Answer: 100mL/hr

Explanation:

Volume = 38mL

administered rate = 10mL/hr

Mass of dopamide = 209mg

Converting administered rate to mg/hr

(10mL/hr / 38mL) = (209mg / 1)

2090mL×mg /hr ÷ 38mL = 550mg/hr

Flow rate = (administered rate / mass) × volume

Flow rate = [ (550mg/ hr ÷ 209mg) × 38mL]

Flow rate = 2.6315789 hr × 38mL = 100mL/hr
