Question 1 4 pts Question 2 4 pts Question 3 4 pts Question 4 4 pts Question 5 4 pts 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 clinical decisions be evidence-based. 70?`??cording 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 Question 6 4 pts Question 7 4 pts Question 8 4 pts Question 9 4 pts Question 10 4 pts 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
