A practical nurse (PN) is caring for clients on a locked Alzheimer's unit. Which client situation requires the PN's immediate attention?

A. Move the client who is knocking on the exit door and trying to get out: While this client’s behavior requires supervision to prevent elopement, there is no immediate physical harm, so it is not the highest priority. B. Remind a confused client of today's date and the time lunch will be served: Reorientation is important for cognitive support, but it does not involve immediate risk of injury. C. Talk to a client who is wandering the halls looking in everyone's room: Wandering poses some safety risks, but unless the client is in immediate danger, it is not as urgent as assisting a client on the floor. D. Assist a client who is lying on the dayroom floor to sit in the chair: A client lying on the floor may have fallen and could have injuries or be at risk for further harm. Immediate attention is needed to assess for injury, prevent complications, and provide safe positioning.
