Answer 1

Principles of surgical asepsis:

-once the equipment and areas free from microorganisms,it must be remain same never contaminate that again.

-touching one non sterile item and touching another sterile item will make contamination..

- never sneeze,cough over a sterile field..

- keep the sterile field dry.

- handle liquids carefully near the sterile field.

-sterile supply should be clearly labelled with content,time and date.

-check expired date always before handing..

- avoid sweeping and dusting when sterile objects are open.

- put mask, apron, gloves before handing sterile equipment..

-wash hands before handing..

Droplet isolation:

Procedures that reduces the risk of droplet- borne infection during coughing, sneezing, talking or performing procedure like suctioning and bronchoscopy.

Contact isolation:

Standard precautions like decrease the infection by microorganisms through direct or indirect contact with the patient who is infected with staphylococcus aureus and clostridium difficile..

Airborne isolation:

Standard precautions that decrease the infection by avoiding infectious agents or dust particles..

Protective isolation:

Standard precautions used in the case of patients with contagious or communicable disease like cancer, HIV etc..

Sterile field:

It is a area considered by free of microorganisms or bacteria..

Isolation precautions:

Equipments used for protecting us from isolations are gloves,mask, gowns, alcohol- based hand rub, single- use towel..

Environmental survey:

Environmental survey performed on a site where there is hazardous substances..The site will be first assessed and planned by environmental engineer or supervisor..Then they will plan for any needs of remedial construction..it also includes monitoring wells and detecting,analyzing and monitoring pollution etc..

This survey useful to avoid spreading any unwanted or contaminated soils, water may cause infection..
