HIGH-YIELD QUESTIONS WITH CORRECT ANSWERS–
GUARANTEED PASS
SECTION 1: ADVANCED ASSESSMENT, MSE, & DIAGNOSTIC THRESHOLDS
1. During the initial psychiatric interview, the provider defers a detailed inquiry into the patient's past
psychiatric hospitalizations and prior medication trials until after a thorough psychosocial and
developmental history is obtained. What is the primary clinical rationale for this sequencing?
A. To expedite the interview and prevent patient fatigue before discussing sensitive trauma history.
B. To satisfy insurance reimbursement requirements for a biopsychosocial model note.
C. To mitigate anchoring bias, ensuring the current presentation is not prematurely attributed to an
established chronic condition or personality structure.
D. To ensure the patient’s family history of genetic predisposition is documented prior to establishing
medical necessity.
Answer: C. To mitigate anchoring bias, ensuring the current presentation is not prematurely
attributed to an established chronic condition or personality structure.
Explanation: The assessment sequence is deliberate. Front-loading the history with a diagnosis of
"Schizophrenia" or "Borderline Personality Disorder" from past records can lead to diagnostic
overshadowing, causing the clinician to overlook new medical comorbidities, substance-induced changes,
or a shift in symptom acuity. A comprehensive baseline (social, developmental, medical) must be
established first to maintain differential diagnostic rigor.
2. A patient presents with a 2-year history of pervasive distrust, reluctance to confide in others, and
recurrent suspicions regarding a spouse's fidelity despite no evidence. During the Mental Status
Examination (MSE), which finding differentiates this presentation (Paranoid Personality Disorder)
from Delusional Disorder, Persecutory Type?
A. The patient becomes visibly agitated and scans the room for threats.
B. The patient states, "I know my wife is poisoning my coffee because it tastes strange, and she is part of
a larger plot to take my house."
C. The patient states, "I believe my wife might be unfaithful; I check her phone, but I know it’s possible
I’m overreacting. I just can't shake the worry."
D. The patient demonstrates a formal thought disorder with tangentiality and loose associations.
Answer: C. The patient states, "I believe my wife might be unfaithful... I know it's possible I'm
overreacting."
Explanation: The crucial distinction lies in the level of conviction and reality testing. Delusional Disorder
(B) involves a fixed, false belief held with absolute conviction. Personality disorders (C), specifically
Paranoid PD, exist on a spectrum of suspiciousness and hypervigilance rather than fixed delusion.
Patients with Paranoid PD retain the capacity for self-reflection (even if limited), recognizing their
,2
suspicion as potentially excessive ("I might be overreacting"), whereas a delusional patient cannot
entertain alternative explanations.
3. A 74-year-old retired professor scores a 28/30 on the Mini-Mental State Exam (MMSE), missing two
points on the 5-minute recall task (he remembered 1 of 3 words) but scored perfectly on orientation
and serial sevens. The Clock Drawing Test (CDT) reveals a perfectly drawn circle with numbers in
correct spatial orientation but the hands are set to 10:05 instead of the requested 11:10. What is the
most specific interpretation of this isolated Clock Drawing error?
A. Impaired executive function and planning consistent with early vascular dementia.
B. Visuospatial constructional apraxia pathognomonic for Alzheimer's disease.
C. Isolated retrieval memory deficit with preserved encoding and visuospatial ability.
D. Normal age-related cognitive decline requiring no further workup.
Answer: A. Impaired executive function and planning consistent with early vascular dementia.
*Explanation: A score of 28/30 on the MMSE is considered normal; however, the "mini-cog" and CDT are
more sensitive to executive dysfunction. Isolated recall failure (retrieval) can be benign or related to
frontal-subcortical dysfunction. The specific error of placing hands incorrectly despite a perfectly drawn
clock face (preserved construction) suggests a deficit in planning and conceptualization—a hallmark of
executive function mediated by the frontal lobe. Alzheimer's typically presents with constructional
apraxia (distorted circle/numbers) earlier. This discrepancy mandates ruling out small vessel ischemic
disease (vascular dementia).*
4. According to Gottesman et al. (2010), which familial genetic loading scenario confers the highest
empirical lifetime risk for developing Schizophrenia?
