Nursing is a health-care profession dedicated to assisting individuals, families, and groups in achieving, maintaining, or regaining optimal well-being and personal satisfaction. Nurses' approach to managing understanding, planning, and scope of practice may set them apart from other health care workers. Nurse education has changed over the past decade to include more cutting-edge and focused certificates, as well as a growing number of traditional controls and provider parts. Nurses, in collaboration with doctors, advisers, patients, patient's families, and other colleagues, create a plan of care that focuses on treating illness and improving quality of life. Nursing science is now a part of the research and development of new techniques to enhance health outcomes. Nursing science retains a key human element in the balance of care in a world with rising technical diagnostics and almost endless data sets.
