Practice Test For The CRCST Certification Exam

Healthcare workers have a duty to report incidents or accidents involving patients because it is essential for patient safety and quality of care. Reporting allows for proper investigation, analysis, and implementation of corrective measures to prevent future occurrences. It also promotes transparency and accountability within the healthcare system. By reporting incidents, healthcare workers contribute to a culture of learning and continuous improvement, ultimately benefiting patient outcomes. Therefore, it is indeed the responsibility of all healthcare workers to report such incidents or accidents involving patients.

A plane crash is considered an external disaster because it is an event that occurs outside of an individual's control and affects a large number of people. It is an unexpected and tragic incident that can cause significant loss of life and property damage. The impact of a plane crash extends beyond the immediate victims and can have far-reaching consequences for families, communities, and even countries. Therefore, the statement that a plane crash is an example of an external disaster is true.

Most states require that ethylene oxide be vented into an emission control device to prevent the gas from entering the atmosphere. This is because ethylene oxide is a hazardous gas that can cause various health problems and environmental damage. Venting it into an emission control device helps to capture and treat the gas before it is released into the air, reducing the risk of pollution and harm to human health. Therefore, the statement is true.

Ethylene oxide gas canisters should be stored in a chemical storage cabinet because this type of cabinet is specifically designed to safely store hazardous chemicals. It is equipped with features such as ventilation systems, spill containment, and fire-resistant materials to minimize the risk of accidents or exposure to the gas. Storing the canisters in an appropriate container or secondary container may not provide the same level of protection and could potentially pose a safety hazard. Discarding the canisters without proper storage can also be dangerous, as they may still contain residual gas that could be released and cause harm.

Ergonomic injuries are a risk factor for persons who perform repetitive or physical work. This means that individuals who engage in tasks that involve repetitive movements or physical labor are more susceptible to experiencing ergonomic injuries. These injuries can result from the strain and stress placed on the body due to the nature of the work being performed. Therefore, it is important for individuals in such roles to take necessary precautions and implement ergonomic practices to minimize the risk of injury.

The correct answer is "Wash all disposable sharps before discarding them." This is not required for Sharps Safety because disposable sharps are meant to be discarded after use and should not be washed. Washing them can increase the risk of injury and contamination. It is important to dispose of all single-use sharps in an appropriate container, never use fingers to remove a blade from a scalpel, and separate reusable sharps from other instruments when processing to ensure Sharps Safety.

Material Safety Data Sheets (MSDS) are provided by the product manufacturer. MSDSs contain important information about the potential hazards of a product, including its chemical composition, physical properties, and safety precautions. They are essential for ensuring the safe handling, storage, and use of a product. It is the responsibility of the product manufacturer to provide accurate and up-to-date MSDSs to inform users about the potential risks associated with their products.

PPM stands for parts per million, which is a unit of measure commonly used to describe the concentration or amount of a substance in the air. In this case, it is used to describe the amount of EtO (Ethylene Oxide) in the air. PPM is a widely used unit for measuring air pollution, gas concentrations, and chemical levels in various industries and environmental studies.

Secondary containers of chemicals must be labeled with a copy of the original manufacturer's label or a generic label that identifies hazard warnings and directions. This is important for ensuring that anyone handling the chemicals is aware of the potential hazards and knows how to safely use and store them. By having the appropriate labeling on secondary containers, it helps to prevent accidents, injuries, and potential exposure to harmful substances.

In a class C fire, the burning material is energized electrical equipment. This means that the fire is caused by an electrical source, such as faulty wiring or overloaded circuits. It is important to use appropriate fire extinguishers and techniques to safely extinguish this type of fire, as water or other conductive substances can increase the risk of electrical shock. It is crucial to cut off the power supply before attempting to extinguish the fire to ensure safety.

Disposable items, such as gloves, masks, gowns, and other medical supplies, can increase the combustible load in a healthcare facility. These items are often made of materials that are flammable or can easily catch fire, such as plastic or paper. When these items are not disposed of properly or are stored inappropriately, they can contribute to the overall combustible load in the facility. This can increase the risk of fire and make it more difficult to control or extinguish a fire if one occurs. Therefore, the statement that disposable items increase the combustible load in a healthcare facility is true.

The information that is NOT included on a Material Safety Data Sheet (MSDS) is the required inventory levels. An MSDS provides important safety information about a hazardous substance, including special precautions, physical data, and product identification. However, it does not typically include information about the required inventory levels of the substance. This information is usually managed separately by the organization or company handling the substance.

Polymerization is the correct answer because it refers to a molecular reaction that creates an uncontrolled release of energy. During polymerization, small molecules called monomers combine to form a larger molecule called a polymer. This process can release a significant amount of energy, especially if it is not properly controlled or if the reaction becomes uncontrollable. Therefore, polymerization fits the description of a molecular reaction that creates an uncontrolled release of energy.

Pushing the cart instead of pulling it when transporting sterilized items from the ethylene oxide sterilizer to the aerator is not necessary to avoid inhaling ethylene oxide fumes. The method of transportation, whether pushing or pulling, does not affect the inhalation of fumes. Therefore, the statement is false.

Type B fire extinguishers should be used on flammable liquids. Flammable liquids include gasoline, oil, grease, and other similar substances. Type B fire extinguishers are specifically designed to extinguish fires caused by flammable liquids by using agents such as foam or dry chemical powders. Class A fire extinguishers are suitable for ordinary combustible materials like wood, paper, and cloth, while Class C fire extinguishers are used for electrical fires. Therefore, Type B is the correct answer for this question.
