Device Selection & Insertion Techniques Flashcards

A non-tunneled central venous catheter inserted in an emergency should be replaced within how many days to reduce infection risk?

Answer: 48 hours

CDC guidelines recommend replacing emergency-placed CVCs within 48 hours due to increased infection risk from non-sterile insertion conditions.

When selecting a vein for a midline catheter, the preferred insertion site is:

Answer: Antecubital fossa veins (basilic, cephalic, or median cubital)

Midline catheters are inserted in the antecubital fossa and advance 8–20 cm, terminating below the axilla.

The 'Z-track' technique during PIV insertion is used to:

Answer: Anchor the vein and reduce catheter dislodgement

The Z-track technique involves applying distal traction on the skin to anchor the vein, preventing rolling and aiding successful cannulation.

Which of the following is the LEAST preferred site for peripheral IV placement in an adult?

Answer: Antecubital fossa

The antecubital fossa is least preferred for routine PIVs because arm flexion restricts flow and increases catheter failure rates.

A patient has a known latex allergy. Which CVAD component must the nurse verify before insertion?

Answer: Port septum and catheter materials for latex-free composition

Port septa and some catheter materials may contain latex; latex-free devices must be confirmed for patients with latex allergy.

What technique is used to confirm intravascular placement of a peripheral IV immediately after insertion?

Answer: Observing blood flashback in the catheter hub

Blood flashback into the catheter hub confirms that the needle tip has entered the vascular lumen.

For a pediatric patient under 2 years old requiring IV access, which site is often used when peripheral veins are inaccessible?

Answer: Scalp vein

Scalp veins are commonly used in infants under 2 years when extremity access fails, as scalp veins are prominent and accessible.
