What are common signs of internal bleeding?

The presence of swelling, bruising, or signs of shock such as faintness and clammy skin during assessments are indeed common signs of internal bleeding. These indicators arise from the body's response to a significant loss of blood volume or injury to internal structures.

Swelling may occur due to hematomas forming as blood leaks into tissues, while bruising can be a visible manifestation of internal damage. Signs of shock, including faintness or clammy skin, suggest that the body is struggling to maintain adequate blood supply to vital organs due to reduced circulating blood volume, often a result of internal bleeding. This could lead to symptoms like rapid breathing, confusion, or weakness as the body reacts to the perceived emergency.

The other options, while they may present various medical conditions, do not reflect typical clinical signs of internal bleeding. For instance, excessive sweating and high blood pressure are not directly related to internal bleeding. Increased heart rate can be a symptom of many conditions, and increased appetite is generally not a sign associated with bleeding. Visible bleeding and clear fluid discharge might suggest external injuries or specific medical issues, but they do not directly pertain to the assessment of internal bleeding within the body.
