A nurse is teaching a client who is to undergo placement of a nontunneled percutaneous central venous access device. Which of the following statements should the nurse include in the teaching?

Rationale: A. "Placement of the catheter is confirmed by a CT scan.": Catheter placement is typically confirmed by a chest X-ray, not a CT scan, to verify correct positioning and rule out complications such as pneumothorax. CT imaging is not routine for this purpose. B. "You will be under general anesthesia for this procedure.": Placement of a nontunneled percutaneous central line is usually done under local anesthesia with possible mild sedation. General anesthesia is not required for this relatively short and minimally invasive procedure. C. "The provider will wear a mask while performing the procedure.": A mask, along with sterile gloves, gown, and drape, is worn to maintain sterile technique and reduce the risk of catheter-related bloodstream infections. This is standard protocol during central line insertion. D. "Your head will be elevated as high as possible while the catheter is inserted.": The client is usually placed in the Trendelenburg position (head down) during catheter insertion to distend neck veins and reduce the risk of air embolism—not in a high head-elevated position.
