A nurse is preparing to administer amoxicillin 100 mg PO every 8 hr to a toddler who weighs 20 kg. The recommended dosage range is 20 to 25 mg/kg/day. Which of the following actions by the nurse is appropriate?
The nurse determines that the prescription is insufficient to achieve the desired effect.
The nurse administers the prescribed dosage.
The nurse contacts the pharmacist to adjust the prescribed dosage.
The nurse determines that the prescription is unsafe as it is above the recommended dosage range.
The Correct Answer is A
A) The nurse determines that the prescription is insufficient to achieve the desired effect: Calculating the recommended dosage for a toddler weighing 20 kg, we get a range of 400 to 500 mg/day (20 to 25 mg/kg/day). The prescribed dosage of 100 mg every 8 hours (totaling 300 mg/day) falls below this range.
B) The nurse administers the prescribed dosage: Administering 100 mg every 8 hours (300 mg/day) would not provide the recommended daily dosage of 400 to 500 mg. Therefore, it would not be appropriate to administer the prescribed dosage without adjusting it.
C) The nurse contacts the pharmacist to adjust the prescribed dosage: Contacting the pharmacist is a reasonable step to ensure the prescribed dosage meets the recommended range. However, first recognizing that the current dosage is insufficient is the most immediate and critical action.
D) The nurse determines that the prescription is unsafe as it is above the recommended dosage range: The prescribed dosage of 300 mg/day is below the recommended range of 400 to 500 mg/day.

Correct Answer is ["195"]
Explanation
Given:
Client weight: 286 lbs
Prescribed dose: 1.5 mg/kg/dose
Steps to solve:
Convert weight to kg:
1 lb= 0.453592 kg.
Multiply: 286 lbs x 0.453592 kg/lb = 129.8 kg (rounded to one decimal place)
Calculate the dose:
Dose = 1.5 mg/kg/dose x 129.8 kg = 194.7 mg/dose
Round to the nearest whole number:
195 mg per dose.
Correct Answer is ["21"]
Explanation
To calculate the IV flow rate in drops per minute (gtt/min), we can use the following formula:
Flowrate(gtt/min) = (Totalvolumetobeinfused×Dropfactor) / Time
Given:
Total volume to be infused: 3000 mL
Drop factor: 10 gtt/mL
Time: 24 hours = 24 x 60 minutes = 1440 minutes
Flowrate(gtt/min):
(3000mL×10gtt/mL) / 1440minutes
Flowrate(gtt/min):
30000gtt / 1440minutes
Flowrate(gtt/min):
≈20.83gtt/min
Rounding to the nearest whole number:
21gtt/min
