FREE IV Venous Access Devices Questions and Answers

Question 1

What is the primary purpose of venous access devices?

Accepted Answer

To allow for the infusion of intravenous fluids and medications

Answer

The primary purpose of venous access devices is to provide a reliable and continuous route for the infusion of intravenous fluids and medications directly into a patient's bloodstream. These devices, such as peripheral IVs or central lines, allow healthcare professionals to administer necessary therapies, draw blood samples, and maintain hydration without repeated needle sticks. This ensures efficient and effective delivery of treatment.

Question 2

Which of the following is a type of venous access device?

Accepted Answer

Peripheral intravenous catheter (PIV)

Answer

A Peripheral Intravenous Catheter (PIV) is a common type of venous access device used for short-term intravenous therapy. It provides direct access to a peripheral vein for administering fluids, medications, or drawing blood. This distinguishes it from other catheters designed for different purposes, such as central venous access or urinary drainage.

Question 3

When should a nurse check the patency of a venous access device?

Accepted Answer

Before every medication or fluid infusion

Answer

Checking the patency of a venous access device before every medication or fluid infusion is crucial for patient safety. This ensures the catheter is correctly positioned within the vein and functional, preventing complications like infiltration or extravasation that can occur if the device is occluded or dislodged. Proactive patency checks confirm safe and effective delivery of therapy.

Question 4

What should be done if a venous access device becomes occluded?

Accepted Answer

Attempt to flush the device with saline or a heparinized solution

Answer

If a venous access device becomes occluded, the initial and most appropriate action is to attempt to flush it with saline or a heparinized solution. This gentle maneuver can often dislodge a clot or precipitate, restoring patency without requiring immediate device removal. Only if flushing fails should further interventions, such as device removal, be considered.

Question 5

What is an important consideration when choosing a venous access device for a patient?

Accepted Answer

The expected duration of therapy and patient’s condition

Answer

When choosing a venous access device, the expected duration of therapy and the patient's condition are paramount considerations. Long-term therapy or irritating medications may necessitate a central venous catheter, while short-term needs are met by a peripheral IV. The patient's vein health, medical history, and specific treatment plan also guide the selection to ensure optimal and safe access.
