The question bank is the fastest way to start, but PMHNP Helper also includes board-review planning, student resources, and plain-English guidance for psychiatric nurse practitioner students who are still learning the exam landscape.
A 47-year-old female has been in remission from major depressive disorder for the past two years on sertraline 150 mg daily. This was her third lifetime depressive episode. Her first episode occurred at age 26 following a significant interpersonal loss, her second at age 38 during perimenopause, and the most recent episode at age 45 presented with melancholic features including profound psychomotor retardation, early morning awakening, and 15-pound weight loss. Each episode was severe, with the second and third requiring psychiatric hospitalization. She has no residual depressive symptoms, a PHQ-9 score of 2, and reports functioning well in all domains. She asks whether she can discontinue sertraline, stating she feels she no longer needs medication. The PMHNP evaluates whether long-term continuation or discontinuation is indicated. Which evaluation conclusion is most accurate?
Explanation
Indefinite antidepressant maintenance at the full remission dose is recommended for patients with three or more major depressive episodes, particularly when episodes have been severe, required hospitalization, or displayed melancholic features. Current remission represents successful treatment rather than evidence that medication is no longer needed.
Key Takeaway
Three or more major depressive episodes, increasing severity, melancholic features, and prior hospitalizations support indefinite antidepressant continuation at the full dose that achieved remission, as recurrence risk remains elevated across the lifetime.
