Math review question

Nurses Medications

Published

I am starting a new job and it has been a while since I have done nursing math for a test. I was given this test problem "A patient is to receive a medication at the rate of 4 gm/hr. If 10 gm of this medication is placed in 100 ml of IV solution, how many milliliters per hour will the client receive?" and came up with the correct answer but want to make sure I did it correctly and didn't just stumble across the correct answer. The way I did it was 4000mg/10000mg X 100ml. Is this the correct way to go about this problem?

Thanks

4gm= 1 hr

10gm = 100ml

100ml/10gm X 4gm/1hr = 40ml/hr

You don't have to convert to milligrams at all in this problem. Your on hand dose is in grams and your desired rate is g/hr.

100 mL/10 g = 10mL/1g x 4 g/hr = 40 mL/hr.

dose ordered/dose on hand x ml=

4/10x100x1hr........40ml/hr

was this what you got?

if it were per minute, as in no pump; multiply by 60minutes instead of 1 hr

Thanks for the refresher... its been a while!!
