Which scenario best illustrates a three-way match in BCMA?

• A. Verifying patient identity, medication, and dose through barcode scans prior to administration.
• B. Scanning only the patient ID.
• C. Verifying only the medication label.
• D. Approving medication administration without verification.

Answer: (A)

Three-way match means confirming three critical elements before giving medication: the patient, the drug, and the dose. In BCMA, this is done by scanning the patient’s barcode to verify identity, scanning the medication barcode to verify the exact drug, and scanning the dose/strength to confirm it matches the prescription. When all three checks are performed via barcode scans prior to administration, you ensure the right patient receives the right medication in the correct amount, aligning with the order and reducing the chance of errors.

This scenario best illustrates that process because it requires verification of patient identity, the medication, and the dose in one coordinated step. Verifying only one element or bypassing verification would not provide the complete safety check needed to prevent mismatches or dosing errors.
