If you want the science part of it because I overcompensate for absolutely no reason and the First Aid merit badge is one of my favorites to teach:
Shock is caused by a sudden drop in blood pressure which slows the flow of oxygen to organs, which is why it can be deadly if left untreated. Unless you cut a major artery (which she didn’t) there wouldn’t be much cause for shock. Shock (adrenaline) caused by fear increases blood pressure. This is so you can run faster from the bear, and also bleed less if it bites you. Blood activates the fight-or-flight response, which may have caused the hyperactivity.
That’s why when you treat for shock, you elevate the legs of the victim. The majority of the blood in your body is in your legs, so elevating them helps move the blood into your core, providing the organs with oxygen.
