A nurse at a community mental health center is caring for a client who has bipolar disorder. The nurse should recognize that which of the following statements is an indication that the client is in the manic phase?

A. "I was able to pay my bills last month, but this month, I fell behind.": Difficulty managing finances can indicate functional impairment, but it is nonspecific and could occur during depressive episodes or life stressors rather than mania. B. "I've been crying a lot in the past 3 days because my cat died.": Persistent crying and sadness reflect depressive symptoms and situational grief rather than the elevated or irritable mood, increased energy, and hyperactivity seen in mania. C. "I haven't been able to stop talking for the past couple of days.": Pressured speech and excessive talking are hallmark manifestations of the manic phase of bipolar disorder. This indicates heightened energy, distractibility, and reduced need for sleep associated with mania. D. "My family says I'm thinking clearly now that I'm taking my medication.": Improved cognition and stability suggest effective management of symptoms, possibly after treatment for mania or depression, but it does not indicate current manic behavior.
