A low range level theory is an observation and interpretations that emerge from hands-on work. A middle level theory is a hypothesis that is link with observations. As for high level theory, is seeks to answers of large questions such as “why”. In the past and now, the nursing profession has relied on theories from other disciplines. The theories are different in terms of their applications grounds. The high range theory are above the minor range while the middle range theories are positioned between the minor range. For example, middle range theories focus on specific concepts such as pain or stress. The second middle range theory is self efficacy it is denied as a system of self monitoring in which the nurse monitors self abilities and works for success in providing effective care to the patients. The characteristics of middle range theories are its concept and propositions that are specific to nursing, it is readily operationalized, it can be applied to other propositions from casual to associative, and it should be relevant for nurses and carry out outcomes that are important for patients.However, low middle range theories are more defined and specific. For example, acute pain management and intervention for post surgical pain. A well example in which research study is applied to middle range theory is the care for hospice patients. Hospice care is the modern nursing practice that express the total patient’s care involving care of the body, mind, and spirit. This approach to the treatment of disease is that it all begins with a disorder in the body causing bodily  harm which leads to impairment of being compliant to health or functioning of the body. Nurses must consider that the physical, economic, social, emotional, and spiritual needs of the patient is the response to illness.  ??????????????????????????????????
