Question 3

Match between columns
                        Premises: Ignition source caused by friction between two surfaces and electron transfer; resulting in sparks or palpable shocks
Category of "sharp" that has a beveled point and hollow cannula and either should not be recapped or should involve using the one-handed scoop method if recapping is necessary
Real-time intraoperative radiography that emits large amounts of ionizing radiation and requires use of a C-arm image intensifier
Separate department with direct or indirect connections to OR suite where instrument decontamination, assembly, and sterilization takes place and may include hospital materials storage
Surgical energy that uses intense focused light beams and is an ignition source for surgical fires if proper precautions not taken
Area of an operating room suite where patients have IV lines started, sign consents, interview with surgeons, anesthesia providers, and nurses prior to transfer to the OR for procedures
Connection points for negative pressure lines that allow for removal of irrigation and body fluids from the surgical site or by the anesthesia provider for management of patient secretions
Positive pressure gradient that prevents airborne contaminants in the corridors from entering the OR when doors are opened
Area of an operating room suite adjacent to an OR, which may contain a scrub sink or immediate-use steam sterilizer
Equipment used by CRNA or MD for induction, maintenance, monitoring, and reversal of a patient undergoing surgery

Question 4

Infectious, blood-saturated and dripping, regulated medical waste should be contained and discarded in red bags with a biohazard symbol.

Accepted Answer

Infectious, blood-saturated and dripping, regulated medical waste should be contained and discarded in red bags with a biohazard symbol according to proper medical waste management guidelines.

Question 5

All of the following are articulating breakpoints or removable sections of an operating table EXCEPT:

Accepted Answer

The articulating breakpoints or removable sections of an operating table typically include the head, knee, and waist sections. The side is not a commonly recognized articulating breakpoint or removable section.

Question 6

Locker rooms, administrative offices, and the departmental main desk are examples of semirestricted areas in the OR suite.

Accepted Answer

Locker rooms, administrative offices, and the departmental main desk are examples of unrestricted areas in the OR suite, where there is a mix of hospital staff and visitors, and surgical attire is not required.

Question 7

Which of the following is the mnemonic used to remember the steps to take in the event of a surgical fire?

Accepted Answer

RACE (Rescue, Alarm, Contain, Extinguish) is the mnemonic used to remember the steps to take in the event of a surgical fire. PASS is used for operating a fire extinguisher, and PMMA and RAST are not related to surgical fires.

Question 8

Polymethyl methacrylate is a gas used to sterilize heat-sensitive surgical instruments, but must be aerated from items before use on the patient.

Accepted Answer

Polymethyl methacrylate (PMMA) is not a gas; it is a synthetic polymer of methyl methacrylate, used in a wide range of applications, including as a glass substitute in items such as aquariums, motorcycle helmet visors, and as a bone cement in orthopedic surgery. The gas used for sterilizing heat-sensitive surgical instruments is ethylene oxide, not PMMA.

Question 9

Which of the following is the mnemonic used to remember the steps for operating a fire extinguisher?

Accepted Answer

PASS is an acronym for Pull the pin, Aim at the base of the fire, Squeeze the lever, and Sweep from side to side.

Question 10

Which of the following organizations sets standards for electrical safety, sterilization, and use of medical devices?

Accepted Answer

AAMI (Association for the Advancement of Medical Instrumentation) sets standards for electrical safety, sterilization, and use of medical devices. ANSI (American National Standards Institute) sets general safety standards, CPS (Consumer Product Safety Commission) sets safety standards for consumer products, and OSHA (Occupational Safety and Health Administration) sets safety standards for workplaces.

Question 11

The physical design of an OR suite is designed to control personnel, patient, and supply traffic and may be of a race track, hotel, or specialty grouping type.

Accepted Answer

The physical design of an OR suite is indeed designed to control personnel, patient, and supply traffic and can take the form of a race track, hotel, or specialty grouping type.

Question 12

What is the abbreviation for the sets of references that provide information about all potentially hazardous chemicals used in the perioperative setting and must be accessible to health care workers?

Accepted Answer

MSDS stands for Material Safety Data Sheets, which are documents that provide information on the potential hazards of chemicals, as well as instructions for their safe use, handling, storage, and disposal. MSDSs are required by law in the United States under the OSHA Hazard Communication Standard and must be readily accessible to employees who may be exposed to hazardous chemicals in the workplace. This includes health care workers in the perioperative setting. AAMI is the Association for the Advancement of Medical Instrumentation, NIOSH is the National Institute for Occupational Safety and Health, and OSHA is the Occupational Safety and Health Administration. While these organizations all have roles in promoting safety in the workplace, none specifically require or provide MSDSs.

Question 13

Soiled sponges from the operative field are discarded into low-to-the-floor, rolling, lined kick buckets.

Accepted Answer

This is a common practice in surgical settings to ensure easy access and disposal of soiled sponges without risking contamination of other areas in the operating room.

Question 14

Which of the following is commonly used as a tissue fixative and preservative for surgical specimens sent to pathology?

Accepted Answer

Formalin is the most commonly used fixative and preservative for surgical specimens sent to pathology. It helps to preserve the tissue structure and cellular architecture, preventing decay and autolysis. Ethylene oxide and glutaraldehyde are also used as fixatives, but they are less commonly used in surgical pathology. Polymethyl methacrylate is a plastic resin used for embedding tissues for histology, but it is not a fixative or preservative.

Question 15

Which of the following should be used by surgical team members to prevent potential injury from tasks involving heavy lifting, moving of equipment or patients, and long periods of standing or sitting?

Accepted Answer

Proper body mechanics should be used to prevent potential injury from tasks involving heavy lifting, moving of equipment or patients, and long periods of standing or sitting. Permissible exposure limits and post-exposure prophylaxis are irrelevant to this situation, while personal protective equipment may be necessary for other types of safety hazards in the surgical setting.

Question 16
