The healthcare provider prescribes an IV solution of ampicillin 1 gram in 50 mL of Dextrose in Water (D/W) at 25 drops/minute. The nurse uses an infusion set that delivers 15 drops/mL and starts the infusion at 1900. Using the 24- hour clock, what time should the nurse anticipate the infusion to be completed?
(Enter numeric value only.)
The Correct Answer is ["1930"]
The healthcare provider prescribes an IV solution of ampicillin 1 gram in 50 mL of Dextrose in Water (D/W) at 25 drops/minute.
The nurse uses an infusion set that delivers 15 drops/mL.
This means that the infusion rate is 1.67 mL/minute (25 drops/minute ÷ 15 drops/mL = 1.67 mL/minute).
Since the total volume of the solution is 50 mL, it will take approximately 30 minutes to infuse the entire solution (50 mL
÷ 1.67 mL/minute = 30 minutes).
If the nurse starts the infusion at 1900 (7:00 PM), the infusion should be completed at approximately 1930 (7:30 PM).

Correct Answer is ["1250"]
Explanation
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 ["22"]
Explanation
The client receives a prescription for heparin sodium 20,000 Units in 5% dextrose injection 500 mL to be infused at a rate of 880 units/hour.
The concentration of heparin in the IV solution is 40 units/mL (20,000 units / 500 mL).
Since the healthcare provider prescribes 880 units/hour of heparin, the nurse should program the infusion pump to deliver 22 mL/hour of the IV solution (880 units/hour / 40 units/mL).
