सही: ० / ०
-
A short PR interval with a slurred upstroke of the QRS complex (delta wave) is characteristic of:
सही उत्तर: घ) Wolff-Parkinson-White syndrome
In WPW syndrome an accessory pathway pre-excites the ventricles, producing a short PR interval and a delta wave.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Alternate strong and weak pulse beats with a regular rhythm (pulsus alternans) indicate:
सही उत्तर: घ) Severe left ventricular failure
Pulsus alternans is a sign of severe left ventricular systolic dysfunction.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The murmur of hypertrophic obstructive cardiomyopathy characteristically becomes louder with:
सही उत्तर: ग) The Valsalva manoeuvre
Valsalva reduces venous return and left ventricular size, which increases the outflow obstruction and the murmur in HOCM.

-
The first-line drug for symptomatic sinus bradycardia with hypotension is intravenous:
सही उत्तर: ख) Atropine
Atropine blocks vagal tone on the SA and AV nodes and is the initial drug for symptomatic bradycardia.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Widespread concave (saddle-shaped) ST elevation with PR-segment depression on the ECG suggests:
सही उत्तर: घ) Acute pericarditis
Acute pericarditis causes diffuse concave ST elevation not confined to one arterial territory, often with PR depression.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
A paradoxical rise of the jugular venous pressure on inspiration (Kussmaul's sign) is characteristic of:
सही उत्तर: घ) Constrictive pericarditis
In constrictive pericarditis the rigid pericardium prevents the right heart from accepting the extra inspiratory venous return, so the JVP rises.

-
Glucagon is especially useful as an antidote in overdose of which drug group?
सही उत्तर: क) Beta-blockers
Glucagon raises intracellular cAMP independently of beta-receptors, improving heart rate and contractility in beta-blocker poisoning.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The specific antidote for life-threatening digoxin toxicity is:
सही उत्तर: क) Digoxin-specific antibody (Fab) fragments
Digoxin-specific Fab fragments bind free digoxin and rapidly reverse life-threatening toxicity such as dangerous arrhythmias or severe hyperkalaemia.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
In adult cardiopulmonary resuscitation, chest compressions should be delivered at a rate of:
सही उत्तर: घ) 100–120 per minute
Current resuscitation guidelines recommend compressions at 100–120 per minute with a depth of 5–6 cm in adults.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Which cardiac arrest rhythms are 'shockable', i.e. treated with defibrillation?
सही उत्तर: ग) Ventricular fibrillation and pulseless ventricular tachycardia
Only VF and pulseless VT respond to defibrillation; asystole and PEA are non-shockable and managed with CPR and adrenaline.
