Question

1. You have an order to administer heparin sodium IV at 1000 units per hour. It is supplied by your pharmacy as 25,000 units in 250 mL of D5W. For how many milliliters per hour should you program the pump?

Answer 1

Answer;

Here the given ordered dose is 1000 units per hour
But the available dose is 25,000 units in 250 ml

It shows that 1 ml contain 25,000 / 250 = 100 units.
It means 1 ml of D5W contain 100 units of these drug.

In order to give 1000 units per hour, the total amount would be
1000/100 = 10 ml

So the infusion pump should be set at the rate of 10 ml / hr
