Actual Q&A with Rationale (NSG324A
Exam 4) | Grand Canyon University
1. When a nurse researcher is preparing to disseminate the findings of an evidence-based
practice (EBP) project, which method is most effective for reaching a broad, international
audience of healthcare professionals?
A. Presenting a poster at a local hospital staff meeting.
B. Publishing the results in a peer-reviewed professional journal.
C. Discussing the results during an informal unit huddle.
D. Presenting the findings at a regional nursing workshop.
Correct Answer: B
Explanation: Publishing in a peer-reviewed journal ensures that the information is
accessible to a global audience of clinicians and researchers. Peer review provides an
additional layer of validation and quality control for the study’s findings. This method
remains the gold standard for formal dissemination in the academic and professional
nursing community.
,2. The Iowa Model of Evidence-Based Practice identifies several triggers for change in clinical
practice. Which of the following are considered knowledge-focused triggers? (Select All That
Apply)
A. New research or literature findings.
B. National clinical practice guidelines.
C. Data from quality improvement reports.
D. Philosophy of care within the organization.
E. Risk management data and trends.
F. New federal regulations or standards.
Correct Answer: A, B, D, F
Explanation: Knowledge-focused triggers arise from new information, such as research
findings, updated national guidelines, or changes in organizational philosophy. In contrast,
problem-focused triggers are derived from clinical data, such as infection rates or financial
reports. Identifying the type of trigger is a crucial first step in the Iowa Model to determine
the appropriate course of action.
3. In a quantitative study comparing two wound care treatments, the researcher reports a p-
value of 0.02. How should the nurse interpret this finding?
A. The result is statistically significant and unlikely to have occurred by chance.
B. There is a 2% chance that the treatment is effective.
, C. The result is not statistically significant and occurred by chance.
D. The treatment is clinically significant regardless of the statistics.
Correct Answer: A
Explanation: A p-value of 0.02 is less than the standard alpha level of 0.05, indicating
statistical significance. This means there is only a 2% probability that the observed
differences between the groups were due to random chance. Statistical significance is a
necessary component for determining if an intervention should be considered for
evidence-based implementation.
4. According to the hierarchy of evidence, which of the following represents the highest level
of evidence available for clinical decision-making?
A. A systematic review or meta-analysis of RCTs.
B. A single randomized controlled trial (RCT).
C. A well-designed cohort study.
D. Opinions of respected authorities or expert committees.
Correct Answer: A
Explanation: Systematic reviews and meta-analyses are at the top of the evidence
hierarchy because they synthesize the results of multiple high-quality studies. These
summaries provide a more comprehensive and reliable evidence base than any individual
study could offer. Utilizing Level 1 evidence reduces bias and increases the likelihood of
improved patient outcomes.
