What is the nurse's duty when another nurse makes an error?

When a nurse observes another nurse making an error, their duty is to prioritize patient safety by immediately addressing the situation. This involves informing the nurse of the mistake and, if necessary, taking steps to mitigate any potential harm to the patient. Additionally, the observing nurse should report the incident to the appropriate supervisor or follow institutional protocols to ensure proper documentation and review of the error. Ultimately, collaboration and communication are key to fostering a safe healthcare environment.
