A nurse is preparing to administer digoxin 0.25 mg PO to a school-age child. Available is digoxin elixir 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["0.005"]

1. Determine the desired dose and the available concentration:

  • Desired dose: 0.25 mg
  • Available concentration: 50 mg/mL

2. Set up the calculation:

  • We need to find out how many mL contain 0.25 mg of digoxin. We can use the following formula:
    • (Desired Dose) / (Available Concentration) = Volume to Administer

3. Perform the calculation:

  • 0.25 mg / 50 mg/mL = 0.005 mL

4. Round the answer:

  • The answer is 0.005 mL.
  • Since the question asks to round to the nearest whole number and use a leading zero if it applies, and not use a trailing zero, and since this number is less than 1, we add a leading zero.
  • The answer is 0.005mL.

Therefore, the nurse should administer 0.005 mL of digoxin elixir.
