IV Venous Access Devices 5

Question 1

An intraosseous (IO) device is considered appropriate when:

Accepted Answer

Emergent vascular access is needed and IV access cannot be rapidly established

Answer

IO access is a rapid emergency alternative when IV access fails in critical situations; it is not appropriate for non-emergent or long-term use.

Question 2

A patient with a tunneled catheter reports that the external portion of the catheter has been partially pulled out by about 2 cm. The nurse should FIRST:

Accepted Answer

Clamp the catheter, notify the provider, and do not use until evaluated

Answer

A dislodged tunneled catheter should be clamped and the provider notified immediately; reinserting or using it before radiologic confirmation is unsafe.

Question 3

Which laboratory finding is MOST associated with catheter tip malposition in the right atrium rather than the SVC?

Accepted Answer

Cardiac arrhythmias noted on telemetry

Answer

A catheter tip positioned in the right atrium can irritate the cardiac conduction system, causing arrhythmias such as PACs or PVCs.

Question 4

The appropriate volume for flushing a peripheral IV catheter before and after each medication administration per INS standards is:

Accepted Answer

5–10 mL normal saline

Answer

INS recommends 5–10 mL of preservative-free normal saline to flush peripheral IVs before and after medication administration.

Question 5

A power-injectable PICC is distinguished from a standard PICC by its ability to:

Accepted Answer

Withstand high-pressure injection rates required for CT contrast (up to 5 mL/sec)

Answer

Power-injectable PICCs are rated to tolerate the high-pressure injections (up to 300 psi) needed for contrast CT imaging.
