question:1. "A 45-year-old man presents with sudden onset severe chest pain radiating to the
back. His blood pressure is 180/100 mmHg in the right arm and 140/80 mmHg in the left arm.
CT angiography shows an intimal flap in the ascending aorta. Which of the following is the most
appropriate next step in management?",
"A. Immediate surgical repair",
"B. Intravenous thrombolytics",
"C. Oral beta-blocker therapy",
"D. Percutaneous coronary intervention",
"E. Anticoagulation with heparin"
],
correct: "A",
rationale: "This presentation is classic for Stanford Type A aortic dissection (involving the
ascending aorta). The differential blood pressure between arms, tearing chest pain radiating to
the back, and CT showing an intimal flap in the ascending aorta confirm this diagnosis. Type A
dissections are surgical emergencies because of the risk of aortic rupture, cardiac tamponade,
and coronary artery occlusion. Immediate surgical repair is the definitive treatment.
,Thrombolytics are contraindicated as they worsen bleeding. Beta-blockers are used in Type B
dissections medically. PCI is for coronary artery disease. Anticoagulation increases hemorrhagic
risk."
question:2. "A 28-year-old woman at 32 weeks gestation presents with headache, visual
disturbances, and a blood pressure of 158/105 mmHg on two readings 6 hours apart. Urinalysis
shows 3+ proteinuria. Fetal heart tracing is reassuring. Which of the following is the most
appropriate management?",
"A. Immediate cesarean delivery",
"B. Induction of labor at 34 weeks",
"C. Expectant management with antihypertensives and corticosteroids",
"D. Oral labetalol and discharge home",
"E. MRI of the brain to rule out cerebral hemorrhage"
],
correct: "C",
rationale: "This patient has severe features of preeclampsia (BP ≥160/110 on two occasions
OR symptoms like headache/visual disturbances with BP ≥140/90) at 32 weeks. Between 24–34
weeks with severe features and stable maternal and fetal condition, expectant management is
appropriate. This includes antihypertensive therapy (IV labetalol or hydralazine for acute
control), corticosteroids (betamethasone) for fetal lung maturity, magnesium sulfate for seizure
prophylaxis, and close monitoring. Immediate delivery is indicated if maternal or fetal condition
deteriorates. Induction at 34 weeks would be appropriate if expectant management is chosen
and the patient reaches 34 weeks."
question:3. "A 65-year-old man with a 40 pack-year smoking history presents with a 3-cm
spiculated lung mass on CT scan. PET scan shows hypermetabolic activity in the mass and
ipsilateral mediastinal lymph nodes (N2 disease). Biopsy reveals non-small cell lung carcinoma.
What is his clinical stage?",
"A. Stage IA",
"B. Stage IIB",
, "C. Stage IIIA",
"D. Stage IIIB",
"E. Stage IV"
],
correct: "C",
rationale: "Using the TNM staging system for NSCLC: T2a (3 cm tumor), N2 (ipsilateral
mediastinal or subcarinal lymph node involvement), M0 (no distant metastases). T2a N2 M0
corresponds to Stage IIIA. Stage IIIA NSCLC is locally advanced and is generally treated with
concurrent chemoradiation (typically cisplatin/etoposide with radiation) rather than surgical
resection alone, though surgery may be considered in select cases after neoadjuvant therapy.
N2 disease specifically refers to ipsilateral mediastinal or subcarinal lymph nodes, which
differentiates Stage IIIA from Stage IIIB (contralateral mediastinal nodes, N3)."
question:4. "A 4-year-old boy is brought in by his mother for evaluation of a limp. She noticed
he started limping 2 weeks ago but denies any trauma or fever. Examination reveals limited
internal rotation of the left hip. X-ray shows flattening and sclerosis of the left femoral head.
What is the most likely diagnosis?",
"A. Septic arthritis",
"B. Transient synovitis",
"C. Legg-Calvé-Perthes disease",
"D. Developmental dysplasia of the hip",
"E. Slipped capital femoral epiphysis"
],
correct: "C",
rationale: "Legg-Calvé-Perthes (LCP) disease is avascular necrosis of the femoral head in
children, most commonly affecting boys aged 4–8 years. The hallmark findings are: painless or
mildly painful limp, limited hip range of motion (especially internal rotation and abduction), and
X-ray showing femoral head flattening, sclerosis, and fragmentation. Septic arthritis presents
acutely with fever and severe pain. Transient synovitis resolves within weeks and X-ray is
, normal. DDH presents in infancy. SCFE occurs in adolescents (10–16 years) and shows a
posterior-inferior slip of the femoral epiphysis ('ice cream falling off cone' appearance)."
question:5. "A 55-year-old woman with type 2 diabetes and CKD stage 3 (eGFR 38 mL/min)
presents for cardiovascular risk reduction. Her HbA1c is 8.2%. Which antidiabetic medication
would provide both glycemic control and cardiovascular/renal benefit in this patient?",
"A. Metformin",
"B. Glipizide",
"C. Empagliflozin",
"D. Pioglitazone",
"E. Sitagliptin"
correct: "C",
rationale: "SGLT-2 inhibitors (empagliflozin, canagliflozin, dapagliflozin) have demonstrated
both cardiovascular and renoprotective benefits in large clinical trials (EMPA-REG OUTCOME,
CREDENCE, DAPA-CKD). In patients with T2DM and established CKD or cardiovascular disease,
SGLT-2 inhibitors are recommended as second-line agents. Metformin is contraindicated when
eGFR <30 and should be used cautiously at eGFR 30–45. Glipizide causes hypoglycemia and has
no CV/renal benefit. Pioglitazone causes fluid retention, worsening heart failure risk. Sitagliptin
has neutral CV effects and no significant renal benefit."
question:6. "A 32-year-old man presents with acute monoarthritis of the right first
metatarsophalangeal joint. The joint is erythematous, warm, swollen, and exquisitely tender. He
reports drinking beer at a party last night. Serum uric acid is 9.2 mg/dL. Joint aspira tion reveals
negatively birefringent, needle-shaped crystals under polarized light microscopy. What is the
most appropriate treatment?",
"A. Allopurinol",
"B. Indomethacin",
"C. Colchicine at urate-lowering doses",
"D. Febuxostat",
