While planning care for a heart patient,which principle should the nurse recall? Right ventricular afterload is affected by:
A) Vascular resistance in the systemic vessels
B) Right end-diastolic pressure
C) Pressures in the vena cava
D) Pulmonary vascular resistance

Question

Quizplus · Accepted Answer

Right ventricular afterload is affected by pulmonary vascular resistance because this is the pressure the ventricle must pump against.
Systemic resistance affects left-sided afterload.
Right end-diastolic pressure is a measurement of the pressure at diastole,but does not determine afterload.
Pressures in the vena cava do not affect right ventricle afterload directly.
