Avail online Free Sample solution for Nursing Australian Society
Question: What type of support surface is the most effective in preventing pressure ulcers in patients admitted to the acute care setting? Answer: Background The Australian society is diverse as it comprises of a variety of populations experiences regarding different diseases. One of the most prevalent conditions of illness is due to the occurrence of pressure ulcers (McInnes et al. 2015). It is a wound in which the death of the skin and the underlying tissues occurs due to the pressure which is not relieved. There are several factors that contribute to the progression of pressure ulcers. A pressure ulcer can develop within twenty four hours of the preliminary pressure. It is very painful and causes immense suffering to the patient. The patients quality of life gets affected. The treatments of ulcers might require surgical methods like colostomies, amputations and debridement (Demarr et al. 2013). Therefore, the healthcare sector has categorized the patients from the non-English backgrounds, as the patients who belong from the background which is culturally and linguistically diverse and particularly includes the Indigenous and migrant ba ckgrounds. It is quite annoying and challenging for the nursing experiences and it is quite complex for professionals of nursing to tackle the patients who are suffering from pressure ulcers and are admitted to the acute care setting in Australia (Engels et al. 2016). The explicit and severe challenges that are experienced by the nursing professionals include barriers of language, delivery of quality care, bureaucratic system of healthcare, relationship with the patient and the nurses, together with dealing with their personal and family stress. Attaining the knowledge of treatment is considered necessary for the nurses in all the aspects. This can be performed by the recognition on the basis of knowledge in the place of work and comprises of the sources such as health workers, the patients as well as their families, who can extensively assist in attaining the knowledge (Schoeps et al. 2016). This assessment is concerned with the nurses who face acute challenges while working with t he patients suffering from pressure ulcers and includes a systematic review of significant literature. Research Question What type of support surface is the most effective in preventing pressure ulcers in patients admitted to the acute care setting? A question of research characteristically assists to direct and guide a program of research. Hence, it has to be clear as well as focused and it should encompass the combining of the different resources for presenting the argument. Formulation of a question that is associated with research should encompass the execution of preliminary research for obtaining a general idea of the subject, based on the journals which are peer-reviewed. In order to formulate question, the framework of PICO has been utilized (Mallah et al. 2015). The PICO framework is applied in the evidence-based practice for framing the questions which are associated with the healthcare sector. It is also used to develop the strategies of literature search. The acronym of PICO is as follows: P- Population or Patient I- Intervention C- Comparison O- Outcomes The questions that are clear and well-focused are necessary to search the significant evidence and identify the correct resources. Hence, the framework of PICO assists in the identification of the most important elements associated with the questions and makes the statement of the question relevant (Chaboyer and Gillespie 2014). In this assessment, the comparison is not included due to lack of its scope. Therefore, the framework utilized in this assessment is PIO framework, which only considers the patient/population, intervention and outcome. The PIO acronym utilized for this assessment is as follows: P- Patients admitted to the acute care setting I-Support surface O- Preventing pressure ulcers The development of a research question is involved with the concept of developing a research hypothesis. Predictions were made about the phenomenon of research examination which forms the research foundation. Specific predictions were made with the help of hypothesis with respect to the direction and nature of the association that exists in the between two different variables. In order to draft the Question of research in the assessment, insight was given to the research hypothesis that stated the acute challenges that are faced by the nurses while tacking the patients suffering from pressure ulcers on a daily basis. The testable and quantifiable parameters were evaluated and included the individuals of different population. At the end, the experience of the staff was taken into consideration that helped to draft the final question, integrating the other two hypotheses and resulted in the stating of the research question What type of support surface is the most effective in preventin g pressure ulcers in patients admitted to the acute care setting? Importance of Research Question The process of research is initiated by having an interest in a particular or specific topic. Though, the familiarity with the subject defines the correct question of research. The scarcity of the apparent knowledge raises the question within the area of study and the importance of the research question is defined by investigational research. It is necessary to identify the boundary between the lacks of knowledge and the apparent knowledge that assists to find out the clinical doubts rationalizing the significance of the research question. In this assessment, the importance of the research question lies