Nursing research advances knowledge about health and health promotion across the lifespan, as well as the care of people with health problems and disabilities, and nursing interventions to improve people's ability to respond effectively to present or potential health issues. Nursing research focuses on these areas in addition to biological research, which is largely concerned with disease causes and cures. Nurses perform a variety of studies in order to develop clinical interventions to help persons who require nursing care. The complexities of nursing research, as well as its extensive reach, frequently necessitate scientific support from a variety of disciplines. As a result, nursing research crosses traditional research boundaries and employs methods from a variety of fields. Nurse education emphasizes the use of research-based data to rationalize nursing interventions.
