Free MDRAO Sterile Storage, Handling, and Distribution Questions and Answers

Question 1

What are the ideal environmental conditions for a sterile storage area?

Accepted Answer

Positive air pressure, with controlled temperature and humidity.

Answer

Sterile storage areas should have positive air pressure relative to adjacent areas to prevent airborne contaminants from entering. Temperature and humidity must also be controlled (e.g., temp below 24°C, humidity 30-60%) to protect the integrity of sterile packaging and prevent microbial growth.

Question 2

The shelf life of a sterilized package is considered to be:

Accepted Answer

Event-related, not time-related.

Answer

Modern standards recognize that sterility is 'event-related,' meaning an item remains sterile until an event compromises the package integrity. Such events include punctures, moisture contamination, or excessive handling, rather than the simple passage of a predetermined amount of time.

Question 3

According to CSA standards, how far from the floor should the bottom shelf in a sterile storage area be?

Accepted Answer

At least 25 cm (10 inches).

Answer

Storing sterile items at least 25 cm (10 inches) off the floor protects them from contamination during floor cleaning and from ambient floor-level contaminants. This clearance also allows for proper air circulation and effective cleaning underneath the shelving units.

Question 4

When handling a sterile package, what is the most important principle to follow?

Accepted Answer

Ensure your hands are clean and handle it as little as possible.

Answer

Every time a sterile package is handled, there is a risk of compromising its integrity. It is crucial to have clean, dry hands and to handle the package minimally, supporting it from the bottom and avoiding crushing, bending, or dropping it.

Question 5

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

Accepted Answer

The oldest sterile supplies are used first.

Answer

FIFO is a stock rotation method where the items that were sterilized and placed in storage first are the first ones to be removed for use. This system helps minimize the chance of packages expiring (if using time-related dating) and reduces the potential for damage from prolonged storage.
