A client with deep vein thrombosis (DVT) is receiving a continuous IV infusion of heparin sodium 20,000 units in 5% dextrose injection 500 mL at the rate of 25 mL/hour. How many units of heparin should the client receive in 12 hours? (Enter numeric value only.)

Calculate the total volume infused over 12 hours: Total volume (mL) = Infusion rate (mL/hour) x Infusion time (hours) = 25 mL/hour x 12 hours = 300 mL Calculate the concentration of heparin in the IV solution: Heparin concentration (units/mL) = Total heparin units / Total volume of solution (mL) = 20,000 units / 500 mL = 40 units/mL Calculate the total units of heparin received in 12 hours: Total heparin units = Heparin concentration (units/mL) x Total volume infused (mL) = 40 units/mL x 300 mL = 12000 units
