सही: ० / ०
-
Type 2 (hypercapnic) respiratory failure is defined by hypoxaemia together with:
सही उत्तर: ग) Raised PaCO₂ (above about 50 mmHg)
Type 1 failure is hypoxaemia with normal or low PaCO₂; type 2 adds hypercapnia, reflecting alveolar hypoventilation.

-
The diffusing capacity for carbon monoxide (DLCO) is characteristically INCREASED in:
सही उत्तर: घ) Diffuse alveolar haemorrhage
Blood in the alveoli binds CO, raising DLCO; it also rises in polycythaemia and asthma, whereas emphysema, fibrosis and pulmonary vascular disease reduce it.

-
In restrictive lung disease such as pulmonary fibrosis, spirometry typically shows:
सही उत्तर: ख) Reduced FVC with normal or raised FEV1/FVC ratio
Restriction reduces lung volumes proportionately (FEV1 and FVC both fall), so the ratio is preserved or high; obstruction lowers the ratio.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Digital clubbing is NOT a typical feature of:
सही उत्तर: ग) Uncomplicated chronic obstructive pulmonary disease
Clubbing occurs in suppurative lung disease, fibrosis and lung cancer; its presence in COPD should prompt a search for another cause such as malignancy.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The hallmark of hypertrophic cardiomyopathy on echocardiography is:
सही उत्तर: क) Asymmetric septal hypertrophy
HCM typically shows asymmetric hypertrophy of the interventricular septum, often with systolic anterior motion of the mitral valve.

-
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.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
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.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
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.
