উত্তর
সঠিক উত্তর: ক
Initiate disease-modifying anti-rheumatic drugs (DMARDs) as early as possible.
ক
ব্যাখ্যা
Current guidelines for RA emphasize early and aggressive treatment with disease-modifying anti-rheumatic drugs (DMARDs), typically methotrexate, within 3 months of diagnosis. This "treat-to-target" strategy aims to achieve remission or low disease activity to prevent irreversible joint damage and improve long-term outcomes. Delaying DMARDs allows progression of structural damage.
