Surgical Prep & Instruments Quiz

1.

The very first thing to do when purchasing a new instrument is to:

A.

Sterilize the instrument
B.

Wash the instrument
C.

Read the manufacturer's instructions for processing.
D.

Place it in storage until needed.

Correct Answer
C. Read the manufacturer's instructions for processing.

Explanation
When purchasing a new instrument, it is important to read the manufacturer's instructions for processing. This step ensures that the instrument is properly cleaned, sterilized, and maintained according to the manufacturer's recommendations. By following these instructions, the user can ensure the instrument's longevity, functionality, and safety. Sterilizing and washing the instrument are also important steps, but without knowing the specific instructions provided by the manufacturer, these steps may not be done correctly or effectively. Placing the instrument in storage until needed is not the first thing to do as it overlooks the necessary steps for proper processing.

When labeling a wrapped set

A.

Label the set after it is wrapped.
B.

Write the name of the set on the autoclave tape before assembling the set.
C.

Use a magic marker
D.

Use an ink pen.

Correct Answer
B. Write the name of the set on the autoclave tape before assembling the set.

Explanation
The correct answer is to write the name of the set on the autoclave tape before assembling the set. This is because labeling the set after it is wrapped may result in the label becoming illegible or falling off during the wrapping process. Writing the name of the set on the autoclave tape before assembling ensures that the label is securely attached to the set and will remain readable throughout the sterilization process. Using a magic marker or an ink pen is not mentioned in the question and therefore not relevant to the correct answer.

Some enzymatic cleaners can be inactivated in temperatures that exceed:

A.

100 F
B.

120 F
C.

130 F
D.

140 F

Correct Answer
B. 120 F

Explanation
Some enzymatic cleaners can be inactivated in temperatures that exceed 120 F. This means that if the temperature goes beyond 120 F, the enzymes in the cleaner will no longer be effective in breaking down stains or odors. It is important to use enzymatic cleaners at the appropriate temperature to ensure their effectiveness in cleaning tasks.

When manually cleaning, it is recommended to wash items below the water to prevent

A.

Splashing
B.

Aerosolization of microbes
C.

Problems with rinsing
D.

Build-up of detergents

Correct Answer
B. Aerosolization of microbes

Explanation
When manually cleaning, it is recommended to wash items below the water to prevent aerosolization of microbes. This is because when items are washed above the water level, there is a higher chance of microbes being released into the air as tiny droplets or particles. These aerosolized microbes can then be inhaled or settle on nearby surfaces, leading to potential contamination and spread of diseases. Washing below the water level helps to minimize this risk and ensures a more effective and hygienic cleaning process.

Unless otherwise directed by the manufacturer, power equipment would best be cleaned

A.

In an ultrasonic cleaner
B.

In a mechanical washer/decontaminator
C.

Manually
D.

In a washer/sterilizer

Correct Answer
C. Manually

Explanation
The best way to clean power equipment, unless otherwise directed by the manufacturer, is to clean it manually. This means using traditional cleaning methods such as scrubbing, wiping, and rinsing by hand. This method allows for more control and precision in cleaning, ensuring that all areas of the equipment are thoroughly cleaned. Using an ultrasonic cleaner, mechanical washer/decontaminator, or washer/sterilizer may not be suitable for power equipment and could potentially damage or contaminate it.

The final step in the cleaning process is:

A.

Scrubbing
B.

Rinsing
C.

Inspection
D.

Disinfection

Correct Answer
D. Disinfection

Explanation
The final step in the cleaning process is disinfection. Once the surfaces have been scrubbed to remove dirt and grime, rinsed to remove any remaining cleaning agents, and inspected for cleanliness, the next step is to disinfect the surfaces. Disinfection involves using chemicals or other methods to kill or inactivate microorganisms, such as bacteria and viruses, that may be present on the surfaces. This step helps to ensure that the area is thoroughly sanitized and safe for use.

Instruments lubricant would best be applied

A.

In the decontamination area, after cleaning
B.

In the decontamination area, after disinfection
C.

In the prep/packaging area before assembly
D.

In the prep/packaging area after assembly

Correct Answer
C. In the prep/packaging area before assembly

Explanation
The correct answer is "in the prep/packaging area before assembly." Applying instrument lubricant in the prep/packaging area before assembly ensures that the instruments are properly lubricated and ready for use during the surgical procedure. This step is necessary to prevent damage to the instruments and ensure smooth operation. Applying lubricant after assembly may not be as effective as it may not reach all the necessary parts of the instrument. Additionally, applying lubricant in the decontamination area after cleaning or disinfection may introduce contaminants to the instruments, compromising their sterility.

Which of the following chemicals can destroy and corrode surgical instruments?

A.

Phenols and alcohol
B.

Alcohol and quats
C.

Enzymatic detergents and chlorine bleach
D.

Chlorine bleach and saline

Correct Answer
D. Chlorine bleach and saline

Explanation
Chlorine bleach and saline can destroy and corrode surgical instruments. Chlorine bleach is a strong oxidizing agent that can cause corrosion and damage to metal instruments. Saline, which is a solution of salt in water, can also cause corrosion over time if instruments are not properly cleaned and dried after use. Therefore, it is important to avoid using chlorine bleach and saline on surgical instruments to prevent damage and ensure their longevity.

If an instrument is found to be "stiff," the instrument should be

A.

Sprayed with mineral oil
B.

Sprayed with instrument lubricant
C.

Re-cleaned
D.

Placed on the set

Correct Answer
B. Sprayed with instrument lubricant

Explanation
When an instrument is described as "stiff," it means that it is not moving smoothly or easily. Spraying the instrument with instrument lubricant is the appropriate action to take in this situation. Instrument lubricant helps to reduce friction and allows the instrument to move more freely. This will help to restore the proper functioning of the instrument and ensure that it can be used effectively.

Scissors should e tested for sharpness

A.

Each time processed
B.

Weekly
C.

Every other week
D.

Monthy

Correct Answer
A. Each time processed

Explanation
The correct answer is "Each time processed" because scissors should be tested for sharpness every time they are used or processed. This is important to ensure that they are in good working condition and can effectively cut through materials. Regular testing helps to identify any dullness or damage, allowing for timely sharpening or replacement if needed. By testing the scissors each time they are processed, their sharpness can be maintained, ensuring optimal performance and safety.
