A nurse is reviewing a newly prescribed medication for a client. The order reads: Amoxicillin 500mg PO QD for 7 days. The order is initiated @ 0800 on 12/08/25. What is the termination date for this medication.
12/16/25
12/08/25
12/15/25
12/25/25
The Correct Answer is C
A. 12/16/25: Counting 7 days from 12/08/25 and including the start date results in a 7-day course ending on 12/15/25, not 12/16/25. Selecting 12/16/25 would extend the therapy by one extra day.
B. 12/08/25: The start date is 12/08/25; terminating on the same day would only allow a single dose, which does not complete the prescribed 7-day regimen.
C. 12/15/25: A 7-day course beginning on 12/08/25 concludes on 12/15/25. This includes the initial dose on 12/08/25 and provides the full duration of therapy as ordered.
D. 12/25/25: Ending on 12/25/25 would result in a 17-day course, exceeding the prescribed duration. This would lead to unnecessary antibiotic exposure and increase the risk of adverse effects or resistance.

Correct Answer is C
Explanation
Calculation:
- Identify the child’s weight and recommended dose range
Weight: 27 kg
Recommended dose: 25–50 mg/kg/day
- Calculate the safe dosage range
Minimum dose = 25 × 27
= 675 mg/day
Maximum dose = 50 × 27
= 1350 mg/day
Safe range = 675–1350 mg/day
- Compare the ordered dose to the safe range
Ordered Dose: 150 mg/day
150 mg is below the minimum recommended dose of 675 mg/day. The ordered dose is subtherapeutic and may not provide adequate treatment.
Correct Answer is C
Explanation
Calculation:
- Calculate the IV fluid intake
IV rate: 125 mL/hr
Time: 12 hours
IV intake = 125 × 12
IV intake = 1500 mL
- Identify the oral fluid intake
= 240 mL
- Calculate the total fluid intake
Total intake = IV intake + oral intake
Total intake = 1500 + 240
= 1740 mL
