The term informatics is used to describe all aspects of computers and information systems; it is interdisciplinary, combining the aspects of computer science, cognitive science, and information science. The World Wide Web is a synonym for the internet. A PDA, or personal digital assistant, is a mobile device which functions as a personal information manager and has the ability to connect to the internet. Nurses are information processors; gathering data, synthesizing information, organizing and structuring a plan of care from the processed information. Informatics does not refer to the many ways that nurses use data to complete patient care.
Answer to Question 2
Correct Answer: 4
Lewin's three basic steps or stages are unfreezing, moving, and refreezing. Lewin based his theory on the concept that within the physical sciences change is a result of forces within a field or environment (driving and restraining forces). It is the job of the change agent to reduce the restraining forces or increase the driving forces. Instruct, manage, and reward are elements that a change agent may use to reach desired behaviors, these elements are not in Lewin's theory of change. Chaos, change, and control are not elements of Lewin's theory. Trust, autonomy, and initiative are skills needed by change agents but are not elements of Lewin's theory.
