一位接受全髖關節置換術後兩天的病患，下列哪項護理措施對預防生理併發症至關重要？
A nurse is caring for a client who is 2 days postoperative following a total hip arthroplasty. Which intervention is essential to prevent physiological complications?
- AMaintain the client in a side-lying position with a pillow between the legs讓病人保持側臥位，雙腿之間放置枕頭
- BEncourage the client to remain in bed to protect the incision鼓勵病人留在床上以保護切口
- CPerform passive range of motion exercises on the affected hip對患側髖關節進行被動關節活動度運動
- DAdminister prophylactic anticoagulants as ordered✓ 正解依醫囑給予預防性抗凝血藥物
髖關節置換術後最危險的併發症之一是深層靜脈血栓（DVT）及其引發的肺栓塞。術後早期給予抗凝血劑（如 Enoxaparin 或 Warfarin）配合早期下床活動，是預防血栓形成的最重要標準流程。長期臥床反而會增加血流淤滯風險，而 passive ROM 運動並不適合術後急性期的關節保護。
One of the most dangerous complications after total hip arthroplasty is deep vein thrombosis (DVT) and its sequela, pulmonary embolism. Early postoperative anticoagulation (e.g., enoxaparin or warfarin) combined with early ambulation is the most important standard practice for preventing thrombus formation. Prolonged bed rest actually increases venous stasis risk, and passive ROM is not appropriate for the acute postoperative joint.
美式護理強調護理師在確認醫囑後主動執行抗凝血劑給藥，台式醫療較仰賴醫師確認凝血指數後再調整劑量。
