Question: 1 / 400

What is the primary cause of hypovolemic shock?

Severe allergic reaction

Blood or fluid loss

Hypovolemic shock occurs primarily due to a significant decrease in blood volume, leading to inadequate circulation of blood to meet the body's needs. The most common cause of this condition is blood or fluid loss, which can occur due to various factors such as severe hemorrhage from trauma, major surgery, or dehydration from severe burns or gastrointestinal losses (like vomiting or diarrhea). When there is a reduction in blood volume, the heart struggles to pump effectively, causing a drop in blood pressure and reduced perfusion to vital organs. Recognizing blood or fluid loss as the root cause of hypovolemic shock is crucial for timely intervention and treatment to restore circulating volume and stabilize the patient. This makes identifying the primary cause essential in emergency and clinical settings.
