A child who weighs 40 kg receives a prescription for acetaminophen 15 mg/kg/dose PO every 4 to 6 hours PRN for fever. What is the maximum daily dose the nurse should administer? (Enter the numerical value only.)
Explanation & Rationale
Here's how to calculate the maximum daily dose of acetaminophen for the child: Calculate the maximum dose per administration: Maximum dose per kg per administration = 15 mg/kg (given) Child's weight = 40 kg (given) Since this is a PRN medication (given as needed), we will calculate the maximum dose per administration based on the prescribed dosage. Maximum dose per administration = 15 mg/kg/dose * 40 kg Maximum dose per administration = 600 mg (round to nearest whole number) Calculate the number of administrations in a 24-hour period (maximum): Frequency: Every 4 to 6 hours PRN (given) Since this is a PRN medication, we will assume the maximum frequency (every 4 hours) for calculating the maximum daily dose. Number of administrations (maximum) = 24 hours / Frequency (hours/administration) Number of administrations (maximum) = 24 hours / 4 hours/administration Number of administrations (maximum) = 6 administrations Calculate the maximum daily dose: Maximum daily dose = Maximum dose per administration x Number of administrations (maximum) Maximum daily dose = 600 mg/administration * 6 administrations Maximum daily dose = 3600 mg Therefore, the maximum daily dose the nurse should administer is 3600 mg.
