A patient receives 2 liters of IV fluids over 24 hours. What is the infusion rate in mL/hr?

• A. 60 mL/hr
• B. 83 mL/hr
• C. Approximately 83 mL/hr
• D. 120 mL/hr

Answer: (C)

Infusion rate = total volume ÷ time. Convert 2 liters to milliliters: 2 L = 2000 mL. Then 2000 mL ÷ 24 hours = 83.33 mL/hour. In practice, we round, so the rate is about 83 mL/hour. The option that says approximately 83 mL/hr matches this calculated value.
