NUR 257 Nursing Research & Evidence-
Based Practice Final Exam Study Guide –
Complete Exam Material
Introduction:
This document covers key concepts for the NUR 257 final exam,
including nursing research principles, evidence-based practice
(EBP), epidemiology, ethics, and qualitative and quantitative
methodologies. It also includes clinical topics such as fall risk,
prevention strategies, elder abuse, disaster management, and
infection control.
The material is structured in a question-and-answer format, making
it useful for active recall and exam preparation. It provides a
comprehensive review aligned with core nursing concepts and
practical applications.
Exam Questions and Answers:
Participatory action research (ideology guided) ---Correct precise
answer----research that engages members of oppressed and
vulnerable communities in defining, investigating, analyzing, and
interpreting data about issues and problems relating to an
imbalance of power
-aim is to raise consciousness and empower groups to take action
toward change
,Guiding principle for qualitative sampling is not power analysis but
---Correct precise answer---data saturation (the point at which no
new information is obtained)
Triangulation ---Correct precise answer---use of more than one
method or data source
Analysis and interpretation of qualitative studies ---Correct precise
answer----categorizing (into broad categories)
-coding (individual pieces of data be category)
-identifying themes and patterns that accurately describe the
phenomenon
Aim for trustworthiness in qualitative research by ---Correct
precise answer----credibility (extent to which consumers of the
research can have confidence in the data and interpretations)
-dependability (extent to which the data are reliable over time and
conditions)
-confirmability (extent to which there would be agreement between
2 or more people about data's accuracy, relevance, or meaning)
-transferability (similar to generalizability)
-authenticity (extent to which the researchers faithfully report a
range of realities (thick description)
,Type 1 errors ---Correct precise answer---the null hypothesis is
wrongly rejected (false positive; there was no relationship between
the IV or DV)
Type 2 errors ---Correct precise answer---the null hypothesis is
wrongly accepted (false negative; in fact there was a relationship
between the IV and DV)
Potential bias in interpretation ---Correct precise answer----
researcher preconceptions
-causality instead of correlation
-unacknowledged limitations
Research utilization ---Correct precise answer----a movement in
healthcare that was a predecessor to EBP
EBP ---Correct precise answer---purpose driven
-to improve quality of care and patient safety by striving to deliver
care that is based on the best available research evidence
integrated with other pertinent factors (client preferences,
clinician expertise and experience, local context)
, Step 1 of EBP Process: formulate a clinical question ---Correct
precise answer----clinical questions arise from clinical problems
-Background vs Foreground
-typically focus on high-priority issues
PS format of clinical question ---Correct precise answer---
population and situation
PIO formation of clinical question ---Correct precise answer---
Population, intervention, outcomes
PICO(T) format of clinical question ---Correct precise answer---
population, intervention, comparison, outcomes, time frame
Step 2 of the EBP process: search for evidence ---Correct precise
answer---your clinical question guides your search; database
selection, use of keywords and subject headings
Why should you have your elderly patients bring in all medications
that they take? (OTC, herbal, etc.) ---Correct precise answer---To
