Q1 Question 1 of 100
Correct | Grade A - Chamberlain 2026/2027 — 2026/2027 Official Exam 2026/2027
A 58-year-old woman presents to her primary care provider reporting persistent low mood,
weight gain, constipation, and fatigue over the past four months. She has no prior psychiatric
history but reports feeling sluggish and uninterested in her usual hobbies. Her family notes
she seems mentally slower than usual. On physical examination, her skin is dry and her
reflexes show delayed relaxation.
A. Major depressive disorder with atypical features, given the prominent anhedonia and weight
gain that warrant initiation of an SSRI
B. Hypothyroidism, as the constellation of constitutional and neuropsychiatric symptoms strongly
suggests an endocrine etiology requiring TSH testing
C. Adjustment disorder with depressed mood, since her symptoms developed insidiously without
an identifiable stressor to explain the clinical picture
D. Persistent depressive disorder (dysthymia), considering the subthreshold intensity of her mood
symptoms over this extended four-month timeframe
Correct Answer: B
Rationale:
This presentation is classic for hypothyroidism, which frequently mimics depression with fatigue, weight gain, constipation,
cognitive slowing, and dry skin. Major depressive disorder (A) cannot be confirmed until medical causes are ruled out, and
starting an SSRI before checking TSH would be premature.

, Q2 Question 2 of 100
A 22-year-old college student is brought to the emergency department by his roommate after
he was found talking to himself and refusing to leave his dorm room for three days. He
reports hearing his professors' voices commenting on his thoughts. His urine drug screen is
positive for cocaine metabolites. He has no prior psychiatric history and his family reports he
was functioning normally two weeks ago.
A. Schizophrenia, because auditory hallucinations and social withdrawal are hallmark first-episode
psychotic symptoms requiring long-term antipsychotic therapy
B. Schizoaffective disorder, given the combination of psychotic symptoms and possible mood
instability related to his academic stressors this semester
C. Substance-induced psychotic disorder, since the temporal relationship to recent cocaine use
and lack of prior psychiatric history point to a drug-related etiology
D. Brief psychotic disorder, because the acute onset and short duration of symptoms fit the criteria
even without an identifiable precipitating stressor
Correct Answer: C
Rationale:
The positive urine drug screen for cocaine metabolites, acute onset, and absence of prior psychiatric history strongly
suggest substance-induced psychotic disorder. Schizophrenia (A) requires ruling out substance effects and typically has a
more insidious onset with longer duration of symptoms.
Q3 Question 3 of 100
A 9-year-old boy is referred by his teacher for evaluation due to frequent fidgeting, difficulty
remaining seated during class, and interrupting other students. However, his parents report
that at home he can focus intently on building Lego sets for over an hour. His grades are
average, and he does not display impulsivity when playing one-on-one with his father. There
is no family history of ADHD.
A. Attention-deficit/hyperactivity disorder, combined presentation, as his classroom behaviors
meet the DSM-5-TR threshold for both inattention and hyperactivity
B. Oppositional defiant disorder, because his disruptive classroom behavior represents a willful
refusal to follow rules rather than an attentional deficit
C. Situational inattention related to classroom environment demands, given that sustained focus is
preserved in preferred activities at home
D. Autism spectrum disorder, considering his restricted interest in Lego building and social
difficulties in the structured school setting
Correct Answer: C
Rationale:
The ability to sustain attention during preferred activities (Lego building, one-on-one play) argues against a pervasive
neurodevelopmental disorder like ADHD. ADHD (A) requires symptoms present in at least two settings, and his functioning
at home is notably intact.

, Q4 Question 4 of 100
A 31-year-old woman presents with a 12-year history of intense, unstable relationships,
chronic feelings of emptiness, and recurrent self-harm through wrist cutting. She describes
frequent episodes of dissociation when stressed and a persistent fear of abandonment. She
works as an office manager and has never had a manic or psychotic episode. Her mood
shifts dramatically within hours rather than days.
A. Bipolar II disorder, because her rapid mood swings and impulsive self-harm behavior reflect
underlying hypomanic and depressive cycling
B. Post-traumatic stress disorder, given that self-harm, dissociation, and fear of abandonment are
classic sequelae of early interpersonal trauma
C. Major depressive disorder with borderline features, since chronic emptiness and self-injury
commonly co-occur with treatment-resistant depression
D. Borderline personality disorder, as the pattern of instability in relationships, affect, and
self-image along with self-harm is characteristic of this condition
Correct Answer: D
Rationale:
The longstanding pattern of interpersonal instability, affective dysregulation, identity disturbance, and recurrent self-harm is
prototypical of borderline personality disorder. Bipolar II (A) is less likely because her mood shifts occur within hours rather
than meeting the duration criteria for hypomanic or depressive episodes.
Q5 Question 5 of 100
A 44-year-old man sees his nurse practitioner complaining of chest pain, palpitations, and
shortness of breath that have occurred episodically over the past six weeks. He has visited
the emergency department twice, and both times cardiac workups were negative. He now
avoids driving alone and has started working from home. He describes a constant dread that
something is physically wrong despite reassurance from his cardiologist.
A. Panic disorder, as the recurrent episodes of somatic symptoms with catastrophic health fears
and subsequent avoidance behavior are diagnostic hallmarks
B. Somatic symptom disorder, given his persistent physical complaints and excessive
health-related anxiety despite normal cardiac evaluations
C. Illness anxiety disorder, because his primary focus is on the fear of having a serious disease
rather than on the somatic symptoms themselves
D. Generalized anxiety disorder, since his constant dread and functional impairment across
multiple domains indicate pervasive and uncontrollable worry
Correct Answer: A
Rationale:
Recurrent discrete episodes of intense somatic symptoms (chest pain, palpitations) with catastrophic fear, negative medical
workups, and behavioral avoidance (not driving, working from home) are classic for panic disorder. Somatic symptom
disorder (B) typically involves more persistent somatic complaints rather than episodic attacks.
