  • 2. 

    An osteotome is

    • Used to cut or shave bone.

    • A retractor.

    • A hemostatic forceps.

    • Used to dissect soft tissue.

    Correct Answer
    A. Used to cut or shave bone.
    Explanation
    An osteotome is a surgical instrument specifically designed for cutting or shaving bone. It is commonly used in orthopedic procedures to remove or shape bone in order to correct deformities, create openings for implants, or facilitate bone healing. The sharp edge of the osteotome allows precise bone cutting, making it an essential tool in bone surgeries.

    Microgrind or supercut scissors are usually identified with a black handle.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Microgrind or supercut scissors are usually identified with a black handle. This means that most of the time, these types of scissors have a black handle.

  • 4. 

    During instrument manufacture the process of passivation helps build a protective chromium oxide layer on each instrument's surface.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Passivation is a process used during instrument manufacture to create a protective chromium oxide layer on the surface of each instrument. This layer helps prevent corrosion and extends the lifespan of the instrument. Therefore, the statement is true.

    The purpose of a suction stylet is to

    • Unclog the suction during surgery.

    • Clean the suction in the decontamination area.

    • Facilitate the sterilization process.

    • Provide a measuring guide for the surgeon.

    Correct Answer
    A. Unclog the suction during surgery.
    Explanation
    A suction stylet is a medical instrument used during surgery to remove debris or blockages from the suction system. It helps to maintain the effectiveness of the suction by unclogging it, ensuring that fluids and other materials can be efficiently removed from the surgical site. This is crucial for maintaining a clear field of vision and preventing complications during the procedure. The other options mentioned in the question (cleaning the suction, facilitating sterilization, providing a measuring guide) do not accurately describe the purpose of a suction stylet.

    After applying instrument identification tape, instruments should be autoclaved to help the tape bond to the instrument.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Autoclaving instruments after applying instrument identification tape helps the tape bond to the instrument. Autoclaving is a process that uses high temperature and pressure to sterilize instruments, and this heat and pressure can help the adhesive on the tape to securely bond with the instrument's surface. This ensures that the tape remains in place during the sterilization process and throughout subsequent use, preventing it from peeling off or becoming loose. Therefore, it is important to autoclave instruments after applying identification tape to ensure its effectiveness.

    Kerrison/laminectomy rongeurs should be tested using

    • Tissue paper.

    • A plastic dowel rod.

    • Rubber testing material.

    • An index card.

    Correct Answer
    A. An index card.
    Explanation
    Kerrison/laminectomy rongeurs are surgical instruments used for bone removal during spinal surgeries. These instruments have sharp jaws that need to be tested for sharpness. Testing them using tissue paper may not provide accurate results as the paper can tear easily. A plastic dowel rod or rubber testing material might not be suitable for testing the sharpness of the jaws. On the other hand, an index card is a sturdy material that can effectively test the sharpness of the rongeurs' jaws. Therefore, an index card is the most appropriate material for testing Kerrison/laminectomy rongeurs.

    Scissors with tungsten carbide cutting edges are usually identified by 

    • Black handles.

    • Silver handles.

    • Gold handles.

    • The letters "TC".

    Correct Answer
    A. Gold handles.
    Explanation
    Scissors with tungsten carbide cutting edges are usually identified by gold handles. This is because tungsten carbide is a very hard and durable material, making it ideal for scissors blades. The gold handles are used to indicate that the scissors have tungsten carbide cutting edges, distinguishing them from other types of scissors.

    Instrument marking tape should be wrapped approximately                     around the instrument.

    • 1.5 times

    • Two times

    • 2.5 times

    • Three times

    Correct Answer
    A. 1.5 times
    Explanation
    Instrument marking tape should be wrapped approximately 1.5 times around the instrument. This means that the tape should be wrapped around the instrument one and a half times. Wrapping the tape 1.5 times ensures that it is securely attached to the instrument and provides enough coverage for proper identification or marking.

    The place where the two parts of a ring handled instrument meet and pivot is called the box lock.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because the place where the two parts of a ring handled instrument meet and pivot is indeed called the box lock. This term is commonly used in the context of surgical instruments, such as scissors or forceps, where the two halves of the instrument are joined together at a central point allowing them to open and close. The box lock mechanism provides stability and precision in the instrument's movements, making it an essential component in many medical tools.

    The best way to clean a suction lumen is

    • Using running warm water.

    • Using the proper sized brush.

    • Soaking in an enzyme solution for three minutes.

    • Using the appropriate sylet.

    Correct Answer
    A. Using the proper sized brush.
    Explanation
    Using a proper sized brush is the best way to clean a suction lumen. This is because a brush allows for thorough cleaning and removal of debris from the lumen's surface. It can reach into the crevices and corners of the lumen, ensuring that it is properly cleaned. Running warm water alone may not be sufficient to remove all the debris, while soaking in an enzyme solution may be time-consuming and unnecessary for routine cleaning. Using an appropriate stylet is not mentioned as a method for cleaning a suction lumen.

    Stainless steel jaw needle holders last longer than tungsten carbide jaw needle holders.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Stainless steel jaw needle holders do not last longer than tungsten carbide jaw needle holders. Tungsten carbide is a harder and more durable material, making it more resistant to wear and tear. Therefore, tungsten carbide jaw needle holders are likely to have a longer lifespan compared to stainless steel jaw needle holders.

    Instruments are heat treated to give their surface a mirror (shiny) finish.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Instruments are not heat treated to give their surface a mirror finish. Heat treatment is a process used to alter the physical and mechanical properties of a material, such as its hardness or strength, through controlled heating and cooling. A mirror finish, on the other hand, is achieved through polishing or other surface treatment methods, not heat treatment. Therefore, the statement is false.

    To properly test the sharpness of scissors four inches or less use

    • Yellow test material.

    • Red test material.

    • An index cart.

    • Orange test material.

    Correct Answer
    A. Yellow test material.
    Explanation
    To properly test the sharpness of scissors four inches or less, yellow test material is used. This suggests that yellow test material is specifically designed to assess the sharpness of scissors within this size range. The other options (red test material, an index card, and orange test material) are not mentioned or recommended for testing the sharpness of scissors, indicating that they are not suitable for this purpose.

    Rate this question:

  • 15. 

    The part of a hemostat that locks and holds it in position is called the box lock.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The box lock is not the part of a hemostat that locks and holds it in position. The correct term for this part is the ratchet lock. Therefore, the statement is false.
