Answer:
- The dosage is 0.0906 g/kg
- The child should take 8.5 tablets to receive the same dosage
Explanation:
First we convert 134 lb into kg:
- 134 lb * = 60.702 kg
Then we<u> convert 275 mg into g</u>:
- 275 mg * = 0.275 g
Now we can<u> calculate the dosage in grams per kilogram of body weight,</u> keeping in mind that two tablets are consumed:
- (0.275 g) * 2 / 60.702 kg = 0.0906 g/kg
As for the<em> </em><em>second part</em>, first we <u>convert 31 lb into kg</u>:
- 31 lb * = 14.043 kg
Now we <u>calculate how many penicillin grams should be consumed</u>:
- 14.043 kg * 0.0906 g/kg = 1.27 g
We convert 1.27 g of penicilin into mg:
Finally we <u>calculate how many 150 mg tables should be taken</u>:
- 1270 mg / 150 mg = 8.5 tablets
