1. Determine the concentration of heparin in the solution:
- There are 25,000 units of heparin in 500 mL of D5W.
- Concentration = 25,000 units / 500 mL = 50 units/mL.
2. Calculate the required mL/hr for the desired infusion rate:
- The order is for 1600 units/hr.
- To find the mL/hr:
ML/HR=desired units/hr divided by unts/ml
=1600/50
=32ml/hr
