Chapter 14 Test Or
regular handwashing, antiseptic hand washing, antiseptic hand rubs
CDC recommendations for hand hygene
plague
Caused by bacteria called Yersinia pestis
exogenous
Disease originates outside the body
endogenous
Disease originates within the body
filoviruses
Ebola and Marburg viruses are examples
Chain of Infection
Factors that must be present for disease to occur
pathogen
Germ-or disease-producing microorganism
Nonpathogens are already in your body and are beneficial, Pathogens cause infection and disease
How do nonpathogens differ from pathogens?
1.) produce poison 2.) when a pathogen in one body system enters a different body system
Identify (2) ways pathogenic organisms can cuase infection and disease
a. viruses b. rickettsiae c. protozoa d. fungi e. rickettsiae f. bacteria g. viruses h. fungi
Identify the class of microorganisms described by the following statements. a. smallest microorganisms b. parasitic microorganisms c. one-celled animal organisms found in decayed materials and contaminated water d. plantlike organisms that live on dead organic matter e. microorganisms that live on fleas, lice, ticks, and mites f. cause diseases such as gonorrhea and syphilis g. cause diseases such as measels and mumps h. cause diseases such as ringworm and athlete's foot

Identify the following shapes of bacteria. a. rod shaped: b. comma shaped: c. round or spherical arranged in a chain: d. spiral or corkscrew: e. round or spherical arranged in clusters:
anaerobic
Organisms that live and reproduce in the absence of oxygen.
aerobic
Organisms that require oxygen to live
fungi
Plantlike organisms that live on dead organic matter.
sterilization
Process that destroys all microorganisms, including spores and viruses.
disinfection
Process that destroys or kills pathogens
antiseptic
Process that inhibits or prevents the growth of pathogenic organsims
6-10 cleanings
after how many cleanings with hand rub should you wash your hands with soap and water?
filoviruses
an infectious disease that causes hemorrhagic fever
tularemia
bacteria commonly found in animals such as rats, rabbits, and insects
sterilization (ex. autoclave)
destroys all microorganisms (give ex.)
anthrax
grazing animals eat contaminated soil and become infected with this
blood and other bodily fluids
how are pathogens spread?
600,000 to 800,000
how many needlestick accidents does the CDC estimate happens each year?
anthrax
humans can contact this by eating undercooked or raw infected meat
tularemia
infectious disease caused by a bacteria called Francisella tularensis
disinfection
kills germs on surfaces
botulism
must be treated with antitoxin or paralysis spreads to the respiratory muscles and causes death
filoviruses
no effective treatment, so 50 to 90 percent of infected individuals die
antisepsis (bedodine, 70% alchohol)
prevents growth of pathogens (give ex.)
anthrax
spores of bacteria called Bacillus antracis
plague
usually transmitted by the bite of infected fleas
smallpox
vaccinations against this were no longer required after many years with no reported cases
make sure to clean, no artifical nails, real nails need to be kept short
what are some points about fingernails?
soap, warm water, friction, all surfaces, fingertips pointed downward, dry towels to turn on and off the faucet
what are some points to observe when washing your hands?
Centers for Disease Control and Prevention
what does CDC stand for?
handwashing
what is the most effective way to prevent the spread of infection?
handwashing
what is the most important method to used to practice aseptic technique?
if the hands are no visibly soiled with blood or body fluids, apply to all surfaces of the hands, rub until dry-approx 15 seconds
when can antiseptic hand rubs be used?
before invasive procedures, critical care unit, specific organisms with precautions, special circumstances control program of a health care facility
when is antiseptic hand washing used?
soap and water if hands are visibly soiled
when is regular hand washing used?
antiseptic
Absence of pathogens
a. West Nile Virus b. H5N1 c. SARS d. Monkey - Pox e. Ebola f. HIV g. hepatitis B
Identify the following viruses: a. mosquito-borne flavivirus b. virus that causes avian or bird flu c. variant of the coronavirus that can lead to respieratory failure and death d. virus affecting monekys, other primates, and rodents e. viruses that cause hemorrhagic fever f. virus that causes AIDS g. virus that affects the liver and can lead to destruction and scarring of liver cells
a. Mode of transmission b. Portal of entry c. susceptible host d. mode of transmission e. mode of transmission f. causative agent
Identify the part(s) of the chain of infection that has been eliminated by the following actions a. thorough washing of the hands b. intact unbroken skin c. healthy, well-rested individual d. cleaning and sterilizing a blood-covered instrument e. spraying to destroy mosquitoes f. rapid, accurate identification of organisms
Military, 1st responders, police, fire department, and health care personnel
If mass immunization is required for a sepcific disease, who should be vaccinated first?
nonsocomial
Infections acquired in a health care facility
handwashing, good personal hygene, use of disposable gloves, cleaning equipment and machinery
List four (4) common aseptic techniques
develop a control plan, identify all employees with exposure, provide HBV virus shot, personal protective equipment (PPE), handwashing facilities, ensure worksite is clean and sanitary, no eating, drinking, smoking, applying cosmetics, or lip balm, handling contact lenses, mouth pipetting or suctioning in any area with blood or body fluid, sharps container, post signs where there is occupational exposure, provide confidential medial evaluation for any employee that has had an exposure incident, provide training about the regulations
