Section 1: Foundations of Psychopathology & Diagnostic Reasoning
(12 questions)
Q1: A 34-year-old patient immigrated from rural Guatemala two years ago. During your
psychiatric interview, she describes episodes of "ataque de nervios" involving sudden
shaking, crying, and verbal outbursts triggered by family stress. She does not meet
criteria for panic disorder or PTSD. Using the DSM-5-TR Cultural Formulation Interview
(CFI), what is the most appropriate next step?
A. Reassure her that ataque de nervios is a form of panic disorder and prescribe an SSRI
B. Ask how her community understands these episodes and what supports they offer
C. Diagnose her with brief psychotic disorder due to the sudden verbal outbursts
D. Refer her immediately to a neurologist to rule out seizure disorder
Correct Answer: B
,Rationale: For the NRNP6635 midterm, remember that the CFI is designed to explore
how patients and their communities understand distress, not to override cultural idioms
with Western diagnoses. Ataque de nervios is a recognized cultural concept of distress
in DSM-5-TR, and the CFI framework specifically asks about cultural explanations and
coping supports. That's right because according to DSM-5-TR criteria, you always start
with curiosity about the patient's cultural context before jumping to biomedical labels.
Q2: During a mental status exam, you observe a patient who takes 45 seconds to
answer simple questions, speaks in monosyllables, and shows minimal facial
expression. Which MSE term best describes this presentation?
A. Flight of ideas
B. Pressured speech
C. Poverty of speech and blunted affect
D. Circumstantiality
Correct Answer: C
Rationale: The MSE term that best describes this is poverty of speech (alogia) and
blunted affect—both classic negative symptoms that you'll need to distinguish from
thought process disorders on the midterm. The patient isn't showing rapid speech or
tangential connections; instead, you're seeing a restriction in both the amount of speech
,and the range of emotional expression, which points toward schizophrenia spectrum or
severe depressive presentations.
Q3: A 29-year-old graduate student presents with 3 weeks of depressed mood,
insomnia, poor concentration, and fatigue. He mentions his mother had depression and
his twin brother has bipolar disorder. Which model best explains why he might develop a
mood disorder while his roommate—with similar academic stress—does not?
A. Purely biological determinism
B. The diathesis-stress model
C. The biomedical model exclusively
D. Learned helplessness theory alone
Correct Answer: B
Rationale: The correct framework here is the diathesis-stress model, and for the
NRNP6635 midterm, you'll see this concept applied repeatedly in vignettes. That's right
because according to DSM-5-TR and current psychopathology thinking, genetic
vulnerability (the diathesis—his family history) interacts with environmental stressors
(academic pressure) to trigger disorder onset, while his roommate lacks that genetic
loading.
, Q4: You are evaluating a patient with first-episode psychosis. Which medical workup is
considered essential before confirming a primary psychiatric diagnosis?
A. CBC, CMP, TSH, urine drug screen, and vitamin B12 only
B. Neuroimaging for every patient regardless of age or presentation
C. TSH, CBC, CMP, urine drug screen, and symptom-directed neuroimaging
D. Lumbar puncture as a routine first-line test
Correct Answer: C
Rationale: When ruling out medical causes, always check thyroid function, metabolic
panel, blood counts, and substance use—then add neuroimaging based on red flags like
age over 40, abnormal neurological exam, or atypical features. For the NRNP6635
midterm, remember that routine lumbar puncture or universal neuroimaging isn't
standard; you individualize based on the clinical picture.
Q5: A patient scores 14 on the PHQ-9. According to standard scoring interpretation, how
should this result be categorized?
A. Minimal depression
B. Mild depression
