When discussing foot care with a client with diabetes mellitus, which statement indicates that further teaching is required?

The statement indicating that further teaching is required is about ensuring that flip flops are made of leather. While it's important for individuals with diabetes to wear appropriate footwear to prevent injury, the type of material is not as critical as the overall construction and fit of the footwear. Flip flops, in general, can increase the risk of foot injuries due to their lack of support and protection, regardless of the material they are made of.

Individuals with diabetes should ideally wear closed-toe shoes that provide adequate support and cushioning to prevent foot complications, including ulcers and infections. Therefore, choosing flip flops, whether made of leather or not, is not advisable. It is crucial to emphasize the importance of proper footwear that protects the foot and supports overall foot health rather than focusing solely on material.

The other statements demonstrate an understanding of appropriate foot care for individuals with diabetes. Applying lanolin helps to maintain skin moisture and prevent cracks, avoiding direct application of heating pads protects against burns, and testing the water temperature with a thermometer ensures that the water is comfortable and not too hot, thereby preventing thermal injuries.
