Question

a nurse is providing dietary teaching to a client who has nephropathy secondary to diabetes mellitus. which of the following instructions should the nurse include?

eat no more than 300 mg of cholesterol per day.
consume less than 45% of total calories from carbohydrates per day.
consume less than 0.8 g/kg of body weight of protein per day.
eat at least 45 g of fiber per day.

Explanation:

Analyze the client's condition

The question describes a client with nephropathy secondary to diabetes mellitus (diabetic nephropathy). Diabetic nephropathy is a progressive kidney disease caused by damage to the capillaries in the kidneys' glomeruli due to long-standing diabetes. Managing dietary intake, particularly protein, is crucial to slow the progression of renal damage.

Evaluate protein intake recommendations

In patients with diabetic nephropathy, high protein intake can increase intraglomerular pressure and accelerate the decline in glomerular filtration rate (GFR). Clinical guidelines (such as those from the American Diabetes Association and the National Kidney Foundation) recommend a moderate restriction of dietary protein to slow the progression of kidney disease. The recommended daily protein intake for individuals with diabetic nephropathy who are not on dialysis is typically restricted to approximately \(0.8\text{ g/kg}\) of body weight per day. Therefore, instructing the client to consume less than \(0.8\text{ g/kg}\) of body weight of protein per day is the correct intervention.

Evaluate the other dietary options

• Cholesterol intake: Guidelines generally recommend limiting cholesterol intake to less than \(200\text{ mg/day}\) (rather than \(300\text{ mg/day}\)) for individuals with diabetes and cardiovascular risk factors or renal disease to manage dyslipidemia.
• Carbohydrate intake: Carbohydrates should typically make up \(45\%\) to \(65\%\) of total daily caloric intake. Restricting carbohydrates to less than \(45\%\) is not a standard recommendation for diabetic nephropathy and could lead to inadequate energy intake or excessive fat/protein consumption.
• Fiber intake: The recommended daily fiber intake for adults is generally \(25\text{ g}\) to \(30\text{ g}\) per day (or \(14\text{ g}\) per \(1,000\text{ kcal}\)). Consuming at least \(45\text{ g}\) of fiber per day is excessively high and can cause gastrointestinal distress.

Answer:

• Eat no more than 300 mg of cholesterol per day.
• Consume less than 45% of total calories from carbohydrates per day.
• Consume less than 0.8 g/kg of body weight of protein per day. (Correct answer)
• Eat at least 45 g of fiber per day.
