A patient who has had progressive chronic kidney disease (CKD) for several years has just begun regular hemodialysis. Which information about diet will the nurse include in patient teaching?

A. More protein is allowed because urea and creatinine are removed by dialysis: Hemodialysis removes nitrogenous waste products, allowing patients to tolerate a higher protein intake than before dialysis. Adequate protein supports tissue repair and prevents malnutrition, which is common in CKD patients. B. Dietary potassium is not restricted because the level is normalized by dialysis: Potassium intake still needs monitoring, as hyperkalemia can occur between dialysis sessions. Dialysis does not completely prevent dangerous fluctuations in serum potassium. C. Unlimited fluids are allowed because retained fluid is removed during dialysis: Fluid intake must still be controlled because excessive consumption can lead to weight gain, hypertension, and edema between dialysis sessions. D. Increased calories are needed because glucose is lost during hemodialysis: Hemodialysis may result in minimal glucose loss, but the primary dietary focus is on adequate protein intake. Caloric intake should meet overall nutritional needs but is not primarily adjusted.
