預防長途旅行引起的 DVT 應避免血液淤積。活動腳踝（A）與定期起身走動（E）能促進小腿肌肉幫浦功能，加速靜脈回流。水分攝取（C）有助於預防血液濃縮。錯誤選項 B 中，緊身衣物會阻礙回流；D 中，久坐是 DVT 的高風險因子，應鼓勵間歇活動。
Performing ankle exercises, walking regularly, and maintaining hydration help promote venous return and prevent blood stasis and viscosity changes associated with prolonged immobility. Wearing tight clothing or remaining seated without movement increases the risk of deep vein thrombosis by restricting circulation.
✦ 台美臨床差異
美國護理師常提供長途旅行衛教單張，強調 DVT 風險；台灣臨床較少於一般衛教中主動提及此預防策略。
