Final answer:
The correct nursing response is 'D. "I can see why you feel that way."' because it acknowledges the feelings of a client with schizophrenia without reinforcing the delusion, maintaining therapeutic rapport.
Step-by-step explanation:
The appropriate nursing response to a client diagnosed with schizophrenia who believes their roommate is plotting against them should provide comfort, validate their feelings, without reinforcing the delusion. Therefore, the correct answer is D. "I can see why you feel that way."
This response acknowledges the client's feelings and can facilitate a therapeutic relationship, allowing for further exploration of those feelings in a safe environment. It's important to respond with empathy and maintain the therapeutic rapport without agreeing with the delusion.
Answers such as "I find that hard to believe" might seem dismissive, "What would make you think such a thing?" could be perceived as confrontational, and "I know your roommate. He would do no such thing" directly invalidates the client's experience and could be confrontational as well.
