Final answer:
The nurse should inform the supervisor about their suspicion that the co-worker has an alcohol use disorder. Prioritizing patient safety is important.
Step-by-step explanation:
The nurse should inform the supervisor about their suspicion that the co-worker has an alcohol use disorder. It is important to prioritize patient safety and to ensure that the co-worker receives the necessary help and support. By notifying the supervisor, proper actions can be taken to address the situation.
Taking matters into the nurse's own hands, such as giving medications or warning the co-worker, may not be the appropriate course of action. It is important to involve the supervisor who can handle the situation professionally and ensure the well-being of both the co-worker and patients.
