A peripheral IV dressing is found to be damp and partially lifted. What is the correct nursing action?
Answer: Change the dressing immediately using aseptic technique
A compromised dressing breaks the sterile barrier and must be replaced immediately using aseptic technique to prevent infection.
Which antiseptic is recommended by INS for peripheral IV insertion site skin preparation?
Answer: >0.5% chlorhexidine gluconate in 70% isopropyl alcohol
Chlorhexidine gluconate (>0.5%) in 70% isopropyl alcohol is the INS-preferred antiseptic because it provides residual antimicrobial activity.
After phlebitis develops at a peripheral IV site, where should the replacement IV be inserted?
Answer: In the opposite extremity or proximal to the inflamed site
Restarting distal to an inflamed vein risks re-exposing the new catheter to the same damaged vessel; the opposite arm or a proximal site is preferred.
What is the INS-recommended flush volume for a peripheral IV catheter before and after medication administration?
Answer: At least 10 mL of preservative-free normal saline
At least 10 mL of preservative-free normal saline before and after medication ensures catheter patency and prevents drug incompatibilities.
The pulsatile (push-pause) flushing technique is used primarily to:
Answer: Create turbulence that dislodges fibrin and drug deposits from the catheter lumen
The push-pause motion generates turbulent flow inside the catheter, effectively clearing fibrin and drug residue that could cause occlusion.
Positive-pressure technique when disconnecting IV tubing is used to prevent which complication?
Answer: Blood reflux into the catheter lumen causing clot formation
Positive-pressure flushing prevents blood from flowing back into the catheter lumen upon syringe disconnection, which would lead to clot formation and occlusion.
