護理師評估一位周邊動脈疾病（PAD）的病人，下列哪項發現需要優先回報醫師？
A nurse is assessing a client with peripheral artery disease (PAD). Which finding is a priority to report to the provider?
- AThin, shiny skin on the lower legs小腿皮膚變薄且光亮
- BAbsence of pedal pulses in the affected extremity✓ 正解患肢足背脈搏消失
- CIntermittent claudication during walking行走時出現間歇性跛行
- DDependent rubor when the leg is lowered腿部下垂時呈現依賴性紅斑
— Explanation · 中文詳解 —
周邊動脈疾病雖會出現間歇性跛行、皮膚變薄等慢性症狀，但「足背動脈搏動消失」代表急性缺血或血流完全中斷，這是血管急症，若不及時處置可能導致肢體壞死。其餘選項屬於常見的慢性進程，雖需持續追蹤，但不及脈搏消失危急。
While thin skin and claudication are chronic signs of peripheral artery disease, the absence of pedal pulses indicates acute limb ischemia, which is a medical emergency requiring immediate intervention to prevent tissue necrosis.
✦ 台美臨床差異
美台對於 PAD 評估重點一致，美國護理師對動脈缺血的警覺性教育訓練較為強調「6P」原則。
