Management of hypoglycemia - Essay Example Diabetes is increasingly common throughout the world.Its prevalence is well over 5% in many developed countries and is rising in the United Kingdom.While talking about its prevalence,it is to be remembered that diabetes is caused by our genes and our personal environment, which is created by our lifestyles. For people with diabetes, whether type 1 or type 2, the disorder can have a profound influence on all aspects of life and can affect most organs of the body. There is no cure for diabetes, and once occurs, it is present for life. The increasing appreciation throughout the healthcare industry for clinical decisions to be driven by sound scientific evidence represents an opportunity for the patients, practitioners, and healthcare planners alike in that it shapes the delivery of care on the basis of evidence of effectiveness. The past two decades have seen considerable progress in producing evidence to support treatments aimed at reducing the risk of diabetes and its complications. T his indicates a shift of focus from treatment of effects to treatment of cause, where prophylactic interventions are more important than just therapeutic measures. This means caregiving now does not await the disease to happen; rather, the care tends to identify population or individual who would develop diabetes in a later life (Foster, 1998, p 2069-2070).Definitions: Diabetes mellitus occurs either because of lack of insulin or because of the presence of factors that oppose the action of insulin. Therefore, it can be defined as a chronic disease caused by inherited and/or acquired deficiency in production of insulin by the pancreas or by the ineffectiveness of the insulin that is produced. The result of insufficient action of insulin is an increase in blood glucose concentration or hyperglycaemia. This increased glucose would damage many of the body systems, most significantly blood vessels and nerves. Data from genetic, epidemiological, and aetiologic studies have led to the impr ovement of the understanding of the aetiology and pathogenesis of diabetes. From my experience in the clinical placement, I have come across patients during clinical practice with varied presentations. Whatever may be the mode of diagnosis, persistently elevated plasma glucose in the fasting state would lead to the diagnosis of diabetes mellitus even if the patient is asymptomatic. In the ward while working with the patients of diabetes, frequent monitoring of plasma glucose and adjusting the diet or medication is a normal routine nursing activity. I have see a venous plasma glucose concentration of 140 mg/dL in at least two separate occasions or plasma glucose concentration of 200 mg/dL 2 hours following ingestion of 75 g of glucose would constitute a diagnosis of diabetes mellitus(Foster, 1998, p 2080). Insulin: Diabetes is treated with insulin in the inpatients with or without oral hypoglycaemic agents. Since the disease at least partly results from insulin deficit, insulin is required for many patients with diabetes mellitus type 2. If no oral agents are used for treatment, all diet-responsive type 2 diabetics must be treated with insulin. My observation suggests that it is fairly easy to control the symptoms of diabetes with insulin, and as a nurse working in the ward, I know it is difficult to maintain a normal blood sugar throughout the day even with the use of multiple injections. It is also to be mentioned that the patient treated with insulin by injection cannot reproduce the physiologic changes in a normal patient in response to a diet load. Thus, if enough insulin is given to keep the postprandial glucose normal, too much insulin will be present during the postabsorptive phase, and hypoglycaemia will result. As a result, insulin therapy is guided mainly by adjustments

Obama's Policy in Afghanistan Essay Example | Topics and Well Written Essays - 2000 words

Obama's Policy in Afghanistan - Essay Example Obama was likely to bring the ray of hope for the people of America. But for Obama it was a test of all his managerial and leadership skills. One of the major challenges that newly became president faced was making policies for Afghanistan. But before discussing Obama’s Afghanistan policy in detail it is very important to have a clear idea about the major incidents in Afghanistan over the past few years and how intensely America is associated with Afghanistan. After 9/11 America got itself directly involved in the biggest war against terrorism in Afghanistan as the country believed that Osama Bin Laden was the master mind behind 9/11. Laden was the founder of terrorist group Al Qaeda and was hiding in Afghanistan where he got support from Taliban. Thousands of US troops were deployed in Afghanistan with the objective of defeating Taliban and Al-Qaeda by catching Osama Bin Laden and other leaders of Al Qaeda and Taliban. On December 07, 2001 Kandahar which was a Taliban stronghold fell down and Bin Laden along with Mullah Mohammed Omar who was a Taliban leader escaped. On December 16 Tora Bora, the mountain cave where Taliban and Al Qaeda took shelter, also fell down. An interim government of six month was formed in Afghanistan and Hamid Karzai, was selected as the chairman of this government. In 2002 Karzai was elected as president of Afghanistan, although other Afghan factions were not happy regarding this. But on January 04, 2004 they a ll agreed on a constitution which made the way for elections (Guardian, A chronology of events in Afghanistan since the attacks of September 11 2001). Finally in October presidential election took place and in November Karzai was declared to be the winner.
