What distinguishes medical asepsis from surgical asepsis?

• A. Medical asepsis reduces pathogens (clean technique); surgical asepsis eliminates all organisms (sterile technique); CNAs use medical asepsis.
• B. Medical asepsis eliminates all organisms; surgical asepsis reduces pathogens; CNAs use sterile technique.
• C. Medical asepsis is never used by CNAs; surgical asepsis is used by CNAs; both are the same.
• D. Medical asepsis requires sterile equipment; surgical asepsis uses clean technique only.

Answer: (A)

The main idea is the level of cleanliness and the purpose behind the technique. Medical asepsis uses clean techniques to reduce the number of pathogens and limit their spread during routine patient care. This includes practices like thorough handwashing, regular cleaning and disinfection of surfaces, using barriers as needed, and working with non-sterile supplies. The goal is to prevent infections in everyday caregiving.

Surgical asepsis goes further: it aims to keep areas and instruments completely free of any microorganisms, creating a sterile field for procedures that invade sterile body sites or involve open wounds. This requires sterile equipment and techniques, such as sterile gloves, gowns, drapes, and strict avoidance of any contamination.

In practice, CNAs typically perform care using medical asepsis rather than sterile technique, reserving sterile, surgical asepsis for procedures that require a completely sterile environment.
