When checking the fit of a check socket during a quality assurance evaluation, total contact fit is confirmed by:
Answer: Verifying even pressure distribution with no air gaps at the distal end
Total contact is confirmed when the distal end has even pressure distribution with no visible or palpable air gaps, ensuring load is shared across the residual limb.
A technician notes that a patient's exoskeletal prosthetic shin section has a delaminating outer shell. The SAFEST immediate action is:
Answer: Remove the prosthesis from service and schedule repair before returning it to the patient
Delamination in a load-bearing exoskeletal component is a structural failure risk, so the prosthesis must be taken out of service until a proper repair or replacement is completed.
Which quality assurance document must be completed and retained in the patient's file when a prosthetic component is replaced under warranty?
Answer: A written repair note documenting the defective component, replacement part number, and date of service
A detailed written repair note with part numbers and dates must be retained for compliance, billing audit trails, and future clinical reference regardless of warranty status.
The purpose of a 'proof load' test in prosthetic structural testing is to:
Answer: Verify the device can sustain a specified load without permanent deformation
A proof load test applies a defined load (typically above typical use loads) and confirms no permanent deformation occurs, validating structural adequacy without destroying the component.
A patient complains that their prosthetic knee lock engages inconsistently. After inspection, the technician finds worn engagement teeth on the lock mechanism. The appropriate repair is:
Answer: Replace the lock mechanism with a new OEM component
Worn lock teeth cannot be reliably rehabilitated by filing or compound application; OEM component replacement restores the designed engagement geometry and safety margin.
When sanding a carbon fiber laminated socket for modifications, the technician MUST wear which personal protective equipment (PPE) as the minimum requirement?
Answer: N95 or P100 respirator and safety glasses
Carbon fiber particles are fine respirable hazards that require an N95 or P100 rated respirator; safety glasses protect against eye injury from particulates.
After completing a bench repair on a prosthetic elbow lock, the technician should verify function by:
Answer: Cycling the lock through full range of motion multiple times and confirming consistent engagement and release
Repeatedly cycling through full range confirms that engagement and release are reliable across the entire motion arc, not just in a single static position.
