Before using a PICC line for TPN, how is proper placement confirmed?

• A. Bedside ultrasound
• B. Chest X-ray
• C. Physical examination of the chest
• D. Magnetic resonance imaging

Answer: (B)

Confirming proper placement after inserting a PICC line for TPN relies on chest X-ray. This imaging verifies that the catheter tip rests in the lower part of the superior vena cava near the cavoatrial junction and checks for any immediate complications, such as a pneumothorax, before the line is used for nutrition. While ultrasound can assist during insertion and physical exam can’t reveal intrathoracic position, the chest X-ray provides a reliable, comprehensive view of the catheter’s course and tip location. MRI isn’t used for this rapid verification due to practicality and accessibility issues.
