The nurse is instructing the client with chronic kidney disease (CKD) to maintain adequate nutritional intake. Which diet would be most appropriate?

Choice A reason: A low-protein diet can be beneficial in reducing the workload on the kidneys by decreasing the production of waste products that need to be excreted. However, high-potassium intake is not recommended for CKD patients because their kidneys may not efficiently excrete potassium, leading to hyperkalemia, which can be dangerous.Choice B reason: A diet high in calcium, potassium, and protein is not suitable for CKD patients. Excessive protein can increase the production of waste products, calcium intake needs to be monitored to avoid complications like calcification, and high potassium levels can lead to hyperkalemia. This combination could potentially worsen the patient's condition.Choice C reason: A high-carbohydrate, high-protein diet is not ideal for CKD patients. While carbohydrates can provide energy, high protein intake increases the load on the kidneys. The goal is to reduce the production of waste products that the kidneys need to filter, so a high-protein diet is counterproductive.Choice D reason: A low-protein, low-sodium, low-potassium diet is most appropriate for CKD patients. Reducing protein intake decreases the production of waste products, low sodium helps control blood pressure and fluid balance, and low potassium prevents hyperkalemia. This diet helps manage the symptoms and progression of CKD more effectively.
