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?

A. The client has a sudden increase in energy: A sudden increase in energy in a client with major depressive disorder can indicate an elevated risk for suicidal behavior, especially if the client previously had low motivation or lethargy. This change is an urgent safety concern and should be reported immediately. B. The client reports a change in sleeping patterns: Changes in sleep are common in depression and with antidepressant therapy. While important to monitor, they are not as immediately life-threatening as sudden energy changes that could precede suicidal actions. C. The client is withdrawn and uncommunicative: Social withdrawal is a common symptom of depression. While concerning, it does not require the same urgent response as a sudden increase in energy that could indicate imminent risk. D. The client neglects personal hygiene: Poor self-care is typical in depression and should be addressed in ongoing care, but it does not present the same immediate risk as potential suicidal behavior.
