A nurse is assessing a client who is to have IV urography. Which of the following data should indicate to the nurse that this procedure is contraindicated for this client?

Choice A reason: Claustrophobia may cause discomfort during imaging procedures like MRI, but IV urography typically does not involve enclosed spaces. It is not a contraindication, though anxiety management may be needed. Choice B reason: The presence of a metal rod in the tibia is relevant for MRI procedures due to magnetic interference, but it does not affect IV urography, which uses X-ray and contrast dye. Choice C reason: An allergy to shellfish is a red flag for IV urography because it may indicate a sensitivity to iodine-based contrast agents. These agents are commonly used in urography and can trigger severe allergic reactions in susceptible individuals. Pre-procedure screening for contrast allergies is essential. Choice D reason: Rosiglitazone is a medication used to manage type 2 diabetes. While it has cardiovascular risks, it does not contraindicate IV urography. However, renal function should be monitored in diabetic patients undergoing contrast studies.
