The nurse is providing discharge teaching to a patient with peripheral arterial disease. Which statement by the patient requires the nurse to re-educate the patient?

Choice A rationale Smoking cessation is a critical instruction for a client with peripheral arterial disease (PAD). Nicotine is a potent vasoconstrictor that significantly reduces blood flow to the extremities and directly damages the arterial lining, accelerating the progression of atherosclerosis and worsening symptoms like claudication, so this statement is correct. Choice B rationale This statement indicates a need for re-education because the use of direct heat, such as a heating pad, is strictly contraindicated for clients with PAD. Their compromised circulation prevents them from accurately sensing high temperatures, increasing the risk for severe burns before they can feel the damage, which can lead to open wounds or ulcers. Choice C rationale A supervised or structured walking program is one of the most effective non-pharmacological treatments for mild to moderate PAD. Regular exercise improves collateral circulation (angiogenesis) around the narrowed arteries, helping to reduce the symptoms of intermittent claudication and improving the client's functional capacity, so this statement is correct. Choice D rationale Clients with PAD must avoid anything that constricts blood flow to their legs and feet, including tight socks, compression stockings (unless specifically prescribed), and restrictive shoes. These items can further impede the already compromised arterial circulation, worsening ischemia, which makes this a correct and appropriate statement.
