WGU D027 Healthcare Information Systems OA Exam
50 Questions | Verified Answers with Rationales
1. A hospital implements an Electronic Health Record (EHR) system. What is the
primary advantage of an EHR compared to a paper-based record?
A. Lower upfront cost
B. Improved accessibility and real-time data sharing
C. Elimination of all documentation errors
D. Reduced need for healthcare staff
Answer: B
Rationale: EHR systems allow authorized users to access patient data in real time
across departments, improving coordination and care quality. While EHRs reduce
some errors, they do not eliminate them entirely, and they often require
significant initial investment and staff training.
2. Which federal incentive program provided financial rewards to healthcare
providers who demonstrated meaningful use of certified EHR technology?
A. HIPAA Omnibus Rule
B. HITECH Act (Meaningful Use program)
C. Affordable Care Act
D. CURES Act
Answer: B
Rationale: The HITECH Act of 2009 established the Meaningful Use program, later
renamed Promoting Interoperability, which provided financial incentives for
adoption and meaningful use of certified EHR technology.
3. A healthcare organization wants to exchange patient information with an
outside hospital. What key technology enables this interoperability?
,A. Cloud storage
B. Health Information Exchange (HIE)
C. Personal health record (PHR)
D. Intranet
Answer: B
Rationale: A Health Information Exchange (HIE) allows secure sharing of
electronic health information across different organizations, enabling
interoperability between hospitals, clinics, and other providers.
4. A physician attempts to prescribe a medication that the patient is allergic to.
The EHR system alerts the physician before the order is placed. This functionality
is best described as:
A. Computerized Physician Order Entry (CPOE)
B. Clinical Decision Support System (CDSS)
C. Electronic Medication Administration Record (eMAR)
D. Revenue Cycle Management (RCM)
Answer: B
Rationale: Clinical Decision Support Systems (CDSS) provide real-time alerts and
reminders to clinicians, including allergy checks, drug-drug interactions, and
clinical guideline prompts.
5. Which of the following is a core requirement for Stage 1 Meaningful Use?
A. Patient access to health information within 24 hours
B. Electronic prescribing (eRx)
C. Automated hospital discharge summaries
D. Artificial intelligence-based diagnosis
Answer: B
Rationale: Stage 1 Meaningful Use focused on data capture and sharing, including
core objectives such as CPOE, e-prescribing, recording vital signs, and maintaining
active medication/allergy lists.
, 6. A hospital experiences a ransomware attack that encrypts patient records.
Which of the following is the primary compliance concern under HIPAA?
A. Lack of documentation
B. Breach of confidentiality and availability
C. Excessive staff training
D. Insufficient hardware upgrades
Answer: B
Rationale: HIPAA requires protection of ePHI for confidentiality, integrity, and
availability. A ransomware attack compromises availability (inability to access
data) and confidentiality (unauthorized access possible), making it a reportable
breach.
7. Which standard code set is required for electronic claims submission of
diagnoses in the United States?
A. CPT
B. HCPCS Level II
C. ICD-10-CM
D. SNOMED CT
Answer: C
Rationale: ICD-10-CM (International Classification of Diseases, 10th Revision,
Clinical Modification) is the standard for reporting diagnoses on HIPAA electronic
transactions.
8. A nurse manager wants to track how often a specific clinical protocol is
followed. Which EHR feature provides automated quality measurement?
A. Patient portal
B. Clinical dashboard and quality measures reporting
C. Transcription service
D. Scheduling module
