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 ["12","000\u00a0"]
- 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 ["200 mL\/hour"]
Explanation
- To calculate the infusion rate, divide the volume of the solution by the infusion time in hours: 500 mg/100 mL / 0.5 hour = 200 mL/hour
- The nurse should program the infusion pump to deliver 200 mL/hour of daptomycin solution
- The answer is 200 (mL/hour)
Correct Answer is ["45 microdrops\/minute"]
Explanation
- Calculate the hourly volume in mL: 45 mL/hour
- Convert the hourly volume to minute volume: 45 mL/hour ÷ 60 minutes/hour = 0.75 mL/minute
- Multiply the minute volume by the drop factor: 0.75 mL/minute x 60 microdrops/mL = 45 microdrops/minute
- The nurse should regulate the infusion at 45 microdrops/minute
