Total units of heparin in the bag = 35,000 units Total volume in the bag = 500 ml Infusion rate = 25 ml/hr First, calculate the units of heparin per milliliter: Units of heparin per milliliter = 35,000 units / 500 ml = 70 units/ml Now, you can calculate the units of heparin infused per hour: Units of heparin per hour = Units of heparin per milliliter × Infusion rate. Units of heparin per hour = 70 units/ml × 25 ml/hr = 1,750 units/hr So, 1,750 units of heparin will be infused per hour.
