Final answer:
Hypovolemic shock, caused by excessive loss of blood volume, is most likely to occur due to severe diarrhea. Symptoms of hypovolemic shock include rapid heart rate, weak pulse, cool and clammy skin, rapid breathing, and thirst.
Step-by-step explanation:
Hypovolemic shock, or a type of circulatory shock caused by excessive loss of blood volume, is most likely to occur due to severe diarrhea. In young children, severe diarrhea can lead to fluid losses that can result in hypovolemic shock. Symptoms of hypovolemic shock include a rapid, almost tachycardic heart rate, weak pulse, cool and clammy skin, rapid shallow breathing, hypothermia, thirst, and dry mouth. The treatment for hypovolemic shock generally involves providing intravenous fluids to restore fluid levels and various drugs such as dopamine, epinephrine, and norepinephrine to raise blood pressure.
