1.
Which of these is not an aseptic procedure?
Correct Answer
C. Mastectomy
Explanation
Mastectomy is not an aseptic procedure because it involves the removal of breast tissue, which is a surgical procedure. Aseptic procedures are those that are performed under sterile conditions to prevent the introduction of harmful microorganisms. Bandaging, wound stitching, and catheterization are all examples of aseptic procedures as they involve the use of sterile materials and techniques to minimize the risk of infection.
2.
Which of these medical equipments is not reusable?
Correct Answer
D. Rubber gloves
Explanation
Rubber gloves are not reusable because they are meant to be used once and then discarded. They are used to maintain hygiene and prevent the spread of germs during medical procedures. IV pumps, crash carts, and surgical instrumentation, on the other hand, can be sterilized and reused multiple times as they are made of durable materials and undergo proper cleaning and disinfection processes.
3.
Which of these is not used to ensure high level of disinfection?
Correct Answer
B. Sucrose solution
Explanation
Sucrose solution is not used to ensure a high level of disinfection. Sucrose is a type of sugar and does not have disinfectant properties. Hydrogen peroxide plasma, paraceacetic solution, and glutaldehyde solution are commonly used disinfectants in various industries and medical settings.
4.
Which of these is not a factor that determines the method of sterilization?
Correct Answer
B. Desired level of sterilization
Explanation
The desired level of sterilization is not a factor that determines the method of sterilization. Factors such as operational cost, efficacy, and time are taken into consideration when choosing a sterilization method. The desired level of sterilization may vary depending on the specific requirements of the situation, but it does not directly determine the method used.
5.
Which of these is not a division of sterility services?
Correct Answer
C. Assembly processing
Explanation
Assembly processing is not a division of sterility services because it involves the putting together or assembling of different components or parts, rather than the sterilization or decontamination of medical equipment or instruments. The other options, decontamination, distribution, and sterilization and storage, are all activities that are directly related to maintaining sterility and cleanliness in healthcare settings.
6.
What is the easiest method of sterilization?
Correct Answer
A. Steam sterilization
Explanation
Steam sterilization is considered the easiest method of sterilization because it is effective in killing microorganisms and spores. Steam can penetrate and reach all areas of the object being sterilized, ensuring thorough sterilization. It is also a relatively quick process and does not require the use of chemicals, making it safe and environmentally friendly. Additionally, steam sterilization can be easily controlled and monitored, ensuring consistent and reliable results.
7.
Which of these does not need to be sterilized?
Correct Answer
B. Syrindge
Explanation
A syringe does not need to be sterilized. While scalpels, hypodermic needles, and artificial pacemakers must be sterilized to prevent the transmission of infections, syringes are typically disposable and are used only once before being discarded. Therefore, there is no need for them to be sterilized.
8.
What is the act of maintaining sterility during procedures called?
Correct Answer
C. Aseptic technique
Explanation
Aseptic technique refers to the practice of maintaining sterility during procedures. It involves taking precautions to prevent the introduction of microorganisms into a sterile area or preventing the transfer of microorganisms from a contaminated area to a sterile area. This is achieved by using sterile equipment, wearing protective clothing, and following strict protocols to minimize the risk of infection. Aseptic technique is commonly used in medical and laboratory settings to ensure the safety and effectiveness of procedures.
9.
Which of these methods of sterilization does not involve electromagnetic radiation?
Correct Answer
B. Sterilization by Subatomic particles
Explanation
Sterilization by Subatomic particles does not involve electromagnetic radiation. Subatomic particles refer to particles that are smaller than an atom, such as protons, neutrons, and electrons. While electron beams, gamma rays, and X-rays all involve electromagnetic radiation, sterilization by subatomic particles may involve other methods such as using high-energy particles to destroy microorganisms without the use of radiation.
10.
What method of sterilization is most suitable for fluids that can be destroyed by heat?
Correct Answer
A. Microfiltration
Explanation
Microfiltration is the most suitable method of sterilization for fluids that can be destroyed by heat. This method involves passing the fluid through a microfilter that has small pores, which can effectively remove microorganisms and particles from the fluid without subjecting it to high temperatures. This is ideal for heat-sensitive fluids that may be damaged or degraded by traditional heat sterilization methods such as wet heat or dry heat. Radiation sterilization may also be an option, but it is typically used for solid materials rather than fluids.
