Which of the following is a characteristic sign of peripheral vascular disease (PVD)?

The characteristic sign of peripheral vascular disease (PVD) is shiny, thin, hairless skin. This condition arises due to decreased blood flow to the extremities as a result of narrowed or blocked blood vessels. When the blood supply is insufficient, the skin may lose its normal texture and hair growth, leading to a shiny appearance and thinning. Additionally, inadequate blood flow can contribute to ulcers or other skin issues, further underscoring the importance of recognizing this skin change as a symptom of PVD.

Other options, such as enlarged lymph nodes and a pulsating abdominal mass, relate more to conditions involving the lymphatic system or abdominal aorta aneurysms, respectively, rather than peripheral vascular disease. High blood pressure, while a risk factor for PVD, is not a specific indicator of the disease itself. Thus, recognizing the specific skin changes is essential in identifying and managing PVD effectively.
