When providing education to a client with bipolar disorder and their family, the nurse should emphasize which symptom as the most significant indicator for mania?

Choice A reason: Increased energy can be an early sign of mania, but by itself it is not the most significant indicator. Many conditions can cause increased energy, so it is not specific enough to identify mania. Choice B reason: Pleasure and motivation for new endeavors can be normal experiences and do not necessarily indicate mania. In mania, these feelings are excessive and paired with risky behaviors, but alone they are not the most significant indicator. Choice C reason: Leaving a good job to start a new business may reflect impulsivity, but this is a behavioral consequence rather than a core symptom. It is not the most reliable indicator of mania. Choice D reason: Decreased need for sleep and racing thoughts are hallmark symptoms of mania. Clients may sleep only a few hours yet feel rested, and their thoughts may be rapid and difficult to follow. These symptoms are the most significant indicators of mania.
