Final answer:
The nurse should interpret the client's statement as a misunderstanding about the use of the new AV fistula; it needs time to mature before the existing catheter can be removed.
Step-by-step explanation:
The nurse should interpret the client's statement as indicating a misunderstanding about the immediate use of the new arteriovenous (AV) fistula for hemodialysis. While the client expresses a desire to remove the existing hemodialysis catheter right after the creation of the fistula, it is important to understand that a new AV fistula generally requires a period of time to mature before it can be used for dialysis treatments. This maturity period typically lasts several weeks to months during which the fistula strengthens and the blood vessels enlarge to accommodate the increased blood flow needed for hemodialysis. Therefore, the existing catheter usually remains in place until the fistula has properly matured and is deemed functional by a healthcare provider.
The nurse should take this opportunity to educate the client on the process of fistula maturation and the importance of keeping the catheter until the fistula is ready for use. Clearing up misconceptions can help manage the client's expectations and ensure that they are prepared for the postoperative care and timeline associated with the new fistula.
