Device-Associated Infection Prevention Flashcards

Which component is part of the ABCDE bundle used to reduce ventilator days and VAP incidence?

Answer: Spontaneous Awakening and Breathing trials

The ABCDE bundle includes daily Spontaneous Awakening Trials and Spontaneous Breathing Trials to minimize sedation and ventilator time, reducing VAP risk.

Which oral care practice is recommended for mechanically ventilated patients to prevent VAP?

Answer: Chlorhexidine 0.12% oral rinse twice daily for cardiac surgery patients

Chlorhexidine 0.12% oral rinse is recommended for cardiac surgery ventilated patients to reduce oropharyngeal colonization and the risk of aspiration pneumonia.

Which vascular access device is associated with the highest risk of healthcare-associated bloodstream infection?

Answer: Central venous catheter

Central venous catheters carry the highest BSI risk due to their large lumen, access to central circulation, high-frequency manipulation, and prolonged dwell times.

What does the NHSN CAUTI definition specifically require regarding catheter presence?

Answer: An indwelling urinary catheter present for more than 2 calendar days before UTI symptom onset

NHSN CAUTI criteria require the indwelling urinary catheter to have been in place for more than 2 calendar days on the date of the infection event.

Which practice prevents intraluminal contamination of central venous catheters during access?

Answer: Scrubbing the catheter hub for at least 15 seconds before each access

Vigorous hub scrubbing for ≥15 seconds with chlorhexidine-alcohol or 70% isopropyl alcohol disrupts biofilm and reduces intraluminal contamination at each access event.

What is the current CDC recommendation regarding routine replacement of peripheral IV catheters in adults?

Answer: Replace only when clinically indicated rather than on a fixed schedule

CDC 2011 guidelines recommend replacing peripheral IV catheters only when clinically indicated, as this approach is equally safe as routine scheduled replacement and reduces unnecessary manipulation.
