A patient is receiving Dextrose 5% in 0.45% Sodium Chloride Injection and 40 mEq of potassium chloride in a total volume of 1000 mL through an IV set that delivers 15 drops per ml. The IV fluid has been running at a rate of 12 drops per minute for 15 hours. Molec Weights: Dextrose = 180, Na = 23, K = 39, CI = 35.5 1. How many mEq of potassium chloride have been administered so far? K = 39; Cl = 35.5; Na = 23; Dextrose = 180 II. How many grams of KCl have been administered over the 15 hour period? III. How many millimoles of KCl have been administered over the 15 hour period? IV. What is the total osmolarity of the IV fluid being administered? Express your answer as milliosmoles, rounded to the nearest whole number, per 1000 ml.
