TEST BANK – 200+ ORIGINAL QUESTIONS WITH
RATIONALES (COMPLETE TEST
PREPARATION)**
# SECTION 1: HEALTH INFORMATION SYSTEMS FUNDAMENTALS
(Questions 1–40)
**1.** An Electronic Health Record (EHR) is best defined as:
A) A digital version of a patient’s paper chart that contains data from a
single organization
B) A system that only stores billing and administrative data
C) A longitudinal digital record of patient health information that can be
shared across different healthcare settings
D) A tool used exclusively for scheduling appointments
**Correct Answer:** C – A longitudinal digital record of patient health
information that can be shared across different healthcare settings
**Rationale:** An EHR is a real-time, patient-centered digital record
that makes information available instantly and securely to authorized
users across multiple healthcare organizations. It is longitudinal,
covering a patient’s entire lifespan.

**2.** Which federal act provided financial incentives for the
meaningful use of certified EHR technology in the United States?
A) HIPAA (1996)
B) HITECH Act (2009)
C) Affordable Care Act (2010)
D) 21st Century Cures Act (2016)
**Correct Answer:** B – HITECH Act (2009)
**Rationale:** The Health Information Technology for Economic and
Clinical Health (HITECH) Act, part of the American Recovery and
Reinvestment Act of 2009, provided incentive payments to eligible
professionals and hospitals for adopting and demonstrating meaningful
use of certified EHRs.
**3.** In health informatics, the term “interoperability” refers to:
A) The ability of different information systems to exchange and use data
without special effort
B) The security of patient data
C) The speed of data processing
D) The size of the database
**Correct Answer:** A – The ability of different information systems to
exchange and use data without special effort
,3|Page
**Rationale:** Interoperability is a key goal of health IT, enabling
seamless data exchange between systems (e.g., EHR to lab system) to
support coordinated care. It includes technical, semantic, and process
interoperability.
**4.** Which of the following is an example of structured data in an
EHR?
A) A free-text progress note written by a physician
B) A scanned image of a lab report
C) A drop-down menu selection of “hypertension” from a coded
problem list
D) A dictated and transcribed discharge summary
**Correct Answer:** C – A drop-down menu selection of
“hypertension” from a coded problem list
**Rationale:** Structured data are discrete, coded, and machine-
readable (e.g., using SNOMED CT, ICD-10, LOINC codes).
Unstructured data include free text, images, and narrative notes.
**5.** The function of a master patient index (MPI) is to:
A) Store billing information
B) Assign a unique identifier to each patient and link all records for that
patient across systems
C) Track physician schedules
, 4|Page
D) Store laboratory test results
**Correct Answer:** B – Assign a unique identifier to each patient and
link all records for that patient across systems
**Rationale:** The MPI (or enterprise master patient index, EMPI)
ensures that all records for a given patient are correctly linked across
different departments, systems, and facilities, preventing duplicate
records.
**6.** Which of the following is a primary benefit of computerized
provider order entry (CPOE)?
A) Increased handwriting errors
B) Reduction in medication errors and improved legibility
C) Decreased efficiency for prescribers
D) Increased cost of care
**Correct Answer:** B – Reduction in medication errors and improved
legibility
**Rationale:** CPOE reduces errors from illegible handwriting,
provides decision support (e.g., allergy checking, dosing guidance), and
standardizes order communication. It is a core meaningful use
requirement.
**7.** The “five rights” of clinical decision support (CDS) are:
