A 3-year-old child with pyelonephritis weighing 33 lb
Question 1 of 5
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
Correct Answer: A
Rationale: The correct answer is A: 300 mg.
To calculate the dose, first convert the child's weight to kg (33 lb/2.2 = 15 kg).
Then, multiply the weight by the prescribed dosage (15 kg x 60 mg/kg/day = 900 mg/day). Since the dose is divided into three equal doses, each dose would be 900 mg/3 = 300 mg. This calculation ensures that the child receives the prescribed safe dose of ceftriaxone.
Choices B, C, and D are incorrect as they do not align with the calculated safe dosage based on the child's weight and the prescribed dosing regimen.
