A patient's preload is decreased. How should the nurse interpret this information? -the stroke volume has increased -the ventricles have stretched more -the muscarinic receptors are activated -the end-diastolic volume has decreased - the end-diastolic volume has decreased -cardiac preload can be expressed as either end-diastolic volume or en-diastolic pressure; thus, decreased preload is decreased end-diastolic volume or end-diastolic pressure. Which statement is correct regarding the di...

What is stroke volume? The volume that leaves the left ventricle per pump. Stroke volume is an important indicator of _______ SV is an important indicator of how *efficiently the heart can meet the body's demands* for adequate perfusion. When HR increases, Stroke volume (SV) ________ When heart rate increases, stroke volume tends to DECREASE due to the ventricles pumping faster than they can fill Vice versa: A decreased heart rate allows for the ventricles to fill up more le...
