This recommendation helps prevent foot injuries and infections, which are common concerns for individuals with diabetes.

Choice C, using a heating pad, can lead to burns or skin damage if the temperature is not carefully monitored, making it an unsafe practice.

Choice C is incorrect as while facilitating communication is important, it is not the sole responsibility of the nurse manager. Choice D is incorrect as providing training and support for conflict management is part of the role, but the primary responsibility lies in addressing the sources of conflict directly.
