After a central line catheter is placed, what should the RN do before starting treatment?

In the context of managing patient safety and ensuring proper protocol following the placement of a central line catheter, it is crucial to have proper documentation of the placement. This documentation, generally obtained from the radiologist, serves as confirmation that the catheter is positioned correctly and effectively, which minimizes the risk of complications such as misplacement or pneumothorax. Having accurate and written verification is essential for the RN to proceed safely with any subsequent treatment.

The other actions, while important, don't address the immediate necessity of confirming the catheter's position through proper documentation. Verifying patient identity, checking the IV site for patency, or administering test doses are all relevant procedures; however, they should follow the confirmation of catheter placement to ensure patient safety and the effectiveness of treatment.
