A nurse is caring for a client who has major depressive disorder and is taking an antidepressant. The nurse should identify which of the following findings as the priority to report to the provider?

The nurse should identify the sudden increase in energy as the priority finding to report to the provider. This could be a sign of an emerging manic episode, especially if the client is taking an antidepressant alone without a mood stabilizer. It may indicate a switch to a manic state or the development of bipolar disorder. The provider needs to be informed promptly so that appropriate assessment and interventions can be implemented to ensure the client's safety and well-being.
