Answer:
87 mg
Explanation:
To find the dose of acetaminophen for a 3-year-old child with the body surface area of 0.30 m², we use the formula given below
Child dose = child surface area/1.73 × adult dose
Given that the child surface area = 0.30 m² and the adult dose = 500 mg,
Child dose = child surface area/1.73 × adult dose
Substituting the values of the variables into the equation, we have
Child dose = child surface area/1.73 × adult dose
Child dose = 0.30 m²/1.73 × 500 mg
Child dose = 0.1734 × 500 mg
Child dose = 86.71 mg
Child dose = 87 mg to the nearest whole number
