A nurse is reinforcing teaching with a client who is scheduled for a percutaneous kidney biopsy. Which of the following client statements indicates a need for further teaching?

A. "I will need to lie on my back for several hours after the procedure.": Following a kidney biopsy, the client must maintain strict supine bed rest to apply pressure to the site and prevent hemorrhage. This positioning is essential for stabilizing the clot and monitoring for internal bleeding. Acknowledging this requirement indicates that the client understands the necessary post-procedure safety precautions. B. "It's okay for me to take my anticoagulant the morning of the biopsy.": Anticoagulants significantly increase the risk of uncontrolled bleeding from the highly vascular renal tissue during and after the needle insertion. These medications must be discontinued several days prior to the procedure to ensure normal coagulation parameters. This statement represents a high-risk misunderstanding that requires immediate correction by the nurse. C. "I should avoid taking aspirin before the biopsy.": Aspirin inhibits platelet aggregation and can cause significant hematoma formation or persistent bleeding at the biopsy site. Discontinuing antiplatelet agents is a standard preoperative requirement for any invasive renal procedure. This client statement correctly reflects the necessary pharmacological adjustments needed to ensure a safe procedure. D. "I will report any flank pain or hematuria after the procedure.": Flank pain and blood in the urine are clinical indicators of post-procedural complications like subcapsular hematoma or internal hemorrhage. Early identification of these symptoms allows for rapid intervention and stabilization. The client's awareness of these red-flag symptoms shows an appropriate understanding of the monitoring process.
