A nurse is reviewing new prescriptions for a client who was just admitted. For which of the following prescriptions should the nurse obtain further clarification from the provider?
Aspirin 81 mg PO daily
Acetaminophen 1000 mg PO every 6 hours prn for mild-moderate pain
Ibuprofen 400 mg PO every 4 hours prn for mild-moderate pain
Amoxilin 250 mg tablet PO X7 days
The Correct Answer is D
A. Aspirin 81 mg PO daily:
Aspirin 81 mg daily is commonly used as a low-dose regimen for cardiovascular protection or as a preventive measure for certain conditions. This dosage is standard and does not require clarification.
B. Acetaminophen 1000 mg PO every 6 hours prn for mild-moderate pain:
The maximum recommended dose of acetaminophen is generally 4000 mg per day. A dose of 1000 mg every 6 hours, which totals up to 4000 mg daily, is within the acceptable limit for managing mild to moderate pain, assuming no liver dysfunction is present. This prescription is appropriate and does not need further clarification.
C. Ibuprofen 400 mg PO every 4 hours prn for mild-moderate pain:
Ibuprofen is typically dosed at 200 mg to 400 mg every 4 to 6 hours as needed. A dose of 400 mg every 4 hours is within the usual range for managing mild to moderate pain, and the total daily dosage should be monitored to avoid exceeding recommended limits. This prescription is generally acceptable.
D. Amoxicillin 250 mg tablet PO X7 days:
Amoxicillin is usually prescribed at higher doses for infections. A common dosage is 500 mg to 875 mg every 8 hours, depending on the infection being treated. The prescription of 250 mg for 7 days is unusually low and might not be effective for most infections, requiring clarification to ensure appropriate antibiotic therapy.

Correct Answer is ["1880"]
Explanation
Understanding the problem
We need to calculate the total fluid intake in mL.
We have various fluids in ounces and mL.
There is a continuous IV infusion at 50 mL/hr for 12 hours.
Step-by-step calculation
Convert ounces to milliliters:
1 oz = 30 mL
Orange juice (½ cup):
½ cup = 4 oz → 4 oz = 120 mL
Milk:
8 oz = 240 mL
Coffee:
6 oz x 30 mL/oz = 180 mL
Ice chips:
4 oz x 1/2 x 30 mL/oz = 60 mL
Gelatin:
6 oz x 30 mL/oz = 180 mL
Decaffeinated coffee:
6 oz x 30 mL/oz = 180 mL
Apple juice:
4 oz x 30 mL/oz = 120 mL
Water: 200 mL
Calculate total oral fluid intake:
Calculate IV fluid intake:
IV fluid intake = 50 mL/hr x 12 hours = 600 mL
Calculate total fluid intake:
Therefore, the client's total fluid intake for the 12-hour shift is 1880 mL.
Correct Answer is ["24"]
Explanation
Calculations:
The heparin solution contains 25,000 units in 500 mL.
To deliver 1,200 units/hour, we need to find out how many mL will deliver this amount.
Set up a proportion:
25,000 units / 500 mL = 1,200 units / x mL
Cross-multiply:
25,000x = 1,200 x 500
Solve for x:
x = (1,200 x 500) / 25,000 = 24 mL/hr
The nurse should set the IV pump to deliver 24 mL/hr.
