WGU C854 – Advanced Capstone Practice Exam
(Difficult, Long, Most-Tested Questions with Rationales)
Question 1 – Interoperability Strategy (Scenario)
A hospital implements a new EHR. Laboratory results transmit successfully between systems, but
providers report that abnormal values are misinterpreted because units and terminology differ. Data are
exchanged correctly, yet meaning is inconsistent.
Which interoperability level is missing?
A. Technical interoperability
B. Functional interoperability
C. Semantic interoperability
D. Process interoperability
Answer: C
Explanation:
Technical exchange is working (data moves). The problem is meaning consistency (units/terminology
mismatch). Semantic interoperability ensures shared interpretation using standards like LOINC or
SNOMED.
Question 2 – Change Management (Application)
During implementation of a clinical decision support system, nurses resist adoption, claiming the alerts
slow workflow. The informaticist schedules education sessions and shares error-reduction data before
go-live.
Which Lewin stage is this?
,A. Refreezing
B. Changing
C. Unfreezing
D. Monitoring
Answer: C
Explanation:
Education and awareness reduce resistance and prepare users psychologically. That is Unfreezing.
Question 3 – Systems Thinking (Complex)
Medication errors persist despite multiple fixes. The informatics team maps inputs (orders), processes
(verification), outputs (administration), and feedback loops (incident reports).
Which principle is being applied?
A. Linear problem solving
B. Systems thinking
C. Data mining
D. Root cause coding
Answer: B
Explanation:
Systems thinking evaluates the entire workflow, not isolated tasks, to find interdependencies.
Question 4 – SDLC Selection (Evaluation)
A clinic knows all requirements upfront and regulatory constraints prevent mid-project changes.
Predictability is critical.
Which development model is most appropriate?
A. Agile
B. Iterative
C. Waterfall
D. Spiral
Answer: C
Explanation:
Waterfall is plan-driven with no phase overlap, ideal when requirements are fixed and compliance-
heavy.
Question 5 – Agile Advantage (Analysis)
, Why might Agile be preferred over Waterfall for a telehealth expansion project?
A. Requires less stakeholder involvement
B. Prevents requirement changes
C. Allows continuous user feedback and adaptation
D. Eliminates testing
Answer: C
Explanation:
Agile emphasizes iteration and flexibility, ideal when needs evolve.
Question 6 – Nurse Informaticist Role (Scenario)
A nurse informaticist notices duplicate charting between two systems and coordinates meetings with IT,
vendors, and nursing leadership to redesign workflows.
Primary role demonstrated?
A. Direct care provider
B. Technical coder
C. Liaison/translator
D. Financial auditor
Answer: C
Explanation:
Nurse informaticists bridge clinical and technical teams.
Question 7 – Standard Selection (Clinical Data Exchange)
Which standard should be used to transmit lab results electronically?
A. CPT
B. SNOMED
C. LOINC
D. ICD
Answer: C
Explanation:
LOINC codes labs and clinical observations.
Question 8 – Imaging Integration
A radiology department needs standardized storage and sharing of CT and MRI images.
