護理師照顧全髖關節置換術後病人，採取何項行動可預防假體脫位？
A nurse is caring for a client who had a total hip arthroplasty. Which action is appropriate to prevent dislocation of the prosthesis?
- ACross the legs while in bed卧床時交叉雙腿
- BKeep the operated leg in adduction保持手術側腿部內收
- CFlex the hip to 110 degrees when sitting坐著時將髖關節彎曲至 110 度
- DPlace an abduction pillow between the legs✓ 正解雙腿之間放置外展枕
— Explanation · 中文詳解 —
全髖關節置換後需避免過度彎曲（>90度）、內收（Adduction）與內旋（Internal rotation）。使用外展枕（Abduction pillow）可維持兩腿分開，防止內收，進而降低假體脫位風險。
Placing an abduction pillow between the legs is appropriate to maintain proper hip alignment and prevent adduction, which is a primary cause of prosthetic dislocation. After total hip arthroplasty, clients must avoid flexing the hip beyond 90 degrees, crossing the legs, or internally rotating the operative limb. The abduction pillow ensures the legs remain separated, thereby protecting the new joint from dislocation during rest and movement.
✦ 台美臨床差異
兩地手術後護理常規相似，但在美國使用外展枕較普遍，台灣則常強調病人的居家輔具適應。
