Exam 1 Information Flashcards
What are infectious diseases
Pathogens that cause disease by disrupting vital body processes or stimulating the immune system to mount a defensive reaction. Symptoms may include high fever and inflammation.
Where can pathogens enter the body
Through the skin, respiratory system, digestive system, or reproductive system.
Which type of injury is at high risk for infection when it closes up.
Puncture injury
First stage of Pathogen Infection
Incubation- Not infectious
Second stage of Pathogen Infection
Prodromal- start to see signs and symptoms (Isolate Person)
Third Stage of Pathogen Infection
Acute- Highest development of disease, most at risk for spreading disease.
Fourth Stage of Pathogen Infection
Decline- start to recover and feel better, high risk for relapse.
Fifth Stage of Pathogen Infection
Recovery- recovering from pathogen, develop immunity (Permanent or temporary)
What is acquired Immunity
immunity that develops with exposure to various antigens
What are the four types of infectious diseases
Sporadic (random)
Endemic (certain area)
Epidemic (Widespread)
Pandemic (throughout the world, everywhere)
How is Hepatitis B spread
It is spread through unprotected sex, sharing needles, needlesticks or SHARPS
Will an individual always have symptoms if infected with hepatitis B
It is possible for an individual infected with HBV will exhibit no signs or symptoms and the virus may go undetected. Thus, the disease may be unknowingly transmitted to others through exposure to blood or other bodily fluids
What is the rate of infection for health care providers
8700 infected each year. 200 a year die.
What is the Human Immunodeficiency Virus (HIV)
A retrovirus that combines with a host cell.
May infect cells of the immune system, T-cells, B cells, Macrophages.
What are signs and symptoms of HIV
Fatigue, weight loss, muscle/joint pain, painful/swollen glands, night sweat, and fever.
What is Acquired Immunodeficiency syndrome (AIDS)
Most people with HIV will develop AIDS
No protection against infections
Extremely vulnerable to illnesses, opportunistic infections and cancer.
Kaposi’s Sarcoma and Non-Hodgkins Lymphoma.
What are the statistic for AIDS
2011: 1.2 million Americans have HIV infection
50,000 NEW INFECTIONS EACH YEAR
Since 1981, 600,000 people have died of AIDS
About 50% develop AIDS within 10 years of being infected with HIV
Life span about 2 years after developing AIDS
What is OSHA Occupational Safety and Health Administration
Sets standard requirements for employers to follows to ensure employee safety with regard to occupational exposure to bloodborne pathogens.
What are the employee requirements for OSHA
Any employee who has the potential for occupational exposure to blood or other potentially infectious materials (OPIM) is required to receive training according to the bloodborne pathogen standard.
What are some preventions for OSHA
- Engineering Controls
- Work Practice Controls
- Personal Protective Equiptment
- Universal Precautions
- Body Substance Isolation
Engineering and work practice controls
Used to eliminate or minimize exposure to bloodborne pathogens.
Employer is responsible for full cost.
Must be regularly maintained or replaced if not effective.
Required to provide hand washing facilities.
All work practices must minimize or eliminate the risk of exposure.
Contaminated Needles or Sharps
Any object that can penetrate the skin (needles, scalpels, broken tubes, dental wires)
Reusable sharps must be place in a clearly labeled puncture resistant, leak proof container immediately after use until they can be reprocessed
What are Universal Precautions
Aggressive standardized approach to infection control
Treat all human blood and certain body fluids as if they contain bloodborne pathogens.
What are materials that require universal precautions
blood, semen, vaginal secretions, cerebrospinal fluid, synovial fluid, pleural fluid, any body fluid with visible blood, any unidentifiable body fluid, saliva from dental procedures.
