While assessing the legs of an adult client, the nurse observes leathery-looking skin. The client reports aching, tired legs that swell if standing for long periods of time. To screen for venous insufficiency, the nurse should ask the client if they have experienced which subjective finding?

A. Cool, pale skin below the knees. This suggests arterial insufficiency rather than venous insufficiency. B. Deep, continuous pain in the calf muscles. This suggests deep vein thrombosis (DVT) rather than chronic venous insufficiency. C. Decreased pain when legs are elevated. This is the best choice as elevation typically relieves symptoms of venous insufficiency by reducing venous pressure. D. Painful symptoms alleviated by warmth. This is less specific to venous insufficiency and more indicative of muscle or joint issues.
