When screening a patient for an intravenous urogram procedure, which of the following should be asked?

When screening a patient for an intravenous urogram (IVU) procedure, it is essential to ask about previous iodine contrast reactions. This is because iodine-based contrast agents are commonly used in medical imaging to enhance the visibility of structures in the body, particularly the urinary tract in this case. A history of an allergic reaction or adverse response to iodine contrast can lead to serious complications during the procedure, such as anaphylaxis or nephrotoxicity, particularly in patients with pre-existing kidney conditions.

Therefore, understanding the patient's history regarding iodine contrast reactions is critical in evaluating the risks and determining a safe course of action for the IVU. This will help healthcare providers to possibly consider alternative imaging methods or premedication protocols when a patient has a known allergy or sensitivity to iodine contrast materials. Other options, while they may provide useful medical history information, do not directly pertain to the immediate concerns related to the safety of administering iodine contrast agents during an intravenous urogram.
