NURS411 Infection Ppt Exam
Study
nature of infection: infection/colonization/communicable disease - Answer -Infection:
the invasion of a susceptible host by pathogens or microorganisms; results in disease.
-Colonization: presence and growth of microorganisms within a host without tissue
invasion or damage.
-Communicable disease: the infectious process transmitted from one person to another.
mode of transmission - Answer •Infectious agent or pathogen
•Reservoir or source for pathogen growth: humans/animals
•Portal of exit: pathway for pathogen to leave reservoir (blood/respiratory tract)
•Mode of transmission: how it spreads (airborne/direct contact)
•Portal of entry: how pathogen enters host (mucous membrane/broken skin)
•Susceptible host- individual at risk due to weakened defense
4 stages - Answer -Incubation period: no symptoms
-Prodromal stage: non disease specific symptoms
-Illness stage: symptoms clear for disease
-Convalescence: recovering but still sick
- Answer •Normal flora
-Microorganisms
-Maintain a sensitive balance with other microorganisms to prevent infection. Any factor
that disrupts this balance places a person at increased risk for acquiring a disease.
•Body system defenses
inflammation: body response to injury blood flow increase and WBC action
immune response: send immune cells to fight off infection
- organs
defenses against infection - inflammation - Answer •Inflammation
-Signs of local inflammation and infection are identical.
