EMT Medical Terminology Practice Test

Preventing contamination during wound care and handling equipment is accomplished through aseptic technique. This approach uses sterile methods and barriers to keep the wound and instruments free of pathogens, helping prevent infection. It includes maintaining a sterile field, proper hand hygiene, using sterile gloves and drapes, and ensuring instruments are sterile so that anything that contacts the wound remains free of contaminants. While related terms exist—sterilization means destroying all microorganisms and spores, disinfection reduces harmful organisms on surfaces, and cleaning removes visible soil—these describe different levels of decontamination. Aseptic technique specifically targets preventing contamination in the first place.
