A patient with a suspected renal tumor is being admitted for an intravenous pyelogram (IVP). The nurse discusses the procedure with the patient in addition to taking a full medical history. Which of these pieces of information reported in the patient’s history should the nurse report to the physician performing the IVP?

The nurse is responsible for identifying factors in the patient’s medical history that may be contraindicated for the procedure or treatment that is ordered for the patient. Since an IVP involves the use of iodinated contrast dye, the patient’s iodine allergy must be reported to the physician to prevent an allergic reaction. The rest of the patient’s medical history is acceptable and reveals no contraindications to the procedure.
