CRNI CRNI Peripheral Vascular Access and IV Site Management 5

Question 1

A nurse inserts a peripheral IV catheter and notes blood return, but upon flushing encounters resistance followed by swelling at the site. What does this MOST likely indicate?

Accepted Answer

Infiltration with the catheter in the subcutaneous tissue

Answer

Swelling upon flushing despite initial blood return indicates infiltration, where the catheter tip has migrated out of the vein into surrounding subcutaneous tissue.

Question 2

Which antiseptic agent and technique is recommended by INS standards for peripheral IV site preparation in adults?

Accepted Answer

2% chlorhexidine gluconate in 70% isopropyl alcohol, back-and-forth friction scrub, allowed to dry completely

Answer

INS standards recommend a >0.5% chlorhexidine with alcohol solution (typically 2% CHG in 70% IPA) applied with friction and allowed to dry completely before catheter insertion.

Question 3

A patient with a peripheral IV on continuous infusion develops a fever. The IV site appears clean without erythema or tenderness. What is the CRNI's priority assessment?

Accepted Answer

Assess for systemic signs of infection and evaluate the catheter as a potential source

Answer

Fever in a patient with a peripheral IV requires a systematic assessment to evaluate whether the catheter is a potential source of catheter-related bloodstream infection (CRBSI).

Question 4

When documenting a peripheral IV insertion per INS standards, which element is NOT required?

Accepted Answer

Patient's insurance information

Answer

IV documentation must include date/time, gauge and length, site location, number of attempts, patient tolerance, and nurse identifier — insurance information is not a clinical documentation requirement.

Question 5

A patient states they are allergic to adhesive tape. What is the MOST appropriate securement method for a peripheral IV catheter?

Accepted Answer

Use a tissue-adherent catheter securement device or silicone-based tape alternative

Answer

Engineered catheter securement devices (ECSDs) with tissue-adherent or silicone-based mechanisms provide secure catheter stabilization for patients with adhesive allergies.
