2- The Well-Being of the Emergency Medical Responder Flashcards
(43 cards)
Preventing disease transmission:
1) How infections occur
2) How diseases spread from one person to another
3) What you can do to protect yourself and others
How infection occurs:
1) Pathogen gets into the body
2) Sometimes overpower body’s natural defense systems and cause illness
What causes most infectious diseases?
Bacteria and viruses
Commonly used antibiotics:
penicillin, erythromycin and tetracycline
Viruses cause:
Hepatitis, measles, mumps, chicken pox, meningitis, rubella, influenza, wartz, colds, herpes, HIV, genital warts, smallpox, Avian flu
Bacteria cause:
Tetanus, meningitis, scarlet fever, strep throat, tuberculosis, gonorrhea, syphilis, chlamydia, toxic shock syndrome, Legionnaires’ disease, diptheria, food poisoning, Lyme disease, anthrax
Rickettsia cause:
Typhus, Rocky Mountain spotted fever
Parasitic Worms cause:
Abdominal pain, anemia, lymphatic vessel blockage, lowered antibody response, respiratory and circulatory complications
Prions cause:
Creutzfeldt-Jacob disease (CJD) or bovine spongiform encephalopathy (mad cow disease)
Yeasts
Candidaisis (aka “thrush”)
The Body’s Natural Defenses:
1) Intact skin & mucous membranes (keep germs out)
2) Immune system (antibodies and white blood cells)
Mild to serious and brief =
Long lasting=
acute
chronic
Signals that the body is fighting infection
Fever, exhaustion
headache, nausea and vomiting
CRITICAL FACT
Intact skin, as well as mucous membranes in the mouth, nose and eyes, are part of the body’s natural defenses to help keep germs out.
Three different types of human immunity:
1) Inate (born with, natural barriers like skin)
2) Adaptive immunity (develops throughout our lives as we are exposed to diseases or are immunized against them)
3) Passive immunity (gained from external sources such as from a mother’s breast milk to an infant)
How diseases spread:
Exposure to blood or body fluids through injuries from needles and other sharps devises, as well as by direct and indirect contact with skin and mucous membranes.
Four conditions must be met for any disease to spread:
1) Present
2) Quantity
3) Susceptible
4) Entry site
CRITICAL FACT
For any disease to spread, pathogens must be present in sufficient quantity and pass through the broken skin or mucous membrane of a susceptible person.
Direct contact:
Occurs when infected blood or body fluid from one person enters another person’s body at a correct entry site.
Indirect contact:
Can occur when a person touches an object that contains the blood or other body fluid of an infected person; e.g. = soiled dressings or equipment
Droplet transmission
Occurs when a person inhales droplets propelled from an infected person’s cough or sneeze from a few feet and also by touching a surface recently contaminated by infected droplets then touching an entry site
Vector-borne transmission
Occurs when an infectious source, such as an animal or insect bite or sting, penetrates the body’s skin.
CRITICAL FACT
Exposure control plans, as required by OSHA, contain policies and procedures that help employers eliminate, minimize and properly report employee exposure incidents.
CRITICAL FACT
Standard precautions are safety measures to prevent occupational-risk exposure to blood or other potentially infectious materials, It assumes all body fluids may be infective.
