A psychiatric nurse practitioner is evaluating a new patient who reports hearing voices telling them to harm
others. According to the DSM-5-TR clinical reasoning framework, which step should the clinician prioritize
first?
A. A. Rule out substance-induced etiology
B. B. Apply a specific psychiatric diagnosis
C. C. Conduct a comprehensive biopsychosocial assessment
D. D. Rule out malingering or factitious behavior [CORRECT]
Correct Answer: D
Rationale: The DSM-5-TR clinical reasoning framework prioritizes ruling out malingering and factitious behavior first, as these
represent intentional symptom production. Substance-induced etiology is ruled out second, followed by medical conditions, and then
specific psychiatric diagnoses are considered. Beginning with a specific diagnosis without ruling out malingering could lead to
inappropriate treatment.
Which of the following best describes the biopsychosocial model as applied to psychiatric differential
diagnosis?
A. A. A framework that exclusively examines biological factors such as genetics and neurochemistry
B. B. A model emphasizing psychological factors while minimizing social determinants of health
C. C. An integrative approach considering biological, psychological, and social factors in symptom etiology
[CORRECT]
D. D. A hierarchical model prioritizing social factors above biological and psychological contributors
Correct Answer: C
Rationale: The biopsychosocial model integrates biological (genetics, neurochemistry), psychological (cognition, coping), and social
(culture, environment) factors to understand psychiatric symptoms holistically. Options A and B are incomplete because they exclude
key domains. Option D is incorrect because no single domain is prioritized over others in this framework.
A 28-year-old patient presents with depressive symptoms after a recent job loss. The clinician notes the
patient grew up in a culture where emotional distress is expressed through somatic complaints. Which
concept is most relevant to accurate diagnosis?
A. A. Cultural formulation interview to assess culturally bound expressions of distress [CORRECT]
B. B. Ignoring cultural factors and applying standard DSM-5-TR criteria uniformly
C. C. Assuming somatic complaints indicate a medical condition rather than depression
D. D. Applying diagnostic criteria developed exclusively for Western populations
Correct Answer: A
Rationale: The DSM-5-TR emphasizes cultural considerations through the Cultural Formulation Interview, which helps clinicians
understand culturally specific expressions of distress such as somatization. Ignoring cultural factors (option B) may lead to
misdiagnosis. Somatic complaints can represent depression in certain cultures (option C is premature). DSM-5-TR criteria are designed
to be cross-culturally applicable (option D is incorrect).
When evaluating a patient with new-onset psychotic symptoms, what is the correct order of the DSM-5-TR
differential diagnosis reasoning steps?
A. A. Medical conditions, substance-induced, malingering, specific psychiatric diagnosis
B. B. Malingering, substance-induced, medical conditions, specific psychiatric diagnosis [CORRECT]
C. C. Specific psychiatric diagnosis, substance-induced, medical conditions, malingering
D. D. Substance-induced, medical conditions, malingering, specific psychiatric diagnosis
Correct Answer: B
