Chapter 7 Flashcards
Asepsis ?
The increase of transmission infection,not only in health care facilities but also in home
Microorganisms?
Tiny usually microscope ,entities capable of carrying on living process ( are harmless nonpathogenic ) and most individuals don’t produce disease and pathogenic cause specific disease or infections
What is involve implementation of policies and procedures in hospitals and other health care facilities to minimize the?
spread of healthcare associated infection to patients and staff members
What techniques aid the accomplishing asepsis ?
The absence of pathogenic microorganisms divide two Medical asepsis and Surgical asepsis
Medical asepsis ?
Consists of techniques inhibit the growth and transmission of pathogenic microorganisms ( also know clean technique and is used in many daily activities, such as hand hygiene and changing of patients bed lines)
Surgical asepsis?
Consist of technical designed to destroy all microorganisms and their spores ( the reproductive cell of some microorganisms, such as fungi or protozoa )
Surgical asepsis is known as ?
Sterile technique and is used specialized areas ,such as the operating room, during invasive procedure such as urinary catheter insertion
What are the following six elements necessary for infection referred to as chain of infection?
1.infection agent ( a pathogen )
2.Reservior ( where the pathogen can grow )
- Portal of exit ( exit route ) exit route from the reservoir
4.Mode method of transmission ( method or vehicle of transportation,such as exudate ,feces,air droplet , hands , and needles
5.Portal of energy (entrance) entrance though skin , mucous lining of mouth
- Host another person or animals that is susceptible to the pathogen
What are the health care workers who have several ways to help their patients remain free of infection ?
Proper disinfection (the use of chemical that can be applied to objects to destroy microorganisms) ,
Proper use of antiseptic a substance that needs to inhibit the growth and reproduction of microorganisms may use human
Bacteria have many different characteristics. What are they ?
round example include coccus , Oblong include vibrio , Spiral ( some are shaped like commas another like square
Aerobic Bacteria Grow?
Grow only in the present of oxygen
Anaerobic Bacteria Grow?
grow only absence of oxygen no oxygen need
Motility ?
Possibly because of fine,hairlike projections, flagella that extend from bacterial cells
Locomotion?
The spirochete is achieved with a wiggling motion that involves entire cell body
Some bacteria have the ability to form capsules around?
The cell wall these mucilaginous ( of thick ,sticky,slimy substance ) envelopes form when the bacteria environment hostile capsule is defense mechanism to help protect the bacteria
The streptococcus bacteria is ?
Responsible for more disease than any other organism
Rocky Mountain Spotted fever ?
It transmitted to human through bites of an infected ticket they live on many different kinds of animals
The spore forming bacteria?
Bacillus Anthracis cause acute infection disease anthrax
What are anthrax infections that occur in three forms?
Cutaneous (skin) , Gastrointestinal, Inhalation
Anthracis spores Can live in the soil for many years. How was it transmitted?
Casual Contact from Person to person doesn’t not spread ,intentional exposure biology terrrorism event mostly like contact with skin
Anthracis (bacteria ) is considered by and its diagnosed ?
Centers for disease Control and Prevention (CDC) its diagnosed when detected blood, skin lesions,or respiratory secretions and MAke sure treatment is antibiotics such ciprofloxacin or Doxycycline approved FDA and Prevention there is vaccines
Virus?
Are the smallest known agent to causes disease they are not complete cells but are composed RNA and DNA
Where does the virus gain portals (entrance) to the body ?
Respiratory tract , gastrointestinal tract, broken skin
Without adequate medication Viruses be caused ?
Which Human immunodeficiency virus HIV reproduces , the immune system continues to be stressed to the point at which he can no longer fight off even the most common function
Fungi ?
(Mycotic) infection common disease human ,they belong plant kingdom although many are harmless responsible infection and mycotic infection caused by yeast and molds
Coccidioidomycosis (valley fever) and Histoplasmosis disease are examples of ?
systemic funga respiratory infection
Protozoa are where they are found ?
Single celled animals they exist everywhere natural are and found intestinal tract , genitourinary tract, respiratory tract , circulation systems of human and other animals
Protozoa are responsible?
Malaria, amebic dysentery , and African sleeping sickness

Carrier or Vector is?
Is a person or animals that does not become illnes but harbors and spread an organism causing disease in other
Portal of exit?
A microorganisms does not have the capacity to cause disease in another host without finding a point of escape from reservoir
