WGU C431 question 100% correct answer 2022Because it applies scientific evidence from peer-reviewed clinical research. The U.S. Centers for Disease Control and Prevention has reported that hospital-acquired infections affect up to 1 in 25 patients, leading to significant patient morbidity and mortality. Why should evidence-based practice be applied to address this issue? Because it applies scientific evidence from peer-reviewed clinical research. Because it applies nonclinical therapy to promote delivery of quality of care. Because it uses research from nonmedical journals to promote quality care. Because it uses information systems to collect current timely data for analysis. It focuses on the delivery of patient-centered care. A skilled nursing facility administrator has noticed that patient satisfaction scores are low when compared to the national average. Why should evidence-based practice be used to improve these patient scores? It focuses on the delivery of patient-centered care. It uses a higher nurse-to-patient ratio to ensure 24-hour care. It uses newly approved pharmaceutical therapies to test efficacy. It focuses on the treatment of disease using the medical model. Evaluating participants' knowledge A clinical manager at a community health center has asked an intern to develop a pilot study on the effectiveness of two alternative approaches to breast cancer education. The intern wants to measure the knowledge women have about breast cancer before and after the distribution of a brochure or before and after a session with the physician. Which methodology will provide information about the effectiveness of one cancer education method over the other? Evaluating participants' knowledge Analyzing participants' medical records Surveying participants about the experience Videotaping participants reading the brochure Quantitative cohort study A researcher wanted to investigate the effects of fast food restaurant availability on the local adult obesity epidemic over a period of five years. The hypothesis is that in a specific zip code the number of fast food establishments is positively associated with the number of obese adults. All fast food locations in a certain zip code have been identified, and physicians have been contacted to provide each patient's de-identified age, gender, height, weight, and body mass index (BMI). Patients will be placed in groups according to their weight and height. Which type of research was conducted? Qualitative case study Qualitative cohort study Quantitative case study Quantitative cohort study Quantitative The vice president of nursing at a large hospital is reviewing patient satisfaction scores from a recent survey that asked a series of questions about how patients felt about the care received. Which type of survey methodology was utilized in this study? Qualitative Quantitative Experimental Mixed-methods Randomized control trial A pharmaceutical company is currently testing a new drug.

Case study Cohort study Case control study Randomized control trial Performing the search A chief of medicine is reviewing the current treatment protocol for simple pneumonia patients. New medications are available that might improve patient outcomes and reduce the inpatient stay. The chief of medicine asks an assistant to contact the pharmacist to research possible benefits for these new medications and the impact on the treatment protocol. Which evidence-based practice process step is demonstrated in this situation? Organizing findings Performing the search Identifying target resources Appraising trustworthiness Recognize the need for information Recent employee surveys at a local hospital have indicated that the nursing staff, particularly the staff on the third shift, has a much lower-than-average job satisfaction rating. Given the time and cost involved to hire and train replacement nurses, the vice president of nursing has contacted the vice president of human resources to discuss the situation. Which stage of the evidence-based process is this? Establish purpose Perform the search Formulate focused questions Recognize the need for information Agency for Healthcare Research and Quality A clinical manager of a hospital's tobacco cessation program is seeking new, effective clinical guidelines. Which source should the manager consult? Agency for Healthcare Research and Quality Centers for Medicaid and Medicare Services National Association of Health Data Organizations National Institute of Occupational Safety and Health Office of the National Coordinator for Health Information Technology The chief financial officer has asked an administrator to confirm the incentive payment schedule and amount for eligible professionals who adopt an electronic health record and can demonstrate its meaningful use. Which organization will provide this information? Office of the National Coordinator for Health Information Technology Centers for Medicare and Medicaid Services Department of Health and Human Services Centers for Disease Control and Prevention Case study A medical director needs to determine the treatment protocols appropriate to use for Ebola patients. The medical director finds a peer-reviewed article outlining a protocol. Which research approach provides the highest strength of evidence and should be used by this medical director? Case study Case-control study Cross-sectional survey Randomized controlled trial Case reports A doctor needs to develop clinical guidelines for a rare psychiatric disorder. Which evidence is appropriate for this situation? Case reports Systematic review Cross-sectional survey Randomized controlled trials Validity of study method Timeliness of information A hospital informatics analyst has been asked to review case studies for current treatment protocols for congestive heart failure. The analyst finds multiple studies in peer-reviewed journals, as well as other credible sources. The analyst summarizes several articles starting with articles with publication dates from 2008 through 2010. What are two likely issues with the case studies? Choose 2 answers Invalid sources Large sample size Validity of study method Timeliness of information The patient satisfaction scores for patient discharge instructions should be higher. A skilled nursing facility (SNF) receives a patient satisfaction score of 4.3 out of 5 for patient discharge instructions. The standard average patient satisfaction score is 4.2 out of 5 for SNFs in the market area while the national average is 4.9. Which problem can be determined from this information? The discharge instructions fail to meet the needs of the patient. The discharge instructions should be evaluated using a compliance measure. The patient satisfaction scores are incapable of assessing discharge instructions. The patient satisfaction scores for patient discharge instructions should be higher. Some healthcare workers may become sick and spread influenza to others in the hospital. A hospital administrator is reviewing an employee attendance report. It appears that 92% of the healthcare workers elected to receive the influenza vaccination. Which problem is presented by the data? Some healthcare workers may become sick and spread influenza to others in the hospital. The hospital needs to increase its malpractice insurance to cover the spread of infection. The majority of healthcare workers are refusing or are opting out of receiving the vaccination. The hospital does not have an adequate supply of influenza vaccinations dedicated for its staff. Data that show operating room usage variance status A hospital administrator using statistical models and evidence-based practice decided that efficiencies were needed to improve operating room utilization. Based on the current usage patterns the administrator closed one operating room on Sunday nights. Which type of statistical data would have helped the administrator come to this decision? Data that show operating room case mix index Data that show surgical discounted fees for service Data that show prospective and retrospective revenue Data that show operating room usage variance status It allows for quantification of nursing adherence to protocols. It allows for analysis of the research variable "staff satisfaction." A healthcare administrator is aware of the Institute of Medicine's report addressing root causes of negative patient outcomes. Two of the systemic problems identified in the report are staff working conditions and clinical processes. To address these concerns and make improvements, the administrator decided to implement evidence-based decision making practices using statistical data. What are two reasons this administrator used statistics to impact the decision making? Choose 2 answers It allows for quantification of nursing adherence to protocols. It allows for testing of means squares for clinician outcomes. It allows for factoring of the significance for patient satisfaction.
