CPHIMS CPHIMS Testing and System Evaluation 4 — Questions and Answers
Question 1: Which testing technique involves testing a system without knowledge of its internal code structure?
- White-box testing
- Gray-box testing
- Black-box testing (Correct answer)
- Static testing
Correct answer: Black-box testing
Black-box testing evaluates system functionality based solely on inputs and expected outputs, without knowledge of internal code or architecture.
Question 2: A healthcare organization wants to evaluate whether its new patient portal meets usability standards. Which testing method is most appropriate?
- Load testing
- Usability testing with representative end users (Correct answer)
- Penetration testing
- Regression testing
Correct answer: Usability testing with representative end users
Usability testing with representative end users directly measures whether the system meets usability standards and user experience expectations.
Question 3: In the context of CPHIMS, what is the main goal of system validation in healthcare IT?
- Confirm the system was built according to design specifications
- Ensure the system meets the intended use and user needs (Correct answer)
- Verify all code modules compile without errors
- Check network infrastructure meets bandwidth requirements
Correct answer: Ensure the system meets the intended use and user needs
Validation confirms that the system meets user needs and intended use in its operational environment, distinct from verification which checks design conformance.
Question 4: Which type of testing deliberately pushes a system beyond its normal operational capacity to identify breaking points?
- Load testing
- Stress testing (Correct answer)
- Volume testing
- Soak testing
Correct answer: Stress testing
Stress testing intentionally overloads a system beyond its specified capacity to identify failure thresholds and how the system recovers.
Question 5: What is the primary purpose of maintaining traceability matrices during healthcare IT testing?
- Track defect resolution timelines
- Link test cases to specific requirements to ensure complete coverage (Correct answer)
- Monitor tester productivity metrics
- Document go-live readiness criteria
Correct answer: Link test cases to specific requirements to ensure complete coverage
A requirements traceability matrix (RTM) maps each test case to a specific requirement, ensuring all requirements are tested and nothing is overlooked.
Question 6: After implementing a clinical information system, the CMIO notices medication error rates increased. What should be the first step in the evaluation process?
- Immediately roll back the system to the previous version
- Conduct root cause analysis to determine if the system contributed to the errors (Correct answer)
- Retrain all clinical staff on system use
- Disable the medication ordering module pending review
Correct answer: Conduct root cause analysis to determine if the system contributed to the errors
Root cause analysis should be conducted first to determine whether the system, workflow changes, training gaps, or other factors contributed to the increased error rates.
Question 7: Which testing approach is specifically designed to evaluate a system's behavior when input data falls at the edges of valid ranges?
- Equivalence partitioning
- Boundary value analysis (Correct answer)
- Decision table testing
- State transition testing
Correct answer: Boundary value analysis
Boundary value analysis tests input values at the exact boundaries of valid ranges, where errors are most likely to occur.
