Section 1: Foundations of Psychopathology & Diagnostic Reasoning
(Questions 1–12)
Q1: A 28-year-old patient from a Southeast Asian background presents with complaints
of "wind overload" and dizziness, describing episodes where they feel weak and believe
wind is attacking their body. The PMHNP recognizes this as a cultural explanation of
distress. Which cultural concept of distress best describes this presentation?
A. Ataque de nervios
B. Dhat syndrome
C. Khyâl cap [CORRECT]
D. Taijin kyofusho
Correct Answer: C
Rationale: For NRNP6635 midterm, remember that khyâl cap is a Cambodian cultural
syndrome involving wind attacks that cause dizziness and weakness, attributed to an
imbalance of wind in the body. When working with diverse populations, always use the
Cultural Formulation Interview to understand how patients conceptualize their
symptoms within their cultural framework.
,Q2: During a psychiatric evaluation, the PMHNP notes that a patient frequently pauses
mid-sentence, loses their train of thought, and then resumes talking about a completely
unrelated topic. Which thought process best describes this pattern?
A. Tangentiality
B. Circumstantiality
C. Loosening of associations [CORRECT]
D. Flight of ideas
Correct Answer: C
Rationale: That's right because according to DSM-5-TR criteria and MSE documentation,
loosening of associations involves a breakdown in the logical connections between
thoughts, where the patient shifts from one topic to another with no apparent link.
Tangentiality eventually gets back to the point, circumstantiality includes excessive
detail but maintains connection, and flight of ideas has rapid but connected
topics—loosening of associations is the most disconnected.
Q3: A patient presents with their first episode of psychosis at age 68. No prior
psychiatric history exists. Which medical workup is most essential as part of the initial
evaluation?
A. Comprehensive metabolic panel only
B. Brain MRI, thyroid function tests, vitamin B12 level, urinalysis for substances, and
complete blood count [CORRECT]
C. Lumbar puncture and EEG only
,D. Genetic testing for Huntington's disease
Correct Answer: B
Rationale: When ruling out medical causes, always check for organic etiologies first in
late-onset psychosis—brain MRI rules out tumors or strokes, thyroid dysfunction can
cause psychosis, B12 deficiency is common in older adults, substance use must be
excluded, and CBC checks for infections or anemia. Late-onset psychosis is more likely
to have an underlying medical cause than early-onset schizophrenia.
Q4: The PMHNP is using the hypothetico-deductive model during a diagnostic interview.
Which step represents the core of this approach?
A. Memorizing all DSM-5-TR criteria before seeing the patient
B. Generating multiple hypotheses and testing them against collected data [CORRECT]
C. Relying solely on pattern recognition from previous cases
D. Using only screening tools to make the diagnosis
Correct Answer: B
Rationale: The hypothetico-deductive model is the backbone of clinical diagnostic
reasoning—you generate early hypotheses based on initial cues, then systematically
gather data to confirm or rule out each possibility. For NRNP6635 midterm, remember
this differs from pure pattern recognition, which relies on matching to familiar illness
scripts without active hypothesis testing.
, Q5: A patient reports hearing voices that comment on their actions and argue with each
other. The patient also believes their thoughts are being broadcast to others. Which
combination of symptoms represents Kurt Schneider's first-rank symptoms?
A. Auditory hallucinations and persecutory delusions
B. Voices commenting, voices arguing, and thought broadcasting [CORRECT]
C. Visual hallucinations and grandiose delusions
D. Somatic passivity and olfactory hallucinations
Correct Answer: B
Rationale: Schneider's first-rank symptoms specifically include voices arguing, voices
commenting on actions, and thought withdrawal/insertion/broadcasting—these were
historically considered highly suggestive of schizophrenia. While we now know these
symptoms can occur in other disorders, recognizing them remains important for
differential diagnosis on the midterm.
Q6: During a mental status exam, the PMHNP observes a patient who maintains
minimal eye contact, shows no emotional response to discussing their recent job loss,
and sits motionless throughout the interview. Which affect description is most
accurate?
A. Labile affect
B. Blunted affect
C. Flat affect [CORRECT]
D. Restricted affect
