PICC Anatomy & Vascular Access Evaluation 2

Question 1

Which vein is considered the FIRST-LINE choice for PICC insertion due to its size and straight course?

Accepted Answer

Basilic vein

Answer

The basilic vein is preferred because it is the largest superficial vein of the upper arm and follows a relatively straight path toward the subclavian vein.

Question 2

The cephalic vein is less preferred for PICC placement primarily because of which anatomical feature?

Accepted Answer

It makes a sharp turn at the deltopectoral groove before joining the axillary vein

Answer

The cephalic vein takes a sharp angulation at the cephalic arch (deltopectoral groove) before joining the axillary vein, which can impede catheter advancement.

Question 3

In which anatomical position does the tip of a properly placed PICC reside?

Accepted Answer

Superior vena cava at the cavoatrial junction

Answer

Optimal PICC tip position is at the cavoatrial junction or lower third of the superior vena cava, where blood flow is high enough to dilute infusates.

Question 4

When assessing a patient's arm veins using ultrasound, which characteristic confirms the vessel is a vein rather than an artery?

Accepted Answer

Thin walls that collapse easily with gentle probe pressure

Answer

Veins have thin, compliant walls and collapse readily under gentle ultrasound probe compression, distinguishing them from arteries.

Question 5

The axillary vein becomes the subclavian vein at which anatomical landmark?

Accepted Answer

The lateral border of the first rib

Answer

The axillary vein transitions into the subclavian vein at the lateral border of the first rib.
