A nurse is providing preventive education to a client who has diabetes mellitus. Which of the following statements made by the client indicates they understand proper foot care?

Clients with diabetes mellitus are at increased risk for foot complications due to peripheral neuropathy, reduced circulation, and impaired wound healing. Small injuries can go unnoticed and progress to infections or ulcers if proper foot care is not maintained. Preventive education focuses on protecting the feet from trauma, maintaining skin integrity, and promoting safe nail care. Proper daily foot hygiene and inspection are essential components of diabetes self-management. A. Remaining barefoot at home is unsafe for clients with diabetes because it increases the risk of unnoticed injuries, cuts, or burns due to decreased sensation from neuropathy. Protective footwear should be worn at all times to prevent trauma and subsequent infection or ulcer formation. B. Applying lotion between the toes is incorrect because excess moisture in this area can promote fungal growth and skin breakdown. Lotion should be applied to the tops and bottoms of the feet, but not between the toes, to avoid creating a moist environment that encourages infection. C. Filing the edges of toenails after trimming them is correct because it helps prevent sharp nail edges that can cause skin injury or ingrown nails. Proper nail care reduces the risk of trauma and infection, which is especially important in clients with impaired sensation and delayed wound healing. D. Using a heating pad when feet are cold is unsafe for clients with diabetes because reduced sensation increases the risk of burns. Clients may not accurately feel heat intensity, leading to skin damage. Safer alternatives include wearing warm socks or ensuring proper ambient temperature.
