A child is prescribed amoxicillin (42mg/kg/day) to be given 3 times per day. If he weighs 35 pounds, what is the maximum dose that he should receive? (round to the nearest whole number)

Answer :

Answer:

The child should receive a maximum of 661.5mg of amoxicillin, divided into 3 times per day of a 221mg dose.

Explanation:

1st) It is necessary to use the relation between kg and pounds (1 pound = 0.45kg).

[tex]35pounds*\frac{0.45kg}{1pound}*42\frac{mg}{kg*day}=661.5\frac{mg}{day}[/tex]

2nd) Now that we know the the child needs 661.5mg/day, it is necessary to divide that amount by 3, to calculate the dose:

[tex]\frac{661.5mg}{3}=220.5mg[/tex]

So, the child should receive a maximum of 661.5mg of amoxicillin, divided into 3 times per day of a 221mg dose.
