Step-by-step explanation:
The first action that the charge nurse should take in this situation is to confront the staff nurse about the discrepancy. This is important to address the issue and gather more information. Confronting the staff nurse allows for clarification and resolution of the situation, ensuring accurate documentation and patient safety.
Once the confrontation has taken place, it may be necessary to complete an incident report detailing the discrepancy. Incident reports are used to document adverse events and should be completed to ensure that the incident is properly investigated and preventive measures can be implemented.
