Comparison and Analysis Across Theories EssayThe purpose of the nurse theories is to provide an interrelating framework think on the treat practice. The defined nursing theories promote better patient c be, emend the status of nursing profession, and improve the communication between the nurses, and provide guidance to the researches and education (Keefe, 2011). Not all nursing theories assume the same meanings however, they play the important role of explaining the key judgments and principles of nursing practice in understanding way. Dorothy Orems Self-Cargon Deficit Theory and Sister Callista Roys adjustment example argon considered as grand nursing theories. The grand nursing theories are a conceptual model, which identifies the focal point of nursing inquiry and operate the development of mid-range theories that will become useful to nurses and also to other health professionals. fit in to Walker and Avant (2011), these theories contributed in conceptually sortin g the nursing from the practice of medicine by demonstrating the presence of distinct nursing perspectives. In this essay, Orems Health Care Deficit Theory and Sister Callista Roys Adaptation Model are compared and analyzed for their importance in nursing. Orems Self-Care Deficit TheoryOrems Self-Care Deficit Theory is matchless of three grand theories written by Dorothea E. Orem. According to Orem, nursing becomes necessary when an individual tail end no longer do by for him or herself. Nursing provides care through acting, guiding, relievering, teaching, and surroundal manipulation promoting personal development. Orem unquestionable this theory from her experience and personal connection with the Vincentian-Louisiana nursing tradition of the Daughters of Charity (Libster, 2008.)Roys Adaptation ModelRoys Adaptation Model provides the framework for nurses by viewing the adaptability of patients to internal and external stimuli in their environments (Alligood Tomey, 2006.) Repo nses to these stimuli can be either adaptive, which promote the goals of human survival, growth, reproduction and mastery, or non-adaptive (Roys Adaptation, 2011.)MetaparadigmThe metaparadigm for nursing is the concepts that define the nursing practice. Since 1970s, person, nursing, health, and environment are considered as the core concepts of nursing theories by many nursing theorists.PersonAccording to Orem, a person is made of a physical, psychological, and social character with variable degrees of self-care ability (Dorothea Orems Self, 2011.) Roy views a person as an adaptive system that responds to internal and external stimuli in their environments (Alligood Tomey, 2006.)NursingOrem and Roy have the different attitude toward the concept of nursing. Orem sees nursing as an intervention to meet the daily needs for self-care and medical-care patients need (Dorothea Orems Self, 2011.) Roy believes nursing as a key player to help patients to develop coping mechanism and positive outcome from the constant stimuli exposure. Roys goal is for the patient to achieve adaptation leading to optimum health, well-being, quality of life, death with dignity, and finding in life by participating in their own care (Roy Andrews, 1999.)HealthOrem defines health as physical, psychogenic and social well being (Dorothea Orems Self, 2011.) Roy views health as a method used by patients to vex their utmost possible health regardless of the presence or absence of disease.EnvironmentOrem and Roy both res publica the individual exists in an environment. Orem sees the environment in two dimensions, the physical, chemical, biologic features and socioeconomic features, which influence the self-care requirements of the individual (Dorothea Orems Self, 2011.) According to Roy, the environment consists of stimuli including conditions, circumstances, and influences surrounding an individual, whether focal, contextual, or residual.In PracticeOrems Self-Care Deficit Theory and Roys Ada ptation Model can be applied to groups or individuals, and used at any nursing settings. However, Orems Self-Care Deficit Theory is more recommended for the acute-care setting, where a patient receives active but short-term treatment for a severe injury or episode of illness. Orem focuses on finding the self-care deficit of the patient and providing the necessary care to promote his or her well-being. Whereas, Roy is concerned with the different stimuli that forces adaptation in order to achieve optimal health. Roys Adaptation Model views the person as an adaptive system which includes the four adaptive modes. These adaptive modes are physiological-physical mode, self-concept-group identity mode, role function mode, and interdependence mode. Although first two modes can be identified immediately, the estimation of role function mode and interdependence mode is time consuming. Therefore, Roys Adaptation Model is not suitable for acute-care setting.ConclusionHaving defined nursing th eories promotes better patient care, improve the status of nursing profession, and improve the communication between the nurses. In addition to guiding the nurses to provide the best care to the patients, nursing theories are used to promote and guide baccalaureate programs, administration and nursing research. Many organizations now exist to support the advancement of nursing profession. Sigma Theta Tau International, the Honor Society of Nursing, is created to support the learning, knowledge and professional development of nurses committed to qualification a difference in health worldwide (STTI organizational, 2011.) International Orem Society promote the advancement of nursing science and provide scholarship in the area of Orems Theory of Self-Care Deficit Nursing to lead to just advancement of knowledge for the discipline of nursing (International Orem, 2011.) The Roy Adaptation Association (RAA) is a society of nursing scholars who deficiency to advance nursing practice by developing basic and clinical nursing knowledge found on the Roy Adaptation Model (Roy Adaptation, 2011.) These organizations along with progression of the nursing theories will promote the advancement of nursing science and enhance the nursing profession.ReferencesAlligood, M., Tomey, A. (2006).
