How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it apples. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["4"]

The nurse should administer 4 mL of levothyroxine.

Calculations:

Convert 0.4 mg to mcg: 0.4 mg x 1000 mcg/mg = 400 mcg

Desired dose = 400 mcg

Concentration = 100 mcg/mL

Volume = Desired dose / Concentration = 400 mcg / 100 mcg/mL = 4 mL

Correct Answer is ["2"]

Explanation

Understanding the problem

We need to administer 4000 mcg of Rosuvastatin.

The available tablets are 2 mg each.

We need to determine the number of tablets to administer.

Step-by-step calculation

Convert mcg to mg:

1 mg = 1000 mcg

4000 mcg = 4 mg

Calculate the number of tablets:

Number of tablets = Desired dose (mg) / Tablet strength (mg) = 4 mg / 2 mg/tablet = 2 tablets

Therefore, the nurse should administer 2 tablets of Rosuvastatin.

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.
