Which dietary modification would the nurse implement for a client with end stage renal failure?

A. Increase potassium: Clients with end-stage renal failure are at high risk for hyperkalemia because the kidneys cannot adequately excrete potassium. Increasing potassium intake could lead to dangerous cardiac arrhythmias, potassium intake is usually restricted, not increased. B. Decrease calcium: Calcium levels are often low in end-stage renal failure due to impaired vitamin D activation, so calcium intake is generally monitored and supplemented as needed rather than decreased. Restricting calcium without indication can worsen bone disease associated with renal failure. C. Decrease protein: In end-stage renal failure, reducing protein intake helps decrease the accumulation of nitrogenous waste products, such as urea and creatinine, which the failing kidneys cannot excrete efficiently. Protein restriction must be balanced to prevent malnutrition while minimizing further kidney damage. D. Increase phosphate: Clients with renal failure typically develop hyperphosphatemia because phosphate excretion is impaired. Increasing phosphate intake could worsen mineral and bone disorders, phosphate intake is usually restricted rather than increased.
