Equipment Operation & Maintenance Flashcards

A remote patient monitoring hub loses its cellular connection in a rural area. Which backup connectivity option should a telehealth coordinator have pre-arranged for such scenarios?

Answer: A secondary SIM card from a different carrier or a satellite connectivity option

A backup connectivity plan using a different carrier or satellite ensures continuity of monitoring for patients in areas with unreliable primary networks.

During a telehealth visit, the remote clinician reports that the digital exam camera image appears green-tinted. What is the most likely cause?

Answer: The camera's white balance is set incorrectly

Incorrect white balance settings cause color casts — a green tint typically indicates the camera is compensating for the wrong lighting type.

What is the recommended minimum display resolution for a telehealth workstation monitor used for dermatology teleconsultations?

Answer: 1920x1080 (Full HD) or higher

Dermatology requires high-resolution displays to assess fine skin details accurately; Full HD (1080p) or higher is the recommended minimum standard.

A telehealth coordinator is documenting a preventive maintenance visit on a videoconferencing unit. Which item should be included in the maintenance log?

Answer: Date, technician name, tests performed, results, and any components replaced or adjusted

Complete maintenance logs must include date, technician, procedures performed, findings, and any corrective actions to ensure traceability and compliance.

Which of the following is a key indicator that a telehealth cart's PTZ camera motor is failing?

Answer: Grinding noises during pan/tilt movements and failure to reach commanded positions

Mechanical grinding and positional inaccuracy during pan/tilt operation are classic signs of motor wear or gear damage in PTZ cameras.

A telehealth coordinator discovers that a vendor-supplied remote monitoring device has been recalled by the FDA. What is the immediate required action?

Answer: Immediately discontinue use of the recalled device and notify affected patients and clinicians

FDA recalls require immediate cessation of use and prompt notification to all stakeholders to prevent patient harm.

What is the purpose of performing a 'loopback test' on telehealth audio equipment?

Answer: To verify that the microphone and speaker are both functioning correctly by routing the microphone output back to the speaker

A loopback test routes the microphone signal directly to the speaker output, allowing a technician to confirm the entire local audio chain is working.
