10. In what circumstance would it be appropriate to use a tourniquet?"
A. There are multiple people with life-threatening injuries who need care,
B. The person has a bleeding chest wound,
O C. You do not have dressing and bandages available
D. You cannot access a pressure point to apply pressure.

i would say B

because the device is used to stop blood and a bleeding chest wound you would have to stop it

when you rub, you also apply pressure, that pressure can urge the poop to come out. i think that when your rubbing, you also might be slightly breaking it up and that can further fill the stomach.  

because health skills are tools and strategies and also practical skills are also something you need to learn (like tools and strategies) and put it in reality.
