VA-BC Catheter Types 4

Question 1

Which catheter is MOST appropriate for a patient needing intravenous antibiotics for 3 weeks at home?

Accepted Answer

Peripherally inserted central catheter (PICC)

Answer

A PICC is appropriate for intermediate-term (1–6 weeks) outpatient IV antibiotic therapy, combining central access with suitability for home care.

Question 2

The French (Fr) scale used to measure catheter size refers to:

Accepted Answer

The outer circumference divided by π, approximating outer diameter in mm

Answer

The French scale equals the outer circumference in millimeters divided by π, so 1 Fr ≈ 0.33 mm outer diameter.

Question 3

A patient's implanted port has not been accessed in 4 weeks. Per INS standards, the port should be flushed with:

Accepted Answer

Heparinized saline (10–100 units/mL) every 4 weeks when not in use

Answer

INS standards recommend flushing implanted ports every 4 weeks when not in use with heparinized saline to maintain patency.

Question 4

Which insertion site for a non-tunneled CVC carries the HIGHEST risk of catheter-related bloodstream infection (CRBSI)?

Accepted Answer

Femoral vein

Answer

The femoral site has the highest CRBSI risk due to proximity to perineal flora and difficulty maintaining a sterile dressing.

Question 5

What is the clinical significance of a 'reverse taper' design in PICC catheters?

Accepted Answer

The catheter narrows at the tip to reduce vessel trauma on insertion

Answer

A reverse taper PICC narrows at the insertion tip (smaller outer diameter) to minimize vessel trauma while maintaining a larger body for adequate flow.
