CRCST Chapter 6 (8th Edition) Review Quiz

Jewelry should not be worn in the Central Service department work areas because they can harbor bacteria. Bacteria can easily get trapped in the crevices of jewelry, making it difficult to clean and increasing the risk of contamination. In a department where cleanliness and hygiene are crucial, wearing jewelry can pose a potential health hazard. Additionally, jewelry can also interfere with the proper functioning of equipment or instruments, making it unsafe to wear in such work areas.

The correct answer is everyone entering the Central Service department. This means that the departmental dress codes apply to all individuals who enter the Central Service department, regardless of whether they are hospital employees, visitors such as sales reps or maintenance personnel, or anyone else. The dress code is not limited to a specific group of people or based on the amount of time spent in the work area.

To protect themselves from splashes and spills, Central Service technicians assigned to the decontamination area should wear fluid-resistant gowns. This is because fluid-resistant gowns are designed to repel liquids, preventing them from soaking through and coming into contact with the technician's skin. This helps to minimize the risk of contamination and potential exposure to hazardous substances during the decontamination process. Double-cloth gowns, blue surgical scrubs, and sterile Operating Room gowns may not provide the same level of protection against liquid splashes and spills.

Biohazard labels/signs should be red/orange in color. This color combination is commonly used to indicate the presence of biohazardous materials or areas. Red is often associated with danger and warning, while orange is used to signify caution. The combination of these colors effectively alerts individuals to the potential hazards and prompts them to take appropriate safety measures.

Asepsis refers to the absence of microorganisms that cause disease. It is a process or technique used to prevent the introduction or spread of infectious agents. It involves maintaining a sterile environment and employing practices such as hand hygiene, sterilization, and disinfection to minimize the risk of infections. Infection prevention and infection control are related terms but not synonymous with asepsis. HIA control is not a recognized term in the context of this question.

The decontamination area of the Central Service department should have negative air flow. This is because negative air flow ensures that air is constantly being pulled out of the area, preventing the escape of any contaminants or biohazardous materials. It helps to maintain a clean and safe environment by preventing the spread of airborne particles to other areas.

During handwashing, it is recommended to lather and scrub the hands for at least 20 seconds. This duration allows enough time for the soap to effectively remove dirt, germs, and other contaminants from the hands. Scrubbing for a shorter period may not adequately clean the hands, while scrubbing for longer periods may dry out the skin. Therefore, 20 seconds is considered an appropriate and sufficient duration for handwashing.

The correct answer is "wet-mopped daily" because the floors in the Central Service department require regular cleaning to maintain cleanliness and hygiene. Wet-mopping daily helps to remove any dirt, dust, or spills that may accumulate throughout the day, ensuring a clean and safe environment for employees and visitors. Sweeping alone may not be sufficient to eliminate all the dirt and debris, so wet-mopping is necessary to achieve the desired level of cleanliness.

Fomites are inanimate objects that can transmit bacteria. They can include items such as doorknobs, cell phones, or clothing, which can harbor and transfer bacteria from one person to another. The term "fomites" is commonly used in the field of epidemiology to describe these objects that can act as vehicles for the transmission of infectious agents. The other options, such as transmission devices, carriers, or framiseals, do not specifically refer to inanimate objects that transmit bacteria.

The main theory of standard precaution is to treat all human blood and bodily fluids as infectious. This means that regardless of whether a patient is in a high-risk category or diagnosed with a specific disease, all blood and bodily fluids should be treated as potentially infectious. This approach helps to minimize the risk of transmission of infections in healthcare settings and ensures the safety of healthcare workers and patients.

The correct answer is the principles of asepsis. Asepsis refers to the practice of preventing the introduction of harmful microorganisms into a sterile environment. The statement in the question emphasizes the importance of knowing what is dirty, clean, and sterile, and taking immediate action to prevent contamination. This aligns with the principles of asepsis, which involve maintaining a sterile environment and preventing the spread of infection. The other options mentioned in the question, such as the Bloodborne Pathogen Standard, infection prevention, and environmental control, are not specifically related to the concept of asepsis.

The Occupational Safety and Health Administration Bloodborne Pathogen Standard requires employers to provide hepatitis B vaccine to employees at no cost, observe standard precautions, and use engineering controls to prevent biohazard exposures. However, it does not specifically mention the requirement to keep biohazard areas locked.

To interrupt the transmission of a causative agent, the most effective method is to eliminate it. This means completely removing or eradicating the causative agent from the environment or item. Sterilizing the item can be a part of the elimination process, but it may not guarantee complete removal of the agent. Wearing appropriate personal protective equipment can help prevent transmission but does not eliminate the agent. Involving the Occupational Safety and Health Administration is not directly related to eliminating the causative agent.

Approximately 700,000 patients develop a healthcare-associated infection each year.

The clean assembly area of Central Service has certain traffic control and dress code requirements that need to be followed. The option "Semi restricted" applies to this area. This means that there are some restrictions in terms of traffic control and dress code, but they are not as strict as the "Restricted" category. Therefore, individuals entering the clean assembly area must adhere to specific guidelines and regulations to maintain cleanliness and safety, but they have slightly more flexibility compared to the restricted areas.
