100 Multiple Choice Questions with Answers and Rationales
1. Before prescribing for depression, which history is especially important?
A. Past mania or hypomania
B. Shoe size
C. Hand dominance alone
D. Favorite color
Correct answer: A. Past mania or hypomania
Rationale: A history of elevated mood and increased energy may change the
diagnosis and treatment plan. Antidepressant selection should follow a full bipolar
assessment.
2. A patient has depressed mood, anhedonia, and four other depressive
symptoms for three weeks. What is needed next?
A. Assume normal bereavement excludes illness
B. Assess impairment, exclusions, and bipolar history
C. Ignore substance use
D. Diagnose solely from a screening score
Correct answer: B. Assess impairment, exclusions, and bipolar history
Rationale: Duration and symptom count support consideration of a major
depressive episode. Medical, substance-related, bipolar, and contextual factors still
require evaluation.
3. Eight days of elevated mood, markedly increased energy, and severe
impairment suggest which episode?
A. Normal enthusiasm
B. Specific phobia
C. Isolated insomnia
D. Mania
Correct answer: D. Mania
Rationale: Sustained activation with severe impairment supports mania when
diagnostic criteria and exclusions are met. Reduced sleep alone does not establish
this diagnosis.

A. Bipolar II disorder
B. Specific learning disorder
C. Delirium

,D. Bipolar I solely from depression
Correct answer: A. Bipolar II disorder

depression.

A. Medical, substance, medication, and psychiatric causes
B. Ignoring cognition
C. Assuming schizophrenia immediately
D. Using appearance alone
Correct answer: A. Medical, substance, medication, and psychiatric causes

information, and indicated testing help identify reversible illness and refine the
diagnosis.
6. Which experience is a hallucination?
A. An intrusive unwanted thought only
B. A deliberate lie
C. Hearing a voice without an external stimulus
D. A fixed false belief
Correct answer: C. Hearing a voice without an external stimulus

Distinguishing perception from belief helps characterize symptoms without
prematurely assigning a disorder.
7. Fluctuating attention and acute confusion suggest what?
A. Uncomplicated grief alone
B. Delirium requiring medical evaluation

D. Routine aging
Correct answer: B. Delirium requiring medical evaluation
Rationale: An acute fluctuating disturbance of attention suggests delirium.

primary psychiatric illness.

medical mimic?

, C. Myopia alone
D. Handedness

A. Exclude bipolar disorder
B. Determine medication dose automatically
C. Establish the diagnosis by itself
D. Prompt diagnostic assessment

A. Automatic attribution to anxiety
B. Immediate dismissal
C. Only a personality inventory

resemble panic. Urgent features require medical assessment before psychiatric
attribution.

A. Generalized anxiety disorder when criteria are met
B. One isolated panic attack
C. A hallucination
D. Delirium
Correct answer: A. Generalized anxiety disorder when criteria are met

symptoms and impairment. Duration and exclusions must be established before
diagnosing.
