Which influenza vaccine would the nurse administer via the intranasal route?

The correct choice for the influenza vaccine administered via the intranasal route is FluMist. FluMist is a live attenuated influenza vaccine (LAIV) that is specifically designed for nasal administration, making it a convenient option for patients who may prefer not to receive an injection. This form of vaccination allows for a needle-free experience, which can be particularly beneficial for children or those with a fear of needles.

Other vaccinations mentioned, such as Fluarix, Fluvirin, and Fluzone, are inactivated vaccines that are administered via intramuscular injection. While they are effective in preventing influenza, their method of administration is different from that of FluMist, reinforcing the unique characteristic of the nasal route for FluMist. Thus, when considering routes of administration, it is essential to understand that only FluMist is formulated for intranasal delivery, making it the appropriate choice in the context of this question.
