Chapter 7: Stress Management in Acute Care

Stress is conceptualized as an individual's inability to cope with perceived demands or threats to well-being, manifesting as either beneficial eustress or harmful distress depending on personal perception and contextual factors. The physiological stress response involves complex interactions between the nervous, endocrine, and immune systems, particularly through activation of the sympathetic nervous system and hypothalamic-pituitary-adrenal axis, resulting in catecholamine and cortisol release that produces the characteristic fight-or-flight response. While acute stress responses are adaptive, chronic stress exposure leads to immunosuppression, increased infection susceptibility, and development of stress-related disorders including cardiovascular disease, diabetes, anxiety, and depression. The chapter emphasizes psychoneuroimmunology principles, examining how prolonged stress affects natural killer cell function, cytokine production, and cellular aging through telomere shortening. Coping mechanisms are differentiated into problem-focused strategies that address stressor sources directly and emotion-focused approaches that manage emotional responses to stressors. Multiple relaxation techniques are presented as therapeutic interventions, including diaphragmatic breathing, progressive muscle relaxation, guided imagery, meditation, biofeedback, and complementary therapies such as music therapy, aromatherapy, and pet therapy. These interventions activate the parasympathetic nervous system, counteracting stress responses by reducing heart rate, blood pressure, and muscle tension while promoting healing and recovery. The nursing role encompasses comprehensive stress assessment, implementation of individualized stress management interventions, patient education regarding coping strategies, and modeling wellness behaviors to enhance both patient outcomes and professional resilience in acute care environments.
