SECTION AStep 1: Write 3-4 sentences answering the following questions:Identify and describe a recent change occurring in your workplace. It could be a change in the levels of staffing, a change in policy, such as time off or tuition reimbursement, a change in use of equipment or supplies, a change in charting/computerized medical records, etc. Describe the change in 4 sentences. 1 of the sentences should address the rationale for the change. Step 2: Begin researching scholarly articles for the past five years related to the change issue identified in Step 1. Complete a 6 columns table of the references found including the following: Author Last name, First Initial (year)Title of article.Title Of Publication,Volume # (Issue #)pages of the article. Submit the Reference List Table to your instructor through the “course assignment area”. A minimum of (6) scholarly references are needed to complete this assignments- you may find more. SAMPLEChange Issue: Low census staffing policy.Currently, staff go home when the patient census is low based on tenure, so that the same staff are continually going home resulting in a lower paychecks for these nurses. The proposed change is to rotate all staff to leave when the census is low, regardless of tenure so the burden of potentially lower pay is shared among the entire staff, and not the same few.Author Last Name, First Initial.(Year).Title of Article.Title of Publication,Volume #(Issue #),Pages.1. Smith, A.(2011).Low census staffing: Making it fair.Journal of Scholarly Affairs,1(4),110-113.SECTION BWritten communications in nursing incorporates the use of evidence or research published in the literature from scholarly references. Scholarly references are defined as work which is peer reviewed and published in a professional journal. For example, any of the literature in the Library, would be considered scholarly references. Using published research to support the viewpoint of nursing, especially in cases being made for change,…

Explain what is meant by “indicator” organisms when testing a water sample. What are the media used to determine the presence of the indicator organisms? What are the morphological and biochemical characteristics of these indicator organisms?Discuss the three major species of Staphylococcus. Explain why one of them is more pathogenic compared to the other two species. Which factor determines the pathogenesis of the organisms?

Did you confirm that this is necessary? 3. Why is it necessary to wear clean, protective clothing when caring for a patient? 4. Why should hair be kept clean and out of the way when caring for patients? 5. How can the number of microorganisms in the environment be controlled? 6. When and why is hand washing important in patient care? 7. How can those who care for patients avoid spreading microorganisms among them? Exercise 20.1 and 20.2 Questions 1. Differentiate the microscopic morphology of staphylococci and streptococci as seen by Gram stain. 2. What are the two types of staphylococcal coagulase? 3. What is protein A?

According to the Theory of Evolution, Natural Selection is the mechanism by which evolution occurs. Remember: evolution occurs at the level of the population. Individuals do not evolve, populations evolve.
The process of Natural selection is based on the following four postulates (listed in your textbook on page 288):
Postulate 1 – Individual members of a population differ from one another in many respects.
Postulate 2 – At least some of the differences among members of a population are due to characteristics that may be passed from parent to offspring. That is, they are heritable or genetic.
Postulate 3 – In each generation, some individuals in a population survive and reproduce successfully but others do not.
Postulate 4 – The fate of individuals is not determined by luck. Instead, an individual’s likelihood of survival and reproduction depends on its characteristics. Individuals with advantageous traits survive longest and leave the most offspring, a process known as Natural Selection.
Assignment: Choose ONE animal species. Your goal is to describe the way in which an evolutionary change might occur for a particular characteristic (trait) of that species as a result of natural selection. The characteristic could be something like coloration pattern, length of the limbs, or size of the teeth or beak, or any measurable trait that is inherited.
The organism you choose should be a real one but the evolutionary change you describe can be real or theoretical.
In your own words,
Explain how the change in this trait occurs in terms of the four postulates listed above and in the book. You will describe what the population starts out like at time zero and then what it will look like at a later time, as a result of natural selection.
Make sure to explain the process by which the changes occurred. What is the selective pressure? Explain why the change might confer more fitness to a particular environment?
Tips: Make sure to include the following in your…
