Two 5-year-old girls, best friends, held hands in Tolson’s office at Van Ness Elementary School in Washington, D.C., one saying she didn’t feel well. Tolson, the school nurse, asked, “How long has your stomach been hurting?” “It just started,” she said.

The other one said her head hurt last night, too. Tolson knew she had a history of fevers, so she checked her temperature and asked her what she ate, whether she went to the bathroom, and whether her head still hurt. It could be that these two little girls that went to Tolson’s office were fine. Or maybe they had mental problems. And that is what school nurses have to judge every day.

School nurses generally get very little training when it comes to mental health. Mazyck said she herself was astounded when she was a school nurse. She saw upset, anxiety, sadness and students who didn’t even know what to do to calm themselves down. She never expected these. So Mazyck went back to school for a graduate degree in counseling (咨询) and now she focuses on getting nurses more training in mental health.

Sharon Stephan, who co-directs the National Center for School Mental Health at the University of Maryland, tells nurses there are two simple questions to ask themselves to see if a child needs help:

Is the student acting or behaving differently than he/she was before?

Is the student somehow far outside the norm (标准) of what you would expect?

The only time everyone pays attention is when there’s a tragedy(悲剧), like a school shooting. However, we actually can catch the students who might harm others and recognize the students who might want to kill themselves.

Mental health is ranked one of the top problems all school nurses deal with, and school nurses need to be better at it.
