Asepsis and Infection Control

Question 0

Answer 0

microorganisms that at capable of causing disease

Question 1

nosocomial infections

Answer 1

an infection acquired after admission to a health care facility
most common serious complication of hospitalization

Question 2

communicable (contagious)

Answer 2

an infection that can be transmitted from one person to another

Question 3

immunocompromised

Answer 3

patients who have an impaired immune system

Question 4

chain of infection

Answer 4

requires: infectious agent, reservoir, exit route, method of transmission, entrance, and host

Question 5

infectious agent

Answer 5

bacteria, viruses, fungi, protazoa

Question 6

characteristics of infectious agent

Answer 6

sufficient number of organisms
viability/virulence
invasiveness
host susceptibility 
resistance

Question 7

carrier

Answer 7

an animal or person who show no symptoms of illness but who have pathogens on or in their bodies that can be transferred

Question 8

direct contact

Answer 8

actual physical contact between source and susceptible host

Question 9

indirect contact

Answer 9

contact with contaminated indirect object, like linen, equipment, dressings

Question 10

droplet transmission

Answer 10

large particles from the respiratory system of an infected source propelled up to 1m through the air and deposited onto a susceptible host

Question 11

airborne transmission

Answer 11

organisms contained within droplet nuclei or dust particles
suspended in air for extended periods
air currents transmit these particles long distances and susceptible host inhales them

Question 12

vehicle transmission

Answer 12

a single contaminated source, like water, drugs, food, equipment, transmits infection to multiple hosts

Question 13

vectorborne

Answer 13

insects or pests transmit microbes to humans

sanguineous fluid
sero-sanguineous fluid
purulent fluid

Answer 14

serous: watery
sanguineous: bloody
sero-sanguineous: both watery and bloody
purulent: thick/puss

Question 15

exogenous infection

Answer 15

arise from microorganisms external to the individual that do not exist as normal flora

Question 16

endogenous infection

Answer 16

occurs when some of the patients flora become altered and overgrown results

Question 17

normal flora

Answer 17

mixture of bacteria normally found at specific body sites

Question 18

medical asepsis

Answer 18

clean technique

involves procedures and practices that reduce the number and prevent transfer of pathogens

Question 19

surgical asepsis

Answer 19

sterile technique

includes practices used to render and keep objects and areas free from microorganisms and spores
