IAHCSMM 8th Edition Progress Test 2

The decontamination area should have negative air flow in relation to the other areas of the department. This means that the air pressure in the decontamination area should be lower than in the surrounding areas. This is important because it helps to prevent the spread of contaminants from the decontamination area to other areas of the department. By maintaining negative air flow, any airborne particles or contaminants in the decontamination area will be drawn into the area and not allowed to escape into other areas.

The statement is true because MSDS (Material Safety Data Sheet) provides crucial information about the potential hazards of a material, such as its chemical composition, physical properties, and safe handling procedures. This information is essential for employees to understand and follow in order to ensure their safety while working with hazardous materials.

The decontamination area of the Central Service department should have negative air flow to prevent the spread of contaminants. Negative air flow means that the air pressure in the area is lower than the surrounding areas, which ensures that any airborne contaminants are drawn into the decontamination area and not released into other parts of the facility. This is crucial in a biohazard area to maintain a safe and controlled environment for handling potentially infectious materials.

Proper handling of instrumentation is crucial to ensure patient safety and prevent contamination or damage to the instruments. It is not solely the responsibility of one individual or role, such as the surgeon, scrub technician, or central service technician. Instead, it is the responsibility of everyone who comes in contact with the instrumentation, including all healthcare professionals involved in the surgical or medical procedure. This includes not only handling the instruments properly during use but also cleaning, sterilizing, and storing them correctly to maintain their integrity and prevent infections.

The U.S. Food and Drug Administration is responsible for ensuring food, drugs, and cosmetics are safe for use. This means that the FDA has the authority to regulate and oversee the production, distribution, and sale of these products to ensure they meet safety standards and do not pose any health risks to consumers. The FDA conducts inspections, reviews data and research, and sets regulations to ensure the safety and effectiveness of food, drugs, and cosmetics in the market.

This statement is true because cleaning refers to the removal of dirt, dust, and debris from a surface, while sterilizing refers to the process of killing or eliminating all forms of microorganisms, including bacteria, viruses, and fungi. Cleaning is a necessary step before sterilizing because if a surface is not clean, the sterilization process may not be effective. However, it is possible to clean a surface without sterilizing it, as cleaning alone can help remove visible dirt and maintain hygiene.

The statement is stating that the amount of Eto (ethylene oxide) that remains inside materials after sterilization is referred to as the residual. This implies that the statement is true.

Chemical indicators are used to determine whether the sterilization process has been effective. They are often placed inside sterile packages and change color when exposed to certain conditions, such as heat or steam. By including chemical indicators in the packaging, users can quickly and easily verify if the package has been properly sterilized before using the contents. Therefore, it is true that chemical indicators are often the first performance test the user sees upon opening a sterile package.

Automatic washers clean using a spray-force action called impingement. This means that the washers use a powerful spray of water or detergent to forcefully hit the surface being cleaned, effectively removing dirt and grime. This spray-force action helps to dislodge and remove stains and debris from the objects being washed, making the cleaning process more efficient and effective. Therefore, the statement "Automatic washers clean using a spray-force action called impingement" is true.

Jargon refers to specialized words or phrases that are commonly used within a particular profession or field. These terms are often understood only by those working in that specific position or industry. Therefore, the statement that specialized words or phrases known only by persons working in a position is known as Jargon is true.

Cleaning refers to removing dirt, dust, and debris from a surface, while disinfecting refers to killing or inactivating germs and bacteria on that surface. It is possible to clean a surface without disinfecting it, as cleaning alone can make it visually clean. However, disinfecting without cleaning is not effective because the presence of dirt and debris can reduce the effectiveness of the disinfectant. Therefore, the statement "One can clean without disinfecting, but one cannot disinfect without cleaning" is true.

The correct answer is "at point of use." This means that decontamination of instruments and equipment starts immediately when the instruments are placed back in their trays at the point of use. This ensures that the instruments are clean and ready for the next use, preventing the spread of infections or contaminants.

The USP-NF (United States Pharmacopeia-National Formulary) does indeed provide guidelines and requirements for packaging purified water. These guidelines ensure that the packaging materials used do not contaminate the water and maintain its purity. Therefore, the statement is true.

Risk management involves methods used to assess the risks of a specific activity and to develop a program to reduce losses from exposure to them. It is a systematic process that includes identifying, analyzing, and evaluating potential risks, as well as implementing strategies to mitigate or control those risks. This helps organizations to make informed decisions and take necessary actions to minimize the impact of risks on their operations and objectives. Ergonomics and central supply are not directly related to assessing and reducing risks, so they are not the correct answers.

The process monitors for Quality Assurance in EtO include the "4 R's": Run, Read, Record, and Retain. Retaining refers to the practice of keeping records or documentation of the process for future reference or analysis. This helps ensure traceability and accountability in the quality assurance process.

Hydrogen peroxide is not as effective as ethylene oxide (EtO) in terms of penetration capabilities and solubility in most materials. This suggests that the statement is true.

