# DOSAGE COMP QUESTION! Need help!

Hello,

Was hoping someone could answer this question for me.

Doctor gives you loading dose of oxytocin 4g in 20 min. You have 40g in 1L . How many ml/hr?

I'll give it a try since I have to redo my HESI. Apparently the exam sections are school specific (Why won't they let me take all the sections and the program can choose which ones they want to apply?!) Argh, anyways I think it's:

333?

convert 1l to 1000ml = 40g/1000ml = 4g/100ml

For every 100ml there is 4g, you have to administer 4 grams in 1/3 hour

20min= 1/3hr=.3hr

100ml/4g x 4g/.3hr = grams cancel = 100ml/.3hr= 333ml/hr

333 ml/hr

Update me if this answer is right (I am not in nursing school yet so I'm not sure if this is out of my league/a calculation I don't know a formula for)

ah 300 ml/hr, not 333

Is your instructor using random drug names for these problems or did you misread the problem. Oxytocin is administered in milliunits. For induction of labor: Initial dose: 0.5 to 1 milliunits/minute via IV infusion.

Maybe a L&D nurse can provide some input, but 4g of Oxytocin is a weird order.
