Immunity results when natural antibodies are passed from one body to another,
such as from mother to baby through the placenta or through breastfeeding -
ANSWER natural passive immunity
After a person acquires an infection, the body produces its own antibodies to fight
the disease-causing organism and protect from infection by this organism in the
future - ANSWER natural active immunity
This type of immunity offers long-lasting or even lifetime protection after the
administration of a weakened or dead vaccine - ANSWER artificial active
immunity
Protection from infection is achieved when a person receives serum from another
person or animal that has already produced antibodies against the pathogen -
ANSWER artificial passive immunity
Helper T cells play a supportive role in cell-mediated responses by secreting
_____________, which attracts infection-fighting white blood cells - ANSWER
interleukin
T/F Patients with poor peripheral circulation often have skin discoloration, rather
than signs of inflammation, when experiencing an infection - ANSWER true
,Normal WBC count - ANSWER 5,000-10,000/mm3
For most diseases, at least ____% of the population must be immunized in order
to protect the entire population from the disease - ANSWER 85
removes pathogens on inanimate objects by physical or chemical means, including
steam, gas, chemicals, and ultraviolet light - ANSWER disinfection
refers to procedures that decrease the potential for the spread of infections -
ANSWER medical asepsis
explain the difference between semi-critical and noncritical items for disinfection -
ANSWER Semicritical items are those that contact mucous membranes or
nonintact skin. They must be free of all microorganisms except bacterial spores, so
they must at least be disinfected and sometimes sterilized (anesthesia equipment
or endoscopes)
Noncritical items are supplies and equipment that come in contact with intact skin
but not mucous membranes. They do not carry a high risk of infection
transmission, and they can be decontaminated where they are used (bp cuffs,
stethoscopes, floors)
the elimination of all microorganisms (except prions) in or on an object -
ANSWER sterilization
,Critical items are those that pose a high risk for infection if they are contaminated
with any microorganism: - ANSWER IV's, catheters, chest tubes, lab needles,
surgical equipment, wound dressing
What Role Does the Infection Preventionist Nurse Play? - ANSWER The task of
the infection prevention nurse is to minimize the number of infections in the
healthcare facility.
The infection prevention nurse also functions as an epidemiologist, tracking down
the source of HAIs and strengthening measures to prevent their recurrence.
T/F Alcohol-based solutions are not effective against spores - ANSWER true
name two microorganisms that requires handwashing instead of using an alcohol
based rub - ANSWER c. diff and bacillus anthracis
kinesthetic sense - ANSWER the sense of body position and movement of
body parts relative to each other
This is why the incidence of choking is highest between ____ months and ____
years of age - ANSWER 6;3
Infants and toddlers are curious and tend to explore the environment by putting
objects in their mouth
the leading cause of death for children aged 1 to 4, followed by motor vehicle
accidents - ANSWER drowning
, bone and muscle injuries are common. Injuries are often related to sports,
skateboarding, bicycle riding, and playground injuries - ANSWER school age
children
T/F Unintentional poisoning causes more deaths than do motor vehicle accidents
in adolescents - ANSWER true
For most poisonings, the most effective intervention is professional administration
of activated ___________ orally or via gastric tube - ANSWER charcoal
the most common cause of burns in children younger than age 3
this type of burn in a child should prompt you to assess for abuse - ANSWER
scalding burns
leading cause of fatal home fires - ANSWER smoking
the leading cause of death for infants younger than 1 year - ANSWER
suffocation by smothering
padded cribs, excess pillows, pacifier strings, toys
typically a finding related not to individual error but to a process or system that
has a potential for redesign to reduce risk
