Paradigm is the sum of a person's beliefs, as well as understanding of any facts and experiences he or she encounters. In nursing science, the paradigm addresses the most abstract set of central concepts that include: the person, the environment, health, and the nurse's perception of the patient. For the nurse, the paradigm creates a nursing framework that “provides a comprehensive perspective for nursing practice” (Alligood, 2014, p.45). Nursing theories develop from this framework and these theories are the guiding frameworks of nursing practice, postulating focus for nursing care delivery, critical thinking and decision making. These theories may develop from “a philosophy, a nursing model, a more abstract nursing theory, or a framework from another discipline” (Alligood, 2014, p.43).

The parents were very anxious, very tearful and did not know how to help their child. The doctor ordered a computed tomography (CT) scan, and the CT revealed a huge mass in the frontal area of ​​the brain suspected of malignancy. The neurosurgeon explained to them that she needed immediate surgical removal of the tumor and that the girl would have to stay in the hospital for quite a long time for further treatment. The doctor couldn't give them much hope as to whether or not the girl's cancer would be cured and whether she would return to normal.
