NR 503 Midterm Exam Study Guide: Chamberlain College of Nursing WEEK 1,2AND 3 • How does social justice and health inequities influence population health care provision? Why is this critical information for the provision of evidence-based care? Population-based nursing is the provision of evidence-based care to targeted groups of people with similar needs in order to improve health, or stated otherwise, to improve health. In order to provide this care providers must consider health inequities and social justice in order to improve health care for all people. Population health is typically interested in high risk aggregates(subpopulations) which means looking at those health inequities and using social justice theory to integrate health promotion and disease prevention interventions for those high risk aggregates. • Review terminology Week 2 1. Is screening a tertiary intervention? If yes, why, if not, what is it? No. Screening are a secondary intervention. Tertiary interventions focus on alleviating disability and are strategies done in middle or late stages of diseases. An example of a tertiary intervention would be cardiac rehab or physical therapy after a hip replacement 2. How does a provider determine the usefulness, appropriateness, of a screening test? Where would a NP look to find a screening test? What determines if a screening test should be used? The target population needs to be identifiable and accessible and the disease should affect a sufficient number of people. The screening test should be sensitive enough to detect most cases and be specific enough to limit the number of false positives. Screening tests should be relatively inexpensive, easy to administer, and have minimal side effects. The validity of the screening test is the ability to accurately identify those that have the disease. Determining if a screening test should be used can be evaluated by the success of a screening tool. Does the screening tool do what it was intended to do and reduce overall mortality, decrease case fatality, increase early detection, reduce complications or increase quality of life? APNs can look for screening test through the U.S Preventative Services Task 3. Can you explain what “descriptive epidemiology” means? What is the purpose? How is it used? Concerned with characterizing the amount and distribution of health and disease within a population. Through the process of looking at rates, incidence, prevalence, mortality, survival, and prognosis we have and understanding of a disease and knowledge of how illnesses and diseases are distributed, what populations are impacted, and how populations differ. Also what interventions would be best for who. 1. Objectives of epidemiology.2-7 Step 1. Understanding the etiology or cause of a disease (risk factors) Step 2. Finding out the extent that a disease or health problem affects a community or population. Step 3. Determine the natural history or prognosis Step 4. Evaluate existing and newly developed preventative therapeutic measures and modes of healthcare delive
