Isotonic Saline is the prototype crystalloid fluid. 0.9% NaCl or normal saline. Lactated Ringers contains potassium and calcium. Fluid Replacement Standard Orders: Normal Saline or 0.9% NaCl at 20 mL / kg Followed by Dextrose 5% in 0.45 normal saline Followed by Dextrose 5% in 0.45 normal saline with 20 mEq KCL per 1000 mL Potassium is only added to the IV when there is documentation of voiding. Nursing Interventions Assess child’s hydration status Accurate intake and output Daily weights most accurate way to monitor fluid levels Hourly monitoring of IV rate and site of infusion. Increase fluids if increase in vomiting or diarrhea. Decrease fluids when taking po fluids or signs of edema.
