Nursing Theory And Philosophy Nursing Essay

Nursing Theory And Philosophy Nursing Essay Prior to the development of nursing theories, nursing practice was viewed as a series of tasks that required little to no rationale. The evolution of nursing theories and philosophies has facilitated the progression of nursing as a vocation to nursing as an academic discipline and profession. Nursing theory promotes autonomy when used as a guide for critical thinking and decision making. Ultimately nursing theory and philosophy has increased knowledge development and enriched the quality of nursing practice (McEwen Wills, 2011). Nursing philosophy and theory are two interchangeable terms. The philosophy a nurse has on nursing will determine the theory and model he or she uses. Nursing philosophy explains what nursing is and gives insight to why nurses practice the way they do. Nursing theory describes how nurses and patients are able to produce healing and good health, by using models to explain how beliefs and aspects of health are related. Theory is used to explain and analyze what nurses do as well as facilitate communication between nurses and guide research and education. Nursing theory encompasses the foundations of nursing practice past and present and provides direction for how nursing should develop in the future (Alligood Tomey, 2002). Nursing theory is a broad term, according to Marilyn Parker in Nursing Theories and Nursing Practice, which portrays and clarifies the phenomena of interest. Nursing theory provides understanding for the advanced practice nurse to use in actual practice and evidence based research. Nursing theory has many purposes, which imitate the multiples specialties in professional nursing. Ultimately the goal is to promote the delivery of the best quality of care. The functions of nursing theory are to guide thinking, define the place of nursing in health and illness care, and to provide organization for the development of nursing education (Parker, 2006). Nursing theory provides a format for professional nursing to practice and make decisions. There are three major types of nursing theory: grand theory, middle range theory, and nursing practice theory. Each of these theories helps the nurse to provide more proficient patient care (McEwen Willis, 2011). The purpose of nursing theories is guide encourage and increase autonomy of nursing. Nursing theory improves communication with other health professionals and develops ideas and words by building a common nursing terminology. Theories have become necessary for effective decision making and implementation because they provide a basis for collecting reliable and valid data. Nursing theory is key in the practice of nurses and advanced practice nurses because it serves as a guide to assessment, intervention, and evaluation of care. Theory provides a measurable way to evaluate the quality of nursing care (Colley, 2003). According to Meleis, there are many beneficial uses of nursing theory. Nursing theory provides a basis for research and a frame of reference for patient assessment, diagnosis and intervention. It makes nursing practice more competent and valuable. Nursing theory provides a common platform for communication between the advanced practice nurse and other disciplines involved in a patients care. It supports the professional autonomy, responsibility, and liability of the advanced practice nurse (Meleis, 2011). Benefits of theory based practice are structure and organization, a systematic, purposeful approach, focus, coordinated and less fragmented care, and identifiable and traceable goals and outcomes. While there are many benefits of nursing theory, there are some barriers to developing and applying nursing theory. Nurses are considered doers, not thinkers. A lot of people choose to pursue the nursing profession to be advocates and to help and assist people, not to think about philosophical or ethical issues. Financial stress and a focus on career advancement within the nursing profession is proven to be a major barrier to philosophical thinking about nursing and seeking out education and training. The biggest obstacle in trying to effectively apply a nursing theory, is trying to use the wrong type of theory, or model, in a specific nursing situation. One type of theory cannot be applied every patient stipulation. Also, many nurses do not have an sufficient understanding of the types of nursing theories to use them effectively (Meleis, 2011). Three popular nursing theorists are Florence Nightingale, Jean Watson, and Dorothea Orem. Florence Nightingale published, Notes on Nursing: What it is, What is not, in 1860. These notes became the true basis of nursing research and practice. Jean Watson developed the Theory of Human Caring between 1975 and 1979. This theory brings significance and focus to nursing as an up-and-coming discipline and separate health profession with its own distinctive ethics, knowledge, and traditions. Dorothea Orems Self-Care Deficit Nursing Theory comes from her belief that people have the ability to care for themselves and their families. Her theory explains that nurse have to supply the care patients need when they cannot care for themselves (Im Ju Chang, 2012). Nursing philosophy represents the belief system of the profession that provides perspectives for practice, for scholarship, and for research. Nursing philosophy is the overview of the basic beliefs about nursing practice. It is the outline of the viewpoint regarding what nursing is, what it aims to be, and how that can be realized. Nursing philosophy examines the nature of nursing, the nurse-patient relationship, and the heart of nursing. It serves as a guide for nurses in learning and practice, and evaluates that practice. Nursing philosophy is as active picture of who we are, what and how we know; and of what we do within the discipline (Kikuchi Simmons, 1994). A nurses philosophy consists of the principles and approaches towards life that the nurse upholds and how it affects her outlook on nursing practice. Philosophy leads the nurse to act in a particular way. Ernestine Wiedenbach is credited with developing the conceptual model of nursing called The Helping Art of Clinical Nursing. Wiedenbach theorized that there are three essential parts of nursing philosophy. The first is the respect for life; the second is value for the pride, worth, independence and distinctiveness of every person; and the third is promise to act on personally and professionally held convictions (Wiedenbach, 1964). Virginia Henderson, best known for her Definition of Nursing, believed that the nurses main purpose is to take care of patients needs and to assist them with day to day activities. These are activities that the patients would have been proficient in doing had they not been sick or debilitated (Castledine, 1996). Many facets of nursing have changed since Florence Nightingale and Virginia Hendersons era. However, the necessity for truly understanding about overall patient care remains the same. It is because of these nurses and their interest and concern for the theoretical and philosophical aspect of nursing, the nurses and providers today are able to treat their patients Alligood, M.

