calculation problem

calculation question...

IV 500ml d5w with 25,000 units heparin infusing at 30ml/hr. How many units are infusing per hour?

First, find out how many units are in 1 mL. You do that by dividing 25,000 by 500. So 50 units are in 1 mL.

So if there are 50 units in 1 mL, multiple that by 30 (that's how many mL's per hour) and you will find your answer.

There is 25,000 units per 500 ml = 50 units/ml

50 units/ml * 30 ml/hr = 1,500 units/hr

Anyone else come up with a similar answer?

You have to figure out how many units/mL you have:

25,000U/ 500mL = 50 units/mL

then take that times the rate

50 U/mL * 30mL/hr= 1500 U/hr

The ML cancel...thus you get 1500 U/hr....
