Should I pop a blister or leave it alone?

Leave it intact if possible—the fluid actually protects the raw skin underneath. Only drain it if it's large, in a spot where it'll definitely get worse, or if it's already burst. If you do need to deal with one that's popped, clean it thoroughly, apply antiseptic, and keep it covered to prevent infection.

How do I know if a sprained ankle is serious enough to call for help?

If the person can hobble with support, it's likely mild enough to manage. If they can't walk on it at all, there's severe pain or deformity, or walking makes it significantly worse, call for help. Don't try to be heroic—walking out on a badly sprained ankle can turn a two-week recovery into two months.

What are the early signs of hypothermia I should watch for?

Look for shivering, confusion, fumbling hands, and slurred speech. The dangerous part is the person often insists they're fine because hypothermia affects judgment. If you spot these signs, get them out of wet clothes, add insulation, and give warm sweet drinks if they're conscious and able to drink.
