question

question
List the different links in the chain of infection and give examples for each.
answer
Infectious agent: the organism (such as Clostridium difficile) Reservoir: Patient 1 Portal of exit: bowel movement of Patient 1 Mode of transmission: nurse's hands, because this organism is not killed by alcohol-based hand gel Portal of entry: Patient 2's mouth Susceptible host: Patient 2
question
What is a health care associated infection? (HAI)
answer
an infection that is acquired while the patient is being care for in any health-care setting, including home health care and long-term health.
question
What is the single most important way to break the chain of infection and prevent HAIs?
answer
Hand Hygiene
question

answer
infection caused by one pathogen only
question

answer
caused by a second, different pathogen
question
localized infection
answer
infection is in one area of the body
question
systemic infection
answer
if infection spreads from one site to another site, such as from lungs to other organs it becomes systemic, spreading through the bloodstream
question
Of the different types of infections listed above which is the most severe and why?
answer
systemic infection, because when microorganisms are present and multiplying in the blood, it is referred to as septicemia-
question
List and understand primary defenses against infection.
answer
Skin: protects body from microbes Mucous Membrane: sticky mucus traps invading pathogens Gastrointestinal system: contains good bacteria, saliva contains enzymes to help remove microorganisms from teeth
question
List and understand secondary defenses against infection

answer
Age, chemical exposure, chronic illness, lack of exercise, lack of rest, increased stress, non-intact skin, and poor nutrition

What are the young and old at an increased risk for infection?
answer
young and infants because their immune system isn't developed and elderly because their immune system is depleted, poor hygiene and improper nutrition
question
Why does increased stress increase the risk for infection?
answer
when the body is frequently reacting to stressors, immune function can be impaired, which increases the risk of illness and infection
