A nurse is caring for a client who states, "I am under a great deal of stress at work, but I am able to forget my work and concentrate on my family when I get home at night." The nurse should identify that the client is demonstrating which of the following defense mechanisms?

Choice A reason : Rationalization is a defense mechanism where an individual justifies behaviors or feelings with plausible but inaccurate explanations to avoid confronting the true underlying motives or facts. In this scenario, the client is rationalizing their failure to take medication by blaming their partner's forgetfulness, rather than accepting personal responsibility for their health management.

Choice B reason : Projection involves attributing one's own unacceptable thoughts, feelings, or motives to another person. If the client had accused their partner of being irresponsible with medication as a reflection of their own behavior, it would be an example of projection. However, in this case, the client is not projecting their own forgetfulness onto their partner but rather shifting the blame.

Choice C reason : Repression is an unconscious mechanism employed by the ego to keep disturbing or threatening thoughts from becoming conscious. It involves pushing uncomfortable thoughts or memories into the unconscious mind. The client's statement does not suggest they are unconsciously forgetting to take their medication; instead, they are consciously aware of their action and providing a justification for it.

Choice D reason : Regression is a return to earlier stages of development and abandoned forms of gratification belonging to them, prompted by dangers or conflicts arising at one of the later stages. A client demonstrating regression might exhibit childlike behaviors when faced with stress. The client's statement does not indicate a regression to more infantile behaviors or coping mechanisms.

Choice A reason : Decreased blood pressure is not a typical response to the fight-or-flight reaction. During this response, blood pressure usually increases due to the release of stress hormones like adrenaline, which cause the heart to beat faster and harder.

Choice B reason : Dilated pupils are a common manifestation of the fight-or-flight response. This physiological change allows more light into the eyes, which can improve vision and help an individual to better assess the situation and respond to potential threats.

Choice C reason : Bronchial airway constriction is not associated with the fight-or-flight response. In fact, the bronchial airways typically dilate to increase airflow and oxygen intake to prepare the body for action.

Choice D reason : Hypoglycemia, or low blood sugar, is not a direct result of the fight-or-flight response. The body actually mobilizes glucose stores, leading to elevated blood sugar levels, to provide energy for muscles during a stress response.
