N4325 Nursing Research UT Arlington Knowledge Check #2 Test A nursing student is critiquing a study for her nursing research class. She feels like the study findings are generalizable to other ... settings and populations because: the sampling criteria for subjects was very narrow and restrictive, to provide a homogenous sample. the review of literature was extensive and included a conceptual framework. there is consistency of the current study's finding with that found in previous research studies. it has a small sample size which was obtained by convenience. In the Iowa Model of Evidence Based Practice, if a nurse brings forward a new research article with ideas that she/he would like to consider implementing on the unit, this would be considered to be: an opportunity to monitor and analyze structure, processes, and outcome data. a problem-focused trigger. an opportunity for comparative evaluation between two units. a knowledge-focused trigger. What statistical test would you use to determine a relationship between hours worked by nurses in a week and medication errors? X2- chi squared r- Pearson product moment frequency distribution standard deviation A power analysis is conducted to: test for internal validity. set the level of significance. determine a reliability coefficient. estimate a sample size. According to Makic et al (2014) what is the best way to confirm placement of a feeding tube when radiography is not available in a pediatric population? detecting carbon dioxide using colometry or capnography testing aspirate for pH and color testing aspirate for concentration of pepsin testing aspirate for presence of bilirubin and trypsin One of the 2020 goals of the Institute of Medicine (IOM) is that of all cli nical decisions be evidence-based. 70% 80% 60% 90% According to Peterson et al (2014), in AACN's 2012 rating scale level system, grouping together A, B, and C levels of evidence would result in experimental levels of evidence for practice. non-experimental levels of evidence for practice. evidence-based recommendations for practice. expert opinion or manufacturer's recommendations for practice. Content validity is defined as: maintaining research controls as indicated in the study design and hypotheses. measuring stability, equivalence, and homogeneity of a questionnaire. including all of the major elements relevant to the construct being measured. reviewing the inferential and demographics data of the sample. In this example of a PICO question: “In elderly hospitalized patients, what is the effect of hourly nursing rounds on reducing falls compared with the standard practice of bedside call lights and low bed positioning?” Hourly nursing rounds represent what element of the PICO format? I – intervention P- population C – comparison O - outcome The level of significance usually set in nursing studies is at either: 005 or .001 03 or .003 0.5 or 0.1 05 or .01 Which type of reliability is the consistency of measurement of two or more raters? Accuracy Test-retest Content Interrater According to Melnyk et al (2012), what specifically is the role of the EBP mentor? to work with staff nurses to consistently implement and sustain EBP to remove the barriers of EBP for staff nurses and nurse leaders to create clearinghouses of evidence-based practice information to work with potential obstacles to EBP such as physicians and nurse leaders Descriptive statistics should be reported in every study for which of the following reasons? As an indication of reliability To show the sample characteristics To provide a powerful analysis of data To determine validity Identify the type of sampling method used in the following example: To obtain mothers of children with cystic fibrosis, a researcher contacted one such mother who lived in her neighborhood and asked her if she knew any other mothers of children with cystic fibrosis. Cluster sampling Simple random sampling Convenience sampling Network sampling According to Groves, Gray and Burns (2015), which one of the following are considered barriers to evidence-based practice? There may be inadequate research evidence to support certain nursing interventions in practice. There are adequate resources for implementation of the Evidence Based Practice by nurses. The potential for improved outcomes for patients, providers, and healthcare agencies. There is a need to implement a pilot study as a part of following the Iowa model. According to Makic et al (2014), which one of these is NOT an intervention suggested for critically ill patients and frequent turning and the prevention of skin breakdown? providing good skin care practices and nutritional support ensuring the provision of adequate staff and a turning schedule for each unit turning patients every two hours (or more frequently) using of support surfaces therapies (specialty beds) for high risk patients Open-ended questions provide primarily data. qualitative exhaustive confirmatory quantitative A researcher notes that although no statistical significance was found, some elderly nursing home residents with dementia who were exposed to soothing music for 6 hours daily exhibited lower heart rates and less agitation. This finding would have which type of significance? General inferences Statistical significance Inferential statistics Clinical importance According to Peterson et al (2014), what type of evidence is considered to be the strongest? Similar findings from individual replicated studies. Meta-synthesis of related qualitative studies. Findings from non-experimental research. Systematic reviews of Random Controlled Trials (RCTs). According to Makic et al (2014), which of these is NOT a role of the nurse in the prevention of venothromboembolism (VTE)? Knowing the pharmacological recommendations for VTE prophylaxis for medical and surgical patients. Ensuring that chemical and mechanical therapies are maintained to reduce the risk of VTE. Assessing all patients on admission for risk factors related to the development of VTE. Providing early mobility / exercise for patient as indicated to reduce the risk of VTE. Which of the following measures of central tendency would be appropriate to describe the average pulse rates of a group of hospitalized patients? Range Median Variance Mean Cronbach’s alpha is used to determine: equivalence of observations. triangulation of theories. stability of repeated measurement over time. internal consistency among items on a scale. A sample of 75 subjects was asked by a nurse researcher to participate in a study at an immunization booth in the mall. What type of sampling method is the researcher using? Stratified random sampling Convenience sampling Network sampling Systematic sampling Which of the following types of studies would require the largest sample size? Correlational Grounded theory Ethnography Phenomenological [Show More]
