VA-BC Device Selection & Insertion Techniques 3

Question 1

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

Accepted Answer

48 hours

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

Anchor the vein and reduce catheter dislodgement

Answer

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

Question 4

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

Accepted Answer

Antecubital fossa

Answer

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

Question 5

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

Accepted Answer

Port septum and catheter materials for latex-free composition

Answer

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