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

A. "I will soak my feet in warm water every night.": Soaking feet can lead to skin maceration and increase the risk of infection, particularly in clients with diabetes who may have peripheral neuropathy or impaired circulation. Safe foot care recommends washing and gently drying feet without prolonged soaking. B. "I will apply a moisturizing cream between my toes.": Applying moisturizer between the toes can create a moist environment that promotes fungal infections. Moisturizing should be limited to dry areas of the feet, avoiding skin folds and interdigital spaces. C. "I will be sure to wear cotton socks.": Cotton socks help absorb moisture, reduce friction, and prevent excessive sweating, which lowers the risk of skin breakdown and infection. Proper sock choice is a key component of daily diabetic foot care and protects against ulcer formation. D. "I will buy new shoes in the early morning hours.": Feet typically swell during the day, so shoes should be purchased later in the day when feet are at their largest. Buying shoes in the morning may result in footwear that is too tight and increases the risk of pressure sores or blisters.
