The nurse is providing health promotion teaching to a patient with chronic kidney failure who has started hemodialysis. Which of the following statements by the patient demonstrates a correct understanding?

A. "I've made a list of high-phosphate foods to avoid.": In chronic kidney disease (CKD), phosphate excretion is impaired, leading to hyperphosphatemia, which can cause bone demineralization and cardiovascular complications. Avoiding high-phosphate foods such as dairy, nuts, and processed foods demonstrates understanding of dietary management. B. "I'm going to try a high-protein, low carbohydrate diet.": While some protein is necessary to prevent malnutrition in hemodialysis patients, indiscriminate high-protein intake can increase phosphorus and nitrogenous waste accumulation, which dialysis may not fully remove, potentially worsening uremia. A balanced approach guided by a renal dietitian is essential. C. "I'm making a point of trying to eat lots of bananas and other food rich in potassium.": CKD patients on hemodialysis are at high risk for hyperkalemia due to reduced renal excretion. Consuming potassium-rich foods like bananas can lead to dangerous cardiac arrhythmias, so this indicates a misunderstanding of dietary restrictions. D. "I don't think I've been drinking enough, so I want to include 10 to 12 glasses of water each day.": Fluid intake in hemodialysis patients must be carefully regulated because fluid overload can cause hypertension, pulmonary edema, and heart failure. Excessive intake demonstrates a lack of understanding of fluid restrictions necessary between dialysis sessions.
