VRE infection - ✔✔-Vancomycin-resistant entercoccus
-intestinal in origin
-significant threat to high risk clients
--hospitalized
--critically ill-ICU
--oncology patients
--dialysis
--immune disorders
--those who have received multiple antibiotics
--extended hospital stays
**dangerous
What are contact precautions? - ✔✔spreads by direct and indirect contact with patient and their
environment
-draining wounds, secretions, supplies
-precautions include: private room or cohort patients )pt. w /same problem), gown and glove use,
disposal of contaminated items in room
-dedicated equipment
What are defenses against infection? - ✔✔-normal floras (help kill other bacteria that gets on body;
microorganisms that don't cause problems
-body system defenses (blinking, crying)
-inflammation
-vascular and cellular responses (if organisms stay where they are supposed to be, everything will be
okay)
What are droplet precautions? - ✔✔-spread via moist droplet
--transmission via coughing, sneezing (suspend up to 3 ft), touching contaminated objects
-precautions include; private room or cohort patients, mask respirator ex: if you bring a pt. to an x-ray
from isolation give them a mask to wear on the way
What are influencing factors? - ✔✔-not well nourished
-exhausted
-stressed
-smokers
-medications
What are sites that can predispose patients to infection? - ✔✔-surgical wounds
-respiratory tract
-genitourinary tract
-invasive devices
-bloodstream ---always have clean skin
-venipuncture sites
-total parenteral nutrition therapy (TPN) --gives nutrition through IV
-implanted prosthetic devices
What are some risk factors that make a person more susceptible to disease? - ✔✔-very old and very
young
-at risk...chronic diseases
, -diabetes
-immunodeficiency
What are the interventions? - ✔✔-hand hygiene (most important)
-personal protective equipment
-standard precautions
-isolation
What are the modes of transmission--contact? - ✔✔-direct (physical contact ex: shaking hands with
someone who is sick)
-indirect (infectious agent deposited on object/surface ex: someone touches table after sick person
leaves dirty tissues)
-droplet (coughing, sneezing, or during suctioning ex: breathing dirty air, someone coughs in your face)
what are the modes of transmission--non contact? - ✔✔-airborne (droplet nuclei suspended in air
that contain organisms, suspended in air for a longer period of time)
-vehicle (single contaminated source spreads the infection ex: AIDS..some goes out of the country and
has sex with someone with AIDS and brings it back and spreads it around the US)
-vector-borne (transmission by insect or animals (lyme disease, rabies)
What do you do while working in isolation rooms? - ✔✔-delegation
-equipment (take only what is necessary, make sure you don't forget anything, be organized!!)
-PPE disposal
-hand hygiene
-close room door
What does barrier equipment include? - ✔✔-medical asepsis uses barrier equipment to prevent
transmission from infected patient to self or other patients (PPE or PPB)
-sterile asepsis used barrier equipment to prevent transmission from self and environment to patient
-gowns
-masks (regular masks with or without shield)
-goggles
-gloves--clean and sterile
What is ariborne precautions? - ✔✔transmission via exhalation and or ventilation systems
--precautions include..
--private room
--negative pressure room (air is filtered before going to the halls)
--mask or respiratory protection devise N-95 respirator, depending on the condition (TB)
What is hand hygiene? - ✔✔-"foam in, foam out"
-equally effective to hand washing (needs atleast 60%-90% of alcohol)
-cannot be used if hands are visibly soiled
-cannot be used for pts. with C.diff (alcohol doesn't kill spores)
-technique (cover all surfaces of fingers and hands and rubs together until dry)
What is included in personal protective equipment (PPE)? - ✔✔-gloves
-gown
-mask
-eye protection
What is MRSA? - ✔✔-staph infection resistant to beta-lactim antibiotics
-health care associated MRSA (HA-MRSA)
--prevent pathogens in health care facilities
--weakened immune systems
-community associated MRSA (CA-MRSA)
