CTC Equipment Operation & Maintenance 2 — Questions and Answers
Question 1: A telehealth cart's pan-tilt-zoom camera is producing a blurry image during a patient consultation. What is the FIRST troubleshooting step?
- Replace the camera unit immediately
- Clean the camera lens with a microfiber cloth (Correct answer)
- Restart the entire telehealth system
- Increase the network bandwidth allocation
Correct answer: Clean the camera lens with a microfiber cloth
A dirty or smudged lens is the most common and easily corrected cause of blurry PTZ camera images.
Question 2: Which standard governs the electrical safety testing requirements for medical-grade telehealth equipment used in clinical settings?
- IEC 60601-1 (Correct answer)
- IEEE 802.11ac
- HIPAA Security Rule §164.312
- ISO 9001:2015
Correct answer: IEC 60601-1
IEC 60601-1 is the international standard specifying safety and essential performance requirements for medical electrical equipment.
Question 3: A remote patient monitoring device is sending erratic readings. After confirming the patient is stable, what should the telehealth coordinator check NEXT?
- Order a replacement device
- Verify the device's sensor placement and skin contact (Correct answer)
- Contact the device manufacturer immediately
- Notify the billing department of a potential equipment failure
Correct answer: Verify the device's sensor placement and skin contact
Improper sensor placement or poor skin contact is the most frequent cause of erratic biometric readings from wearable RPM devices.
Question 4: How often should telehealth peripheral devices such as otoscopes and stethoscopes undergo preventive maintenance inspections?
- Only when a malfunction is reported
- Monthly at minimum, or per manufacturer guidelines (Correct answer)
- Once per year during the annual compliance review
- Every five years per FDA regulations
Correct answer: Monthly at minimum, or per manufacturer guidelines
Monthly inspections or adherence to manufacturer-specified intervals ensure peripherals remain accurate and safe for clinical use.
Question 5: A telehealth workstation displays a 'hardware not recognized' error when a USB-connected digital stethoscope is plugged in. What is the most likely cause?
- The stethoscope is incompatible with telehealth software
- A missing or outdated device driver on the workstation (Correct answer)
- The USB port is providing insufficient power
- The device requires Bluetooth instead of USB
Correct answer: A missing or outdated device driver on the workstation
Missing or outdated drivers are the most common reason a USB peripheral is not recognized by the operating system.
Question 6: When decommissioning a telehealth cart that stored Protected Health Information (PHI), what must be done before disposal?
- Remove the camera and microphone modules only
- Perform NIST SP 800-88 compliant data sanitization on all storage media (Correct answer)
- Return the cart to the vendor for processing
- Delete visible patient files from the desktop
Correct answer: Perform NIST SP 800-88 compliant data sanitization on all storage media
NIST SP 800-88 provides guidelines for media sanitization to ensure PHI cannot be recovered from decommissioned devices.
Question 7: A telehealth coordinator notices that the room lighting makes it difficult for the remote clinician to assess a patient's skin color accurately. What is the best immediate solution?
- Upgrade to a higher-resolution camera
- Adjust the room lighting to ensure even, adequate illumination behind and around the patient (Correct answer)
- Ask the clinician to increase their monitor brightness
- Switch to a wide-angle lens attachment
Correct answer: Adjust the room lighting to ensure even, adequate illumination behind and around the patient
Proper ambient lighting around the patient is the most effective way to ensure accurate color representation without hardware changes.
