STUDY GUIDE COMPLETE 300 QUESTIONS AND DETAILED
CORRECT SOLUTIONS 2024-2025
Q: Logical Observations Identifiers, Names, Codes (LOINC) is a terminology that originated for
documentation in which area of the healthcare industry? - ANSWER-Laboratory - LOINC
originated to share lab test orders and results. It has been expanded to include clinical
observations (vitals signs) and bedside glucometer results. U.S. Federal Government uses LOINC
for the electronic exchange of clinical health information.
Q: RxNorm is a terminology that originated for documentation in which area of the healthcare
industry? - ANSWER-Pharmacy - Rx Norm is standardized nomenclature for clinical drugs for
humans and is used by the U.S. Federal Government for electronic exchange of clinical health
information.
Q: True or False. Taxonomies categorize data to make it searchable and usable. - ANSWER-True
- Taxonomy is a way to classify words in groupings, which makes them usable and searchable.
Q: Which standardized nursing terminology comprises nursing diagnoses, nursing interventions,
and nursing outcomes? - ANSWER-ICNP - the nursing terminology used for the International
Classification if Nursing Practice that crosses all the nursing concepts across terminologies. It's
intended to facilitate the comparison of nursing data with data from other health disciplines.
Q: Which are examples of clinical decision support? - ANSWER-Medication Administration Vital
Sign Notification, Latex Allergy Alert, Duplicate Medication Notification. Clinical Decision
Support (CDS) supports clinical decision-making by providing information to support decision-
making. CDS promotes best practices. These tasks help clinicians prevent adverse medical
events.
Q: What type of terminology is PNDS - Perioperative Nursing Data Set? - ANSWER-Interface
Terminology

Q: What type of terminology is SNOMED - Systematic Nomenclature of Clinical Medicine terms?
- ANSWER-Interdisciplinary Terminology
Q: What type of terminology is Nursing Management Minimum Dataset? - ANSWER-Data
Element Set
Q: What type of terminology is LOINC - Logical Observation Identifiers Names and Codes? -
ANSWER-Reference Terminology
Q: True or False. A class waterfall model of SDLC has overlapping phases. - ANSWER-False -
Most predictive SDLC approach (farthest to the left on the predictive/adaptive scale) is called a
waterfall model, with the project phases flowing down, one after another. The waterfall model
is an SDLC approach that assumes the phases can be completed sequentially with no overlap.
Q: An organization is interested in implementing telehealth in its ambulatory clinics. Although
they have experience with telehealth in the emergency department, some requirements of the
ambulatory clinics are not yet clearly identified. Which of the following should the organization
adopt for their implementation planning? - ANSWER-Agile - Agile development is a guiding
philosophy and guideline for developing information systems in an unknown, rapidly changing
environment. Examples include Scrum, eXtreme programming (XP), adaptive software
development (ASD), and lean software development (LSD).
Q: The SDLC Phase called Planning goes with what task? - ANSWER-Needs Assessment
Q: The SDLC Phase called Analysis goes with what task? - ANSWER-Workflow Process
Q: The SDLC Phase called Design/Development goes with what task? - ANSWER-Configuration
Q: The SDLC Phase called Implementation and Testing goes with what task? - ANSWER-End-
User Training

Q: The SDLC Phase called Monitoring, Maintaining, Supporting, and Evaluating goes with what
task? - ANSWER-Help Desk Support
Q: What System Development Life Cycle (SDLC) approach assumes the project can be planned
completely in advance? - ANSWER-Predictive - Predictive SDLCs are useful for building systems
that are well understood and defined. A company may want to convert its old networked
client/server system to a newer Wed-based system that includes a smartphone app. The
predictive approach applies because the staff already understands the requirements very well,
and no new processes need to be added. The project can be carefully planned, and the system
can be built according to the specifications.
Q: A primary care practice is seeking a patient portal for patients to access their healthcare
records. The practice manager has generated a list of four patient portals that work with the
practice's existing scheduling and billing system and electronic health record. What is the next
step in the project life cycle? - ANSWER-A letter is sent, called a request for proposal (RFP), to
potential vendors asking for specific information about the patient portal. - a letter to request
information (RFI) is sent to check for compatibility with existing systems and specific
information. Once that step is done, a letter is sent for more specific detail, called a request for
proposal (RFP) that provides detailed functionality, approximate costs, and an expected
timeline so the vendors that meet the practice's goals can be identified (budget, timing,
functionality, etc.).
Q: Place the Steps of the Staggers and Nelson Life Cycle in order from first to last (4). - ANSWER-
Implementation, Analysis/Planning, Design/Development, Maintenance/Support
Q: What describes the maintenance phase of the system development life cycle? - ANSWER-
System is upgraded
Q: During which phase of the system life cycle is the scope of the proposed project identified? -
ANSWER-Planning
Q: What is the next step in the system life cycle after a new health information system has been
purchased? - ANSWER-Test the System

Q: 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 and patient satisfaction.
Q: What is a major reason to install a clinical support system within healthcare information
technology? - ANSWER-Reduces errors.
Q: How does a clinical decision support system that uses ANSI and WEDI support a culture of
safety? - ANSWER-By standardizing healthcare information
Q: A large healthcare corporation is preparing to implement a new patient portal for healthcare
records. Multiple literature searches have been done, trade shows have been attended, and a
final list of potential vendors has been developed. What is the next step in the project life
cycle? - ANSWER-A letter is sent to potential vendors, asking for specific information about the
product.
Q: Why do healthcare facilities favor purchased information systems over organization-
developed information systems? - ANSWER-System enhancements are provided.
Q: Which system development life cycle uses the most predictive approach? - ANSWER-
Waterfall model
Q: Which step in the project implementation of the electronic health record relies heavily upon
the ability of super users? - ANSWER-Manage go-live activities and post go-live support
Q: Which stage of the planning phase provides the high-level direction needed to reach
organizational goals? - ANSWER-Strategic planning
Q: What initiates the life cycle of an information system? - ANSWER-Identification of a vision or
need
