TESTING


#1) The most important factor in the life of a surgical instrument is:

Where the instrument was manufactured
Cost of the instrument
Proper care and handling
Duplicating inventory

#2) There are several acceptable methods for instrument identification (marking). Which of the following is NOT acceptable?

Chemical etching
Instrument marking tape
Vibro engraving
"Dipped" handles

#3) When using instrument marking tape, it is important to:

Follow the manufacturer's directions for correct application
Determine if the tape is steam and ethylene oxide penetrable
Check the condition of the tape frequently for chipping, flaking
All of the above

#4) When etching surgical instruments, the etching should be located:

On the handle
On the box lock
On the shanks
Anywhere it will be visible

#5) There are three types of instrument finishes. Which of the following is NOT one?

Bright or shiny
Dull or satin
Demagnetized
Ebony

#6) The process in which instruments are placed in a diluted acid bath containing chemicals to make the instrument "corrosion resistant" is called:

Sterilization
Chemical disinfection
Passivation
Polymerization

#7) The basic parts of a surgical instrument:

The jaws, shanks, ratchets and box lock
The jaws, box lock, ratchets and handles
The box lock, shanks, ratchets and handles
The jaws, box lock, shanks, ratchets and handles

#8) The most difficult part of an instrument to keep clean is the:

Jaws
Ratchet
Box Lock
Shank

#9) Which of the following groups of instruments are examples of hemostats?

Mayo, Metzenbaum, Iris
Adson, Russian, Dressing
Mosquito, Crile, Kelly
Poole, Frazier, Yankauer

#10) Which of the following groups of instruments are examples of scissors?

Mayo, Metzenbaum, Iris
Adson, Russian, Dressing
Mosquito, Crile, Kelly
Poole, Frazier, Yankauer

#11) Which of the following groups of instruments are examples of finger forceps?

Mayo, Metzenbaum, Iris
Adson, Russian, Dressing
Mosquito, Crile, Kelly
Poole, Frazier, Yankauer

#12) One advantage to tungsten carbide inserts on needle holders is that:

They make the surgery go faster
They can be replaced if they wear down
They are easier to clean
They will never wear out

#13) Suture scissors can also be used to cut:

Tissue
Tape
Tubings
None of the above

#14) Instruments with tungsten carbide inserts (needle holders) or blades (scissors) can be identified by:

Special etching on the shanks
Gold plated handles
Both of the above
Special etching on the handle

#15) The three types of scissors used for tissue dissection are:

Iris, Kelly, Tenotomy
Metzenbaum, Mayo, Suture
Suture, Mayo, Metzenbaum
Mayo, Metzenbaum, Iris

#16) All of the following statements about retractors are true except:

Finger or hand held retractors are mainly used in shallow or narrow areas
Retractors can have sharp, dull, blade or wire loop ends
Retractors are used to keep tissue and organs out of the way during the surgery
Self-retaining retractors are held in place by an assistant during surgery

#17) Which of the following groups of instruments are examples or retractors?

Weitlaner, Kelly, Metzenbaum
Richardson, Poole, Army-Navy
Army-Navy, Richardson, Sean
Mayo-Hegar, Crile, Yankauer

#18) An example of a malleable retractor is a :

O'Connor-O'Sullivan
Balfour
Ribbon
Weitlaner

#19) The first step in the sterilization process is:

Proper disinfection
Proper packaging
Proper cleaning
Proper assembly

#20) Immediately after use, surgical instruments should:

Be placed in a basin of saline
Be placed in a solution of hydrogen peroxide
Be placed in sterile distilled water
Be placed in a high alkaline detergent

#21) The pH scale measures:

The density of materials
The porosity of materials
The acidity or alkalinity of items
The concentration of liquids

#22) The preferred pH for detergents used to clean surgical instruments:

4.5 to 6.0
7.0 to 7.8
2.0 to 4.9
8.2 to 11.1

#23) The use of excessively high or low pH detergents can:

Help clean instruments more effectively
Eliminate the need for ultrasonic cleaning
Remove the passivation layer from surgical instruments
Add additional passivation layers to the surgical instruments

#24) All of the following statements about cleaning are true except:

Detergents should be measured carefully following manufacturer's instructions
Doubling the concentration of detergents will make cleaning easier
The type of water used may affect spotting and staining of instruments
Sinks or basins used for manual cleaning of instruments need to be measured for capacity

#25) Which of the following products are recommended for use in cleaning surgical instruments?

Liquid soaps
Neutral pH detergents
Abrasives
Bleach
