A toddler has an infection and fever. The nurse is preparing to administer acetaminophen elixir, ordered PRN every 4 hours. If the maximum daily dosage of acetaminophen is 60 mg/kg and the patient weighs 22 lbs, which of the following dosage options are acceptable?
Explanation
• The maximum daily dose for this patient is 600 mg, or 100 mg every 4 hours. While this is the maximum safe dose, effectiveness can be achieved with a lower dose while increasing patient's safety.
• Eighty milligrams (80 mg) every 4 hours is equivalent to 480 mg per day and is below the 100 mg/dose maximum.
22 lb = 10 kg
10 kg x 60 mg/kg = 600 mg per day maximum
600 mg/6 doses = 100 mg per dose maximum
