護理師照顧有深層靜脈栓塞（DVT）病史的病人，哪項預防指導最重要？
A nurse is caring for a client with a history of DVTs. Which instruction is crucial for prevention?
- ADiscourage hydration to reduce bathroom trips為減少如廁次數而 discouraging 水分攝取
- BSuggest wearing tight socks that bunch up建議穿著會捲起堆疊的緊身襪
- CAdvise sitting for long hours建議長時間久坐
- DEncourage frequent ambulation✓ 正解鼓勵頻繁行走
深層靜脈栓塞（DVT）的高風險病人，預防的核心在於促進靜脈血液回流，避免血液淤積形成血栓。早期且規律的下床活動（Ambulation）能透過小腿肌肉幫浦（Muscle pump）機制，有效促進血液回流。此外，應避免久坐、保持適當的水分攝取以避免血液濃縮，以及正確穿戴彈性襪，這些皆為臨床預防 DVT 的重要護理指導。
For clients at high risk of deep vein thrombosis (DVT), the core of prevention is promoting venous return and avoiding blood stasis that leads to thrombus formation. Early and regular ambulation effectively promotes venous return through the calf muscle pump. In addition, prolonged sitting should be avoided, adequate hydration should be maintained to prevent hemoconcentration, and elastic stockings should be worn correctly; all are important clinical nursing instructions for DVT prevention.
