Which behavior by a client is most likely indicative of residual depressive symptoms while on antidepressants?

Taking long naps can be indicative of residual depressive symptoms while on antidepressants because it suggests a continued struggle with fatigue or lack of motivation, which are hallmark signs of depression. Even though the client is receiving treatment, the presence of excessive sleeping may reflect that the treatment is not fully alleviating the depressive symptoms. It suggests that the individual is not as functional or engaged in daily activities as one would hope, as they may turn to sleep as a way to escape from feelings of sadness or lethargy, which can still persist despite medication.

In contrast, increased social interaction and improved energy levels are positive signs often associated with effective treatment for depression. They indicate that the antidepressants are likely helping the individual engage more fully with life and their surroundings. Expressing negative feelings can also occur for various reasons, including during the process of therapy or as part of human emotional expression; however, it may not directly indicate that depressive symptoms are present when the individual is on medication. In summary, while other options reflect possible positive responses to treatment, taking long naps points to a potential lingering issue with depression.
