Final answer:
The solution to patient identifiers error by nurses is to use bar coding to identify both the patient and the medication, which helps ensure accurate medication administration.
Step-by-step explanation:
A solution to a patient identifiers error caused by nurses would be B. Use bar coding to identify the patient and medication. Bar coding systems can significantly reduce human errors in patient identification by scanning the patient's wristband and the medication to be administered, ensuring that the correct patient receives the correct medication at the correct time. This technology-based approach to patient safety aligns with best practices in medication administration and can be integrated into the electronic health record (EHR) systems for real-time verification and documentation.
