If a 12-kg child requires maintenance fluids at 44 mL/hr, how many milliliters are given over 6 hours?

Calculating maintenance fluids uses rate × time. For a 12-kg child, the 4-2-1 rule gives an hourly maintenance of 44 mL/hr (10 kg at 4 mL/kg/hr = 40 mL/hr, plus 2 kg at 2 mL/kg/hr = 4 mL/hr; total 44 mL/hr). Over 6 hours, the total is 44 × 6 = 264 mL. Therefore, 264 mL would be given in 6 hours. The other numbers correspond to multiplying 44 by different hours (e.g., 4, 8, or 12).
