A nurse is providing teaching to a client who has diabetes mellitus. Which of the following instructions should the nurse provide to the client to help prevent the development of nephropathy?

Rationale: A. Controlling hypertension: Controlling hypertension is a key strategy in preventing diabetic nephropathy. High blood pressure can damage the blood vessels in the kidneys, leading to nephropathy. Strict blood pressure control is crucial for kidney protection in clients with diabetes. B. Limiting protein intake: Limiting protein intake may be beneficial for individuals with advanced kidney disease, but it is not a primary prevention strategy for nephropathy in clients with diabetes. Early prevention focuses more on blood sugar and blood pressure control. C. Voiding every 2 hr: Frequent urination or maintaining a specific voiding schedule is not a primary method for preventing nephropathy. The focus should be on managing blood glucose and blood pressure to prevent kidney damage over time. D. Decreasing potassium intake: Decreasing potassium intake is generally not a necessary measure for preventing nephropathy unless kidney function is impaired.
