護理師照護一位髖關節置換術後病人，下列哪項介入措施對於降低深部靜脈栓塞（DVT）風險至關重要？
A nurse is caring for a client who is post-operative following a total hip arthroplasty. Which intervention is essential to reduce the risk of deep vein thrombosis (DVT)?
- AKeep the knees flexed at a 90-degree angle保持膝蓋屈曲呈九十度角
- BMassage the lower extremities twice daily每天兩次按摩下肢
- CApply sequential compression devices✓ 正解應用序貫加壓裝置
- DMaintain bed rest for 48 hours維持卧床休息四十八小時
髖關節置換術後病人因長期臥床、手術部位組織損傷及血管受壓，極易發生深部靜脈栓塞（DVT）。預防 DVT 的核心機轉在於「促進靜脈回流」與「預防血液淤滯」。連續性加壓裝置（SCD）透過規律的充氣與洩氣，模擬肌肉幫浦功能，顯著降低血栓形成風險。臨床護理應採取主動介入措施，包括鼓勵儘早活動、水分補充及使用抗凝血藥物，而非單純依賴臥床。
Clients after total hip arthroplasty are highly susceptible to deep vein thrombosis (DVT) because of prolonged bed rest, surgical tissue injury, and vascular compression. The core mechanism for preventing DVT is to promote venous return and prevent venous stasis. Sequential compression devices (SCDs) mimic the muscle pump function through rhythmic inflation and deflation, significantly reducing the risk of clot formation. Clinical nursing should adopt active interventions including early ambulation, hydration, and use of anticoagulants, rather than relying solely on bed rest.
在美國臨床實務中，SCD 的使用頻率極高且有嚴格的護理紀錄要求。台灣臨床中較常見鼓勵病人穿著彈性襪（TED stockings）搭配 SCD，美國則更強調在病人清醒且未下床時須持續配戴 SCD。
