Nursing process is defined as an organized systematic method of giving individualized nursing care that focuses on identifying and treating unique responses. It provides a frame work with which needs of the patient/family/community can be met. It begins when the patient needs assistance with health care of individuals or groups to actual or potential alteration in health. The North American Nursing Diagnosis Association (NANDA), has developed and classified nursing diagnosis, gives a clear distinction between nursing diagnosis and medical diagnosis. A good nursing care involves proper analysis and a good fluent language helps the patients to discuss freely with the nurses. The basic five steps in nursing process include assessment, nursing diagnosis, planning, implementation, and expected outcome. Diagnostic examinations and organizing the information is by clustering data in a concise way. These five steps are explained in detail in the chapter.
