A nurse is collecting data from a client who has bipolar disorder. Which of the following findings is the nurse's priority?

A. The client talks excessively: Pressured speech is a common manifestation of mania in bipolar disorder. While it requires monitoring, it does not pose an immediate threat to the client’s health. B. The client dresses in vivid, bright colors: Wearing bright or unusual clothing reflects the euphoric or expansive mood seen in mania. This behavior is not immediately harmful and does not take priority over basic physiological needs. C. The client refuses to eat: Refusal to eat can lead to malnutrition, dehydration, and electrolyte imbalances, which are life-threatening if not addressed promptly. Maintaining adequate nutrition and hydration is a priority over behavioral or mood-related symptoms. D. The client sleeps 6 hr at night: Reduced sleep is common during manic episodes but is not immediately life-threatening. Sleep deprivation should be monitored, but the client’s refusal to eat requires more urgent intervention.
