agitation for 3 months. Which is the most likely diagnosis?
• A) Bipolar I Disorder
• B) Major Depressive Disorder
• C) Persistent Depressive Disorder (Dysthymia)
• D) Adjustment Disorder
Answer: C
Rationale: Dysthymia (Persistent Depressive Disorder) is characterized by
depressed mood for at least 2 years in adults, with no periods of hypomania. The
patient's symptoms of low mood, fatigue, and agitation for 3 months suggest a
chronic depressive disorder.

hallucinations and delusions?
• A) Decreased serotonin
• B) Increased dopamine (mesolimbic pathway)
• C) Increased GABA
• D) Decreased norepinephrine
Answer: B
Rationale: Hyperactivity of dopamine in the mesolimbic pathway is associated
with positive symptoms of schizophrenia, including hallucinations and delusions.
This is the basis for the dopamine hypothesis of schizophrenia.

harm themselves. What is the highest-priority intervention?
• A) Increase antipsychotic dose
• B) Initiate safety assessment and protective measures
• C) Encourage journaling of thoughts
• D) Schedule group therapy
Answer: B
Rationale: Safety always comes first. Command hallucinations to self-harm
indicate imminent risk. The immediate priority is to assess the patient's safety,
conduct a suicide risk assessment, and implement protective measures.

• A) Antidepressants
• B) Stimulants
• C) Antipsychotics
• D) Benzodiazepines

inducing mania. It is FDA-approved for maintenance treatment of bipolar disorder
and is often used for depressive episodes.

regularly?
• A) ALT/AST
, • B) White blood cell count (WBC)
• C) Serum calcium
• D) Lipid panel
Answer: B
Rationale: Clozapine can cause agranulocytosis, a life-threatening drop in white
blood cell count. Routine WBC monitoring is mandatory through the REMS (Risk
Evaluation and Mitigation Strategy) program.
8. Which symptom is characteristic of Premenstrual Dysphoric Disorder
(PMDD)?
