護理師照護一位剛接受全髖關節置換術的病人，為預防脫位，下列何種姿勢最為優先維持？
A nurse is caring for a client who has just undergone a total hip arthroplasty. Which position is the highest priority to maintain to prevent dislocation?
- AInternal rotation of the affected extremity患肢內旋
- BFlexion of the hip joint beyond 90 degrees髖關節屈曲超過90度
- CAbduction of the affected leg using an abduction pillow✓ 正解使用外展枕使患肢外展
- DAdduction of the operated leg across the midline患肢內收跨過身體中線
全髖關節置換術（Total hip arthroplasty）後，術後照護的優先目標是預防人工關節脫位（Dislocation）。術後初期關節周圍組織尚未癒合，必須嚴格維持正確的姿勢，避免過度彎曲、內收或內旋。使用外展枕（Abduction pillow）將雙腿分開，能有效將股骨頭固定在髖臼內，是預防脫位最直接且關鍵的護理措施。
After total hip arthroplasty, the priority goal of postoperative care is to prevent dislocation of the prosthetic joint. In the early postoperative period, tissues around the joint have not yet healed, so correct positioning must be strictly maintained to avoid excessive flexion, adduction, or internal rotation. Using an abduction pillow to keep the legs apart effectively keeps the femoral head within the acetabulum, making it the most direct and critical nursing intervention to prevent dislocation.
