Question

calculate the 24 - hour maintenance fluid for a child who weighs 7 kg.
the provider wants this child to receive half of the daily maintenance fluid volume by iv.
calculate the ml/hr flow rate.
ml/hr (round answer to the whole number)

Explanation:

Step1: Calculate 24 - hour maintenance fluid

For a child weighing less than 10 kg, the 24 - hour maintenance fluid is calculated as \(100\space mL/kg\).
If the child weighs \(7\space kg\), then the 24 - hour maintenance fluid \(V = 100\times7=700\space mL\)

Step2: Calculate the volume to be given by IV

The provider wants half of the daily maintenance fluid volume by IV. So \(V_{IV}=\frac{700}{2} = 350\space mL\)

Step3: Calculate the mL/hr flow rate

We know that the time \(t = 24\space hr\). The flow rate \(r=\frac{V_{IV}}{t}\)
Substitute \(V_{IV} = 350\space mL\) and \(t = 24\space hr\) into the formula: \(r=\frac{350}{24}\approx14.58\space mL/hr\)

Answer:

\(15\space mL/hr\)
