Mind gone blank :/ help with calculations please :)

0 Hello everyone,
Okay so I seem to be having a blank moment, and can't seem to work out the answer to these calculations. I guess I just need a quick break down of how to work out the answer, and hopefully I will remember it all again.
1) For this question, I want to work out the mls per hour:
Epinephrine (Adrenaline)
5mgs (5mls) in 95mls of Dextrose 5% to run at 0.04mcg/Kg/min. (Patient weight= 65Kg)
2) If a patient is on lets say 10mls of Epinephrine (Adrenaline) an hour. How do I work out how many mcg/Kg/min is that (if there is 10mgs of Epinephrine in 90mls of Dextrose 5% and patient's weight is 95Kg)?
If anyone reading this is able to give me a mini tutorial on how to work the above answers, I would be forever grateful.
Thank you in advance, for taking the time to read this

Thank you for your response. I suppose I should have added what I have thought to be correct, the reason I did not do so, was due to the fact of thinking it was completely wrong, as well as never encountering such calculations before, and wanting to learn about them. It was never my intention to have you doing the homework. sorry if that is how my post came across.
Also I am unable to find the calculation to establish the mls/hr, which adds to my confusion of not knowing where to commence.

Aug 17, '13 by passionateaboutlifeThis is what I have, which i'm certain it is wrong and thus feel silly for even posting it
For my first question:
this is all i came up with:
0.04mcg x 65Kg x 60 =156 do I then divide the 156 (dose for this PT), by 5 mg and then multiply by 95 mls ?
This all sounds so wrong to me, even though at this stage I wouldn't even know if it is wrong or not.

Am i correct to think I will need 156 mcg in an hour? Do i then divide 156 by 1000, which will give me 0.156 mg? 
Aug 17, '13 by Esme12, ASN, BSN, RN Senior Moderatoryes.....now you need find out how many mcg/ml you have available in the bag. Remember your conversions.
You have 5mg in 95ml. Now find how many mcgs.(5,000mcgs) how many mcg/ml?
5000 = 52.6 mcg/ml
95
and you need 156mcg/hr. How many ml/hr needs to infuse to equal 156?
156mcg/hr = 2.9ml/hr rounded to 3ml/hr
52.6mcg/ml

Aug 17, '13 by OlivetheRN, ADN, BSN, RNQuote from passionateaboutlifeYep, you need 156 mcg/hr, so you're on thr right track. Next you need to figure out how many mcg you have per milliliter so that you can figure out your flow rate.Dear Loriangel14
