0Jan 28, '13 by EmilyEmily1. An infusion ordered of 2g in 500 mL is ordered at 60mL/hr

2Jan 28, '13 by KelRN215, BSN, RNQuote from EmilyEmilyWhat is the question asking? What you posted here isn't a question, it's an order telling you that you are to infuse a medication which contains 2g in 500 mL of fluid at 60 mL/hr.1. An infusion ordered of 2g in 500 mL is ordered at 60mL/hr
2g/500mL ???

0Jan 28, '13 by EmilyEmilyAn infusion of 2g in 500mL is ordered at 60mL/hr
what is the mg/min dosage?
and what is the mg/hr dosage?
2g/500mL but how do I convert g to ml? 
0Jan 28, '13 by KelRN215, BSN, RNQuote from EmilyEmilyYou don't "convert" g to mL, you convert g to mg and then you figure out the concentration.An infusion of 2g in 500mL is ordered at 60mL/hr
what is the mg/min dosage?
and what is the mg/hr dosage?
2g/500mL but how do I convert g to ml?
You have 2 g in 500 mL. So how many mg does that mean you have in 500 ml? How many mg in 1 mL? That's your concentration. So you then know your concentration is X mg/mL and the rest is just plugging in numbers. 
6Jan 28, '13 by GrnTea, BSN, MSN, RNEmilyemily, Emilyemily, dear, we have shown you how to do that several times already. Think, dear. There is no magic in this. If you have 300 total cookies in six boxes, how many cookies are there in each box? If you eat half a box a day, how many cookies will you eat on Tuesday? If you eat half a box a day, how many cookies will you eat on Weds, Thurs, and Fri?
See? It's not that hard.
First: If you have 2 grams in 500 ml, how do you figure out how many mg there are in 500 ml?
Then: How do you figure out how many mg in 1 ml?
Then: How many mg are there in 60 ml?
Show your work and I hope nobody gives it to you here because you need, desperately, to figure out how to think about these kinds of problems.Last edit by GrnTea on Jan 28, '13 
0Jan 28, '13 by GrnTea, BSN, MSN, RNQuote from EmilyEmilyYou have the right answer but I can't see how you got there. In your first line, your answer would be 4mg/cc. Keeping the right units is important.2000mg/500mL =4
2000mg/500mL x 60mg/1hr= 240mg/hr
is that right?
Then your next step would be 4mg/cc x 60cc/hr, and that would come out to be the 240 mg/hr.
If you want us to help you, show us your work first so we can either 1) say Brava! or 2) show you where you need to think about it some more. 
0Jan 28, '13 by KelRN215, BSN, RNQuote from EmilyEmilyExactly. Your concentration is 4 mg/mL. You're infusing the medication at 60 mL/hr so if you multiply that by 4 mg/mL, you know you are infusing 240 mg in an hour.2000mg/500mL =4
2000mg/500mL x 60mg/1hr= 240mg/hr
is that right?
Now what's your mg/min dosage? Your question also asked that... 
0Jan 28, '13 by EmilyEmilyI'm having trouble finding the flow rate with this problem
A 3mg/min dosage is ordered. The solution strength is 2g in 500 mL. What is the mL/hr flow rate?
2g/500mL...
I dont know what the mL/hr flow rate formula is..my book does not show me how to do this type of problem
