A nurse is providing teaching about foot care for a client who has type 2 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

Rationale: A. "I should soak my feet before trimming my nails": Soaking feet can soften the skin but increases the risk of skin breakdown and infection in clients with diabetes. Moist environments can promote fungal growth and make the skin more susceptible to injury when trimming nails. B. "I should use a heating pad at night when my feet feel cold": Using a heating pad is unsafe because diabetic neuropathy can reduce sensation, increasing the risk of burns. Clients with diabetes should avoid direct heat sources on their feet to prevent injury. C. "I should buy new shoes late in the day": Feet tend to swell throughout the day, so purchasing shoes in the late afternoon or evening ensures a better fit. Properly fitting shoes help prevent pressure points, blisters, and ulcers, which are critical for diabetic foot care. D. “I should wear a clean pair of nylon socks every day": Nylon socks do not wick moisture effectively and can trap sweat, increasing the risk of fungal infections. Cotton or moisture-wicking socks are recommended to keep feet dry and reduce the risk of skin breakdown.
