If a medication is ordered at 0.5 mL/kg/hr and the patient weighs 60 kg, what is the infusion rate in mL/hr?

• A. 30 mL/hr
• B. 15 mL/hr
• C. 20 mL/hr
• D. 25 mL/hr

Answer: (A)

Infusion rate in mL/hr is found by multiplying the ordered dose per kilogram per hour by the patient’s weight in kilograms. So 0.5 mL/kg/hr × 60 kg = 30 mL/hr. The infusion should run at 30 mL per hour.
