CRNI Vascular Access Device Management 2

Question 1

What is the recommended method for securing a peripheral IV catheter to prevent dislodgement?

Accepted Answer

Manufactured catheter stabilization device (engineered stabilization device)

Answer

Standard adhesive tape in a chevron pattern

Answer

Sutures at the insertion site

Answer

Elastic bandage wrapped around the extremity

Question 2

When performing PICC tip confirmation, what landmark indicates proper placement on a chest X-ray?

Accepted Answer

Lower third of the SVC at or near the caval-atrial junction

Answer

Above the clavicle in the subclavian vein

Answer

In the right atrium

Answer

At the level of the aortic arch

Question 3

What is the correct procedure for accessing an implanted port?

Accepted Answer

Palpate the port, cleanse with CHG, access with a non-coring (Huber) needle using sterile technique

Answer

Use any available gauge needle through the skin over the port

Answer

Access can be performed without skin antisepsis if the port was recently flushed

Answer

Use a standard hypodermic needle to access the port membrane

Question 4

How should the CRNI manage a central venous catheter with a suspected partial occlusion?

Accepted Answer

Use a gentle push-pull technique with a 10 mL syringe; if unsuccessful, instill alteplase per protocol

Answer

Forcefully flush with a 3 mL syringe to clear the occlusion

Answer

Remove the catheter and insert a new one

Answer

Increase the infusion rate to push through the occlusion

Question 5

What is the rationale for using ultrasound guidance during PICC insertion?

Accepted Answer

It improves vein visualization, increases first-attempt success, reduces complications, and aids in vein-to-catheter ratio assessment

Answer

It is required by law for all PICC insertions

Answer

It is only helpful for obese patients

Answer

It replaces the need for chest X-ray tip confirmation

Question 6

What is the CRNI's responsibility regarding midline catheter tip position?

Accepted Answer

Midline catheter tips must remain in the peripheral vasculature, with the tip at or below the axillary vein level

Answer

Midline catheter tips should be in the SVC like PICCs

Answer

Midline catheters do not require tip verification

Answer

Midline catheter tips should be in the subclavian vein
