SECTION 1: NURSING RESEARCH & EVIDENCE-BASED PRACTICE (EBP) Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A nurse manager on a medical-surgical unit notices an increase in hospital-acquired
pressure injuries over the past three months. She convenes a unit-based council to
review current turning protocols and compares them against the latest WOCN
guidelines. The council decides to pilot a new two-hour turning schedule with a dynamic
support surface on half the unit while maintaining standard care on the other half, then
measuring outcomes after 8 weeks. This approach best exemplifies which EBP
implementation model?
A. The Iowa Model of Evidence-Based Practice
B. The Ottawa Model of Research Use
C. The Stetler Model of Evidence-Based Practice
D. The Promoting Action on Research Implementation in Health Services (PARIHS)
framework ✓ CORRECT
,Correct Answer: D
Rationale: The PARIHS framework emphasizes the interplay between evidence, context,
and facilitation, which matches the nurse manager's real-world approach of adapting
guidelines to her specific unit context with a structured pilot and facilitator-led
implementation. The Iowa Model is more commonly used for clinical decision-making
around specific patient problems rather than unit-wide practice changes. In practice,
PARIHS helps teams recognize that even strong evidence fails without attention to
organizational culture and local leadership support.
Question 2 of 50
A DNP student is developing a clinical question about the effect of music therapy on
postoperative pain in older adults. She initially writes: "I want to know if music helps
older adults after surgery." Her faculty advisor asks her to restructure this into a
searchable, focused question using the PICO format. After revision, which PICO element
is most likely missing or vague in her original draft?
A. Comparison intervention
B. Patient population
C. Outcome of interest
D. Intervention specificity ✓ CORRECT
Correct Answer: D
Rationale: The original draft uses the vague term "music" rather than specifying the type,
duration, or delivery method of music therapy, making the intervention too broad for a
focused literature search. While "older adults" and "after surgery" loosely define
population and setting, the lack of intervention specificity is the primary weakness that
would yield unmanageable search results. In real EBP work, vague intervention
descriptions lead to heterogeneous study pools that are impossible to synthesize
meaningfully.
,Question 3 of 50
A hospital's nursing research council is reviewing a proposal to study the impact of a
new nurse residency program on retention rates. One council member argues that the
hospital should first conduct an integrative review to understand what is already known
before investing in primary data collection. Another member counters that a scoping
review would be more appropriate because the literature spans nursing education,
organizational psychology, and health economics. The council chair asks which review
type would best map the breadth of evidence across these disciplines without quality
appraisal of individual studies.
A. Integrative review
B. Scoping review ✓ CORRECT
C. Systematic review
D. Meta-analysis
Correct Answer: B
Rationale: A scoping review is designed to map the extent, range, and nature of research
activity across diverse disciplines and does not require quality appraisal of individual
studies, which aligns perfectly with the council's need to explore literature spanning
multiple fields. An integrative review synthesizes findings from various methodologies
but still involves critique and synthesis of study quality, making it more intensive than
needed at this exploratory stage. Scoping reviews are increasingly used in nursing to
determine whether sufficient primary literature exists to justify a full systematic review.
Question 4 of 50
A nurse researcher is planning a study on sleep quality in shift workers using the
Pittsburgh Sleep Quality Index (PSQI). During her literature review, she finds three
studies that used the PSQI with hospital nurses: one reported a Cronbach's alpha of
0.52, another reported 0.89, and a third reported 0.71. She needs to determine whether
, the instrument is appropriate for her target population of emergency department nurses
working 12-hour rotating shifts. What should be her primary consideration when
evaluating these conflicting reliability estimates?
A. The sample size of each prior study
B. The cultural and occupational context in which each study was conducted ✓
CORRECT
C. The publication date of each study
D. The statistical power of each prior study
Correct Answer: B
Rationale: Reliability is not a fixed property of an instrument but depends on the
population and context in which it is used, so the researcher should prioritize studies
conducted with shift-working nurses in high-stress clinical environments similar to her
own. A Cronbach's alpha of 0.52 in one study may reflect genuine heterogeneity in how
ED nurses experience sleep disturbance rather than instrument deficiency. In nursing
research, instruments validated with day-shift medical-surgical nurses often perform
differently when applied to specialty populations like emergency or critical care nurses.
Question 5 of 50
A quality improvement team is analyzing why a new fall prevention protocol has not
reduced fall rates despite strong evidence supporting its effectiveness. Through focus
groups, they discover that night-shift nurses find the hourly rounding documentation too
time-consuming and often complete it retrospectively at the end of the shift, making the
intervention unreliable. Which concept from implementation science best explains this
gap between evidence and outcomes?
A. Fidelity failure ✓ CORRECT
B. Type III error
C. Selection bias
D. Hawthorne effect
