A 45-year-old client with a delusional disorder believes that their neighbor is spying on them through hidden cameras in their home. The client is anxious but willing to discuss their belief. What is the most appropriate nursing response to support reality testing?

Choice A reason: Directly rejecting the belief is non-therapeutic and may increase defensiveness, damaging trust. Choice B reason: Telling the client to stop worrying invalidates their feelings and dismisses the emotional impact of the delusion. Choice C reason: Participating in the delusion by “looking for cameras” reinforces the false belief, which is not supportive of reality testing. Choice D reason: Acknowledging the client’s fear while gently presenting reality and shifting toward problem-solving helps maintain trust and supports reality testing.
