| which item is a typical cart washer application | a compatible case cart |
| what should be done with a flexible scope when its IFU requires leak testing | leak test before immersion/manual cleaning as directed |
| how should hinged instruments usually be prepared when the IFU directs it | open so sterilant can contact required surfaces |
| which is the required function of sterilization packaging | allow sterilant penetration and maintain a microbial barrier afterward |

| what role does pressure serve in steam sterilization | it allows saturated steam to reach the required higher temperature |
| which statement about IUSS is correct | full cleaning and inspection are still required |
| a heat sensitive device is being considered for hydrogen peroxide sterilization. what mist be checked | device, packaging, lumen, and system compatibility |
| which statement about liquid chemical sterilization is accurate | rinsing and handling limit sterility assurance and storage |
| what does a Bowie-Dick test evaluate | air removal and steam penetration in an applicable prevacuum sterilizer |
| the processed BI and its unprocessed positive control are both negative. how should you interpret this | the test is invalid because the control did not show expected activity |
| which chemical indicator type integrates all critical variables across its specific range | type 5 |
| an unopened item is past its manufacturer expiration date. what should happen | remove it from use according to policy |
| which steam load requires biological indicator monitoring for the implantable item | every load containing implants |
| asepsis concerns preventing contamination. sterile technique is the set of practices that protects the sterile field and its contents | asepsis and sterile technique |
| recognize, report, and correct a break in technique even when no one else sees it | surgical conscience |
| the number of viable microorganisms present on an item or surface. cleaning reduces the burden | surgical conscience |
| the number of viable microorganisms present on an item or surface, cleaning reduces this burden | bioburden |
| microorganisms attached to a surface within a protective matrix. complex channels require thorough cleaning | biofilm |
| contamination means organism are where they should not be. infection involves tissue invasion and a host response or injury | contamination and infection |
| colonization does not necessarily produce disease. normal flora may cause infection if carried into a normally sterile site | colonization and normal flora |
| resistant flora persist on the body. transient flora are acquired through contact and can be carried to other surfaces | resistant and transient flora |
| an inanimate object that can carry microorganisms, such as a contaminated control or instrument | fomite |
| moisture can move through permeable material and carry microorganisms across a barrier. a wet package must not be used | strike through and wicking |
| bactericidal means kills bacteria. bacteriostatic means inhibits bacterial growth | bactericidal and bacteriostatic |
| sporicidal activity targets bacterial spores. tuberculocidal activity includes mycobacterium tuberculosis | sporicidal and tuberculocidal |
| HAI is an infection associated with healthcare. a surgical site infection involves the operative incision or associated operative site | healthcare associated infection and SSI |
| Surgically clean does not establish sterility. a critical item needs validated sterilization and protected handling | surgically clean and sterile |
| an eligible intact barrier can maintain sterility until a compromising event; honor labeled expiration dates | event related sterility |
| broad activity including mycobacteria, fungi and viruses; not reliably large numbers spores under HLD conditions | high level disinfection |
| tuberculocidal; not reliably sporicidal | intermediate level |
| many vegetative bacteria and some fungi/viruses; not reliably TB or spores | low level |
| action and limit | cleaning method |
| friction, correct brushes, and channel slushing as directed. Enzymatic products help break down soil; they do not replace sterilization | manual |
| cavitation helps loosen soil on compatible devices. this is not sterilization | ultrasonic |
| automated cleaning, rinsing, and a disinfection phase. correct loading and adapters matter | washer disinfector |
| cleans compatible larger transport items and equipment; not automatically suitable for every instrument | cart washer |
| what you need to protect | step |
| remove gross soil and keep it from drying. flush lumens as directed. protect sharps and delicate devices | during use |
| use closed, leak resistant labeled containment and a designated dirty route | transport |
| use appropriate utility gloves and splash/contaminate protection. disassemble and clean every required surface | decontamination |
| remove soil and detergent residue; use approved methods for internal channels | rinse and dry |
| check cleanliness, function, damage, insulation, and delicate surfaces. Reclean soiled items and remove damaged items. use the set count sheet | inspect and assemble |
| choose a compatibility sterile barrier, protect points, position items correctly, and label for traceability without damaging the barrier | package and label |
| use a validated compatible cycle. review the applicable cycle records and indicators | sterilize and monitor |
| confirm required results., dryness and integrity. protect items through delivery and aseptic opening | release store and distribute |
| checks that matter | package |
| correct size, unstressed seal, no punctures. double pouch only in a validated permitted configuration | peel pouch |
| correct material and folding method, secure approved closure, no tears or wetness. set arrangement must allow processing and drying | wrapped set |
| compatible system and load; correct filters or valves, seals, locks, gaskets and indicator placement. do not mix incompatible components | rigid container |
| what it tells you and what it does not | method |
| reordered cycle performance, such as steam time, temperature, pressure and alarms. review each load against its validated cycle | mechanical or physical |
| response to specified variables. external identifies exposure; internal evaluates conditions at its location. neither proves every instrument sterile | chemical |
| a resistant spore challenge of microbial lethality. steam commonly uses geobacillus stearothermophilus. use the approved BI, challenge device, reader, control and read time | biological |
| type 2 chemical air removal/steam-penetration test for applicable prevacuum sterilizers, perform before the first load each fay of use, after required warm up, in an otherwise empty champers per IFUs. it is not a BI | bowie dick |
| steam is commonly used for compatible heat/moisture-stable items. IUSS requires full cleaning, inspection, validated processing and prompt protected transfer for use; it is not routine storage or an inventory shortcut | steam and IUSS |
| a low temp option for compatible heat-sensitive devices, confirm dry preparation, materials, packaging, lumen limits and system-specific monitoring | hydrogen peroxide |
| check complete contact, concentration, exposure, temp, use-life and rinsing. HLD contact time does not automatically mean sterilization. rinsing and handling limit storage/sterility assurance; do not apply steam BI monitoring to this process | liquid chemical processing |
| EtO requires exposure controls and aeration. Dry heat, ionizing radiation for manufactured supplies, and other specialized systems have distinct validated uses. Keep EtO study brief | EtO and other recognition topics |
| clean, dry, protected storage away from skinks and dirty processing, support packs without crushing or puncturing; limit handling and overcrowding | location and placement |
| class examples: 8-10 in above floor, 2 in from outside wall, 18 in below sprinkler heads. verify current facility and fire requirements | clearances |
| earliest expiration first when dates differ; oldest acceptable stock first when dates match. check integrity and manufacturer expiration | stock rotation |
| case cart: procedure preference care. Par: replenish established quantities. requestion: request supplies. automated: record issue/inventory. specialty or just in time: supply a specialty or scheduled need | distribution |
| retain required load/sterilizer ID, contents, date, operator and monitoring records; link to patient when required. labels and records support recalls | traceability |
| wetness, tears, punctures and broken seals require removal from use. assess dropped items under package-specific policy; do not assume all dropped packs are usable | events |
