Final answer:
The appropriate response by the nurse would be to ask the client why they believe the FBI is monitoring their calls to gather more information and assess their thought process.
Step-by-step explanation:
The appropriate response by the nurse in this situation would be to ask the client why they believe the FBI is monitoring their calls.
By asking the client why they hold this belief, the nurse can gather more information about the client's thought process and assess whether it is a symptom of their schizophrenia. This response shows empathy and respect for the client's perspective while also ensuring a thorough assessment is conducted.
Telling the client that the FBI is not monitoring their calls or assuring them that their calls are not being monitored may be interpreted as dismissing or invalidating the client's experience and feelings, which can hinder the therapeutic relationship and the client's trust in the nurse.
