ANS: B
HF is the inability of the heart to pump an adequate amount of blood to the systemic circulation at normal filling pressures to meet the body's metabolic demands. HF is not a disease but rather a result of the inability of the heart to pump efficiently. HF is not inherited. HF occurs most frequently secondary to congenital heart defects in which structural abnormalities result in increased volume load or increased pressures on the ventricles.
