護理師照護一位剛完成人工髖關節置換術的病人。哪項措施能最有效地降低深層靜脈血栓的風險？
A nurse is caring for a client with a fresh postoperative hip replacement. Which intervention is most effective in reducing the risk of deep vein thrombosis?
- AApplying warm compresses to the calf area在小腿部位敷熱敷包
- BAdministering oral aspirin every 6 hours每6小時給予口服阿斯匹靈
- CEncouraging early ambulation✓ 正解鼓勵早期下床活動
- DMaintaining strict bed rest for 48 hours嚴格卧床休息48小時
深層靜脈血栓（Deep Vein Thrombosis, DVT）的預防核心在於促進血液循環與減少靜脈淤滯。術後早期活動利用小腿肌肉收縮產生的「肌肉泵浦（Muscle pump）」效應，能有效推動靜脈血液回流至心臟，是預防血栓最有效的非藥物措施。絕對臥床會導致血液淤積，增加血栓形成的風險。熱敷無法預防血栓，反而可能因血管擴張導致傷口滲血或燙傷，且阿斯匹靈並非預防術後 DVT 的常規首選藥物。
The core of deep vein thrombosis (DVT) prevention lies in promoting blood circulation and reducing venous stasis. Early postoperative ambulation uses the muscle pump effect produced by calf muscle contractions to effectively propel venous blood back toward the heart, making it the most effective non-pharmacological measure for preventing thrombosis. Strict bed rest leads to blood stasis and increases the risk of clot formation. Warm compresses cannot prevent thrombosis and may, through vasodilation, cause wound oozing or burns; aspirin is also not the standard first-choice agent for postoperative DVT prophylaxis.
