Question

Quizplus · Accepted Answer

To find out the correct dose, we need to use the following formula:

Dose = Weight (kg) x Dose (mg/kg/day) / concentration (mg/mL) / frequency

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

33 lb = 33 ÷ 2.2 = 15 kg (rounded to nearest decimal)

Next, we can plug in the values into the formula:

Dose = 15 kg x 15 mg/kg/day / 250 mg/5 mL / 2

Dose = 1875 / 500

Dose = 3.75 mL per dose

Since the question asks for the dose to be divided into two doses per day, we need to divide the total daily dose by 2:

Dose per administration = 3.75 mL / 2

Dose per administration = 1.875 mL

Rounding to the nearest half mL, the correct answer is 2.5 mL (choice C).
