Medical asepsis - ANS practices and procedures to reduce the risk of infection
some are:
hand hygiene, environmental cleaning, barrier techniques
isolation precautions - ANS eliminate or reduce infection transmission from one person to
another
surgical asepsis - ANS sterile technique to prevent infection of a surgical wound that includes
procedures to prohibit the presence of pathogens from the patient, medical personnel,
equipment and surgical environment
standard precautions - ANS a group of infections prevention practice that patients regardless
of suspected or confirmed infection status
hand hygiene, gloves, gown, mask, face shield or goggles

,pathogens - ANS disease causing agents
transmission-based precautions - ANS measures taken in addition to standard precautions to
interrupt the transmission of pathogens from clients who may be infected or colonized with
certain infectious agents
airborne, droplet, contact
when are standard precautions used and what is the attire - ANS applied to all patients but
used when; with blood, blood products, bodily fluids, secretions, excretions (except sweat), non
intact skin and mucous membranes
hand hygiene, gloves, gown, mask, face shield, goggles, respiratory hygiene, cough ettiequte,
safe injection practices
contact precautions - ANS prevent the spread of diseases transmitted by direct or indirect
contact
droplet precautions - ANS prevent the spread of diseases transmitted by smaller (less than 5
microns) respiratory droplets by an infected person
what are the basic principles for transmission based precautions - ANS -hand hygiene before
entering and leaving the room
-properly dispose of contaminated supplies and equipment
-apply knowledge of mode of transmission when using PPE
-protect all persons from exposure during transport of an infected patient outside the isolation
room
what is direct and indirect contact of contact precautions and what is the PPE used -
ANS direct: the care and handling go contaminated body fluids
2 @COPYRIGHT 2025/2026 ALLRIGHTS RESERVED
, indirect: transfer of an infectious organism through contaminated instruments or hands of
health care workers
gloves and gowns
what are the precautions taken for droplet - ANS stay 3 feet away, hand hygiene and proper
use of PPE
what are airborne precautions and when are they used - ANS when a disease can be
transmitted through air
isolation with negative air flow (HEPA), N95 respirator
what is a protective environment and what does it entail - ANS designed for patients who
have undergone transplant or gene therapy
positive air flow (HEPA), patient should wear a mask if they leave their room at times of
construction, patients are not allowed to have flowers or potted plants in their room
what is the cause of evidence based practice for infections control - ANS -to understand the
factors that nurses adherence with isolation precautions can provide further research into the
effectiveness of training related to isolation precautions. identifying these factors can decrease
the transmission of diseases, which can improve patient outcomes
-to understand nurses perceptions regarding infection prevention and control can provide
further insight into how the education is applied to practice. improving student nurses
adherence to infection prevention techniques will affect patient outcomes
what should I document for infection control? - ANS -infection control measures used
-clean or sterile gloves
-if the patient has latex allergy or sensitivity
