Antibodies most specific for systemic lupus erythematosus are:
सही उत्तर: क) Anti-Smith and anti-dsDNA
Anti-dsDNA and anti-Sm are highly specific for SLE, and anti-dsDNA tracks disease activity and nephritis. Anti-histone antibodies are typical of drug-induced lupus.

The autoantibody with the highest specificity for rheumatoid arthritis is:
सही उत्तर: घ) Anti-cyclic citrullinated peptide (anti-CCP)
Anti-CCP antibodies are highly specific for RA and predict erosive disease. Rheumatoid factor is sensitive but also positive in many other conditions and in healthy elderly people.

Yellow-green visual disturbance (xanthopsia) is a classic feature of toxicity of:
सही उत्तर: ग) Digoxin
Digoxin toxicity causes visual changes, nausea and arrhythmias, and is worsened by hypokalaemia. Ethambutol causes optic neuritis with red-green colour blindness.

The CHA₂DS₂-VASc score is used in atrial fibrillation to estimate:
सही उत्तर: ख) Risk of stroke
CHA₂DS₂-VASc estimates stroke risk and guides anticoagulation in non-valvular AF. Bleeding risk is assessed with scores such as HAS-BLED.

For primary prophylaxis of variceal bleeding in cirrhosis with large varices, the commonly used drug is:
सही उत्तर: क) Propranolol
Non-selective beta-blockers such as propranolol or carvedilol reduce portal pressure and prevent first bleeding. Octreotide and terlipressin are used in acute variceal bleeding, not long-term prophylaxis.

Hypercalcaemia due to PTH-related peptide is most typically associated with which lung cancer?
सही उत्तर: घ) Squamous cell carcinoma
Squamous cell carcinoma of the lung commonly secretes PTHrP, causing humoral hypercalcaemia of malignancy. Small cell carcinoma is associated with SIADH and ectopic ACTH.

Bence Jones proteinuria, punched-out lytic skull lesions and rouleaux formation suggest:
सही उत्तर: ग) Multiple myeloma
Multiple myeloma is a plasma cell malignancy producing monoclonal light chains (Bence Jones proteins) and osteolytic lesions. Prostate cancer metastases are typically osteoblastic (sclerotic).

-
Hypoglycaemia with a high serum insulin but low C-peptide level suggests:
सही उत्तर: ख) Exogenous insulin administration
Commercial insulin lacks C-peptide, so exogenous insulin raises insulin but suppresses endogenous C-peptide. Insulinoma and sulfonylureas raise both insulin and C-peptide.

-
The main specific antidote used in organophosphate poisoning to reverse muscarinic effects is:
सही उत्तर: क) Atropine
Organophosphates inhibit acetylcholinesterase; atropine blocks the resulting muscarinic overactivity and is titrated to dry chest secretions. Physostigmine is itself a cholinesterase inhibitor and would worsen toxicity.

In people living with HIV, cotrimoxazole prophylaxis against Pneumocystis pneumonia is indicated when the CD4 count falls below:
सही उत्तर: घ) 200 cells/µL
A CD4 count below 200 cells/µL markedly increases the risk of Pneumocystis jirovecii pneumonia. A CD4 below 50 is the threshold for Mycobacterium avium complex risk.
