Final answer:
In a patient with PVD, the skin of the lower extremity may appear pale or bluish, and ulcers may develop.
Step-by-step explanation:
In a patient with peripheral vascular disease (PVD), the skin of the lower extremity can show various characteristic changes.
One common symptom is pale or bluish skin, which indicates impaired blood flow. This can occur due to narrowing or blockage of the arteries serving the lower limbs.
Ulcers may also develop on the skin of the lower extremity, particularly on the lower leg or foot. These ulcers are often slow to heal and can be painful.
