Chapter 3 Before giving Care How infections occur? Pathogen – germ gets into the body Pathogens enter the body, over power the body’s natural defense systems and cause an illness called an infection. Most infectious diseases are caused by bacteria and viruses. (Tetanus) Bacteria are everywhere; most do not infect humans but those that do cause serious illness. How infections occur? Diseases caused by bacteria – tetanus and meningitis Body’s ability to fight infection depends on its immune system Antibiotics are prescribed that kill the bacteria or weaken them so the body can get rid of it. Viruses can cause many diseases; may be difficult to eliminate because very few medications are effective against viral infections Bloodborne Pathogens are spread For any disease to be spread; 1. 2. 3. 4. 4 conditions must be met: A pathogen is present. There is enough of the pathogen present to cause disease. Pathogen passes through the correct entry site. A person is susceptible to the pathogen. Bloodborne Pathogens are spread Hepatitis B, Hepatitis C virus, and HIV can be spread from person to person by contact transmission – infected blood or body fluids from one person enter another’s body at a correct entry site (eyes, directly touching infected blood) Indirect contact transmission- touch an object that contains blood or another body fluid of an infected person, and it enters the body through a correct entry site (soiled dressings, work or equipment surfaces) Direct Standard Precautions Personal Hygiene – wash hands Personal Protective equipment – disposable gloves, breathing barriers Clean up blood/fluids & dispose in biohazard waste container Obtaining Consent Before giving first aid to a conscious adult victim, must get their permission to give care This is called consent Victim has right to accept or refuse help Get consent by telling victim Who you are.
