Raised CSF protein with a normal CSF cell count (albuminocytological dissociation) is typical of:
सही उत्तर: क) Guillain–Barré syndrome
GBS is an acute immune-mediated demyelinating polyneuropathy with ascending weakness and areflexia. Bacterial and tuberculous meningitis show raised cell counts.

Myasthenia gravis is most commonly caused by antibodies against:
सही उत्तर: घ) Postsynaptic acetylcholine receptors
Antibodies against nicotinic acetylcholine receptors cause fatigable weakness in myasthenia gravis. Antibodies to presynaptic calcium channels cause Lambert–Eaton syndrome.

-
Bilateral hilar lymphadenopathy with non-caseating granulomas and raised serum ACE suggests:
सही उत्तर: ग) Sarcoidosis
Sarcoidosis is a multisystem granulomatous disease with typical non-caseating granulomas and bilateral hilar lymphadenopathy. Tuberculosis produces caseating granulomas.

-
Airflow obstruction on spirometry is confirmed by a post-bronchodilator FEV1/FVC ratio of less than:
सही उत्तर: ख) 0.70
GOLD defines persistent airflow limitation as post-bronchodilator FEV1/FVC

Apart from smoking cessation, which intervention improves survival in COPD with chronic hypoxaemia?
सही उत्तर: क) Long-term oxygen therapy
Long-term oxygen therapy (at least 15 hours/day) improves survival in COPD with chronic hypoxaemia. Bronchodilators improve symptoms but have not been shown to prolong life.

The imaging investigation of choice for suspected pulmonary embolism in a stable patient with normal renal function is:
सही उत्तर: घ) CT pulmonary angiography
CT pulmonary angiography directly shows filling defects in pulmonary arteries. A V/Q scan is an alternative when contrast is contraindicated.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The most common ECG finding in acute pulmonary embolism is:

-
Which drug has been shown to reduce mortality in heart failure with reduced ejection fraction?
सही उत्तर: ख) Spironolactone
Mineralocorticoid receptor antagonists such as spironolactone reduce mortality in HFrEF (RALES trial). Furosemide and digoxin improve symptoms and hospitalisation but not survival.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Dry cough caused by ACE inhibitors is due to accumulation of:
सही उत्तर: क) Bradykinin
ACE also breaks down bradykinin, so ACE inhibitors raise bradykinin levels and cause cough and angioedema. Angiotensin receptor blockers do not affect bradykinin and are the usual substitute.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The murmur of hypertrophic obstructive cardiomyopathy becomes louder with:
सही उत्तर: घ) Valsalva manoeuvre
Valsalva reduces venous return and left ventricular size, increasing outflow obstruction. Squatting and handgrip increase LV volume/afterload and soften the murmur.
