Relias Quality Assurance and Improvement 3 — Questions and Answers
Question 1: Which data collection tool is best suited for tracking how often different types of defects occur during an observation period?
- Run chart
- Check sheet (Correct answer)
- Control chart
- Affinity diagram
Correct answer: Check sheet
A check sheet is a structured form for collecting and tallying the frequency of different types of defects or events.
Question 2: When a process is 'in control' on a control chart, it means:
- The process meets all customer requirements
- Variation is caused only by common causes (Correct answer)
- No defects are being produced
- The process exceeds Six Sigma standards
Correct answer: Variation is caused only by common causes
A process 'in control' exhibits only common-cause variation, meaning all data points fall within control limits without special-cause signals.
Question 3: Which quality improvement model uses 'Define, Measure, Analyze, Improve, Control' phases?
- PDSA
- LEAN
- Six Sigma DMAIC (Correct answer)
- ISO 9001
Correct answer: Six Sigma DMAIC
Six Sigma's DMAIC framework structures improvement projects through five sequential phases: Define, Measure, Analyze, Improve, and Control.
Question 4: A nurse manager wants to display the relationship between patient acuity scores and medication errors. Which tool is most appropriate?
- Pie chart
- Scatter diagram (Correct answer)
- Histogram
- Flowchart
Correct answer: Scatter diagram
A scatter diagram plots two variables on X and Y axes to visualize and analyze possible correlations between them.
Question 5: In Lean methodology, 'muda' refers to:
- Continuous improvement activities
- Waste that adds no value to the process (Correct answer)
- Standard operating procedures
- Patient satisfaction metrics
Correct answer: Waste that adds no value to the process
Muda is a Japanese term for waste — any activity that consumes resources without adding value from the customer's perspective.
Question 6: Which of the following best describes a 'process measure' in quality improvement?
- The final health outcome experienced by the patient
- Whether a specific step in care was delivered correctly (Correct answer)
- Patient perception of the care environment
- The cost per patient encounter
Correct answer: Whether a specific step in care was delivered correctly
A process measure assesses whether a specific, evidence-based step in care delivery was performed as intended.
Question 7: Which accreditation body requires healthcare organizations to implement ongoing performance improvement activities?
- OSHA

- HIPAA
- CMS only
Correct answer: The Joint Commission
