Term | Definition |
---|---|
The label on a chemical agent contains all of the following except | The manufacturer suggested retail price. |
For sterilization to occur using an immersion disinfectant, items must be immersed for a minimum of _____ hours. | 6 |
To avoid contamination in a dental treatment area, the best approach is to | assume all surfaces have been contaminated. |
The purpose of precleaning a surface is to reduce the number of microbes and remove blood, saliva, and other body fluids called | bioburden. |
The agency that regulates and registers disinfectants and chemical sterilants according to chemical classification is | the EPA. |
The use of barriers on surfaces and equipment can prevent contamination of contact areas. The correct protocol for their use would include | removing and discarding with gloved hands, and replacing using clean gloves between patients. using a barrier resistant to fluids. |
The high-level disinfectant that does not require activation or mixing and has little odor is | ortho-phthalaldehyde (OPA). |
Carpet in dental treatment areas | harbors both bacteria and fungi. |
A product capable of killing a virus should be labeled | virucidal. |
Precleaning can be accomplished using | regular soap and water. |
Which of the following can be used as a surface disinfectant in the dentistry? | Synthetic phenols |
Acceptable barriers include | clear plastic wrap. plastic bags. tubing and plastic-backed paper. |
Disinfectants used in dentistry must be registered with the Environmental Protection Agency (EPA) as hospital disinfectants with the ability to kill | Mycobacterium tuberculosis. |
“Green” infection control protocols can be implemented in all of the following except | traditional film-based radiography. |
A product capable of killing spores is | a sporicidal. |
The protocol to follow to minimize contamination of touch and transfer surfaces from splash, spatter, and surface droplets is to | apply an acceptable barrier following precleaning and disinfection. |
The agency responsible for the Blood-Borne Pathogens Standards that requires contaminated surfaces to be disinfected between patients, even if no evidence of contamination is visible is | OSHA. |
By current infection control guidelines of the Organization for Safety and Asepsis Procedures (OSAP), chairside computers are considered to be _____ surfaces. | touch |
All of the following surfaces should be protected from contamination with barriers except | counter tops in the reception area. |
One reason for taking precautions when using complex phenols for disinfection is that they | can degrade some plastics or etch the surface of glass. |
Under the CDC Guidelines for Infection Control in Dental Healthcare Settings—2003, housekeeping surfaces include | floors. walls. sinks. |
Precautions when using glutaraldehyde include | avoid inhaling the fumes. always rinse instruments thoroughly prior to any intraoral use. wear PPE to protect the eyes, skin, and lungs. |
Following OSAP protocol, surface barriers | should be removed and discarded between patients while hands are still gloved. |
The appropriate disinfection protocol to follow when a surface has been covered with a barrier is | clean and disinfect the surface at the beginning and end of each workday. |
Instability, daily preparation, strong odor, and corrosion are some of the disadvantages of | sodium hypochlorite. |
Housekeeping surfaces | need to be cleaned with only a detergent or low-level disinfectant. |
The chemical disinfectant classified as an intermediate-level agent that is no longer recommended for use in dentistry is | sodium hypochlorite. |
According to the EPA, synthetic phenol compounds are categorized as intermediate-level hospital disinfectants. Phenols can be used on | metal. glass. rubber or plastic. |
Some microorganisms may survive on outside the host on environmental surfaces. The organism of concern to dentistry that can survive for weeks outside the host is | tuberculosis. |
The following are considered single-use items except | metal impression trays. |
