A nurse is reinforcing teaching about foot care with a client who has diabetes mellitus. Which of the following statements should the nurse identify as indicating the client understands the teaching?

The scenario requires validating educational outcomes regarding diabetic foot care. Knowledge of peripheral neuropathy, vascular complications, and prophylactic skin hygiene must be applied to distinguish safe self-care habits from harmful practices that cause ulceration. Choice A rationale Cutting toenails straight across prevents the development of ingrown nails, which can breach the skin barrier. This prevents localized infections that progress rapidly to severe ulcerations due to diabetic microvascular disease. Choice B rationale Prolonged soaking causes tissue maceration, skin breakdown, and bacterial entry points. Normal skin integrity requires washing with mild soap and drying thoroughly, rather than exposing the feet to prolonged moisture. Choice C rationale Nylon socks trap moisture and increase friction against delicate skin, promoting blisters and fungal growth. Breathable cotton or wool socks are required to keep feet dry and cushion bony prominences. Choice D rationale Applying lotion between the toes creates a moist environment that encourages fungal infections like tinea pedis. Moisture accumulates naturally in interdigital spaces, requiring them to be kept dry.
