Practice Question
A nurse is preparing a medication and calculates the dosage as 6.25 mL. Rounding this amount to the nearest tenth, the nurse should administer how many mL?
Answer Choices:
Correct Answer:
6.3
Rationale:
✅Rounding rules in drug calculations require rounding to the nearest tenth when working with liquid medications measured in milliliters.
✅The nurse calculates 6.25 mL; since the hundredths place (5) is equal to or greater than 5, the tenth place is rounded up to 6.3 mL.
✅This ensures the dose is both safe and accurate, avoiding under- or overdosing.
✅Using a leading zero (0.3) is always correct to avoid misinterpretation, while no trailing zero prevents dangerous dosing errors.
✅Proper rounding is part of the “rights of medication administration”, ensuring client safety by verifying dose accuracy.
