A nurse is teaching a class about sources of stress. Which of the following is an example of a physiological stressor?

Choice A reason: Change in marital status is a psychological stressor, activating the hypothalamic-pituitary-adrenal axis, increasing cortisol, and causing emotional distress. It affects mental health through social and emotional pathways but does not directly disrupt physiological homeostasis, unlike physical injuries that trigger systemic stress responses. Choice B reason: A burn injury is a physiological stressor, causing tissue damage, pain, and systemic inflammation. It activates the sympathetic nervous system and releases stress hormones (e.g., catecholamines, cortisol), increasing metabolic demand, heart rate, and immune response to repair tissue and combat potential infections, disrupting bodily homeostasis. Choice C reason: Academic pressure is a psychological stressor, engaging cognitive and emotional pathways, elevating cortisol via the hypothalamic-pituitary-adrenal axis. It impacts mental health but lacks direct physical disruption to bodily systems, unlike physiological stressors that cause immediate tissue or metabolic changes, such as infections or injuries. Choice D reason: Financial difficulties are psychological stressors, triggering anxiety and cortisol release through emotional distress. They affect mental health but do not directly cause physiological disruption like tissue damage or metabolic imbalance, which are characteristic of physiological stressors impacting the body’s physical homeostasis and organ function.
