Domain 1: Foundations of Psychopathology & Diagnostic Process (12
Questions)
Q1: A 24-year-old graduate student presents to the clinic with complaints of persistent
sadness, difficulty concentrating, and sleep disturbances for the past 3 weeks. She
mentions that her symptoms began after failing an important examination. She denies
any prior psychiatric history, substance use, or medical conditions. Her physical
examination and laboratory results are within normal limits. Which diagnostic principle
should guide the PMHNP's initial approach?
A. Immediately diagnose Major Depressive Disorder based on symptom presentation
alone
B. Rule out substance-induced and medical causes before assigning a primary
psychiatric diagnosis [CORRECT]
C. Diagnose Adjustment Disorder with Depressed Mood without further investigation
D. Presume the symptoms represent normal grief and recommend watchful waiting
Correct Answer: B
Rationale: According to DSM-5-TR diagnostic principles and standard clinical practice,
the PMHNP must first rule out substance/medication-induced disorders and general
,medical conditions that may present with depressive symptoms before assigning a
primary psychiatric diagnosis . This follows the diagnostic hierarchy principle: medical
causes and substance-induced conditions must be excluded first. Option A is incorrect
because diagnosis requires ruling out other causes and ensuring symptoms cause
clinically significant distress or impairment. Option C is premature without first
excluding medical/substance causes. Option D is incorrect because the symptoms (3
weeks duration, functional impairment) exceed normal stress reaction and warrant
formal evaluation.
Q2: A PMHNP is conducting a Cultural Formulation Interview (CFI) with a 35-year-old
immigrant patient experiencing anxiety symptoms. Which component is NOT part of the
core CFI domains as outlined in DSM-5-TR Section III?
A. Cultural definition of the problem
B. Cultural perceptions of cause, context, and support
C. Cultural factors affecting self-coping and past help-seeking
D. Neuropsychological testing results [CORRECT]
Correct Answer: D
Rationale: The DSM-5-TR Cultural Formulation Interview (Section III) includes four core
domains: (1) Cultural Definition of the Problem, (2) Cultural Perceptions of Cause,
Context, and Support, (3) Cultural Factors Affecting Self-Coping and Past Help-Seeking,
and (4) Cultural Factors Affecting Current Help-Seeking . Neuropsychological testing
results, while potentially valuable in certain clinical scenarios, are not part of the CFI
framework. The CFI focuses on understanding cultural identity, the cultural
,conceptualization of distress, psychosocial stressors, and cultural features of
vulnerability and resilience.
Q3: A 42-year-old patient presents with mood symptoms that appear to be directly
caused by hypothyroidism, confirmed by laboratory testing. According to DSM-5-TR
diagnostic hierarchy principles, which diagnosis is most appropriate?
A. Major Depressive Disorder
B. Bipolar Disorder Due to Another Medical Condition
C. Depressive Disorder Due to Another Medical Condition [CORRECT]
D. Substance/Medication-Induced Depressive Disorder
Correct Answer: C
Rationale: When mood symptoms are judged to be the direct physiological
consequence of another medical condition (in this case, hypothyroidism), the
appropriate diagnosis is Depressive Disorder Due to Another Medical Condition . The
diagnostic criteria require: (1) prominent and persistent mood disturbance, (2) evidence
from history/physical/labs that the disturbance is the direct pathophysiological
consequence of another medical condition, (3) disturbance not better explained by
another mental disorder, and (4) not occurring exclusively during delirium.
Hypothyroidism is a well-established medical cause of depressive symptoms through
direct physiological mechanisms.
, Q4: A PMHNP is evaluating a 28-year-old patient who reports hearing voices
commanding him to harm himself. The patient has no other psychotic symptoms, and
medical workup is negative. The voices occur only when the patient is using high doses
of methamphetamine. Which diagnosis best fits this presentation?
A. Schizophrenia
B. Delusional Disorder
C. Substance/Medication-Induced Psychotic Disorder [CORRECT]
D. Brief Psychotic Disorder
Correct Answer: C
Rationale: The presence of prominent hallucinations occurring exclusively in the context
of methamphetamine intoxication, with evidence that the substance is capable of
producing the symptoms, supports a diagnosis of Substance/Medication-Induced
Psychotic Disorder . The key diagnostic requirements include: (1) prominent
hallucinations or delusions, (2) evidence from history/physical/labs that symptoms
developed during or within 1 month of substance intoxication/withdrawal, (3)
disturbance not better explained by a non-substance-induced psychotic disorder, and
(4) not occurring exclusively during delirium. Schizophrenia (A) is incorrect because the
symptoms are substance-related. Delusional Disorder (B) is incorrect because the
presentation involves hallucinations, not delusions, and is substance-related. Brief
Psychotic Disorder (D) requires symptoms not attributable to substance use.
