Before a cerebral angiography, which allergy should the nurse assess the client for?

• A. Allergy to salmon
• B. Allergy to iodine or shellfish
• C. Excessive weight
• D. Claustrophobia

Answer: (B)

A cerebral angiography involves the use of contrast media, which often contains iodine. Therefore, assessing the client for an allergy to iodine or shellfish is critical. Shellfish allergies can be indicative of a potential allergy to iodine because they both contain similar proteins. If a patient has a history of allergic reactions to iodine or shellfish, there is a risk of a severe allergic reaction or anaphylaxis during the procedure. Understanding this allergy helps the nurse to notify the healthcare provider to consider alternative imaging methods or a different type of contrast media that does not contain iodine, thereby ensuring the safety of the patient during the angiography. While assessing for other concerns like excessive weight or claustrophobia can be relevant in certain contexts, they are not as critical as determining an allergy to substances that could trigger a serious reaction during a procedure that involves iodine-based contrast.
