Correct Answer is ["4.8"]

Explanation

Understanding the problem

We need to administer 240 mg of hydrocortisone.

The reconstituted solution has a concentration of 50 mg/mL.

We need to determine the volume to administer.

Step-by-step calculation

Use the formula:

Volume (mL) = Desired dose (mg) / Concentration (mg/mL)

Substitute the values:

Volume (mL) = 240 mg / 50 mg/mL

Calculate the volume:

Volume (mL) = 4.8 mL

Therefore, the nurse should administer 4.8 mL of the reconstituted hydrocortisone solution.

A. Aspirin 81 mg PO daily B. Acetaminophen 1000 mg PO every 6 hours prn for mild-moderate pain C. Ibuprofen 400 mg PO every 4 hours prn for mild-moderate pain D. Amoxilin 250 mg tablet PO X7 days

Correct Answer is D

Explanation

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.
