8 mg = 8000mcg, so you have 8000 mcg in a 1000 mL bag which is the equivalent of 8 mcg per mL

Your patient is being infused at 60 mL per hour which is equal to 1mL per minute

The 1 mL has 8 mcg in it

so you would divide the 8 mcg by the patients weight in KG (90)

which equals 0.0888888 which rounds to 0.09 mcg/kG/min

I think that's right. I need to review formulas for my 2nd dosage calculations class this summer. Hopefully daytonite will come by and do it for you.

I got the same thing.

We never had to do this at my school (at least not yet) and so I'm just going by what was posted here and plugged all the current info into the formula Daytonite gave you....
first I figured if there is 8mg in 1000ml which is the same as 8mcg in 1ml
From there I just did everything Daytonite did and got
60ml (infused) x 8(dose on hand) / 90 (pt wt in Kg)/60 (minutes)=0.088 rounded to 0.09mcg/kg/minute.

Is this a different problem? 8 mg in 1000 mL infusing at 60 mL per hours (1 mL per minute) with a patient weight of 70 Kg. and you want to know what the mcg/kg/min are?
I do factor labeling to get all the labels needed into the equation and come up with:
8 mg/1000 mL (dose on hand) x 70 kg (patient weight)/hour (part of infusion rate) x 1000 mg/1 mg (conversion factor) x 1 hour/60 minutes (conversion factor) = 9.3333 mcg/kg/min, rounded to 9 mcg/kg/min

The answer my teacher gave was 19.05 mcg/kg/min.

I have no clue how she got it.

daytonite I think this patient is a different weight-90 kg. I don't see this in my calc with confidence book. Just how to take your mcg/kg/min and figure your per hour rate.

Oops! With the correction the answer comes out to 12 mcg/kg/min.
