Section I: Psychiatric Assessment & Differential Diagnosis (Questions 1–50)
1. A 34-year-old woman presents with a 6-month history of low mood, anergia,
hypersomnia, increased appetite with a 12-pound weight gain, and rejection
sensitivity. She reports feeling "paralyzed" when criticized. Which specifier best
characterizes her major depressive disorder?
A. Melancholic features
B. Atypical features
C. Psychotic features
D. Catatonic features
Correct Answer: B
Rationale: Atypical features of major depressive disorder include mood
reactivity, weight gain, hypersomnia, leaden paralysis, and a long-standing
pattern of interpersonal rejection sensitivity. These symptoms contrast with
melancholic features, which include early morning awakening, weight loss, and
psychomotor agitation. This presentation is a classic high-yield DSM-5-TR
distinction.
2. A 22-year-old college student is brought to the clinic by his roommate after 4
days of decreased need for sleep, rapid speech, grandiose plans to "start a billion-
dollar company," and spending his tuition money on luxury watches. He denies
any depressive episodes. What is the most likely diagnosis?
A. Bipolar II disorder
B. Major depressive disorder with mixed features
,C. Bipolar I disorder, current episode manic
D. Cyclothymic disorder
Correct Answer: C
Rationale: Bipolar I disorder requires at least one manic episode lasting ≥1
week or requiring hospitalization. The patient demonstrates elevated mood,
decreased need for sleep, pressured speech, grandiosity, and reckless spending—
hallmark manic symptoms. Bipolar II requires hypomania plus a major depressive
episode.
3. A PMHNP is conducting a mental status examination. The patient's speech is
fluent but jumps rapidly from one topic to another with only tangential
connections. The patient cannot return to the original point. This is best described
as:
A. Circumstantiality
B. Flight of ideas
C. Loosening of associations
D. Clang associations
Correct Answer: B
Rationale: Flight of ideas is characterized by rapid, continuous speech with
abrupt topic shifts, typically seen in mania. Circumstantiality involves over-
inclusion of detail but eventual return to the point. Loosening of associations
(derailment) is more characteristic of schizophrenia, where connections between
ideas are illogical.
4. Which of the following is a core feature that distinguishes schizophrenia from
schizoaffective disorder?
A. Presence of auditory hallucinations
B. Duration of illness greater than 6 months
C. Presence of mood episodes concurrent with psychotic symptoms
D. Functional decline in social or occupational settings
Correct Answer: C
, Rationale: Schizoaffective disorder requires that mood episodes co-occur
with psychotic symptoms for the majority of the illness duration, while
schizophrenia features psychotic symptoms that occur independently of mood
episodes. The duration criterion (>6 months) applies to schizophrenia, and
hallucinations/functional decline occur in both.
5. A 67-year-old man is brought by his daughter for evaluation of 8 months of
progressive memory loss, word-finding difficulty, and getting lost in familiar
neighborhoods. He has no history of stroke, head trauma, or psychiatric illness.
What is the most likely diagnosis?
A. Delirium
B. Major neurocognitive disorder due to Alzheimer's disease
C. Vascular dementia
D. Normal-pressure hydrocephalus
Correct Answer: B
Rationale: Alzheimer's disease is the most common cause of major
neurocognitive disorder, characterized by insidious onset and gradual progression
of memory impairment and language difficulties. Delirium has acute onset and
fluctuating course. Vascular dementia typically has stepwise decline with focal
neurological signs.
6. A PMHNP is evaluating a 9-year-old boy for ADHD. Which of the following is
required for diagnosis according to DSM-5-TR?
A. Symptoms must be present before age 7
B. Symptoms must be present in at least two settings
C. Symptoms must cause clinically significant impairment in social, academic, or
occupational functioning
D. Both B and C
Correct Answer: D
Rationale: DSM-5-TR requires that ADHD symptoms be present in two or
more settings (e.g., home, school) and cause clinically significant impairment. The
, onset criterion was changed from "before age 7" to "several symptoms present
before age 12."
7. A 28-year-old woman presents with 3 weeks of persistent depressed mood,
anhedonia, insomnia, fatigue, and passive suicidal ideation. She recently lost her
job. She has no prior psychiatric history. What is the most appropriate first-line
screening tool to quantify her depressive symptoms?
A. GAD-7
B. PHQ-9
C. MDQ
D. PCL-5
Correct Answer: B
Rationale: The PHQ-9 is the standard validated tool for quantifying
depressive symptom severity and monitoring treatment response. The GAD-7
screens for generalized anxiety, the MDQ screens for bipolar disorder, and the
PCL-5 screens for PTSD.
8. A 45-year-old man presents with excessive worry about multiple life domains
for the past 2 years. He reports muscle tension, restlessness, and difficulty
concentrating. He denies panic attacks. What is the most likely diagnosis?
A. Panic disorder
B. Social anxiety disorder
C. Generalized anxiety disorder
D. Illness anxiety disorder
Correct Answer: C
Rationale: Generalized anxiety disorder is characterized by excessive
anxiety and worry about multiple domains for at least 6 months, accompanied by
symptoms such as restlessness, muscle tension, and concentration difficulties.
Panic disorder involves recurrent unexpected panic attacks.
9. Which of the following is a negative symptom of schizophrenia?
A. Auditory hallucinations
B. Delusions of persecution
