Question | Answer |
---|---|
vaccines | pharmacologic agent capable of producing artificial active immunity.` |
virulence | an organism relative power and degree of pathogenicity. |
severe acute respiratory syndrome ( SARS) | a viral outbreak of a respiratory illness first reported in Asia in 2003; spread by close person-to-person contact and characterized by fever and respiratoy symptoms. |
mortality | number of cases of deaths to a given population. |
morbidity | number of cases of disease in a specific population. |
transmission | spread of infectious disease by direct contact, indirect contact, inhalation, or bloodborne contact. |
infectious agents | pathogen responsible for a specific infectious disease. |
epidemiology | is the science that studies the history, cause, and patterns of infectious diseases. |
infection control | methods to eliminate or redice the transmission of infectious microorganisms. |
bloodborne pathogen | microorganism capable of causing disease found in blood or components of blood. |
immunosuppresed | referring to a pt. because immune sys is unhealthy because of disease,medication, gentics,ect..also antibodies produced by the cell of the immune system. |
microorganisms | microscopic living creature capable of transmisson and reproduction in specific circumstances. are found almost every where and cannot be seen by the naked eye. |
pathogens | microorganisms that can cause infectious disease. |
Chain of Infection | 1. infectious agent2. reservior3. portal of exit4. means of transmission5. portal of entry6. susceptible host |
infectious agents | virus, bacteria, fungi, parasites, and rickettsia |
Virus | virus are pathogens that require a living cell for reproduction. |
palliative | measures taken to relieve symptoms of disease. |
Bacteria | are single-celled microorganisms that live in tissue rather than in body cels and are identified by characteristics shapes or morphology (form and structure of an organism) |
fungi | are microoangism that may be unicelluar (single-celled) |
parasites | organisms that live in or another orgamism are classified as parasites. |
Riskettsia | are intracelluar parasites smiliar to a virus, they are larger than virsus and can be seen undre conventional microscope. |
excretions | waste matter the elimination of waste products from the body |
secretions | substance produced by the cells of glandular organs from material in the blood |
standard Precautions | dev in 1996 by the CDC they privide a wider range of protection and are used any time there is contact w/blood,moistbody fluid, mucous membranes, or nonintact skin ther are designed to protect all health care provider,pts, and visitors |
Transmission Based Precautions | seconf tier of CDC guide lines applies to specific catagories of pts that include air, contact and droplet precautions |
Means of Transmission | 1. direct contact 3. Bloodborne Transmission 4. ingestion5. inderect contact 6. Vector (a carrier of disease) |
Portal of Entry | broken skin mucous membrane and systems of the body exposed to external envirorment breathing in airborne microoganisms allows infectious disease to enter the lungs. |
growth requirements for microorganisms | oxygen, lack of or no oxygen, moisture nutrition, temperature,darkness |
Riskerrsiae | ticks, lime, fleas, and mites |
Reservior | second link in chain infection; people, equipment, supplies, water, food animals, insects |
Portal of entry | fith link in chain infection; broken or non-intact skin, respiratory tract, gastrointestinal tract, mucous membranes, reproductive system |
Susceptible Host | sixth link in chain of infection; number and specific type of pathogen, duration of exposre, general physical health, psychological health status, occupation or lifestyle envirorment, underlying diseases or condtitions, youth or advanced age |
Bodys Natural Barriers | physical,chemical,cellular |
Inflammatory Response | cardinal signs are redness, heat, swelling and pain; dilation of vessels increase blood flow, plasma moves into tissue, white blood cells activated to fight infection, phagocytes destroy pathogens |
pathogen | disease producing microorganism |
Immune-system response | recognition of invader,growth of defense, attack against infection, slowdonw of immune response following the death of infectious agent |
immunity | *naturally acquired active immunity* artificially acquired active immunity* congenital acquired active immunity* artificially acquired passaive immunity |
purulent | forming or containing puse |
barriers | to protect an individual form contact wirh blood and other potenitally infected materials. like PPE |
PPE | personal protective equipement |
immune system | purpose is to protect against pathogens and abnormal cell growth |
Cell-mediated immunity | usually involved in attacks and eliminates pathogens |
humoral immunity | produces antibodies that are capable of killing miccrorganisms and of reconigzing the pathogen in the future. |
AIDS | is caused by a blood born virus, HIVthe viral infection directly affects the immune response |
HIV | is responsible for the T cell destruction, t cells are white blood cells that provide immunity |
hepatitis A | HAV- MOST COMMON VIRUS |
hepatitis B | HBV-MOST COMMON VIRUS concered a serious biohazard for health care providers, it is easier to contract, symptoms are loss of appettite, fatigue, nausea, headahce, fever, and juandice this is a chroni disease, |
HEPATITITS C | HCV-MOST COMMON VIRUS, can become chronic individuals can carry the virus in their blood for the rest of their lives, damages the liver and causes cirrhoisia and liver failure, |
HEPATITIS D | HDV-LESS COMMON VIRUS |
HEPATITIS E | HEV-LESS COMMON VIRUS |
medical asepsis | is the use of practices such as hand washing general cleaning and disinfecting of contaiminated surfaces |
surgical aspsis | is to prevent organisms from entering the pts body during an invasive procedure |
