Infection Flashcards
What are some factors that increase host susceptibility ?
- age
- underlying disease
- malignancy
- transplants
- certain medications
- surgical procedures
- radiation therapy
- indwelling devices
What is a localized infection ?
in a specific place in the body
What is systemic infection ?
spread all over the body
What are some manifestations of localized infection ?
- swelling
- redness
- heat
- pain or tenderness
- loss of function in affected body part (due to pain and inflammation)
What are some manifestations of systemic infection ?
- fever
- leukocytosis
- malaise
- anorexia
- nausea
- vomiting
- lymph node enlargement
- organ failure (when infection is left alone for so long)`
What does the incubation stage mean ?
pt. may not feel ill or have any visual manifestations
- may be detectable through labs or diagnostic tests
- bacteria has entered the body but we feel okay
What does the prodromal stage mean ?
initial manifestations
- will start to have symptoms
- fever, aches, poor appetite, malaise, runny nose
What does the acute illness stage mean ?
infection process becomes obvious
- infection considered severe
- symptoms are at it’s worst
What does period of decline stage mean ?
manifestation begin to subside
- number of infectious agents in the body decline
What is the period of convalescence stage mean ?
pt returns to previous state of health
- getting back to baseline but may be left with lasting/lingering effects
What are the stages of infection ?
- incubation
- prodromal
- acute illness
- period of decline
- period of convalescence
What are some common health care associated infections ?
- urinary tract (CAUTI)
- surgical sites (SSI)
- respiratory tract (VAP)
- blood stream (CLABSI)
What are infection bundles ?
groups of interventions we use to prevent infections with specific procedures/machines
- to improve patient outcomes
What are some risk factors for health care associated infections ?
- increased length of stay
- invasive procedures
- multi-drug resistant organismzs
- # of providers
- decreased immunity
What is asepsis ?
absence of pathogenic (disease-producing) microorganisms
What is aseptic technique ?
practices/procedures that help reduce the risk for infection
What is medical asepsis (clean technique) ?
procedures for reducing the number of organisms present and preventing the transfer of organisms
- used all the time unless you need surgical asepsis
- Ex.) hand hygiene, wiping down surfaces
