護理師指導一位周邊動脈疾病（PAD）病人。下列哪項敘述顯示病人已理解自我照護原則？
A nurse is teaching a client who has peripheral arterial disease (PAD). Which of the following statements by the client indicates an understanding of self-care?
- AI will use a heating pad on my feet at night我晚上會在腳上使用熱敷墊
- BI will elevate my legs above the heart level我會將腿部抬高至高於心臟水平
- CI should wear tight-fitting socks for compression我應該穿著緊身襦以進行加壓
- DI will avoid crossing my legs when sitting✓ 正解我坐著時會避免翹腳
周邊動脈疾病（PAD）的病理特徵是動脈血流灌流不足。病人的照護重點在於「促進血液循環」與「保護患肢」。交叉雙腿（Crossing legs）會機械性壓迫血管，進一步阻礙血液流向遠端肢體，因此必須避免。此外，PAD 病人常伴隨感覺遲鈍，故應避免熱敷以免燙傷，且應避免抬高雙腿，因為這會對動脈血流造成額外的重力阻力。
The pathological hallmark of peripheral arterial disease (PAD) is inadequate arterial blood flow. The focus of care is to 'promote circulation' and 'protect the affected limb.' Crossing the legs mechanically compresses blood vessels and further impedes distal blood flow, and must therefore be avoided. In addition, clients with PAD often have decreased sensation, so heat application should be avoided to prevent burns; leg elevation should also be avoided, as it adds gravitational resistance to arterial flow.
