護理師照護一名剛進行全髖關節置換術的病人。為了預防假體脫位，護理師應維持何種擺位？
A nurse is caring for a client who has just undergone a total hip arthroplasty. Which position should the nurse maintain to prevent dislocation of the prosthesis?
- AFlexion of the hip greater than 90 degrees髖關節屈曲超過90度
- BAdduction using a pillow between knees使用膝間枕頭進行內收
- CAbduction using an abduction pillow✓ 正解使用外展枕進行外展
- DInternal rotation of the affected leg患肢內旋
全髖關節置換術（Total Hip Arthroplasty）術後，關節囊尚未癒合，極易發生假體脫位（Dislocation）。護理師必須嚴格教導與協助病人維持「預防脫位姿勢」。核心原則是避免患側髖關節過度屈曲（>90度）、內收（Adduction）及內旋（Internal rotation）。使用外展枕（Abduction pillow）將雙腿分開，能有效維持外展姿勢，確保假體穩定在關節窩內。
After total hip arthroplasty, the joint capsule has not yet healed and is highly prone to prosthesis dislocation. The nurse must rigorously teach and assist the client in maintaining a 'dislocation-prevention position.' The core principles are to avoid excessive hip flexion (>90 degrees), adduction, and internal rotation on the affected side. Using an abduction pillow to separate the legs effectively maintains abduction and keeps the prosthesis stable within the acetabulum.
