Which of these is an appropriate treatment for a deep, bleeding wound?
a. walk the person around.
b. remove any embedded object.
c. apply direct pressure.
d. apply a tourniquet.

First of all let us consider what is NOT okay to do to a person with deep and bleeding wound. Logic would dictate against walking a bleeding person around thus we know that's not the most appropriate thing to do among the options.

We also don't remove embedded objects from a deep wound since we do not want the blood to be flowing freely from the hole that the embedded object will create. A direct pressure won't help as a treatment either since this will only temporarily block the pathway of the blood, and in some cases putting pressure to a wound is not necessarily ideal.

This leaves us with applying a tourniquet. This is the most logical thing to do since this would stop the blood from flowing freely out of the bleeding wound and will therefore properly treat the injury.

ANSWER: D. Apply a tourniquet.
