護理師照護一位剛完成全髖關節置換術的病人，為預防脫位，應採取哪種姿勢？
A nurse is caring for a client who has just undergone a total hip arthroplasty. Which position should the nurse maintain to prevent dislocation?
- AAbduction of the affected leg✓ 正解患肢外展
- BAdduction of the affected leg患肢內收
- CInternal rotation of the affected leg患肢內旋
- DFlexion of the hip past 90 degrees髖關節屈曲超過90度
— Explanation · 中文詳解 —
全髖關節置換術後，預防脫位的關鍵在於避免患肢過度內收（Adduction）、內轉（Internal rotation）及過度屈曲（>90度）。採取外展姿勢（Abduction）能將股骨頭固定在髖臼內，維持關節穩定性，是術後初期最重要的擺位原則。
After total hip arthroplasty, the key to preventing dislocation is to avoid excessive adduction, internal rotation, and excessive flexion (>90 degrees) of the affected limb. The abduction position holds the femoral head within the acetabulum and maintains joint stability; it is the most important positioning principle in the early postoperative period.
✦ 台美臨床差異
美台皆強調術後輔具（如外展枕）的使用，但台灣對於術後早期下床活動的介入標準較為嚴謹。
