PICC Line Insertion & Maintenance 2

Question 1

Which vein is considered the FIRST-CHOICE insertion site for PICC placement in adult patients?

Accepted Answer

Basilic vein

Answer

The basilic vein is preferred because it is larger, straighter, and has fewer valves than the cephalic vein, facilitating easier catheter advancement.

Question 2

When using ultrasound guidance for PICC insertion, the needle entry angle should typically be:

Accepted Answer

30–45 degrees

Answer

A 30–45 degree angle optimizes needle visualization under ultrasound while achieving adequate vein penetration depth.

Question 3

After successful PICC placement, the ideal catheter tip position is:

Accepted Answer

Superior vena cava–right atrial junction

Answer

Placement at the cavoatrial junction (lower third of the SVC) allows high blood flow to dilute infusates and reduces thrombosis risk.

Question 4

A PICC dressing should be changed every 7 days when using a chlorhexidine-impregnated sponge dressing AND whenever the dressing is:

Accepted Answer

Damp, loosened, or visibly soiled

Answer

INS standards require immediate dressing change if integrity is compromised, regardless of scheduled interval.

Question 5

Which flushing technique is recommended to prevent PICC occlusion?

Accepted Answer

Pulsatile (push-pause) flush followed by positive-pressure cap closure

Answer

The pulsatile technique creates turbulence that removes fibrin and drug residue from catheter walls better than a steady flush.
