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 ["3"]
Explanation
Given:
Prescribed dose: 900 mg of gabapentin per dose
Available tablets: 300 mg capsules
Steps to solve:
Determine the number of capsules per dose:
Find how many 300 mg capsules are needed to make 900 mg of gabapentin.
Set up a proportion to solve for the unknown number of capsules (X):
300 mg/capsule = 900 mg/X capsules
Cross-multiplying gives us:
300 mg x X capsules = 900 mg x 1 capsule
Simplifying:
300X = 900
Solving for X:
X = 900 / 300 = 3 capsules
Correct Answer is ["100"]
Explanation
Given:
Total volume: 200 mL
Time: 2 hours
Steps to solve:
Determine the flow rate:
Set up a proportion to solve for the unknown flow rate (X):
200 mL/2 hr = X mL/1 hr
Cross-multiplying gives us:
200 mL x 1 hr = 2 hr x X mL
Simplifying:
200 = 2X
Solving for X:
X = 200 / 2 = 100 mL/hr
