| Question | Answer |
|---|---|
| the OR design that clusters operating rooms by surgical specialty to increase team efficiency with familiar equipment is called | specialty grouping |
| a key disadvantage of the hotel OR design compared to the racetrack design is | longer average travel distance |
| the traffic zone that requires OR attire but does NOT yet require a mask is the _ zone | semi-restricted |
| a visitor in street clothes being escorted through preoperative holding is in the _ zone | unrestricted |
| the case cart system is best described as | getting the instruments in + out of the OR |
| during turnover time, the case cart for the next procedure is delivered by _ | SPD |
| the piece of OR furniture that is usually closest to the operative site is the | mayo stand |
| an area such as the sub sterile room is considered | restricted |
| a fixed white board in the OR is used to record | surgical counts |
| the department must provide a _ detailing information about specific chemicals a CST may encounter | SDS- safety data sheet |
| locker rooms and administrative offices are examples of _ areas in the OR suite | unrestricted |
| surgery departments are specifically designed to control _, _, and _ traffic | personnel, supply, and patient |
| a double corridor design routes clean supply traffic and soiled case cart returns through _ hallways | separate |
| the circulating RN is considered part of the _ surgical team | non-sterile |
| the term used for cleaning an OR and preparing it for the next procedure is | turnover time |
| the three legs of the fire triangle are _, _, and _ | ignition source, oxidizer, + fuel |
| the geometric shape that visually represents the components necessary to support a fire is a | triangle |
| according to the fire triangle, _ any one leg prevents a fire | removing |
| alcohol based prep pooling under drapes before ESU activation represents a failure to control the _ leg of the fire triangle | fuel |
| head/face/neck/upper-chest surgery is the single highest risk zone for surgical fire because | there is an open oxygen |
| the extinguisher most effective on an electrical or laser fire is Class _ | C |
| in the RACE fire response, confine involves _ | close doors + shut off gases/oxygen to help contain the fire |
| static electricity spark risk in the OR is reduced by maintaining relative humidity within the _ range | 20-60% |
| electricity generated by friction between two surfaces is called _ electricity | static |
| there are _ classes of fire extinguishers | five |
| the type of PPE that protects the CST from ionizing radiation is a _ and _ | lead apron + thyroid shield |
| the three core ALARA measures are _, _, and _ | time, distance, + shielding |
| laser eye protection must be selected based on | the specific wavelength of laser |
| when a laser is not actively being fired by the operator, it should be kept in _ mode | standby |
| a class 4 laser poses a hazard from _ light, not only direct beam exposure | reflected |
| the federal agency that enforces workplace safety standards, including the Bloodborne Pathogens Standard is | OSHA |
| the CDC's 1996 standard precautions broadened the 1985 Universal Precautions to include | blood + most other body fluids |
| the one body substance that is the exception and is NOT classified as infectious under standard precautions is | sweat |
| during PPE doffing, the first item that should be removed because it is typically the most contaminated is | gloves |
| alcohol based hand rub must be allowed to fully dry rather than wiped off early because | the alcohol must remain on the hands long enough to kill microorganisms effectively |
| a patient with multiple prior surgeries and a child with spina bifida share an elevated risk for | latex sensitivity |
| hives, wheezing, and hypotension occurring within minutes of glove contact are characteristic of a _ reaction | type 1 |
| a rash that is red, raw, and cracked 24-48 hours after latex contact, without immediate systemic symptoms, is most consistent with | type IV |
| before opening supplies for any case, a CST should confirm latex allergy status by | checking the patients chart and bracelet |
| surgical plume produced by lasers or electrocautery has been shown to contain | infectious DNA + water vapor |
| a smoke evacuator should combine _ and _ filters to address both [articulate and odor hazards | HEPA + charcoal |
| a smoke evacuator wand should be held close to the tissue during lasing and electrocautery because | it reduces plume + exposure to harmful particles |
| the two instruments that are the primary sources of OR sharps injuries are _ and _ | scalpels + blades |
| the neutral zone technique for passing sharps is designed to | reduce the risk of sharps injuries to the surgical team so they don't have to be passed hand to hand |
| immediately after a sharps injury, the correct sequence is | alert, hand off instrument, take gloves off, access the injury |
| blood soaked sponges and drapes should be disposed of in | red biohazard bags |
| the majority of sharps injuries occur in the | OR |
| the equipment that reduces manual handling and aerosol exposure by automatically collecting and disposing of surgical fluid waste is the | neptune |
| the portion of the ESU circuit that delivers current back from exposed tissue to the ESU unit is the | grounding pad |
| OR doors should be kept closed to preserve _ air pressure | positive |
| the OR ventilation system should be _ and _ | positive + one direction |
| waste anesthetic gas (WAG) exposure is minimized primarily through | the scavenging system + OR ventilation |
| PMMA (bone cement) is typically mixed | on back table by the CST |
| in Bone Cement Implantation Syndrome (BCIS) a sudden drop in blood pressure occurs primarily because | pulmonary embolism |
| PACU stands for | post anesthesia care unit |
| surgical lights _ | move horizontally + vertically |
| the articulating arm of the surgical boom is mounted to the _ outlet | wall or ceiling |
| the outlet connected to a backup power source is the _ outlet | red |
| proper body mechanics is referred to as | ergonomics |
| name one member of the sterile surgical team | surgeon |
| name one member of the nonsterile surgical team | circulator (RN) |
| what is the recommended weight limit on instrument trays | 25 lbs |
| what should be attached to the bed when performing surgery on a bariatric patient | side extenders |
| what color are biohazard bags used for contaminated waste | red |
| what does OSHA stand for | occupational safety + health administration |
| what does CSPD stand for | central sterile processing department |

| what is the maximum number of air exchanges required per hour in the OR | 15 |
| name the three elements of the fire triangle | ignition source, oxidizer, and fuel |
