A nurse is assessing a client who has bipolar disorder. Which of the following findings should the nurse identify as an indication that the client is experiencing acute mania?

A. Isolation is more characteristic of depressive episodes rather than mania. In acute mania, clients tend to be overly social and energetic, not isolative. B. While clients in mania may display excessive energy, writing a detailed daily schedule is not a typical symptom. Mania is more often associated with impulsiveness and a lack of focus. C. Refusing to engage in conversation would suggest withdrawal, which is common in depressive states, not mania. D. A lack of sleep is a hallmark symptom of acute mania, as individuals often feel energized and do not require the usual amount of rest, leading to sleep disturbances.
