The average dosage of oxcarbazepine for an epileptic child between the ages of 4 and 16 is 9.00  mgmg  per 1  kgkg  of body weight (9.00  mg/kgmg/kg). calculate how many milliliters of oxcarbazepine a child who weighs 42.9 pounds should be prescribed considering the medication is served as a suspension of 60.0  mg/mlmg/ml. keep in mind that 1 pound is equivalent to 0.453 kilograms.

The answer to your question is 3 ml

Explanation:

Data

Dosage = 9.0 mg/ kg

Child's weight = 42.9 pounds

Suspension = 60 mg/ml

milliliters = ?

Process

1.- Convert the weight to kg

                         1 pound 0.453 kg

                     42.9 pounds  x

                           x = (42.9 x 0.453) / 1

                           x = 19.43 kg

2.- Calculate the milligrams the child needs

                         1 kg of weight 9 mg

                       19.43 kg  x

                            x = (19.43 x 9) / 1

                            x = 174.87 mg of oxcarbazepine

3.- Calculate the milliliters needed

                          60 mg of suspension 1 milliliters

                        174.87 mg                      x

                                 x = (174.87 x 1) / 60

                                 x = 2.9 ml ≈ 3 ml
