Which of the following is not a sign of internal bleeding?

Increased sweating does not typically indicate internal bleeding. While sweating can occur due to various conditions, such as shock, anxiety, or heat exhaustion, it is not a specific sign associated with internal bleeding.

In contrast, coughing blood, a swollen abdomen, and bruising on the skin are all common indicators that may suggest the presence of internal bleeding. Coughing blood (hemoptysis) may signify injury or disease affecting the lungs or other internal organs. A swollen abdomen can occur when blood accumulates in the abdominal cavity, potentially from trauma or an internal injury. Bruising on the skin can be a result of blood leaking out of vessels due to trauma, indicating an injury that might lead to internal bleeding. Therefore, recognizing these specific signs is crucial for accurately assessing potential internal bleeding in a victim.
