first off 40/2.2= 18.18 or 18.2(kg)
now lets pick the lowest dose ordered which is 10 mg
so- 10 x 18.2 = 182 mg- max dose per day, since the drug has to be given twice a day divide 182/2 = 91 mg each dose.
now pick the highest dose ordered which is 25 mg
so 25 x 18.2= 455 mg max dose per day, since the drug has to be given twice a day divide 455/ 2= 227.5 mg each dose.
so basically the max dose for the day is anywhere btwn 182 mg - 455 mg. each dose or one dose ranges anywhere from 91 mg to 227.5 mg per dose. good luck!
to compute this you need to convert 10-15/mg/kg/day into what it would be for a 40 pound child. in effect you have two problems to solve:
you know i like to use dimensional analysis to solve these.
what is the lowest recommended daily dose for a 40 lb child if the recommended dose is 10-25 mg/kg/day?
i want to end up with mg/day in the final answer. 1 kg = 2.2 lb
what is the highest recommended daily dose for a 40 lb child if the recommended dose is 10-25 mg/kg/day?
again, i want to end up with mg/day in the final answer. 1 kg = 2.2 lb
the question asks you to determine the maximum recommended dose for a 40mg child. the safe range with the newly computed figures would be 182-455 mg/40 lb/day. therefore, the maximum safe dose would be the 455 mg/day for a 40 pound child.
your final answer was correct, but i has having trouble following your set up. it's probably because of the limitations of what we can do with the text on this software.

The recommeneded dose of Mysolin is 10-25 mg/kg/day divided bid. Determine the maximum recommended dose for a 40 pd child in mg.
mg/day
10-25 mg/kg/day
40 pd
2.2 pd/kg
mg/day = 10 (25)mg /kg/day x kg /2.2 pd x 40 pd/1 = 182 (455) mg/day min(max) so the maximum would be 455 ? Am I approaching this problem correctly ?
