What type of shock can be caused by long bone or pelvic fractures?

1. Neurogenic Shock

2. Exogenous Hypovolemic Shock

3. Anaphylactic Shock

4. Septic Shock

The correct answer is: Exogenous Hypovolemic Shock

The correct answer is exogenous hypovolemic shock, which can occur as a result of long bone or pelvic fractures. In such cases, major vascular structures can be disrupted, leading to significant blood loss. This loss of blood volume decreases the overall circulating volume in the body, which can severely affect perfusion to vital organs and tissues. In the context of trauma, particularly from fractures, the body may lose blood externally or internally. The pelvis and long bones may serve as sources for considerable hemorrhage due to their vascular supply. Consequently, the severity of blood loss from these injuries can lead to hypovolemic shock, characterized by a drop in blood pressure, rapid heart rate, and signs of inadequate perfusion. Understanding the underlying mechanism of exogenous hypovolemic shock emphasizes the importance of immediate assessment and intervention in trauma cases. Addressing possible fractures in the management of a trauma patient is critical to prevent further complications associated with significant blood loss.
