VABC Vascular Access Devices & Technologies

Question 1

What is the primary function of a central venous catheter (CVC)?

Accepted Answer

To deliver fluids and medications directly into large veins for long-term access

Answer

To administer medications through the skin

Answer

To collect blood samples only

Answer

To monitor blood pressure in small veins

Question 2

Why are peripherally inserted central catheters (PICC) used in vascular access?

Accepted Answer

They are used for long-term intravenous therapy, with a lower risk of complications

Answer

They are used for short-term medication delivery

Answer

They are used only for blood sampling

Answer

They are used to monitor blood pressure

Question 3

What is the difference between a tunneled and a non-tunneled central venous catheter?

Accepted Answer

Tunneled CVCs are for long-term use and are surgically inserted under the skin

Answer

Tunneled CVCs are for short-term use only

Answer

Non-tunneled CVCs are more secure and easier to insert

Answer

Non-tunneled CVCs are used for long-term access

Question 4

How does a dialysis catheter differ from other vascular access devices?

Accepted Answer

It is specifically designed for hemodialysis, allowing blood removal and return at high volumes

Answer

It is designed for patients receiving chemotherapy

Answer

It is used for blood sampling only

Answer

It is used to deliver long-term nutrition

Question 5

Why is ultrasound used in vascular access procedures?

Accepted Answer

It is used to visualize veins and arteries, improving device placement accuracy

Answer

It is used to monitor blood pressure during procedures

Answer

It helps administer medications during procedures

Answer

It is used to increase the flow of blood

Question 6

What are the advantages of using a midline catheter over a peripheral intravenous (IV) catheter?

Accepted Answer

Midline catheters provide longer-lasting access and are used for more complex treatments

Answer

Midline catheters are used for short-term medication administration

Answer

Peripheral IVs are more stable and have fewer complications

Answer

Midline catheters are only used for blood sampling

Question 7

How can catheter-related bloodstream infections (CRBSIs) be prevented?

Accepted Answer

By following strict hygiene practices and ensuring sterile conditions during catheter insertion and maintenance

Answer

By using only non-tunneled CVCs

Answer

By limiting the number of catheters used in patients

Answer

By avoiding the use of ultrasound during insertion

Question 8

What are the common complications associated with vascular access devices?

Accepted Answer

Common complications include infection, thrombosis, occlusion, and mechanical issues like dislodgement

Answer

Infection, thrombosis, and catheter occlusion are not complications of vascular access devices

Answer

Only infection is a common complication of vascular access devices

Answer

Mechanical issues are only relevant in non-tunneled catheters

Question 9

Why are patient education and follow-up important in vascular access device management?

Accepted Answer

Patient education and follow-up ensure proper care, reducing complications and improving outcomes

Answer

Patient education is unnecessary in vascular access device management

Answer

Patient education only applies to the insertion process

Answer

Follow-up care is only necessary in non-tunneled catheters
