NSG 448 Exam 1 V3 | NSG 448 Evidence-
Based Project Capstone | Actual Q&A with
Rationale (NSG448 Exam 1) | Grand
Canyon University
1. What is the primary purpose of using the PICOT format when developing a clinical
question?
A. To provide a structured framework that guides the literature search and project focus.
B. To identify the specific statistical tests required for data analysis.
C. To ensure that the research project receives funding from external agencies.
D. To define the roles of the various interprofessional team members.
Correct Answer: A
Explanation: The PICOT framework is designed to streamline the process of evidence-
based practice by identifying key components of a clinical issue. It helps the nurse
researcher refine a broad topic into a searchable and manageable question. Using this
structure ensures that all clinical outcomes and population characteristics are addressed
before the literature review begins.
2. In the PICOT acronym, what does the ‘C’ represent?
A. Clinical setting
B. Current practice
,C. Comparison intervention
D. Cost-benefit analysis
E. Case management
Correct Answer: C
Explanation: The ‘C’ in PICOT stands for Comparison intervention or group. This
component allows the clinician to evaluate the new intervention against the current
standard of care or an alternative treatment. It is vital for determining if a proposed change
provides superior results compared to what is currently being implemented.
3. Which of the following are considered ‘Vulnerable Populations’ in nursing research and
require additional ethical safeguards? (Select All That Apply)
A. Children and minors
B. Registered nurses in the clinical setting
C. Pregnant women and fetuses
D. Prisoners and incarcerated individuals
E. Cognitively impaired persons
F. University students with full capacity
Correct Answer: ACDE
Explanation: Vulnerable populations are groups that may be at risk of coercion or undue
influence during the research process. The Belmont Report and federal regulations
, mandate extra protections for children, prisoners, pregnant women, and those with
diminished mental capacity. Researchers must ensure that these individuals are not
exploited and that their rights are strictly upheld through specialized IRB review.
4. A nurse identifies that a systematic review of randomized controlled trials (RCTs) is
available on their clinical topic. According to the hierarchy of evidence, what level of evidence
does this represent?
A. Level III
B. Level II
C. Level I
D. Level IV
Correct Answer: C
Explanation: A systematic review or meta-analysis of all relevant RCTs is categorized as
Level I evidence, which is the highest level in the hierarchy. This type of evidence
synthesizes findings from multiple high-quality studies to provide the strongest basis for
clinical decision-making. Nurses should prioritize Level I evidence whenever it is available
to ensure the best patient outcomes.
5. Which statement best describes the difference between Evidence-Based Practice (EBP) and
Nursing Research?
A. EBP involves generating new knowledge, while research applies existing knowledge.
B. Research only occurs in academic settings, while EBP only occurs in hospitals.
