Which of the following symptoms is a sign of non-compressible hemorrhage?

Non-compressible hemorrhage refers to bleeding that cannot be controlled by direct pressure or compression and is often associated with significant internal injury. Bruising, or ecchymosis, shows that bleeding has occurred beneath the skin, indicating that vessels have ruptured. This suggests the presence of bleeding in a non-compressible area, as it typically involves underlying tissue or organs rather than an external injury.

Hemoptysis, which is the coughing up of blood, can also be a sign of non-compressible hemorrhage indicating internal injury, particularly in the respiratory system. This symptom arises from bleeding that occurs within the lungs or the airway and cannot be managed by external measures.

The combination of bruising and hemoptysis illustrates two different manifestations of internal bleeding rather than external bleeding, as they are both indicative of significant trauma to internal structures. This context is crucial for understanding why both signs contribute to the identification of non-compressible hemorrhage.
