Infection Control Flashcards
Direct contact
involves spread through touching, shaking hands, kissing, etc
Indirect Contact
implies that an intermediary object (e.g., bedding, used tissues, syringes, drinking cups, etc.) harbors microorganisms and carries them from an infected person to a new person.
Airborne
Transmission through airborne moisture particles (droplets) carrying pathogens. Common colds, upper respiratory infections are spread through sneezing and coughing droplets. Dust particles containing pathogens and spores are also considered airborne transmission
Foodborne
Eating foods improperly refrigerated or cooked leads to food poisoning. Food contaminated with feces or soil also can lead to illness
Waterborne
Feces-contaminated water supply leads to waterborne disease transmission
Vectors
Living carries of pathogens including mosquitos, flies, fleas, ticks, and lice. Vectors spread disease through carrying pathogens on their feet, wings or bodies to food. Bites or stings by vectors can also lead to infection if vector is infected
Contaminated article
Involves objects such as dishes, bedding, needles, and syringes carrying microorganisms.
Bloodborne
Infection from microorganisms through infected blood products. Transfusions, kidney dialysis, injections, or accidental needle sticks serves as a method of transmission
Medical Asepsis
known as clean technique and used in all patient care. The goal is to reduce numbers of microorganisms and prevent transmission of microorganisms from one person to another
Surgical Asepsis
known as sterile technique aims to destroy all organisms and is used only in certain situations
Asepsis
the absence of bacteria, viruses, and other microorganisms.
Handwashing
is the single most effective means to reduce the risk of transmitting disease. Performing frequent and thorough handwashing is the only universally controllable factor in breaking the chain of infection at each element.
Long Wash
involves thorough washing of the hands, with lathering of the hands at least twice, and careful cleaning of the fingernails
(1) .At the beginning and end of each shift and after using the rest room or taking a meal break.(2) When hands are visibly soiled (3) Touched blood or body fluids with or without gloves.
Short Wash
CDC recommends routine handwashing for at least 15 seconds, with a 10-second rinse
Barriers
use of personal protective equipment (PPE). It is used to help protect healthcare workers from patient body fluids.
Gloves
most commonly used protective item and must be worn for any patient care with potential exposure to body fluids. Gloves provide a protective barrier when touch any body fluids.
Masks
help protect patients and healthcare personnel from upper respiratory infection and certain communicable diseases. Simple masks screen out larger particles. Particulate or respirator masks is specially fitted and designed to filter out very small particles
Eye Protection
Goggles, forehead shields are used if any danger that body fluids may splash or spray the healthcare worker
Aprons
A fluid resistant or protective apron is worn to protect healthcare workers clothing when body fluids might splash
Standard Precautions
used to reduce the risk of transmitting blood-borne pathogens and from moist body substances. The precautions apply to blood; all body fluids, secretions, secretions, non-intact skin, and mucous membranes. It is designed to reduce the risk of pathogen transmission from both known and unknown sources of infection.
Airborne Precautions
Used to prevent airborne transmission. Patients requiring airborne precautions are placed in a private room with special, monitored air flow requirements. Portable air-filtering machines may also be used. The door of the room is kept closed and patient must wear a mask
Droplet precautions
use to prevent droplet transmission. Patients are placed in a private room or with a similarly infected patient. Masks are worn when working within 3 ft. of the patient. The patient must wear a mask if they are transported outside the room.
Contact Precautions
Prevents spread of disease through direct or indirect contact with an infected person. A patient is placed in a private room or a room with similarly infected patients. Gown, gloves, and masks are worn if direct contact is required with the patient. If equipment must be used for multiple patients, carefully and thoroughly clean and disinfect the equipment before using it again.
