Question

The health care provider has determined that a client diagnosed with cardiogenic shock will now require treatment with the intra-aortic balloon pump. The expected effect of the treatment is:

a) decreased afterload.
b) increased preload.
c) increased afterload.
d) decreased cardiac output.

Answer 1

Intra-aortic balloon pump treatment for cardiogenic shock reduces afterload, allowing the ventricles to pump blood more effectively against the vascular resistance.

Step-by-step explanation:

The expected effect of an intra-aortic balloon pump (IABP) treatment for a client diagnosed with cardiogenic shock is to decrease afterload. Cardiogenic shock is often caused by issues like myocardial infarction, arrhythmias, valve disorders, or cardiomyopathies, which impair the heart's ability to maintain cardiac output. Afterload is the resistance the ventricles must overcome to pump blood effectively. The IABP works by inflating and deflating a balloon in the aorta in synchrony with the cardiac cycle, which helps to increase blood flow during diastole and decrease resistance during systole, thereby reducing the afterload.
