Informatics Nurse Test Nursing Informatics Data Analytics and Outcomes 1 — Questions and Answers
Question 1: In nursing informatics, which term describes the process of transforming raw clinical data into actionable knowledge?
- Data warehousing
- The DIKW (Data-Information-Knowledge-Wisdom) framework (Correct answer)
- Normalization
- Encryption
Correct answer: The DIKW (Data-Information-Knowledge-Wisdom) framework
The DIKW framework describes the progression from raw data to information, knowledge, and ultimately wisdom that guides clinical decision-making.
Question 2: Which analytics approach uses historical clinical data to identify what happened in a patient population?
- Predictive analytics
- Prescriptive analytics
- Descriptive analytics (Correct answer)
- Cognitive analytics
Correct answer: Descriptive analytics
Descriptive analytics summarizes historical data to answer the question 'What happened?' using metrics like infection rates, readmission counts, and fall rates.
Question 3: An informatics nurse is building a falls dashboard. Which data source would provide the MOST relevant outcome data?
- Financial billing records
- Incident reporting system linked to EHR fall risk assessments (Correct answer)
- Staff scheduling system
- Vendor support ticket log
Correct answer: Incident reporting system linked to EHR fall risk assessments
Linking incident reports to EHR fall risk assessments allows the nurse to correlate risk scores with actual fall events to measure prediction accuracy and intervention effectiveness.
Question 4: The National Database of Nursing Quality Indicators (NDNQI) collects data on nursing-sensitive indicators to:
- Track physician billing performance
- Benchmark nursing unit performance against national standards and improve patient outcomes (Correct answer)
- Monitor medication costs
- Manage nurse licensure renewals
Correct answer: Benchmark nursing unit performance against national standards and improve patient outcomes
NDNQI collects unit-level nursing quality data and provides benchmark comparisons to national averages, supporting evidence-based quality improvement.
Question 5: A nursing informatics specialist is interpreting a control chart. Data points outside the control limits indicate:
- Normal random variation
- Special cause variation requiring investigation (Correct answer)
- Data entry errors only
- Seasonal staffing patterns
Correct answer: Special cause variation requiring investigation
Points outside control limits represent special cause variation — non-random signals that warrant investigation to identify an assignable cause.
Question 6: Which data governance principle ensures that the same clinical data element means the same thing across all systems?
- Data provenance
- Data standardization (Correct answer)
- Data masking
- Data replication
Correct answer: Data standardization
Data standardization ensures that terminology, definitions, and coding systems are consistent across systems so the same data element is interpreted identically.
