  1. During a craniotomy, which powered instrument is used to cut through the skull?

    Answer: Craniotome (pneumatic or electric)

    A craniotome (also called a perforator/drill with a craniotome attachment) is used to make burr holes and cut the bone flap during a craniotomy.

  2. What is the purpose of a nerve hook during surgery?

    Answer: To gently retract or identify a nerve without damaging it

    A nerve hook is a blunt, curved instrument used to gently identify, separate, and retract delicate nerve structures during dissection.

  3. Which instrument would be used to grasp and manipulate the appendix during an appendectomy?

    Answer: Babcock clamp

    The Babcock clamp has atraumatic, fenestrated jaws that grasp hollow or tubular structures such as the appendix or bowel without crushing.

  4. Flash sterilization (immediate-use steam sterilization) should be used:

    Answer: Only when no other option exists and the item is needed immediately for an urgent case

    IUSS (flash sterilization) is acceptable only when items are needed urgently and there is no time for standard sterilization; it is not for routine use or implants.

  5. What is the proper sequence for passing a sharp instrument such as a loaded scalpel?

    Answer: Use the neutral zone (no-touch technique) to place and retrieve the instrument

    The neutral zone (hands-free technique) requires placing sharps in a designated area rather than hand-to-hand transfer to prevent needlestick injuries.

  6. Which vessel loop material is used to tag and retract delicate blood vessels or nerves during surgery?

    Answer: Silastic (silicone) vessel loop

    Silastic vessel loops are thin, pliable silicone bands used to gently identify, isolate, and retract delicate vessels and nerves without causing damage.

  7. Which instrument is used to dilate the cervix during a dilation and curettage (D&C) procedure?

    Answer: Both Hegar and Pratt dilators

    Both Hegar and Pratt dilators are cervical dilators used progressively from small to large to open the cervical os before uterine curettage.
