tion not detected or untreated.
28. Normal Flora Microorganisms that reside normally in our body. They
help resist infection by releasing antibacterial substances
and inhibiting multiplication of pathogenic microorgan-
isms
29. Body De- Normal flora, intact skin, mucus membranes, cilli in respi-
fense Mecha- ratory system, fever, inflammation, vascular and cellular
nisms Against response, and tissue repair
Infection
30. Inflammation Vascular and cellular response leads to blood gather-
ing in the area, exudates appear (serous=clear, san-
guineous=red, purulent=white/yellow), tissue repair
31. Healthcare-Asso- Also called nosocomial infection, results from delivery of
ciated Infection health services in a health care facility. Can occur as
(HAI) the result of invasive procedures, antibiotic administra-
tion, the presence of multidrug-resistant organisms, and
breaks in infection prevention and control activities
32. Patients at Risk If the patient has multiple illnesses, older adults, poorly
for HAI nourished, lowered resistance to infection critical/chronic
