A nurse receives a handwritten medication order that is partially illegible and contains an abbreviation not on The Joint Commission's approved list. What is the nurse's best initial action to ensure safe medication administration?

A. Contact the prescriber to clarify the unclear parts and confirm the intended medication and dosage is correct because patient safety is the highest priority. Illegible orders or unapproved abbreviations can lead to medication errors, overdosing, or administering the wrong drug. The nurse must verify directly with the prescriber before administering any medication, following the “right drug, right dose, right route, right time” principles. B. Discard the order and request a new one from the prescriber without attempting clarification is incorrect because discarding the order is unnecessary if clarification can be obtained. Direct communication with the prescriber ensures accuracy without causing unnecessary delays. C. Administer the medication based on the most common dosage and route for that medication to avoid delay is incorrect because guessing a dose is extremely unsafe and violates professional and legal standards. Even small deviations from intended dosing can cause serious harm. D. Consult the pharmacy to interpret the order and proceed with their recommendation is partially incorrect because while pharmacists can assist, the nurse cannot administer a medication without prescriber confirmation. Clarification must come from the prescriber, especially when the order is illegible or contains unapproved abbreviations.
