A nurse is caring for a female client who has recurrent kidney stones and is scheduled for an intravenous pyelogram. Which of the following statements by the client should the nurse report to the provider?

Choice A reason: Adequate fluid intake is encouraged in clients with kidney stones to prevent recurrence. This statement reflects good hydration habits and does not pose a concern for the procedure. Choice B reason: Painful, red-tinged urine may indicate active stone passage or hematuria, which is expected in this population. While it should be documented, it does not contraindicate the procedure unless infection is suspected. Choice C reason: Menstrual history is relevant for pregnancy screening but ending a period 2 days ago does not raise immediate concern. Standard pre-procedure pregnancy testing would still apply. Choice D reason: A history of hives from shellfish suggests a potential allergy to iodine-based contrast agents used in intravenous pyelograms. This must be reported to the provider immediately, as it may require premedication or alternative imaging to prevent anaphylaxis.
