Registered Dietitian Nutritionist Quality Control & Assurance 2 — Questions and Answers
Question 1: A hospital foodservice director notices that patient meal satisfaction scores have dropped over three consecutive months. Which quality improvement tool would BEST help identify the root cause?
- Run chart to track trends over time (Correct answer)
- Pie chart showing meal category distribution
- Histogram of caloric content per meal
- Bar chart comparing breakfast vs. dinner scores
Correct answer: Run chart to track trends over time
A run chart plots data over time and can reveal trends, shifts, or cycles that help identify when and why a problem began.
Question 2: In a clinical nutrition department, a newly implemented enteral feeding protocol is being evaluated. What does 'process measure' refer to in this context?
- Whether the protocol steps are being followed correctly (Correct answer)
- The 30-day patient mortality rate
- The cost savings achieved after implementation
- The number of patients discharged on tube feeding
Correct answer: Whether the protocol steps are being followed correctly
Process measures assess whether specific steps or actions in a protocol are being executed as intended, distinct from outcomes or structural measures.
Question 3: A dietitian is performing a chart audit and finds that 40% of nutrition assessments were not completed within the required 24-hour window. This finding BEST represents which type of quality indicator?
- Compliance indicator (Correct answer)
- Outcome indicator
- Sentinel event indicator
- Efficiency indicator
Correct answer: Compliance indicator
A compliance indicator measures adherence to established standards or protocols, such as timely completion of assessments.
Question 4: Which statistical tool is used in quality control to determine whether a process is in a 'state of statistical control'?
- Control chart (Shewhart chart) (Correct answer)
- Pareto chart
- Fishbone diagram
- Scatter plot
Correct answer: Control chart (Shewhart chart)
Control charts use upper and lower control limits to distinguish normal process variation from special cause variation, indicating statistical control.
Question 5: A foodservice operation conducts a HACCP plan review after receiving a supplier recall notice. Which HACCP principle is being applied when the team re-evaluates the receiving critical control point?
- Corrective action and verification (Correct answer)
- Hazard analysis
- Establishing monitoring procedures
- Establishing critical limits
Correct answer: Corrective action and verification
Reviewing and adjusting responses to a potential hazard at a CCP and verifying the plan remains effective applies the corrective action and verification principles.

- Check (Correct answer)
- Plan
- Do
- Act
Correct answer: Check
The Check phase involves studying the results of the intervention by comparing data against the expected outcomes.
Question 7: A long-term care facility wants to benchmark its malnutrition screening rates. What is the PRIMARY purpose of benchmarking in quality assurance?
- To compare performance against external standards or peer organizations (Correct answer)
- To discipline staff who fail to meet internal targets
- To calculate the cost per malnutrition screening
- To eliminate the need for internal audits
Correct answer: To compare performance against external standards or peer organizations
Benchmarking compares an organization's performance metrics to those of leading peers or established standards to identify gaps and improvement opportunities.
