(Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1250"]
A child weighing 25 kilograms is receiving ampicillin 300 mg/kg/24 hours intravenously in equally divided doses every 4 hours.
This means that the child is receiving a total of 7500 mg of ampicillin per day (300 mg/kg/day × 25 kg = 7500 mg/day).
Since there are 24 hours in a day and the doses are given every 4 hours, the child will receive a total of 6 doses per day (24 hours/day ÷ 4 hours/dose = 6 doses/day).
Therefore, for each dose, the nurse should administer 1250 mg of ampicillin (7500 mg/day ÷ 6 doses/day = 1250 mg/dose).

Explanation
To calculate the infusion rate in mL/hour, we can use the following formula:
Infusion rate (mL/hour) = Volume (mL) / Time (hours)
In this case, the volume is 250 mL and the time is 2 hours. We can calculate the infusion rate as follows: 250 mL / 2 hours = 125 mL/hour
Correct Answer is ["239"]
Explanation
The child receives a prescription for asparaginase 4,780 IU IV.
The vial is labeled "Asparaginase 10,000 IU single-use vial" and for IV use, it should be reconstituted in 5 mL.
Since the child needs 4,780 IU of asparaginase and the vial contains 10,000 IU, the nurse should administer 2.39 mL of medication (4,780 IU / 10,000 IU * 5 mL).
