Answer

The potassium requirement should be individualized depending on the serum potassium levels. Approximately 1600-2400 mg of potassium can be given.

Close watch should be kept on the potassium levels, and modifications can be made accordingly. Hyperkalemia may occur due to excessive intake of high-potassium foods, catabolism, and other causes. Leaching of pulses and vegetables should be suggested if the child is hyperkalemic.

Special attention should be given if the child is anuric.

Daily bowel movements are important, because the gastrointestinal route accounts for as much as 30% of potassium excretion in patients with chronic renal failure.
