NURS 4100 WEEK 4 QUIZ: QUALITY
AND SAFETY THROUGH EVIDENCE
BASED PRACTICE
1. When formulating a PICO(T) question, what does the ‘T’ represent?
A. Timeframe for the outcome
B. Type of research design
C. Treatment administered
D. Target population
Answer: A
Conceptual Explanation: In the PICO(T) framework, T stands for the Timeframe, which
defines the period during which the intervention is expected to produce an outcome.
2. Which level of evidence is considered the ‘gold standard’ in the hierarchy of evidence for
clinical effectiveness?
A. Expert opinion and case reports
B. Systematic reviews of randomized controlled trials (RCTs)
C. Non-randomized controlled trials
,D. Single descriptive or qualitative studies
Answer: B
Conceptual Explanation: Systematic reviews and meta-analyses of RCTs are Level I
evidence, representing the highest quality of evidence for clinical effectiveness.
3. In the context of Quality Improvement (QI), what is the primary purpose of a Root Cause
Analysis (RCA)?
A. To assign blame to specific individuals involved in a sentinel event
B. To determine the cost-effectiveness of a new medical device
C. To identify the underlying systems and process failures leading to an error
D. To evaluate the clinical significance of a research study
Answer: C
Conceptual Explanation: RCA is a retrospective method used to identify the fundamental
systemic causes of errors rather than focusing on individual blame.
4. Which QSEN competency focuses on using data to monitor the outcomes of care processes
and improve healthcare systems?
A. Patient-Centered Care
B. Quality Improvement
C. Evidence-Based Practice
D. Informatics
, Answer: B
Conceptual Explanation: Quality Improvement involves using data to monitor outcomes
and design changes to improve the quality and safety of health care systems.
5. A p-value of 0.03 in a nursing research study indicates that:
A. The results are clinically significant but not statistically significant
B. The intervention failed to show a difference
C. There is a 3% chance that the results are due to random chance
D. The sample size was too small to draw conclusions
Answer: C
Conceptual Explanation: A p-value measures statistical significance; p < 0.05 generally
indicates that the probability the results occurred by chance is less than 5%.
6. Which model is commonly used to guide the implementation of evidence-based practice
changes within a clinical setting?
A. The Iowa Model of Evidence-Based Practice
B. Maslow’s Hierarchy of Needs
C. The Glasgow Coma Scale
D. The SWOT Analysis Framework
Answer: A
