Arguably, two of the most fundamental aspects of the nursing profession include theory and practice research. The relationship between the three aspects can be described as cyclical and reciprocal. It is through clinical practice that knowledge and research questions become available for theory. Research can only guide practice and create knowledge by means of theory development. It is, therefore, safe to say that theory not only guides research but also improves practice. For nursing to complete their caregiving roles, they need a wide variety of aspects, including skills, knowledge, art, and caring skills. It is only through research findings that nurses can have the much-needed knowledge to make clinical decisions.
In an ideal situation, all the decisions directed towards the care of the patients should be backed with evidence. The research findings enable the nurses to come up with protocols which are in turn used to guide the daily nursing practice. In any area of study, science is built on two fundamental pillars that include research and theory. The role of research is to create knowledge through not only the generation but also the testing of theories. In the nursing profession, a theory has a critical role in influencing and improving patient care.

Several types of nursing theories exist. They include metatheory, grand theory, practice theory, and range theory. Practice theories have influenced the way nurses handle their patients. They are based on a number of essential concepts and tenets that guide nurses on the best method to work, which will significantly improve patient outcome. Grand theories focus on understanding the world in which people live and how they interact with people. Meta-theories tend to combine two or more theories that in the end, impact the role of nurses. Range theories on their part seek to integrate research from empirical evidence.
