CIS CIS - Certified Instrument Specialist Storage and Distribution of Surgical Instruments Questions and Answers

Question 1

What is the recommended maximum shelf life for sterile wrapped instrument sets stored in a closed cabinet under controlled conditions?

Accepted Answer

Event-related, not time-related

Answer

Modern sterile processing guidelines follow an event-related sterility concept, meaning sterility is maintained until an event compromises the packaging rather than a fixed time limit.

Question 2

Which environmental condition in the sterile storage area is most critical to preventing premature compromise of sterile packages?

Accepted Answer

Relative humidity

Answer

High humidity can weaken packaging materials, allow moisture penetration, and compromise the sterile barrier, making humidity control critical in sterile storage areas.

Question 3

What is the AAMI-recommended temperature range for a sterile storage area?

Accepted Answer

65–75°F (18–24°C)

Answer

AAMI ST79 recommends sterile storage areas be maintained between 65–75°F (18–24°C) to preserve packaging integrity and instrument condition.

Question 4

Why should sterile packages never be stored on the floor of a sterile storage room?

Accepted Answer

Floors are considered contaminated surfaces and packages could be damaged

Answer

Floors are considered contaminated areas and are subject to moisture, foot traffic, and cleaning chemicals that can compromise sterile packaging.

Question 5

What minimum distance from the floor should sterile items be stored according to standard sterile processing guidelines?

Accepted Answer

8–10 inches

Answer

AAMI ST79 recommends storing sterile items at least 8–10 inches off the floor to protect them from floor-level contamination and moisture.