A CS tech would use a plastic dowel rod to test the sharpness of chisels and osteotomes. A plastic dowel rod is a tool that can be used to check the sharpness of the cutting edges of surgical instruments. By running the edge of the chisel or osteotome along the plastic dowel rod, the tech can determine if the instrument is sharp enough for use. This method allows the tech to ensure that the instruments are in proper working condition and can effectively perform their intended tasks.

The statement is true because in pre-vacuum cycles, both non-porous and porous items can be sterilized as long as the appropriate times and temperatures are used for each. This means that items such as wraps, pouches, or containers can effectively sterilize both types of items, ensuring that they are free from any microorganisms or contaminants.

The statement is true because dry heat sterilization is commonly performed at a temperature of at least 320 degrees Fahrenheit for a duration of two hours. This high temperature is necessary to kill microorganisms and ensure the sterilization process is effective. Dry heat sterilization is often used for items that cannot be sterilized using other methods, such as heat-sensitive materials.

EtO (Ethylene Oxide) is a hazardous substance commonly used in sterilization processes in healthcare facilities. To ensure the safety of employees who handle EtO, it is necessary to monitor their exposure to this chemical. The statement states that EtO Personnel Monitoring records should be kept for 30 years after an employee has finished their last EtO-related task. This is important because it allows for long-term tracking and analysis of an employee's exposure history, which can be useful for identifying potential health risks and ensuring compliance with safety regulations. Therefore, the answer "True" is correct.

Passivation is a chemical process used in instrument manufacture to create a corrosion-resistant finish by forming a thin transparent oxide film. This film acts as a protective barrier against corrosion, preventing the instrument from being damaged by exposure to moisture or other corrosive substances. It helps to extend the lifespan of the instrument and maintain its functionality. Pastuerization is a process used to kill bacteria in food by heating it to a specific temperature, while Polymorphisate is not a recognized term in relation to instrument manufacture. Therefore, the correct answer is Passivation.

The appropriate type of fire extinguisher to use when the fire involves flammable liquid is type B. Flammable liquids include gasoline, oil, and alcohol, and they require a fire extinguisher that can effectively extinguish fires caused by these substances. Type B fire extinguishers are specifically designed to handle flammable liquid fires and use extinguishing agents such as foam or dry chemical powder to smother the flames and prevent reignition.

Polymerization is the correct answer because it refers to a molecular reaction in which smaller molecules, called monomers, combine to form a larger molecule, known as a polymer. This reaction typically releases energy in a controlled manner. In contrast, molecular fission and molecular fusion do not involve the creation of polymers and are not associated with uncontrolled energy release. Therefore, they are not the correct answers.

EtO inactivates microbes by a process called alkylation, which involves the transfer of an alkyl group from EtO to specific proteins in microbes. This reaction disrupts the structure and function of these proteins, ultimately leading to the inactivation of the microbes.

Point-of-use preparation and transport aims to prevent cross contamination. This is achieved by ensuring that instruments are properly cleaned and decontaminated at the point of use, before they are transported back to the Central Service. By doing so, the risk of spreading infections or contaminants from one area to another is minimized, ultimately promoting a safer and more hygienic environment.

Flash sterilization is not the process of sterilizing a packaged item. Flash sterilization is a method used to sterilize unwrapped or unpackaged instruments, where the sterilization process is accelerated to a shorter duration. It is typically used in emergency situations when immediate use of the sterilized instruments is necessary. Packaging is an essential part of the sterilization process to maintain the sterility of the item until it is ready for use. Therefore, the statement is false.

The Department of Veteran's Affairs has its own certification programs, which means that they do not adhere to the guidelines set by AAMI (Association for the Advancement of Medical Instrumentation). Therefore, the statement is true.

Glucagon is a hormone that increases the blood sugar level. It is released by the pancreas when blood sugar levels are low, and it acts to stimulate the liver to release stored glucose into the bloodstream. Therefore, the statement that glucagon decreases the blood sugar level is incorrect.

Psychrophiles are bacteria that thrive in cold temperatures. They have adapted to survive and reproduce in environments such as glaciers, polar regions, and deep ocean waters. These bacteria have specific enzymes and proteins that allow them to function optimally in cold conditions. Thermophiles, on the other hand, prefer high temperatures, while mesophiles have an optimum temperature range similar to that of humans. Therefore, the correct answer is psychrophiles, as they are specifically adapted to grow in cold environments.

Insulin is a hormone that decreases the level of sugar in the blood. It is produced by the pancreas and helps regulate blood sugar levels by allowing cells to take in glucose from the bloodstream. Therefore, the statement that insulin increases the level of sugar in the blood is false.

Pre-vacuum flash cycles are indeed standard sterilization cycles with a limited drying time. Unlike gravity flash cycles, which rely on gravity to remove air and steam from the sterilization chamber, pre-vacuum flash cycles use a vacuum pump to actively remove air and steam. This allows for faster and more efficient sterilization. The limited drying time is necessary to prevent damage to the sterilized items and to ensure their safety for use. Therefore, the statement is true.

