A nurse in a rehabilitation center is caring for a client who has bipolar disorder. Which of the following actions by the client indicates mania?

Choice A reason: Feelings of inferiority align with depression, not mania, in bipolar disorder, where self-esteem plummets, not elevates. Mania features grandiosity or confidence, opposite to this. This action reflects a low phase, so it doesn’t indicate mania here. Choice B reason: Constant talking (pressured speech) is a classic mania sign in bipolar disorder, driven by racing thoughts and high energy. It’s disruptive, persistent, and aligns with elevated mood states, distinguishing it from normal chatter. This behavior clearly indicates mania, making it correct. Choice C reason: Sleeping over 10 hours suggests hypersomnia, typical in bipolar depression, not mania, where sleep decreases (e.g., 3-4 hours). Mania energizes, not sedates. This action points to a depressive episode, so it’s not a mania indicator. Choice D reason: Memory loss may occur in bipolar from meds or chronicity, but it’s not specific to mania, where focus shifts rapidly, not blanks out. It’s more tied to depression or dementia. This doesn’t reflect mania’s hyperactive state, so it’s incorrect.
