Question

The average dosage of oxcarbazepine for an epileptic child between the ages of 4 and 16 is 9.00 mg per 1 kg of body weight (9.00 mg/kg). Calculate how many milliliters of oxcarbazepine a child who weighs 37.3 pounds should be prescribed considering the medication is served as a suspension of 60.0 mg/mL. Keep in mind that 1 pound is equivalent to 0.453 kilograms.

Answer 1

convert the child weight (37.3 pounds) to kilograms

37.3 lb x 0.453 kg /1lb = "A kg"

multiply the dose (9.00mg/kg) by the weight of the child to find how much you need to give him

A kg * 9.00 mg/1kg = "B mg" 

calculate the mL of suspension dividing the "B mg" by the concentration of the suspension 60.0 mg/mL

B mg * 1mL/ 60.0 mg = C mL oxcarbazepine

Answer 2

Answer:

2.53 milliliters of oxcarbazepine medication should be given to the child.

Explanation:

The average dosage of oxcarbazepine for an epileptic child = 9.00 mg/kg

Weight of the child = 37.3 pounds = 16.9 kg

(1 pound = 0.453 kilograms)

Dosage of oxcarbazepine for 16.9 kg child:

= $9.00 mg/kg\times 16.9 kg=152 mg$

Prescribed medication is served as 60.0 mg/mL which means that 60.0 mg of dose is present in 1 mL of water solution.

Then 152 mg of dose will be present in:

$\frac{1 mL}{60.0}\times 152=2.53 mL$

2.53 milliliters of oxcarbazepine medication should be given to the child.
