How do healthcare workers protect themselves from
coming into contact with infectious material, sharp injuries,
and/ or exposure to a communicable disease? - Answer-
by applying knowledge of the infectious process and using
appropriate personal protective e How do healthcare
workers protect themselves from coming into contact with
infectious material, sharp injuries, and/ or exposure to a
communicable disease? - Answer-by applying knowledge
of the infectious process and using appropriate personal
protective equipment.
Diseases such as HEP B and C, HIV/AIDS, TB, and
multidrug resistant organisms require a greater emphasis
on infection prevention and control techniques.
What is a HAI (Health Care Associated Infection)? -
Answer-Infection acquired following admission to a HC
facility NOT present prior to admission
,2|Page
-Nosocomial
How do HAIs significantly increase costs of health care? -
Answer-1. Extending hospital stays
2. Increased disability
3. Increased costs of antibiotics
4. Prolonged recovery times.
HAIs costs are often not reimbursed by
Medicare/Medicaid.
WHO is susceptible to HAIs? - Answer-ALL patients
ALL health care workers
NURSES have a higher occupational exposure than other
HC professionals due to frequent patient contact!
What is an infection? - Answer-the invasion of a
susceptible host by pathogens or microorganisms
resulting in disease. * Only results if the pathogen
multiplies and alters normal tissue function.
,3|Page
It is different from a colonization in which a colonization is
the presence and growth of microorganisms within a host
but without tissue invasion or damage.
some infectious disease such as meningitis, and
pneumonia have a low or no risk for transmission.
Although it may be serious for the patient they do not pose
a risk to others including caregivers.
Communicable disease - Answer-an infectious disease
that can be transmitted from one person to another
Difference between symptomatic and asymptomatic
infections - Answer-Symptomatic infection: if the
pathogens multiply and cause clinical signs and symptoms
asymptomatic infection: if clinical signs and symptoms are
not present. Ex. HEP C can be asymptomatic, it is most
efficiently transmitted thru direct passage of blood into the
skin from a percutaneous exposure even if the source
patient is asymptomatic.
, 4|Page
The chain of infection - Answer-The presence of a
pathogen does not mean that an infection will occur.
Infection occurs in a cycle that depends on the presence
of all of the following elements:
•An infectious agent or pathogen
•A reservoir or source for pathogen growth
•A port of exit from the reservoir
•A mode of transmission
•A port of entry to a host
•A susceptible host
(Infectious agent, reservoir, portal of exit, mode of
transmission, portal of entry, host.)
* an infection can develop if this chain remains
uninterrupted. Preventing infections involves breaking the
chain of infection.
What is the infectious agent element of the chain of
infection?
