While admitting a client for a cardiac catheterization, the nurse asks the client about allergies. Which of the following client food allergies should the nurse report to the provider prior to the procedure?

Choice A rationale An allergy to eggs is a critical piece of information to collect before administering certain vaccinations, such as the influenza or yellow fever vaccines, which are often grown in egg embryos. However, an egg allergy does not have a direct contraindication or significant correlation with the contrast media used during a cardiac catheterization. Therefore, while it should be documented in the general medical record, it does not require an immediate urgent report to the provider. Choice B rationale Shellfish allergies were historically thought to be strongly associated with a high risk of allergic reactions to iodinated contrast media used in cardiac catheterization. Although current evidence suggests the link is not a direct cross-reactivity, many clinical protocols still require reporting this allergy. The provider may choose to premedicate the client with corticosteroids or antihistamines to minimize the risk of a radiocontrast induced hypersensitivity reaction, which can range from mild urticaria to life threatening anaphylaxis. Choice C rationale An allergy to gelatin is important to note for certain medications that are delivered in capsule form or for specific vaccines that use gelatin as a stabilizer. However, gelatin is not a component of the iodine based contrast dyes or the local anesthetics used during a cardiac catheterization procedure. While it is important for the overall safety profile of the client, it is not a priority finding that needs to be reported specifically for this procedure. Choice D rationale Yeast allergies are generally not relevant to the cardiac catheterization process or the materials used during the procedure. Yeast sensitivities are more significant when considering certain recombinant DNA vaccines, such as the Hepatitis B vaccine, which may contain trace amounts of yeast protein. Since yeast is not involved in the catheterization equipment, contrast media, or standard peri-procedural medications, this allergy does not require a special report to the medical provider.
