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... Read More

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? - 0Aug 17, '13 by

Remember your conversions.

You have 5mg in 95ml. Now find how many mcgs.(5,000mcgs)

__Solution ml__

Drug mcg

**x 60 min/hr x kg x mcg/kg/min = ml/hr**

Thank you :-)

100ml x 60 x65kg x0.04= 15600 then divided by 5,000mcg equals 3.12 mls/hr is this correct or should I have converted the 0.04mcg into mg?
