護理師照護一名全髖關節置換術後病人，哪項介入措施對於降低肺栓塞風險最重要？
A nurse is caring for a client who is post-operative following a total hip arthroplasty. Which intervention is the highest priority to reduce the risk of a pulmonary embolism?
- AApply sequential compression devices使用間歇性加壓裝置
- BMaintain proper hip alignment保持正確的髖關節對位
- CEncourage early ambulation as prescribed✓ 正解依指示鼓勵早期下床活動
- DAdminister prophylactic anticoagulants給予預防性抗凝血劑
全髖關節置換術後，深部靜脈血栓（DVT）是肺栓塞的核心前驅因素。早期下床活動能透過肌肉幫浦效應促進血液回流，是預防靜脈血栓形成的黃金標準。雖然抗凝血劑與加壓裝置有效，但活動帶來的生理性血液循環恢復是降低血栓風險的根本核心。
After total hip arthroplasty, deep vein thrombosis (DVT) is the key precursor to pulmonary embolism. Early ambulation uses the muscle pump effect to enhance venous return and is the gold-standard intervention for preventing venous thromboembolism. Although anticoagulants and compression devices are effective, restoring physiologic circulation through movement is the fundamental way to reduce thrombosis risk.
美國醫院有嚴格的物理治療師（PT）團隊共同參與早期下床計畫；台灣則較多由家屬輔助，護理師需確認病人下床耐受度。
