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...

Which of the following statements is the most relevant phenomenon? Question 1 options: Increased preload due to vascular resistance High afterload because of backpressure against the left ventricle Impaired contractility due to aortic resistance Systolic impairment because of arterial stenosis Question 2 (2 points) Saved A nurse practitioner employe...

BSNC 6000 Module 1 Midterm Review Questions What are the effects of hypertension on macrocirculation? - Answer--Hypertension causes injury to the endothelial layer of the arteries which leads to plaque formation. Plaque restricts blood flow and can lead to ischemia. Plaque also weakens artery walls thereby increasing the risk of an aneurysm -Hypertension increases resistance to blood flow to the tissues. As a result, the heart pumps harder to overcome the resistance. A chronic increase in the...
