When preparing a client for an intravenous pyelogram (IVP), it is essential for the nurse to take which action?

A. Notifying the healthcare provider about allergies to iodine or shellfish is crucial, as IVP contrast agents often contain iodine, and allergic reactions can occur. This is a safety measure that can prevent adverse reactions. B. While keeping the legs straight may be necessary during the procedure, there is no requirement for them to be kept straight for 6 to 8 hours afterward. C. While hydration is important, the focus should be on hydration after the procedure to help flush out the contrast material rather than specifically drinking large volumes before the procedure. D. Inserting an indwelling urinary catheter is not routinely required for IVP unless specified by the healthcare provider; preparation usually focuses on the client’s hydration and allergy history.
