  1. Which retractor is specifically assembled on a tray for hip arthroplasty to retract the femoral head and expose the acetabulum?

    Answer: Hohmann retractor

    The Hohmann retractor is a curved, pointed retractor used in orthopedic procedures to lever and retract the femoral head and surrounding soft tissue.

  2. When assembling a neurosurgical craniotomy tray, which instrument is used to drill burr holes in the skull?

    Answer: Cranial perforator (Hudson brace or pneumatic drill)

    A cranial perforator or air-powered drill is used to create the initial burr holes through the skull before the bone flap is elevated.

  3. A CST discovers a wet package in the instrument set during tray assembly. The correct action is to:

    Answer: Consider it non-sterile and remove it from the field

    A wet sterile package is considered contaminated because moisture provides a pathway for microorganisms to penetrate the packaging material.

  4. Which instrument on a laparoscopic tray is used to create the initial pneumoperitoneum before trocar insertion?

    Answer: Veress needle

    The Veress needle is a spring-loaded needle inserted through the abdominal wall to insufflate CO2 and create the working space (pneumoperitoneum) for laparoscopic surgery.

  5. Which type of forceps included on a thoracic tray is used to grasp lung parenchyma without causing excessive trauma?

    Answer: Duval lung clamp

    Duval lung clamps have triangular fenestrated jaws that distribute pressure evenly, allowing atraumatic grasping of delicate lung tissue.

  6. After a procedure, instruments should be placed in which solution in the decontamination area before cleaning?

    Answer: Enzymatic detergent solution

    Enzymatic detergent solutions break down blood, protein, and bioburden on instruments, facilitating thorough cleaning before sterilization.

  7. When preparing a tray for a procedure using the electrosurgical unit (ESU), which accessory must be included on the sterile field?

    Answer: Bovie scratch pad (electrosurgical cleaner)

    A Bovie scratch pad is kept on the sterile field to clean coagulated tissue from the ESU tip between uses, maintaining effective energy delivery.
