A female patient is receiving Hartmann's solution at 125 mL/h for 5 hours. How much solution will she receive?

• A. 625 mL
• B. 500 mL
• C. 750 mL
• D. 600 mL

Answer: (A)

The key idea is that total fluid delivered equals the infusion rate multiplied by the time. At 125 mL per hour for 5 hours, the total volume is 125 × 5 = 625 mL. Quick check: 125 mL/h for 4 hours is 500 mL; one more hour adds another 125 mL, reaching 625 mL. The type of solution doesn’t change the calculation—just the rate and duration determine the total.
