Asepsis refers to the practice of eliminating contaminants in medical or surgical environments. Even though intact skin is a good barrier against microbial contamination, a patient can become colonized with microbes if appropriate precautions are not taken. Education and training are critical elements of asepsis and infection control because they facilitate appropriate decision-making. Thus, many of the aseptic techniques will be asked about during the exam.
