| Term | Definition |
|---|---|
| The _____________ is a piece of equipment that is used for sterilizing by means of hot formaldehyde vapors under pressure. | chemical vapor sterilizer |
| _____________ is the length of time that a germicidal solution is effective after it has been prepared for use. | use-life |
| Another term for spore testing is _____________. | biologic monitoring |
| _____________ means that it is assumed the contents of a package will remain sterile indefinitely unless the packaging is compromised. | event related packaging |
| A(n) _____________ is an indicator that reacts to time, temperature, and the presence of steam. | mutiparameter indicator |
| The _____________ is a device that loosens and removes debris with the use of sound waves traveling through a liquid. | ultrasonic cleaner |
| An example of dry heat sterilization is ____________. | Static air |
| True or False Multiparameter indicators ensure that an item is sterile. | False |
| The _____________ verifies sterilization by confirming that all spore-forming microorganisms have been destroyed. | biologic monitoring |
| The ultrasonic cleaner works _____________. | By sound waves |
| True or False The instrument classifications used to determine the method of sterilization and disinfection are indicators and integrators. | False |
| Which method of precleaning instruments is LEAST desirable? | Hand scrubbing |
| A(n) _____________ is a resistant, dormant structure that is formed inside of some bacteria and can withstand adverse conditions. | Endospore |
| Kitchen dishwashers cannot be used to preclean instruments because they are _____________. | not FDA approved |
| The _____________ of the sterilization center is where contaminated items are brought for precleaning. | Contaminated area |
| _____________ are instruments that come into contact with intact skin only. | non-critical instrument |
| _____________ are vials or strips, also known as spore tests, that contain harmless bacterial spores and are used to determine whether a sterilizer is working. | biologic indicators |
| How do you prepare a high-speed handpiece for sterilization? | Flush water through it. |
| _____is a reason that pins, staples, and paper clips are not used on instrument packaging? | They will cause holes in the packaging. |
| What is a major advantage of chemical vapor sterilization? | Instruments will not rust. |
| An instrument used to penetrate soft tissue or bone is identified as a(n) _____________. | Critical Instrument |
| To maintain proper opening, hinged instruments may be treated with _____________. | Lubricant |
| If instruments cannot be processed immediately, what should be done with them? | they should be placed in a holding solution |
| Instruments that come in contact with oral tissues but do not penetrate soft tissue or bone are identified as _____________. | semicritical instrument |
| Which is a form of sterilization monitoring? | Physical, chemical, biologic |
| What type of heat sterilization is appropriate for high-speed handpieces? | Steam |
| Instruments should be packaged for sterilization to _____________. | maintain sterility |
| What is the best way to determine whether sterilization has occurred? | Use biologic monitoring. |
| _____________ is OSHA’s newer term for material data sheets. | SDS |
| The _____________ is a piece of equipment that is used for sterilizing by means of moist heat under pressure | Autoclave |
| What causes sterilization failures? | Overloading of the sterilizer inadequate instrument precleaning Improper contact of sterilizing agent using excessive thick wrapping |
| What is a primary disadvantage of “flash” sterilization? | Inability to wrap items |
| How do you rinse instruments that have been processed in a liquid chemical sterilant? | With sterile water |
| A piece of equipment used for sterilization by means of heated air is the _____________. | dry heat sterilizer |
| Tapes, strips, and tabs with heat-sensitive chemicals that change color when exposed to a certain temperature are examples of a(n) _____________. | single-parameter |
| The basic rule of the workflow pattern in an instrument-processing area is _____________. | Square |
| Where is a process indicator placed? | outside the package |
| What are commonly used forms of heat sterilization? | Steam, chemical vapor, dry heat |
| In the _____________ of the sterilization center, sterilized instruments, fresh disposable supplies, and prepared trays are stored. | Clean area |
| What type of personal protective equipment is necessary when one is processing instruments? | Utility gloves Mask Protective clothing Protective eyewear |
| What are the three instrument classifications used to determine the method of sterilization? | Critical, semi-critical, and non-critical instruments. |
| What is the basic rule of the workflow pattern in an instrument-processing area? | The workflow should move from dirty to clean to sterile, without doubling back. |
| Name the two methods of precleaning instruments. | Hand scrubbing (manual) and ultrasonic cleaning (mechanical). |
| How does an ultrasonic cleaner work? | It uses sound waves to create bubbles that dislodge debris from instruments. |
| .What are the two types of dry heat sterilization? | Static air and forced air sterilization. |
| What is the primary disadvantage of liquid chemical sterilization? . | It requires long contact times and cannot be biologically monitored |
| What is a process indicator, and where is it placed? | A process indicator shows exposure to sterilization conditions and is placed outside the package. |
| What is a process integrator, and where is it placed? | A process integrator monitors time, temperature, and pressure and is placed inside the package. |
| .Do process indicators and integrators ensure that an item is sterile? | No, they only confirm exposure to sterilization conditions, not sterility. |
| .What does event-related packaging mean? | Sterility is maintained unless the package is damaged or opened |
