護理師照護一名全髖關節置換術後的病人，下列哪項措施能有效預防髖關節脫位？
A nurse is caring for a client who is post-operative following a total hip arthroplasty. Which action by the nurse helps prevent hip dislocation?
- AAssisting the client to bend the hip more than 90 degrees協助病人使髖關節彎曲超過90度
- BEncouraging the client to sit in a low-seated chair鼓勵病人坐在低矮的椅子上
- CTurning the client toward the operative side將病人轉向手術側
- DPlacing an abduction pillow between the legs✓ 正解在雙腿之間放置外展枕
全髖關節置換術（Total Hip Arthroplasty, THA）後的病人，最常見的術後併發症是假體脫位（Dislocation）。術後護理的核心原則是「髖關節保護（Hip Precautions）」，包括避免患肢過度內收（Adduction）、過度屈曲（>90度）及內旋。使用外展枕頭（Abduction pillow）能確保患肢維持外展姿勢，防止雙腿交叉導致假體脫出。
Placing an abduction pillow between the legs helps maintain hip alignment and prevents adduction, which is a primary cause of dislocation after total hip arthroplasty. Nurses must avoid hip flexion greater than 90 degrees, crossing the legs, or turning the client toward the operative side, as these actions increase the risk of prosthetic displacement.
美國醫院臨床中，術後使用外展枕頭（Abduction Pillow）或專用護具非常普遍，並會嚴格要求病人使用輔助工具如加高馬桶座（Raised toilet seat）來避免屈曲超過 90 度。
