Sodium Disturbance Calculations I. Hyponatremia A. Sodium Deficit = amount of sodium required to raise the Pna to the desired level. Sodium Deficit = Vd sodium (L/kg) Body weight (kg) [Desired Pna- Current Pna] Your answer will be in mEq. B. How much sodium-containing solution should be administered to raise the Pna to the desired level? If you know the sodium concentration of the solution: Amount of solution = sodium deficit (mEq)]/sodium concentration (mEq/L) So, you take your answer from part a and divide by the solution’s sodium concentration. Your answer could be in liters or milliliters. C. If you are given the desired rate of correction for the Pna in mEq/L per hour, you can calculate how much time it will take to raise the Pna to the desired level. Time required for correction = (Pna desired – Pna current)/Rate of correction Your answer will be in hours (or in can be minutes depending on the units) D. To calculate the rate of infusion of the solution to correct the sodium to the desired
