"40 mcg/min" is correct. To calculate this result, the nurse should first calculate the amount of mg/hour.
To do this, the nurse takes the rate and divides it by the volume in the bag:
30 mL/hr divided by 500 mL = 0.06 hr/ml
This is then multiplied by the dose available:
0.06 x 40 mg (in the bag) = 2.4 mg/hr
The dose is then converted from mg/hr to mcg/min:
2.4 mg/hr divided by 60 minutes = 0.04 x 1000 = 40 mcg/min
