Ati lpn med surg cardiac exam ( 33 Questions)
A nurse is caring for a client with peripheral artery disease who has an arterial ulcer. Which of the following best describes the mechanism for developing the clinical problem?
Swelling of the lower extremity can create a wound that is difficult to heal. Swelling typically relates to venous ulcers, not arterial ulcers, which are caused by reduced blood flow.
Decreased blood flow to the area can cause the wound and decrease the healing. Peripheral artery disease causes decreased blood flow, leading to poor oxygenation and slow healing of arterial ulcers.
Lower extremity compression stockings likely caused the wound to occur. Compression stockings are used in venous insufficiency and do not cause arterial ulcers.
Increased blood sugar associated with the condition is likely the cause of the wound not healing. While high blood sugar can impair healing, decreased blood flow is the primary cause of arterial ulcers in PAD.
