Choice A rationale:

Increased sleep duration is not a characteristic of manic episodes in bipolar disorder. In fact, decreased need for sleep is a common symptom of manic episodes. Individuals experiencing a manic episode often report feeling restless and having a decreased need for sleep.

Choice B rationale:

Reduced goal-directed activity is not typical of manic episodes. During manic episodes, individuals often exhibit heightened goal-directed activity, excessive energy, and increased involvement in various activities. This can lead to a decreased ability to focus on one task at a time.

Choice C rationale:

Correct Choice In a manic episode, individuals may display a decreased need for social interaction. They might engage in excessive socializing, seek out new social interactions, and exhibit a heightened level of confidence in their ability to engage with others. This increased sociability can sometimes be characterized by rapid speech and impulsiveness in social situations.

Choice D rationale:

Feelings of sadness and hopelessness are not indicative of manic episodes. These emotions are more aligned with depressive episodes in bipolar disorder rather than manic ones. Manic episodes are characterized by elevated mood, increased energy, and a sense of euphoria or grandiosity.
