A nurse is caring for a client who has schizophrenia and notices changes in the client's behavior. Which of the following behaviors is the nurse's priority to report to the provider?

Choice A reason: Eating half of meals indicates reduced intake but is not immediately dangerous. It requires monitoring but is not the priority. Choice B reason: Diminished facial affect is a negative symptom of schizophrenia. While important to document, it does not pose immediate risk. Choice C reason: Decreased energy level is nonspecific and could be related to medication or illness. It is not urgent compared to bizarre behaviors. Choice D reason: Bizarre behaviors are a positive symptom that may indicate worsening psychosis. They can pose safety risks to the client or others, making them the priority to report.
