Appeared in: AIIMS Delhi NO- 2019

Explanation

The image shows a catheter inserted into a peripheral vein in the arm.
The catheter is long and is threaded through the venous system until its tip rests in the superior vena cava, a large central vein near the heart.
This specific placement—starting peripherally and ending centrally—is the defining characteristic of a Peripherally Inserted Central Catheter (PICC).

Option A: While a PICC is a type of central venous line, this option is less specific. The term 'Central Venous Line' often refers to non-tunneled catheters inserted directly into the neck (jugular) or chest (subclavian) veins, not peripherally in the arm.
Option B: Intra-arterial lines are placed in arteries (e.g., radial artery in the wrist), not veins. They are used for invasive blood pressure monitoring and obtaining arterial blood samples, not for administering fluids or medications.
Option D: This option is incorrect because the catheter shown in the image is clearly identifiable as a Peripherally Inserted Central Catheter (PICC).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of Vascular Access Devices as background academic context rather than a clinical decision trigger.
Nurses are responsible for the care and maintenance of PICC lines, which includes regular flushing to maintain patency, sterile dressing changes to prevent infection, and monitoring for complications.
Key complications of PICC lines include catheter-related bloodstream infections (CRBSI), thrombosis (blood clots), and catheter occlusion or migration. The nurse must assess the site daily for signs of redness, swelling, pain, or drainage.
It is a critical patient safety measure to avoid taking blood pressure or performing venipuncture on the arm with a PICC line to prevent damage to the catheter and vessel.

How to Approach the Question

First, carefully examine the provided image, paying close attention to the labels and the anatomical structures shown.
Identify the starting point (insertion site) of the catheter. In the diagram, it is in a vein in the arm.
Trace the path of the catheter to its endpoint (tip location). The diagram shows the tip in the superior vena cava, near the heart.
Review the definitions of the options provided. A 'Peripherally Inserted Central Catheter' is one that starts in a peripheral vein and ends in a central vein.
Compare your observations from the image with the definitions. The device in the image perfectly matches the description of a PICC line.
Eliminate the other options based on their definitions: a standard CVC is inserted centrally (neck/chest), and an arterial line is in an artery, not a vein.
