NURS 4100 WEEK 9 QUIZ: QUALITY
AND SAFETY THROUGH EVIDENCE
BASED PRACTICE
1. Which of the following best distinguishes Quality Improvement (QI) from Evidence-Based
Practice (EBP)?
A. EBP involves the systematic application of best research evidence to clinical decision-
making.
B. QI focuses on generating new knowledge through rigorous scientific testing.
C. QI is primarily concerned with ethical approval from the Institutional Review Board
(IRB).
D. EBP focuses exclusively on local process improvements within a specific unit.
Answer: A
Conceptual Explanation: EBP is the integration of clinical expertise, patient values, and
the best research evidence into the decision-making process for patient care, whereas QI is
a continuous process that monitors and improves the quality of care in a specific setting.
,2. In the PDSA cycle of quality improvement, what does the ‘Study’ phase primarily involve?
A. Implementing the plan on a small scale to test the change.
B. Analyzing the data collected to compare results against predictions.
C. Defining the objectives and predicting what will happen.
D. Standardizing the change across the entire organization.
Answer: B
Conceptual Explanation: The ‘Study’ phase involves analyzing the data to determine if the
change resulted in an improvement and comparing the results to the initial predictions
made in the ‘Plan’ phase.
3. Which tool is most effective for identifying the multiple root causes of a specific patient
safety event?
A. Pareto Chart
B. Scatter Plot
C. Control Chart
D. Fishbone (Ishikawa) Diagram
Answer: D
Conceptual Explanation: A Fishbone diagram is a visualization tool for categorizing the
potential causes of a problem in order to identify its root causes, often grouping them by
categories like People, Methods, and Equipment.
, 4. What is the primary goal of a Root Cause Analysis (RCA) after a sentinel event?
A. To identify system-level failures and prevent recurrence.
B. To discipline staff members who deviated from standard protocols.
C. To identify which healthcare provider is legally liable for the error.
D. To provide data for the hospital’s marketing and public relations team.
Answer: A
Conceptual Explanation: RCA is a reactive process used to identify underlying system
failures that contributed to an error, focusing on how the system can be improved to
prevent similar future events rather than individual blame.
5. A nurse manager is comparing the unit’s fall rate to national standards. This process is
known as:
A. Benchmarking
B. Risk Adjustment
C. Gap Analysis
D. Outcome Auditing
Answer: A
Conceptual Explanation: Benchmarking is the process of comparing one’s business
processes and performance metrics to industry bests and best practices from other
companies or national standards.
