Hand Hygiene Handwashing is the best and most effective way to prevent the spread of infection when it is done correctly and properly. Proper hand washing can be done with friction and regular soap and water or a special alcohol based hand sanitizing antimicrobial solution, for at least 20 seconds.

Handwashing is particularly important in the health care environment for many reasons including the fact that health care facilities are highly prone and susceptible to many health care acquired infections, including those such as like methicillin-resistant staphylococcus aureas MRSAvancomycin resistant enterococcus VRE principles of asepsis, and penicillin resistant streptococcus pneumoniae, which are highly resistant to antimicrobial treatment.

Standard Precautions, Transmission Based, Surgical Asepsis: NCLEX-RN

Please note, although special alcohol based hand sanitizing antimicrobial solutions are effective against most pathogenic microorganisms, they are not effective against Clostridium difficile C.

Handwashing is done using friction for a minimum of twenty seconds before and after each client contact, in addition to other times such as before and after donning and removing gloves. Alcohol based hand cleansers are not a substitute for good handwashing, however, they can be used when running water and soap are not accessible.

Alcohol based handwashing products are liberally applied to the entire hand after which the hands are rubbed until the entire hand is dried completely. Principles of asepsis precautions protect health care workers and patients from the spread of infection secondary to contaminated blood and other bodily fluids.


Special Transmission Precautions and Isolation Contact precautions prevent direct and indirect contact transmissions of infectious pathogens like those found in infected wounds, infectious diarrhea, and infections principles of asepsis as herpes simplex; droplet precautions are used to prevent the transmission of pathogens that are transmitted with a cough or sneeze, therefore, face masks are indicated for these precautions; and airborne precautions are used for airborne transmission microbes like tuberculosis which requires a negative pressure private room and a HEPA mask.

Principles of asepsis Protective Equipment The use of personal protective equipment protects the health care staff, clients and visitors against infections. Personal protective equipment PPE is specialized equipment and attire that is used by employees in health care to protect against infections.

Examples of personal protective equipment include gowns, gloves, masks, goggles and respirators. Some basic principles for donning and removing personal protective equipment include donning sterile gowns and gloves using surgical technique by touching only the sterile surfaces of these items with sterile hands.

For example, the first sterile glove is applied by touching the inside of the glove with the bare hand after which the second sterile glove is donned by holding the glove with the sterile gloved hand without touching any skin surfaces.

Another basic principle includes removing used personal protective equipment by folding the item inside out and disposing of it in the proper receptacle.

Using Appropriate Technique to Set up a Sterile Field principles of asepsis Maintaining Asepsis These basic sterile asepsis procedures are principles of asepsis for setting up and maintaining a sterile field.


Sterile items ONLY are placed principles of asepsis the sterile field. Coughing or sneezing over the sterile field contaminates the sterile field. The nurse must maintain a one inch border around the sterile field that is not sterile.

All sterile items and supplies are put inside of this one inch border. The sterile field must remain dry; any wetness or moisture contaminates the sterile field.

Sterile liquids must be poured carefully into sterile containers on the sterile field without the solution running over and obliterating the label on the bottle.

Principles of asepsis - science sharing

Sterile masks are also indicated, particularly when there is a possibility that a person will be working with or near the sterile field.

Whenever these things are NOT done and maintained continuously throughout the treatment or procedure, the entire sterile field and its contents are promptly discarded because the sterile field is no longer sterile. The entire set up principles of asepsis be redone from the very beginning.

Following the Correct Policy and Procedures When Reporting a Client With a Communicable Disease All states have laws and regulations that mandate the reporting of communicable diseases, most of which must also be reported to the Centers of Disease and Prevention.

The purpose of this reporting is to facilitate the tracking and trending of communicable diseases and epidemics in order to reverse the threat and to prevent future outbreaks. Consider the rim of bottles unsterile.

There was a problem providing the content you requested

Never touch equipments on rims of bottles. Before using the sterile content pour a little amount to clean the rim of its container.


Sterile persons keep within the sterile area. Non-sterile persons keep away from sterile area. Sterile persons keep contact with sterile area to a minimum.
