一位接受髖關節置換術後的病人，下列哪項措施對於預防術後靜脈血栓栓塞最有效？
A nurse is caring for a client who is post-operative following a hip arthroplasty. Which intervention is most effective in preventing postoperative venous thromboembolism?
- AApply sequential compression devices✓ 正解使用間歇性氣壓加壓裝置
- BElevate the lower extremities above heart level將下肢抬高過心臟水平
- CMaintain strict bed rest for 48 hours嚴格臥床休息48小時
- DEncourage frequent deep breathing exercises鼓勵頻繁進行深呼吸練習
髖關節手術後血液滯留風險高，使用間歇性氣壓式腿部加壓器（SCD）能促進下肢靜脈回流，降低深部靜脈栓塞發生率。深呼吸雖能預防肺部併發症，但與預防血栓無直接關聯。術後應儘早活動而非臥床，抬高患肢雖然可行但並非預防血栓的首選物理輔助工具。
After hip surgery, the risk of venous stasis is high, and sequential compression devices (SCDs) promote venous return from the lower extremities, reducing the incidence of deep vein thrombosis. Deep breathing helps prevent pulmonary complications but has no direct effect on thrombosis prevention. Early postoperative ambulation should be encouraged rather than bed rest; while elevating the affected limb is acceptable, it is not the primary physical adjunct for thrombosis prevention.
美台臨床皆重視機械性預防，但美國護理師常需更主動依據風險評估開啟 SCD 使用時間。
