Step 2

The dosage is given in milligrams per kilogram, but the child's weight is in pounds. Our first step is to convert 110 pounds into kilograms.

Step 1: Weight Conversion

$$110 \text{ lb} \rightarrow ? \text{ kg}$$
3
Step 3

We use the standard conversion factor where 1 kilogram is equal to 2.2 pounds. So, we divide 110 by 2.2.

4
Step 4

110 divided by 2.2 gives us exactly 50 kilograms.

Step 5

Now that we have the weight in kilograms, we can calculate the dosage range. We will multiply the minimum and maximum recommended rates by the child's weight.

Step 2: Calculate Dosage Range

$$\text{Range} = [0.005, 0.01] \text{ mg/kg} \times W$$
