Question

Quizplus · Accepted Answer

Step 1: Convert the child's weight from pounds to kilograms
55 pounds ÷ 2.2 = 25 kg

Step 2: Calculate the total daily dose
30 mg/kg/day x 25 kg = 750 mg/day

Step 3: Determine the dose per administration
Assuming the medication comes in a concentration of 100 mg/5 mL, we can calculate the dose per administration by dividing the total daily dose by the number of doses per day:
750 mg/day ÷ 3 doses/day = 250 mg/dose

Then, we can convert this to mL using the concentration:
250 mg ÷ 100 mg/5 mL = 12.5 mL

Rounding to the nearest mL, the child should receive 5 mL of this medicine per dose (option D).
