Jodi Bobbitt, the school nurse at William Ramsay Elementary in Alexandria, Virginia, is always ready to see children with a wide range of injuries and illnesses. One day during the first week of school, the parade started before the first bell when a little girl walked in with red, irritated eyes.

Then it got busy.

As the only school nurse at this suburban Washington, D.C., elementary school, Bobbitt’s responsibilities extend beyond treating scraped knees and sniffles for the school’s 600 pupils. At her under-the-sea-themed clinic, she administers medications, teaches kids about health care, and conducts routine health screenings. As the school nurse, she also serves as a public health point person — tracking student vaccinations, linking parents to local health care resources, and communicating sometimes difficult messages to them, such as warnings about sexually transmitted diseases and signs of depression.

It’s a full plate, but Bobbitt considers herself lucky. In a previous school nursing job, she split her time between two buildings within the same school district — some years three.
