Sterile Storage and Distribution Flashcards

According to AAMI ST79, which of the following environmental conditions is MOST appropriate for the sterile storage area?

Answer: Temperature up to 75°F (24°C) and relative humidity not exceeding 70%

AAMI ST79 guidelines state that sterile storage areas should have a controlled temperature that can be as high as 75°F (24°C) and a relative humidity that should not exceed 70%. The other options are incorrect; 60-65°F is for the decontamination area, and negative air pressure is also a requirement for decontamination, not sterile storage, which requires positive pressure.

A technician is transporting a sterile instrument tray in a covered cart to the operating room. During transport, the cart is bumped, and the tray falls onto the floor. The outer wrap has a small tear. What is the appropriate action to take?

Answer: Return the tray to the Sterile Processing department for complete reprocessing.

Any sterile package that is dropped on the floor and shows visible damage, such as a tear, is considered contaminated. The integrity of the packaging has been compromised, and the item must be returned for complete reprocessing, including cleaning, inspection, and sterilization, to ensure patient safety.

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.

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.

When issuing sterile supplies, a technician should use the First-In, First-Out (FIFO) method. What is the primary reason for this practice?

Answer: To ensure that the oldest sterile supplies are used before they are potentially outdated.

The First-In, First-Out (FIFO) stock rotation method ensures that the items that were sterilized and placed on the shelf first are used first. This practice minimizes the chance of older items remaining on the shelf for extended periods, which is crucial for managing inventory effectively and using items well before any manufacturer-specified shelf life, even within an event-related sterility model.

A technician is preparing to transport sterile supplies from a central sterile processing department to a satellite clinic in a separate building. Which of the following is a critical requirement for this process?

Answer: Ensuring the transport vehicle is enclosed and protected from the elements.

When transporting sterile items, especially between facilities, they must be placed in a fully enclosed vehicle and in containers that protect them from environmental contamination, moisture, and physical damage. Open carts, personal vehicles without proper containment, and mixing sterile and contaminated items are all practices that would compromise sterility.
