    Kimberly, Thank you for your post. In my capstone paper I presented a paper about teaching a subject on cultural diversity for nurses. I want this class to be an in-service class just like yours. A 45 minutes class and not a 4-8 week semester class would be best for me to teach. I am not ready to teach beyond 45 minutes. I think teaching comes with time and experience. I would not like to give a boring lecture, but a person has to start somewhere. Sorry about the way things are happening at your work place, but you will overcome and succeed. A prior class on capstone fundamentals would have enlighten me on how to write a capstone that is agreeable.…

    assessment tools Epic provides a nursing flowsheet built into the shift assessment for nurses to chart on any skin issues of the patient. Not only is it standard but it is also required for the nurse to chart every two hours on the prevention or repositioning of the patient. QI data has shown that repositioning and turning the patient every two hours will prevent HAPUs. Collecting this measurable data through Epic has helped improve health care services to prevent further HAPUs from happening. On the unit, HAPUs have significantly decreased from last year by enforcing the nurses to proactively prevent skin breakdown by continuing to use of tools and following skin protocols. The results and statistics from the QI data collected over the…

    A person's body needs it's kidneys to filter blood, create hormones to make bones strong and blood healthy. When kidneys fail, treatment is necessary, and there are only two options: a kidney transplant or dialysis. Dialysis first became a practical treatment in the 1960's. There are two main types of dialysis, hemodialysis and peritoneal dialysis. Both types of dialysis filter blood of harmful wastes, extra salt, and water. Hemodialysis does this with a machine. Both require a special diet and both types have risks and benefits. Dialysis is not always permanent, it depends on if the disease is chronic (long-term) or acute (short-term). My grandfather is currently on hemodialysis and at first I was completely clueless about it until I researched.…

    The Centers for Disease Control and Prevention list Nephritis, Nephrotic Syndrome, and Nephrosis as number nine in the top ten leading causes of death among Hispanic Americans (Hispanic or Latino Populations, 2015). Each of these conditions is a type of kidney disease in which the kidneys cannot effectively filter wastes from the blood. Chronic Kidney Disease, or CKD, can lead to many severe health problems. Because the kidneys filter the blood, CKD can cause the body to retain fluid that can lead to swelling, high blood pressure, or fluid in the lungs (National Chronic Kidney Disease Fact Sheet 2014, 2014). CKD can also cause potassium levels to rise to dangerous levels which inhibit the beating of the heart which can lead to death (National Chronic Kidney Disease Fact Sheet 2014, 2014). The kidneys are vital organs that contribute to keeping many different organs in your body in proper working order.…

    Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. They also make hormones that keep your bones strong and your blood healthy. When your kidneys fail, harmful wastes build up in your body, your blood pressure may rise, and your body may retain excess fluid and not make enough red blood cells. When this happens, you need treatment to replace the work of your failed kidneys. (National Institute of Diabetes and Digestive and Kidney Diseases, National Institute of Health, 2011). When kidney disease progresses, it may eventually lead to kidney failure, which requires dialysis or a kidney transplant to maintain life. (National Kidney Foundation, 2012).…

    End stage renal disease can manifest as a variety of symptoms that include general malaise, weakness, dry skin, pruritus, and headaches, loss of appetite, and sometimes nausea and vomiting. Also, drowsiness, confusion, muscle twitching or cramps, easy bruising, nosebleeds, edema, low urine output, etc. If kidney failure is untreated, it can develop to seizures, coma, and death. With that being said, we have to remember that when people deal with life challenges, they experience emotional anxiety especially if encounter a difficulty for the first time (Clarice and her family). They experience fear ("loose a wonderful mother and grandmother much too soon"), anger ("She felt even God had let her down "), grief and depression (Hadn’t she always…

    Acute Renal Failure Essay

    Acute renal failure (ARF), also know as Acute Kidney Injury/Impairment (AKI) is described as a condition where there is a rapid decline in kidney function which results in an increase in accumulation of waste materials in the body and decreased urine output, usually over hours to weeks, occurring in a person with or without a previous pre-existing renal disease (Van Biesen, W., Vanholder, R., & Lameire, N., 2006). Acute loss of renal function can be due to poor perfusion to the kidneys, called prerenal failure, from an obstruction of urine flow from the kidneys, called postrenal failure, or from complications from within the kidneys called intrinsic renal failure (Rahman, M., Shad, F., & Smith, M.C., 2012). Prerenal acute failure can occur…
