We will first define the term "Research" before explaining the term Nursing Research. Research is a scientific process. It is defined as a systematic search for answers to questions about facts and relationships between facts. You may find that some research discovers new facts whereas some research establishes relationships between two or more facts.
The research is called scientific because the results are verifiable that is, if you do it again under the same conditions, you will get the similar results. The systematic method has an order and follows an acceptable procedure for doing the research.
Nursing research refers to the use of systematic, controlled, empirical, and critical investigation in attempting to discover or confirm facts that relates to specific problem or question about the practice of nursing.
