Which items are verified in two-person verification before chemotherapy administration?

• A. Patient, drug, dose, route, and time.
• B. Patient only.
• C. Drug and dose only.
• D. Time only.

Answer: (A)

Two-person verification is a safety check used before administering chemotherapy to catch errors before they reach the patient. The essential elements both clinicians must verify are the patient identity, the drug name, the dose, the route of administration, and the time of administration. Confirming all five together ensures the right patient receives the correct drug in the correct dose, by the correct method, at the correct time. Missing any part of this check could allow a serious error, given chemotherapy’s narrow therapeutic index and potential for severe toxicity. This is why the best practice is to verify the five elements in unison before starting the infusion.
