A nurse is preparing a client for a kidney biopsy. Which of the following actions should the nurse take?

A. Instruct the client to remain NPO 8 hr before the procedure: Kidney biopsies are typically performed under local anesthesia with sedation, not general anesthesia, so strict NPO status is usually unnecessary unless sedation is planned. Routine NPO for 8 hours is not a standard requirement for all clients. B. Review the coagulation studies before the procedure: Kidney biopsy involves inserting a needle into highly vascular renal tissue, which carries a significant risk of bleeding. Reviewing coagulation studies (e.g., PT, INR, platelet count) ensures that the client’s blood clotting ability is adequate and minimizes the risk of post-procedure hemorrhage, making this a priority action. C. Inform the client that the biopsy is performed while lying supine during the procedure: Kidney biopsies are usually performed with the client lying prone, often with a pillow under the abdomen to better expose the kidney. D. Administer a cleansing enema before the procedure: A cleansing enema is not required for a kidney biopsy because the procedure does not involve the gastrointestinal tract. Administering one is unnecessary and does not affect the safety or success of the biopsy.
