A 53-year-old male patient is scheduled to undergo an endoscopic retrograde cholangiopancreatography (ERCP). The nurse performs an assessment on the patient prior to the procedure. Which of the following health background information from the patient should alert the nurse?


• ERCP uses contrast dye to better visualize pancreatic and biliary ducts.

• A history of a prior allergic reaction to contrast dye is associated with an increased likelihood of a subsequent reaction.

• In the past, a history of an allergic reaction or sensitivity to seafood/shellfish allergy was thought to indicate an increased risk of allergy to contrast/dye containing iodine. This has proven to be untrue and shellfish allergy is no longer considered an absolute contraindication to the administration of IV contrast material. 

• Some patients can be sensitive to iodine-binders used in Povidone but there is no cross-sensitivity between this and iodinated contrast materials.

• Familial history of hypertension is not relevant for the procedure, BP and PR are of normal values, and 8-10 glasses of water intake is also normal and acceptable.
