CTC Equipment Operation & Maintenance 3 — Questions and Answers
Question 1: A videoconferencing unit in a rural clinic repeatedly drops the connection mid-visit. Network speed tests show adequate bandwidth. What should the coordinator investigate next?
- Packet loss and network jitter on the connection (Correct answer)
- The clinician's speaking volume
- The patient's insurance coverage for telehealth
- Whether the clinic uses a firewall
Correct answer: Packet loss and network jitter on the connection
High packet loss and jitter cause dropped connections and poor video quality even when raw bandwidth appears sufficient.
Question 2: Which type of power protection device is most important to deploy with telehealth carts to prevent equipment damage from sudden power loss?
- Surge protector power strip
- Uninterruptible Power Supply (UPS) (Correct answer)
- Extension cord with circuit breaker
- Power distribution unit (PDU) only
Correct answer: Uninterruptible Power Supply (UPS)
A UPS provides battery backup so telehealth equipment can be properly shut down or continue operating briefly during a power outage, protecting hardware and open sessions.
Question 3: A telehealth coordinator is setting up equipment in a patient's home. Which environmental factor poses the greatest risk to remote monitoring device accuracy?
- The color of the patient's walls
- Extreme temperatures outside the device's operating range (Correct answer)
- The brand of the patient's home router
- The distance from the nearest hospital
Correct answer: Extreme temperatures outside the device's operating range
Operating medical devices outside their specified temperature range can cause sensor inaccuracies, battery failures, or permanent hardware damage.
Question 4: What does the term 'latency' refer to in the context of telehealth videoconferencing equipment performance?
- The time delay between sending and receiving audio/video data (Correct answer)
- The maximum resolution the camera can capture
- The encryption strength of the connection
- The storage capacity of the telehealth cart's hard drive
Correct answer: The time delay between sending and receiving audio/video data
Latency is the round-trip delay in data transmission, and high latency creates disruptive audio/video lag during clinical consultations.
Question 5: A coordinator is performing a pre-visit equipment check and notices the telehealth cart's battery shows 20% charge. What is the correct action?
- Proceed with the visit since 20% is sufficient for a short consultation
- Connect the cart to AC power before starting the visit (Correct answer)
- Notify the patient that the visit must be rescheduled
- Replace the battery immediately
Correct answer: Connect the cart to AC power before starting the visit
Connecting to AC power before the visit prevents an unexpected shutdown mid-consultation that could disrupt patient care.
Question 6: Which protocol is most commonly used to secure audio and video streams transmitted during telehealth encounters?
- FTP (File Transfer Protocol)
- SRTP (Secure Real-time Transport Protocol) (Correct answer)
- HTTP (HyperText Transfer Protocol)
- SNMP (Simple Network Management Protocol)
Correct answer: SRTP (Secure Real-time Transport Protocol)
SRTP encrypts real-time audio and video streams, making it the standard protocol for securing telehealth communications.
Question 7: A telehealth organization is expanding to provide services across state lines. What equipment documentation must be maintained to comply with multi-state medical device regulations?
- Marketing materials for each state
- FDA registration records and state-specific biomedical equipment certifications where required (Correct answer)
- Only the original purchase receipts
- Clinician licensure documentation
Correct answer: FDA registration records and state-specific biomedical equipment certifications where required
Medical devices used in telehealth must maintain FDA registration and comply with any additional state biomedical engineering or inspection requirements.
