Question 1

Which of the following terms relates to the potential impact on personnel from the duties of the job description or the handling and use of equipment and supplies encountered within the perioperative environment?

Accepted Answer

Ergonomics is the study of people's efficiency in their working environment, focusing on how to design jobs, equipment, and workplaces to fit workers' needs and to prevent injuries, which directly relates to the potential impact on personnel from their job duties and the use of equipment and supplies in the perioperative environment.

Question 2

Which type of procedure would require an operating table with a fluid drain pan attachment?

Accepted Answer

A cystoscopy is a procedure that involves inserting a scope into the bladder through the urethra. During this procedure, fluid is often used to help visualize the interior of the bladder, and a drain pan attachment on the operating table would be necessary to collect the fluid. Cardiac catheterization and coronary artery bypass typically do not involve the use of fluids that would require a drain pan, and a craniotomy involves operating on the brain, which would not typically involve the use of fluids that need to be drained.

Question 3

The emergency shut-off valve for the supply of oxygen into an operating room is designated by which color?

Accepted Answer

The color designated for the emergency shut-off valve for oxygen supply is green. This is a standard color coding used in medical gas supply systems to help quickly identify the type of gas.

Question 4

What is the electrical engineering safety device required for all operating room electrical outlets?

Accepted Answer

The safety device required for all operating room electrical outlets is the grounding system. This ensures that any electrical fault or surge is directed to the ground, preventing harm to patients and staff. Flip top covers and red-color designation may be used for additional safety measures, but alone they do not provide sufficient protection against electrical hazards. Current converters are not safety devices, but rather devices used to convert electrical power from one form to another.

Question 5

An erasable board is usually hung in the OR that is within easy viewing range of the surgical team to record:

Accepted Answer

An erasable board is usually placed in the OR to record the usage of surgical sponges, keep track of sharps, and maintain instrument counts. Therefore, the best choice is option D, i.e, all of the above.

Question 6

An operating room where a surgical procedure is in progress would be considered what type of area?

Accepted Answer

An operating room where a surgical procedure is in progress would be considered a restricted area. Restricted areas are areas where the highest level of control over environmental contaminants is required, and where protective clothing and gear is often required to enter.

Question 7

Which characteristic of surgical overhead lights allows the surgeon to differentiate between the colors of arterial and venous blood or subtle color changes in tissues?

Accepted Answer

Lightbulbs that approximate sunlight (such as halogen or LED bulbs) provide a high color rendering index (CRI), which allows for accurate color recognition, making it easier for the surgeon to differentiate between tissue colors and visualize subtle changes in tissue color.

Question 8

What is the term used for the process of cleaning an OR after one procedure and preparing for a subsequent one?

Accepted Answer

Turnover is the term used for the process of cleaning an OR after one procedure and preparing for a subsequent one.

Question 9

Which piece of OR furniture is usually the MOST proximal to the operative site?

Accepted Answer

The Mayo stand is the piece of OR furniture that is usually the most proximal to the operative site. It holds instruments and supplies that the surgeon needs during the procedure and is usually located just beside the patient. The back table is typically behind or to the side of the Mayo stand, the kick bucket is located on the floor near the surgical field to dispose of waste, and the ring stand holds various instruments and equipment but may be located further away from the surgical field.

Question 10

The Wilson frame is used for positioning a patient in which of the following surgical positions?

Accepted Answer

The Wilson frame is specifically designed to support patients in the prone position during surgery, allowing for optimal access to the surgical site while minimizing pressure on the abdomen.

Question 11

Which of the following components of personal protective equipment (PPE) are worn for procedures using fluoroscopy?

Accepted Answer

Lead aprons and thyroid shields are typically worn for procedures using fluoroscopy to protect against radiation exposure. The other choices listed are not necessary for this type of procedure.

Question 12

Which of the following national agencies is an arm of the CDC and functions under the U.S.Department of Health and Human Services to research and establish permissible exposure limits for chemical vapors and gases?

Accepted Answer

The National Institute for Occupational Safety and Health (NIOSH) is an arm of the CDC and operates under the U.S. Department of Health and Human Services. Its mission is to research and establish permissible exposure limits for chemical vapors and gases. AAMI, ANSI, and NFPA are all standards organizations with different areas of focus.

Question 13

Frozen section biopsies are sent to which hospital department for analysis?

Accepted Answer

Frozen section biopsies are typically sent to the pathology department for immediate analysis.

Question 14

Which of the following is NOT a category of hazard for OR personnel or surgical patients?

Accepted Answer

Physiological hazards are not a category of hazard for OR personnel or surgical patients. The three main categories are biological, chemical, and physical hazards.

Question 15

Where are surgical instrument "booms" mounted in an operating room?

Accepted Answer

Surgical instrument booms are typically mounted on the ceiling in an operating room to keep them out of the way and maximize floor space for medical personnel and equipment. Ceiling-mounted booms also provide flexibility in positioning the instruments based on the needs of the surgical team.

Question 16

All doors into a restricted area must remain closed during an operation to:

Accepted Answer

The answer of All doors into a restricted area must...

Question 17

Unless the patient is at risk of hypothermia, the temperature range in the OR should be between:

Accepted Answer

The recommended temperature range in the operating room (OR) for patient comfort and to reduce the risk of hypothermia, unless the patient is at risk of hypothermia and requires a different temperature setting, is between 68°F and 73°F. This range helps maintain normothermia, reducing the risk of surgical site infections and promoting patient comfort.

Question 18

Which type of ventilation system provides a supply of clean air and reduces contaminants and fumes from the OR?

Accepted Answer

Positive pressure unidirectional ventilation systems provide a supply of clean air and reduce contaminants and fumes from the OR by pushing the air out of the room through filters, rather than pulling it in from outside the room (as negative pressure systems do). This helps keep the OR sterile and reduces the risk of airborne infections.

Question 19

The visual representation of the components necessary to support a fire is which of the following geometric shapes?

Accepted Answer

The visual representation of the components necessary to support a fire is often depicted as a triangle, known as the fire triangle. This triangle illustrates the three elements a fire needs to ignite and sustain: heat, fuel, and oxygen.

Question 20

What are the Centers for Disease Control and Prevention (CDC) guidelines for OR air exchanges per hour?

Accepted Answer

The CDC guidelines state that operating rooms should have 20-25 air exchanges per hour with at least 20% fresh outside air. This helps ensure that airborne pathogens are effectively removed from the OR and the air is constantly refreshed. Using recirculated air without adequate fresh air intake could potentially increase the risk of infections.
