Device Selection & Insertion Techniques Flashcards

A patient requires 6 weeks of IV antibiotics but has poor peripheral veins. Which device is most appropriate?

Answer: PICC line

A PICC line is ideal for 6 weeks of IV therapy, providing reliable central access when peripheral veins are poor.

Which gauge needle is preferred for a rapid blood transfusion in an emergency adult patient?

Answer: 18 gauge

An 18-gauge catheter allows rapid infusion rates needed for emergency transfusions without hemolysis risk.

When inserting a PICC, the tip should be confirmed at which anatomical location?

Answer: Superior vena cava/right atrial junction

PICC tip placement at the cavoatrial junction (SVC/RA junction) is the standard for central venous catheter placement.

A midline catheter is contraindicated in which clinical scenario?

Answer: Vesicant chemotherapy administration

Vesicants must be administered through a central venous access device because extravasation from a midline can cause severe tissue damage.

During ultrasound-guided PIV insertion, the probe orientation that shows the vein in cross-section is called:

Answer: Transverse view

The transverse (short-axis) view displays the vein as a circular cross-section, which is commonly used for initial needle entry visualization.

Which CVAD is best suited for a patient requiring frequent, long-term chemotherapy with intact body image concerns?

Answer: Implanted port

An implanted port is subcutaneous and nearly invisible, making it ideal for patients with body image concerns who need long-term chemotherapy.

What is the primary purpose of using a tourniquet during peripheral IV insertion?

Answer: Dilate the vein to improve visibility and access

A tourniquet causes venous distension by impeding venous return, making veins more prominent and easier to cannulate.
