This low-level disinfectant is incompatible with soap. Which one is it?

When using glutaraldehyde, technicians should always wear latex gloves for protection.

When using high-level disinfectants, they may be deactivated by?

In an automated washer, the key source of disinfection is:

The use of test strips to test the minimum effective concentration in high-level disinfection solutions is required:

The use of heat to kill all microorganisms, except spores, is called:

These chemicals are used on animate (living tissue) to slow the growth of microorganisms:

Items that are introduced directly into the bloodstream or other normally sterile areas of the body are classified as:

The process by which all forms of microorganisms are completely destroyed is:

Iodophors are a member of this chemical family:

Phenolics are classified as:

Which of the following are classified as high-level disinfectants?

Thermal disinfection is accomplished using:

How long must alcohol remain in wet contact with an item to achieve a reasonable level of disinfection?

Which of the following would be the best choice for high-level disinfection of instruments?

Quaternary ammonium compounds are low-level disinfectants incompatible with soap.
Glutaraldehyde does not require latex gloves for protection; this statement is false.
High-level disinfectants are particularly susceptible to deactivation by organic matter.

In automated washers, water temperature plays a crucial role in disinfection effectiveness.
Test strips are essential for verifying the minimum effective concentration of high-level disinfection solutions each time the solution is utilized.

Thermal disinfection uses heat to eliminate all microorganisms except spores.
Antiseptics are chemicals applied to living tissue to inhibit microorganism growth.
Critical items refer to those introduced into sterile areas or the bloodstream, necessitating stringent sterilization protocols.
Sterilization is the complete eradication of all microorganisms.

Iodophors belong to the halogen family of disinfectants.
Phenolics are categorized as intermediate to low-level disinfectants.
High-level disinfectants include glutaraldehyde and ortho-phthalaldehydes, which are preferred for instrument disinfection.

Thermal disinfection is solely achieved through the application of heat.
Alcohol requires prolonged wet contact of 5-10 minutes to attain effective disinfection levels.
Ortho-phthalaldehydes are recommended as the optimal choice for high-level disinfection of instruments.
