Final answer:
The PN should observe the client, assess for safety, record the event, then consider engaging in a supportive manner if appropriate, while maintaining client dignity and a therapeutic environment.
Step-by-step explanation:
The practical nurse (PN) observes a client with the diagnosis of schizophrenia sitting all alone and talking quietly. Which action should the PN take? The appropriate action for the PN in this situation would be to discreetly observe the client, assess the behavior for safety and therapeutic needs, and then record the event in the client's medical records. It is important not to disturb the client immediately if they are not exhibiting signs of distress or a threat to their safety. After observation, the PN can consider engaging the client in a nonthreatening and supportive manner, if deemed appropriate. The overall approach should be patient-centered, ensuring that the client's dignity and need for a therapeutic environment are maintained.
