What action should a housekeeper take if a resident is asleep and does not respond when the housekeeper knocks on the door?

The appropriate action for the housekeeper in this situation is to notify the nursing staff before entering the room. This is crucial because it respects the resident's privacy and personal space, ensuring that any potential needs or responses from the resident are accounted for. By involving nursing staff, the housekeeper allows professionals who are trained to assess the situation to determine if it is safe and appropriate to enter the room. This not only prioritizes the resident's well-being but also adheres to protocols that are established in healthcare settings to ensure safety and respect for all residents.
