The nurse anticipates that if the stroke volume of a patient is reduced, the pulse will be:
stronger.
bradycardic.
irregular.
weaker.
The Correct Answer is D
A. A stronger pulse is typically associated with increased stroke volume or cardiac output.
B. Bradycardia is not directly related to a reduced stroke volume; pulse rate may not necessarily decrease.
C. An irregular pulse is more associated with arrhythmias or other cardiac conditions, not a reduction in stroke volume.
D. A weaker pulse is expected with a reduced stroke volume, as less blood is being pumped with each heartbeat, leading to a diminished pulse.
