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.)
The Correct Answer is ["12000"]
- To calculate the units of heparin in 12 hours, multiply the infusion rate by the concentration of heparin and the duration of infusion.
- Infusion rate = 25 mL/hour
- Concentration of heparin = 20,000 units / 500 mL
- Duration of infusion = 12 hours
- Units of heparin in 12 hours = 25 x (20,000 / 500) x 12
- Units of heparin in 12 hours = 12,000
