The nurse is assessing a client who reports pain to the left lower extremity, especially while ambulating. The discomfort is relieved with rest. Assessment findings confirm left lower leg mottling and hairlessness. Which health problem will the nurse most likely include in the planning of the client's care?

A. Peripheral vascular disease: Intermittent claudication, or pain that occurs during ambulation and is relieved by rest, is a hallmark of arterial insufficiency. Mottling and hairlessness are objective signs of chronic tissue ischemia due to reduced peripheral blood flow. These findings indicate that the arterial supply is failing to meet the metabolic demands of the lower extremity. B. Coronary artery disease: This condition involves the narrowing of the arteries supplying the heart muscle, typically presenting as chest pain or angina. While it shares the same underlying atherosclerotic process as peripheral vascular disease, it does not directly cause leg mottling or hairlessness. The client’s specific symptoms are localized to the peripheral rather than the cardiac circulation. C. Right sided heart failure: Right-sided failure primarily manifests as systemic venous congestion, leading to jugular venous distention and dependent edema. It does not typically cause intermittent claudication or the skin changes associated with arterial deprivation. While it affects the lower extremities, it presents with swelling rather than mottling and hair loss. D. Arterial embolism: An acute embolism usually presents with the "six Ps," including sudden, severe pain, pulselessness, and pallor. The client's report of intermittent pain relieved by rest suggests a chronic, progressive narrowing rather than an acute, total occlusion. An embolism is an emergency that would not typically be relieved simply by resting.
