一位接受全髖關節置換術的術後病人，護理師應優先採取哪項措施以預防併發症？
A nurse is caring for a client who is post-operative following a total hip arthroplasty. Which intervention is the priority to prevent complications?
- AChange the surgical dressing every 4 hours每 4 小時更換手術敷料
- BMaintain the client in high-Fowler's position維持病人於高福勒氏體位（High-Fowler's position）
- CKeep the hip in a position of adduction保持髖關節處於內收位置
- DEncourage early ambulation and use of SCDs✓ 正解鼓勵早期下床活動並使用漸進式加壓裝置（SCDs）
全髖關節置換術（THA）後，病人因手術創傷、血管內皮受損及術後活動受限，處於深部靜脈栓塞（DVT）的高風險狀態。為了降低血栓風險，護理師應優先促進下肢血液循環，以預防靜脈血栓栓塞症（VTE）。早期活動（Early ambulation）是臨床上最有效且低成本的預防措施，配合間歇性充氣加壓器（SCDs）能進一步減少血液鬱積。
After total hip arthroplasty (THA), patients are at high risk for deep vein thrombosis (DVT) because of surgical trauma, damage to the vascular endothelium, and postoperative immobility. To reduce the risk of thrombosis, the nurse should prioritize promoting lower extremity blood circulation to prevent venous thromboembolism (VTE). Early ambulation is the most effective and low-cost preventive measure in clinical practice, and combining it with sequential compression devices (SCDs) can further reduce venous stasis.
