NURS 175 LATEST REAL FINAL
PRACTICE EXAM QUESTIONS AND
ANSWERS 100% PASS
Asepsis - ANS The absence of bacteria, viruses and other microorganisms = used to prevent
infection
Communicable - ANS Meaning its contagious
Iatrogenic infection - ANS Nosocomial infection that results from a diagnostic or therapeutic
treatment.
Nosocmial infection - ANS Infection acquired by the hospital
Resident Flora - ANS Microorganisms that are always present on or in a person and usually do
not cause any disease.
Transient flora - ANS microbes that reside on the skin surface and are easily removed
Medical asepsis - ANS Known as the "clean technique" - used to keep area as clean as
possible to reduce transmission
Surgical asepsis - ANS Known as the "sterile technique" - used when you want zero
transmission of microorganisms, so everything is kept in a sterile field.

,Goal of asepsis? - ANS Elimination of infection
The 4 Principles of Asepsis ? - ANS 1. All articles used in a surgical operation have been
sterilized previously.
2. If in doubt about the sterility of anything, consider it unsterile.
3. The edge of anything that encloses sterile contents is not considered sterile. Ex rims of sterile
bottles
4. Moisture may cause contamination.
What is routine practice? - ANS Also known as universal practice or standard precautions,
these are just routine practices are used to minimize the spread of infection between people.
What is the chain of infection? - ANS 1. An infectious agent or pathogen
2. A reservoir or source for pathogen growth
3. A portal of exit from the reservoir
4. A mode of transmission
5. A portal of entry to the host
6. A susceptible host
Explain the 1st step of the chain of infection - ANS Infectious agents
-The microorganisms capable of causing infection
-Through effective hand washing many of these can be removed
Explain the 2nd step of the chain of infection - ANS Reservoir
-Where the organism is housed while it's waiting for an opportunity to infect/ multiply
Explain the 3rd step of the chain of infection - ANS Portal of Exit
2 @COPYRIGHT 2025/2026 ALLRIGHTS RESERVED.
, -The most common portals of exit include the mucous membranes (i.e., mouth, nose, vagina,
rectum) or breaks in the skin (e.g., wounds).
-Blood and body fluids are considered portals of exit and can carry microorganisms as well.
Explain the 4th step of the chain of infection - ANS Mode of Transmission
-Contact transmission
-Droplet transmission
-Airborne transmission
-Common vehicle transmission
(Ex. E.Coli outbreak on lettuce across Canada)
-Vector borne transmission
(Ex.Carriers like mosquitos or mice who carry disease)
Explain the 5th step of the chain of infection - ANS Portal of Entrance
-Once exited, transmitted, the infection now needs a place to land
-The same areas of portal exit are portal entrances
Explain the 6th step of the chain of infection - ANS Susceptible host
-Susceptibility depends on various factors, such as the virulence of the microorganisms or the
resistance or immunity that the host might have.
What is the body's response to contact with disease-causing microorganisms? -
ANS Inflammation is the body's response to contact with disease-causing microorganisms.
-Inflammation is commonly divided into two basic categories: acute or chronic.
