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 ["2"]
Explanation
The bottle is labeled "Ibuprofen for Oral Suspension, USP 100 mg per 5 mL." This means that for every 5 mL (or 1 teaspoon) of the suspension, there is 100 mg of ibuprofen.
To administer a dose of 200 mg, the parent should give the child 2 teaspoons (10 mL) of the suspension.
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).
