Justin is taking an anti-inflammatory drug, and the instructions state that the patient must receive 99 mg for each 2 kg of body weight. If Justin weighs 263 lb, what dosage should he receive?

To find out the appropriate dosage for Justin, we need to follow a few steps and make some conversions from pounds to kilograms, and then apply the dosage per kilogram.

Convert weight from pounds to kilograms

Since 1 kilogram is approximately 2.20462 pounds, we convert Justin’s weight from pounds to kilograms:

[tex]\text{Weight in kg} = \frac{263 \text{ lb}}{2.20462 \text{ lb/kg}} \approx 119.294 \text{ kg}[/tex]

Calculate the dosage

The instructions say 99 mg of the drug per 2 kg of body weight.

We need to find out how much he should receive based on his weight in kilograms:

First, calculate the dosage per kilogram by dividing 99 mg by 2:

[tex]\text{Dosage per kg} = \frac{99 \text{ mg}}{2 \text{ kg}} = 49.5 \text{ mg/kg}[/tex]

Then, multiply the dosage per kilogram by Justin’s weight in kilograms:

[tex]\text{Total dosage in mg} = 49.5 \text{ mg/kg} \times 119.294 \text{ kg} \approx 5902.053 \text{ mg}[/tex]
