Pediatric rheumatoid arthritis is a form of arthritis that affects approximately 1 in 1,000 children each year. It involves inflammation of one or more joints and can cause pain, swelling, and stiffness. The most common types are juvenile rheumatoid arthritis and arthritis following a viral or bacterial infection. Treatment focuses on controlling inflammation through medications like DMARDs and biologics to prevent joint damage and disability. Nurses monitor for signs of arthritis, ensure proper treatment, educate patients and families, and help patients manage pain and maintain function.
