Question | Answer |
---|---|
What does mode of transmission mean? | How microorganisms travel between hosts. |
Describe direct contact. | Person to person. |
Describe indirect contact. | Person to object to person. |
Describe droplet transmission. | Coughs or sneezes. |
Describe vehicle route. | Transmission via food, water, body fluids. |
Describe airborne transmission. | Dust, evaporated droplets in the air, particles of hair and skin, ventilation systems. |
Describe vector transmission. | Bird, animal or insect. ie. West Nile Virus |
Describe normal flora. | Natural to the body, do not cause disease. |
Describe bacteria. | Single-celled organisms that multiply by cell division, some cause infection, non-pathogenic. |
Describe viruses | Cannot live on their own, need a host cell to multiply, very small organism, not seen by regular microscope. |
Describe fungi | Single-celled, uses spores to reproduce. |
Describe protozoa | Single-celled, found mostly in contaminated water and sewage systems. ie. Beaver Fever |
How should you treat someone with HIV/AIDS? | Respect, empathy, acceptance, dignity, warmth. |
What are the standard precautions? | PPE-gloves, gowns, apron, masks, protective eyewear. Protection from cross contamination. |
What are the contraindications of MMR? | Sensitivity, immunoglobulin, pregnancy. |
What is a pathogen? | Microorganisms causing disease. |
What is chemical disinfection used for? | Used for heat sensitive equipment. |
What is medical asepsis? | Killing germs after they leave the body. |
What is surgical asepsis? | Sterilization-destroy all pathogens before they enter the body. |
What is the most effective method of preventing the spread of infectious organisms? | Hand washing. |
Why do vaccines work? | The body responds in the same manner, whether exposed naturally or via a vaccine. Builds up an immunity. |
What does the chain of infection mean? | If one of the links in the chain of infection breaks, it cannot continue. |
How can AIDS be transmitted? | Unprotected sexual intercourse, shared needles or other drug equipment, injury from a needle or sharp with contaminated blood. ie. Tattooing, acupuncture, body piercings. |
What is the "universal disinfectant"? | Bleach. |
What is postexposure prophylaxis? | Immediate and preventative treatment to prevent infection after exposure to a dangerous virus. |
autoclave | A device using steam for sterilization. |
antigen | A pathogen or any other substance that induces an antibody response. |
antibody | A protein specific to a certain antigen that weakens or destroys pathogens. |
nosocomial infection | A hospital-related infection; one that is not present or incubating when a patient is admitted to a hospital or healthcare facility. |
systemic infection | An infection that has spread to more than one region of the body. |
sharp | Any instrument with a sharp edge or point, such as a scalpel, scissors or a needle. |
topical | Applied to the skin or affected area. |
anaerobic bacteria | Bacteria that do not require oxygen to grow. |
aerobic bacteria | Bacteria that require oxygen to grow. |
teratogenic | Causing abnormalities in the fetus. |
antiseptic | A cleaning agent applied to living tissue to destroy pathogens. |
latent infection | One in which the symptoms disappear and recur, while the disease-causing agent remains in the body. |
sterile | Completely free of pathogens. |
sterilant | A substance that destroys or eliminates all forms of microbial life in an inanimate environment. |
disinfectant | A chemical substance that destroys or eliminates specific species of infectious microorganisms. It is not usually effective against bacterial spores. |
infection | A disease process that results from the entry and spread of a microorganism. |
contagious/communicable disease | A disease that is spread from person to person. |
immunity | An individual's ability to fight off disease. |
active infection | An infection in which signs and symptoms are present. |
otitis media | An infection of the middle ear. |
acute infection | An infection that is time limited. |
quarantine | Isolating or separating a client, client-care unit or facility. |
bactericidal | Killing microorganisms. |
local infection | An infection that is confined to a specific region of the body. |
sanitization | Removal of gross contaminations and some microorganisms from instruments, skin, and so on, the lowest level of medical hygiene. |
sterile techniques | Methods to avoid contamination of sterile materials. |
pathogen | A microorganism that causes disease. |
disinfection | A more thorough removal of contaminants than sanitization but less thorough than sterilization. |
nonpathogenic | Non causing disease. |
opportunistic infection | An infection that does not ordinarily cause disease but does so under certain circumstances, for example, in compromised immune systems; so called because it takes advantage of an ""opportunity". |
microorganism | An organism so small that it can only be seen under a microscope. |
remission | A period in which a chronic infection shoes no symptoms. |
exacurbation | A period in which a chronic infection shows symptoms. |
chronic infection | One that is persistent over a long period of time, perhaps life. |
sanitizer | A substance that significantly reduces the bacterial population in an inanimate environment but does not destroy all bacteria or other microorganisms. |
bacteriostatic | Reducing or inhibiting the number of microorganisms. |
relapse | The re-emergence of an initial infection after it appears to have subsided but has not been cured. |
recurrent infection | A distinct episode of an infection after recovery from the initial infection; may involve the same pathogens or different ones. |
immunoglobulin | A serum that contains antibodies that can help protect an exposed person from contracting the disease. |
asepsis | A state in which pathogens are absent or reduced. There are two principal types of asepsis: medical and surgical. |
sterilization | The process of destroying all microorganisms, including bacterial endospores and viruses. The highest level of cleanliness. |
virulence | The power of a microbe to produce a disease in a particular host. |
contamination | The presence of pathogens on an object. |
post exposure prophylasis | Treatment after exposure to a pathogen. |
asymptomatic | Without clinical signs or symptoms. |
