1. A 67-year-old man presents to the emergency department with
crushing substernal chest pain radiating to his jaw for 45 minutes.
He has diabetes, hypertension, and chronic kidney disease. ECG
reveals ST-segment elevation in leads II, III, and aVF. Blood
pressure is 88/54 mmHg and lungs are clear.
What is the most appropriate next step?
A. IV nitroglycerin infusion
B. Immediate PCI with aspirin and heparin
C. Metoprolol IV bolus
D. Furosemide IV
E. Stress echocardiography
Answer: B. Immediate PCI with aspirin and heparin
Rationale: Inferior STEMI with hypotension suggests possible right
ventricular involvement. Immediate reperfusion with PCI is lifesaving.
Nitroglycerin may worsen hypotension by reducing preload. Stress
testing is contraindicated during acute MI.
2. A 54-year-old woman complains of fatigue, weight gain,
constipation, and cold intolerance. Examination reveals delayed
relaxation of deep tendon reflexes. TSH is elevated and free T4 is
decreased.
,Which is the most likely diagnosis?
A. Graves disease
B. Secondary hypothyroidism
C. Hashimoto thyroiditis
D. Thyroid storm
E. Subacute thyroiditis
Answer: C. Hashimoto thyroiditis
Rationale: Primary hypothyroidism with elevated TSH and low free T4 is
most commonly caused by autoimmune destruction of the thyroid
gland. Delayed DTR relaxation is a classic finding.
3. A 72-year-old man develops fever, productive cough, confusion,
and hypotension. Chest x-ray shows right lower lobe
consolidation.
What is the first priority?
A. Oral azithromycin
B. IV fluids and broad-spectrum antibiotics
C. Bronchoscopy
D. Chest physiotherapy
E. Prednisone
Answer: B. IV fluids and broad-spectrum antibiotics
Rationale: Septic shock secondary to pneumonia requires rapid fluid
resuscitation and antibiotics within the first hour. Delays significantly
increase mortality.
4. A patient with atrial fibrillation suddenly develops right-sided
weakness and aphasia.
Which cerebral artery is most likely occluded?
,A. Anterior cerebral artery
B. Posterior cerebral artery
C. Middle cerebral artery
D. Basilar artery
E. Vertebral artery
Answer: C. Middle cerebral artery
Rationale: Contralateral hemiparesis with aphasia localizes to the
dominant MCA territory, commonly affected by cardioembolic strokes
from atrial fibrillation.
5. A 30-year-old woman presents with tremor, anxiety, palpitations,
and weight loss. TSH is suppressed and free T4 elevated.
The most likely diagnosis is:
A. Hashimoto thyroiditis
B. Graves disease
C. Toxic adenoma
D. Pituitary adenoma
E. De Quervain thyroiditis
Answer: B. Graves disease
Rationale: Diffuse hyperthyroidism with ophthalmopathy and
suppressed TSH is characteristic of Graves disease due to thyroid-
stimulating immunoglobulins.
6. A diabetic patient presents with polyuria, abdominal pain, and
Kussmaul respirations. Glucose is 540 mg/dL and serum
bicarbonate is 10 mEq/L.
Initial therapy includes:
A. Sodium bicarbonate only
B. Regular insulin infusion and IV fluids
, C. Metformin
D. Furosemide
E. Oral potassium
Answer: B. Regular insulin infusion and IV fluids
Rationale: DKA treatment begins with isotonic saline followed by insulin
infusion while closely monitoring potassium.
7. A 65-year-old smoker develops hematuria without pain.
The most concerning diagnosis is:
A. Nephrolithiasis
B. Cystitis
C. Renal infarction
D. Bladder carcinoma
E. Glomerulonephritis
Answer: D. Bladder carcinoma
Rationale: Painless gross hematuria in an older smoker is bladder
cancer until proven otherwise.
8. A patient develops sudden tearing chest pain radiating to the back
with unequal arm blood pressures.
Diagnosis?
A. Pericarditis
B. Pulmonary embolism
C. Aortic dissection
D. GERD
E. Myocarditis
Answer: C. Aortic dissection
