  1. Which of the following instrument sets would be assembled for a cesarean section (C-section)?

    Answer: OB tray with uterine clamps and bladder retractors

    A C-section tray includes specialized instruments like DeLee retractors for bladder retraction and Pennington clamps for uterine edge control.

  2. A Weitlaner retractor differs from a handheld retractor in that it:

    Answer: Is self-retaining and maintains position without an assistant

    Weitlaner retractors are self-retaining because their ratcheted arms lock open to hold tissue without manual assistance.

  3. When loading a scalpel blade onto a handle, the CST should use which technique?

    OSHA guidelines require using an instrument such as a needle holder to load and unload scalpel blades to prevent sharps injuries.

  4. Which type of scissors on a general surgery tray is designed for cutting suture?

    Answer: Straight Mayo scissors

    Straight Mayo scissors have heavy, blunt blades designed for cutting suture and heavy tissue, distinguishing them from Metzenbaum scissors used for delicate dissection.

  5. A Bookwalter retractor system is most commonly assembled for which type of procedure?

    Answer: Deep pelvic or abdominal procedures requiring prolonged retraction

    The Bookwalter is a table-mounted ring retractor system that provides stable, hands-free retraction for prolonged deep abdominal or pelvic surgery.

  6. Which instrument on a vascular tray is used to remove thrombus from the lumen of a blood vessel?

    Answer: Fogarty balloon catheter

    The Fogarty balloon catheter is inserted past the clot, inflated, and withdrawn to mechanically extract thrombus from vessels.

  7. When assembling a tray for a procedure requiring magnification, the scrub technician should include which type of instruments?

    Answer: Micro-instruments with smooth, fine-tipped jaws

    Microsurgery requires delicate micro-instruments with fine tips capable of handling tiny structures without crushing or tearing.
