chapter 20 and 21
| Question | Answer |
|---|---|
| The high-level disinfectant that does not require activation or mixing and has little odor is | ortho-phthalaldehyde (OPA |
| 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. All of the above |
| Precleaning can be accomplished using | regular soap and water. |
| 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 |
| Recommendations for mixing solutions of detergents or disinfectants include | making a fresh cleaning solution each day and discarding any unused solution at the end of the treatment day. |
| If the surface below the barrier is inadvertently touched when removing a contaminated barrier, the protocol to follow indicates | the surface needs to be cleaned and disinfected. |
| One of the benefits of using a complex phenol solution for disinfection is that they | are compatible with metal, glass, rubber, and 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. |
| Housekeeping surfaces | need to be cleaned with only a detergent or low-level disinfectant. |
| Disinfectants used in dentistry must be registered with the Environmental Protection Agency (EPA) as hospital disinfectants with the ability to kill | Mycobacterium tuberculosis. |
| The label on a chemical agent contains all of the following except | The manufacturer suggested retail price. |
| The purpose of precleaning a surface is to reduce the number of microbes and remove blood, saliva, and other body fluids called | bioburden. |
| 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. Both A and B |
| The chemical disinfectant classified as an intermediate-level agent that is no longer recommended for use in dentistry is | sodium hypochlorite. |
| Chemicals that destroy or inactivate most species of pathogenic microorganisms on inanimate surfaces are called | disinfectants. |
| One reason for taking precautions when using complex phenols for disinfection is that they | can degrade some plastics or etch the surface of glass. |
| To avoid contamination in a dental treatment area, the best approach is to | assume all surfaces have been contaminated. |
| 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. |
| Acceptable barriers include | clear plastic wrap. plastic bags. tubing and plastic-backed paper. All of the above |
| 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. |
| Carpet in dental treatment areas | harbors both bacteria and fungi. |
| Green” infection control protocols can be implemented in all of the following except | traditional film-based radiography. |
| The following are considered single-use items except | metal impression trays. |
| Instability, daily preparation, strong odor, and corrosion are some of the disadvantages of | sodium hypochlorite. |
| A product capable of killing spores is | a sporicidal. |
| For sterilization to occur using an immersion disinfectant, items must be immersed for a minimum of _____ hours. | 6 |
| Following OSAP protocol, surface barriers | should be removed and discarded between patients while hands are still gloved. |
| Which of the following can be used as a surface disinfectant in the dentistry? | Synthetic phenols |
| The minimum frequency recommended by the CDC, ADA, and OSAP for biologic monitoring of all sterilizing equipment is | weekly. |
| All of the following are chemicals used to create vapor for sterilizing with chemical vapor sterilization except | sodium hypochlorite. |
| One of the disadvantages of flash sterilization is the | inability to wrap items. |
| What is the major advantage of forced air sterilizers over the other types of sterilizers? | Short sterilization cycle time |
| Sterilization errors include | improper packaging. improper timing. improper loading. All of the above |
| Recommended methods for sterilizing dental handpieces include | steam sterilization. chemical vapor sterilization. Both B and C |
| Biologic monitoring is also known as ________ testing. | spore |
| The ultrasonic cleaner should be cleaned and disinfected | at least once a day. |
| When transporting and processing contaminated patient care items, precautions need to be taken to avoid personal exposure to microorganisms through | percutaneous injury. contact with mucous membranes of the eye, nose, or mouth. breathing aerosol from disinfectant and other chemicals. All of the above |
| Sterilization destroys | all microbial forms, including bacterial spores. |
| A tear in an instrument package requires the dental assistant to | use a new instrument package |
| The temperature during handpiece sterilization should never exceed ____° F. | 275 |
| Which of the following patient care items is classified as a semicritical instrument? | Amalgam carriers |
| An ultrasonic cleaning solution | should be specially formulated for use in only the ultrasonic cleaner. |
| The ideal instrument-processing area should be | dedicated only to instrument processing. |
| All of the following will cause a sterilization failure except | using correct packaging material. |
| The autoclave cycle that allows the steam under pressure to be released from within the chamber is the _______________ cycle. | depressurizing |
| Drying instruments to prevent rusting is essential when processing in | chemical vapor. |
| Personal protective equipment (PPE) that must always be used when processing instruments includes | utility gloves, a mask, eyewear, and protective clothing. |
| The purpose of an instrument holding solution is to | prevent the drying of blood and debris on instruments. |
| The best way to determine whether sterilization has occurred is to use | biologic monitors. |
| The least desirable method of precleaning dental instruments is | hand scrubbing. |
| The ultrasonic cleaner should be tested by | submersing a piece of aluminum foil for 20 seconds while the machine is functioning. |
| Ultrasonic cleaners are used to | loosen and remove debris from instruments. reduce risk of hand injury from cuts and punctures that can occur with hand scrubbing. do both A and C. |
| The order of the cycles of a steam sterilizer is | heat-up; sterilizing; depressurization; drying. |
| Some ultrasonic cleaning solutions have | enzymatic activity. antimicrobial activity. Both B and C |
| A method for sterilizing unwrapped patient care items for immediate use is | flash sterilization. |
| Why is it important for packages to dry inside the steam sterilizer before storage? | Wicking of bacteria can occur through wet packaging material. |
| Which of the following is true regarding the use of spore testing to monitor sterilization? | A positive culture indicates a sterilization failure has occurred. |
| A monitoring service will immediately communicate a failure of sterilization through | a telephone call to the dental office, reporting a positive result. |
