What are the signs of hypovolemic shock?

• A. Fever, bradycardia, and increased ambition
• B. Tachycardia, hypotension, and altered mental status
• C. Jaundice, high fever, and muscle rigidity
• D. Dyspnea, edema, and abdominal distension

Answer: (B)

Hypovolemic shock occurs when there is a significant loss of blood volume, leading to inadequate perfusion of tissues and organs. The signs associated with hypovolemic shock primarily stem from the body’s response to the decreased blood volume and subsequent reduction in oxygen delivery.

Tachycardia is a common compensatory mechanism; as blood volume decreases, the heart rate increases in an effort to maintain adequate cardiac output and tissue perfusion. Hypotension, or low blood pressure, is a direct result of the reduced circulating blood volume, indicating that the heart may not be able to pump enough blood to meet the body’s demands. Altered mental status arises due to decreased cerebral perfusion, which can result in confusion, disorientation, or lethargy as the brain receives insufficient blood flow.

The other options reflect signs and symptoms related to different medical conditions that do not apply to hypovolemic shock. For instance, the first option describes symptoms typically associated with infections or fever rather than shock. The third option lists signs related to hepatic dysfunction or possibly severe infection but does not pertain to hypovolemic shock. The fourth option includes symptoms that suggest fluid overload or respiratory distress rather than the low fluid volume situation characterized by hypovole
