NCCT Equip Sterilization & Maintenance Questions with
Detailed Verified Answers
The surgical technologist has just received an unsterile femoral implant tray. Which of the following
is the proper protocol for sterilizing the implant tray? Ans: ✓ ✓ ✓ prevacuum sterilization for 29
min sterilization and 40 min drying time at 270 - 275 degrees Fahrenheit with a biological indicator.
Since the item to be sterilized is an implant tray, it must be sterilized for 29 minutes at 270-275
degrees with a biological indicator. Three minutes would not be an appropriate time to flash an
implant. Biological monitors are required to be placed in with the sterilized load for any implantable
device.
Which of the following is the first test of the day performed before using an autoclave? Ans: ✓ ✓ ✓
Bowie-Dick test
Which of the following daily tests must be performed on the pre-vacuum sterilizer before using it?
Ans: ✓ ✓ ✓ Bowie-Dick
Which of the following should the surgical technologist use to cool instruments after removing
them from a steam autoclave? Ans: ✓ ✓ ✓ sterile water
What is the minimum exposure time in a flash sterilizer for unwrapped instruments? Ans: ✓ ✓ ✓ 3
minutes
Which of the following is the correct temperature for flash sterilizer operation? Ans: ✓ ✓ ✓ 132°C
(270°F)
Which of the following are the three factors needed to achieve steam sterilization? Ans: ✓ ✓ ✓
exposure time, temperature, moisture

The five factors that are critical for a correct sterilization process include proper time, contact of the
sterilant, temperature, moisture, and pressure. There are exceptions to drying time, such as steam
sterilizing an instrument for immediate use. Radiation is important when using ionizing radiation as
a sterilization process.
Which of the following is the proper temperature and time that the chamber of a steam sterilizer
must reach in order to ensure that all spores have been eliminated? Ans: ✓ ✓ ✓ 270° F for 4
minutes
While transporting a specimen to the lab, the surgical technologist dropped the formalin filled
specimen container. Where can the surgical technologist find the instructions for clean up? Ans: ✓
✓ ✓ MSDS (material safety data sheet)
The decontamination, cleaning, and sterilization of endoscopes includes which of the following
guidelines? (Select the three (3) correct answers.) Ans: ✓ ✓ ✓ Do not rinse with 70% alcohol., Use
glutaraldehyde., Use enzymatic detergent.
The Sterrad sterilization system most commonly uses which of the following chemical solutions?
Ans: ✓ ✓ ✓ hydrogen peroxide
Which of the following is used to achieve high level disinfection with a minimum exposure time of
20 to 45 minutes? Ans: ✓ ✓ ✓ glutaraldehyde
Glutaraldehyde is a high-level disinfectant, and has a minimum exposure time of 20 minutes: it is
used as a sterilant. Chlorine bleach, hydrogen peroxide and iodine, and iodophors are used as
cleaners or aseptic cleaners but are not high level disinfectants.
The process of eliminating many or all pathogenic organisms, except bacterial spores, from
inanimate objects is the process of Ans: ✓ ✓ ✓ disinfection
Disinfectants are not capable of killing spores or certain viruses: it is an intermediate level
disinfectant and is used on inanimate objects, such as operating room furniture and floors.
Sterilization gets rid of all spores and living micro-organisms. Sanitation is the process of making
