This document provides an overview of rheumatoid arthritis, including its definition, signs and symptoms, causes, risk factors, complications, diagnosis, treatment, and nursing care. Rheumatoid arthritis is an autoimmune disorder where the immune system attacks joints, causing painful swelling. It most commonly affects adults over 50 and women. Smoking and excess weight can increase risk. Treatment focuses on reducing inflammation and symptoms through medications like NSAIDs, steroids, and disease-modifying drugs. Nurses assess patients, provide comfort measures, educate on disease management, and ensure patients can care for themselves.
