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 ["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).
Correct Answer is ["40"]
Explanation
A client with heart failure (HF) is receiving an IV infusion of 0.9% normal saline 250 mL at a keep-vein-open (KVO) rate of 40 mL/hour.
The IV tubing has a minidrip chamber that delivers 60 microdrops/mL.
To calculate the infusion rate in microdrops/minute, we need to multiply the infusion rate in mL/hour (40 mL/hour) by the number of microdrops/mL (60 microdrops/mL) and divide by the number of minutes in an hour (60 minutes/hour).
The nurse should regulate the microdrop gravity IV infusion to deliver 40 microdrops/minute (40 mL/hour * 60 microdrops/mL / 60 minutes/hour).
