Do you have a nursing degree? If not I would start there. If so, maybe try subbing first, that way you get your feet wet and see what it is like without the commitment. Not only that, but in some places school nursing jobs
are hard to come by, so subbing gets your foot in the door for when a full-time position comes open.
The vomit-phobe part...We deal with a lot of vomit. A. LOT. Puke on their pants, in their hair, on their shoes. Guess who has to help clean the littles up. You. I don't know anyone that particularly likes vomit, but if it is something that you can't get past, this probably isn't the specialty for you. I've eaten lunch with a puker four feet away. (Hey, the lunch had already been nibbled on for over an hour!)
We do have a nice schedule, but there is a lot more to it that that. We do a lot paperwork. I am in charge of keeping 500 students complaint on immunizations, vision, dental, physical paperwork. There are screenings. And there's the unknown. You never know what will walk through your door. One day you might've only done ice packs, band-aids, and saltines all day then the next day you epi-penned a kid, sent out an asthma attack, helped a glucose of 29, and called a parent to pick up their child with an obvious ankle break. And you are the only medical professional in the school, no one else to consult (except the fine co-workers of allnurses). So those are some things to think about.
All that said. I absolutely LOVE my job. It sounds cliche, but I've not once got up in the morning and said "Ugh, I really don't want to go to that place today..." And for that, I am blessed.
