Final answer:
The food allergy relevant to getting an influenza vaccine is an egg allergy because some flu vaccines contain small amounts of egg proteins. This could potentially cause an allergic reaction in individuals with a severe egg allergy.
Step-by-step explanation:
Among the various food allergies that can place an adult client at risk for a reaction when administering an influenza vaccine, an egg allergy is particularly relevant. This is because some flu vaccines are made using egg-based technology and thus contain small amounts of egg proteins, which could potentially trigger an allergic reaction in someone with a severe egg allergy. Therefore, the correct food allergy that could place the client at risk for a reaction is d. Eggs. It is important to note, however, that according to the Centers for Disease Control and Prevention (CDC), persons with a history of egg allergy who have only experienced hives after exposure to egg should receive any licensed, recommended, and age-appropriate influenza vaccine. For those who have symptoms other than hives (e.g., angioedema, respiratory distress, lightheadedness, or recurrent emesis) or who required epinephrine or another emergency medical intervention, the vaccine should be administered in a medical setting under the supervision of a health care provider able to recognize and manage severe allergic conditions.
