An infusion should deliver 750 mg over 3 hours. The solution concentration is 150 mg per 10 mL. What is the rate in mL/hr?

Explanation:
Infusion rate is found by turning the prescribed dose into the volume of solution using the concentration, then dividing that volume by the infusion time. The solution has 150 mg in 10 mL, which means 15 mg per mL. To deliver 750 mg, you need 750 ÷ 15 = 50 mL. Over 3 hours, the rate is 50 mL ÷ 3 h = 16.7 mL per hour. So the rate is 16.7 mL/hr.
