Before administering any medication, what two critical patient identifiers should you verify?

• A. Name and room number
• B. Date of birth and patient address
• C. Name and date of birth
• D. Name and date of birth (or medical record number)

Answer: (D)

Two identifiers ensure you’re matching the right person to the right chart before giving any medication. The most reliable pairing is the patient’s name plus another unique data point such as date of birth or the medical record number. Verifying both confirms you’re treating the correct individual and helps prevent medication errors.

Room numbers aren’t safe identifiers because rooms can change and aren’t unique to a person. Addresses aren’t consistently tied to the patient in the moment of medication administration. Date of birth alone isn’t enough to distinguish between people with the same name, so a second identifier is needed. If available, the medical record number provides a hospital-specific unique identifier that can substitute for date of birth to verify the patient.
