下列哪項護理行動最能促進術後病人的靜脈回流？
Which of the following nursing actions best promotes venous return in a post-surgical client?
- AEncouraging early ambulation✓ 正解鼓勵早期下床活動
- BKeeping the bed in a high-Fowler's position保持床鋪在高福勒氏姿勢
- CApplying hot packs to the legs對腿部應用熱敷包
- DRestricting fluid intake限制液體攝取

早期下床活動（Early ambulation）是利用肌肉收縮（肌肉幫浦機制）促進靜脈血液回流的最有效方式，能有效預防術後深層靜脈血栓。熱敷會影響血管舒張調控，且非物理回流機制；高坐位會減緩回流；限水會導致血液黏滯，不利循環。
Early ambulation effectively promotes venous return by utilizing the skeletal muscle pump mechanism, which helps prevent postoperative deep vein thrombosis. Other options such as high-Fowler's positioning, hot packs, or fluid restriction are either ineffective or potentially harmful to circulation.
