Weight - 20 pounds 6 ounces

Ordered dose - 1.5mg per kilogram per day
recommended dosage from drug label - 3mg every 8 hours.

1.What is the individual dose?

to find the individual dose i'll first convert pounds to kg which is 9.26 kg. I will then multiply 1.5 x 9.26 = 13.89 mg. So the individual dose is 13.89 mg.

2.What is the daily dose?

to find the daily dose I would multiply 13.89 x 3 = 41.67 mg.

However,the back of the answer states that individual dose is 4.63mg and daily dose is 13.89 mg.

Why is that?
