A home health nurse is teaching a client who has a new diagnosis of diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

A. Clients with diabetes should maintain adequate hydration, especially if hyperglycemia causes polyuria. Limiting fluid intake could worsen dehydration and increase blood glucose levels. B. Insulin timing relative to meals is important, but exercise can increase the risk of hypoglycemia if insulin is administered immediately prior. Exercise planning should include monitoring blood glucose and adjusting insulin or carbohydrate intake, not arbitrarily taking insulin 30 minutes before activity. C. A low-residue diet (low fiber) is not indicated for diabetes management. Clients are encouraged to eat a balanced diet with complex carbohydrates and fiber to help control blood glucose. D. Clients with diabetes are at high risk for neuropathy and peripheral vascular disease, which can lead to foot ulcers and infections. Daily inspection of the feet, including using a mirror to view the soles and areas that are hard to see, is a critical preventive measure to identify cuts, blisters, redness, or infections early. Proper foot care reduces the risk of serious complications.
