護理師指導病人預防深部靜脈栓塞（DVT），下列哪項陳述顯示病人已理解衛教內容？
A nurse is teaching a client about the prevention of deep vein thrombosis (DVT). Which client statement indicates an understanding of the teaching?
- AI should cross my legs while sitting to improve circulation坐著時交叉雙腿以促進循環
- BI will remain in bed until my legs feel strong我會留在床上直到我的腿感覺有力為止
- CI will wear tight-fitting socks to keep my legs warm我會穿著緊身襪以保持腿部溫暖
- DI will avoid using pillows under my knees✓ 正解我會避免在膝蓋下使用枕頭
預防 DVT 的重點在於促進靜脈回流。膝蓋下方放枕頭會壓迫膕窩血管，阻礙回流，增加栓塞風險，因此應避免。穿著過緊的襪子反而會造成壓迫導致循環變差，坐姿交叉雙腿亦同。適度運動與早期下床活動是促進血液循環的最佳方式，而非臥床。
DVT prevention focuses on promoting venous return. Placing a pillow under the knees compresses the popliteal vessels, obstructs venous return, and increases the risk of thrombosis; this practice should be avoided. Wearing tight socks can compress the leg and worsen circulation, and crossing the legs while sitting has the same effect. Moderate exercise and early ambulation are the best ways to promote circulation, not bed rest.
美國護理極強調 DVT 預防的階梯式措施（機械式與藥物）；台灣醫療環境對於 DVT 預防的術後衛教強調程度亦高，但藥物使用比例可能隨醫院政策不同。
