What is an indication of potential internal bleeding?

Excessive sweating
Thirst
Frequent urination
Nausea

The correct answer is: Thirst

Thirst is an indication of potential internal bleeding because it can be a response to a decrease in blood volume and an increase in fluid loss from the body. When internal bleeding occurs, the body may not have enough circulating blood volume to adequately perfuse tissues, leading to symptoms such as rapid heart rate, low blood pressure, and ultimately, a sensation of thirst as the body signals its need for fluids. This is a physiological response aimed at maintaining homeostasis and ensuring that blood volume is restored, especially in cases of significant blood loss. Recognizing thirst as a warning sign can help EMTs identify patients who may be in shock or experiencing critical fluid deficits associated with internal bleeding.
