Module 2 quiz Flashcards

1
Q

In the inflammatory response what happens?

A
  1. Histamine causes blood vessels to dilate and become more permeable bringing more blood (fluid and cells) to infected area
  2. White blood cells ingest (phagocytose) invading organisms
  3. Fluid (plasma) may contain antibodies that act against invading organisms

Q

The current trend in hospital care is to shorten the hospital stay for surgical patients. What effect will this have on the incidence of nosocomial infections?

A

IT should reduce the risk of nosocomial infection. There are far less pathogenic bacteria in the home environment and they are less likely to be antibiotic resistant
