I am also an RN but no kids and I don't do pediatrics. A quick check for meningitis is to have them put chin to chest. If they can do it, probably not meningitis. The most important thing with a kid is to keep them from getting dehydrated. Make them take sips even if they throw it up. They will still get some digested. It is a good sign that the temp came down. I would probably wait until am and see how things are. Fevers are always worse at night. I would give your doctor a call or go to a doctor in a box in the morning. You may be dealing with strep throat. Good luck.
