Latanya Brown is a nine-year old African American who is hospitalized with acute sickle cell crisis. The pharmacist is preparing intravenous fluids for this patient. She adds 2 grams of potassium chloride to 1 L of D5W/1/2 normal saline. What is the estimated osmolarity per liter (mOsm/L) of this solution assuming the final volume is 1 L (MW of sodium = 23, potassium = 39, chloride = 35.5 and dextrose is 198)?
