Final answer:
The best statement a nurse can make to a client showing severe panic and delusional thoughts is one that conveys empathy, reassurance, and support, without validating the delusion.
Step-by-step explanation:
To initiate a therapeutic relationship with a client on an inpatient psychiatric unit who exhibits severe panic, it is essential to create an environment that conveys safety, understanding, and a willingness to help. The correct approach should involve acknowledging the client's distress and offering support and assistance. Among the choices provided, the best statement a nurse can make to start building a therapeutic relationship with the client expressing severe panic and delusional thoughts about being harmed by the police would be: "You're having very frightening thoughts. I'll help you find ways to cope with this scary thinking." This statement conveys empathy and reassurance, and it directly addresses the patient's immediate emotional experience without confirming or denying the delusion, thus helping to establish trust and rapport.
