Which of these factors would cause a decrease in cardiac output?
A) increased body temperature
B) increased venous return
C) clinical depression
D) increased epinephrine secretion
E) decreased blood pH

Question

Quizplus · Accepted Answer

Clinical depression can cause a decrease in cardiac output due to a decrease in sympathetic nervous system activity, which leads to a decrease in heart rate and contractility. All of the other factors listed would cause an increase in cardiac output. Increased body temperature, increased venous return, and increased epinephrine secretion would all lead to an increase in heart rate and contractility, while decreased blood pH would cause vasodilation and an increase in cardiac output to compensate for decreased oxygen delivery to tissues.
