PREP OBJECTIVE ASSESSMENT 2026/2027
COMPLETE QUESTIONS AND VERIFIED
CORRECT SOLUTIONS WITH RATIONALES
//100% ARANTEED PASS RECENT VERSION
Assessment Test - ANSWERconducted early in or midway through the
development of a product application. After the organization and general
design are determined, this kind of test assesses lower-level operations of the
application, stressing the efficiency goals of the product (versus
effectiveness) and how well the task is presented to users.
conducted whens system partially developed
validation test - ANSWERcompleted later in the systems life cycle using a
more mature product. This type of test assesses how this particular product
compares to a predetermined standard, benchmark, or performance measure.
weaknesses of agile process: - ANSWER requires meaningful stakeholder
participation
Agile cannot define what will be delivered at the end of a project.
,Agile requires a strong team of process subject matter experts.
No "Scrum Master" role. Unlike with software development teams, in
healthcare there is likely no one who is coaching the team on Agile practices,
such as defining work in iterations. This is where a subject matter lead role,
sponsor, or even project manager will need to lead.
The team needs to function at a high level, and thus requires experienced
team members with high levels of demonstrated professionalism.
Systems Life Cycle SLC - ANSWERAnalyze: The existing environment and
systems are evaluated. Major problems and deficiencies are identified using
informal or formal methods. A needs assessment is developed. Gaps are
noted and current capabilities and limitations are outlined. Initial user and
system requirements are formulated.
•Plan: The proposed system is planned comprehensively. Planning includes
strategic levels, such as whether the system will be developed internally,
purchased and tailored, or designed and developed jointly with a vendor.
•Develop or purchase: At this stage either the system is purchased or the new
system development begins. New components and programs are obtained and
installed. For vendor-supported solutions, extensive tailoring occurs.
•Test: At this stage extensive testing occurs just before Stage 5 and "go" or
"no go" decisions are made about deadlines. Toward the end of this phase,
marketing and communication efforts are accelerated to make users aware of
the impending change.
,•Implement or go-live: The system is implemented using a selected method
best suited to the organization and its tolerance for risk. User training is
completed.
•Maintain and evolve: Once the system has been formally acknowledged as
passing user acceptance testing, typically at 90 or 120 days after go-live, it
enters a maintenance phase.
•Evaluate: Activities in each phase are assessed for their quality and
effectiveness.
workaround - ANSWERa method used to circumvent a problem without
solving it
ADT Testing - ANSWERADT testing involves testing for every possible
type of ADT transaction used in the organization for inpatients, outpatients,
serial patients, and preadmits. These transactions include admit; discharge;
transfer; cancel admit; cancel discharge; cancel transfer; change beds, rooms,
or departments; merge accounts; etc.
Unit Testing and functional testing - ANSWERUnit testing is a very basic
type of testing where the tester runs through the basic functionalities and
features of an application. It is a high-level cursory walk-through of the
application. The goal is to identify deviations from the expectations and to
correct these unexpected results. The tester will not test every order or
documentation field but will need to test every possible scenario.
integrated testing - ANSWERIntegrated testing tests the transmission of
, messages between all systems such as the healthcare information system,
laboratory, radiology, pharmacy, dietary, cardiology, etc. This test includes
testing all bidirectional order messages and results going across the
interface(s)
ARRA-related Meaningful Use testing - ANSWERWith the introduction of
Meaningful Use, eligible providers, hospital organizations, and Critical
Access Hospitals (CAH) must test their ability to collect required information
and demonstrate that they meet Meaningful Use criteria.
big bang go live - ANSWERoccurs when all applications or modules are
implemented at once. This approach is favored by vendors and facilities
conducting large upgrades
phased go live - ANSWERboth paper and electronic environments exist at
the same time within the healthcare institution; however, the existence of
both paper and electronic environments forces the clinician to use different
work flows in patient units that have implemented the system than in units
that have not, potentially creating safety concerns.
ten key principles relevant to successful clinical systems integration. -
ANSWERComprehensive Services across the Continuum of Care, Patient
Focus, Geographic Coverage and Rostering, Standardized Care Delivery
through Interprofessional Teams, Performance Management, Information
Systems, Organizational Culture and Leadership, Physician Integration,
Governance Structure, and Financial Management
point of service (POS) - ANSWERdevice is a computer or information
