NSG 448 Exam 4 V3 | NSG 448 Evidence-
Based Project Capstone | Actual Q&A with
Rationale (NSG448 Exam 4) | Grand
Canyon University
1. When developing a clinical question using the PICOT format, which elements must be
clearly defined to ensure a focused search for evidence? (Select All That Apply)
A. Population of interest
B. Intervention or area of interest
C. Comparison intervention or group
D. Outcome of interest
E. Timeframe for the intervention
F. Financial cost of implementation
Correct Answer: A, B, C, D, E
Explanation: The PICOT acronym stands for Population, Intervention, Comparison,
Outcome, and Time. Each of these components is essential to narrow the scope of a clinical
inquiry and facilitate a targeted search of the literature. While financial cost is an
implementation factor, it is not a standard component of the PICOT clinical question
framework itself.
,2. According to Lewin’s Change Theory, what occurs during the ‘unfreezing’ stage of a clinical
project?
A. Developing new behaviors and values
B. Stabilizing the change into the new status quo
C. Identifying the need for change and preparing the group
D. Evaluating the final outcomes of the implementation
Correct Answer: C
Explanation: Unfreezing involves creating the motivation to change by identifying a
problem and helping others recognize that the current status quo is no longer effective.
This stage is critical for overcoming resistance before new processes are introduced. Once
the equilibrium is disturbed, the group becomes ready for the next phase of moving toward
the new practice.
3. Which level of evidence is considered the highest in the evidence hierarchy for clinical
decision-making?
A. Expert opinion and consensus reports
B. Systematic reviews or meta-analyses of all relevant RCTs
C. Single randomized controlled trials (RCTs)
D. Case-control and cohort studies
Correct Answer: B
, Explanation: Systematic reviews and meta-analyses occupy Level I at the top of the
evidence pyramid because they synthesize findings from multiple high-quality studies. This
provides a more robust and generalized conclusion than a single study could offer. Utilizing
Level I evidence minimizes bias and provides the strongest foundation for evidence-based
practice changes.
4. When evaluating the outcomes of an evidence-based practice project, which factor is most
important for determining clinical significance?
A. A p-value less than 0.05
B. The impact of the results on patient care and health outcomes
C. The size of the sample used in the study
D. The length of the references section in the final report
Correct Answer: B
Explanation: Clinical significance refers to the practical importance of the results for
patient care, regardless of statistical significance. While a p-value indicates that a result is
unlikely to have occurred by chance, it does not necessarily mean the change is meaningful
in a clinical setting. Therefore, the nurse must assess whether the intervention resulted in a
tangible improvement in patient safety, health, or satisfaction.
5. In implementation science, what is the primary purpose of a ‘Change Champion’ within a
healthcare organization?
A. To manage the budget for the nursing department
