CDM Quality Improvement and Performance Monitoring 2 — Questions and Answers
Question 1: A fishbone (Ishikawa) diagram is used in dietary quality improvement primarily to:
- Track inventory turnover rates
- Identify potential root causes of a problem (Correct answer)
- Schedule staff work assignments
- Plan a 4-week menu cycle
Correct answer: Identify potential root causes of a problem
A fishbone (cause-and-effect) diagram systematically maps out potential causes of a problem to support root cause identification.
Question 2: Which quality improvement methodology focuses specifically on eliminating waste and non-value-added steps in dietary operations?
- Total Quality Management (TQM)
- Six Sigma
- Lean methodology (Correct answer)
- Root Cause Analysis (RCA)
Correct answer: Lean methodology
Lean methodology is designed to identify and eliminate waste (non-value-added activities) and streamline process efficiency.
Question 3: A run chart in dietary quality improvement is used to:
- Assign tasks to dietary staff for each shift
- Display performance data over time to reveal trends or patterns (Correct answer)
- Plan the most efficient meal delivery routes
- Log food holding temperatures by item
Correct answer: Display performance data over time to reveal trends or patterns
A run chart plots sequential data points over time, making it easy to identify trends, cycles, or shifts in performance.
Question 4: When performing a root cause analysis (RCA) after a dietary error, the primary focus should be on:
- Identifying and disciplining the responsible employee
- Identifying system and process failures that allowed the error to occur (Correct answer)
- Documenting the error for potential legal defense
- Filing a report with the state health department
Correct answer: Identifying system and process failures that allowed the error to occur
RCA takes a systems approach, focusing on process and system failures rather than individual blame, to prevent recurrence.
Question 5: The '5 Whys' technique in quality improvement involves:
- Surveying five staff members about a problem
- Repeatedly asking 'why' to drill down to the root cause of a problem (Correct answer)
- Listing the five most likely solutions to a problem
- Conducting five separate inspections of a dietary process
Correct answer: Repeatedly asking 'why' to drill down to the root cause of a problem
The '5 Whys' technique uses repeated questioning ('why did this happen?') to progressively uncover the root cause of a problem.
Question 6: Which of the following best describes a 'sentinel event' in the context of a dietary department?
- An unexpected event causing serious harm, such as a severe allergic reaction from a food allergy error (Correct answer)
- A routine scheduled inspection by the state health department
- A planned special event menu for a holiday
- A scheduled competency evaluation for dietary aides
Correct answer: An unexpected event causing serious harm, such as a severe allergic reaction from a food allergy error
A sentinel event is an unexpected occurrence resulting in serious harm or death that requires immediate investigation and corrective action.
Question 7: In tracer methodology used by The Joint Commission, surveyors evaluate a dietary department by:
- Tracing the path of food from receiving dock to patient tray
- Following a patient's care experience through the facility to evaluate system performance (Correct answer)
- Monitoring the chemical tracer compounds used in sanitation verification
- Tracking the movement patterns of dietary staff during meal service
Correct answer: Following a patient's care experience through the facility to evaluate system performance
Tracer methodology follows an individual patient's care experience across departments to evaluate how systems and processes work together.
