Question 2

Which HAI type is most commonly associated with the use of central venous catheters?

Accepted Answer

CLABSI

Answer

Central line-associated bloodstream infections (CLABSIs) are directly linked to the presence of central venous catheters.

Question 3

Which pathogen is the most common cause of catheter-associated urinary tract infections (CAUTIs) in US hospitals?

Accepted Answer

Escherichia coli

Answer

Escherichia coli is the most frequently identified pathogen in CAUTIs, reflecting its prevalence in the gastrointestinal and perineal flora.

Question 4

The bundle approach to preventing CLABSI includes which of the following elements?

Accepted Answer

Maximal sterile barrier precautions during insertion

Answer

Maximal sterile barrier precautions (cap, mask, sterile gown, gloves, and full-body drape) during insertion is a core CLABSI prevention bundle element.

Question 5

Which measure is most effective in reducing the incidence of surgical site infections (SSIs)?