in the actuality that it assists to find the type of support surface is the most effective in preventing pressure ulcers in patients admitted to the acute care setting. According to the framework of health service for the patients admitted to the acute care setting in Australia, it has been discovered that a large number of individuals are suffering from pressure ulcers. These figures are expected to increase further in future as well as present challenges for the providers of healthcare service with respect to requirements of support and devices that are safe in terms of all the aspects (Fleming 2015). Because of the larger diversity populations residing in Australia, a variety of challenges come into view for the professionals of nursing that are persuaded by the appropriate responses and individual goals of health. The explicit factors of challenging include the cultural, environmental, spiritual, social, economic and emotional that intertwines across the diverse profiles of healthy in a variety of ways to influence the behavior of the patients together with their family members and verify the role of the nursing professionals in supporting the t reatment and providing care (Lachenbruch et al. 2016).. The challenges that are faced by the nurses while providing care to the pressure ulcer patients of different backgrounds encompass the patients together with their families. The major challenges comprises of communication, assessment, restrictions of working with the interpreters and the provision of holistic care. Privacy and education are the issues that were associated with the patients. Aggression and visiting were the issues with the family members of the patients who are admitted to the acute care setting. Types of workers of health, obligation of the health officials as well as flexibility of the organization are the issues with the system of healthcare (Huang et al. 2015). The willingness of commitment and the stipulation of care are the keys to the care of the patients who are admitted to the acute care setting. The nurses have a conventional sight of the patient. In order to improve the proficiency of the nurses with respect to the care of the patients with ulcers and provide them the treatments like static support surfaces and dynamic support surfaces to a much more extent. Experience could assist the nurses in this aspect by developing knowledge within the episodes of care by facing inconsistent challenges. By means of a proper training along with education, the development of understanding and knowledge of care for the patients who are suffering from pressure ulcers is essential (Barry and Nugent 2015). Search Strategy The search strategy is initiated with the searching of a database from which the data is gathered in a structured manner. The available data is arranged in terms of a model that supports the processes and it requires collection of information. In this assessment, the collected of data has been done with the help of PubMed. It is a free search engine along with the accessing of the MEDLINE database of references and abstracts. The database is maintained by the United States National Library of Medicine in association with the National Institutes of Health for retrieval of information. The next step of the search strategy is involved with the identification of the keywords. This assessment utilized the PIO strategy for the database search string along with its implementation. Appropriate keywords were utilized in variety of combinations as indicated by the framework for searching the database and extracting the research articles that are required for answering the articles of research. The identification of relevant keywords was performed by utilizing the PICO framework and it assisted comprehensively to combine the appropriate search terms with respect to the research articles. The role of connecting words has been played by the Boolean operators that are positioned between the search terms to narrow or expand the search. In this assessment, the Boolean operators utilized are AND, NOT and OR. AND helps to find the citations that are comprised of all of the specific keywords. NOT assists to find the citations that contain specific keywords. OR helps to find the citations that contain either of the keywords that are specific. A stepwise guide to use the Boolean operators and keywords for searching the selected database is search string. The search strings like? and * have been utilized on a trial and error basis for searching the appropriate articles. Truncation was utilized for expanding the process of search as it helped in the identification of variations in the words. The symbols utilized for the search were?,*and $ as nurs*for retrieving nurse and nurses. In the search process, abbreviations used was PPU for patients with peptic ulcers. Wildcards were utilized for trying different spellings for patient skin colour and color were searched with the ? symbol. These all were implemented on a trial and error basis but could not retrieve relevant results of the search. Table: Searched Keywords P Population / Problem I Intervention O Outcome Patients with Pressure Ulcers Acute challenges Communication challenges Responsibility of the Nurses Capabilities Support surface Nursing knowledge proficiency Professional ethics Moral values Patient care Patient compliance Patient contentment Efficient care Respect and dignity A detailed account of the search strategy and the results has been provided in the appendix. Results The appropriate research articles retrieved by means of the search keywords have been provided below. Alanen, J. and Muli, R., 2015. ASSESSMENT TOOLS FOR PRESSURE ULCERS.

