In this assignment the question that has been formulated from the extracted case study is “Why are nurses promoting obese patients to take on a healthier lifestyle?” To gain the information and evidence needed to answer this question, several Journal articles, books and online resources that have been searched for through the SHU Library Gateway, Inter-nurse and other online nursing databases will be used. The information and evidence gained from these search engines will establish the reasons as to why the relationship between evidence and knowledge being used in practice and study is so important. This assignment will also show how the journal articles, books and online resources have been searched for and how they are relevant to the question in hand with appropriate referencing. Aveyard and Sharpe's (2009) explanation of what Evidence based practice is: Evidence based practice is practice that is supported by a clear, up-to- date rationale, taking into account the patient/client's preferences and using your own judgement. If we practice evidence based practice then we are set to give the best possible care. Why is using evidence and knowledge being used in practice and study so important? According to the NMC (2008) we should follow their code of conduct which advises that we should use the best available evidence, by doing this we shall deliver care that is based on the best available evidence or best practice. This code plays a vital part in nurses treating patients with obesity and how they promote their future health. When nurses come in contact with obese patients, it is their role to give advice on weight loss, including healthier eating and exercise to increase their overall fitness levels. For the nurses to be able to give this advice and encouragement, they must be equipped with the best and most up to date knowledge on how to deal with obese patients, the reasons behind their obesity and the effects it has on the patients now and in the future. When giving advice, nurses need to be able to explain the reasons as to why they are giving the advice and the rationale behind it. The advice must be up to date and based on the best available evidence according to Aveyard & Sharpe (2009). This is important when suggesting healthcare products and services to their patients as it enables the patient to be informed of the most up to date and best evidence based products and services available to them. This then provides the patient with the confidence and ease of mind knowing that they are receiving the best advice from their nurse. Evidence based practice is also important in academic studies. Fostering nurses the culture, knowledge and capabilities to execute evidence-based practice will produce a nursing profession that will influence policy and practice for future generations. (Cleary-Holdforth J, 2008, page 43) If students are not taught the most up to date and best evidenced based information then they would be going into practice not being fully informed or equipped to give the best possible nursing care to their patients nor would they have the knowledge to be able to progress and implement future changes to practice or policy. For evidence based practice, we need to look at the challenges of identifying trustworthy knowledge. Evidence needs to be clarified as whether or not it is of good quality and a best source. We can check the quality of the evidence by checking to see if the author is a reputable author who has relevant qualifications in the topic being discussed, whether they have any vested interested in the topic or if they are discussing opinions rather than facts, all of which can could hinder the quality of the information. To the answer the question for this assignment, 5 sources of information were taken from journals, books and online sources, these sources were found by completing a literature search in the SHU Library Gateway and Inter-nurse. Keywords were inserted...
