Loading flashcards...
1

the opening where an infectious agent enters the host's body such as mucous membranes, open wounds or tubes inserted in body cavities like urinary catheters or feeding tubes

Portal of Entry

2

should always be worn if there is a risk of exposure to bodily fluids such as urine, blood, cysts, pus, etc.

Gloves

3

sexually transmitted illnesses (STI's)

Contact

4

the place where the microorganism resides, thrives and reproduces (food, water, toilet seat, elevator buttons, etc.)

Reservoir

5

human immunodeficiency virus (HIV)

Blood Borne Transmission

6

a hard-plastic container that is used to safely dispose of needles and other sharp objects; always log removal in a facility log book

Sharps Container

7

process of destroying pathogens on surfaces

Disinfection

8

set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin and mucous membranes (treat everyone as if they are infected)

Standard Precautions

9

sterile; eliminates all organisms, both pathogenic and non-pathogenic, including spores

Surgical Asepsis

10

can be used in lieu of washing with soap and water if hands are not visibly soiled

Alcohol Based Rub

11

any microorganism that can cause a disease

Infection Agent (disease)

12

a person who is at risk for developing an infection from the disease

Susceptible Host (disease in new host)

13

-all items must be thoroughly cleaned to be processed and placed in open positions -different types of metal cannot be processed together -carbon steel must be wrapped in special towels to prevent oxidation that can occur if contact is made with stainless-steel autoclave trays -sterilization indicator must be used to ensure sterility is achieved

Autoclaving

14

the place where the organism leaves the reservoir, such as the respiratory tract (nose, mouth), intestinal tract (rectum), urinary tract or blood and other bodily fluids

Portal of Exit

15

destruction of all pathogens and their spores

Sterilization

16

use 70% solution to clean a patient's skin for skin preparation

Alcohol

17

the neutralization or removal of dangerous substances or germs from an area, object or person; should be done in exam room after each patient visit -a 1:10 solution of bleach and water should be used to clean up urine or blood that has been spilled on the floor

Decontamination

18

the means by which an organism transfers from one carrier to another

Mode of Transmission

19

a way of gathering the information needed to interrupt or prevent an epidemic; each of the links in the chain must be favorable to the organism for the epidemic to continue; breaking any link can disrupt the epidemic Six Links -Infectious Agent (disease) -Reservoir -Portal of Exit -Mode of Transmission -Portal of Entry -Susceptible Host (disease in new host)

Chain of Infection

20

influenza, measles, tuberculosis

Airborne Transmission

21

clean; reduces or inhibits number and growth of microorganisms

Medical Asepsis

22

reduces the number of microbes (make something extremely clean)

Sanitization

23

-immune system -skin -mucous membranes -tears -stomach acids

Body's Natural Barriers

24

the absence of bacteria, viruses and other microorganisms

Asepsis
