# Calculation - page 3

Guys i really do not understand how to do this. The physician orders Pronestyl at 1 mg/min. Solution avail. is 1gm in 500cc D5W. What rate shoud it run if drip factor is 60 gtt/mL. I know... Read More

If I was belittleing you... I would have said Idiot, Dummy, Moron... So relax dude!

Looks like SMS blew this outta proportion... must be why he likes using proportions so much!
and you were belittling me, it's called being passive aggressive. but i'll end argument now... it's sad that you got offended because you were not thanked over a response. that says a lot about a person's character or lack (and yes, a lot is two words not one). i will agree that i did blow some of this out of proportion but you did as well. i sincerely hope that one day you can learn to play nice, that is genuinely nice, with others.

you all have a good night. redneckrn2b, good luck on your test, i'm sure you'll do fine.
2. Thanks! One of these days i will be an RN. I just have to keep that in my mind. The final goal....only 6 months away....

Angie, we must have been typing at the very same time, because when I was doing my orginal answer, there were no other posts showing up, so I figured I would put my new found knowlege that was less than a week old to some good use! LOL I start clinical in the begining of January, so I am trying to get my mental ducks in order now. And yes I know who Rodney Dangerfield is.
Thank you... I was starting to feel OLD ewwwww

5. to do any drug calculations you always want to keep this formula in mind: dose desired divided by dose on hand gives you the dose to be given. to work this problem by dimensional analysis you will want to end up with an answer that has the label of "drops" in the numerator and "minutes" in the denominator. you set up an equation to do that. . .
dose desired: 1 mg/1 minute
dose on hand: 1 gram/500 cc

you also need to consider the drip factor of the tubing being used since the problem is asking you for the infusion rate to run this solution: 60 drops/1 ml.

conversion factor: 1 gram/1000 mg

you also must understand that a cc is equal to a ml.

1 mg/1 minute (dose desired) x 500 cc/1 gram (dose on hand) x 1 gram/1000 mg (conversion factor) x 60 gtts/1 ml (drip factor of iv tubing) = 30 gtts/minute
