CDA ICE: Prevention of Disease Transmission Which of the following best describes the term "cross-contamination" in the context of a dental office? A. The transfer of pathogens from one surface to another B. Contamination of a sterile instrument during the sterilization process C. The presence of environmental contaminants in the dental operatory D. The mixing of chemical disinfectants leading to reduced efficacy None 14. CDA ICE: Prevention of Disease Transmission Which of the following best defines "sterile" in the context of infection control in a dental setting? A. Free from all forms of microbial life, including spores and viruses B. Lacking pathogenic microorganisms, but not necessarily all microbial life C. Cleaned using a hospital-grade disinfectant D. Sanitized to a level that is generally safe for human contact None 15. CDA ICE: Prevention of Disease Transmission In a dental office, what is the primary reason for using a high-volume evacuator during procedures that generate aerosols? A. To enhance patient comfort by reducing noise B. To minimize the risk of inhalation of airborne particles by the dental team C. To improve visibility in the oral cavity by removing excess moisture D.
