Theoretical Basis of Practice
The understanding of nursing theory provides the advanced practice nurse with a scientific basis and allows them to conceptualize nursing care within the context of a comprehensive framework. Philosophy, theories, and empirical generalizations provide roots for each process of reasoning (Smith & Liehr, 2014). As each process of reasoning is developed and underpinned by theories, nursing knowledge will continue to improve (Fawcett, 1984). Utilization of a systematic approach within a professional practice that includes focusing on the patient and the theoretical works provide perspectives of the patient (Tomey & Alligood, 2006). The purpose of this paper is to investigate the meta-paradigm of nursing, grand …show more content…
TBIs constitute for a leading cause of death and disability in the United States, with 7.7 million people living with TBI-related disabilities (Dunkley & McLeod, 2017). The treatment of TBIs is controversial related to the use of therapeutic hypothermia. Therapeutic hypothermia is considered the generated cooling of patients to 32-35 degrees Celsius, to alleviate the secondary brain injuries that occur and improve the neurological outcomes of the patient (Dunkley & McLeod, 2017). Four benefits are noted with therapeutic hypothermia. The chief advantage is a reduction in the metabolic rate of the brain. Decreasing the metabolic rate decreases the oxygen and glucose consumption of the brain (Cook, 2017). Other benefits of therapeutic hypothermia include the ability of the brain to tolerate lower oxygen thresholds, the oxyhemoglobin threshold is shifted to the left providing decreased carbon dioxide consumption, and the reduction of cerebral edema (Cook, …show more content…
The subject of nursing is surrounded by the four components of the nursing meta-paradigm: person, environment, health, and nursing. The subject is better defined by evaluating through the lens of the meta-paradigm within the discipline (Fawcett, 2005). The subject of TBI management encompasses the family and the patient in the critical life event that consists of multifaceted variables that alter the patient’s homeostasis more than merely physiologically. The phenomenon of interest explained draws upon the four concepts presented by the meta-paradigm and the three recurring

Nursing Theory: Compare/Contrast Two Theories

...Theory: Compare/contrast two theoriesIntroduction Theory has so far remained a strategic tool in advanced nursing practice. Firstly, nursing utilizes every feature of management science. Fortunately, the knowledge base of each and every management science takes theory into account. Theory includes methods, principles, and concepts. The principles are usually related, and can be observed and validated or verified when translated into the practice of management. Likewise, concepts are general notions, thoughts, and ideas that tend to form a basis of discussion or action. Therefore, theoretical principles guide clinical nurses to various fundamental nursing concepts and provide productive line of action in a given situation. As a result, nurses should note that taking a hermeneutic or phenomenological approach (strict natural science approach) to nursing is not only naive but also misleading in real-life-settings. Alligood and Tomey, on the other hand, argues that prescriptive theories are often used as fundamental practice guidelines, which play a pivotal role in providing a wide range of practice situations in the nursing and nursing sector (2002). Apart from that, nursing can only become a real profession when it has both a theoretical and a scientific base. This follows the fact that nurses deal mainly with human behavior, thus, nursing is indeed a practice profession. Briefly speaking, nurse managers can achieve effective management by combining the theory of nursing with...

...1365-2648.2009.05157.x Abstract Title. The use of theory in qualitative approaches to research: application in end-of-life studies. Aim. This paper is a report of an analysis of the use of theory in qualitative approaches to research as exemplified in qualitative end-of-life studies. Background. Nurses researchers turn to theory to conceptualize research problems and guide investigations. However, researchers using qualitative approaches do not consistently articulate how theory has been applied, and no clear consensus exists regarding the appropriate application of theory in qualitative studies. A review of qualitative, end-of-life studies is used to illustrate application of theory to study design and findings. Data sources. A review of theoretical literature was carried out, focusing on definitions and use of theory in qualitative end-of-life studies published in English between 1990 and 2008. Discussion. The term ‘theory’ continues to be used in a variety of ways by theorists and researchers. Within the reviewed end-of-life studies, the use of theory included theory creation or provision of a comparative framework for data analysis and interpretation. Implications for nursing. Nurses who...

