CTP Telepresence and Technology 4 — Questions and Answers
Question 1: A telehealth clinician is seeing a patient in a rural area using a mobile device on a cellular network. Call quality suddenly drops. What should be done first?
- End the session and reschedule for a phone-only visit
- Ask the patient to move to a location with stronger cellular signal or connect to Wi-Fi (Correct answer)
- Switch to a lower-bandwidth communication tool such as secure messaging
- Call the patient's mobile carrier to report an outage
Correct answer: Ask the patient to move to a location with stronger cellular signal or connect to Wi-Fi
Asking the patient to find a stronger signal or connect to Wi-Fi is the quickest first step to restore adequate connection quality.
Question 2: Which element of telehealth room setup most directly affects a patient's perception of professionalism and trust?
- The clinician's typing speed during the session
- A clean, uncluttered background behind the clinician (Correct answer)
- The size of the clinician's monitor
- Whether the clinician uses a wired or wireless keyboard
Correct answer: A clean, uncluttered background behind the clinician
A clean, professional background minimizes distractions and signals to the patient that the clinician takes the encounter seriously.
Question 3: Remote patient monitoring (RPM) devices transmit biometric data to a clinician. Which technology standard is most commonly used for short-range wireless transmission from these devices?
- 4G LTE
- Bluetooth (Correct answer)
- Wi-Fi 6
- Ethernet
Correct answer: Bluetooth
Bluetooth is the most widely used short-range wireless standard for connecting RPM devices such as glucose meters, blood pressure cuffs, and pulse oximeters to a gateway or smartphone.
Question 4: A telehealth provider wants to ensure their platform meets ADA accessibility standards. Which feature is MOST important for patients who are Deaf or hard of hearing?
- High-resolution camera support
- Real-time captioning or ASL interpreter integration (Correct answer)
- Touch-screen compatibility
- Adjustable font size in the chat window
Correct answer: Real-time captioning or ASL interpreter integration
Real-time captioning or ASL interpreter integration directly addresses the communication access needs of Deaf and hard-of-hearing patients.
Question 5: What does 'latency' mean in the context of telehealth video communication?
- The number of frames displayed per second
- The delay between when data is sent and when it is received (Correct answer)
- The resolution quality of the video stream
- The encryption processing time for PHI
Correct answer: The delay between when data is sent and when it is received
Latency is the time delay in data transmission; high latency causes noticeable lag in audio and video during a telehealth session.
Question 6: A clinician is evaluating two telehealth platforms. Platform A uses 128-bit encryption and Platform B uses 256-bit AES encryption. Which platform offers stronger data protection?
- Platform A, because lower-bit encryption is faster and more efficient
- Platform B, because 256-bit AES encryption provides a significantly larger key space (Correct answer)
- They are equivalent because both meet HIPAA minimum standards
- Platform A, because 128-bit is the current industry gold standard
Correct answer: Platform B, because 256-bit AES encryption provides a significantly larger key space
256-bit AES encryption offers a vastly larger key space than 128-bit, making it computationally infeasible to brute-force and providing stronger protection for PHI.
Question 7: Which of the following best describes a 'hub-and-spoke' telehealth model?
- Multiple clinicians connect to a single patient from different locations simultaneously
- A central specialist hub provides remote consultations to patients located at distributed spoke sites (Correct answer)
- A patient uses a mobile app to connect directly to any available clinician
- An AI hub triages patients before routing them to human clinicians
Correct answer: A central specialist hub provides remote consultations to patients located at distributed spoke sites
In the hub-and-spoke model, a central hub facility (specialist center) connects remotely to peripheral spoke sites (rural clinics, hospitals) to deliver specialty care.
