Answer 1

To calculate the daily dose of amoxicillin for a child weighing 20 pounds, convert the weight to kilograms and multiply by the dose per kg. The conversion gives approximately 9.09 kg, and multiplying by the 10 mg/kg dosage results in 90.9 mg/day, rounded to 91 mg/day.

Step-by-step explanation:

The question asks us to calculate the total daily dose of amoxicillin for a pediatric patient weighing 20 pounds, with the prescribed dosage being 10 mg/kg per day. To find the answer, we must first convert the weight from pounds to kilograms, knowing that 1 kilogram is equivalent to 2.2 pounds. Therefore, the weight in kilograms is 20 pounds divided by 2.2, which is approximately 9.09 kg. Next, we multiply the weight in kilograms by the prescribed dose per kilogram: 9.09 kg × 10 mg/kg equals 90.9 mg.

Since medication dosages are typically rounded to the nearest whole number, the total daily dose of amoxicillin for this patient would be rounded to 91 mg/day.
