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

A. Administer a cleansing enema before the procedure.: Renal biopsies focus on the retroperitoneal space and do not typically require a bowel preparation like an enema. While clearing the bowel is necessary for gastrointestinal procedures, it does not improve the safety or visualization of a percutaneous kidney biopsy. Standard preparation focuses on coagulation status and patient positioning rather than intestinal evacuation. B. Inform the client that the biopsy is performed while lying supine during the procedure.: The kidneys are located retroperitoneally, and a percutaneous biopsy is usually performed with the client in the prone position. This allows the provider direct access to the posterior aspect of the kidney through the flank. Supine positioning is utilized after the procedure to provide pressure and prevent hemorrhage, not during the needle insertion. C. Instruct the client to remain NPO 8 hr before the procedure.: While clients should have a light meal or limited intake, a strict 8-hour fasting period is not always mandatory for a local procedure unless heavy sedation is planned. The primary concern for a renal biopsy is the risk of bleeding rather than aspiration under general anesthesia. Maintaining a baseline hydration status is often preferred for renal perfusion. D. Review the coagulation studies before the procedure.: The kidneys are highly vascular organs, and a biopsy carries a significant risk of internal hemorrhage or subcapsular hematoma. The nurse must verify that the prothrombin time, international normalized ratio, and platelet count are within normal limits. Correcting any coagulopathy is essential to prevent uncontrolled bleeding during and after the needle aspiration.
