VA-BC Ultrasound Guidance 2

Question 1

Which ultrasound probe orientation allows visualization of the needle tip entering the vessel lumen in real time during PICC insertion?

Accepted Answer

Longitudinal (long-axis) view

Answer

The longitudinal (long-axis) view aligns the probe parallel to the vessel, allowing continuous visualization of the entire needle shaft and tip as it enters the lumen.

Question 2

When using ultrasound to assess for a catheter tip malposition into the internal jugular vein, which finding confirms the malposition?

Accepted Answer

Catheter visible in the IJV lumen on ultrasound

Answer

Visualizing the catheter as a hyperechoic structure within the IJV lumen on ultrasound confirms malposition into that vessel.

Question 3

A vascular access nurse is scanning a patient's arm and notes a vessel that collapses completely with gentle probe pressure. This finding most likely indicates:

Accepted Answer

A patent vein

Answer

Patent veins are compressible and collapse easily under gentle probe pressure, distinguishing them from arteries and thrombosed vessels.

Question 4

What is the primary advantage of using a sterile ultrasound probe cover and gel during vascular access procedures?

Accepted Answer

Maintains a sterile field to reduce infection risk

Answer

Sterile probe covers and gel maintain the sterile field during vascular access, reducing the risk of catheter-related bloodstream infection.

Question 5

During ultrasound-guided venipuncture, the nurse observes the needle tip pushing the anterior vessel wall inward without entering the lumen. This is called:

Accepted Answer

Tenting

Answer

Tenting occurs when the needle indents the anterior vessel wall without penetrating it, often requiring slight advancement or angle adjustment to enter the lumen.
