Final answer:
The nurse should report it to the CNO immediately, and then discuss the matter with the healthcare team. Speaking to the nurse regarding the matter is also important, but should be done after reporting it to the CNO.
Step-by-step explanation:
The first action the nurse should take is to report it to the Chief Nursing Officer (CNO) immediately. This is important because it ensures that the incident is documented and proper investigation can take place. The CNO will have the authority to address the situation appropriately.
While it may be necessary to speak to the nurse regarding the matter at some point, it is crucial to involve the CNO first to ensure the incident is properly handled.
Discussing the matter with the healthcare team should also be done, but after the incident has been reported to the CNO.
