When a hyperactive patient diagnosed with acute mania is hospitalized, what is the initial nursing intervention?

Rationale: A. Restraining should only be used as a last resort when the patient poses an imminent danger to self or others, not as an initial intervention. B. Allowing the patient to act out feelings without limits can lead to unsafe behaviors and escalate manic symptoms. C. Setting limits on behavior provides structure, maintains safety, and helps the patient with mania feel more secure and contained. D. Providing verbal instructions to remain calm is ineffective in acute mania, as the patient’s ability to process and follow directions is impaired.
