The nursing purpose is to establish and actively participate in a holistic healing approach, focusing on the individual and not just the disease. Critical thinking and evidence-based practice mobilize the nursing process and provide a foreground for the medical profession. Nursing is a selfless endeavor that exemplifies the sacrifice of the nurse to attend to a stranger's needs before her own. A nurse's obligation is not to treat a sick client, nor their families or communities, but to help strengthen external influences that compromise health. The nurse is there to fulfill a desire for health by alleviating external stressors, educating individuals, and henceforth creating balance within the environment, which in return allows individuals to establish a sense of homeostasis. A nurse must be impartial, responsible and always honest with the patient. For example, Hegge emphasizes the importance of honesty in her statement: “She [Florence Nightingale] warned against giving patients false hope when recovery was not possible” (2013, pp. 214). The reason the nurse must overcome her own personal emotions is because she is required to tell the patient what he needs to hear, not what he wants to hear.
