis while ignoring disconfirming evidence, which is exactly what happens when only anxiety
questions are asked. Diagnostic momentum would involve the label being carried forward by the record
or prior clinicians, while framing and hindsight biases describe other distortions of judgment.
Q9. Which statement about the Structured Clinical Interview for DSM-5 (SCID-5) is accurate?
A. It is a fully self-administered online questionnaire completed without a clinician
B. It is a semi-structured, criterion-referenced diagnostic interview considered a benchmark for
establishing DSM-5 diagnoses [CORRECT]
C. It is a brief 15-minute screening tool designed for waiting-room use
D. It generates medication recommendations based on symptom counts
Correct Answer: B
Rationale: The SCID-5 is a clinician-administered, semi-structured interview that maps systematically
onto DSM-5 criteria and is widely regarded as a gold-standard assessment for establishing diagnoses in
research and complex clinical cases. It requires trained administration, takes substantially longer than
brief screens such as the MINI, and makes no treatment recommendations.
