護理師指導類風濕性關節炎病人關於關節保護的原則，下列何者正確？
A nurse is teaching a client with rheumatoid arthritis about joint protection. Which instruction is accurate?
- AMaintain joints in a flexed position to minimize strain保持關節處於屈曲姿勢以減輕負擔
- BUse the strongest joints for tasks to distribute weight✓ 正解使用最強壯的關節進行工作以分散重量
- CApply heat for acute inflammatory flare-ups在急性發炎發作時應用熱敷
- DIncrease activity regardless of pain level無論疼痛程度如何，均增加活動量
類風濕性關節炎（RA）是一種慢性自體免疫疾病，會導致關節變形與功能喪失。關節保護原則（Joint protection principles）的核心在於將壓力分散至較大的關節，減少小關節（如手指）的負擔。活動時應考量疼痛程度，適度運動有助於維持活動度，但急性發炎期應以休息與物理治療為主。正確的姿勢與用力方式能有效減緩關節損傷的進程。
Rheumatoid arthritis (RA) is a chronic autoimmune disease that leads to joint deformity and loss of function. The principle of joint protection is to distribute force across larger joints and reduce the load on smaller joints (such as the fingers). Activity should consider the level of pain; moderate exercise helps maintain range of motion, but acute flares should be managed mainly with rest and physical therapy. Proper posture and force application effectively slow the progression of joint damage.
