Answer 1

A patient is in severe shock and is receiving vasopressin. A student asks the health care professional to explain the rationale for this treatment. The most accurate response by the professional is Antidiuretic hormone causes vasoconstriction to help increase blood pressure.

Answer - Antidiuretic hormone causes vasoconstriction to help increase blood pressure.

Vsopressin is also called antidiuretic hormone, it is formed in the hypothalamus and released by the posterior pituitary.

The main function of this hormone is it increases free water absorption from the renal tubules but it is also a potent vasoconstrictor.

In this case, Vasopressin is prescribed to increase blood pressure and to maintain organ perfusion in shock.
