Dental Radiology Chapter 15 Review Questions with Complete Solutions What is the primary purpose of sterilization in radiology? Sterilization in radiology is used to eliminate all microbial life from instruments and equipment to prevent the transmission of infections to patients and staff. What are the most common pathogens that can be transmitted in a radiology environment? Common pathogens include bacteria (e.g., Staphylococcus aureus), viruses (e.g., Hepatitis B, HIV), and fungi, which can be transmitted via contaminated surfaces or instruments. What is the difference between sterilization and disinfection in radiology? Sterilization eliminates all microbial life, while disinfection reduces or destroys pathogens but may not eliminate all microorganisms. Why is hand hygiene essential in radiology procedures? Proper hand hygiene helps reduce the risk of pathogen transmission between patients and radiology staff by preventing cross-contamination. 2 What is the role of personal protective equipment (PPE) in radiology? PPE, including gloves, masks, gowns, and eye protection, is used to protect radiology personnel from exposure to bloodborne pathogens, infectious materials, and contaminants. What is the recommended method for disinfecting radiology equipment between uses? Disinfection involves wiping down equipment with hospital-grade disinfectants that are effective against bloodborne pathogens, ensuring a clean surface for each patient. What is the proper procedure for cleaning and disinfecting a radiographic imaging room? The room should be cleaned thoroughly with disinfectant wipes, focusing on high-touch surfaces like control panels, chairs, and positioning devices to reduce the risk of infection. What are high-touch surfaces in a radiology department? High-touch surfaces include X-ray machine controls, positioning devices, computer keyboards, and door handles, which should be disinfected regularly to prevent pathogen spread. How can pathogens be transmitted through radiology equipment? 3 Pathogens can be transmitted through direct contact with contaminated equipment, such as X-ray machines, positioning devices, or imaging receptors, if proper sterilization or disinfection procedures are not followed. What is the best way to prevent cross-contamination between patients in a radiology setting? Using single-use items, cleaning and disinfecting equipment between patients, and following strict infection control protocols help minimize cross-contamination risks. What steps should be taken to prevent the spread of infection when handling X-ray films or digital sensors? Handling X-ray films or digital sensors with gloves, using barriers, and ensuring proper cleaning and sterilization of reusable items can prevent the spread of infection. What is the purpose of barrier techniques in radiology? Barrier techniques, such as using plastic wraps or covers, prevent direct contact with surfaces that may be contaminated, reducing
