Hey, sorry I just saw this today. I work on a (basically) peds med-surg floor in an exclusively children's hospital. Well, more med- than surg-, haha. I can tell you a lot of the things we usually see: respiratory illnesses (pneumonia, asthma, bronchiolitis/RSV, croup, etc); dehydration/gastroenteritis, MRSA abscesses/cellulitis, CF patients, Crohn's or other chronic GI patients, as-yet unknown-cause abd pain, seizures, meningitis, and several "chronic" patients with multiple health problems, in for one reason or another, most often respiratory issues, or problems with their G-tubes. We often have children with trachs and/or home vents, usually only one or two at the most at a time (on a floor that holds up to 45 patients). What else? Oh, we occasionally get children/teens who have attempted suicide but are not yet medically stable enough to go to the psych unit

that is sad; also littler kids who just accidentally got into grandma's heart medicine or the tasty chewable multivitamins. We usually have 4-5 patients apiece, occasionally 6 if it's busy, or 3 if one is especially ill/busy; and have one nurses' aide for every 9-10 patients usually.
Wow, I wrote a book!!! I hope this helps a little bit. Good luck with your decision.
