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

Correct Answer is ["600"]
Explanation
- Calculate the infusion rate in mL/minute: 200 mL / 20 minutes = 10 mL/minute - Convert the infusion rate to mL/hour: 10 mL/minute x 60 minutes/hour = 600 mL/hour
- Set the infusion pump to deliver 600 mL/hour
Correct Answer is ["240"]
Explanation
- To prepare the solution, the nurse needs to dilute the enteral nutrition formula with water.
- The formula concentration is 75%, so the water concentration is 25%.
- The total volume of the solution is 320 mL, so the water volume is 25% of 320 mL, which is 80 mL.
- The formula volume is 320 mL - 80 mL, which is 240 mL.
- The nurse should use 240 mL of the enteral nutrition formula and 80 mL of water to prepare the solution.
