A client with systolic dysfunction has an ejection fraction of 38%. The nurse assesses for which physiologic change?
a. Increase in stroke volume
b. Decrease in tissue perfusion
c. Increase in oxygen saturation
d. Decrease in arterial vasoconstriction
B
In systolic dysfunction, the ventricle is unable to contract with enough force to eject blood effec-tively during systole. As the ejection fraction decreases (50% to 70% is normal), tissue perfusion decreases and the client develops activity intolerance. Stroke volume and oxygen saturation do not increase with a low ejection fraction.
