Egan's Chapter 4 - Infection Control COMPLETE (2025) EXAM TEST WITH LATEST UPDATED
(QUESTIONS AND ANSWERS) already passed!!
2 hand hygiene options and when to use - ✔✔ -hand washing with plain antiseptic-containing soap
with water for at least 15 seconds
-alcohol-based products-gels/foams
use: before and after all patients, contact with body fluids
5 major routes for transmission of pathogens - ✔✔ -contact
-droplet
-airborne
-common vehicle
vector airborne
Airborne transmission - ✔✔ -spread of airborne droplet nuclei
-small particles less than or equal to 5um
-special air handling, ventilation, and respiratory protection is needed
N-95 respirators or higher are needed to prevent transmission
Among respiratory care equipment what have the greatest potential to spread infection? - ✔✔
large-volume nebulizers. (Egan Pg 74)
antiseptics - ✔✔ tending to inhibit growth and reproduction of microorganisms
bactericidal - ✔✔ substances with the ability to kill micro-organisms
bacteriostatic - ✔✔ ability to restrain the growth of micro-organisms
cohorting - ✔✔ grouping individuals together who share a common characteristic such as age,
gender, infection
, contact precautions - ✔✔ safeguards designed to reduce the risk of transmission of
epidemiologically important microorganisms by direct of indirect contact
Direct contact transmission - ✔✔ pathogen is transferred from one person to another
disinfection - ✔✔ the process of destroying at least the vegetative phase of pathogenic
microorganisms by physical or chemical means
droplet nuclei - ✔✔ residue of evaporated water droplets; owing to their small size(0.5-12mm)
droplet nuclei can remain suspended in the air for long periods of time
droplet precautions - ✔✔ safe gaurds designed to reduce the risk of droplet transmission of
infectious agents
droplet transmission - ✔✔ -form of contact transmission
-transmission occurs when infectious droplets are propelled and deposed on another person
-usually less than 3 feet through the air
examples are: sneezes and cough
Equipment processing definitions: Cleaning - ✔✔ removal of all foreign material from objects
Equipment processing definitions: disinfection - ✔✔ inactivation of most pathogenic organisms,
excluding spores
Equipment processing definitions: high level - ✔✔ inactivation of all microorganisms EXCEPT
bacterial spores
Equipment processing definitions: Intermediate-level - ✔✔ inactivation of all vegetative bacterial
most viruses most fungi, without destruction of bacterial spores
Equipment processing definitions: sterilization - ✔✔ complete destruction of all forms of microbial
life
