For a 30kg child receiving IV fluid maintenance, what is the correct hourly rate?

1. 60 mL/hr

2. 70 mL/hr

3. 80 mL/hr

4. 90 mL/hr

The correct answer is: 70 mL/hr

To determine the correct hourly rate for IV fluid maintenance in a child weighing 30 kg, the widely used "4-2-1 rule" is applied. This rule calculates the hourly rate based on the child's weight. According to the 4-2-1 rule: - For the first 10 kg of body weight, the child receives 4 mL/kg/hr. - For the next 10 kg (from 11 to 20 kg), the rate is 2 mL/kg/hr. - For any weight above 20 kg, the rate is 1 mL/kg/hr. Applying this to a 30 kg child: - The first 10 kg gets 4 mL/kg/hr, totaling 40 mL/hr (4 mL x 10 kg). - The next 10 kg gets 2 mL/kg/hr, totaling 20 mL/hr (2 mL x 10 kg). - The final 10 kg (from 21 to 30 kg) gets 1 mL/kg/hr, totaling 10 mL/hr (1 mL x 10 kg). Now adding these together: 40 mL/hr (first 10 kg) + 20 mL/hr (next
