What should a nurse do before entering an agitated patient's room?

Before entering an agitated patient's room, it is crucial for a nurse to identify a route of escape. This proactive measure ensures the safety of the nurse and other staff members should the situation escalate. Agitation in patients can lead to unpredictable behavior, and being prepared to exit quickly is a key aspect of maintaining safety in a potentially volatile environment. By having an escape plan, the nurse can respond more effectively to any sudden changes in the patient's behavior.

The other choices, while they may hold some importance, do not prioritize immediate safety in the same way. Preparing medication can be beneficial but should ideally occur when the nurse is in a safe position. Discussing plans with family can enhance understanding and support for the patient but does not directly address the urgent need for safety in the moment. Checking the patient's chart for history is important for clinical decision-making but might not be the best initial action when entering a potentially dangerous situation. Safety must always come first in emergency nursing scenarios.
