RNSG 1517 Evidence-Based Practice Exam 1 Study Guide
2026 | Complete Review | Graded A+
1. Describe what is meant by nursing-sensitive outcomes and provide an
example.
Nursing-sensitive outcomes are outcomes that can only be measured
in surgical settings.
Nursing-sensitive outcomes are only related to medication
administration.
Nursing-sensitive outcomes are patient outcomes that are directly
influenced by nursing care, such as pressure ulcers.
Nursing-sensitive outcomes are unrelated to nursing care and include
lab results.
2. Describe how quality improvement initiatives can impact nursing practice.
Quality improvement initiatives do not affect patient care.
Quality improvement initiatives lead to better patient outcomes and
more efficient nursing practices.
Quality improvement initiatives focus solely on reducing costs.
Quality improvement initiatives are only relevant to administrative staff.
3. What is the primary purpose of a meta-analysis in research?
To summarize a single study's findings
To analyze qualitative data only
To conduct a single study
To combine results from multiple studies
,4. What must be identified and controlled to avoid threats to validity in
research?
Research design
Confounding variables
Sample size
Data collection methods
5. Describe how control in quantitative research contributes to the validity of
study findings.
Control reduces the time required for data collection.
Control helps eliminate confounding variables, ensuring that the
results are due to the independent variable.
Control increases the sample size, which enhances the reliability of
the study.
Control allows researchers to manipulate the dependent variable
freely.
6. What is the primary responsibility of an investigator in a correlational study?
To develop new nursing theories.
To provide direct patient care during the study.
To conduct experiments to establish causation.
To identify and analyze relationships between variables.
7. Describe the importance of evidence-based practice in nursing.
Evidence-based practice is crucial in nursing as it integrates clinical
expertise with the best available research and patient values to
, improve patient outcomes.
Evidence-based practice focuses solely on patient values without
considering clinical expertise.
Evidence-based practice emphasizes the use of traditional methods
over new research findings.
Evidence-based practice is only relevant in research settings, not in
clinical practice.
8. What is the dependent variable in the study on the effect of smoking (i.e.
smokers vs non-smokers) on the blood pressure in males over 60 years of
age?
gender
age
tobacco use
blood pressure
9. Describe how systematic reviews contribute to evidence-based practice in
nursing.
Systematic reviews are not relevant to nursing practice.
Systematic reviews compile and analyze multiple studies to inform
best practices and improve patient care.
Systematic reviews only focus on qualitative research.
Systematic reviews are based solely on expert opinions.
, 10. In a nursing study aimed at improving patient outcomes, if a researcher
wants to evaluate the effectiveness of a new pain management protocol by
measuring patient pain levels before and after implementation, which
research design should they choose?
Quasi-experimental design
Longitudinal study
Randomized controlled trial
Descriptive study
11. Describe how quasi-experimental studies differ from randomized controlled
trials in terms of evidence strength.
Quasi-experimental studies provide low strength of evidence due to
lack of control.
Quasi-experimental studies are stronger than randomized controlled
trials.
Quasi-experimental studies provide moderate strength of evidence
compared to randomized controlled trials, which offer high
strength due to randomization.
Quasi-experimental studies provide the same strength of evidence as
randomized controlled trials.
12. Describe the importance of random selection in research studies.
Random selection is used to speed up the research process.
Random selection helps to eliminate bias and ensures that the
sample is representative of the population.
Random selection is only necessary for qualitative studies.
