Rn Hesi Med Surg Dosage Calculations ( 55 Questions)
A client with deep vein thrombosis (DVT) is receiving a continuous 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.)
To calculate how many units of heparin a client with DVT should receive in 12 hours, the nurse should know the infusion rate and the concentration of heparin. The infusion rate is 25 mL/hour and the concentration of heparin is 20,000 units in 500 mL of solution. To calculate the amount of heparin in one hour, multiply the infusion rate by the concentration and divide by the volume of solution. For example, (25 mL/hour x 20,000 units) / 500 mL = 1000 units/hour. To calculate the amount of heparin in 12 hours, multiply the hourly amount by 12. For example, 1000 units/hour x 12 hours = 12,000 units. Therefore, the client should receive 12,000 units of heparin in 12 hours.
