護理師照護一位接受全髖關節置換術的術後病人。為預防髖關節脫位，護理師應執行哪項措施？
A nurse is caring for a postoperative client who had a total hip arthroplasty. To prevent hip dislocation, which action should the nurse implement?
- AEncourage the client to cross their legs while sitting鼓勵病人在坐著時交叉雙腿
- BKeep the operative hip in adduction at all times使手術側髖關節始終保持內收
- CPlace an abduction pillow between the client's legs✓ 正解在病人雙腿之間放置外展枕
- DEnsure the hip is flexed beyond 90 degrees when seated確保病人坐著時髖關節屈曲超過90度
全髖關節置換術後，預防脫位的關鍵是避免髖關節過度屈曲（>90度）、內收及內旋。使用外展枕頭能維持髖關節在正確的對位。過度屈曲、交叉腿或內收動作均會導致股骨頭從關節窩滑脫，增加脫位風險，術後早期需嚴格限制這類活動以利組織癒合。
After total hip arthroplasty, the key to preventing dislocation is to avoid excessive flexion (>90 degrees), adduction, and internal rotation of the hip. Using an abduction pillow maintains proper alignment of the hip. Excessive flexion, leg crossing, or adduction can all cause the femoral head to slip out of the acetabulum, increasing dislocation risk. These activities must be strictly limited in the early postoperative period to allow tissue healing.
美國醫院常見術後使用專用外展枕；台灣則多使用捲起的棉被或一般枕頭替代。
