Which patient identifiers should always be checked before giving a medication?

• A. Full name and date of birth; cross-check with MAR
• B. Room number only
• C. Diagnosis
• D. Insurance number

Answer: (A)

Verifying the patient identity with two reliable identifiers before giving medication is a vital safety step. The best practice is to use the patient’s full name and date of birth and cross-check those details against the medication administration record. This two-identifier check links the exact order to the correct person, ensuring the right drug, dose, and route are given to the right patient.

Room number alone isn’t reliable because patients move between rooms and different people may share a room at times, so a room alone can’t uniquely identify someone. Diagnosis isn’t sufficient because many patients can have the same diagnosis, and it doesn’t distinguish individuals. An insurance number isn’t used at the bedside for medication administration and may not be readily accessible or appropriate to reveal in that moment.

Using the two identifiers with the MAR minimizes mix-ups and supports safe administration, aligning with the standard right-patient safety rule. If doubt ever arises, confirm with the patient or a trusted chart source and follow policy for additional verification.
