What additional information should a nurse collect before administering the inactivated influenza vaccine?

The correct focus is on assessing the client's sensitivity to eggs. The inactivated influenza vaccine is formulated using egg proteins, which means that individuals with a history of severe allergic reactions to eggs could be at increased risk for an adverse reaction to the vaccine. Therefore, it is critical for nurses to inquire about any known allergies to eggs before administering the vaccine, as this information directly relates to the safety and appropriateness of the vaccination for the client.

While an immunization history, current temperature, and allergies to antibiotics are relevant pieces of information, they do not have the same direct implications for the safety of administering the influenza vaccine. Immunization history is important for ensuring that the client is up to date on vaccinations, current temperature can indicate an acute illness, and antibiotic allergies are generally not related to vaccine administration. Thus, the sensitivity to eggs is the most pertinent information needed prior to vaccination.
