Explanation / Answer

First we have to convert the weight of the child into kg. Since 1lb = 0.453 kb weight is 0.453 × 31 = 14.043kg.

Here it is stated that single dosage is 20mg per kg of body weight. Therefore we can calculate the total dosage that is needed for 14 kg ; (20mg/1kg) × 14.043 kg = 280.86 mg.

If a docter prescribed this amount for twice a day it should be double as 280.86 ×2 =561.72mg

The prescribed dosage is 2 times larger than the single one. And it is very higher than the adult dosage. Therefore giving two times a day is unsafe for a child
