The recommended childrens dosage of vibramycin is 2mg/LBS of body weight divided in 2 doses on first day. The child weighs 40 LBS. Vibramycin syrup is available in 50mg/5mL. Amount for 1 dose is:

Answer 1

The total dosage for the first day is 2 mg $\times$ 40 lbs = 80 mg is divided into two doses

Each dose is 2 $\div$ 80 = 40 mg for single divided dose

The required medication = required dose $\times$ available volume $\div$ available dose

                                        = 40 $\times$ 5 $\div$ 50

                                        = 4

The amount of medication for a single dose in two divided doses for the first day is 4 ml each dose.
