An adult patient is brought into the emergency room of a local hospital. The EMTs report the patient lost about 300 cc (cubic centimeters or milliliters) of blood. Is this life-threatening?
A. Yes; 300 cc represents about 1/6 of the body's total blood volume of 2 liters.
B. No; most adults have 4-6 liters of blood, so a loss of 300 cc would not be life-threatening.
C. Yes; 300 cc represents about 1/3 of the blood's volume.
D. No; most adults have more than 7 liters of blood, so a loss of 300 cc would not be life-threatening.
