The nurse is performing intake interviews at a psychiatric clinic. A client with a known history of drug abuse reports having had a heart attack four years ago. Use of which substance places the client at highest risk for myocardial infarction?

A. "The snakes on the wall are going to eat me." describes a visual hallucination, not a delusion. Hallucinations involve false sensory perceptions, such as seeing things that are not present. While hallucinations are common in schizophrenia, this statement does not indicate a delusion.

B. "The nurse at night is trying to poison me with pills." confirms a delusion, specifically a paranoid delusion. Delusions are fixed, false beliefs that are not based in reality and cannot be changed by logic or reasoning. In this case, the client irrationally believes that the nurse is trying to harm them, which is a classic symptom of schizophrenia.

C. "The voices are telling me to kill the next person I see." describes an auditory hallucination, which involves hearing voices or sounds that are not real. While auditory hallucinations are a common symptom of schizophrenia, this statement does not indicate a delusion.

D. "The fire is burning my skin away right now." describes a tactile hallucination, where the client falsely perceives sensations (e.g., burning). This is another form of hallucination, not a delusion, as it involves sensory misperception rather than a false belief.

- Choice A Rationale: Determining the type and size of the locks does not address the client's anxiety or the behavior that is impacting their daily functioning. This action might inadvertently reinforce the client's focus on the locks rather than addressing the underlying issue.
- Choice B Rationale: Planning a list of activities to be carried out daily can help the client establish a routine, which may reduce anxiety and the need for repetitive checking. This approach encourages the client to focus on the day's tasks and can provide a sense of control and accomplishment.
- Choice C Rationale: Discussing checking the time frequently does not directly address the client's repetitive behavior or the associated anxiety. While time management may be part of a broader treatment plan, it is not the most immediate action the nurse should take.
- Choice D Rationale: Ask the client why the locks are checked so frequently is not therapeutic and may put the client on the defensive. Clients with obsessive-compulsive behaviors often cannot explain why they perform rituals, as the behavior is driven by anxiety rather than logic. Asking "why" may increase frustration without helping to address the behavior.
