*loriangel14***Guide**After the loading dose?

Why don't you tell us what you have come up with so far? You won't learn anything from us doing your homework for you.This fairly straightforward. How do you think you would do this question? - 1Apr 16, '13 by
*loriangel14***Guide**Their answer makes no sense.

92.7 x 6 = 556.2. Two doses a day would be 1112.4mg daily.

92.7 x 4=370.8. Two doses a day would be 741.6 mg daily.

You don't divide the dose, you would multiply it.Each dose was given twice a day.

Maybe someone else will come up with an answer.Esme12 likes this. - 0Apr 16, '13 by HeatherMaxWell, I am out I couldn't make my answer match the book. (but why did you divide rather than multiply by the two doses per 24 hours given)

*Esme12***Asst. Admin**As did I.....

The patients loading does is......

92.7(kg) x 6(mg/kg) = 556.2(mg/kg/dose) times 2 doses(q 12 hours).....

which is 556.2(mg/kg/dose) x 2(doses) = 1112.4

The daily dose is ........

92.7(kg) x 4(mg/kg) = 370.8(mg/kg/dose) time 2 doses(q 12 hours)......

which is 370.8(mg/kg/dose) x 2(doses) = 741.6
