Q. Biconvex intracranial hemorrhage indicates?
A. Epidural hematoma
Footnote
- Middle meningeal artery tear → epidural hematoma.
- Does not cross sutures (contrast: subdural hematoma is crescent‑shaped and can cross sutures but not midline falx).
Epidural hematoma = biconvex, arterial bleed, lucid interval.
Subdural hematoma = crescent shaped, venous bleed (bridging veins).
Q. Blue sclera with recurrent fractures indicates defect in which collagen?
A. Type I collagen
Footnote: Osteogenesis imperfecta.
Asthmatic with cirrhosis on propranolol—best alternative?
A. Metoprolol
Footnote: β1-selective and safer in liver disease.
Q. Preferred thrombolytic in STEMI?
A. Tenecteplase
Footnote: Fibrin-specific, single bolus, less antigenic than streptokinase.
Q. Cause of metabolic acidosis in burns?
A. Lactic acidosis
Footnote: Tissue hypoxia → high anion gap metabolic acidosis.
High AG → think of extra acids (lactate, ketones, toxins).
Normal AG → think of bicarbonate loss with chloride retention.
Q. Acute control of thyrotoxicosis with tachycardia?
A. Propranolol
Footnote: Also inhibits peripheral T4→T3 conversion.
