How much blood loss can a fist-sized hematoma cause?

5% blood loss
10% blood loss
15% blood loss
20% blood loss

The correct answer is: 10% blood loss

A fist-sized hematoma typically indicates significant bleeding that has occurred beneath the skin, generally due to trauma. The size of the hematoma can be an indicator of how much blood has pooled in the tissue. The correct answer reflects a standard estimate of blood loss in relation to the size of a hematoma. A hematoma about the size of a fist can indeed represent approximately 10% of a person's total blood volume, depending on factors such as the individual's size and overall health. This figure helps EMTs and medical professionals understand the extent of blood loss and the potential for hypovolemic shock, allowing for appropriate interventions. Understanding this relationship between hematoma size and blood loss is crucial in pre-hospital care as it assists EMTs in prioritizing treatment and transport decisions for trauma patients.
