COMPLETE 400 REAL EXAM QUESTIONS AND
CORRECT VERIFIED ANSWERS/ ALREADY
GRADED A+ (MOST RECENT!!)
1. A patient with obsessive-compulsive disorder has not responded to adequate trials of
SSRIs and clomipramine. Which evidence-based psychotherapy augmentation is most
appropriate?
A. Dialectical behavior therapy
B. Eye movement desensitization and reprocessing
C. Exposure and response prevention
D. Cognitive behavioral analysis system of psychotherapy
Answer: C
Rationale: Exposure and response prevention (ERP) is first-line behavioral therapy for OCD,
directly targeting compulsive rituals. DBT is for emotion dysregulation, EMDR for trauma, and
CBASP for chronic depression.
2. A patient presents with complaints of memory lapses. Cognitive screening reveals a score
of 24/30 on the Montreal Cognitive Assessment. Which domain is most likely impaired?
A. Orientation
B. Visuospatial/executive
C. Registration
D. Recall
Answer: B
Rationale: The MoCA emphasizes visuospatial/executive function and is more sensitive to mild
cognitive impairment than the MMSE. A score of 24 suggests deficits in executive domains
rather than orientation or simple registration.

,3. A patient with mood instability, impulsivity, and recurrent suicidal gestures has been
diagnosed with bipolar II disorder but has not responded to mood stabilizers. Which
finding most strongly suggests borderline personality disorder instead?
A. Grandiose delusions during manic episodes
B. Chronic feelings of emptiness
C. Racing thoughts and decreased need for sleep
D. History of hypomanic episodes lasting 4 days
Answer: B
Rationale: Chronic emptiness is a core diagnostic criterion for borderline personality disorder
and is not typical of bipolar II. Grandiosity, racing thoughts, and decreased sleep are more
characteristic of hypomania.
4. A psychiatrist recommends electroconvulsive therapy for a patient with severe
depression who initially refused but now appears confused and states, 'I don't remember
anything about that.' Which ethical principle is most directly challenged?
A. Autonomy
B. Beneficence
C. Nonmaleficence
D. Justice
Answer: A
Rationale: Autonomy requires informed consent based on understanding. The patient's confusion
and lack of memory undermine their capacity to consent, directly challenging respect for their
autonomy.
5. A patient with schizophrenia develops significant weight gain and hyperglycemia on
olanzapine. Which antipsychotic switch is best to minimize metabolic side effects?
A. Clozapine
B. Quetiapine
C. Aripiprazole
D. Risperidone
Answer: C
Rationale: Aripiprazole has a lower metabolic risk profile as a partial agonist. Clozapine and
quetiapine also cause significant weight gain and dyslipidemia; risperidone has intermediate
risk.
6. A patient presents with confusion, tachycardia, hypertension, hyperthermia, and clonus.
They take an SSRI and recently started a triptan for migraines. Which condition is most
likely?
A. Neuroleptic malignant syndrome
B. Serotonin syndrome
Page 2
,C. Anticholinergic delirium
D. Malignant hyperthermia
Answer: B
Rationale: Serotonin syndrome results from serotonergic excess, here from SSRI plus triptan
(5-HT1B/1D agonist). Clonus differentiates it from NMS (rigidity, bradykinesia), and history
distinguishes from anticholinergic delirium and malignant hyperthermia.
7. A patient with treatment-resistant depression is being considered for esketamine
therapy. Which neurobiological mechanism is primarily targeted?
A. Dopamine D2 antagonism
B. Norepinephrine reuptake inhibition
C. NMDA glutamate receptor antagonism
D. GABA-A receptor potentiation
Answer: C
Rationale: Esketamine is an NMDA receptor antagonist that increases glutamatergic signaling,
promoting synaptogenesis and rapid antidepressant effects.
8. A patient from Puerto Rico describes episodes of shaking, heart palpitations, and a
feeling of losing control, attributed to 'ataque de nervios.' These symptoms are not better
explained by panic disorder. Which cultural syndrome is most relevant?
A. Dhat syndrome
B. Khyâl cap
C. Ataque de nervios
D. Shenjing shuairuo
Answer: C
Rationale: Ataque de nervios is a culture-bound syndrome common in Latinx populations,
featuring shaking, palpitations, and a sense of being out of control. Dhat syndrome involves
semen-loss anxiety, Khyâl cap is a Vietnamese wind attack, and Shenjing shuairuo is
neurasthenia.
9. An older adult with major depressive disorder and mild cognitive impairment has not
responded to two adequate trials of SSRIs. Which treatment approach is most
appropriate?
A. Start a tricyclic antidepressant
B. Augment with methylphenidate
C. Refer for electroconvulsive therapy
D. Increase SSRI dose beyond maximum
Answer: B
Rationale: Methylphenidate augmentation can improve energy and cognition in geriatric
depression with cognitive impairment. TCAs have anticholinergic risks; ECT is invasive;
exceeding maximum SSRI dose is not recommended due to side effect risks.

, 10. A patient with schizophrenia has prominent negative symptoms and experiences
extrapyramidal side effects on haloperidol. Which atypical antipsychotic's receptor profile
suggests it may best address negative symptoms while minimizing EPS?
A. Clozapine
B. Risperidone
C. Aripiprazole
D. Olanzapine
Answer: A
Rationale: Clozapine has high affinity for D4 and 5-HT2A receptors with relatively weak D2
blockade, reducing EPS. It is uniquely effective for treatment-resistant and negative symptoms.
Risperidone and aripiprazole can cause EPS at higher doses; olanzapine has metabolic risks but
does not surpass clozapine for negative symptoms.
11. A patient with recurrent self-harm and emotional instability shows minimal response to
CBT. Which therapeutic approach emphasizes dialectical strategies and mindfulness to
reduce impulsive behaviors?
A. Cognitive behavioral therapy
B. Dialectical behavior therapy
C. Acceptance and commitment therapy
D. Psychodynamic therapy
Answer: B
Rationale: DBT combines CBT with mindfulness and distress tolerance, specifically targeting
self-harm and emotional dysregulation common in borderline personality disorder. ACT focuses
on acceptance, psychodynamic therapy on unconscious conflicts. CBT alone may not provide the
necessary skills training for this presentation.
12. A patient presents with multiple episodes of hypomania and major depression over two
years, meeting full criteria for a hypomanic episode lasting 4-5 days. According to DSM-5,
which diagnosis best fits?
A. Bipolar II disorder
B. Cyclothymic disorder
C. Bipolar I disorder
D. Other specified bipolar disorder
Answer: A
Rationale: Bipolar II requires at least one hypomanic episode ("e4 days) and one major
depressive episode. Cyclothymic disorder involves numerous hypomanic and depressive
symptoms not meeting full criteria for episodes over 2 years. Bipolar I requires mania. The
given duration and severity meet bipolar II criteria.
