N3321 Nursing Quality & Safety Actual
Exam 2026/2027 | Verified Questions
Higher Education Nursing Curriculum | Verified Q&A |
University-Level Nursing Students
This document contains 50 original questions developed to reinforce the official course objectives of N3321 Nursing
Quality & Safety. The questions address Quality Improvement Models and Methodologies, Patient Safety and Error
Reporting Systems, Evidence-Based Practice and Clinical Guidelines, and Leadership, Ethics, and Regulatory
Compliance in Healthcare. Content is designed to support clinical proficiency and actual exam readiness for
University-Level Nursing Students. All material is original and aligned with N3321 course materials, foundational
nursing leadership and quality textbooks, and current evidence-based patient safety standards from organizations
such as the Institute of Medicine, Agency for Healthcare Research and Quality (AHRQ), and The Joint Commission
for the 2026/2027 cycle.
Domain: Quality Improvement Models and Methodologies
1. Which quality improvement model uses a cyclical process of Plan, Do, Study, and Act to test and
refine changes on a small scale?
A. Six Sigma DMAIC
B. PDSA (Plan-Do-Study-Act) cycle
C. Lean value-stream mapping only
D. Root cause analysis without iteration
Correct Answer: A
Rationale: The PDSA cycle is a foundational iterative model for testing changes in real-world settings before full
implementation.
2. In the Lean methodology applied to healthcare, what is the primary focus?
A. Reducing waste and non-value-added steps while improving flow and value for the patient
B. Increasing inventory of all supplies
C. Maximizing the number of steps in every process
D. Eliminating all standardized work
Correct Answer: C
Rationale: Lean targets elimination of waste (muda) and creation of smooth, patient-centered value streams.
3. What does the acronym DMAIC stand for in Six Sigma?
A. Define, Measure, Analyze, Improve, Control
B. Design, Monitor, Assess, Implement, Check
C. Develop, Manage, Audit, Inspect, Correct
D. Diagnose, Modify, Act, Integrate, Confirm
Correct Answer: D
Rationale: DMAIC is the structured problem-solving framework used in Six Sigma projects.
4. Which tool is commonly used in quality improvement to display the frequency of problems in
descending order so that the “vital few” can be prioritized?
A. Run chart
B. Pareto chart
C. Scatter diagram
D. Control chart only
Correct Answer: C

, Rationale: A Pareto chart ranks categories by frequency or impact, supporting the 80/20 principle.
5. What is the primary purpose of a run chart in quality improvement?
A. To display data over time so that trends, shifts, and patterns can be visualized
B. To show the relationship between two continuous variables only
C. To list every possible root cause in a hierarchy
D. To calculate the exact p-value of a process change
Correct Answer: A
Rationale: Run charts plot a quality indicator chronologically, making special-cause variation visible.
6. Which quality improvement approach emphasizes rapid-cycle testing of small changes with
frontline staff involvement?
A. Traditional large-scale redesign without pilot testing
B. The Model for Improvement combined with PDSA cycles
C. A one-time external audit only
D. Exclusive reliance on retrospective chart review
Correct Answer: B
Rationale: The Model for Improvement (aim, measures, changes) paired with PDSA enables rapid learning and adaptation.
7. In a control chart, what do the upper and lower control limits represent?
A. The statistical boundaries of common-cause variation for the process
B. The clinical goals set by the medical staff
C. The absolute minimum and maximum possible values of the measure
D. Arbitrary lines drawn for visual appearance
Correct Answer: D
Rationale: Control limits are calculated from the process data itself and distinguish common-cause from special-cause
variation.
8. What is the primary goal of a value-stream map in Lean healthcare projects?
A. To visualize the current state of a process, identify waste, and design a future state with improved flow
B. To list every medication error that has ever occurred
C. To replace the need for any data collection
D. To calculate the return on investment of a new building
Correct Answer: A
Rationale: Value-stream mapping makes the entire process visible so that non-value-added steps can be targeted for removal.
9. Which of the following is a key principle of continuous quality improvement (CQI) in nursing?
A. Quality is everyone’s responsibility and improvement is an ongoing, data-driven process
B. Quality is solely the responsibility of the quality department
C. Improvement occurs only after a major adverse event
D. Data collection is unnecessary once a process is designed
Correct Answer: D
Rationale: CQI embeds the expectation that all staff continuously seek opportunities to improve care using data.
10. What is the purpose of a fishbone (Ishikawa) diagram in quality improvement?
A. To systematically display potential categories of root causes contributing to a problem
B. To plot data points over time
C. To rank problems by frequency only
D. To calculate process capability indices
Correct Answer: D
Rationale: The fishbone diagram organizes brainstormed causes into major categories (e.g., people, process, environment) to
guide further investigation.
11. In the context of quality improvement, what does “special-cause variation” indicate?
A. A signal that something unusual has affected the process and warrants investigation
B. The normal, expected fluctuation of a stable process
C. A guaranteed improvement in outcomes
