CRNFA Surgical Instrumentation and Equipment 3

Question 1

A DeBakey tissue forceps is preferred over Adson tissue forceps when handling which type of tissue?

Accepted Answer

Delicate vascular or bowel tissue

Answer

DeBakey forceps have atraumatic fine serrations that grip delicate vascular or intestinal tissue without crushing, unlike the toothed Adson forceps.

Question 2

The CRNFA is using an argon beam coagulator (ABC). A key safety precaution specific to this device is:

Accepted Answer

Maintaining low gas flow to prevent pneumoperitoneum in laparoscopy

Answer

In laparoscopic procedures, argon gas from the ABC can rapidly increase intraabdominal pressure, causing pneumoperitoneum complications; gas evacuation must be managed carefully.

Question 3

Which classification system is used to categorize surgical instruments based on their degree of contact with sterile body tissues?

Accepted Answer

CDC Spaulding classification

Answer

The Spaulding classification (critical, semi-critical, non-critical) guides instrument reprocessing decisions based on the risk of infection associated with their use.

Question 4

A Balfour retractor with a center blade is most commonly used during which type of procedure?

Accepted Answer

Abdominal/pelvic surgery

Answer

The Balfour retractor is a self-retaining abdominal retractor with lateral blades and a central (bladder) blade used to hold the abdominal wall open during laparotomy.

Question 5

The CRNFA selects a TA (thoracoabdominal) stapler. Which statement BEST describes its function?

Accepted Answer

It places one or two rows of staples without dividing the tissue

Answer

The TA stapler applies one or two rows of staples to close tissue but does NOT cut, requiring the surgeon to manually transect the tissue afterward.
