Question

child weighs 5100 g.
how many milliliters per hour are needed to deliver the maintenance fluid.

number
check

Explanation:

Step1: Convert grams to kilograms

Since \(1\ kg = 1000\ g\), then \(5100\ g=\frac{5100}{1000}=5.1\ kg\)

Step2: Calculate maintenance fluid

For children, the formula for maintenance fluid is:

• First \(10\ kg\): \(100\ mL/kg/day\)
• Second \(10\ kg\): \(50\ mL/kg/day\)
• Remaining \(kg\): \(20\ mL/kg/day\)

For a \(5.1\ kg\) child, using the formula \(100\ mL/kg/day\) (since \(5.1\ kg<10\ kg\))

The total fluid per day \(=100\times5.1 = 510\ mL/day\)

Step3: Calculate fluid per hour

Since there are \(24\) hours in a day, then fluid per hour \(=\frac{510}{24}=21.25\approx21\ mL/hour\)

Answer:

\(21\)
