A nurse prepares the plan of care for a patient experiencing an acute manic episode. Which nursing diagnoses are most likely? (Select all that apply).

Rationale: A. Social isolation is more typical in depression or withdrawal, not acute mania, where patients are often excessively social or intrusive. B. Impaired mood regulation is characteristic of mania, involving mood swings, irritability, and poor impulse control. C. Imbalanced nutrition: more than body requirements is unlikely during mania; patients often have decreased appetite. D. Chronic confusion is not typical in acute mania; cognitive impairment may be present but is usually not chronic. E. Sleep deprivation is common in manic episodes due to decreased need for sleep and hyperactivity.
