A nurse is calculating the daily maintenance fluid needs for an adequately hydrated child who weighs 30 kg. If the child is to receive 25% of the fluids by the IV route, at what mL/hr flow rate should the nurse set the pump? Round to the nearest tenth milliliter.
A) 10.4 mL/hr
B) 17.7 mL/hr
C) 50.6 mL/hr
D) 70.8 mL/hr

The daily maintenance fluid needs for a child can be calculated using the following formula: 100 mL/kg for the first 10 kg, plus 50 mL/kg for the next 10 kg, plus 20 mL/kg for the remaining weight. For a 30 kg child, this would be (1000 mL for the first 10 kg) + (500 mL for the next 10 kg) + (400 mL for the remaining 10 kg) = 1900 mL/day. If the child is to receive 25% of these fluids by the IV route, that would be 25% of 1900 mL, which equals 475 mL/day. To find the flow rate in mL/hr, divide by 24 hours: 475 mL / 24 hr = 19.79 mL/hr, which rounds to 19.8 mL/hr. However, none of the provided options exactly match this calculation, suggesting a potential error in the calculation or in the interpretation of the options. Given the options, 17.7 mL/hr (B) is the closest and might be considered correct based on rounding or a slight variation in the calculation method, but it appears there might be a mistake in the calculation or option selection process.
