Before using a newly placed CVAD for IV antibiotics, what must be verified?

• A. Tip position by chest X-ray
• B. Patency with a 5 mL syringe
• C. Patient's consent
• D. Blood return presence

Answer: (A)

Verifying the catheter tip position with a chest X-ray is essential before using a newly placed CVAD for IV antibiotics because it confirms the catheter sits at a central venous location, typically the lower superior vena cava near the cavoatrial junction. This placement ensures the infused antibiotics enter the central circulation safely and reduces the risk of complications from misplacement, such as infusing into smaller veins or causing vessel injury.

Patency checks, like flushing with a syringe, are important to ensure the lumen can be cleared, but they don’t tell you where the tip is or guarantee safe delivery through the central route. Blood return can indicate the lumen isn’t occluded, but its presence or absence is not a reliable confirmation of correct tip location. Patient consent is necessary for procedures in general, but it doesn’t address the specific safety requirement for starting infusion through a newly placed CVAD.

So, the required verification before using the catheter for antibiotics is confirming tip position by chest X-ray.
