CRCST Surgical Instrumentation 3

Question 1

Which instrument is specifically designed to grasp and excise small tissue samples for pathological examination?

Accepted Answer

Biopsy forceps or punch

Answer

Tissue retractor

Answer

Hemostat clamp

Answer

Needle holder

Question 2

A trocar is used in surgery primarily to:

Accepted Answer

Create a puncture opening through which cannulas or instruments can be inserted

Answer

Clamp bleeding vessels during an open procedure

Answer

Retract abdominal contents away from the operative site

Answer

Suture wound edges at the end of a laparoscopic case

Question 3

Microsurgical instruments differ from standard surgical instruments primarily because they are:

Accepted Answer

Significantly smaller and engineered for use under microscopic magnification

Answer

Constructed from disposable plastic rather than reusable metal

Answer

Designed exclusively for open cardiac surgery procedures

Answer

Single-use items that cannot undergo terminal sterilization

Question 4

What is the primary purpose of a bone curette?

Accepted Answer

To scoop and scrape bone tissue or soft tissue from a cavity

Answer

To make a precise cut through cortical bone

Answer

To hold bone fragments in alignment during fixation

Answer

To measure bone thickness during orthopedic procedures

Question 5

A malleable retractor is advantageous in surgery because it can be:

Accepted Answer

Bent by the surgeon to conform to the anatomical contours of the surgical site

Answer

Locked rigidly in position without any assistant support

Answer

Automatically adjusted to compensate for changes in tissue tension

Answer

Resterilized more rapidly than standard rigid retractors

Question 6

Surgical stapler instruments benefit the operative team primarily because they:

Accepted Answer

Rapidly place a line of staples to join tissue edges, significantly reducing closure time

Answer

Allow surgeons to cut tissue without the need for scissors

Answer

Remove previously placed sutures from a prior procedure

Answer

Clip blood vessels for easy laparoscopic removal

Question 7

Powered surgical instruments (e.g., drills, oscillating saws) require special processing considerations primarily because:

Accepted Answer

Their complex mechanisms, internal lumens, and components require specific disassembly and manufacturer-directed protocols

Answer

Their high cost makes them too valuable for routine sterilization cycles

Answer

They are classified as single-use items and cannot be reprocessed

Answer

They require cold sterilization only and cannot withstand steam autoclave temperatures
