BTC Technology Integration & Support 2 — Questions and Answers
Question 1: A hospital is integrating a new infusion pump with its electronic health record (EHR) system via HL7 interface. Which data element is most critical to verify during initial testing?
- Patient identifier mapping accuracy (Correct answer)
- Pump battery charge level
- Nurse station network bandwidth
- Infusion set lot number
Correct answer: Patient identifier mapping accuracy
Correct patient identifier mapping prevents medication errors by ensuring pump data is associated with the right patient record.
Question 2: Which cybersecurity framework is most commonly referenced by healthcare organizations when assessing medical device security risks?
- ISO 9001
- NIST Cybersecurity Framework (Correct answer)
- IEC 61850
- IEEE 802.11ax
Correct answer: NIST Cybersecurity Framework
The NIST Cybersecurity Framework provides a widely adopted structure for identifying, protecting, detecting, responding to, and recovering from cybersecurity threats in healthcare.
Question 3: A biomedical technician discovers that an MRI-compatible patient monitor loses wireless connectivity near the magnet bore. What is the most appropriate corrective action?
- Replace the monitor with a wired model
- Reposition or add a wireless access point outside the 5-Gauss line (Correct answer)
- Disable the MRI system's RF shielding temporarily
- Upgrade the monitor firmware remotely
Correct answer: Reposition or add a wireless access point outside the 5-Gauss line
Placing a wireless access point outside the 5-Gauss line avoids interference while maintaining wireless coverage for the monitor.
Question 4: When onboarding a new vendor-managed device to the hospital network, which step should a biomedical technician complete FIRST?
- Assign a static IP address
- Complete a cybersecurity risk assessment and obtain IT approval (Correct answer)
- Install antivirus software on the device
- Connect the device to the clinical VLAN
Correct answer: Complete a cybersecurity risk assessment and obtain IT approval
A cybersecurity risk assessment and IT approval must precede network connection to identify vulnerabilities before the device is exposed to clinical systems.
Question 5: A technician is configuring a medical device gateway that aggregates data from multiple bedside monitors. Which protocol is specifically designed for this type of medical device interoperability?
- MQTT
- HL7 FHIR
- IEEE 11073 (Medical Device Communications) (Correct answer)
- SNMP
Correct answer: IEEE 11073 (Medical Device Communications)
IEEE 11073 is the international standard specifically designed for point-of-care medical device communication and data exchange.
Question 6: During EHR integration testing, a ventilator's tidal volume readings are consistently displayed 10% lower than the device screen shows. What is the most likely cause?
- Unit-of-measure mismatch in the interface mapping (Correct answer)
- Ventilator sensor calibration drift
- EHR database storage overflow
- Network packet loss corrupting values
Correct answer: Unit-of-measure mismatch in the interface mapping
A unit-of-measure mismatch in the HL7 or FHIR mapping (e.g., mL vs. L scaling error) is the most common cause of systematic numeric discrepancies during integration.
Question 7: Which document must a biomedical technician obtain from a medical device manufacturer before integrating the device with hospital IT systems?
- 510(k) clearance letter
- Medical Device Security MDS2 form (Correct answer)
- FDA 510(b) supplement
- ISO 13485 certificate
Correct answer: Medical Device Security MDS2 form
The MDS2 (Manufacturer Disclosure Statement for Medical Device Security) provides cybersecurity details needed to assess integration risks.