A. A dizygotic (fraternal) twin diagnosed with Schizophrenia.
B. A monozygotic (identical) twin diagnosed with Schizophrenia.
C. Both biological parents diagnosed with Schizophrenia.
D. One biological parent and one sibling diagnosed with Schizophrenia.
Answer: C. Both biological parents diagnosed with Schizophrenia.
*Explanation: While monozygotic twin concordance is high (approx. 40-50%), the cumulative genetic
liability of two affected first-degree parents (both mother and father) yields a combined risk of 27-
46% depending on the study cohort. This exceeds the risk for offspring with only one affected parent
(~7-13%). The question tests the distinction between shared environment (twin) vs. double-dose genetic
loading (dual parental lineage).*
5. A 68-year-old patient with a history of Stage 1 Hypertension (per JNC 7/8 guidelines) presents with
a thyroid panel showing TSH of 6.8 mIU/L (Ref: 0.4-4.2) and Free T4 of 1.1 ng/dL (Ref: 0.8-1.8). The
patient denies cold intolerance or weight gain. What is the most accurate interpretation and next
step?
A. Secondary Hypothyroidism; MRI of the pituitary is indicated due to inappropriately normal Free T4.
B. Subclinical Primary Hypothyroidism; repeat TSH in 6-12 weeks with TPO antibody testing.
C. Overt Primary Hypothyroidism; initiate Levothyroxine 1.6 mcg/kg/day immediately.
D. Euthyroid Sick Syndrome; no further workup needed given lack of symptoms.
Answer: B. Subclinical Primary Hypothyroidism; repeat TSH in 6-12 weeks with TPO antibody testing.
*Explanation: This is a classic presentation of Subclinical Hypothyroidism: Elevated TSH with Normal
,3
Free T4. Primary is indicated by the elevated TSH (thyroid gland failing, pituitary responding). Secondary
hypothyroidism (A) would present with Low or Normal TSH and Low T4. Treatment (C) is generally not
initiated until TSH > 10 mIU/L or in the presence of clear hypothyroid symptoms/goiter. Given the
psychiatric context, this lab finding must be corrected as it can mimic or exacerbate depression and
cognitive slowing.*
SECTION 2: NEUROLOGY & GENERAL MEDICAL SCREENING IN PSYCHIATRY
6. A patient on a stable dose of Lithium Carbonate 900mg QHS develops a coarse tremor, polyuria,
and new-onset diarrhea. Palpation of the neck reveals a palpable nodule > 1cm in the left
supraclavicular fossa. Which of the following is the most critical, non-negotiable diagnostic action?
A. Obtain an immediate STAT Lithium level to rule out toxicity.
B. Discontinue Lithium due to iatrogenic nephrogenic diabetes insipidus.
C. Perform an urgent ultrasound and biopsy referral for the supraclavicular lymph node.
D. Prescribe Propranolol 20mg BID for the Lithium-induced tremor.
Answer: C. Perform an urgent ultrasound and biopsy referral for the supraclavicular lymph node.
*Explanation: While Lithium toxicity (A) is in the differential for GI distress and tremor, the Sentinel
Node Finding overrides this. A lymph node >1cm in the supraclavicular fossa (Virchow's Node) is an
ominous sign often associated with intra-abdominal malignancy (gastric, pancreatic) or thoracic
malignancy. This is a "Red Flag" finding irrespective of the psychiatric presentation. Failure to act on this
physical exam finding constitutes malpractice. The Lithium tremor is typically fine (not coarse) and
relieved by beta-blockers, but C takes absolute priority.*
7. A patient presents with vertical diplopia when descending stairs and difficulty moving the eye
"down and in." Which cranial nerve (CN) is specifically implicated, and what is the most likely
mechanism if this occurs in isolation?
A. CN III (Oculomotor); Compressive lesion (aneurysm) of the posterior communicating artery.
B. CN IV (Trochlear); Microvascular ischemia secondary to diabetes mellitus.
C. CN VI (Abducens); Increased intracranial pressure causing false localizing sign.
D. CN III (Oculomotor); Demyelination of the medial longitudinal fasciculus.
Answer: B. CN IV (Trochlear); Microvascular ischemia secondary to diabetes mellitus.
