In Class 2 hypovolemic shock, blood pressure is described as:

• A. Normal
• B. Decreased
• C. Increased
• D. Varied

Answer: (A)

In early hypovolemia (Class II), the body compensates to keep perfusion pressure up. When blood volume falls about 15–30%, baroreceptors trigger a sympathetic response that increases heart rate and contractility and causes vasoconstriction. This raises systemic vascular resistance and helps maintain mean arterial pressure even though the amount of blood available to pump is reduced. Because of these compensations, blood pressure often remains normal in this stage, though the pulse pressure narrows and other signs like tachycardia and tachypnea appear. So the best description is that blood pressure is normal in Class II. Decreased or increased pressures aren’t typical at this stage, and a fluctuating pattern isn’t the characteristic finding.
