A 3-year-old child is hospitalized with a diagnosis of pyelonephritis The health care provider has prescribed ceftriaxone 60 mg/kg/day in three divided doses. The child weighs 33 lb. The dose ordered is the safe dose, How many milligrams should the nurse administer in each dose? Record your answer using a whole number
The Correct Answer is ["300"]
To calculate the dose of ceftriaxone for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs 33 pounds, which is approximately 15 kilograms when divided by 2.2. The prescribed dose is 60 mg/kg/day, so for a 15 kg child, this would be 900 mg per day. Since the medication is to be administered in three divided doses, you would divide 900 mg by 3, resulting in 300 mg per dose.
