A nurse is preparing to discharge a client who has depression. Which of the following information should the nurse plan to reinforce with the client regarding relapse?

Introduction: Major depressive disorder involves persistent maladaptive neurobiological alterations resulting in low mood and anhedonia. Relapse prevention focuses on identifying individual triggers to maintain emotional homeostasis and prevent symptomatic recurrence through early clinical intervention. A. Systematic desensitization is a behavioral therapy primarily utilized for phobic disorders or anxiety by gradually exposing the client to a feared stimulus. It is not a standard evidence-based intervention for the prevention of relapse in major depressive disorder, which requires cognitive-behavioral or pharmacological maintenance strategies instead. B. Identifying personal reactions to stressors is a critical component of relapse prevention. It allows the client to recognize early warning signs of a depressive episode, facilitating the implementation of coping mechanisms before symptoms become debilitating. This self-awareness is essential for maintaining long-term psychological stability and autonomy. C. Antidepressant medications, such as Selective Serotonin Reuptake Inhibitors (SSRIs), typically require a therapeutic window of 2 to 4 weeks to achieve symptomatic relief. Telling a client they will feel better in a few days is scientifically inaccurate and can lead to non-compliance if expectations are not met. D. Snapping a rubber band on the wrist is a form of aversion therapy or a grounding technique often used for impulse control or self-harm redirection. While it may provide a temporary distraction from intrusive thoughts, it does not address the underlying pathophysiology of depression or serve as a comprehensive relapse prevention strategy.
