Biohazard symbol and/or the word 'biohazard' must be present (Correct answer)
No labeling needed if the container is red
A list of all instruments inside

Correct answer: Biohazard symbol and/or the word 'biohazard' must be present

OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030) requires that containers holding potentially infectious materials be labeled with the biohazard symbol.

Question 58: Which inventory system continuously tracks stock levels in real time and updates automatically when items are added or removed?

Manual counting system
Consignment inventory system
Perpetual inventory system (Correct answer)
Periodic inventory system

Correct answer: Perpetual inventory system

A perpetual inventory system uses software and scanning technology to continuously update stock levels, providing an accurate real-time picture of inventory.

Question 59: A positive biological indicator (BI) is reported from a steam sterilization load that has already been distributed. What is the FIRST step the sterile processing department should take?

Initiate a recall of all items processed in that load and all loads back to the last negative BI. (Correct answer)
Take the sterilizer out of service for maintenance.
Document the failure and re-sterilize the next load with two BIs.
Notify the infection control department and wait for instructions.

Correct answer: Initiate a recall of all items processed in that load and all loads back to the last negative BI.

In the event of a positive BI, the immediate priority is patient safety. A recall must be initiated to retrieve all potentially non-sterile items from the suspect load and any subsequent loads processed since the last known good cycle (negative BI). This action prevents the use of compromised instruments on patients. Other steps like taking the sterilizer out of service and notifying other departments follow the initiation of the recall.

Question 60: A sterile processing technician is packaging a tray of heavy orthopedic instruments. According to ANSI/AAMI ST77, what is the maximum recommended weight for a wrapped instrument tray, including the container and all contents?

Question 61: The modern concept that a sterile item is considered sterile until an event occurs to compromise its packaging is known as:

Time-related sterility
Aseptic presentation
Event-related sterility (Correct answer)
Terminal sterilization

Correct answer: Event-related sterility

Event-related sterility is the principle that the shelf life of a sterilized item is dependent on events that could compromise the package integrity, such as tearing, moisture penetration, or excessive handling, rather than a fixed expiration date.

Question 62: What is the correct traffic flow principle that should be maintained in a sterile processing department?

Items can move freely between zones if they are wrapped
Traffic flow only matters in the OR, not in SPD
Decontamination area and clean assembly area can share the same hallway if staff change gloves

Correct answer: To reduce the presence of pathogens on surfaces and equipment

Environmental cleaning in the sterile processing department is essential to reduce the presence of pathogens on surfaces and equipment, thereby preventing the spread of infection.

Question 120: A surgeon is performing a delicate dissection of soft, deep tissue. Which of the following scissors, characterized by their long shanks and short, fine blades, would be the most appropriate choice for this task?

Potts-Smith Scissors
Bandage Scissors
Mayo Scissors
Metzenbaum Scissors (Correct answer)

Correct answer: Metzenbaum Scissors

Metzenbaum scissors are designed for fine, delicate dissection and cutting of soft tissues. Their long, slender shanks allow surgeons to reach into deeper cavities while the short blades provide precision. Mayo scissors are heavier and used for cutting tougher tissues like fascia or sutures. Bandage and Potts-Smith scissors serve other specialized purposes.

Question 121: During an Ethylene Oxide (EtO) sterilization cycle, which parameter is critical for allowing the gas to effectively alkylate the microorganisms' DNA?

Deep vacuum
Low temperature
Bright lighting
Proper humidity (Correct answer)

Correct answer: Proper humidity

The four essential parameters for Ethylene Oxide (EtO) sterilization are gas concentration, temperature, exposure time, and relative humidity. Humidity is critical because water molecules act as a carrier, transporting the EtO molecules to the reactive sites on the microorganisms, thus enabling the alkylation process that disrupts their DNA and kills them.

Question 122: What is the recommended advance notice facilities should require from vendors for loaner instrument delivery?

At least 24 hours before the scheduled procedure to allow adequate processing time (Correct answer)
72 hours before the procedure
One week in advance
Same-day delivery is acceptable

Correct answer: At least 24 hours before the scheduled procedure to allow adequate processing time

Professional guidelines recommend loaner instruments arrive at least 24 hours before the procedure to allow thorough inspection, decontamination, and sterilization.

Question 123: Which of the following instruments is a self-retaining retractor, meaning it utilizes a locking mechanism to hold tissue apart without being continuously held by a person?

Richardson Retractor
Weitlaner Retractor (Correct answer)
Army-Navy Retractor
Deaver Retractor

Correct answer: Weitlaner Retractor

The Weitlaner retractor has a ratchet mechanism that locks its prongs in an open position, making it self-retaining. Deaver, Army-Navy, and Richardson retractors are all handheld instruments that require continuous manual force to maintain retraction.

Question 124: What is an Automated Endoscope Reprocessor (AER) used for?

Performing only leak testing
Replacing manual cleaning steps entirely
Automating the HLD rinse and drying cycles for flexible endoscopes (Correct answer)
Sterilizing rigid scopes via steam

Correct answer: Automating the HLD rinse and drying cycles for flexible endoscopes

An AER automates the high-level disinfection, rinsing, and sometimes drying cycles, but does NOT replace the mandatory manual cleaning step.

Question 125: A new sterile processing technician is assembling an instrument set in a rigid container system. Which of the following actions is required before sterilizing the container?

Applying lubrication to the container's gasket.
Placing a Bowie-Dick test sheet inside the container.
Wrapping the entire rigid container in two layers of non-woven wrap.
Ensuring the internal chemical indicator is placed in the most challenging area. (Correct answer)

Correct answer: Ensuring the internal chemical indicator is placed in the most challenging area.

An internal chemical indicator must be placed in every package to verify that the sterilant has penetrated to the point of placement. According to AAMI ST79, it should be placed in the area of the tray or container that is considered most difficult for the sterilant to reach, often the geometric center.
