What should be the first action of the nurse when finding a client lying on the floor?

The first action a nurse should take when finding a client lying on the floor is to establish if the client is responsive. This step is crucial because it assesses the client's immediate condition and determines the level of consciousness. By checking responsiveness, the nurse can quickly identify if the client requires urgent medical attention or if they are stable enough to communicate about what occurred.

This initial assessment helps guide the subsequent actions, such as whether to call for help, assist the client back to bed, or inquire about the incident. Establishing responsiveness also allows the nurse to evaluate the potential for injuries, such as head trauma, which may require specific interventions. Thus, ensuring the client's safety and well-being is priority number one.
