What statement indicates a client correctly understands pre-procedure instructions for an IV urography?

The statement about taking a laxative the night before to clear the bowels indicates a correct understanding of pre-procedure instructions for an IV urography. Preparing the bowel is an essential part of the procedure because it helps to ensure clearer images of the urinary tract by reducing the risk of interference from intestinal contents. A clean bowel allows the radiologist to get a better view of the kidneys, ureters, and bladder during imaging.

Proper bowel preparation minimizes the chances of artifacts that could potentially obscure the diagnostic images, hence enhancing the efficacy of the procedure. This preparation is vital and is typically part of the guideline for patients undergoing an IV urography.
