Exam Preparation Newest With Complete Questions
And Correct Detailed -Answer-: s| Brand New Version
1. What are the benefits of Health Information System (HIS) implementation?
-Answer-: :
Improves cost control, increases timeliness and accuracy of care/administration
data, increases service capacity, reduces personnel costs and inventory levels, and
improves patient care quality.
Explanation:
HIS automates workflows, reduces duplication, minimizes errors, supports real-
time documentation, and improves resource allocation, resulting in better
financial and clinical outcomes.
2. What is the role of the Nurse Informaticist in an HIS?
-Answer-: :
Seeks information, verifies ownership of data, and connects stakeholders across
the organization.
Explanation:
They bridge clinical staff and IT teams, ensuring systems support nursing
workflows, maintain data integrity, and improve care delivery.
3. What are the phases of Lewin’s Change Model?
,-Answer-: :
Unfreezing → Changing → Refreezing.
Explanation:
• Unfreezing: Prepare organization for change
• Changing: Implement new processes
• Refreezing: Stabilize and sustain change
Used commonly during HIS implementation.
4. What are the components of Shannon & Weaver’s Mathematical Model of
Communication?
-Answer-: :
Encoder → Channel → Decoder → Receiver.
Explanation:
Message is encoded into signals, transmitted through a channel, decoded, and
received. In healthcare IT, this models how electronic data is transmitted
accurately.
5. What are Bloom’s Knowledge Discovery/Data Mining steps?
-Answer-: :
Selection → Preprocessing → Transformation → Data Mining → Interpretation.
Explanation:
Raw data is cleaned and structured before analysis to discover patterns that
inform clinical or administrative decisions.
6. What is the role of the Chief Information Officer (CIO) in HIS implementation?
-Answer-: :
Oversees IT operations and advises executives on technology strategy and
purchases.
, Explanation:
The CIO aligns technology with organizational goals, budgets systems, ensures
security, and leads digital transformation.
7. What are the Solution Life Cycle (SLC) phases?
-Answer-: :
Discover/Analyze/Recommend → Design/Develop/Integrate → Test/QA →
Deploy/Maintain → Evaluate → Archive/Retire.
Explanation:
Covers the entire system lifespan from planning through retirement.
8. What are the phases of the Systems Development Life Cycle (SDLC)?
-Answer-: :
Requirements → Design → Implementation → Testing → Deployment →
Maintenance.
Explanation:
Standard structured approach to developing information systems.
9. What are the Waterfall Model phases?
-Answer-: :
Requirements → Design → Implementation → Integration/Testing →
Operation/Maintenance.
Explanation:
Linear process with no overlap; each phase must finish before the next begins.
10. What is the Agile Model?
