Quizplus · Accepted Answer

First, convert the weight of the child from pounds to kilograms:

30.0 pounds ÷ 2.205 lb/kg = 13.6 kg

Then, calculate the total dose of amoxicillin the child should receive:

40.0 mg/kg/day x 13.6 kg = 544 mg/day

Next, divide the total dose by the concentration of the suspension to find the amount of mL needed per dose:

544 mg/day ÷ 400 mg/5 mL = 6.8 mL/dose

Round to the nearest hundredth:

6.8 mL/dose ≈ 6.82 mL/dose

Therefore, the correct answer is B. 6.82 mL.
