A nurse on a unit frequently administers fractional doses of medication but is not confident in math. What is her best action?

• A. Always have a colleague check the calculations until confidence is achieved
• B. Stop giving fractional doses
• C. Double the calculated dose
• D. Guess and proceed

Answer: (A)

Accurate dose calculation is essential, and when fractions are involved, the risk of miscalculation increases. The best action is to have a colleague independently verify the calculations until you feel confident. This two-person check serves as a safety net, catching errors you might miss and reinforcing correct methods, such as using dimensional analysis, calculators, and reference resources. It’s a standard nursing practice to ensure patient safety before administering medications. Stopping fractional doses isn’t a solution because it can deprive patients of needed therapy; doubling the dose can cause harm; and guessing is never acceptable. If help isn’t immediately available, use available tools and resources (pharmacist, approved calculators, and references) and document the verification process.
