Question 1: A patient reports a two-week history of progressive right-sided ptosis,
miosis, and anhidrosis. Which additional finding would most strongly localize the
lesion to the brainstem rather than the periphery?
A. Ipsilateral loss of taste over the anterior two-thirds of the tongue
B. Contralateral loss of pain and temperature sensation
C. Ipsilateral facial nerve palsy
D. Contralateral homonymous hemianopsia
Answer: B - Contralateral loss of pain and temperature sensation
Rationale: Horner syndrome with contralateral pain/temperature loss indicates a
brainstem (Wallenberg) lesion involving the lateral medulla, crossing spinothalamic
fibers. Peripheral lesions produce only ipsilateral sympathetic deficits.
Question 2: A 52-year-old patient presents with acute onset of severe pain and
swelling in the left knee. Arthrocentesis reveals cloudy synovial fluid with a WBC
count of 60,000/mm³ and 90% neutrophils. Which finding would most strongly
suggest septic arthritis over gout?
A. Presence of monosodium urate crystals
B. Serum uric acid level of 9.2 mg/dL
C. Positive synovial fluid Gram stain
D. History of recurrent monoarticular attacks
,Answer: C - Positive synovial fluid Gram stain
Rationale: A positive Gram stain is highly specific for bacterial septic arthritis. Urate
crystals confirm gout, and a history of recurrent attacks favors gout.
Question 3: A patient presents with transient monocular vision loss (amaurosis
fugax). What is the most appropriate next step in management?
A. Immediate ophthalmology referral
B. Prescribe topical beta-blocker and follow up in 1 week
C. Carotid duplex ultrasound and echocardiogram
D. Start high-dose corticosteroids
Answer: C - Carotid duplex ultrasound and echocardiogram
Rationale: Transient monocular vision loss is a TIA equivalent requiring urgent
evaluation for embolic sources, including carotid stenosis and cardiac embolism.
Topical beta-blockers are for glaucoma, not TIA.
Question 4: A patient with suspected carpal tunnel syndrome has a positive Phalen
test and thenar atrophy. Which electrodiagnostic finding would best confirm median
neuropathy at the wrist?
A. Prolonged distal latency of the median sensory nerve across the wrist
B. Reduced amplitude of the ulnar sensory nerve
C. Conduction block in the median nerve at the elbow
D. Fibrillation potentials in the first dorsal interosseous
Answer: A - Prolonged distal latency of the median sensory nerve across the wrist
Rationale: Carpal tunnel syndrome is confirmed by prolonged median sensory or motor
distal latency across the wrist. Ulnar abnormalities suggest a different nerve.
Question 5: Which of the following cranial nerve findings is most consistent with a
lesion at the cerebellopontine angle?
A. Ipsilateral facial numbness and hearing loss
B. Contralateral hemiparesis and aphasia
C. Bitemporal hemianopsia
D. Ipsilateral tongue deviation
,Answer: A - Ipsilateral facial numbness and hearing loss
Rationale: Cerebellopontine angle lesions (e.g., acoustic neuroma) typically compress
CN VII and VIII, causing ipsilateral hearing loss, tinnitus, and facial sensory changes.
Question 6: Which of the following best distinguishes a UMN lesion from an LMN
lesion on physical exam?
A. LMN lesions produce hyperreflexia and spasticity
B. UMN lesions produce fasciculations and atrophy
C. UMN lesions produce hyperreflexia and Babinski sign
D. LMN lesions produce clonus and Hoffman sign
Answer: C - UMN lesions produce hyperreflexia and Babinski sign
Rationale: UMN lesions are characterized by hyperreflexia, spasticity, and a positive
Babinski sign. LMN lesions cause hyporeflexia, atrophy, and fasciculations.
Question 7: A patient with a chronic condition presents with new-onset fatigue,
weight gain, and cold intolerance. Which pathophysiologic mechanism best explains
these findings?
A. Decreased metabolic rate due to thyroid hormone deficiency
B. Increased sympathetic nervous system activity
C. Excessive cortisol production leading to catabolism
D. Insulin resistance causing hyperglycemia
Answer: A - Decreased metabolic rate due to thyroid hormone deficiency
Rationale: Thyroid hormone deficiency (hypothyroidism) reduces basal metabolic rate,
causing fatigue, weight gain, and cold intolerance.
Question 8: A patient reports a sudden onset of severe, sharp chest pain that
radiates to the back, with a blood pressure differential of 20 mm Hg between arms.
Which diagnostic test is most definitive?
A. Transthoracic echocardiogram
B. Contrast-enhanced CT angiography
C. 12-lead ECG
D. D-dimer assay
, Answer: B - Contrast-enhanced CT angiography
Rationale: The presentation suggests aortic dissection. Contrast-enhanced CT
angiography is the gold standard for diagnosis, visualizing the intimal flap and false
lumen.
Question 9: Which of the following best describes the mechanism of action of SGLT2
inhibitors in reducing cardiovascular mortality in heart failure?
A. Inhibition of sodium-glucose cotransport in the proximal tubule, promoting
natriuresis and reducing preload
B. Blockade of angiotensin II receptors, decreasing afterload
C. Beta-adrenergic blockade, reducing heart rate and myocardial oxygen demand
D. Inhibition of neprilysin, increasing natriuretic peptides
Answer: A - Inhibition of sodium-glucose cotransport in the proximal tubule, promoting
natriuresis and reducing preload
Rationale: SGLT2 inhibitors reduce glucose and sodium reabsorption in the proximal
tubule, leading to natriuresis, reduced preload, and improved cardiac function.
Question 10: A patient with suspected meningitis undergoes a lumbar puncture. The
CSF shows elevated opening pressure, neutrophil predominance, low glucose, and
high protein. Which pathogen is most likely?
A. Streptococcus pneumoniae
B. Cryptococcus neoformans
C. Herpes simplex virus
D. Escherichia coli
Answer: A - Streptococcus pneumoniae
Rationale: Neutrophil predominance, low glucose, and high protein in CSF are classic
for bacterial meningitis, with Streptococcus pneumoniae being the most common cause
in adults.
Question 11: A patient with hyperglycemia presents with polyuria. Which mechanism
explains this finding?
A. Osmotic diuresis due to glucosuria
B. Increased ADH secretion
