How are Catheter Associated Bloodstream Infections classified?
The presence of biofilms on the catheter
The presence of actively dividing bacteria in the blood

The most common cause of Catheter Ass. Blood. Infections is Coagulase -ve Staph.
How do the bacteria usually enter the blood?
From biofilms on equipment
I couldn't think of anything else

Metastasis
Developing drug resistance
Which of the following (along with those from Cath. Ass. Blood. Inf.) is a precaution in Cath. Ass. UTIs?
