NUR 4165 – Nursing Research & Evidence-Based
Practice Final Exam | 2025/2026
Focus Area 1: Research Design and Methodology (Qualitative, Quantitative, Mixed Methods) –
Questions 1-12
Question 1: In designing a study to explore the lived experiences of nurses implementing telehealth
during the post-pandemic era, which research design best aligns with phenomenological principles to
capture essence and meaning?
A. Experimental design with randomized controls
B. Phenomenological qualitative design
C. Cohort quantitative design
D. Grounded theory with constant comparison
Rationale: Phenomenological qualitative design is ideal for exploring subjective lived experiences and
essences, as per van Manen's hermeneutic approach (updated in 2025 qualitative synthesis guidelines by
the Qualitative Research in Nursing Journal). Options A and C are quantitative, focusing on causality or
incidence, while D emphasizes theory generation through iterative coding, not essence capture. This
design supports EBP by informing empathetic telehealth protocols.
Question 2: A nurse researcher aims to test the efficacy of a mindfulness intervention on burnout rates
among ICU staff using pre- and post-test scores. Which quantitative design provides the strongest causal
inference while minimizing bias?
A. Descriptive correlational
B. Randomized controlled trial (RCT)
C. Case-control
D. Cross-sectional survey
Rationale: RCTs offer the highest level of evidence (Level I per Melnyk & Fineout-Overholt's 2025 EBP
hierarchy) for causal relationships by randomizing participants and controlling variables, directly
applicable to intervention efficacy. A measures associations without manipulation, C is retrospective for
risk factors, and D captures snapshots without temporality, limiting causal claims.
Question 3: When integrating patient narratives with statistical outcomes in a study on palliative care
satisfaction, which mixed-methods design prioritizes qualitative depth while using quantitative data for
triangulation?
A. Convergent parallel
B. Explanatory sequential
C. Embedded quantitative
D. Multiphase exploratory
,Rationale: Explanatory sequential design collects quantitative data first for breadth, followed by
qualitative to explain anomalies, enhancing validity through triangulation (Creswell & Plano Clark, 2023,
with 2025 mixed-methods updates in Nursing Research). A merges simultaneously, C embeds one within
the other, and D spans phases without sequential explanation focus.
Question 4: A study examining cultural influences on pain management adherence employs ethnography.
What is the primary strength of this qualitative methodology in EBP translation?
A. Generalizability to large populations
B. Contextual understanding of cultural norms
C. Precise measurement of variables
D. Rapid data collection timelines
Rationale: Ethnography excels in immersing in cultural contexts to uncover behaviors and meanings,
informing culturally congruent EBP per ANA's 2025 cultural humility standards. A is quantitative
strength, C suits experimental designs, and D is impractical for fieldwork-intensive methods.
Question 5: In a quasi-experimental design evaluating a nurse-led fall prevention program, the absence of
randomization introduces which threat to internal validity?
A. Attrition bias
B. Selection bias
C. Maturation effect
D. Instrumentation error
Rationale: Selection bias arises from non-random group assignment, potentially confounding baseline
differences (Polit & Beck, 2025 Nursing Research text). While C and D are threats, and A relates to
dropout, selection is primary in quasi-experiments, guiding EBP implementation adjustments for equity.
Question 6: Grounded theory is selected for a study on decision-making in ethical dilemmas among
APRNs. What core process ensures theory emergence from data?
A. Hypothesis testing
B. Constant comparative analysis
C. Thematic content analysis
D. Statistical hypothesis testing
Rationale: Constant comparative analysis iteratively codes and compares data to build theory inductively
(Glaser & Strauss, 1967; reaffirmed in 2025 qualitative standards by International Journal of Qualitative
Methods). A and D are deductive quantitative, C is descriptive without theory-building focus.
Question 7: For a longitudinal quantitative study tracking hypertension management adherence over 5
years, which design element best controls for confounding variables?
A. Convenience sampling
B. Multivariate regression analysis
C. Snowball recruitment
, D. Single time-point data collection
Rationale: Multivariate regression adjusts for multiple confounders simultaneously, strengthening causal
inferences in longitudinal designs (per 2025 APA statistical guidelines integrated into nursing research). A
and C are sampling weaknesses, D negates longitudinal tracking.
Question 8: In mixed-methods research on opioid stewardship, an embedded design places qualitative
interviews within a quantitative survey. What is the rationale for this approach?
A. To prioritize quantitative dominance
B. To enrich quantitative findings with contextual insights
C. To conduct parallel independent analyses
D. To generate hypotheses post-quantitative phase
Rationale: Embedded designs nest qualitative to explain or illustrate quantitative results, enhancing
comprehensiveness (Fetters et al., 2024 mixed-methods framework, 2025 updates). A reverses priority, C
describes convergent, D fits sequential.
Question 9: A descriptive qualitative study using narrative inquiry to document patient stories in chronic
illness self-management. Which data saturation criterion indicates study completion?
A. Reaching a predetermined sample size
B. No new themes emerging from additional data
C. Achieving statistical significance
D. Covering all demographic strata
Rationale: Saturation in qualitative research occurs when new data yield no novel insights, ensuring
thematic depth (Saunders et al., 2018; 2025 RNAO qualitative guidelines). A is quantitative, C irrelevant,
D relates to diversity but not saturation.
Question 10: Comparing RCT and non-RCT designs in EBP for wound care protocols, which factor most
influences the choice of a pragmatic RCT?
A. Strict exclusion criteria
B. Real-world applicability and generalizability
C. Laboratory-controlled settings
D. Short-term outcome measurement
Rationale: Pragmatic RCTs prioritize external validity in clinical settings, bridging research-practice gaps
per NIH's 2025 dissemination standards. A and C favor explanatory RCTs, D limits long-term EBP
insights.
Question 11: In a convergent mixed-methods study on nurse resilience, merging datasets reveals
discrepancies. How should the researcher proceed to enhance validity?
A. Discard qualitative data
B. Conduct meta-inferences integrating convergences and divergences
