A nurse is providing teaching about foot care to a client who has diabetes mellitus. Which of the following instructions should the nurse include? (Select all that apply.)

Washing feet daily with warm water and soap maintains hygiene and prevents infection. Alternating shoes prevents pressure sores and allows shoes to dry. Soaking feet can cause skin breakdown and maceration. Open-toe shoes leave the feet vulnerable to injury. Natural fiber socks (cotton or wool) are preferred over synthetic fabrics as they absorb moisture better.
