A nurse is preparing to administer amoxicillin 100 mg PO every 8 hr to a toddler who weighs 20 kg. The recommended dosage range is 20 to 25 mg/kg/day. Which of the following actions by the nurse is appropriate?
The nurse contacts the pharmacist to adjust the prescribed dosage.
The nurse determines the prescription is insufficient to achieve the desired effect.
The nurse determines the prescription is above the recommended dosage range.
The nurse administers the prescribed dosage.
The Correct Answer is B
To calculate the appropriate dosage of amoxicillin for the toddler; Given:
Weight of the toddler = 20 kg
Recommended dosage range = 20 to 25 mg/kg/day Calculate the total daily dose:
Minimum recommended dosage = 20 mg/kg/day Maximum recommended dosage = 25 mg/kg/day
Minimum total daily dose = 20 mg/kg/day × 20 kg = 400 mg/day Maximum total daily dose = 25 mg/kg/day × 20 kg = 500 mg/day
The prescribed dosage is 100 mg every 8 hours, which means 300 mg per day (100 mg × 3 times a day). As 300 mg is below the minimum recommended total daily dose (400 mg) for a toddler weighing 20 kg, the nurse should determine that the prescribed dosage is insufficient to achieve the desired effect.
