while the client is receiving care in a health-care setting
-formally called nosocomial infections
-can come from exogenous source or endogenous source
-most common setting for HAIs is the ICU
-best way to prevent HAIs is through frequent and effective hand
hygiene
-most common site of HAIs is the urinary tract
-most common causative agents are Escherichia coli, Staphylococcus

-an iatrogenic infection results from a diagnostic or therapeutic
procedure
