NURS 4100: QUALITY AND SAFETY
THROUGH EVIDENCE-BASED
PRACTICE QUESTIONS AND ANSWERS
1. A nurse is conducting a Root Cause Analysis (RCA) after a sentinel event. Which
characteristic distinguishes an RCA from other quality improvement processes?
A. It focuses solely on the individual performance of the staff involved.
B. It is a proactive approach used to predict potential system failures before they happen.
C. It is a retrospective process that identifies underlying system vulnerabilities.
D. It is primarily used to assign blame and determine disciplinary actions.
Answer: C
Conceptual Explanation: Root Cause Analysis (RCA) is a retrospective method used to
look back at an event to identify system-level vulnerabilities rather than focusing on
individual human error.
2. According to the IOM (now National Academy of Medicine) report, ‘To Err is Human,’ what
is the primary cause of errors in the healthcare system?
A. Faulty systems and processes.
,B. Lack of patient education and compliance.
C. Incompetence of medical professionals.
D. High patient-to-nurse ratios.
Answer: A
Conceptual Explanation: The report fundamentally shifted the focus from individual
blame to the understanding that most errors result from faulty systems, processes, and
conditions.
3. Which component of the PICOT framework represents the ‘C’?
A. Comparison
B. Control
C. Conflict
D. Context
Answer: A
Conceptual Explanation: In PICOT (Patient/Population, Intervention, Comparison,
Outcome, Time), C stands for Comparison, which is the alternative to the intervention being
studied.
4. A hospital implements a ‘Just Culture’ policy. How does this policy affect error reporting?
A. Staff are terminated for any error resulting in patient harm.
B. Disciplinary actions are abolished regardless of the intent of the action.
, C. Staff are held accountable for reckless behavior but supported during human errors.
D. Errors are reported anonymously to the state board of nursing automatically.
Answer: C
Conceptual Explanation: Just Culture distinguishes between human error (unintentional),
risky behavior (choices made), and reckless behavior (disregard for safety), promoting
accountability without fear of unfair punishment.
5. Which QSEN competency focuses on minimizing risk of harm to patients through system
effectiveness and individual performance?
A. Safety
B. Informatics
C. Evidence-Based Practice
D. Quality Improvement
Answer: A
Conceptual Explanation: The Safety competency of Quality and Safety Education for
Nurses (QSEN) is specifically defined by minimizing risk of harm.
6. In the PDSA cycle of Quality Improvement, what occurs during the ‘Study’ phase?
A. The team implements the change on a small scale.
B. The team analyzes the data to determine if the goal was met.
C. The team plans the next cycle of improvement.
