When caring for a patient who has intermittent claudication, nurse advises the patient to

Correct option is D

In intermittent claudication, caused by peripheral arterial disease (PAD), regular walking promotes collateral circulation and improves blood flow. Walking until pain starts, resting, and then walking again is a therapeutic strategy. Explanation of each option: • (a) Apply graduated compression stockings – These are used for venous disorders like varicose veins, not arterial insufficiency like intermittent claudication. • (b) Elevate the legs when sitting – Elevating legs may reduce arterial blood flow in PAD and worsen symptoms. It’s suitable for venous insufficiency, not arterial. • (c) Refrain from vigorous exercise – While excessive strain is not advised, regular walking is part of the treatment plan and improves function. • (d) Walk as much as tolerated – Correct. Graded walking exercises improve muscle oxygenation and reduce symptoms over time through collateral circulation.
