Question 1
A 55-year-old man with type 2 diabetes mellitus presents with
severe right foot pain that started suddenly overnight after a
steak dinner. Physical examination shows swelling, redness,
and tenderness of the first metatarsophalangeal joint. Joint
aspiration reveals monosodium urate crystals. What is the
best initial treatment?
A. Allopurinol
B. Colchicine
C. Non-steroidal anti-inflammatory drugs (NSAIDs)
D. Probenecid
Correct Answer: C. Non-steroidal anti-inflammatory drugs
(NSAIDs)
Rationale: NSAIDs are first-line treatment for acute gouty
,arthritis. They inhibit cyclooxygenase enzymes, decreasing
prostaglandin synthesis and providing broad anti-inflammatory
effects. Uric acid-lowering therapy (allopurinol, probenecid)
should NOT be initiated during an acute attack as it can
exacerbate symptoms. Colchicine is an alternative but has a
narrow therapeutic window .
Question 2
A 50-year-old man presents with excessive daytime
sleepiness, falling asleep at his desk and while watching
television. He sleeps 8 hours per night. His BMI is 38 kg/m²
and blood pressure is 160/100 mm Hg. What is the best next
step in management?
A. Ambulatory ECG monitoring
B. CT scan of the head
C. Nocturnal polysomnography
D. Sleep hygiene education
Correct Answer: C. Nocturnal polysomnography
Rationale: This patient has signs of obstructive sleep apnea
(OSA): obesity, resistant hypertension, and hypersomnolence
despite adequate sleep time. OSA results from pharyngeal
muscle laxity causing upper airway obstruction during sleep,
leading to frequent arousals and poor sleep quality.
,Polysomnography (sleep study) is the gold standard for
diagnosis. Sleep hygiene education is inadequate when the
issue is sleep quality rather than quantity .
Question 3
A 45-year-old man has many pigmented lesions on his back,
including a single, flat, dark, 9-mm lesion with irregular
borders. What is the best next step?
A. Excisional biopsy
B. Incisional biopsy
C. Photographic documentation and comparison in 6-12 months
D. Reassurance and routine follow-up
Correct Answer: A. Excisional biopsy
Rationale: Features suspicious for melanoma include size ≥6
mm, border irregularity, asymmetry, and color variation. Early
diagnosis is critical due to melanoma's aggressive nature and
high metastatic potential. Excisional biopsy with a 1- to 3-mm
margin is the preferred method to determine lesion
thickness—the most important prognostic factor. Incisional
biopsy is not recommended as it does not allow for accurate
thickness measurement .
, Question 4
A 21-year-old woman has urinary frequency and urgency for 2
days with scant vaginal discharge. Urinalysis shows
bacteriuria, pyuria, and microscopic hematuria. Which
additional finding would most suggest pyelonephritis rather
than cystitis?
A. Bacteriuria
B. Leukocytosis
C. Microscopic hematuria
D. White blood cell casts
Correct Answer: D. White blood cell casts
Rationale: WBC casts are formed only in renal tubules, making
them specific for intrarenal pathology like pyelonephritis.
Both upper and lower UTIs can show hematuria, pyuria, and
bacteriuria. Leukocytosis is a nonspecific sign of systemic
inflammation. The presence of WBC casts confirms
pyelonephritis .
Question 5
A 50-year-old man presents with sudden severe headache,
nausea, and left eye pain. He has a mild cold and took an oral
decongestant this morning. Examination shows a nonreactive,
