A hospital implements a new checklist to reduce central line infections, then measures infection rates monthly to evaluate improvement. Which quality improvement tool is being used?
- A Root cause analysis
- B Control chart
- C Fishbone diagram
- D Gantt chart
Correct answer: Control chart
Control charts monitor process performance over time and assess whether interventions result in meaningful changes.
A team performs a structured investigation after a wrong-site surgery. They examine system-level contributors such as communication lapses and documentation errors. This process is called:
- A Plan–Do–Study–Act cycle
- B Root cause analysis
- C Failure mode and effects analysis
- D Benchmarking
Correct answer: Root cause analysis
Root cause analysis is used after adverse events to identify underlying system factors rather than individual blame.
A hospital wants to prevent medication dosing errors before they occur by mapping potential failure points in the ordering process. Which tool should be used?
- A Root cause analysis
- B Failure mode and effects analysis
- C Ishikawa diagram
- D Run chart
Correct answer: Failure mode and effects analysis
FMEA proactively evaluates potential failures and their impact before errors occur, helping design safer systems.
A clinic compares its diabetic foot amputation rates with national averages to identify improvement opportunities. This process is best described as:
- A Internal audit
- B Benchmarking
- C Sentinel event review
- D Root cause analysis
Correct answer: Benchmarking
Benchmarking compares performance metrics with external standards to identify gaps and improvement targets.
A team uses an Ishikawa diagram to categorize possible contributors to delays in patient discharge. What type of tool is this?
- A Cause-and-effect analysis
- B Process control tool
- C Error prevention algorithm
- D Workflow efficiency map
Correct answer: Cause-and-effect analysis
The fishbone or Ishikawa diagram organizes potential causes of a problem under major categories to identify key contributors.
A hospital tests a new electronic alerts system in one department before expanding it hospital-wide. Which QI model is being used?
- A Lean methodology
- B Six Sigma
- C Plan–Do–Study–Act
- D Root cause analysis
Correct answer: Plan–Do–Study–Act
PDSA introduces small-scale tests of change, studies the effects, and adjusts accordingly before broader implementation.
A nurse reports a near-miss event involving a mislabeled medication. Which approach encourages this type of reporting?
- A Blame-free culture
- B Strict punitive policies
- C Ignoring minor events
- D Mandating disciplinary action
Correct answer: Blame-free culture
A blame-free or just culture encourages reporting errors and near misses to improve systems rather than punish individuals.
A hospital uses Six Sigma for quality improvement. What is its primary goal?
- A Maximize institutional revenue
- B Reduce variation and defects
- C Improve staff satisfaction
- D Accelerate patient throughput
Correct answer: Reduce variation and defects
Six Sigma focuses on reducing process variation and defects through data-driven decision-making.
A patient receives the wrong vaccine due to similar packaging. A system redesign places vaccines in color-coded bins to prevent mix-ups. Which safety strategy is this?
- A Forcing function
- B Automation
- C Standardization
- D Redundancy
Correct answer: Standardization
Standardization reduces variability and decreases the risk of human error by organizing processes consistently.
A hospital implements independent double-checks before administering high-risk medications. What type of safety strategy is this?
- A Redundancy
- B Standardization
- C Lean process
- D Benchmarking
Correct answer: Redundancy
Redundancy involves multiple checks to prevent errors, especially for high-risk medications.
A patient falls while walking to the bathroom. The safety team asks why repeatedly until the underlying cause is revealed (e.g., poor lighting). Which technique is this?
- A Five Whys
- B Fishbone analysis
- C Run charting
- D Benchmarking
Correct answer: Five Whys
The Five Whys technique uncovers root causes by progressively asking why an event occurred.
A clinic examines wait times and plots them daily to identify patterns and assess interventions. What tool does this represent?
- A Run chart
- B Fishbone diagram
- C Pareto chart
- D SWOT analysis
Correct answer: Run chart
Run charts track data points over time to assess trends and the effectiveness of process changes.
A quality team identifies that 80% of medication errors come from 20% of system steps. Which tool illustrates this observation?
- A PDSA chart
- B Control chart
- C Pareto chart
- D Scatter plot
Correct answer: Pareto chart
Pareto charts apply the 80/20 rule to identify the small number of causes responsible for most issues.
A new electronic order system flags abnormal drug doses and prevents submission unless corrected. What type of safety mechanism is this?
- A Redundancy
- B Forcing function
- C Standardization
- D Root cause analysis
Correct answer: Forcing function
A forcing function prevents an incorrect action from being completed, helping avoid potentially harmful mistakes.
A hospital implements Lean methodology. What is the core goal of this approach?
- A Improve financial profit
- B Reduce waste and maximize value
- C Increase staffing levels
- D Standardize medication dosing
Correct answer: Reduce waste and maximize value
Lean reduces waste and non–value-added steps to improve efficiency and patient-centered value.
A QI team identifies variability in handoff quality between providers. They create standardized handoff templates. This intervention targets which principle?
- A Root cause analysis
- B Process reliability
- C Benchmarking
- D Five Whys
Correct answer: Process reliability
Creating standardized processes enhances reliability and reduces variability in performance.
A hospital reviews a serious medication error deemed a sentinel event. Which agency requires reporting and investigation of such events?
- A CDC
- B Joint Commission
- C FDA
- D CMS
Correct answer: Joint Commission
The Joint Commission requires reporting and investigation of sentinel events to promote patient safety.
A safety team investigates near-misses to understand vulnerabilities before actual harm occurs. This type of thinking is known as:
- A Reactive approach
- B Proactive risk assessment
- C Blame culture
- D Sentinel event review
Correct answer: Proactive risk assessment
Proactive risk assessment anticipates problems by analyzing near misses and weak points.
A clinic aims to reduce medication errors by simplifying the number of steps in the prescription process. This intervention best reflects:
- A Reducing complexity
- B Benchmarking
- C Root cause analysis
- D FMEA
Correct answer: Reducing complexity
Simplifying processes reduces opportunities for errors and increases system reliability.
A nurse forgets to scan a medication barcode before administration. A later review shows she was interrupted twice during prep. Which safety principle applies?
- A Human factors engineering
- B Punitive correction
- C Workflow redundancy
- D Benchmarking
Correct answer: Human factors engineering
Human factors engineering examines how interruptions, fatigue, and environmental elements influence performance.
