Answer 3

30% and 60%

Question 4

(F)AN

Answer 4

Function. Each item in the park must function as it was designed. This means that scissors must be sharp, clamps must hold securely, and multi-part items must be complete and functional when assembled. Technicians reach that goal by understanding how instruments operate and my relying on specific test methods to ensure the they work properly

Question 5

F(A)N

Answer 5

Accurate. Instrument must be correct and quantities must be exact. Technicians meet this goal by learning to identify specific instruments, working from an up-to-date pack content list and verifying that all specifications for the pack – including quantities and configuration —- are correct

Question 6

FA(N)

Answer 6

Neat. Pack contents must be organized, and instrument must be easy to locate, Disorganized packs may waste time or delay treatment and care.

Question 7

Smaller groups of instruments used for smaller procedures in the area outside of the OR, such as suturing, wound irrigation or cutdowns are called

Answer 7

Procedure trays also known as floor trays

Question 8

Clearly-written and illustrated procedures for preparation of items to be packaged

Answer 8

Count Sheets

Question 9

What ways does moisture affect different sterilization processes?

Answer 9

1. ) Steam cycles - Moisture will change the wet/dry steam ratio
2. ) Ethylene oxide (EtO) cycles - Moisture will form ethylene glycol, which is harmful to staff and patients
3. ) Hydrogen peroxide and ozone cycles - Moisture will cause the cycle to abort

Question 10

Reversing the magnetic field away from instruments

Answer 10

Demagnetizers

Question 11

The FDA classifies sterilization packaging as a ______

Answer 11

Class II medical device (a device that presents a potential risk)

Question 12

The two types or reusable packaging material

Answer 12

1. ) Woven Fabric

2. ) Rigid Containers

Question 13

Linen packs are limited to ________

Answer 13

12” (Height) x 12” (Width) x 20” (length), and they are not to weigh more than 12 pounds per cubic foot

Question 14

Answer 14

engineered fabrics aka disposable non-woven materials in the 1940s (Coffee filters, teabags, vacuum cleaner bags)

Question 15

Most commonly-used packaging materials for small instruments and lightweight items

Answer 15

Paper/plastic and spunbond polyolefin-plastic combinations aka Peel packs or peel pouches

Question 16

Paper/plastic combination are typically used with _____

Answer 16

Steam and EtO sterilization processes

Question 17

Spunbond polyolefin-plastic combinations aka Tyvek pouches are used for _______

Answer 17

Hydrogen peroxide and ozone sterilization

Question 18

Applied to packages after sterilization to protect the package from dust, moisture and other contaminates.

Answer 18

Protective plastic overwrap aka (dust covers or sterility maintenance covers)

Question 19

Who recognizes sterility as “event-related”?

Answer 19

The joint Commission (TJC) and the Association of periOperative Registered Nurse (AORN)

Question 20

Two techniques for wrapping packages

Answer 20

1. ) Square Fold - This is also called the in-line or parallel fold; it is most frequently used for larger packs and instrument trays
2. ) Envelope Fold - This is more commonly used for individual items, small packs and most instruments sets..

Question 21

Two methods of using flat wrapper packs

Answer 21

1. ) Sequential - The package is wrapped twice and is “a package within a package.” The term “sequential” indicates that the contents have been wrapped in sequence (one after the other). This method is used for muslin, Kraft-type paper and single layers of SMS wraps.
2. ) Simultaneous - The package is only wrapped once, but it requires a special double-layered synthetic non-woven material bound on two or four sides

Question 22

Advantages/Disadvantages of sequential wrap

Answer 22

Pros: Affords a “2nd chance” for sterile presentation

Cons: Requires more time for wrapping and unwrapping

Question 23

Advantages/Disadvantages of simultaneous wrap

Answer 23

Pros: Reduced labor costs and increased output in the CS and OR.

Cons: Absence of the second layer removes the “second chance” aspect during aseptic opening/presentation.
