What is the recommended maximum dwell time for a peripheral IV catheter in an adult patient?
Answer: 72-96 hours or based on clinical assessment
Current INS guidelines recommend replacing peripheral IV catheters every 72-96 hours or based on clinical indication, balancing infection risk with patient comfort.
Which antiseptic solution is recommended as the FIRST-LINE agent for central line dressing changes?
Answer: Chlorhexidine gluconate with alcohol
Chlorhexidine gluconate (greater than 0.5%) with alcohol is the preferred antiseptic for central line site care due to its superior and prolonged antimicrobial activity.
What is the proper technique for performing a catheter hub scrub to prevent CLABSI?
Answer: Vigorous scrubbing for at least 5-15 seconds with 70% alcohol or CHG
Hub scrubbing requires vigorous mechanical friction with an antiseptic for at least 5-15 seconds before each access to reduce intraluminal contamination.
Which bundle element is MOST effective in reducing central line-associated bloodstream infections?
Answer: Maximum sterile barrier precautions during insertion
Maximum sterile barrier precautions during CVC insertion, including cap, mask, sterile gown, sterile gloves, and large sterile drape, significantly reduces CLABSI rates.
A patient with a PICC line develops redness, swelling, and purulent drainage at the insertion site. What should the nurse suspect?
Answer: Exit site infection
Redness, swelling, and purulent drainage at the catheter insertion site are classic signs of an exit site infection requiring culture and potential catheter removal.
How frequently should transparent semipermeable membrane (TSM) dressings on central venous catheters be changed?
Answer: Every 5-7 days or when soiled, loosened, or damp
TSM dressings on CVCs should be changed every 5-7 days per INS standards, or sooner if the integrity is compromised by soiling, loosening, or moisture.
