During dose verification, which elements should be compared against the prescription/order?

• A. The patient's age and weight
• B. The nurse's initials
• C. Drug, dose, route, and patient identity
• D. The physician's favorite color

Answer: (C)

The main point is to verify that the medication being given matches the clinician’s order in four critical aspects: the drug, the dose, the route, and the patient identity. Verifying the drug ensures you administer the exact medication intended and helps prevent mix-ups with similar-sounding names. Checking the dose confirms the amount and units are correct and align with what was ordered and what the preparation contains, which is especially vital in chemotherapy where dosing is precise and may be based on weight or body surface area. Confirming the route ensures the medication is given by the intended method (for example, IV versus oral), since changing the route can alter absorption, efficacy, and safety. Verifying the patient identity using two identifiers helps ensure the right person receives the right treatment, avoiding dangerous mix-ups.

Age and weight can influence dosing calculations, but they are not the elements you compare against the prescription during the dose-verification step itself. Nursing initials are about documentation, and a physician’s favorite color is unrelated to safe medication administration.
