Which of the following are true regarding potassium supplementation in pediatric IV fluids? Select all that apply.
Explanation & Rationale
Choice A reason: Potassium is not always added to maintenance fluids. It must be individualized based on renal function, serum potassium levels, and clinical condition. Automatic inclusion without assessment can be dangerous. Choice B reason: Potassium supplementation is appropriate when kidney function is confirmed to be normal. Impaired renal function can lead to hyperkalemia, so renal clearance must be verified before adding potassium. Choice C reason: For children weighing ≥10 kg, typical potassium concentrations in maintenance fluids range from 10–20 mEq/L. This range supports physiological needs while minimizing risk of electrolyte imbalance. Choice D reason: For children <10 kg, a lower concentration of 10 mEq/L is generally used. This accounts for smaller body mass and renal maturity, ensuring safe and effective supplementation. Choice E reason: Potassium may be added even if serum levels are normal, provided renal function is intact and the child is receiving maintenance fluids. It is not restricted only to cases of hypokalemia.
