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 not routinely confirmed by CT scan. Instead, correct placement of a central venous catheter is verified by a chest X-ray immediately after insertion to ensure proper tip location. B. "You will be under general anesthesia for this procedure.": General anesthesia is not required for placement of a nontunneled percutaneous central venous catheter. The procedure is typically performed using local anesthesia and aseptic technique at the bedside. C. "The provider will wear a mask while performing the procedure.": The provider wears a mask, sterile gown, gloves, and cap as part of strict sterile technique during insertion to prevent catheter-related bloodstream infections. D. "Your head will be elevated as high as possible while the catheter is inserted.": The client’s head is not elevated during insertion. Instead, a flat or slight Trendelenburg position is used to distend neck veins and reduce the risk of air embolism.
