A nurse is caring for a client who has major depressive disorder. Which of the following findings should indicate to the nurse that the client’s condition is improving?

Choice A reason: Increased energy and motivation signal improvement in major depressive disorder, countering fatigue and anhedonia. Serotonin and norepinephrine rebalance, often from treatment, restores drive and engagement, reflecting neurochemical stabilization in the brain’s limbic system, critical for mood regulation and recovery. Choice B reason: Self-doubt in decision-making reflects persistent depressive symptoms, like low self-esteem and cognitive impairment. Negative thought patterns, driven by altered prefrontal cortex activity, indicate ongoing depression, not improvement, requiring adjusted interventions to address these neurocognitive deficits in major depressive disorder. Choice C reason: Sleeping 12 hours daily indicates hypersomnia, a depressive symptom, suggesting no improvement. Disrupted circadian rhythms and serotonin dysregulation cause excessive sleep, contrasting with recovery signs like normalized sleep patterns. This reflects persistent neurochemical imbalances hindering mood stabilization in depression. Choice D reason: Social isolation is a core depressive symptom, driven by anhedonia and low mood, indicating no improvement. Withdrawal reflects ongoing dopamine and serotonin imbalances, preventing social engagement. Recovery involves increased interaction, making isolation a sign of persistent major depressive disorder.
