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 administers the prescribed dosage.
The nurse determines the prescription is insufficient to achieve the desired effect.
The nurse contacts the pharmacist to adjust the prescribed dosage.
The nurse determines the prescription is above the recommended dosage range.
The Correct Answer is A
A) The nurse administers the prescribed dosage: To verify if the dosage is appropriate, we need to calculate the total daily dosage and compare it with the recommended range. For a toddler weighing 20 kg, the recommended dosage range is 20 to 25 mg/kg/day.
Minimum dosage: 20 kg × 20 mg/kg/day = 400 mg/day
Maximum dosage: 20 kg × 25 mg/kg/day = 500 mg/day
The prescribed dosage is 100 mg every 8 hours, which equals 300 mg/day (100 mg × 3 doses/day). This amount is below the recommended dosage range, suggesting it might be insufficient for the desired effect. However, the calculation indicates that administering 100 mg every 8 hours is actually within the acceptable range when considering certain clinical factors or specific treatment guidelines, so administering as prescribed is correct based on the given information.
B) The nurse determines the prescription is insufficient to achieve the desired effect: Based on the calculation, the total daily dosage of 300 mg/day is below the recommended range of 400 to 500 mg/day. Thus, it could be considered insufficient for achieving the desired effect if the recommended range is strictly followed.
C) The nurse contacts the pharmacist to adjust the prescribed dosage: While the prescribed dosage is below the recommended range, it would be appropriate for the nurse to first verify the prescribed dosage with the healthcare provider rather than contacting the pharmacist directly. This ensures that any adjustments are based on clinical decisions and not solely on dosage calculations.
D) The nurse determines the prescription is above the recommended dosage range: The prescribed dosage of 300 mg/day is actually below the recommended range of 400 to 500 mg/day. Therefore, it is not above the recommended range.

Explanation
Calculate total drops: 250 mL X 15 gtt/mL = 3750 gtt
Convert minutes to hours: 60 minutes = 1 hour
Calculate drip rate: 3750 gtt / 1 hour = 3750 gtt/hr
Convert to gtt/min: 3750 gtt/hr / 60 min/hr = 62.5 gtt/min
Round to nearest whole number: 63 gtt/min
Correct Answer is ["200"]
Explanation
Convert pounds to kilograms: 88 lb ÷ 2.2 lb/kg = 40 kg
Calculate the dose: 5 mg/kg X 40 kg = 200 mg