Discussion This research assessment has enhanced my understanding regarding the evidence-based practice for nursing. The identification of related research articles and writing a research question has helped me enormously in understanding the challenges that are faced buy the professionals of nursing. It has helped me to discover the ways to deal with the challenges that are faced by the nurses in acute care and long-term settings for the care of the patients having pressure ulcers. Besides this, I have learned the methods of database search by utilizing the key features of Abbreviation, Boolean, Wildcard and truncation. I have developed a comprehensible knowledge of the process of inclusion as well as exclusion of the key search words and finding out the appropriateness of the searched literature. My understanding has intensified and my skills have been enhanced concerning the search string for the literature that explains the profile of nursing care for the patients suffering from pressure ul cers, who are admitted to the acute care settings. The experiences of the nurses with these patients sought for the knowledge required to offer care oriented around an individual and conventional viewpoint. The nurses faced a number of challenges and quandaries with the patients as well as their families while working with these patients (Flood et al. 2015). For accommodating the patients who are suffering from pressure ulcers, it was considered that adequate knowledge and guidance is necessary. To prepare the future nursing professionals to face this challenges efficiently, they should be exposed to the present situation and train them to make them capable enough to face these acute challenges. Besides all these, the healthcare system should enhance its flexibility, the number of health workers must be augmented and interpreters should be easily available (Ozyurek and Yavuz 2015). Sometimes the issue of communication gap arises as a hurdle in the treatment and care of the patients and as a result, the relationship of the patient and the nurse is never developed. An improper communication leads to gaps in the process of treatment and care and it sometimes becomes critical if the patients are suffering from long-term diseases (Cullum et al. 2013). The nurses possess sympathy for the patients and have an optimistic attitude towards facing the acute challenges associated with the care of the patient. In order to enhance the effectual treatment of the patients, the nurses reveal the readiness to augment their knowledge for learning the cultural diversity (Moore et al. 2014). They strive constantly to attain the capability to work within the perspective of the patient. They work on the efforts to become more well-informed and aware that makes easy the communication with the patient population together with their families. Since this investigational learning occurred in a variety of workplaces, there were possibilities of spreading of the erroneous cultural information (Barry and Nugent 2015). This raised the actuality that there is a necessity of programs of staff improvement that provide opportunities to the nurses as well as the nursing managers to talk about the concerns of patient care (Lachenbruch et al. 2016). As the worldwide mobility of the population of patients increases in the facilities of acute care in Australia, its population has become more ethnically diverse than ever. The professionals of nursing staff are required to work with the patients (Schoeps et al. 2016). Consequently, it is becoming gradually more challenging to the nurses to provide acute care to the individuals who are suffering from pressure ulcers and provide them with support surface such as static or dynamic support surfaces depending on the condition of the patient (Engels et al. 2016). The recognition of the experiences of the nurses for the caring of the patients who are in the acute care settings has a noteworthy contribution towards the knowledge of nursing (Chaboyer and Gillespie 2014). This can be performed by the recognition on the basis of efficient knowledge in the place of work and comprises of the sources such as health workers, the patients as well as their families, who can extensively assist in att aining the knowledge in an efficient manner.

Development of the cotton economy in the South 1776-1860 Essay
Development of the cotton economy in the South 1776-1860 - Essay Example The Northern merchants reaped huge gains from cotton trade as they were engaged in buying cotton from farmers and exporting it to England in exchange for manufactured products. According to Seavoy (184), the trade business in North American states was actually an international affair as those in the North would export to foreign markets the cotton they had bought from the southern farmers. The economic success for both the north and south lay on the support of the southern slaves, which saw the emergence of capitalism, slavery/ forced labor and the civil war. This paper looks at the impacts of cotton farming and the long term effects it had on the American history. Development of the cotton economy in the South The economy of North America and South America differed in that the northerners chose manufacturing system while the southerners chose landowning aristocracy. The aristocratic federal system allowed a high degree of independence as labor was drawn from various fronts. Demand f or labor rose sharply in the seventeenth and eighteenth centuries in both North and South America. Northern immigrants came from Europe and were excellently absorbed into society while Southern immigrants came from Africa and they were not absorbed. ... They were sold to Southern American planters. Instead of paying the immigrants themselves, planters in the South paid the ship captains. Due to capitalism, the planters overworked the immigrants in order to pay higher prices to ship captains. Southern immigrants as well as their children became slaves for their entire lives. The slaves were increasingly used to grow cotton in the South. Cotton accounted for fifty percent of all American exports and the South generated more than fifty percent of the global supply of cotton in 1840. This enormous production, as Walton and Rockoff, (p 125) and say held many foreign countries in partial repression. By then, Britain was the leader in terms of industrial power, and its most pertinent manufacture was cotton cloth. Southerners repressed nations like Britain as they perfectly knew that Britain was attached to them mostly by raw cotton. This dependence gave them an invigorating sense of power. The South grew rapidly as a result of cotton and d iversified agriculture. The rapacious craving for cotton in Lancashire matched the increasing production in the South driven by vitality of slave institutions and availability of cotton growing land. The immorality of enslaving Africans has continuously haunted American economic history. African enslavement became a prime factor in antebellum politics and a pertinent aspect in the civil war. Even today, the role of blacks in American history and economy persists. The antebellum Southern encounter was largely as a result of peculiar slavery institution. Cotton economy restrains industrialization in the south Cotton economy in the South

