A client is scheduled for surgery. The nurse should explain that the primary purpose of early ambulation post-operatively is to:
- ADecrease the amount of pain medication needed減少所需止痛藥的用量
- BImprove the client's nutritional status改善病人的營養狀況
- CIncrease the client's self-esteem提升病人的自尊
- DPromote venous return and prevent DVT✓ 正解促進靜脈回流並預防深層靜脈血栓

術後早期下床活動（Early ambulation）是預防術後併發症的關鍵措施。術後病人因長期臥床、脫水與手術壓力，血液黏稠度增加，極易發生深層靜脈栓塞（DVT）。活動時，小腿肌肉的收縮能發揮「肌肉幫浦（Muscle pump）」作用，促進靜脈血回流至心臟，從而預防栓塞形成。這是術後護理中確保生命安全層級最高的行動之一。
The primary purpose of early postoperative ambulation is to promote venous return and prevent deep vein thrombosis (DVT). Movement activates the skeletal muscle pump, which facilitates blood flow back to the heart and reduces the risk of clot formation associated with immobility. While other benefits exist, preventing life-threatening complications like DVT is the highest priority.
