CEHRS Systems and Technology 3 — Questions and Answers
Question 1: Which network topology connects all devices to a single central hub or switch?
- Star topology (Correct answer)
- Bus topology
- Ring topology
- Mesh topology
Correct answer: Star topology
In a star topology, every device connects to a central hub or switch, making it easy to isolate failures and manage traffic.
Question 2: A hospital configures its EHR so that nurses can document vitals but cannot prescribe medications. This is an example of:
- Role-based access control (RBAC) (Correct answer)
- Two-factor authentication
- Audit logging
- Data encryption
Correct answer: Role-based access control (RBAC)
Role-based access control grants system permissions based on a user's job role, limiting access to only the functions needed for that role.
Question 3: The process of converting paper health records into digital format using a scanner is called:
- Document imaging (Correct answer)
- Data migration
- Interface mapping
- Optical character recognition
Correct answer: Document imaging
Document imaging captures paper records as digital images stored within or linked to the EHR system.
Question 4: Which wireless standard is most commonly used for medical devices to communicate with EHR systems on hospital networks?
- Wi-Fi (IEEE 802.11) (Correct answer)
- Bluetooth LE
- Zigbee
- NFC
Correct answer: Wi-Fi (IEEE 802.11)
Wi-Fi (IEEE 802.11) is the primary wireless standard used in healthcare settings because it supports high data throughput and broad device compatibility.
Question 5: An EHR system automatically populates a patient's medication list from pharmacy dispensing records. This workflow is an example of:
- Automated data integration (Correct answer)
- Manual chart reconciliation
- Clinical coding
- Eligibility verification
Correct answer: Automated data integration
Automated data integration pulls information from external systems (e.g., pharmacy) directly into the EHR without manual entry.
Question 6: Which system converts spoken dictation into typed text that is imported into the EHR?
- Speech recognition software (Correct answer)
- Optical character recognition (OCR)
- Computer-assisted coding (CAC)
- Natural language processing (NLP) abstraction
Correct answer: Speech recognition software
Speech recognition software captures a provider's dictation and converts it to text, which is then inserted into the appropriate EHR field or document.
Question 7: A disaster recovery plan's Recovery Time Objective (RTO) defines:
- The maximum acceptable downtime before systems must be restored (Correct answer)
- The maximum tolerable data loss measured in time
- The total cost of system restoration
- The minimum number of backup copies required
Correct answer: The maximum acceptable downtime before systems must be restored
RTO specifies how quickly a system must be restored after an outage before the downtime becomes unacceptable to the organization.
