Using the same parameters as above (8 mcg/kg/min, 86 kg, 1600 mcg/mL), what is the infusion rate in mL/hour?

Using the same parameters as above (8 mcg/kg/min, 86 kg, 1600 mcg/mL), what is the infusion rate in mL/hour?

• A. 12.9
• B. 40.0
• C. 51.6
• D. 25.8

Answer: (D)

To find the infusion rate, convert the prescribed dose to a rate in mcg per minute and then to mL per hour using the solution’s concentration. First, dose rate in mcg/min = 8 mcg/kg/min × 86 kg = 688 mcg/min. Convert to mcg/hour: 688 × 60 = 41,280 mcg/hour. With a concentration of 1600 mcg/mL, the infusion rate is 41,280 mcg/hour ÷ 1600 mcg/mL = 25.8 mL/hour. The infusion rate is 25.8 mL/hour.
