Health education is an integral part of nursing activities. Health education is not the extra work of nurses, but one of the contents of nursing, and it is also one of the very important contents. Many nursing goals are achieved through health education, such as improving patients' adaptability, reducing anxiety, restoring limb function, establishing self-behavior ability and reducing complications. In addition, some health education contents are designed according to the needs of nursing work [2]. Because the content of health education needs to be targeted, nurses need to find out nursing problems from the collected nursing materials and determine the content of health education according to these problems, so that patients can obtain high-quality care through health education and improve their satisfaction. For example, in the treatment of a cancer patient undergoing chemotherapy, besides preventing infection, maintaining the balance of body fluids and electrolytes, and providing proper nutrition, we should also pay attention to maintaining the patient's emotional stability and good self-image, which is particularly important for female patients. Therefore, in the health education before chemotherapy, in addition to telling patients what may happen after chemotherapy, such as hair loss is the most common symptom, even eyelashes and eyebrows will fall off, nurses will take some measures, such as using ice caps to reduce hair loss, and should also teach patients how to wear wigs and how to cover up some physical defects with scarves, hats and eyebrows. Therefore, health education and nursing work are inseparable. The combination of health education and clinical nursing has long been an important mode of modern nursing. On 1998, the First Affiliated Hospital of Guangzhou Sun Yat-sen University of Medical Sciences took the lead in setting up the "Health Education Service Department" in China, which not only provided powerful help and support for clinical holistic nursing, but also improved nurses' health education skills, improved the social image of the hospital and embodied the hospital's modern service consciousness [3].
1.2 The concepts of health education and health education are different. From health education to health education, the working mode changes. Health education only uses general propaganda techniques and means to spread health knowledge and related disease knowledge. Our government has always attached importance to the health level of the whole people, set up various activity days, held large-scale popular science activities, publicized and popularized health knowledge, and raised the health awareness of the whole people. In these activities, nurses only assume the roles of participants and communicators. Therefore, nurses are not required to have theoretical knowledge and operational skills. However, nursing health education is not. It is a multi-disciplinary specialty, which requires nurses not only to have basic medical knowledge, but also to master the knowledge of psychology, society, behavior and education, so as to make a comprehensive evaluation of patients' situation and communicate effectively. Especially in health education activities, according to health education procedures, they have to assume various roles such as disseminators, planners and evaluators. They should give health education to patients. Because the ultimate goal of health education is to enable patients to establish healthy behaviors, the operating system should also be changed from simple knowledge instillation to a scientific working system that operates according to educational procedures.
