Relias Quality Assurance and Improvement 2 — Questions and Answers
Question 1: Which statistical tool displays the frequency distribution of data to identify variation patterns in a process?
- Control chart
- Histogram (Correct answer)
- Pareto chart
- Scatter diagram
Correct answer: Histogram
A histogram displays the frequency of data points across intervals, revealing the distribution and variation patterns within a process.
Question 2: In quality improvement, a 'fishbone diagram' is primarily used to:
- Track defect rates over time
- Identify root causes of a problem (Correct answer)
- Prioritize improvement initiatives by cost
- Monitor patient satisfaction scores
Correct answer: Identify root causes of a problem
A fishbone (Ishikawa) diagram organizes potential causes of a problem into categories to identify root causes systematically.
Question 3: A healthcare organization wants to reduce medication errors. Which PDSA cycle step involves testing the change on a small scale?
- Plan
- Do (Correct answer)
- Study
- Act
Correct answer: Do
The 'Do' step of the PDSA cycle is where the planned change is implemented and tested on a small scale.
Question 4: Benchmarking in quality improvement involves:
- Setting internal performance targets without external reference
- Comparing your processes to industry best practices (Correct answer)
- Auditing staff compliance with policies
- Measuring patient outcomes monthly
Correct answer: Comparing your processes to industry best practices
Benchmarking compares an organization's performance metrics and processes against recognized best practices or top-performing peers.
Question 5: Which term describes the degree to which health services increase the likelihood of desired health outcomes and are consistent with current professional knowledge?
- Efficiency
- Equity
- Effectiveness (Correct answer)
- Patient-centeredness
Correct answer: Effectiveness
Effectiveness refers to how well care produces desired outcomes based on current evidence and professional knowledge.
Question 6: A quality improvement team discovers that 20% of their processes cause 80% of their errors. This observation aligns with which principle?
- The bell curve principle
- The Pareto principle (Correct answer)
- The normal distribution rule
- The Six Sigma threshold
Correct answer: The Pareto principle
The Pareto principle (80/20 rule) states that roughly 80% of effects come from 20% of causes.
Question 7: In healthcare quality, 'sentinel event' review is conducted to:
- Reward high-performing staff
- Understand system failures after a serious adverse event (Correct answer)
- Establish annual performance benchmarks
- Determine patient satisfaction scores
Correct answer: Understand system failures after a serious adverse event
Sentinel event reviews analyze serious, unexpected adverse events to identify system failures and prevent recurrence.
