Final answer:
The symptoms described are indicative of hypovolemic shock, a condition caused by a significant loss of blood volume and treated with fluid replacement and specific medications.
Step-by-step explanation:
A person presenting with decreased blood pressure, rapid pulse, and cold clammy skin is likely suffering from hypovolemic shock, which is a type of circulatory shock caused by excessive loss of blood volume. Common causes of hypovolemic shock in adults include hemorrhage, whereas in children it may be due to fluid losses from severe vomiting or diarrhea. The treatment primarily involves fluid replacement through intravenous fluids and medications like dopamine, epinephrine, and norepinephrine to help raise blood pressure.
