The nurse is caring for a client experiencing acute alcohol withdrawal. The nurse understands that safe withdrawal is usually accomplished by administering which class of medication to the client?

Choice A reason: The statement "I really thought you would make it" is a non-therapeutic response that inadvertently reinforces the client's sense of shame and failure by expressing disappointment. This response introduces the nurse's personal expectations and emotional reaction into the therapeutic encounter, which shifts focus from the client's needs to the nurse's feelings. It may deepen the client's sense of inadequacy and guilt, which are emotional states known to perpetuate the cycle of relapse and avoidance of treatment. Therapeutic communication in the context of substance use disorder requires non-judgmental, supportive engagement focused on the client's experience rather than the nurse's expectations.

Choice B reason: Asking "Why did you start drinking again?" is a confrontational and potentially judgmental question framed in a manner that may imply blame or deficiency in the client's willpower or decision-making. The use of "why" in this context may provoke defensiveness, increase shame, and discourage honest communication. Furthermore, this question presupposes that the client made a voluntary and fully informed choice to relapse, which does not account for the neurobiological mechanisms of addiction, including compulsive craving, impaired prefrontal executive function, and conditioned cue-triggered responses. This response is not consistent with motivational interviewing or therapeutic communication principles for substance use disorder management.

Choice C reason: While the statement "You have nothing to be ashamed of" is intended to be reassuring and reduce the client's shame, it is a form of false or premature reassurance that invalidates the client's expressed emotional experience. Telling the client that they have nothing to be ashamed of without exploring the underlying experience of shame may feel dismissive or superficial, particularly for a client who has been managing shame as part of their recovery journey. More therapeutically effective approaches acknowledge the client's feelings as valid while gently redirecting the conversation toward understanding and support rather than simply negating the emotion.

Choice D reason: Responding with "Tell me what has happened since your last admission" is the most therapeutically appropriate nursing response. This open-ended statement accomplishes multiple therapeutic goals simultaneously: it acknowledges the client's readmission without judgment or blame, invites the client to share their narrative in their own words, facilitates therapeutic alliance through active listening and genuine interest, and gathers clinically relevant information about the circumstances of relapse, which is essential for individualized treatment planning. This approach is consistent with motivational interviewing principles, which emphasize empathic, non-confrontational exploration of the client's experience to facilitate internal motivation for change.

Choice A reason: Current substance use is a well-established and clinically significant risk factor for the development and perpetuation of major depressive disorder. Substances including alcohol, opioids, stimulants, and cannabis have direct neurobiological effects on monoamine neurotransmitter systems, including serotonergic, dopaminergic, and noradrenergic pathways, which are central to mood regulation. Chronic substance use leads to dysregulation of these systems, neuroinflammation, and disruption of the hypothalamic-pituitary-adrenal (HPA) axis, all of which predispose to or worsen depressive symptomatology. Comorbid substance use disorder and major depressive disorder represent a highly prevalent and bidirectionally reinforcing dual diagnosis.

Choice B reason: A lack of coping ability is a recognized psychosocial risk factor for depressive disorders. Coping skills mediate the relationship between stressors and their psychological impact. Individuals who lack effective adaptive coping strategies — such as problem-solving, cognitive reframing, emotional regulation, and help-seeking — are more vulnerable to the persistent psychological distress that can precipitate and maintain clinical depression. Poor coping is associated with rumination, learned helplessness, and passive avoidance, all of which are cognitive and behavioral mechanisms strongly implicated in the etiology of depressive disorders. Building coping capacity is therefore a key component of both prevention and treatment.

Choice C reason: A responsive support system is a protective factor against the development of depression, not a risk factor. Social support buffers the negative psychological effects of stressful life events, provides emotional validation and practical assistance, reduces feelings of isolation, and promotes adaptive coping. Research consistently demonstrates that individuals with strong, responsive social support networks have significantly lower rates of major depressive disorder compared to those who are socially isolated. A responsive support system therefore does not belong among the risk factors associated with depression and is correctly excluded from the correct answer set.

Choice D reason: Prior episodes of depression represent one of the most robust and clinically significant risk factors for future depressive episodes. The concept of episode sensitization or "kindling" in affective disorders suggests that each successive episode of depression lowers the threshold for subsequent episodes, requiring progressively less severe external stressors to trigger recurrence. The number of previous episodes is directly correlated with recurrence risk, with individuals who have experienced 3 or more episodes of major depression having a recurrence rate exceeding 90%. This makes prior depressive episodes a critical factor in longitudinal risk assessment and treatment planning.

Choice E reason: A family history of depressive disorder is a well-established genetic and epidemiological risk factor for major depressive disorder. Twin studies estimate the heritability of major depression at approximately 37%, with first-degree relatives of individuals with MDD having a 2 to 3 times higher lifetime risk than the general population. The specific genetic variants implicated include polymorphisms in the serotonin transporter gene (SLC6A4), brain-derived neurotrophic factor (BDNF) gene, and genes related to the HPA axis and circadian regulation. Family history also contributes to risk through shared environmental exposures and modeled behavioral patterns, making it both a genetic and environmental risk factor.

Choice F reason: The presence of life and environmental stressors is a foundational risk factor in the biopsychosocial model of depression etiology. Adverse life events — including trauma, loss, financial hardship, interpersonal conflict, and occupational stress — activate the HPA axis, elevating cortisol levels and promoting neurobiological changes associated with depression, including hippocampal atrophy, reduced neurogenesis, and altered serotonergic and dopaminergic signaling. The diathesis-stress model proposes that environmental stressors interact with biological vulnerability to precipitate depressive episodes. Chronic and cumulative stressors are particularly harmful, as they sustain HPA axis activation beyond the individual's adaptive capacity.
