Question

calculate the 24 - hour maintenance fluid for a child who weighs 6700 g. round answer to whole number.
ml
check

Explanation:

Step1: Convert grams to kilograms

Since \(1\space kg = 1000\space g\), then \(6700\space g=\frac{6700}{1000}=6.7\space kg\)

Step2: Use the Holliday - Segar formula for fluid maintenance

For children, the formula for 24 - hour fluid maintenance is:
For the first \(10\space kg\) of body weight: \(100\space ml/kg\); for the second \(10\space kg\): \(50\space ml/kg\); for weight over \(20\space kg\): \(20\space ml/kg\)
Since \(6.7\space kg<10\space kg\), the fluid maintenance \(=100\times6.7 = 670\space ml\)

Answer:

\(670\)
