CPHIMS CPHIMS Testing and System Evaluation 3 — Questions and Answers
Question 1: In healthcare IT, what does a 'test script' primarily contain?
- System configuration parameters
- Step-by-step instructions for executing a specific test case (Correct answer)
- List of all identified defects
- Performance benchmarking thresholds
Correct answer: Step-by-step instructions for executing a specific test case
A test script provides detailed, step-by-step instructions that a tester follows to execute a specific test case and verify expected results.
Question 2: Which testing environment best simulates real-world production conditions for final validation before go-live?
- Development environment
- Quality assurance (QA) environment
- Staging/pre-production environment (Correct answer)
- Training environment
Correct answer: Staging/pre-production environment
The staging or pre-production environment mirrors the production environment as closely as possible, making it ideal for final validation testing.
Question 3: When creating test cases for a clinical decision support system, which approach ensures the most comprehensive coverage?
- Testing only the most common clinical scenarios
- Using equivalence partitioning and boundary value analysis (Correct answer)
- Relying solely on end-user feedback
- Testing random data inputs
Correct answer: Using equivalence partitioning and boundary value analysis
Equivalence partitioning and boundary value analysis are systematic techniques that maximize test coverage while minimizing the number of test cases needed.
Question 4: A CPHIMS candidate is reviewing a post-implementation evaluation report. Which KPI best measures clinical workflow efficiency after EHR implementation?
- Number of system logins per day
- Average time to complete documentation per patient encounter (Correct answer)
- Total number of active user accounts
- Server uptime percentage
Correct answer: Average time to complete documentation per patient encounter
Average documentation time per encounter directly measures clinician workflow efficiency, which is a key clinical outcome of EHR implementation.
Question 5: What is the recommended approach when a critical defect is discovered during user acceptance testing (UAT)?
- Proceed to go-live and fix after deployment
- Document, prioritize, resolve, and retest before proceeding (Correct answer)
- Defer to the next system upgrade cycle
- Mark as a known issue and inform end users
Correct answer: Document, prioritize, resolve, and retest before proceeding
Critical defects found in UAT must be documented, assigned a priority, resolved by developers, and retested before the system can proceed to go-live.
Question 6: Which of the following best describes 'smoke testing' in healthcare IT system deployment?
- Testing system behavior under extreme load conditions
- A preliminary test to confirm basic functions work before deeper testing begins (Correct answer)
- Security vulnerability scanning before go-live
- End-user training validation testing
Correct answer: A preliminary test to confirm basic functions work before deeper testing begins
Smoke testing is a quick, high-level test that verifies the most critical functions work, ensuring the build is stable enough for more detailed testing.
Question 7: During system evaluation, which framework is most commonly used to assess the overall value of a healthcare IT investment?
- TOGAF
- COBIT
- Return on Investment (ROI) analysis (Correct answer)
- Agile Scrum framework
Correct answer: Return on Investment (ROI) analysis
ROI analysis measures the financial return relative to investment costs and is the most widely used framework for evaluating healthcare IT value.
