Within a normal physiologic range, an increase in left ventricular end-diastolic volume would lead the nurse to monitor for:
a. an increased force of contraction.
b. a decrease in cardiac output.
c. an increase in heart rate.
d. heart failure.
ANS: A
An increase in end-diastolic volume leads to an increased force of contraction because fibers are stretched to handle increased volume. Cardiac output would increase. Although volume increas-es, heart rate does not respond accordingly. An increase in end-diastolic volume would not lead to heart failure since failure results in output decrease.
