2026 QUESTIONS WITH SOLUTIONS
GRADED A+
◍ Database Management System (DBMS).
Answer: manipulate and control the data stored within the database to meet
the needs of the user. It controls the ability to create, read, write, and delete
data stored in the database.
◍ Cancer registry information system.
Answer: An information system that tracks information (including very
detailed information regarding diagnosis and treatment) about the patient's
cancer from the time of diagnosis to the patient's death
◍ Bots.
Answer: Perform automated tasks, such as gathering information and instant
messaging, thus relieving a person the responsibility of doing it
◍ Pharmacy information system (PIS).
Answer: A key tool in providing optimal patient care and assisting providers
in ordering, allocating, and administering medication, with a focus on
patient safety issues, especially medication errors
◍ Semantics.
Answer: Branch of linguistics dealing with the study of meaning, including
the ways meaning is structured in language and how changes in meanings
and form occur over time
◍ Multidimensional database model.
Answer: Model used in data warehouses in which data are collected from
, multiple sources, such as other databases, and then summarized 322
Glossary
◍ Acceptasnce testing.
Answer: type of testing that occurs after the go-live date. It tests the IS to
confirm that it is working as expected as per the contract, RFP response, and
any other documentation.
◍ Audit-reduction tools.
Answer: Tools that review the audit trail and compare it to criteria specified
by the CE, which eliminates routine entries such as the periodic backups
◍ personal health record (PHR).
Answer: electronic or paper health record maintained and updated by
individuals that can be used to collect, track, and share past and current
information about their health or the health of someone in their care
◍ chargemaster (charge description master [CDM]).
Answer: financial management form or software that contains information
about the healthcare facility's charges for the services it provides to patients
◍ Security Rule.
Answer: Rules that define the minimum that a CE must do to protect
electronic protected health information (ePHI)
◍ LOINC.
Answer: The preferred standardized terminology for laboratory data in
information systems and provides a standard set of codes and names for the
electronic reporting of laboratory results; Logical Observation Identifiers
Names and Codes
◍ Data comprehensiveness.
Answer: The patient's health record must be complete and all required data
must be included
◍ data manipulation.
Answer: allows the user to add and delete rows in a table and to sort, find,
, and compare
◍ Internal scanning.
Answer: Identifying changes within the healthcare facility that will impact
the information system
◍ Complex map.
Answer: This mapping represents multiple code combinations and
alternatives that are required to translate a source to a target code
◍ Data quality measure.
Answer: Mechanism to assign a quantitative figure to quality of care by
comparison to a criterion. Quality measurements typically focus on
structures or processes of care that have a demonstrated relationship to
positive health outcomes
◍ data standards.
Answer: allow us to share data in a uniform way
◍ Covered entity (CE).
Answer: A health plan, healthcare clearinghouse, or healthcare provider that
transmits any health information in electronic form for one of the covered
transactions
◍ Mainframe computers.
Answer: large computers that are used by the government and other
organizations that require speed and the ability to process large amounts of
data.
◍ Data precision.
Answer: Ensures that there is justification for the need to collect the data
◍ administrative information systems.
Answer: the first information systems to be used in healthcare, mainly
financial or business-oriented in nature
◍ Data cleansing.
Answer: The process of checking internal consistency and duplication as
, well as identifying outliers and missing data. In other words, it means
looking for errors or problems with the data, such as duplicate patients
◍ Query by example (QBE).
Answer: A query method whereby the user only has to point and click to
choose tables and fields contained in the database. The information system
then allows the user to choose whether the entries that meet those criteria
should be included or excluded from the query
◍ Data mapping.
Answer: Allows for connections between two systems
◍ Physical data model.
Answer: Model that shows how the data are physically stored within the
database. The users are not involved with this level of the database because
of its technical complexity
◍ Facility access controls.
Answer: Limit physical access to the data center and software to only
authorized information system staff
◍ Data mining.
Answer: process of extracting and analyzing large volumes of data from a
database for the purpose of identifying hidden and sometimes subtle
relationships or patterns and using those relationships to predict behaviors.
◍ Context-based authentication.
Answer: Controls access not only by the role that the employee has in the
CE but also by the individual data elements and the context in which the
user is working
◍ Data repository.
Answer: An open-structure database (not dedicated to the software of any
particular vendor or data supplier) in which data from multiple information
systems are stored so that an integrated, multidisciplinary (includes a variety
of healthcare providers) view of the data can be achieved in a single source
