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.)
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.

Explanation
Identify the given information:
Dose of midazolam: 3 mg
Concentration of midazolam solution: 5 mg/mL
Calculate the volume of midazolam to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 3 mg / 5 mg/mL
Calculate the result:
Volume = 0.6 mL
Correct Answer is ["2.5"]
Explanation
Identify the given information:
Dose of cefazolin: 835 mg
Concentration of cefazolin: 330 mg/mL
Calculate the volume of cefazolin to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 835 mg / 330 mg/mL
Calculate the result:
Volume ≈ 2.53 mL
Round the answer to the nearest tenth:
Volume ≈ 2.5 mL
