Afterload is most accurately described by which of the following?
Fluid volume status.
Atrial contraction (kick).
Resistance to blood flow.
Myocardial compliance.
The Correct Answer is C
Choice A reason: Fluid volume status affects preload, not afterload.
Choice B reason: Atrial contraction contributes to filling of the ventricles, not to afterload.
Choice C reason: Afterload is the resistance left ventricular must overcome to circulate blood, which is accurately described as resistance to blood flow.
Choice D reason: Myocardial compliance refers to the elasticity of the heart muscle, which affects how the heart fills, not the resistance it must overcome to eject blood.
