Renee, a nurse, is first on the scene of a car accident. The driver has been thrown from the car, and even from 15 feet away, Renee knows that a large artery in the man's leg has been severed. How does she know this? What two things does she see? Renee stops the bleeding, but the ambulance has not arrived. She wants to assess the man's condition after he has lost so much blood. She cannot take a blood pressure, but what other vital sign can be helpful? Explain. If Renee could take a blood pressure reading, what might it be? Might it be within the normal range? Explain.
