Identify the following image?
Appeared in: NORCET 5 mains
Explanation
- The image displays a catheter inserted into a peripheral vein in the upper arm, which is the defining visual characteristic of a Peripherally Inserted Central Catheter (PICC line).
- Although it is inserted peripherally, its tip is advanced to a large central vein (the superior vena cava), making it a type of central venous access device.
- PICC lines are specifically used for intermediate to long-term intravenous therapy, such as extended courses of antibiotics or chemotherapy.
Why Other Options Were Wrong
- Option B: While a PICC line is technically a type of central line (because its tip is in a central vein), the term 'Central line' in clinical practice commonly refers to a non-tunneled catheter that is inserted directly into a central vein, such as the internal jugular (in the neck) or the subclavian (in the chest). The insertion site in the image is the arm, not the neck or chest.
- Option C: A standard peripheral IV line is much shorter than a PICC line and is typically inserted in the veins of the hand or forearm. It is used for short-term therapy only (usually a few days). The device in the image is inserted in the upper arm and is designed for long-term use.
- Option D: This option is incorrect because the device shown in the image is clearly identifiable as a specific type of medical catheter, a PICC line.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Identification of intravenous access devices based on visual characteristics as background academic context rather than a clinical decision trigger.
- A primary nursing responsibility is the prevention of Central Line-Associated Bloodstream Infections (CLABSI). This involves strict adherence to aseptic technique for all dressing changes, flushing, and medication administration through the PICC line.
- Nurses must educate patients to not allow blood pressure cuffs or tourniquets on the arm with the PICC line, as this can cause catheter occlusion or damage.
- Regular assessment of the insertion site for signs of infection (redness, swelling, pain, drainage) or phlebitis is a critical patient safety measure.
How to Approach the Question
- First, carefully analyze the image to identify key visual cues. Note the specific location of the catheter's insertion site, which is the upper arm.
- Next, read all the options provided: PICC line, Central line, and IV line.
- Recall the definitions and distinguishing features of each type of intravenous access device.
- A standard IV line is short and placed in the hand or forearm.
- A 'central line' is typically inserted directly into a large vein in the neck or chest.
- A PICC line is inserted in the upper arm but extends to a central vein.
