Florence Nightingale is attributed with establishing the modern practice of nursing. She also contributed to the field with nursing theories still used today. One of her nursing theories is the Environmental Theory, which incorporates the patients’ surrounding environment in his or her nursing care plan. In this theory, the role of the nurse is to use the patient’s environment to help him or her recover and get back to the usual environment. The reason the patient’s environment is important is because it can affect his or her health in a positive or negative way. Some environmental factors affecting health according to Nightingale’s theory are fresh air, pure water, sufficient food and appropriate nutrition, efficient drainage, cleanliness, and light or direct sunlight. If any of these factors is lacking, it can delay the patient’s recovery. Nightingale also emphasized providing a quiet, warm environment for patients to recover in. The theory also calls for nurses to assess a patient’s dietary needs, document food intake times, and evaluate how the patient’s diet affects his or her health and recovery. Determining a patient’s environment for recovery based on his or her condition or disease is still practiced today, such as in patients suffering from tetanus, who need minimal noise to keep them calm and prevent seizures.
