  1. When grinding or sanding prosthetic components, which PPE is MOST critical to prevent respiratory harm?

    Answer: N95 respirator or dust mask

    Grinding generates fine particulate dust that can cause respiratory damage, making an N95 respirator the most critical protective equipment.

  2. A prosthetic technician notices a crack in their nitrile glove mid-procedure. What is the correct action?

    Answer: Stop, remove gloves, perform hand hygiene, and don new gloves

    A compromised glove barrier must be replaced immediately; the technician must remove the gloves, perform hand hygiene, and don a new pair.

  3. Which disinfectant concentration of isopropyl alcohol is most effective for surface decontamination in a prosthetics lab?

    Answer: 70%

    70% isopropyl alcohol is the most effective concentration because some water is needed to facilitate protein denaturation in microorganisms.

  4. OSHA's Bloodborne Pathogen Standard (29 CFR 1910.1030) requires employers to offer which vaccination to exposed workers at no cost?

    Answer: Hepatitis B

    OSHA mandates that employers offer the Hepatitis B vaccine series free of charge to workers with occupational exposure to bloodborne pathogens.

  5. After trimming a patient's residual limb cast, the workspace is contaminated with skin cells and debris. The FIRST step is to:

    Answer: Remove gross debris with a disposable cloth, then disinfect

    Gross debris must be removed before disinfection because organic material can inactivate disinfectants and prevent effective kill.

  6. Which class of fire extinguisher should be used for an electrical fire in a prosthetics fabrication lab?

    Answer: Class C

    Class C extinguishers are designed for energized electrical equipment fires because they use non-conductive extinguishing agents.

  7. When autoclaving metal fabrication tools, the minimum standard sterilization cycle for a gravity displacement autoclave is typically:

    Answer: 121°C for 15 minutes at 15 psi

    The standard gravity displacement autoclave cycle is 121°C (250°F) for a minimum of 15 minutes at 15 psi to achieve sterilization.
