What is the most reliable method to verify the correct chemotherapy dose before administration?

• A. A two-person verification process against the prescription/order, including drug, dose, route, and patient identity
• B. A single clinician's review
• C. Verifying only against the drug name
• D. Checking the dose with the patient

Answer: (A)

Two-person independent verification against the prescription/order, including drug, dose, route, and patient identity, provides the strongest safeguard for chemotherapy dosing. This redundancy catches errors that a single reviewer might miss, such as miscalculation, mislabeling, or a mismatch between what was prescribed and what’s prepared. Verifying only the drug name or relying on a single clinician’s review can miss dose or route mistakes, and checking the dose with the patient doesn’t provide independent verification. By requiring two qualified people to confirm all critical elements and the patient’s identity, the process substantially reduces the risk of a dosing error before administration.
