CRNI CRNI Peripheral Vascular Access and IV Site Management 4

Question 1

A patient receiving a vesicant via peripheral IV begins to complain of burning and the nurse notes swelling at the site. What is the FIRST action the nurse should take?

Accepted Answer

Aspirate any remaining drug before removing the catheter

Answer

When extravasation of a vesicant is suspected, the nurse should stop the infusion and attempt to aspirate residual drug from the catheter before removal to minimize tissue damage.

Question 2

Which gauge peripheral IV catheter is MOST appropriate for a rapid blood transfusion in an adult patient?

Accepted Answer

18 gauge

Answer

An 18-gauge catheter is preferred for blood transfusions requiring rapid infusion because its larger lumen accommodates higher flow rates without hemolysis.

Question 3

What is the maximum recommended dwell time for a peripheral IV catheter in adults according to INS standards?

Accepted Answer

No set time limit if site is without complications

Answer

INS 2021 standards recommend removing peripheral IV catheters based on clinical indication rather than a routine time-based replacement schedule, provided the site shows no signs of complications.

Question 4

A nurse is assessing a peripheral IV site and notes a PICC score of 2 (slight tenderness, no erythema). What is the appropriate intervention?

Accepted Answer

Remove the catheter and resite in the opposite extremity

Answer

A VIP (Visual Infusion Phlebitis) or phlebitis score of 2 indicates early phlebitis and warrants removal of the catheter and resiting at a new location.

Question 5

Which anatomical site is CONTRAINDICATED for peripheral IV insertion in most adult patients?

Accepted Answer

Lower extremity foot veins

Answer

Lower extremity veins are generally contraindicated for peripheral IV access in adults due to the high risk of thrombophlebitis and deep vein thrombosis.
