Answer: 1773.54 mg
Step-by-step explanation:
Given: The daily dose of ampicillin for the treatment of an ear infection is 115 mg/kg of body weight.
The weight of a child = 34 lb
We know that 1 pound = 0.453592 kg
Then , the weight of child in kilograms = [tex]0.453592\times34=15.422128\text{ kg}[/tex]
Now, the daily dose of ampicillin for the treatment of an ear infection for the child is given by :-
[tex]115\times15.422128=1773.54472\approx1773.54\text{ mg}[/tex]
Hence, the daily dose for a 34 lb child = 1773.54 mg
The conversion rate from Ib(pounds) to kg(kilograms)
1 Ib = 0.453592kg
Step 1
We convert the weight of the child to from lb to kg
1 Ib = 0.453592kg
34 lb = ?
Cross Multiply
34 x 0.453592kg
= 15.4221 kg
The weight of the child in kg = 15.4221 kg
Step 2
The daily dose of ampicillin for the treatment of an ear infection is 115 mg/kg of body weight.
Therefore the daily dose of ampicillin for the treatment of ear infection for the child = 15.4221 kg x 115 mg/kg
= 1,773.5415 mg
The daily dose for a 34 lb child is approximately to nearest whole number is 1,774 mg
