Eric McMaster age 24,is known to be dependent on a variety of chemical substances, including alcohol and cocaine.Which of the following statements is an example of the most common defense mechanism employed by those dependent on chemical substances?

Reasoning:

Choice A reason: Anergia refers specifically to a profound lack of physical energy or chronic lethargy often seen in depressive disorders. While it frequently co-occurs with the patient's symptoms, the patient's statement focuses on the loss of pleasure and emotional "happiness" rather than a deficit in physical vigor or activity levels.

Choice B reason: Anhedonia is the clinical term for the inability to experience pleasure from activities that were previously found enjoyable, such as holidays or hobbies. It is a core symptom of major depressive disorder and reflects a dysfunction in the brain's reward system, accurately describing the patient's reported lack of joy.

Choice C reason: Euphoria is characterized by an exaggerated feeling of well-being, elation, or intense happiness, often observed during manic or hypomanic episodes. This is the direct clinical opposite of what the patient is describing, as they are reporting a total absence of positive affect and a sense of emotional numbness.

Choice D reason: Dysthymia, now referred to as Persistent Depressive Disorder, is a chronic, low-grade depression lasting at least 2 years. While the patient mentions feeling this way for "a long while," the specific symptom described—the loss of the ability to feel pleasure—is a discrete psychopathological finding known as anhedonia.

Reasoning:

Choice A reason: The patient’s statement indicates that they have reached the goals of crisis intervention: achieving balance and a sense of strength. By suggesting more sessions to explore "why" (which is long-term therapy, not crisis intervention), the nurse is likely experiencing countertransference and struggling with the planned termination of the relationship.

Choice B reason: Transference occurs when a patient displaces feelings for a significant person from their past onto the nurse. There is no evidence in the patient’s statement of inappropriate emotional displacement; the patient is expressing healthy gratitude and a successful resolution of the crisis, which is the goal of treatment.

Choice C reason: The patient's statement actually suggests the opposite of a need for continuing support. Phrases like "emerged a stronger person" and "back in balance" signal that the patient has regained their pre-crisis level of functioning and is ready to move forward independently, without further clinical intervention.

Choice D reason: The nurse's response does not demonstrate empathy. Instead, it pathologizes the patient's past reactions and attempts to extend the relationship unnecessarily. Empathy would involve validating the patient’s sense of growth and confirming that they are indeed ready to manage their life without further sessions.
