A male patient is receiving dextrose 5% at a rate of 55 mL/h. How much fluid will he receive in 11 hours?

• A. 605 mL
• B. 550 mL
• C. 660 mL
• D. 6050 mL

Answer: (A)

Total fluid delivered = infusion rate × time. With a rate of 55 mL per hour for 11 hours, multiply 55 by 11: 55 × 11 = 550 + 55 = 605 mL. So the patient will receive 605 mL. The other amounts would require different times or rates (for example, 550 mL would be 10 hours at 55 mL/h, 660 mL would be 12 hours at 55 mL/h, and 6050 mL would need 110 hours or a much higher rate).
