A nurse is reinforcing teaching with a client who is scheduled for an intravenous pyelogram. Which of the following statements by the client indicates an understanding of the teaching?

A. "I do not need to sign a consent form before this procedure.": An intravenous pyelogram is an invasive diagnostic procedure that uses contrast dye, so informed consent is required. The client must understand the risks, benefits, and alternatives before the procedure is performed. B. "I can have a meal up to 2 hours before the procedure.": Clients are typically instructed to remain NPO for several hours before an intravenous pyelogram to reduce the risk of aspiration and improve visualization of the urinary tract. Eating shortly before the procedure is not recommended. C. "I will feel a warming sensation after the injection of the dye.": A transient feeling of warmth or flushing is a common and expected response after contrast dye administration during an intravenous pyelogram. Recognizing this normal sensation helps reduce anxiety and indicates appropriate understanding of what to expect during the procedure. D. "I should limit my fluid intake for 2 days after the procedure.": Clients are encouraged to increase fluid intake after the procedure to help flush the contrast dye from the kidneys. Limiting fluids could increase the risk of nephrotoxicity and delay dye excretion.
