Explanation:

Step1: Convert pounds to kilograms

We know that 1 lb = 0.453592 kg. For a 24 - lb child, the weight in kg is $24\times0.453592\approx10.9$ kg.

Step2: Calculate the recommended daily dosage

The usual dose for children is 15 mg/kg/day. For a 10.9 - kg child, the recommended daily dosage is $15\times10.9 = 163.5$ mg/day $\approx163.6$ mg/day.

Step3: Calculate the dosage per dose

The dose is divided into 2 equal doses. So the dosage per dose is $\frac{163.6}{2}=81.8$ mg/dose.

Step4: Check if the order is reasonable

The order is to give 78.5 mg twice a day. Since the recommended per - dose is 81.8 mg and 78.5 mg is close to 81.8 mg, the dosage of 78.5 mg is reasonable for this child.
