Which symptom must be present for a diagnosis of schizophrenia?
A. Depression
B. Anxiety
C. Delusions, hallucinations, or disorganized speech
D. Memory loss
Correct Answer: C
Rationale: DSM-5-TR requires at least two core symptoms for at least 1 month,
and one must be delusions, hallucinations, or disorganized speech. These are
considered active-phase psychotic symptoms. Negative symptoms alone are
insufficient for diagnosis without at least one positive symptom.*

Which condition is most associated with rapid cycling bipolar disorder?
A. Lithium toxicity
B. Hypothyroidism
C. Hyperthyroidism
D. Low sodium intake
Correct Answer: B
Rationale: Hypothyroidism has been associated with rapid cycling bipolar disorder
(four or more mood episodes per year). Thyroid dysfunction should be screened in
patients with frequent mood cycling, and correction may improve mood stability.*
Which medication is preferred for treating agitation in dementia?
A. Benzodiazepines first-line
B. Low-dose atypical antipsychotic (if severe and dangerous)
C. High-dose haloperidol
D. Lithium
Correct Answer: B

risk, low-dose atypical antipsychotics may be cautiously used, recognizing black
box warnings for increased mortality in elderly patients with dementia-related
psychosis.*
