Sterile Storage, Inventory Management, and Distribution Systems Flashcards

What are the generally accepted temperature and humidity ranges for a sterile storage area?

Answer: Not to exceed 75°F (24°C) and humidity between 30-60%

ANSI/AAMI ST79 recommends that sterile storage areas be maintained at a temperature not exceeding 75°F (24°C) and relative humidity between 30% and 60%. These specific conditions are crucial for preventing microbial growth and maintaining the integrity of sterile packaging materials.

Which of the following is a requirement for shelving used in sterile storage areas?

Answer: Both B and C are correct.

Sterile storage shelving must be non-porous and easy to clean. The bottom shelf must be solid to protect items from floor contamination and cleaning activities, and be 8-10 inches off the floor. A clearance of at least 18 inches from the ceiling is required to allow for proper air circulation and fire sprinkler function.

The principle of "First In, First Out" (FIFO) in sterile storage ensures that:

Answer: The oldest sterile supplies are used first, minimizing the potential for outdated items.

FIFO is a critical stock rotation method where the oldest supplies (those that were "in" first) are used first ("out" first). This practice helps ensure that items do not expire before use and maintains the efficacy of the sterile supply inventory by preventing items from sitting on shelves for extended periods.

The concept of "event-related sterility" means that an item is considered sterile until:

Answer: A specific event occurs that compromises the package's integrity.

Event-related sterility is the modern standard, replacing time-based expiration dates. It posits that a product remains sterile as long as the packaging is not compromised by events like tearing, getting wet, being crushed, or excessive handling.

A PAR-level inventory system is best described as:

Answer: A system where a predetermined quantity of each item is kept on hand, and orders are placed to bring the stock back up to that level.

A Periodic Automatic Replenishment (PAR) level system involves establishing a minimum and maximum quantity for each supply. When the quantity on hand drops to the minimum level, an order is placed to replenish it back to the maximum (PAR) level, ensuring a consistent supply without overstocking.

When transporting sterile items in a cart, which practice is most appropriate?

Answer: Using a covered or enclosed cart and ensuring it is cleaned regularly.

Sterile items must be protected from contamination during transport. Using a covered or enclosed cart shields them from dust, moisture, and physical contact. The cart itself must be part of a regular cleaning schedule to prevent it from becoming a source of contamination.

What is the most critical step to perform before dispensing a sterile package to the end user?

Answer: Inspecting the package for integrity, including checking for holes, tears, moisture, and intact seals.

Before a sterile item is given to a user, the package integrity must be thoroughly inspected. This includes looking for any holes, tears, broken seals, signs of moisture, or other damage that could have compromised the sterile barrier. This final check is a crucial step for ensuring patient safety.
