The murmur of aortic stenosis is typically:
सही उत्तर: ग) Ejection systolic, radiating to the carotids
Aortic stenosis gives a crescendo-decrescendo ejection systolic murmur in the aortic area radiating to the neck. A pansystolic murmur radiating to the axilla is mitral regurgitation.

Hypotension, raised jugular venous pressure and muffled heart sounds (Beck's triad) suggest:
सही उत्तर: ख) Cardiac tamponade
Beck's triad is the classic sign of cardiac tamponade, often with pulsus paradoxus. Tension pneumothorax also causes hypotension and raised JVP but has absent breath sounds and tracheal deviation, not muffled heart sounds.

Which of the following is a MAJOR criterion in the revised Jones criteria for acute rheumatic fever?
सही उत्तर: क) Sydenham chorea
Major criteria include carditis, arthritis, chorea, erythema marginatum and subcutaneous nodules. Fever, raised ESR/CRP and prolonged PR interval are minor criteria.

In infective endocarditis among intravenous drug users, the most commonly affected valve is:
सही उत्तर: घ) Tricuspid valve
Injected bacteria (commonly Staphylococcus aureus) first meet the right-sided valves, so the tricuspid valve is most often involved. Septic pulmonary emboli are a common complication.

The first-line treatment of torsades de pointes is:
सही उत्तर: ग) Intravenous magnesium sulfate
Magnesium sulfate is first-line for torsades even when serum magnesium is normal. Amiodarone, sotalol and procainamide prolong the QT interval and can worsen it.

A haemodynamically stable patient has regular narrow-complex SVT that persists after vagal manoeuvres. The drug of choice is:
सही उत्तर: ख) Intravenous adenosine
Adenosine transiently blocks AV nodal conduction and terminates most re-entrant SVTs. Lidocaine is a ventricular antiarrhythmic and has no role in SVT.

A short PR interval with a slurred upstroke of the QRS (delta wave) is seen in:
सही उत्तर: क) Wolff–Parkinson–White syndrome
In WPW an accessory pathway (bundle of Kent) pre-excites the ventricle, producing a short PR and delta wave. First-degree block has a prolonged PR.

ST elevation in leads II, III and aVF indicates infarction of which wall, usually supplied by which artery?
सही उत्तर: घ) Inferior wall – right coronary artery
Leads II, III and aVF face the inferior wall, which is usually supplied by the right coronary artery. Anterior MI shows changes in V1–V4 (LAD territory).

Serum calcium is 7.6 mg/dL and albumin is 2.0 g/dL. The albumin-corrected calcium is:
सही उत्तर: ग) 9.2 mg/dL
Corrected Ca = measured Ca + 0.8 × (4.0 − albumin) = 7.6 + 0.8 × 2 = 9.2 mg/dL, which is normal. Low albumin lowers total but not ionised calcium.

In metabolic acidosis with HCO₃⁻ of 12 mmol/L, Winter's formula predicts an expected PaCO₂ of about:
सही उत्तर: ख) 26 ± 2 mmHg
Winter's formula: expected PaCO₂ = 1.5 × HCO₃⁻ + 8 ± 2 = 1.5 × 12 + 8 = 26 ± 2 mmHg. A higher measured PaCO₂ indicates a coexisting respiratory acidosis.
