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 can have a meal up to 2 hours before the procedure." Eating before an intravenous pyelogram (IVP) is not recommended, as fasting is typically required to prevent interference with imaging and reduce the risk of nausea from the contrast dye. Clients are usually instructed to refrain from eating for several hours before the procedure. B. "I should limit my fluid intake for 2 days after the procedure." Increasing, rather than limiting, fluid intake is advised after the procedure to help flush the contrast dye from the kidneys and reduce the risk of nephrotoxicity. Adequate hydration is essential for kidney function following contrast administration. C. "I do not need to sign a consent form before this procedure." An IVP involves the injection of contrast dye, which carries risks such as allergic reactions and kidney impairment. Because it is an invasive diagnostic procedure, informed consent is required before proceeding. D. "I will feel a warming sensation after the injection of the dye." The contrast dye used in an IVP often causes a transient warm or flushed feeling, as well as a metallic taste in the mouth. This is a common and expected reaction, indicating that the client understands the procedure.
