Which of These is Not a Short-Term Response to a Decrease

Question

Which of these is not a short-term response to a decrease in blood pressure?
A) release of EPO
B) increase in heart rate
C) increase in heart contractility
D) peripheral vasoconstriction
E) release of epinephrine and norepinephrine

Accepted Answer

The release of EPO (erythropoietin) is a long-term response to a decrease in blood pressure, as it stimulates the production of new red blood cells which can help increase blood volume and therefore blood pressure. The other options listed are all short-term responses to a decrease in blood pressure, aimed at increasing cardiac output and/or constricting blood vessels to raise blood pressure in the immediate moment.