Discuss the role of histopathology in the diagnosis and prognosis of Essay
Discuss the role of histopathology in the diagnosis and prognosis of adenocarcinoma of the colon - Essay Example According to Burns (2011) adenocarcinoma of the colon is the cancer that affect the gastro intestines especially its mucosa. Development of adenocarcinoma is associated with development of polyps. Polyps are the growth that are found on the inner side of the colon and protrude into it. These structures form when epithelial cells that line the colon, change to abnormal. This process of change in the epithelial cells is known as mutation. In any living organism, the cells are programmed to generate, multiply, mature and die in a normal way (Willet, 2005, 29). However, in the case of the polyps, there is inconsistency with the designed program of the cells because polyps are permanent. Their existent also makes the death of other cells impossible and hence there is an accumulation of cells in the colon. This has a negative effect on the functioning of the body because it renders conducive supply of oxygen and consumption of nutrients to the cells. This then leads to accumulation of imma ture cells and consequent development of more polyps. If not treated, the polyps develop into the tumor in the inner tissues of the colon. Some of the symptoms of this cancer include; rectal bleeding, constipation, anemia, angina amongst others. Histopathology of the tumor According to Greaves (2011, 29) histopathology of the adenocarcinoma is achieved through taking a biopsy from the colon tissues and carrying out various procedures, which help to differentiate between normal tissues from cancerous one. Fixation of the cells is the first step during specimen processing. Formaldehyde is used to fix the specimen that will undergo pathology study. The purpose of this chemical is to preserve the cells by the process known as irreversible cross-linking of proteins. In this process, the amino groups are cross-linked in proteins through the formation of the methylene bridges. The aim of this process is to retain the integrity of the cells. It ensures that the whole process of specimen pre paration does not distort a normal cell. As such it ensures that at the end of the test, a normal cell is clearly differentiated from abnormal one. However, the disadvantage of fixation through formalin is that, it may degrade RNA, DNA and other components of the cells. Hence it requires for the recommended protocols to be followed when carrying out such process. According to Jones and Morson (2003) an alternative way of fixing specimens is by using suitable freezing medium such as nitrogen. This method is mostly used to preserve the tissues. It is used in conjunction with staining methods such as antibody linked immunoflorescence staining. This process is important in diagnosis and prognosis because when the integrity f a specimen retained, an accurate conclusion is drawn at the end of the examination of the specimen. This then will show whether the cells are cancerous or not, which will later help in forecasting the course of the disease. After fixation, dehydration and clearing o f the cells follow. The importance of this step is to ensure that cells are dry hence easing the process of specimen sectioning. It eases the process sectioning the specimen for easy visualization through the microscope. In histopathology, this process is important because when cells are cut into the recommended thinness, the various infections and abnormalities can be identified accurately when the specimen section is viewed under microscope (Keggar, 2006, 237). This helps

LIFE CYCLE - PLASTIC BAGS Essay Example | Topics and Well Written Essays - 2250 words
LIFE CYCLE - PLASTIC BAGS - Essay Example They are portable, light weight, reusable and easily disposable. However, use of plastic bag has always been a controversial issue given it affects the animal and marine life in many adverse ways and is conventionally manufactured from non-renewable natural resources. Besides, there are many other concerns associated with the use of plastic bags that are of huge significance to the environment and ecology. Use of plastic bags has been globally condemned and criticized with reasonable arguments. This paper elaborates the life cycle of plastic bags and critically analyzes the environmental effects of each stage of their life cycle. Furthermore, various alternatives that can help eliminate the draw backs of plastic bags while maintaining the capacity to deliver the same usability are also enlisted in the paper. All bags are supposedly light in weight, so they inflate once air is filled in them. This property is not limited to just plastic bags. Indeed, all bags irrespective of their material are light weight, and this property fundamentally makes them suitable for use in everyday life for all purposes. However, plastic bag has a significant edge over other types of bags in that they are purely impermeable and are often transparent. This is what differentiates plastic bags from other bags because they offer the user the ease of carrying liquids which many other types of bags do not. The strength of plastic bags is much more than that of a paper, so they are used for carrying significantly larger weights than other bags. Plastic bags are good in resisting tensile stresses. They bear sufficiently larger tensile forces than any other kind of bag. This makes them the best carrier among the variety of carriers available. They come in a variety of sizes. ââ¬Å"Small bags have lower visibility th an large bags and thin light (HDPE) bags snag more easily than heavier (LLDPE) bags.â⬠(Verghese, Jollands, and Allan, 2008, p. 10).
