Question 1: What is the primary difference between an electronic medical record
(EMR) and an electronic health record (EHR)?
A) An EMR is used only in hospitals, while an EHR is used only in clinics
B) An EMR is a digital version of a paper chart from a single practice, while an
EHR is designed to be shared across multiple providers
C) An EMR is more secure than an EHR
D) An EHR is only used for billing purposes
Correct Answer: B
An EMR is a digital record used within a single practice or organization, whereas
an EHR is designed for interoperability and sharing across different healthcare
settings. Option A is incorrect because both can be used in various settings. Option
C is incorrect as security depends on implementation, not the type. Option D is
incorrect because EHRs support clinical care, not just billing.
Question 2: Which of the following is a key benefit of implementing an EHR
system?
A) Increased paper documentation
B) Improved care coordination and reduced medical errors
C) Decreased patient engagement
D) Elimination of all clinical workflows
Correct Answer: B
EHRs improve care coordination by making patient information readily available
to authorized providers and can reduce errors through alerts and standardized
documentation. Option A is the opposite. Option C is incorrect as EHRs often
include patient portals that enhance engagement. Option D is incorrect; workflows
are redesigned, not eliminated.
Question 3: What does the acronym HIE stand for in healthcare?
A) Health Information Exchange
B) Hospital Information Enterprise
C) Health Informatics Education
D) High Integrity Encryption
, 3
Correct Answer: A
HIE stands for Health Information Exchange, which refers to the electronic
movement of health-related information among organizations. Options B, C, and D
are incorrect expansions.
Question 4: Which organization is responsible for maintaining the ICD-10 coding
system in the United States?
A) World Health Organization (WHO)
B) Centers for Medicare & Medicaid Services (CMS)
C) American Medical Association (AMA)
D) National Library of Medicine (NLM)
Correct Answer: B
In the U.S., CMS and the National Center for Health Statistics (NCHS) are
responsible for maintaining ICD-10-CM and ICD-10-PCS. The WHO maintains
ICD but not the U.S. clinical modification. The AMA maintains CPT. The NLM
manages PubMed and other resources.
Question 5: What is the primary purpose of the Health Insurance Portability and
Accountability Act (HIPAA)?
A) To provide health insurance for all Americans
B) To protect the privacy and security of protected health information (PHI)
C) To standardize electronic health records
D) To regulate hospital reimbursements
Correct Answer: B
HIPAA's Privacy and Security Rules establish national standards for protecting
PHI. Option A is incorrect; HIPAA is not universal healthcare. Option C is related
but not the primary purpose. Option D is incorrect; reimbursement is regulated by
CMS.
Question 6: Which of the following is considered protected health information
(PHI) under HIPAA?
, 4
A) A patient's name and address
B) A hospital's annual budget
C) A doctor's personal phone number
D) A public health statistic with no identifiers
Correct Answer: A
PHI includes any information that can identify a patient and relates to their health,
care, or payment. Option B is organizational. Option C is not patient information.
Option D is de-identified and not PHI.
Question 7: What does the HITECH Act primarily address?
A) Expanding the use of health information technology and strengthening privacy
protections
B) Regulating pharmaceutical prices
C) Funding hospital construction
D) Establishing Medicare Part D
Correct Answer: A
The HITECH Act promotes the adoption of EHRs and strengthens HIPAA
enforcement. Option B is unrelated. Option C is not the focus. Option D is a
separate legislation.
Question 8: Which data standard is commonly used for exchanging clinical and
administrative data between healthcare systems?
A) HL7
B) DICOM
C) ICD-10
D) CPT
Correct Answer: A
HL7 (Health Level Seven) is a set of standards for exchanging clinical and
administrative data. DICOM is for medical imaging. ICD-10 is for diagnosis
coding. CPT is for procedure coding.