Calculate the percent of utilization of the graduate student P= 4/6 = 2/3 = . 6667 percent utilization ii. Determine the average number of students in the system ?= 4 per hour ?= 6 students helped an hour Ls= 4/ 6-4 = 4/2 = 2 students in the system on average. iii. Calculate the average time in the system Ws= 1/ 6-4 = ? = . 5 hours average time in the system iv. Find out the probability of four or more students being in line or being served P0= 1 – 4/6 = 1- 2/3 = . 33 probability that there are 4 or more students being in line or being served. . Before a test, the arrival of students increases to five per hour on the average. ?Compute the average number of students waiting under this scenario. Lq= 4^2 / 6 (6-4) = 16/ 12= 1. 33 student waiting in line on average. (b) Â  What are the three characteristics of a waiting? line system? 1. Arrivals or inputs to the system: these have characteristics such as population size, behavior, and a statistical distribution. 2. Queue discipline, or the waiting line itself: characteristics of the queue include whether is it limited or unlimited in length and the discipline of people or items in it. . The service facility: its characteristics include its design and the statistical distribution of service times. —————— ———————————————————————– Question 2. Radovilsky’s Department Store in Haywood, California, maintains a successful catalog sales department in which a clerk takes orders by telephone. If the clerk is occupied on one line, incoming phone calls to the catalog department are answered automatically by a recording machine and asked to wait.As soon as the clerk is free, the party who has waited the longest is transferred and serviced first. Calls come in at a rate of about 12 per hour. The clerk can take an order in an average of 4 minutes. Calls tend to follow a Poisson distribution, and service times tend to be exponential. The cost of the clerk is $10 per hour, but because of lost goodwill and sales, Radovilsky’s loses about $25 per hour of customer time spent waiting for the clerk to take an order. ?= 12 ? = 15 (a) What is the average time that catalog customers must wait before their calls are transferred to the order clerk?Wq= 12/ 15 (15-12) = . 2667 average time to wait before transferred (b) What is the average number of callers waiting to place an order? Lq = 12^2 / 15 (15- 12) = 3. 2 average number of callers waiting to place an order (c) Radovilsky’s is considering adding a second clerk to take calls. The store’s cost would be the same $10 per hour. Should it hire another clerk? Explain your decision. Yes they should hire another clerk because the customer average wait time and average number of callers waiting to place an order indicate that a second representative is needed.

