CTP Telepresence and Technology 2 — Questions and Answers
Question 1: A clinician notices their telehealth video image appears pixelated and choppy during a session. Which metric should be checked first to diagnose the issue?
- Screen resolution settings
- Network bandwidth and packet loss (Correct answer)
- Camera lens cleanliness
- Monitor refresh rate
Correct answer: Network bandwidth and packet loss
Pixelated and choppy video is most commonly caused by insufficient bandwidth or packet loss on the network connection.
Question 2: Which lighting setup is considered best practice for a clinician conducting a telehealth video visit?
- Overhead fluorescent lighting directly above the clinician
- Natural light from a window behind the clinician
- Soft diffused light facing the clinician from in front (Correct answer)
- Dim ambient lighting to reduce eye strain
Correct answer: Soft diffused light facing the clinician from in front
Soft, diffused front-facing light illuminates the clinician's face clearly without harsh shadows or glare.
Question 3: A patient uses a tablet mounted on a stand during telehealth sessions. The camera angle points upward at their chin. What is the recommended fix?
- Ask the patient to tilt their head downward
- Raise the tablet so the camera is at eye level (Correct answer)
- Switch to a desktop computer
- Zoom out the camera view
Correct answer: Raise the tablet so the camera is at eye level
The camera should be positioned at eye level to simulate natural face-to-face interaction and avoid unflattering or obstructed views.
Question 4: Which type of internet connection is generally LEAST reliable for high-quality telehealth video sessions?
- Fiber optic broadband
- Cable broadband
- Satellite internet (Correct answer)
- 4G LTE mobile hotspot
Correct answer: Satellite internet
Satellite internet typically has high latency and variable bandwidth, making it less reliable for real-time video communication.
Question 5: During a telehealth visit, echo is heard when either party speaks. What is the most likely cause?
- Low camera resolution
- Audio feedback from speakers picked up by the microphone (Correct answer)
- Encryption processing delay
- Outdated video codec
Correct answer: Audio feedback from speakers picked up by the microphone
Echo occurs when a speaker's audio output is captured by the microphone and re-transmitted, creating a feedback loop.
Question 6: A telehealth platform uses end-to-end encryption. What does this mean for patient data transmitted during a video session?
- Data is encrypted only at the sending device and decrypted at the server
- Data is encrypted from the sender's device and can only be decrypted by the intended recipient (Correct answer)
- Data is stored encrypted on the server after the session
- Encryption applies only to text messages, not video streams
Correct answer: Data is encrypted from the sender's device and can only be decrypted by the intended recipient
End-to-end encryption ensures that only the communicating parties can decrypt and read the transmitted data, not intermediary servers.
Question 7: What is the primary purpose of a virtual waiting room in a telehealth platform?
- To allow the clinician to review patient records before joining
- To hold patients in a secure space until the clinician is ready without exposing them to other sessions (Correct answer)
- To test the patient's audio and video before the visit
- To collect patient copayment information
Correct answer: To hold patients in a secure space until the clinician is ready without exposing them to other sessions
A virtual waiting room queues patients in an isolated, secure space, protecting their privacy and preventing accidental exposure to other sessions.
