護理師照顧一位全髖關節置換術後的病患。哪些措施適合預防併發症？（選所有適合的）
A nurse is caring for a client who is post-operative following a total hip arthroplasty. Which interventions are appropriate to prevent complications? (Select all that apply.)
- AUse an abduction pillow between the legs✓ 正解在雙腿之間使用外展枕
- BAvoid bending the hip beyond 90 degrees✓ 正解避免髖關節彎曲超過 90 度
- CEncourage the client to cross their legs when sitting鼓勵病人在坐著時交叉雙腿
- DApply sequential compression devices (SCDs) as ordered✓ 正解依醫囑使用順序加壓裝置（SCDs）
- EInstruct the client to avoid internal rotation of the affected hip✓ 正解指示病人避免患側髖關節內旋
全髖關節置換術（Total Hip Arthroplasty）術後照護的核心在於預防「假體脫位（Dislocation）」與「深部靜脈栓塞（DVT）」。脫位通常發生在髖關節過度彎曲、內收或內旋時。護理措施必須嚴格指導病人避免超過 90 度的屈曲，並使用輔助設備（如外展枕）來固定關節位置。此外，術後活動能力下降使得 DVT 風險大增，使用機械式預防措施如 SCD 是臨床標準流程。
Care after total hip arthroplasty centers on preventing prosthetic dislocation and deep vein thrombosis (DVT). Dislocation typically occurs with excessive hip flexion, adduction, or internal rotation. Nursing measures must strictly instruct the client to avoid flexion beyond 90 degrees and use assistive devices (such as an abduction pillow) to maintain joint position. In addition, reduced postoperative mobility greatly increases DVT risk, and mechanical prophylaxis such as sequential compression devices is a standard clinical practice.
