California Registered Dental Assistant (RDA) Written Practice Exam

According to the CDC, sterilization monitoring records should be kept for as long as required by state and local regulations. While option A may seem like a reasonable answer, it is not specified by the CDC and may differ depending on the practice's location. Option C is too short of a time period, as sterilization monitoring records are important for tracking the safety and effectiveness of sterilization practices over a longer period of time. Option D is also too short and does not comply with CDC guidelines. Therefore, option B is the best answer as it accounts for variations in state and local regulations while also aligning with CDC recommendations.
