A nurse is teaching a class about palliative care. Which of the following statements should the nurse include?

Choice A reason: Physiological stressors, like infections or injuries, directly disrupt homeostasis (e.g., increasing cortisol via hypothalamic-pituitary-adrenal axis activation). Stress without a specified physical cause (e.g., pain, hypoxia) is more likely psychological, as the client’s symptoms suggest emotional or cognitive distress, not a direct physiological insult.

Choice B reason: Psychological stressors, such as anxiety or emotional distress, activate the amygdala and hypothalamic-pituitary-adrenal axis, increasing cortisol and catecholamines, leading to stress symptoms like elevated heart rate or impaired concentration. Without physical injury or illness specified, the client’s stress aligns with psychological causes, affecting mental health.

Choice C reason: Environmental stressors (e.g., noise, crowding) trigger stress via sensory overload, engaging the sympathetic nervous system. Without specific environmental cues in the scenario, the client’s stress is more likely psychological, as emotional or cognitive factors are common in unspecified stress presentations, not external environmental triggers.

Choice D reason: Occupational stressors, like work pressure, activate stress responses via cortisol and sympathetic activation, affecting cardiovascular and mental health. Without work-related context, the client’s stress is more likely psychological, stemming from internal emotional or cognitive factors, not specific job-related demands or workplace conditions.

Choice A reason: Anemia results from factors like iron deficiency or chronic disease, not directly from prolonged stress. Stress may elevate cortisol, affecting hematopoiesis indirectly, but anemia is not a primary manifestation. Chronic stress primarily impacts neuroendocrine and immune systems, not red blood cell production or hemoglobin levels.

Choice B reason: Prolonged stress typically increases blood pressure via sympathetic activation, releasing catecholamines (e.g., epinephrine), which cause vasoconstriction and elevated heart rate. Decreased blood pressure is not a common stress response, as the hypothalamic-pituitary-adrenal axis drives hypertension, not hypotension, in chronic stress scenarios.

Choice C reason: Prolonged stress elevates cortisol and catecholamines, suppressing immune function by inhibiting T-cell proliferation and cytokine production. This reduces the body’s ability to fight infections, increasing susceptibility to illness. Chronic activation of the hypothalamic-pituitary-adrenal axis downregulates immune responses, a well-documented effect of sustained stress.

Choice D reason: Hypoglycemia is not a typical manifestation of prolonged stress. Stress hormones (cortisol, glucagon) increase blood glucose by promoting glycogenolysis and gluconeogenesis to provide energy. While acute stress may cause transient glucose fluctuations, chronic stress typically leads to hyperglycemia, not low blood sugar, in most individuals.
