Answer:
Dosage of drugs is dependent on the body weight of a person. The route of administration also plays crucial role in determining the dosage of the drugs. The calculation of dosage of drugs based on the bodyweight is calculated by the multiplication of body weight and dosage.
Explanation:
The medication dosage is given as 45mg/kg. To calculate the mass of dosage a child will require of body weight 33.5lb will be:
[tex]\text{Dose} = \text{Body weight} \times \text{Dosage}[/tex]
Therefore, converting the pounds to kg, it will be:
[tex]33.5\;\text{lb} = 15.19\;\text{ kg} \;(1\;\text{lb} = 0.4\;\text{ kg})[/tex]
Thus, dose of medication required will be:
[tex]\text{Dose} = 15.19 \: \times \: 45[/tex]
[tex]\text { Dose} = 683.8\: \text { mg}[/tex]
