PICC Line Insertion & Maintenance 3

Question 1

Which landmark is used to estimate PICC insertion length before catheter placement?

Accepted Answer

Insertion site to the sternal notch to the third intercostal space

Answer

Measuring from the insertion site to the sternal notch and then down to the third intercostal space approximates the distance to the cavoatrial junction.

Question 2

The maximum dwell time for a PICC is determined primarily by:

Accepted Answer

Ongoing clinical need, absence of complications, and device functionality

Answer

INS guidelines state PICCs should remain in place only as long as clinically indicated; routine replacement on a fixed schedule is not recommended.

Question 3

Trimming a PICC catheter to the correct length BEFORE insertion is important because:

Accepted Answer

PICCs cannot be shortened after placement without increasing infection risk

Answer

Cutting a PICC after insertion exposes the internal lumen to contaminants and compromises catheter integrity.

Question 4

Which solution is recommended for routine PICC lumen flushing in adult patients per INS standards?

Accepted Answer

0.9% sodium chloride

Answer

Normal saline (0.9% NaCl) is the recommended flush solution for most PICC lumens; heparin is not routinely required.

Question 5

During PICC insertion using the modified Seldinger technique, after the guidewire is advanced, the next step is to:

Accepted Answer

Remove the needle while holding the guidewire in place

Answer

The needle is carefully withdrawn while maintaining guidewire position so the dilator and catheter can be threaded over the wire.
