A nurse is caring for a client who has an implanted venous access port. Which of the following should the nurse use to access the port?

A. An angiocatheter. This is used for peripheral IV access, not for accessing implanted venous ports. It is not designed to penetrate the septum of a port safely or effectively. B. A 25-gauge needle. This needle is too small and not suitable for accessing a venous port, as it may not deliver adequate flow and can damage the port's septum. C. A noncoring needle. Also known as a Huber needle, this is the correct choice for accessing an implanted port. It has a deflected tip that prevents coring (removing pieces of the port’s septum), preserving the integrity of the port and reducing the risk of damage or infection. D. A butterfly needle. These are typically used for short-term venous access or blood draws and are not appropriate for accessing an implanted port. They lack the design necessary to protect the septum of the device.
