GUIDE 2026 FINAL REVIEW EXAM
◉ What describes the maintenance phase of the system
development life cycle? Answer: The system is upgraded
◉ Describe what phase of the system life cycle is the scope of the
proposed project identified. Answer: Planning
◉ What is the next step in the system life cycle after a new health
information system has been purchased? Answer: Test the system
◉ In which ways can the use of clinical decision support systems
affect health information technology and create a culture of safety
within healthcare. Answer: It improves quality of care
It improves patient satisfaction
◉ What is a major reason to install a clinical decision support
system within healthcare information technology Answer: It reduces
errors
◉ How does a clinical decision support system that uses ANSI and
WEDI support a culture of safety Answer: By standardizing
healthcare information
,ANSI: American National Standard Institute
WEDI: Workgroup for Electronic Data Interchange
◉ Why do healthcare facilities favor purchased information systems
over organization-developed information systems? Answer: System
enhancements are provided
◉ What step in the project implementation of the electronic health
record relies heavily upon the ability of the super users? Answer:
Manage go-live activities and post go-live support
◉ Which stage of the planning phase provides the high-level
direction needed to reach organizational goals? Answer: Strategic
Planning
◉ What initiates the life cycle of an information system Answer:
Identification of a vision or need
◉ Place the implementation steps of the electronic health record life
cycle in order from first to last Answer: 1. Identify the problem/
need, obtain approval and proceed with the project
2. Discover and understand the details or the need of the project
3.Build, test and integrate system components
4.Complete system test and then deploy the solution
, ◉ As a crucial part of the whole information technology (IT)
infrastructure (hardware, software, networks, operations, etc.) of the
organization, this step in the project implementation must be
aligned with the organization's mission and support the overall
business goals.
Which part of the project implementation plan would this be?
Answer: Strategic planning
◉ What is the correct order of the phases of an adaptive system
development life cycle with six core processes and multiple
iterations? Answer: 1. Identify the problem and obtain approval
2. Plan and monitor project
3. Discover and understand details
4. Design system components
5. Build, test, and integrate system components
6. Complete system tests and deploy the solution
◉ Which system development life cycle approach does the waterfall
model describe? Answer: A Sequential approach
