NR-503 Epidemiology Latest Edition Mandatory Revision Questions and Verified Answers 2024

Cultural Awareness - :Self-examination of one's own prejudices and biases toward other cultures. An in-depth exploration of one's own cultural/ethnic background. Cultural competence in nursing consists of four principles. - Care is designed for the specific client. Care is based on the uniqueness of the person's culture and includes cultural norms and values. Care includes self-employment strategies to facilitate client decision making to improve health behaviors. Care is provided with sensitivity and is based on the cultural uniqueness of clients. The APN may also use the Kleinman Explanatory Model of Illness (1978). Below are the questions that can be utilized. - What do you call your problem? What do you think caused your problem? Why do you think it started when it did? What does your sickness do to you? What do you fear most about your sickness? What are the chief problems your sickness has caused you? What kind of treatment do you think you should receive? What is the most important result you hope to receive from the treatment? According to Giger and Davidhizer (2000), although cultures differ, they all have the same basic organizing factors that must be assessed in order to provide care for culturally diverse patients. These factors include - communication (verbal and nonverbal); personal space; social organization; time perception; environmental control; and biological variations. The NCCC uses four major approaches to fulfill its mission, including - Web-based technical assistance, (2) knowledge development and dissemination, (3) supporting a community of learners, and (4) collaboration and partnerships with diverse groups. Epidemiological Triad: - host, agent, environment Genetics - The study of individual genes and their impact on relatively rare single gene disorders Absolute risk - is the probability of an event, such as illness, injury, or death. Gives no indication of how its magnitude compares with others The odds ratio - closely approximates the relative risk if the disease is rare. Odds ratio and the relative risk are used - to assess the strength of association between risk factor and outcome. How is Attributible risk used - is used to make risk-based decisions for individuals. Population-attributable risk measures - are used to form public health decisions EGAPP: - Evaluation of Genomic Applications in Practice and Prevention GAPPNet - Genomic Applications in Practice and Prevention Network (established in 2009) is a collaborative initiative involving partners from across the public health sector working together to realize the promise of genomics in health care and disease prevention. GEDDI - Genetics Early Disease Detection Intervention project (GEDDI) (established in 2009) developed a model strategy for using clinical, genetic, and family history information to reduce the risk of disease, death, and disability in affected individuals, family members, and populations. HuGENet - Human Genome Epidemiology Network (HuGENet) (established in 1998) helps translate genetic research findings into opportunities for preventive medicines and public health by advancing the synthesis, interpretation, and dissemination of populationbased data on human genetic variation in health and disease. HuGENet reviews are systematic, peer-reviewed synopses of the epidemiologic aspects of human genes, including prevalence of allelic variants in different populations, population-based information on disease risk, evidence for gene-environment interaction and quantitative data on genetic tests and services carried out according to specific guidelines. NHANES III - DC's Office of Public Health Genomics (established in 2002) formed a multidisciplinary working group with members from across CDC. It developed a proposal to measure the prevalence of selected genetic variants of public health significance in a representative sample of the U.S. population and to examine the association between the selected genetic variants and disease outcomes available in NHANES III data. The World Health Organization defines a pandemic - as a global epidemic that spreads to more than one continent (WHO, 2009). One of the more recent pandemics that you might be familiar with is the H1N1 influenza outbreak of 2009. Outbreak - the occurrence of disease within persons in excess of what would normally be expected in a clearly defined community, location, or time of year. An outbreak may only last for a matter of days or weeks, but may last for years Quarantine - the separation and restriction of the movement of people who were or are exposed to a contagious disease for a set period of time, to see whether they become ill Antigenic drift - is a term describing the changes that occur within virus's ribonucleic acid that changes the virus. Typically, these changes create seasonal changes or new strains of a virus WHO Pandemic Phases - Phase 1—None of the current viruses circulating in animals have been reported to cause infection in humans. Phase 2—An animal-based influenza virus is known to have caused infection in humans and is considered a potential pandemic threat.
