Which factor(s) would decrease cardiac output?

Question

Quizplus · Accepted Answer

Decreased preload, meaning less blood returning to the heart, will result in a decrease in cardiac output. A decrease in venous return (choice A) would also result in a decrease in preload and therefore, cardiac output. Increased preload (choice C) would actually increase cardiac output, so it is not a factor that would decrease it. Vagal stimulation of the heart (choice B) would not have a significant impact on cardiac output.
