NUR 101 – Remediation Assignment for those scoring less than 80% on Exam 3. This is to
prepare you for Exam 4.
Answers must be complete sentences unless otherwise indicated.
SECTION 1
1. Chain of Infection
Describe each link and provide one clinical example:
• Infectious agent: _An infectious agent is something that contains
bacteria, fungi, virus, parasite, or prion.__
Example: __A clinical example of an infectious agent would be
touching bedding with drainage from a patient's wound, not washing
our hands and then touching another patient.___
• Reservoir: _A reservoir is the habitat of the infectious agent and is
where it lives, grows, and reproduces itself or replicates.___
Example: __An clinical example of a reservoir would be a person with
a common cold._
• Portal of exit: _A portal of exit is the route by which an infectious
pathogen can leave the reservoir._
Example: _A clinical example of a portal of exit would be a patient
coughing; the cough is spreading pathogens through the respiratory
tract._
• Mode of transmission: _How an infectious agent travels to other
places and peoples because they cannot travel on their own. __
Example: __A clinical example of a mode of transmission would be if
an infected person coughs or sneezes on or near you.Tthe respiratory
droplets could enter into the nose or land on unwashed hands and
spread the illness._
• Portal of entry: _The portal of entry provides a place for an infectious
agent to enter the individual so it can replicate or its toxin can
act._____
Example: _A clinical example of a portal of entry would be a patient
with a broken leg sharing a room with a patient with covid and the the
patient with the broken leg contracting covid. This occurs because the
patient breathed in the pathogen, making is respiratory tract the
portal of entry.__
• Susceptible host: __A susceptible host is require for the infectious
agent to take hold and become a reservoir for infection; a susceptible
host is more likely to succumb to diseases.__
Example: _A clinical example of a susceptible host would be a patient
who hasn't gotten the influenza vaccine contracting the influenza
, virus.__
2. CDC Rationale for Gloves
List all reasons gloves are worn:
• Gloves should be used whenever HCWs anticipate contact with blood,
bodily fluids, mucous membranes, nonintact skin, or potentially
contaminated surfaces and equipment. This helps prevent the spread
of illness.
• Gloves must be changed between patient contacts and when moving
from contaminated to clean tasks for the same patient. This helps
prevent microorganisms from inadvertently spreading between
patients.
• Healthcare staff should wash their hands before and after wearing
and removing gloves. This helps to prevent contamination.
• Gloves protect the wearer from contracting an illness.
• Gloves protect the patient form contracting an illness.
• Gloves reduce the spread of microorganism by creating a barrier.
3. Hand Hygiene Importance
Why is hand hygiene the most important infection control measure?
Hand hygiene is the most important step to decrease the spread of
microorganism transmission.
4. Transmission Types
Describe the mode of transmission of the following:
Direct contact: _Direct contact transmission occurs when microorganisms
are directly moved from the infected person to another person without
having a contaminated object or person between the two._
Indirect contact: _Indirect contact transmission occurs when
microorganisms are moved from the infected person to another person with
a contaminated object or person between the two.___
Droplet: _Droplet transmission occurs when airborne droplets from the
respiratory tract of a client travel through the air and into the mucosa of a
