Hypovolemic shock occurs when:

Hypovolemic shock occurs when:

• A. At least 10% of blood volume is lost
• B. Low fluid volume leads to inadequate perfusion
• C. Systolic BP is less than 100 mm Hg
• D. Clotting ability of the blood is enhanced

Answer: (B)

Hypovolemic shock is a critical condition that arises when there is a significant decrease in blood volume, typically due to severe fluid loss from bleeding, trauma, dehydration, or other causes. The key characteristic of hypovolemic shock is that this low fluid volume leads to inadequate perfusion of vital organs. When the blood volume is insufficient, the body cannot deliver enough oxygen and nutrients to tissues, resulting in decreased cellular function and potential organ failure. Option B accurately describes this physiological process. Inadequate perfusion means that vital organs—such as the brain, heart, and kidneys—do not receive the blood flow they need to function properly, leading to serious health complications. The body's compensatory mechanisms may initially attempt to maintain blood pressure and perfusion, but as fluid loss continues, these mechanisms can be overwhelmed, leading to a downward spiral of organ dysfunction. The other options do not capture the fundamental nature of hypovolemic shock. For instance, while losing a certain percentage of blood volume can be a contributing factor, the specific threshold (like losing at least 10%) doesn't necessarily define hypovolemic shock. Systolic blood pressure being below 100 mm Hg may be a sign of shock but isn't sufficient alone to diagnose it
