Section 1: Foundations & Diagnostic Reasoning (15 Questions)
Q1: A 34-year-old patient presents for initial evaluation. During the mental status exam,
the patient provides excessive unnecessary detail when answering questions but
eventually returns to the original point after several minutes. Which thought process
best describes this finding?
A. Tangential thinking
B. Circumstantial thinking
C. Circumstantial thinking [CORRECT]
D. Flight of ideas
Rationale: For the NRNP6635 final exam – Grade A level, remember that circumstantial
thinking involves excessive detail but the patient eventually gets back to the point,
whereas tangential thinking never returns to the original topic. That's right because
according to DSM-5-TR and MSE standards, this distinction is a common final exam trap
– the key difference is whether the patient returns to the original question or drifts
completely off track.
Correct Answer: C
,Q2: A 19-year-old college student is brought to the emergency department by campus
security after being found wandering the library talking to himself. He reports that "the
government has implanted a chip in my brain to read my thoughts" and that he can hear
two voices arguing about whether he should be killed. He has no history of mood
episodes. Which symptom cluster represents Kurt Schneider's first-rank symptoms?
A. Persecutory delusions and visual hallucinations
B. Thought broadcasting, thought insertion, and voices arguing [CORRECT]
C. Grandiose delusions and olfactory hallucinations
D. Somatic passivity and mood-congruent delusions
Rationale: The correct answer is B because Schneider's first-rank symptoms specifically
include thought broadcasting, thought insertion, thought withdrawal, voices arguing,
voices commenting, delusional perception, somatic passivity, and made
impulses/acts/feelings. When ruling out medical causes in first-episode psychosis,
always check that these symptoms indicate schizophrenia spectrum rather than a
primary mood disorder, especially since this patient lacks any mood episode history.
Correct Answer: B
Q3: During a diagnostic interview, a PMHNP recognizes that she is gravitating toward a
depression diagnosis because the last three patients she saw all had major depressive
disorder. She consciously decides to generate alternative hypotheses and asks about
manic symptoms. Which cognitive bias was the PMHNP initially demonstrating, and
which debiasing strategy did she employ?
A. Anchoring bias; considering the opposite
,B. Availability bias; considering the opposite [CORRECT]
C. Confirmation bias; metacognition
D. Premature closure; structured decision tools
Rationale: For the NRNP6635 final exam – Grade A level, remember that availability bias
occurs when recent or memorable cases disproportionately influence current diagnostic
reasoning – those three depression cases were "available" in her memory. Considering
the opposite is the classic debiasing strategy where you deliberately argue against your
initial hypothesis. A common final exam trap is confusing availability bias (recent cases
influence you) with anchoring bias (fixating on initial information).
Correct Answer: B
Q4: A 42-year-old Vietnamese-American patient describes experiencing "khyâl cap" –
episodes of sudden dizziness, palpitations, and shortness of breath with a fear that
wind and blood are rising in the body and causing a fatal neck vessel rupture. The
patient does not have fixed delusional beliefs outside these episodes. Which approach
should the PMHNP take in the cultural formulation interview?
A. Diagnose delusional disorder, somatic subtype
B. Document as a cultural concept of distress and explore CFI domains [CORRECT]
C. Diagnose panic disorder with culturally modified symptoms
D. Prescribe antipsychotics to address the somatic delusions
Rationale: The correct approach is B because khyâl cap is a recognized cultural concept
of distress in Cambodian and Vietnamese communities, not a delusional disorder. For
the NRNP6635 final exam – Grade A level, remember that the Cultural Formulation
, Interview (CFI) helps distinguish culturally normative idioms of distress from
psychopathology – the key difference is that cultural syndromes are understood within
the patient's cultural context and lack the fixed, systematized quality of true delusions.
The CFI domains include cultural definition of the problem, cultural perceptions of cause
and coping, and cultural factors affecting past help-seeking.
Correct Answer: B
Q5: A PMHNP is conducting a suicide risk assessment on a 56-year-old patient who
states, "I think about death every day, but I would never do that to my family." The patient
reports these thoughts last about 10 minutes, occur twice daily, are somewhat
controllable by calling his sister, and are driven by feeling like a burden. He denies any
intent, plan, or preparatory acts. Using the C-SSRS, what is the appropriate risk
categorization and next step?
A. High risk; immediate hospitalization
B. Moderate risk; safety planning with means restriction [CORRECT]
C. Low risk; routine follow-up in 3 months
D. Severe risk; involuntary commitment
Rationale: For the NRNP6635 final exam – Grade A level, remember that this patient has
active suicidal ideation with some intensity (frequency, duration, controllability, reasons
identified) but NO intent, NO plan, and NO preparatory acts – plus he has identified
deterrents (family) and protective factors. That's right because according to C-SSRS
guidelines, this places him in moderate risk requiring safety planning with means
restriction (firearms removal, medication lockbox), support network activation, and
