CIC Cleaning, Disinfection, & Sterilization 3

Question 1

Which low-temperature sterilization method is most appropriate for heat-sensitive, moisture-tolerant flexible endoscopes?

Accepted Answer

Peracetic acid immersion system

Answer

Peracetic acid liquid sterilization systems (e.g., STERIS System 1) are designed for moisture-compatible heat-sensitive items like flexible endoscopes.

Question 2

What does a Class 1 chemical indicator (process indicator) confirm?

Accepted Answer

That the item was exposed to a sterilization process

Answer

Class 1 indicators (e.g., autoclave tape) change color to show that the package was exposed to a sterilization process, not that sterility was achieved.

Question 3

Which disinfectant level is required for non-critical patient care items that contact only intact skin?

Accepted Answer

Low-level disinfection

Answer

Non-critical items that contact intact skin require only low-level disinfection using an EPA-registered hospital disinfectant.

Question 4

The recommended water temperature for manual cleaning of surgical instruments is:

Accepted Answer

30–45°C (86–113°F)

Answer

Warm water between 30–45°C is recommended for manual cleaning because water that is too hot can coagulate proteins, making them harder to remove.

Question 5

Which sterilization method poses the greatest occupational health concern due to its carcinogenic and mutagenic properties?

Accepted Answer

Ethylene oxide (EtO)

Answer

Ethylene oxide is a known human carcinogen and mutagen, requiring strict exposure controls, aeration periods, and OSHA compliance.
