A nurse is teaching a client who has diabetes mellitus about foot care. Which of the following instructions should the nurse include?

Rationale: A. "Wear loose-fitting slippers around the house.": While wearing slippers can protect the feet from trauma, loose-fitting slippers can increase the risk of friction, blisters, or slipping. Well-fitting, supportive footwear that cushions the feet and prevents injury is preferred for clients with diabetes, as minor injuries can lead to ulcers or infections. B. "Use a heating pad to keep your feet warm at night.": Heating pads pose a burn risk for clients with diabetic neuropathy who have reduced sensation. Nerve damage can prevent the client from perceiving excessive heat, potentially causing burns or tissue injury. Safer alternatives include warm socks or warm water for brief periods with careful temperature control. C. "Wear cotton rather than nylon socks.": Cotton socks are breathable, absorb moisture, and reduce friction, which helps prevent skin breakdown and fungal infections. Nylon or synthetic socks may retain sweat, increase moisture, and contribute to skin maceration or fungal growth. Proper sock choice supports foot hygiene and reduces risk of complications in diabetic clients. D. "Wash your feet twice per day with antibacterial soap and hot water.": Daily foot hygiene is important, but using hot water can scald the skin, especially in clients with neuropathy who cannot accurately sense temperature. Mild soap and lukewarm water are recommended. Excessive washing with antibacterial soap may also dry out the skin and increase susceptibility to cracks and infection.
