VA-BC Device Selection & Insertion Techniques

Question 1

Which device is best for long-term venous access?

Accepted Answer

PICC line

Answer

A PICC (Peripherally Inserted Central Catheter) line is a type of central venous catheter inserted into a peripheral vein and advanced to a large central vein. It is considered best for long-term venous access, typically for weeks to months, for administering medications, fluids, or nutrition, offering greater patient comfort and reduced infection risk compared to short-term devices.

Question 2

Before insertion, which site assessment is essential?

Accepted Answer

Vein accessibility

Answer

Before inserting any venous access device, assessing vein accessibility is crucial to ensure successful and safe cannulation. This involves visually inspecting and palpating the chosen site to identify suitable veins, checking for their size, straightness, elasticity, and absence of previous punctures or scarring. Proper site assessment minimizes complications and improves patient comfort.

Question 3

Which technique is used to locate veins for insertion?

Accepted Answer

X-ray

Answer

While ultrasound is commonly used for real-time vein visualization and guidance during insertion, X-ray, particularly in the form of venography with contrast, can be employed to map the venous anatomy. This technique helps to locate suitable veins, assess patency, and plan for complex vascular access procedures, especially for central lines where a detailed anatomical overview is beneficial before insertion.

Question 4

Which type of catheter is inserted into a central vein?

Accepted Answer

Central venous catheter

Answer

A central venous catheter (CVC) is specifically designed for insertion into a large central vein, such as the subclavian, jugular, or femoral vein. This allows for the administration of medications, fluids, and nutrients directly into the central circulation, as well as for hemodynamic monitoring.

Question 5

Which is an important consideration during device selection?

Accepted Answer

Patient’s lifestyle and therapy

Answer

Device selection must always prioritize the patient's individual needs, including their daily activities, anticipated duration of therapy, and the type of infusate. Considering lifestyle helps ensure the device is comfortable and minimally disruptive, while therapy dictates the necessary catheter type and lumen size for safe and effective treatment delivery.
