How does the heart function when a client is diagnosed with heart failure?

Question

Quizplus · Accepted Answer

When a client is diagnosed with heart failure, the contractility of the heart muscle decreases, meaning that it is less able to contract and pump blood effectively. This leads to a decrease in stroke volume, or the amount of blood ejected by the ventricle with each beat. Choice A is incorrect because heart failure typically leads to a decrease in blood volume, not an increase. Choice B is incorrect because the excessive blood is not being effectively pumped out. Choice C is also incorrect because the decrease in stroke volume occurs during the ejection phase, not the filling phase.
