A nurse who serves on an infection control committee is assessing the adequacy of environmental controls against infection.
What does the nurse know to be the first line of defense in medical asepsis?
Isolation or barrier procedures.
Standard precautions.
Hand hygiene techniques.
Routine cleaning of client rooms.
The Correct Answer is C
Hand hygiene techniques are the first line of defense in medical asepsis because they prevent the transmission of microorganisms from one person or object to another. Hand hygiene techniques include washing hands with soap and water or using an alcohol-based handrub.
Choice A is wrong because isolation or barrier procedures are not the first line of defense in medical asepsis, but rather a way of preventing the spread of infection to other patients or health care workers when a patient has a known or suspected infection.
Choice b is wrong because the nature of detergent used on the unit is not the first line of defense in medical asepsis, but rather a factor that affects the effectiveness of cleaning and disinfection of surfaces and equipment.
Choice D is wrong because the ventilation system type is not the first line of defense in medical asepsis, but rather a factor that affects the quality of air and the risk of airborne transmission of microorganisms.