Theoretical Perspective Provide a minimum 500-word sociological analysis of the issue you have chosen. Use your textbook as well as other sociological sources (e.g., textbooks, journal articles) in this section. You will need to select one sociological theory which is relevant to your chosen issue, state the main ideas of this theory, and explain how effective the theory is in helping to understand the chosen issue. Conclusion Provide a minimum 200-word summary which explains how health sociology theory provides a different way of making sense of the organisation of health care. ISSUE DESCRIPTION The rise of nurse practitioners concerns the extension of some aspects of nursing practise to incorporate tasks once only performed by doctors. The issue here is whether the rise of the nurse practitioner role improves the agency and professional status of nursing, and the extent to which it is resisted by doctors as a challenge to their clinical autonomy. Nurse practitioners fall under the category of advanced practise nurses. The Australian nursing and midwifery council (ANMC) has proposed the following broad definition of advanced practice nursing: “Advanced practice nursing defines a level of nursing practice that utilises extended and expanded skills,experience and knowledge in assessment, diagnosis, planning, implementation and evaluation...

This article is conceptual based which is largely based on presenting the reasoning of different theories. Employee Commitment and Motivation: A Conceptual Analysis and Integrative Model uses various theories about motivation and commitment. 3. Brief Summary This article tried to assert commitment is one part of motivation and, by integrating theories of commitment and motivation, For example, because commitment often involves psychological attachment to social foci, incorporating commitment as an independent aspect of motivation should allow enhanced understanding of behaviors that have broader social implications. The article begin its attempt at integration by providing a broad overview of theory and research pertaining to workplace motivation and commitment. Both are complex concepts, and therefore a comprehensive analysis is beyond the scope of the article. Specifically, the article incorporated theory and research on work motivation into a general model of the motivation process. Acknowledging...

Imprortance of Theory: Jean Watson’s Caring Theory

...reorganization at the administration level. Things are changing, practice and healthcare policy continue to transform at a rapid rate. Nursing theory has worked to provide stability and rationality to the ever changing field of nursing. The profession of nursing, just like any other profession, must work to prove the legitimacy of its practice which is accomplished through the confines of theory (McCrae, 2012). According to Alligood (2014), nursing theory not only fosters the development of nursing education and literature but also assists in practice advancement. This is important for laying a foundation and progressing in the field of nursing and helps to provide the basic knowledge for nursing care that involves “caring”. With all the change and uncertainty in healthcare, human caring has the potential to become a lost cause (Cara, 2003). Caring should be a central theme in nursing and the foundation of all nursing care (Watson, 2009). The goal of this paper is to explore and summarize the central ideas of Jean Watson’s Theory of Caring and to apply her theory to current practice and show its relevance to nursing education. Importance of Watson’s Theory of Caring Nursing care is made up of many factors, to include, knowledge, influence, experience, ethics and much more. Considering all that nursing is and does, a particular theory can paint a grand picture of what nursing care should be. Holistic nursing practice often generates from nursing knowledge, theories, expertise...

Importance of Theory

...2016 Importance of Theory Paper The nursing philosophy is a group of concepts that help provide a method for treating and caring for patients. Nursing theory also can be an instrument of effort that emphasizes scientific facts, it will also show the trends of views of the wellbeing -disease course of action and the practice of healing care. The different nursing theories that have been planned contain ways in which patients should be treated. Principles of nursing theories require the nurse to assess the patient and understanding how the patient will respond to the cost of his or her illness. Theory is defined as "a belief, policy, or procedure proposed or followed as the basis of action". Nursing theory is "an organized framework of concepts and purposes designed to guide the practice of nursing (Nursing Theory, 2015)". Nursing philosophy helps guide nurses in their everyday nursing routine to help give their patients the best quality care. The three types of nursing theories in nursing are, nursing practice, grand theory, and middle range theory. Research and Studies results show, that nurses who incorporate nursing theory in their practice, give the best care to their patients. I will explain how Orem’s nursing theory on self-care helps patients achieve the goal of taking care of themselves with the help and guidance of the nurse. As patients come in the hospital or their primary care doctor’s office with an illness that inhibits them to take care of themselves...

Mean and Standard Deviation

...of urinary lead; n is the number of these values; and σ , the Greek capital sigma (our "S") denotes "sum of". A major disadvantage of the mean is that it is sensitive to outlying points. For example, replacing 2.2 by 22 in Table 1.1 increases the mean to 2.82 , whereas the median will be unchanged. As well as measures of location we need measures of how variable the data are. We met two of these measures, the range and interquartile range, in Chapter 1. The range is an important measurement, for figures at the top and bottom of it denote the findings furthest removed from the generality. However, they do not give much indication of the spread of observations about the mean. This is where the standard deviation (SD) comes in. The theoretical basis of the standard deviation is complex and need not trouble the ordinary user. We will discuss sampling and populations in Chapter 3. A practical point to note here is that, when the population from which the data arise have a distribution that is approximately "Normal" (or Gaussian), then the...
