Mixed Deck — All CBSPD Topics Flashcards

A technician is reprocessing surgical instruments used on a patient with suspected Creutzfeldt-Jakob Disease (CJD). Which of the following microorganisms is the cause of this disease and is known for its extreme resistance to standard sterilization processes?

Answer: Prion

Prions are proteinaceous infectious particles that cause transmissible spongiform encephalopathies (TSEs), like CJD. They are exceptionally resistant to conventional cleaning, disinfection, and sterilization methods, requiring special, extended protocols.

A root cause analysis (RCA) has been completed following a near-miss event where an unclean instrument was found in a tray post-sterilization. Which of the following would be considered the STRONGEST corrective action?

Answer: Modifying the workflow to include a lighted magnifying glass at the inspection station for all complex instruments.

The hierarchy of controls ranks corrective actions by effectiveness. The strongest actions are engineering or system fixes that make it difficult or impossible for the error to occur. Implementing a tool like a lighted magnifying glass is a system change that improves the ability to detect errors, making it a stronger intervention than relying solely on policy, training, or awareness campaigns, which are considered weaker actions.

How often should hand hygiene be performed by sterile processing technicians?

Answer: Before and after handling each instrument set or contaminated material

Hand hygiene should be performed before and after handling each instrument set or contaminated material to prevent the spread of infection and ensure a clean working environment.

After high-level disinfection, how should flexible endoscopes be rinsed?

Answer: With sterile water or filtered water

Sterile or filtered water must be used for the final rinse to prevent recontamination from microorganisms present in tap water.

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

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.

A sterile processing department is selecting a new high-level disinfectant for semi-critical devices. To ensure the product is legally approved for use as a disinfectant in the United States, the department manager must verify it has a registration number from which agency?

Answer: Environmental Protection Agency (EPA)

The EPA is responsible for regulating chemical disinfectants and sterilants used on non-critical environmental surfaces. These products must have an EPA registration number on their label, indicating they have been reviewed and approved for their specified claims. The FDA regulates liquid chemical sterilants used on critical and semi-critical devices.

Which inventory management method ensures that the oldest stock is used before newer stock, reducing the risk of expiration?

Answer: FIFO (First In, First Out)

FIFO ensures sterile supplies with earlier expiration dates are used first, maintaining product integrity and reducing waste.

Which of the following is a required practice for storing sterile items on shelving units in a sterile storage area?

Answer: Storing items at least 2 inches away from outside walls.

According to AAMI ST79 guidelines, sterile items should be stored at least 2 inches from outside walls to prevent contamination from potential condensation. Heavy items should be placed on middle shelves for ergonomic safety, items must never be on the floor, and a clearance of at least 18 inches from the ceiling or sprinkler heads is required.

Which step must be performed immediately after a flexible endoscope is removed from the patient?

Answer: Point-of-use wiping and flushing of channels

Point-of-use treatment — wiping the exterior and flushing channels with water or enzymatic solution — must occur immediately to prevent biofilm formation.

What is the primary purpose of the preparation and packaging process in sterile processing?

Answer: To ensure instruments are properly sterilized and remain sterile until use

The primary purpose of preparation and packaging is to create a sterile barrier that allows for effective sterilization and then maintains the sterility of instruments until they are opened for use. Proper packaging protects instruments from contamination during storage and transport. This critical step ensures that instruments remain sterile, safeguarding patient safety during medical procedures.

Which action should be taken if soiled instruments arrive in SPD without proper biohazard labeling?

Answer: Refuse acceptance until proper labeling is applied, and report the violation per facility policy

Proper biohazard labeling is an OSHA requirement; accepting unlabeled containers without addressing the violation could put staff at risk and represents a compliance failure.

A new flexible endoscope has just arrived in the sterile processing department. A technician, anxious to get it ready for a case, decides to use the same low-temperature sterilization cycle they use for a similar scope from a different manufacturer. This action violates a key principle mandated by which regulatory body?

Answer: The Food and Drug Administration (FDA)

The FDA regulates medical devices and requires manufacturers to provide specific, validated Instructions for Use (IFU) for each device. Deviating from the manufacturer's IFU is a violation of FDA regulations and can compromise patient safety by leading to improper reprocessing.

During an abdominal surgery, a large amount of irrigated fluid needs to be quickly evacuated from the surgical site without the suction line becoming clogged with tissue. Which suction tip is specifically designed for this purpose with its multiple perforations?

Answer: Poole Suction Tip

The Poole suction tip has a perforated outer sheath that allows it to aspirate large volumes of fluid from a cavity without being easily occluded by abdominal contents. The Yankauer is a general-purpose oral or pharyngeal suction tip, and the Frazier is a fine-tipped suction used for delicate procedures.

During the cleaning process, a technician notices a slimy, resistant layer on a complex surgical instrument that has been sitting for several hours before decontamination. This layer, which can protect microorganisms from disinfectants and sterilants, is known as:

Answer: A biofilm

A biofilm is a community of microorganisms that attach to a surface and are encased in a self-produced slimy, extracellular matrix. This matrix protects the embedded microbes, making them highly resistant to cleaning agents, disinfectants, and sterilants, which is why immediate point-of-use treatment and thorough cleaning are critical.

What is the purpose of using instrument protection devices, such as tip protectors or sleeves, during the sterilization process?

Answer: To protect delicate instrument tips and maintain their integrity

Instrument protection devices are used to safeguard delicate tips and other parts of instruments, preventing damage during handling, sterilization, and transport.

Which of the following actions best demonstrates accountability and professionalism for a sterile processing technician who discovers they made an error in assembling an instrument tray?

Answer: Immediately reporting the error to a supervisor and retrieving the tray if possible.

Accountability in sterile processing is critical for patient safety. The most professional and responsible action is to take immediate ownership of the error by reporting it through the proper channels so that corrective action can be taken before it impacts a patient.

Which of the following instruments is a double-action rongeur with a sharp, scooped tip, primarily used for cutting and removing small pieces of bone, especially from the vertebral column in spinal surgery?

Answer: Kerrison Rongeur

A Kerrison rongeur is a specialized, double-action instrument designed to remove small segments of bone, particularly in spinal and neurosurgical procedures like a laminectomy. A curette is used for scraping, an osteotome is a chisel used with a mallet for cutting or shaping bone, and a bone rasp is for smoothing bone.

A healthcare worker touches a contaminated bed rail and then, without performing hand hygiene, touches a patient's intravenous (IV) site, leading to an infection. This scenario is an example of which mode of transmission?

Answer: Indirect contact transmission

Indirect contact transmission occurs when a susceptible host comes into contact with a contaminated inanimate object, known as a fomite. In this case, the bed rail is the fomite that transfers pathogens from a source to the patient via the healthcare worker's hands.

What is the purpose of leak testing a flexible endoscope?

Answer: To detect internal damage that could allow fluid ingress

Leak testing identifies breaches in the endoscope's internal structure that could allow fluids to enter and damage components or harbor pathogens.

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?

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.
