A class II hemorrhage is a loss of what percent?

• A. 15-30%
• B. 0-15%
• C. >40%
• D. 30-40%

Answer: (A)

Hemorrhagic shock is staged by how much blood has been lost, which helps predict stability and guide resuscitation. A moderate loss corresponds to about 15–30% of circulating blood volume, which is labeled as class II. At this level the patient typically shows tachycardia and an increased respiratory rate, and blood pressure may still be normal or only mildly low, with perfusion starting to decline but not yet in full shock. By contrast, smaller losses (0–15%) are class I, larger losses (30–40%) are class III, and very large losses (>40%) are class IV with more evident shock and organ hypoperfusion. So the range for class II is 15–30%.
