Final answer:
To administer fluids via the Parkland formula, an IV bag of sterile solution is diluted with a stock solution, such as KCl, using a dilution calculation to ensure proper concentration for hydration correction.
Step-by-step explanation:
To administer fluids using the Parkland formula, the aide must make a proper solution by diluting a stock solution, such as potassium chloride (KCl), into an IV bag of sterile solution. The aid uses a syringe to draw up the stock solution and injects it into the IV bag to achieve the desired concentration. The aide must perform a dilution calculation to ensure the correct concentrations and volumes are used, following the formula C1V1 = C2V2, with all units matching.
For dehydration correction, ordinary NaCl or a mixture of 2/3 isotonic saline and 1/3 Na lactate is recommended, depending on the fluid and electrolyte loss characteristics of the patient. Parenteral administration of these solutions is critical in repairing the losses experienced by the dehydrated patient.
Caution: To avoid errors in the dilution process, ensure that the concentrations and volumes are in the same units before using the formula. If not, convert them to the same units first.
