Calculation problem

Can someone please help me with this calculation? I'm not just looking for an answer, but how do you go about getting the answer. Thanks so much

Order: add 2 grams Thiamine to 1000 cc IV fluids

Available: 500 per 5cc

Volume in IV fluid bag 500 cc.

The order is to put the 2 grams into 1000 cc of IV fluid but your IV fluid bags contain 500cc. So you're going to have to divide the 2 grams of Thiamine between the two 500 cc bags.

I gather that the available should read 500mg per 5cc.

So ask yourself how many mg are in a gram? Then how many units of '500 mg per 5cc' do you need to make 2 grams?

Hope this makes sense.

Order: add 2 grams Thiamine to 1000 cc IV fluids

Available: 500 per 5cc

Volume in IV fluid bag 500 cc.

DO (dose ordered)

DH (dose on hand) =___________ x ___ml (the drug NOT the bag) =________

so

2000 mg (Dose Ordered)

500 mg (Dose on Hand )= ____4_______ x 5 ml (given in the question 500 per 5cc) = 20 ml

so 20 ml would be for a 1000 ml bag but all you have are 500 ml bags. I know it's easy to see but incase you find one that is not.

1000 ml

500 ml = ___2___ so you know to divide 20 by __2___

20ml

2 = 10 ml

Answer:

10ml in a 500 ml bag

I hope this helps and I didn't confuse you more.
