MODULE 1: EVIDENCE-BASED PRACTICE AND NURSING RESEARCH
1. • A nurse is developing a clinical question to guide an evidence-based practice change. Which
component of the PICOT format addresses the intervention or area of interest?
•• B) Intervention
Rationale: In the PICOT format, "I" stands for Intervention—the treatment, exposure, or area of
interest being studied. P = Population, C = Comparison, O = Outcome, T = Time.
,2. • A nursing researcher is evaluating the strength of evidence from various study designs.
Which type of study provides the highest level of evidence for determining the effectiveness of
an intervention?
•• D) Systematic review of randomized controlled trials
Rationale: Systematic reviews and meta-analyses of RCTs represent the highest level of
evidence in the evidence hierarchy, providing the most reliable evidence for practice decisions.
3. • A nurse is appraising a research article and notes that the study used a convenience sample
of 30 participants. Which limitation is most associated with this sampling method?
•• C) Limited generalizability of findings
Rationale: Convenience sampling involves selecting participants who are readily available,
which increases the risk of sampling bias and limits the generalizability of findings to the
broader population.
4. • A nurse researcher is analyzing data and calculating the average score of a group. Which
measure of central tendency is most appropriate for normally distributed continuous data?
•• A) Mean
Rationale: The mean is the arithmetic average and is most appropriate for normally distributed
continuous data. The median is preferred for skewed distributions, and the mode is used for
categorical data.
5. • Which statement best describes the purpose of critical appraisal of literature in evidence-
based practice?
•• B) To identify strengths, weaknesses, quality, and credibility of studies
Rationale: Critical appraisal is performed to evaluate the quality, credibility, and meaning of
studies by identifying strengths and weaknesses in the research.
6. • A nurse is implementing the Iowa Model of Evidence-Based Practice. Which is the first step
in this model?
, •• D) Identify a clinical problem or knowledge trigger
Rationale: The Iowa Model begins with identifying a clinical problem or knowledge trigger that
prompts the need for practice change. This is followed by forming a team, searching for
evidence, and evaluating outcomes.
7. • A nursing study reports a Cronbach's alpha of 0.89. This indicates:
•• A) High internal consistency reliability
Rationale: Cronbach's alpha measures internal consistency reliability. Values above 0.70 are
considered acceptable, and values above 0.80 indicate good to excellent internal consistency.
8. • A nurse is reviewing literature for an EBP project. Which statement about using recent
literature is correct?
•• C) Literature from the last 5 years is generally considered current
Rationale: In evidence-based practice, literature published within the last 5 years is generally
considered current, though landmark or groundbreaking older studies may also be included.
9. • A researcher is conducting a study that examines the relationship between two variables
without manipulating either. This design is best described as:
•• C) Correlational study
Rationale: Correlational studies examine relationships between variables without manipulation.
Unlike experimental designs, correlational studies do not establish causation.
10. • A nurse is conducting a study that follows a group of participants over time to observe
outcomes. This design is called a:
•• B) Prospective cohort study
Rationale: A prospective cohort study follows participants forward in time to observe outcomes.
This design is valuable for studying risk factors and disease progression.
11. • A nurse is using the best available evidence, clinical expertise, and patient preferences to
make a clinical decision. This approach defines:
