A child weighing 25 kilograms is receiving ampicillin 300 mg/kg/24 hours intravenously in equally divided doses every 4 hours. How many mg should the nurse administer to the child for each dose?
(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).

Correct Answer is ["8"]
Explanation
The client is receiving an IV infusion of regular insulin 60 units in 100 mL of normal saline at 5 units/hour. The concentration of insulin in the IV solution is 0.6 units/mL (60 units / 100 mL).
Since the healthcare provider prescribes 5 units/hour of insulin, the nurse should program the infusion pump to deliver 8 mL/hour of the IV solution (5 units/hour / 0.6 units/mL).
Correct Answer is ["83"]
Explanation
The client is receiving a liter of 0.9% normal saline solution to be administered over 12 hours.
Since 1 liter is equivalent to 1000 mL, the nurse should set the infusion pump to infuse 83 mL per hour (1000 mL / 12 hours).
