The nurse would expect which change in cardiac output for a patient with fluid volume overload?

A) Increased preload.
B) Decreased afterload.
C) Decreased tissue perfusion.
D) Increased heart rate.

Preload refers to the stretch of the ventricle related to the volume of blood;an increase in circulating volume would increase the preload of the heart.Afterload refers to resistance;increased pressure would lead to increased resistance,and afterload would increase.A decrease in tissue perfusion would be seen with hypovolemia.A decrease in fluid volume would cause an increase in heart rate as the body is attempting to increase cardiac output.
