A Physician orders Zithromax suspension 10mg/kg per day to be divided equally twice a day for a child who weighs 88 lb with acute bronchitis.

How many mg will the child receive per dose?

1kg = 2.205lbs

10mg per 2.205

10/2.205

10 mg/2.205lbs = x/88lbs

Now we solve for z

10 times 88 = 880 divided by 2.205 =

(Nearest tenths) = 399.1

Thats for the day, there are 2 doses in one day, divide it by 2.

Which equals to 199.55

Answer: 199.55mg
