護理師評估一位周邊動脈疾病（PAD）的病人，預期會發現下列哪些狀況？（選所有適合的）
A nurse is performing an assessment on a client with peripheral artery disease (PAD). Which findings are expected? (Select all that apply.)
- AIntermittent claudication✓ 正解間歇性跛行
- BThick, brittle nails✓ 正解指甲增厚、易碎
- CWarm, flushed extremities四肢溫暖、潮紅
- DLoss of hair on the lower extremities✓ 正解下肢脫毛
- EEdema in the ankles踝部水腫
周邊動脈疾病（PAD）的病理基礎是動脈粥狀硬化導致血管狹窄、灌流不足。臨床表現包括：運動時因缺氧導致的肌肉疼痛（間歇性跛行）；皮膚因長期缺氧變得乾燥、脫毛、趾甲變厚且脆弱；觸診時肢體溫度偏低、脈搏減弱。水腫通常是靜脈回流障礙（如 PVD）的特徵，而非動脈缺血的直接表現。潮紅則是發炎或血管擴張的徵象，與動脈閉塞造成的蒼白或發紺相反。
The pathologic basis of peripheral arterial disease (PAD) is atherosclerosis that narrows arteries and impairs perfusion. Clinical findings include muscle pain on exertion due to ischemia (intermittent claudication); dry, hairless skin with thickened, brittle nails from chronic hypoxia; and cool limbs with diminished pulses on palpation. Edema is characteristic of impaired venous return (such as PVD), not of arterial ischemia. Flushing is a sign of inflammation or vasodilation, opposite to the pallor or cyanosis caused by arterial occlusion.
