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:
To calculate the dose of ceftriaxone for the child:
1. Convert the child's weight from pounds to kilograms: 33 lb ÷ 2.2 = 15 kg
2. Calculate the total daily dose: 60 mg/kg/day x 15 kg = 900 mg/day
3. Divide the total daily dose into 3 equal doses: 900 mg ÷ 3 = 300 mg/dose
Therefore, the correct answer is A: 300 mg. This is the safe dose based on the child's weight and the prescribed dosage regimen.
Incorrect choices:
B: 350 mg - Incorrect, exceeds the calculated safe dose.
C: 400 mg - Incorrect, exceeds the calculated safe dose.
D: 450 mg - Incorrect, exceeds the calculated safe dose.
