A nurse is assessing a client for allergies prior to administering the influenza vaccine.
The nurse should identify that an allergy to which of the following foods is a contraindication to receiving this vaccine?

Choice A rationale:

Hyperthyroidism is not a contraindication for niacin use. Niacin is used to lower LDL cholesterol levels and has no specific contraindications related to thyroid disorders.

Choice B rationale:

Asthma is not a contraindication for niacin use. Niacin does not interact with asthma medications or worsen asthma symptoms, so it is not contraindicated in individuals with asthma.

Choice C rationale:

High blood pressure is not a contraindication for niacin use. In fact, niacin can help lower blood pressure and improve overall cardiovascular health. It is often prescribed to individuals with high blood pressure and elevated cholesterol levels.

Choice D rationale:

Active liver disease is a contraindication for niacin use. Niacin can cause liver damage, and individuals with active liver disease should avoid niacin therapy to prevent further harm to the liver. Monitoring liver function tests is crucial in patients taking niacin to ensure their liver health.

Choice A rationale:

Shellfish allergies are not a contraindication to receiving the influenza vaccine. The vaccine contains no shellfish-derived ingredients.

Choice B rationale:

Egg allergies are a contraindication to receiving the influenza vaccine. Traditionally, most influenza vaccines are prepared using eggs and can provoke allergic reactions in individuals allergic to eggs. However, individuals with a mild egg allergy can often receive the vaccine under medical supervision. It is crucial to assess the severity of the egg allergy and consult with an allergist or immunologist before administering the vaccine.

Choice C rationale:

Gelatin allergies are generally not a contraindication to receiving the influenza vaccine. While some vaccines contain gelatin, it is not a component of all influenza vaccines. If the specific vaccine being administered contains gelatin, it should be avoided in individuals with a gelatin allergy.

Choice D rationale:

Milk allergies are not a contraindication to receiving the influenza vaccine. Milk or dairy products are not typically included in the influenza vaccine formulation.
