Use of the illegal drug MDMA,commonly known as ecstasy,may cause hyperthermia (increased body temperature),which may cause a person to drink a lot of water.In addition,MDMA increases the production of vasopressin.What is the most likely outcome if a person takes MDMA and experiences hyperthermia,increased water intake,and increased vasopressin production?
A)an increase in blood pressure and the production of dilute urine
B)an increase in blood pressure and the production of concentrated urine
C)a decrease in blood pressure and the production of dilute urine
D)a decrease in blood pressure and the production of concentrated urine

MDMA causes hyperthermia, which results in increased water intake. The increased production of vasopressin will cause the kidneys to reabsorb more water and produce concentrated urine. This will increase blood pressure due to the higher concentration of solutes in the blood. Therefore, the most likely outcome if a person takes MDMA and experiences hyperthermia, increased water intake, and increased vasopressin production is an increase in blood pressure and the production of concentrated urine.