To unload a sterilizer, the door should be cracked open. For a vacuum unit, it is recommended to wait 10 minutes to ensure proper evaporation and drying. However, for a gravity sterilizer, it is advised to wait 25 to 30 minutes for the same purpose. Therefore, the correct answer is 10 and 25 to 30.

SFPP stands for Steam Flush Pressure Pulse, which is a style of sterilizer that uses a repeated sequence of steam flush and pressure pulse to remove air from the sterilizer chamber. This process helps to ensure that the materials being sterilized are properly treated and free from any contaminants. Gravity Air and Dynamic Air are not specific sterilization methods, while Flash is not mentioned in the given explanation.

An endemic disease refers to a disease that is constantly present and prevalent within a specific population or geographic area. Unlike an epidemic, which is characterized by a sudden increase in the number of cases, an endemic disease maintains a relatively stable and predictable level of occurrence. Therefore, the correct answer is "Endemic" as it accurately describes a disease that occurs continuously within a community.

Parenteral solutions are a type of sterile solution that are administered directly into the body, bypassing the digestive system. These solutions are typically given through injections, intravenous infusions, or other methods that allow for direct delivery into the bloodstream. In contrast, external solutions refer to sterile solutions that are used externally, such as for wound irrigation or cleaning. Therefore, the correct answer is parenteral, as it accurately identifies one of the two types of sterile solutions mentioned in the question.

The correct answer is "Rapid Heat transfer." In dental offices, two basic types of dry heat sterilizers are used: oven type and rapid heat transfer. The rapid heat transfer sterilizers are designed to quickly and efficiently transfer heat to the instruments, ensuring effective sterilization. This type of sterilizer is commonly used in dental offices to sterilize instruments and equipment.

The process of sterilizing an item that is not packaged is not known as Terminal Sterilization. Terminal Sterilization refers to the process of sterilizing items that are packaged and sealed, typically in a healthcare or laboratory setting. Sterilizing an item that is not packaged may involve other methods such as disinfection or autoclaving, but it would not be referred to as Terminal Sterilization.

Sterilization process indicators are used to confirm that a package has undergone the sterilization process correctly. They serve as the initial indication of any errors that may have occurred during the process. These indicators are essential in ensuring the effectiveness of sterilization and maintaining the safety of the package contents.

Chelating agents are chemicals that have the ability to bind with and hold onto hard water minerals, such as calcium and magnesium, in a solution. By doing so, they prevent these minerals from reacting with soaps or detergents, which allows them to function effectively. Sequestering agents also serve a similar purpose, but wetting agents are substances that reduce the surface tension of liquids, making them spread more easily. Therefore, the correct answer is chelating agents.

If the Flash sterilization load consists of a single instrument comprised of metal and without lumens, a 3-minute cycle at 270°F (132°C) should be used. This is because flash sterilization is a rapid sterilization process used for urgent situations, and a shorter cycle time is sufficient for sterilizing a single instrument without lumens. The high temperature of 270°F helps to kill any microorganisms present on the instrument effectively within a shorter time frame.

The Express cycle is preset by the manufacturer for 4 minutes at 270deg F with 3 minutes of trying time and a total cycle of 12 minutes.

The statement is true because there is no specific national recommendation or requirement for how long the Central Sterile Department needs to maintain cycle records. The length of time for maintaining these records may vary depending on local regulations, hospital policies, and other factors. Therefore, it is up to the individual department or facility to determine the appropriate duration for retaining cycle records.

Ozone is a gas that is generated within the equipment itself, meaning that there is no need to handle sterilant containers when using Ozone Sterilizers. This is because the equipment has the capability to produce ozone, which is used for sterilization purposes. Therefore, the statement is true.

The statement suggests that the Express cycle is a just-in-time process and has a shelf life. However, the correct answer is False. This means that the Express cycle is not a just-in-time process and does not have a shelf life.

The correct answer is "None of the above." This means that all of the options listed - vibration, repetition, and awkward positions - are ergonomic stressors. Ergonomic stressors refer to factors in the workplace that can cause physical strain or discomfort, often leading to musculoskeletal disorders. Vibration, repetition, and awkward positions are all examples of common ergonomic stressors that can negatively impact a person's health and well-being in the long run.

The correct answer is "activities that prevent infection". This is because aseptic technique refers to a set of practices and procedures that are used to prevent the contamination of sterile areas or objects. These activities include measures such as hand hygiene, wearing personal protective equipment, using sterile equipment, and maintaining a clean and sterile environment. By following these activities, healthcare professionals can minimize the risk of introducing harmful microorganisms and prevent infections in both patients and themselves.

Sequestering agents are chemicals that are used to remove or inactivate hard water minerals. They work by binding to the minerals and preventing them from causing issues such as scale buildup or interfering with the effectiveness of cleaning agents. Chelating agents, on the other hand, are specifically designed to bind with metal ions, while wetting agents are used to reduce the surface tension of water and improve its ability to spread and penetrate surfaces. Therefore, the correct answer in this case is sequestering agents.
