While talking with a client diagnosed with major depressive disorder, a nurse notices the client is unable to maintain eye contact.

The client's chin lowers to the chest.

The client looks at the floor.

Which aspect of communication has the nurse assessed?

Choice A rationale

Aversion therapy is a behavioral therapy that uses the principles of classical conditioning to help a client reduce or stop an undesirable behavior, such as alcohol consumption. It pairs the unwanted behavior with a noxious stimulus, which, in the case of disulfiram, is the unpleasant physical reaction (nausea, vomiting) caused by acetaldehyde accumulation from alcohol metabolism blockade. This creates a conditioned aversion to alcohol.

Choice B rationale

Biofeedback is a technique that teaches a client to control involuntary physiological responses, such as heart rate or muscle tension, by providing real-time visual or auditory feedback about these functions. It operates on the basis of operant conditioning, allowing the client to modify their responses to achieve a desired physical state, and it is not typically used to directly treat substance use disorder in this manner.

Choice C rationale

Flooding is an exposure-based behavioral therapy used primarily for anxiety disorders, such as phobias. It involves exposing the client to a maximally anxiety-provoking stimulus (the feared object or situation) for a prolonged period, preventing escape, which allows habituation and extinction of the conditioned fear response to occur. This is not the mechanism of action for disulfiram.

Choice D rationale

Dialectical behavior therapy (DBT) is a comprehensive, evidence-based psychotherapy originally developed for clients with borderline personality disorder. It combines cognitive-behavioral techniques with mindfulness and emotional regulation strategies. DBT is a structured, long-term approach focusing on skills training and is distinct from the pharmacologically-induced classical conditioning of aversion therapy.

Choice A rationale

Occasional sleeplessness and anxiety are common, transient responses to stress or life events and do not, in isolation, suggest a diagnosable mental illness. These symptoms are often within the normal spectrum of human emotional and physiological responses, reflecting coping mechanisms that do not necessarily constitute a pathological syndrome causing significant functional impairment.

Choice B rationale

The ability to differentiate between "as if" (e.g., imagination, metaphor) and "for real" (e.g., reality) demonstrates an intact reality testing capacity, which is a hallmark of mental health. Impaired reality testing, such as experiencing hallucinations or delusions, would be a much stronger indicator of a potential mental illness, particularly psychosis.

Choice C rationale

A consistently sad, discouraged, and hopeless mood that persists over time and potentially impairs daily functioning is a cardinal symptom complex of Major Depressive Disorder. This constellation of persistent negative affect and cognitive distortion significantly deviates from typical emotional responses and suggests a pathological change in mood regulation and perception.

Choice D rationale

Experiencing difficulty with major life decisions is a normal, albeit stressful, part of the human experience. Indecisiveness can stem from various non-pathological factors, such as fear of commitment or evaluating complex variables. It only becomes indicative of mental illness if it is severe, pervasive, and accompanied by other clinical features, like profound anxiety or depression.