Influence the Age of Exploration Had on the New World and Africa Essay

The Europeans, during the Age of Exploration, had an influence on both the New World across the Atlantic Ocean, and the much closer continent of Africa. In both Africa and the New World, Europeans had similar influences in that they negatively affected the natives in their search for riches such as spices and precious metals, and wherever they traveled they would spread Christianity to the natives. One example of this is when Cortes arrived in the Aztec empire he demanded they convert to Christianity, and when the Portuguese began colonizing east Africa it didn’t take long for the Jesuits to come. However the spread of diseases, the slave trade, and the economic takeover of natural goods differed in the New World and Africa. Africans were accustomed to the diseases of Europe, the natives of the Americas were not enslaved as the Africans were, and the Europeans were unable to take over the natural resources of the Africans because of their stronger government structure. In both the New World and Africa the Europeans were constantly in search of riches and devoted to the spread of the Christian faith. Christopher Columbus’s first expedition across the Atlantic was in search for spices. In Africa, they wanted precious metals such as gold. In the New World and Africa the native people had their land taken from them by the Europeans so that they could search for these valuable things. When the Portuguese were settling the east African coast they forced the leader of the Mwene Mutapa to grant large sections of land to their officials. In the New World the natives also lost land but the Europeans were much more forceful. When Cortes came to the Aztec city of Tenochtitlan a battle broke out that killed the majority of the local population. This negatively influenced both the two worlds. Another influence on the native population was the spread of Christianity. The Spanish had forced the Aztecs to convert to Christianity but when they refused, a battle broke out. In Africa Jesuits had started to come to the Portuguese settlements in hopes to convert natives. Although the Portuguese Jesuits were less violent than the conquistadors, both Africa and the New World were influenced by the spread of Christianity European exploration and colonization had different effects on the New World in contrast with Africa in regards to disease effecting society, the effect politics had on slave trade, as well as the economic takeover of natural goods in the New World. European diseases alone wiped out at least half the population of the Americas. When Columbus arrived to  Hispaniola the population was 100,000 but just 77 years later and it had dwindled to 300. Diseases had a massive impact on the New World whereas it had little to no effect on Africa. Due to the fact that Africa is so much nearer to Europe, they had more exposure to these diseases, specifi cally Malaria. African ancestors were able to build up a stronger immunity to the diseases carried be European therefore it had contact with Europe via the Trans Saharan Trade Route, it is believed that African ancestor’ exposure to many diseases created resistance in further African generations. Therefore, the African population was much less effected by diseases carried by Europeans explorers than the Native Americans. When the Europeans arrived to the Americas they were able to take the population by storm. The Native Americans were weak and defenseless compared to the Spanish, who had horses and modern weapons. Columbus himself called these people â€Å"naà ¯ve innocents.† Due to their innocence it was easy for the Spanish to capture them and put them to work in sugar cane fields. This was quite the opposite however of the slaves captured from Africa. These slaves were actually negotiated between African slave traders and the Europeans. Slave merchants were paid with East Asian textiles, furniture, and spices. This differentiates from the completely forced capture of the slaves in the Americas because Africa was already well established. The indigenous people had a strong form of government and trade was strong along the Trans Saharan Caravan Trade Route. The Native Americans on the other hand did not have a stable enough government to withstand the Europeans. Looking at this form and economical stand point, natural resources were taken over in the Americas by the explorers. They harvested all the sugar cane, gold, and silver for their own trade purposes. The Indians were forced to work the fields, not own them like before. In Africa though, due to its strong establishment, Europeans could not forcibly take resources. Instead they negotiated and traded with slaver merchants to get what they wanted: slaves who would be forced to go the Americas to be the labor force for harvesting the natural resources there. The New World and Africa were affected by the Europeans during the Age of Exploration in similar and opposite ways. Both were negatively affected in the European’s search for riches and spices. They were also influenced by the spread of Christianity by the Portuguese Jesuits and Spanish conquistadors. There were differences however in the way European  diseases effected the foreign populations, how slavery in Africa was handled compared to the New World, and the economic takeover of natural goods in the societies.

Stem Cell Success or Moral Dilemma Essay - 1599 Words

â€Å"Stem cell research saved my life!† For some this is true, and for others its a moral infringement. For many religious groups this has been a very controversial, unethical way for scientist to commit murder in the name of science. On the contrary for those riddled with diseases its a chance at a new life. Scientist have come so far over the last few decades in their research, if we now stopped researching stem cell therapy, it would be an enfeeblement to medical technology.

And there is adult tissue or somatic stem cells. Bot h types of stem cells are particularize by their strength and potential to severalize into different cell types I.E skin, bone, muscle etc. (Crosta). Adult stem cells exist inside the body after embryonic development and are inside various different tissue types. Stem cells can also be found in tissues like the brain, skin, liver, blood, blood vessels and skeletal muscles. These cells remain dormant until stimulated by injury or disease. Scientist have an understanding that adult stem cells can divide endlessly. This particular trait allows them the capability to generate a range of cell types from the original organ (Crosta). There are many places to obtain stem cells from: bone marrow, fat cells, umbilical cord blood, adult blood, olfactory nerve endings, skin cells, and the human embryo. There are two methods for retrieving a stem cell, using an embryo that has already been conceived or cloning an embryo using a cell from a patient and a donated egg (embryonic stem cells).
