Answer :
Final answer:
To determine the amount of Infant Tylenol for a 16.9-pound child, convert pounds to kilograms, multiply by the dosage rate to find the total mg dose, and then convert the mg dose to the volume in mL using the medication's concentration. The child should be administered approximately 2.90 mL.
Explanation:
To calculate the amount of Infant Tylenol solution a 16.9 pound child should be given, based on a medication value of 12mg per kg of body weight, we need to follow a three-step process.
First, we convert the weight from pounds to kilograms, knowing that 1 kg equals 2.2 pounds:
16.9 lb ÷ 2.2 lb/kg = 7.68 kg (approximately).
Next, we calculate the total mg dose using the body weight:
7.68 kg × 12 mg/kg = 92.16 mg.
Finally, we convert the total mg dose to the volume of solution needed, using the concentration of the medication:
92.16 mg ÷ (159 mg/5 mL) = 2.90 mL (approximately).
Therefore, the child should be given approximately 2.90 mL of Infant Tylenol solution.
