FREE CSSD Sterilization Methods and Infection Control Questions and Answers
Aseptic processing (Select all that apply):
Please select 2 correct answers
Explanation:
Aseptic processing refers to a method of manufacturing that aims to prevent contamination of a product during its production. It involves creating and maintaining a sterile environment to minimize the risk of microbial contamination. However, aseptic processing does not have the capability to remove or kill microorganisms that may already be present in the materials used. Therefore, it can only provide assurance that the product does not become contaminated during the manufacturing process, but it cannot eliminate or destroy any existing microorganisms.
PH of Acidic solution should be:
Explanation:
The correct answer is 1-5 because pH is a measure of the acidity or alkalinity of a solution. A pH value below 7 indicates acidity, and the lower the pH value, the stronger the acidity. Therefore, a pH range of 1-5 represents a highly acidic solution.
The process of removing visible soil from surgical instruments is called:
Explanation: Decontamination is the process of removing visible soil, debris, and contaminants from surgical instruments. This step is essential before sterilization to ensure that the instruments are clean and safe for patient use. Disinfection and sanitization refer to processes that reduce the number of microorganisms on surfaces but may not necessarily remove visible soil. Sterilization, on the other hand, refers to the complete elimination of all microorganisms, including spores, from an object or surface.
Which sterilization method involves using high-pressure steam to kill microorganisms?
Explanation:
Autoclave sterilization, also known as steam sterilization, involves using high-pressure steam to kill microorganisms on instruments and other items. This method is widely used in healthcare facilities due to its effectiveness and efficiency in sterilizing a wide range of materials.
What is the full form of SAL?
Explanation:
The full form of SAL is Sterility Assurance Level. This term is commonly used in the field of sterilization to indicate the probability of a microorganism surviving on a sterilized product. It is a measure of the effectiveness of the sterilization process and is typically expressed as a logarithmic reduction value. The higher the SAL, the higher the level of sterility assurance.
What is the easiest method of sterilization?
Explanation:
Steam sterilization is considered the easiest method of sterilization because it is highly effective in killing microorganisms, including bacteria, viruses, and spores. It is a simple process that involves exposing the items to high temperatures and pressure, which ensures complete sterilization. Steam sterilization is widely used in healthcare settings, laboratories, and industries due to its efficiency, reliability, and ease of use. Additionally, it is a cost-effective method and does not require the use of chemicals, making it a safe and environmentally friendly option for sterilization.
What is the act of maintaining sterility during procedures called?
Explanation:
The aseptic technique refers to the practice of maintaining sterility during procedures. This involves using sterile equipment, following proper hand hygiene, and creating a sterile field to prevent the introduction of microorganisms. By adhering to the aseptic technique, healthcare professionals can minimize the risk of infections and ensure the safety of patients undergoing procedures.
The time to kill 90% of bacterial spores in a given population is called ____________ value.
Cavitation is related to:
Explanation:
Cavitation is related to Ultrasonic Cleaning. Ultrasonic cleaning uses high-frequency sound waves to create tiny bubbles in a cleaning solution. These bubbles then collapse rapidly, creating a cleaning action called cavitation. The collapse of these bubbles generates high temperatures and pressures, which effectively remove dirt, grease, and contaminants from the surfaces being cleaned. This process is particularly effective for cleaning delicate or intricate items where traditional cleaning methods may not be suitable.
An example of a sterilant is:
Explanation:
All of the given options - water, hydrogen peroxide, and ethylene oxide - can act as sterilants. A sterilant is a substance that is capable of killing or eliminating all forms of microbial life, including bacteria, viruses, and fungi. Water can act as a sterilant by heat sterilization methods such as boiling or steam sterilization. Hydrogen peroxide can be used as a sterilant by its strong oxidizing properties, which can destroy microbial cells. Ethylene oxide is a commonly used sterilant in healthcare settings, as it can penetrate and kill microorganisms even in hard-to-reach areas. Therefore, all of the given options can be classified as sterilants.
Sterilization methods include:
Explanation:
The correct answer is "All of the Above" because sterilization methods include various techniques such as irradiation, heat, and chemical methods. Irradiation involves the use of ionizing radiation to kill microorganisms, heat sterilization involves the application of high temperatures to destroy microorganisms, and chemical sterilization involves the use of chemicals to kill or inhibit the growth of microorganisms. Therefore, all three methods mentioned in the options are valid sterilization methods.
