A nursing instructor is teaching the difference between medical and surgical asepsis. Which would be an example of medical asepsis?

• A. Cleaning the hospital environment and equipment routinely
• B. Inserting a urinary catheter for postoperative urinary retention
• C. Changing an abdominal dressing for the first time after surgery
• D. Giving an intramuscular injection in the ventrogluteal region

Answer: (A)

Medical asepsis uses clean technique to reduce the number of pathogens and prevent their spread, primarily through practices like hand hygiene and routine cleaning of the environment and equipment. This kind of cleaning lowers environmental microbial load and infection risk without creating or maintaining a sterile field. Inserting a urinary catheter and changing an abdominal dressing are sterile procedures that require surgical asepsis to prevent introducing microorganisms into a sterile body site or a closed wound. An intramuscular injection is performed using clean technique—the equipment is sterile, the skin is antiseptically cleansed, but a sterile field isn’t maintained throughout the procedure—so it’s an example of medical asepsis.