Explanation: The Trochlear nerve (CN IV) innervates the Superior Oblique muscle. The primary action of
the superior oblique is Intorsion and Depression (especially in adduction). A hallmark of CN IV palsy is
difficulty reading or walking down stairs (vertical diplopia). In an older adult with vascular risk factors,
isolated CN IV palsy is most commonly due to microvascular infarction. CN III (A) presents with ptosis and
"down and out" eye deviation; CN VI (C) presents with horizontal diplopia.
8. A 45-year-old male with suspected HIV presents for an initial psychiatric consultation for apathy
and cognitive slowing. The ELISA returns positive; Western Blot confirms. His CD4 count is 190
cells/mm³. According to CDC staging, what is the appropriate classification, and what is the
implication for psychiatric differential diagnosis?
A. Stage 1 (HIV Infection); Rule out Adjustment Disorder.
B. Stage 2 (HIV Infection); Rule out Major Depressive Disorder.
, 4
C. Stage 3 (AIDS); Rule out HIV-Associated Neurocognitive Disorder (HAND) and opportunistic CNS
infections (Toxoplasmosis).
D. Latent Stage; Rule out Somatization Disorder.
Answer: C. Stage 3 (AIDS); Rule out HIV-Associated Neurocognitive Disorder (HAND) and
opportunistic CNS infections (Toxoplasmosis).
*Explanation: A CD4 count below 200 cells/mm³ (or the presence of an AIDS-defining illness)
defines Stage 3 (AIDS) regardless of viral load. Apathy and cognitive slowing in this context cannot be
assumed to be functional depression. The differential must prioritize organic etiology: HAND (HIV-
Associated Neurocognitive Disorder) , CNS Lymphoma, Progressive Multifocal Leukoencephalopathy
(PML), or Toxoplasmosis Gondii encephalitis.*
SECTION 3: PERSONALITY DISORDERS & COMPLEX TRAUMA
9. A 32-year-old patient presents with a history of multiple, brief hospitalizations for suicidal gestures
following perceived rejections. During the interview, the patient alternately idealizes the provider
("You're the only one who understands me") and devalues previous providers ("They were completely
incompetent and abusive"). Which defense mechanism is primarily being exhibited, and which
evidence-based psychotherapy specifically targets this phenomenon?
A. Projection; Cognitive Behavioral Therapy (CBT).
B. Splitting; Dialectical Behavior Therapy (DBT).
C. Reaction Formation; Mentalization-Based Treatment (MBT).
D. Dissociation; Prolonged Exposure Therapy (PE).
Answer: B. Splitting; Dialectical Behavior Therapy (DBT).
Explanation: The scenario depicts Borderline Personality Disorder. The oscillation between idealization
and devaluation is the hallmark defense mechanism of Splitting (the inability to integrate positive and
negative aspects of self and others into a cohesive whole). While multiple therapies are effective, DBT
(Dialectical Behavior Therapy) is the gold-standard, evidence-based treatment specifically designed to
target emotional dysregulation, interpersonal chaos, and splitting behaviors through skills training in
mindfulness and distress tolerance.
10. A patient with Obsessive-Compulsive Personality Disorder (OCPD) presents to the clinic with a
meticulously typed, 14-page document outlining their daily schedule in 5-minute increments. They
refuse to delegate tasks at work because "No one else meets my standards for formatting." Which of
the following features definitively rules out a comorbid diagnosis of Obsessive-Compulsive Disorder
(OCD) ?
A. The patient spends more than 1 hour per day on these organizing tasks.
B. The patient experiences significant anxiety if the schedule is disrupted.
C. The patient believes their meticulousness is a virtue and necessary for success (ego-syntonic).
D. The patient has a first-degree relative with a diagnosis of Hoarding Disorder.
Answer: C. The patient believes their meticulousness is a virtue and necessary for success (ego-
syntonic).
Explanation: This is the classic distinguishing feature. OCPD is Ego-Syntonic: the traits are consistent with
