A patient with a steadily increasing preload was experiencing a corresponding increase in stroke volume,but it has now begun to decrease.Which rationale would the nurse provide for this occurrence?
A)This fluctuation will occur until maximum preload has been reached.
B)The patient's heart rate is increasing,which causes a drop in stroke volume.
C)The patient's preload has reached a critical point and now stroke volume will decrease.
D)It is necessary to assess for a secondary pathophysiological event causing the stroke volume to decrease.
