Henderson stated that maintaining a supportive environment conducive for health is one of the elements of her 14 activities for client assistance.
Henderson’s theory supports the tasks of the private and the public health sector or agencies in keeping the people healthy. She believes that society wants and expects the nurse’s service of acting for individuals who are unable to function independently.
Good health is an individualized concept, impacted by age, culture, abilities and emotions. Nurse stress health promotion and cure disease. Health was taken to mean balance in all realms of human life. It is equated with the independence or ability to perform activities without any aid in the 14 components or basic human needs.
Nurses, on the other hand, are key persons in promoting health, prevention of illness and being able to cure. According to Henderson, good health is a challenge because it is affected by numerous factors such as age, cultural background, emotional balance, and others.
Henderson states that individuals have basic needs that are component of health and require assistance to achieve health and independence or a peaceful death. According to her, an individual achieves wholeness by maintaining physiological and emotional balance.
Virginia Henderson wrote her definition of nursing before the development of theoretical nursing. She defined nursing as “the unique function of the nurse is to assist the individual, sick or well, in the performance of those activities contributing to health or its recovery that he would perform unaided if he had the necessary strength, will or knowledge. And to do this in such a way as to help him gain independence as rapidly as possible.” The nurse’s goal is to make the patient complete, whole, or independent. In turn, the nurse collaborates with the physician’s therapeutic plan.
Nurses temporarily assist an individual who lacks the necessary strength, will, and knowledge to satisfy one or more of the 14 basic needs. She states: “The nurse is temporarily the consciousness of the unconscious, the love life for the suicidal, the leg of the amputee, the eyes of the newly blind, a means of locomotion for the infant, knowledge, and confidence of the young mother, the mouthpiece for those too weak or withdrawn to speak”
Nursing, Health, Environment and the Individual are central to this theory. They interact in every step of meeting a patient's needs and should be considered as inter-related.The following are the major concepts (nursing metaparadigm) and definitions of the Need Theory of Virginia Henderson.
