Which pattern of laboratory findings is typical of disseminated intravascular coagulation?
सही उत्तर: ग) Low platelets, low fibrinogen, raised D-dimer
DIC consumes platelets and clotting factors while fibrinolysis raises D-dimer; PT and aPTT are prolonged. Isolated thrombocytopenia with normal coagulation suggests ITP.

A boy with haemarthrosis has a prolonged aPTT, normal PT and normal platelet count. The most likely deficiency is:
सही उत्तर: ख) Factor VIII

Which iron study pattern is typical of iron deficiency anaemia?

-
An elderly patient with new temporal headache, jaw claudication and raised ESR should be treated immediately with:
सही उत्तर: ग) High-dose corticosteroids
Giant cell arteritis threatens irreversible blindness, so steroids are started at once without waiting for temporal artery biopsy. NSAIDs and triptans do not prevent ischaemic complications.

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

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.
