Answer :
Justin should receive a dosage of approximately 5902.053 mg.
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]
