TESTING


#1) All of the following statements about pitting (corrosion) of instruments are true except:

Can be caused by exposure to saline or bleach
Can be caused by prolonged exposure to blood
Can be caused by use of neutral pH detergents
Can allow for debris to get entrapped and is irreversable

#2) When cleaning surgical instruments it is important to first:

Place then in a washer sterilizer
Open and disassemble all instruments which can be disassembled
Place the instruments in a disinfectant
Flash sterilize them for decontamination

#3) When using an ultrasonic cleaner, it is important to:

Change the water daily
Use a high pH detergent
Perform the process in the Decontamination area
Process in the Prep and Assembly area

#4) Mixing of dissimilar metals in the liquid environment can cause:

Pitting and corrosion
Cavitation
A transfer of the metals
Dehydration

#5) A frequent cause of "black stains" on instruments is the result of exposure to:

Abrasives
Glutaraldehydes
Ammonia
Peracetic acid

#6) The use of demineralized or distilled water in cleaning can prevent rust spots caused by:

Copper in the water supply
Magnesium in the water supply
High iron content in the water supply
Calcium in the water supply

#7) When inspecting surgical instruments, what is the first step in the process?

Notify the O.R. of a broken/missing instrument
Replace the needed instrument on the set
Carefully check for cleanliness and proper working function
Assemble in proper order

#8) If a one-of-a-kind surgical instrument is noted to be broken, you should:

Send it for repair immediately
Notify the O.R. for advice how to proceed
Replace with a similar instrument
Keep it on the tray/set anyway

#9) When the Operating Room identifies an instrument needing repair, which of the following statements is not correct:

Should be decontaminated first then sent for repair
Should be properly identified as needing repair (safety pin, label, tag, etc.)
Should be sent to processing in the set as usual
Should obtain replacement for the instrument

#10) The best way to inspect surgical instruments is with the use of:

Good overhead lighting
Fluorescent lighting
Lighted magnifying lamps
Work table lighting

#11) All of the following statements about inspection of surgical instruments are true except:

All surgical instruments should be carefully inspected for cleanliness
All surgical instruments should be carefully inspected for proper working order
All surgical instruments should be inspected weekly
All surgical instruments should be inspected for proper assembly/parts

#12) When inspecting hinged surgical instruments, it is important to check for:

Proper alignment of the tips
Proper holding of the ratchets
Stiffness in the joints
All of the above

#13) Inspecting for chips in cutting blades/edges, stiffness in joints, and sharpness would be performed on the following group of surgical instruments:

Retractors
Hemostats
Sharps/scissors
Needle holders

#14) A major problem with chrome plated instruments is that:

They are more expensive
They are more difficult to cleany
They can chip and the plating can wear off
They can only be sterilized in ethylene oxide

#15) When cleaning instruments with multiple parts, it is important to:

Disassemble the instrument after cleaning so parts don't get lost during cleaning
Have the O.R. disassemble all instruments before sending to processing
Disassemble in Decontamination, before cleaning, keeping all parts together
Soak for several hours in an enzyme detergent

#16) Which of the following actions does not reflect inspection of needle holders?

That the tips hold a suture in place
That the instrument is clean
That the blades are sharp
That tungsten carbide inserts are in good condition (if gold plated handle)

#17) Some delicate surgical instruments can become magnetized during processing and use. All of the following statements about magnetized instruments are true except:

Some delicate surgical instruments can become magnetized by mixing dissimilar metals
Separation of dissimilar metals by wrapping techniques or separators may help prevent instruments from becoming magnetized
Once instruments become magnetized they must be discarded
Instruments which become magnetized need to be identified for the processing person

#18) All of the following statements about instrument lubricants are correct except:

It will protect the instrument from corrosion and spotting
It will keep moving parts working
All lubricants are penetrable by steam and ethylene oxide
May require mixing with distilled water

#19) Instrument lubrication should be performed:

In the Decontamination area after cleaning
In the Decontamination area after ultrasonic cleaning
In the Prep and Assembly area after proper decontamination
In the Prep and Assembly area before ultrasonic cleaning

#20) When assembling surgical instruments, all of the following statements are correct except:

Inspect all of the instruments for cleanliness
Inspect all instruments for proper working order
Place delicate items on bottom and heavier items on top
Specialty containers can prevent damage to delicate/microsurgical instruments

#21) Which types of instruments should be protected with tip protectors?

Hemostats, Retractors
Delicate instruments, sharps
Suction tips
Needle holders

#22) When using tip protectors, which of the following information from the manufacturer is not required for proper use?

If the tips are penetrable by steam, ethylene oxide or hydrogen peroxide gas plasma
If the tips are single use
If the tips are the least expensive available
If reusable, how to properly clean and number of times they can be used

#23) Acceptable methods for keeping surgical instruments open during sterilization include:

Metal stringers
Pins in pans/containers
Folded towel (floor or procedure trays)
All of the above

#24) When assembling surgical instrument sets/trays, accuracy in preparation is essential to the surgical team. Which of the following methods is not acceptable?

Recipe cards
Memory
Computer print outs
Inventory (count) sheets

#25) When storing sterile surgical instruments it is important that they be:

Stored in an open, unrestricted area
Stored on a flat shelf in an unrestricted area
Stored in a closed, restricted area on flat shelves
Stacked according to use
