A child who weighs 66 pounds receives a prescription for amoxicillin 80 mg/kg/day by mouth in divided doses every 12 hours. How many mg should the nurse administer with each dose?
(Enter numerical value only.)
The Correct Answer is ["1200"]
A child who weighs 66 pounds receives a prescription for amoxicillin 80 mg/kg/day by mouth in divided doses every 12 hours.
Since 1 kg is equal to 2.2 pounds, the child weighs approximately 30 kg (66 pounds ÷ 2.2 pounds/kg = 30 kg).
This means that the child is receiving a total of 2400 mg of amoxicillin per day (80 mg/kg/day × 30 kg = 2400 mg/day).
Since there are 24 hours in a day and the doses are given every 12 hours, the child will receive a total of 2 doses per day (24 hours/day ÷ 12 hours/dose = 2 doses/day).
Therefore, for each dose, the nurse should administer 1200 mg of amoxicillin (2400 mg/day ÷ 2 doses/day = 1200 mg/dose).

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).
Correct Answer is ["1930"]
Explanation
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).
