  1. What is the function of the platen pressure gauge on a hydraulic press used in prosthetics?

    Answer: It indicates the force being applied to the workpiece

    The pressure gauge shows the force applied to the workpiece, allowing the technician to stay within safe limits for the material being formed.

  2. A vacuum-forming machine fails to achieve the target vacuum level. Which component should be checked first?

    Answer: The vacuum pump oil level and intake filter

    Low vacuum is most often caused by a dirty intake filter or low pump oil, both of which reduce pump efficiency.

  3. Which procedure is used to verify that a torque screwdriver is calibrated correctly before use on prosthetic components?

    Answer: Compare its setting to a reference torque standard or calibrated tester

    Calibration is verified by testing against a known reference torque standard to ensure accurate fastener tightening.

  4. When using a rotary tool (Dremel-type) for finishing carbon fiber prosthetic components, which bit type is most appropriate?

    Answer: Diamond-coated or carbide burr

    Diamond-coated or carbide burr bits are required for carbon fiber because its abrasive nature dulls standard steel quickly.

  5. After completing fiberglass lamination, how should the mixing cups and brushes be disposed of in a compliant US prosthetic lab?

    Answer: Treated as hazardous waste per OSHA and local regulations

    Uncured or partially cured resin waste is hazardous and must be disposed of according to OSHA and local hazardous waste regulations.

  6. What maintenance step prevents rust formation inside the air tank of a compressor used for prosthetic lab pneumatic tools?

    Answer: Draining condensate from the tank drain valve regularly

    Moisture condenses inside air tanks and must be drained regularly to prevent corrosion and contamination of air tools.

  7. Which measurement tool is used to verify the bore diameter of a prosthetic socket mounting hole to ensure correct fit of a pyramid adapter?

    Answer: Digital caliper set to inside measurement mode

    A digital caliper in inside measurement mode accurately measures bore diameters to verify compatibility with pyramid adapter specifications.
