Which term means abnormally low blood volume?

• A. Hypovolemia
• B. Hypertension
• C. Hypotension
• D. Hyperventilation

Answer: (A)

When the body has less circulating blood than normal, the term used is hypovolemia. It directly describes a reduced intravascular volume, such as after a hemorrhage or severe dehydration, and it helps explain why cardiac output and tissue perfusion can drop. Hypertension means high blood pressure, which is about pressure, not volume. Hypotension refers to low blood pressure and can result from many causes, including low volume, but it describes the pressure state rather than the amount of blood itself. Hyperventilation is rapid breathing and has nothing to do with blood volume. So hypovolemia is the precise term for abnormally low blood volume.
