Question

Children’s chewable tylenol contains 80 mg of acetaminophen per tablet. if the recommended dosage is 10 mg/kg, how many tablets are needed for a 53−lb child?

Answer 1

Answer:

3 tablets are needed for a 53-lb child

Explanation:

1 lb = 0.4536 kg

So, 53 lb = $(53\times 0.4536)kg=24 kg$

So, weight of the child is 24 kg

For 1 kg body, recommended dosage is 10 mg

Hence, for 24 kg body, recommended dosage is $(10\times 24)mg$ or 240 mg

80 mg of acetaminophen is present in 1 tablet

So, 240 mg acetaminophen is present in $\frac{1}{80}\times 240$ tablets or 3 tablets.

So, 3 tablets are needed for a 53-lb child

Answer 2

53 pounds divided by 2.2 kilograms to get the converted weight which is 24.09 kilograms. Round this off to 24 kgs. 10 mg/kg multiply this to 24 kg, it would be 240 mg. 240 mg divided by 80 is 3. Therefore, a 53−lb child requires to have a dosage of 3 tablets.
