Maintenance fluids at 44 mL/hr for 8 hours would total how many milliliters?

• A. 264 mL
• B. 296 mL
• C. 352 mL
• D. 440 mL

Answer: (C)

Calculating maintenance fluids involves multiplying the hourly rate by the duration. 44 mL per hour for 8 hours is 44 × 8. Break it down: 40 × 8 = 320 and 4 × 8 = 32, so total is 352 mL. This directly reflects the rate times time. The other numbers would correspond to different durations (for example, 264 mL for 6 hours, 440 mL for 10 hours) or aren’t a clean multiple of 44 mL per hour.
