Expert Solution

Ordered amount of drug=4mcg

Weight of the patient=198lbs,ie 198/2.2=90kg

Available dose=250mg

Available volume=250ml

First find out drug concentration,

Drug Concentration= 250mg/250ml =1mg/ml

To convert mg to mcg =1mg×1000=1000mcg per ML

(Ordered amount of drud×pt's weight×60min/hr)/drug concentration

=(4mcg×90kg×60)/1000mcg=21.6ml/hr
