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 41-year-old woman is being followed in an outpatient psychiatric clinic for major depressive disorder and comorbid generalized anxiety disorder. She was started on escitalopram 10 mg daily 8 weeks ago. At today's visit, her PHQ-9 score is 8 (down from 17 at baseline) and her GAD-7 score is 6 (down from 14 at baseline). She reports feeling better but still has residual low energy, mild worry about work, and occasional difficulty falling asleep. Using measurement-based care principles, what is the most appropriate next step?
Explanation
Measurement-based care relies on critical thresholds: PHQ-9 remission is below 5, response is a 50% or greater reduction; GAD-7 remission is below 5. When a patient responds but does not remit, the appropriate next step is dose optimization of the current effective medication. Distinguishing response from remission and targeting remission as the treatment goal are essential clinical principles.
Key Takeaway
In measurement-based care, a PHQ-9 of 5 or above indicates residual depression requiring dose optimization rather than maintenance, and remission, not just response, is the treatment target.
