Equipment Operation & Maintenance Flashcards

A specialist is performing a pre-use check on a ceiling track lift system. Which component failure would result in an immediate do-not-use determination?

Answer: A cracked or worn trolley wheel on the track

A cracked trolley wheel can cause the lift to derail under load, resulting in catastrophic fall risk for the client.

The recommended frequency for full clinical inspection of a custom power wheelchair by an assistive technology professional (ATP) is:

Answer: At least annually or when functional changes occur

Annual ATP inspection plus inspection at any functional change ensures the device continues to safely meet the evolving needs of the user.

A client who uses a ventilator at home experiences an unexpected alarm. The specialist's first response should be:

Answer: Follow the emergency action plan and notify the medical team immediately

Ventilator alarms signal potentially life-threatening conditions; the emergency action plan must be activated and medical personnel notified without delay.

Which factor most commonly causes power wheelchair joystick drift (the chair moves without user input)?

Answer: Joystick calibration offset due to damage or wear

Joystick drift typically occurs when the joystick's neutral position has shifted out of calibration due to physical wear or impact damage.

When a specialist is responsible for maintaining AAC devices used by multiple clients in a facility, cross-contamination between clients is best prevented by:

Answer: Wiping each device with EPA-registered disinfectant wipes between client uses

EPA-registered disinfectant wipes are effective against common pathogens and safe for electronics, making them the standard method for shared device decontamination.

A client's electronic hospital bed remote control no longer raises the head of the bed. The motor activates but nothing moves. The most likely cause is:

Answer: A broken actuator or drive cable between the motor and bed frame

When the motor runs but produces no movement, the mechanical linkage — actuator or drive cable — is the likely point of failure between motor and frame.

Under Medicare HCPCS billing requirements, durable medical equipment (DME) must be documented as 'medically necessary.' For a disability specialist, understanding this requirement primarily affects:

Answer: Justification documentation to support equipment acquisition for clients

Disability specialists must understand medical necessity documentation because inadequate justification causes insurance denials that delay or prevent clients from obtaining needed equipment.
