A patient has met with a car accident and has lost a lot of blood. Choose the response that will compensate the most for the blood loss.
Options:
Answer:
B
Solution:
Heart rate represents the speed at which the heart performs the function of pumping blood into the arteries. If a person has extensive blood loss, then the best compensatory response would be an increased heart rate. This is because if the heart rate increases, blood will be pumped into the arteries at a faster rate. Thus, the blood loss will be compensated faster.
