A nurse is evaluating a client who has a new diagnosis of bipolar disorder. Which of the following behaviors supports this diagnosis?

• A. Excessive dietary intake
• B. Paranoid thinking
• C. Ritualistic actions
• D. Constant talking

Answer: (D)

In bipolar disorder, mania often brings a marked increase in activity and energy, which shows up as pressured, rapid, and nonstop talking. This persistent, nonstop talking reflects the dizzying pace of thoughts and the urge to express them without pause, making it a classic sign of a manic state and, when observed with other symptoms, supports the diagnosis.

Excessive dietary intake isn’t a defining feature of mania and can occur in various contexts. Paranoid thinking can appear in mania with psychotic features but isn’t the core indicator of a manic episode. Ritualistic actions point more toward obsessive-compulsive patterns than mania. So, the nonstop talking most strongly aligns with manic behavior.
