CSSD - Central Sterile Services Department Surgical Instrument Identification Questions and Answers — Questions and Answers
Question 1: A surgical tray for a delicate procedure involving fine tissue dissection arrives in the decontamination area. The technician identifies a pair of long, slender scissors with a longer shank-to-blade ratio. Which instrument is this most likely to be?
- Mayo scissors
- Potts scissors
- Metzenbaum scissors (Correct answer)
- Iris scissors
Correct answer: Metzenbaum scissors
Metzenbaum scissors are designed for cutting delicate tissues and for blunt dissection. They are characterized by their long shank and relatively short, fine blades, distinguishing them from the sturdier Mayo scissors which are used for cutting heavy tissues like fascia.
Question 2: During the assembly of a laminectomy set, a CSSD technician encounters an instrument with a long, thin shaft and a small, scooped, sharp tip designed for removing small pieces of bone, particularly in the spine. Which of the following instruments fits this description?
- Adson forceps
- Kerrison Rongeur (Correct answer)
- Weitlaner retractor
- Yankauer suction tip
Correct answer: Kerrison Rongeur
A Kerrison Rongeur is a specialized instrument used in neurosurgery and spinal surgery to remove small fragments of bone, often from the lamina of a vertebra. Its unique shape with a sharp, scooped tip and an angled or straight shaft is designed for this precise purpose.
Question 3: A CSSD technician is processing a suction instrument that includes a long metal tube, a thumbhole for controlling suction pressure, and a removable thin wire stylet for cleaning. This instrument is most commonly used for fine, delicate suction in confined areas. What is this instrument called?
- Poole suction tip
- Yankauer suction tip
- Baron suction tube
- Frazier suction tip (Correct answer)
Correct answer: Frazier suction tip
The Frazier suction tip is characterized by its thin, angled tube, a finger cut-off for controlling suction, and an included stylet to clear the lumen. It is used for precise suctioning in small or delicate areas like in neurosurgery, orthopedic, or ENT procedures.
Question 4: Which of the following components is NOT typically part of a Bookwalter retractor system?
- A table-mounted post and horizontal bar
- A segmented or solid ring
- A handheld, single-piece frame (Correct answer)
- Various retractor blades with ratchets
Correct answer: A handheld, single-piece frame
A Bookwalter retractor is a self-retaining, table-mounted system. Its key components include a post that clamps to the OR table, a horizontal bar, a ring that attaches to the bar, and various blades that are held in place by ratcheting mechanisms. It is not a handheld device.
Question 5: A surgeon requests 'heavy scissors' for cutting tough fascia. Which instrument should be selected from the instrument tray?
- Metzenbaum scissors
- Mayo scissors (Correct answer)
- Tenotomy scissors
- Iris scissors
Correct answer: Mayo scissors
Mayo scissors are heavy, robust scissors designed for cutting dense, tough tissues like fascia, muscle, and sutures. Their construction is much sturdier than Metzenbaum scissors, which are intended for delicate tissue.
Question 6: An instrument with finger rings, a box lock, shanks, and jaws is being inspected. The technician notes the jaws are serrated and the tip is curved. This general description fits many instruments. What is the primary function of an instrument identified as a 'hemostat'?
- Retracting tissue to expose the surgical site
- Grasping and holding needles for suturing
- Clamping blood vessels to control bleeding (Correct answer)
- Cutting sutures or delicate tissue
Correct answer: Clamping blood vessels to control bleeding
A hemostat, also known as a hemostatic forceps or artery forceps, is primarily designed to clamp and occlude blood vessels to control bleeding (hemostasis). While it shares structural similarities with other instruments, its specific function is vessel clamping.
