護理師照護一位髖關節置換術後病人，下列哪項預防深層靜脈栓塞（DVT）的措施最為優先？
A nurse is caring for a client who is post-operative following a hip arthroplasty. Which intervention is the priority to prevent deep vein thrombosis (DVT)?
- AAdminister prophylactic anticoagulants給予預防性抗凝血劑
- BPerform passive range-of-motion exercises執行被動關節活動度運動
- CApply sequential compression devices (SCDs)應用循序間歇性加壓裝置（SCDs）
- DEncourage early ambulation as ordered✓ 正解鼓勵依指示早期下床活動
髖關節置換術後病人因長期臥床及手術創傷，血液處於高凝狀態，深層靜脈栓塞（DVT）風險極高。護理介入的優先級遵循「安全性」與「生理功能恢復」。雖然抗凝血劑與 SCDs 為常規輔助，但早期下床活動（Early Ambulation）能透過肌肉幫浦效應促進下肢靜脈血液回流，是預防血栓最主動且有效的生理措施。
Clients after hip arthroplasty are at extremely high risk for DVT because of prolonged bed rest and surgical trauma that place the blood in a hypercoagulable state. Nursing priorities follow the principles of 'safety' and 'restoration of physiological function.' Although anticoagulants and SCDs are standard adjuncts, early ambulation is the most active and effective physiological measure for preventing thrombus formation, as it promotes venous return via the skeletal muscle pump.
美國臨床多採用「術後當日或次日（Post-op Day 0 or 1）下床」的快速康復計畫（ERAS），護理師在推動早期活動時需特別注意病人疼痛控制（Pain Management）是否足夠。
