Question

An infant acetaminophen suspension contains 80 mg/0.80 mL suspension. The recommended dose is 15 mg/kg body weight.

How many milliliters of this suspension should be given to an infant weighing 13 lb.

Answer 1

0.8853 mL

Step-by-step explanation:

First we convert 13 lb to kg, keeping in mind that 1 lb = 0.454 kg:

• 13 lb *
  `(0.454kg)/(1lb)` = 5.902 kg

Then we calculate how many mg of acetaminophen should be given, using the recommended dose and infant mass:

• 15 mg/kg * 5.902 kg = 88.53 mg

Finally we calculate the required mL of suspension, using its concentration:

• 88.53 mg ÷ (80 mg/0.80 mL) = 0.8853 mL
