-
Which class of antihypertensive drugs commonly causes ankle oedema?
सही उत्तर: क) Dihydropyridine calcium channel blockers (e.g. amlodipine)
Amlodipine dilates precapillary arterioles more than venules, raising capillary pressure and causing dependent oedema that does not respond well to diuretics.

A young man with a family history of sudden death has an ECG showing a right bundle branch block pattern with coved ST elevation in V1–V3. The likely diagnosis is:
सही उत्तर: ख) Brugada syndrome
Brugada syndrome is a sodium channelopathy (often SCN5A) with coved ST elevation in right precordial leads and a risk of ventricular fibrillation.

Osborn (J) waves at the junction of the QRS and ST segment are characteristic of:
सही उत्तर: घ) Hypothermia
J (Osborn) waves are positive deflections at the J point that become more prominent as core temperature falls.

-
Sagging ('reverse tick') ST-segment depression on the ECG in a patient on long-term treatment is a sign of:
सही उत्तर: ग) Digoxin effect
Digoxin produces scooped ST depression, T-wave flattening and a short QT at therapeutic levels; this 'digoxin effect' does not by itself mean toxicity.

-
A third heart sound (S3) in an adult over 40 years most often indicates:
सही उत्तर: घ) Ventricular volume overload or systolic failure
S3 is produced by rapid early diastolic filling into a dilated or failing ventricle; S4 reflects atrial contraction into a stiff ventricle.

-
A bisferiens pulse (two systolic peaks) is classically felt in:
सही उत्तर: क) Combined aortic stenosis and aortic regurgitation with dominant regurgitation
Pulsus bisferiens occurs in mixed aortic valve disease with predominant regurgitation and in hypertrophic obstructive cardiomyopathy.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
A slow-rising, low-volume pulse (pulsus parvus et tardus) is characteristic of:
सही उत्तर: ख) Aortic stenosis
Fixed obstruction to left ventricular outflow in aortic stenosis produces a small, slowly rising arterial pulse.

-
Intermittent 'cannon' a waves in the jugular venous pulse are characteristic of:
सही उत्तर: ग) Complete (third-degree) heart block
Cannon a waves occur when the right atrium contracts against a closed tricuspid valve; irregular cannon waves indicate atrioventricular dissociation, as in complete heart block.

-
SIADH is characterised by:
सही उत्तर: क) Euvolaemic hyponatraemia with inappropriately concentrated urine
In SIADH, excess ADH causes water retention with hyponatraemia, low serum osmolality and urine that is inappropriately concentrated, with normal volume status. Fluid restriction is the first-line treatment.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Diabetic ketoacidosis: the first priority in management is:
सही उत्तर: घ) Intravenous isotonic saline
Patients with DKA are severely dehydrated, so IV 0.9% saline is started first, followed by a fixed-rate IV insulin infusion with potassium monitoring. Bicarbonate is reserved for very severe acidosis.
