Question

You have been dispatched to a residence where a woman lacerated her arm after falling while holding a drinking glass. She informs you that when she was first cut, blood spurted from the wound, and then within a second or two, it subsided to a mere trickle. She asks why this would happen. Which one of the following is the correct response?

A) "Blood has the ability to clot within a second or two of injury."
B) "Blood vessels tend to constrict quickly once they are injured."
C) "Red blood cells will quickly repair the injury to the blood vessel."
D) "The skin around the injured blood vessels quickly swells and stops bleeding."

Answer 1

The answer is B.

Step-by-step explanation:

According to the details given in the example, because she cut a blood vessel, the blood vessel, using the muscles along the walls of the vessel, constricted as quickly as possible once it was cut to be able to stop the bleeding. So the answer is option B.

I hope this answer helps.
