Which scenario best demonstrates appropriate use of two-person verification in chemotherapy administration?

• A. Two clinicians independently verify patient, drug, dose, route, and time against the order prior to administration.
• B. One clinician verifies only the drug.
• C. Verification is optional for routine drugs.
• D. Verification occurs after administration.

Answer: (A)

The essential safety step is two-person verification before chemotherapy administration, where two clinicians independently confirm every critical detail to ensure the right patient receives the right drug, dose, route, and time. In practice, this means both clinicians verify the patient’s identity, the drug name, the prescribed dose, the route of administration, and the scheduled time against the order and the chemotherapy label, and they do this independently to catch potential discrepancies. This check is done prior to giving the infusion, not after, and it helps catch errors that could cause severe harm given chemotherapy’s high toxicity and narrow therapeutic window. Documentation of the verification is also important to show the safeguard was completed.

Why this is the best approach: it provides a robust safeguard by requiring a second, independent review of all elements that could be misread or miscalculated, minimizing the chance that a wrong drug, dose, or timing is given. The other scenarios fail to prevent harm: verifying only the drug omits dose and route checks; making verification optional loosens a critical safety barrier; and verifying after administration does nothing to avert potential injury.
