    Advertisements



    An adult's hemoglobin is 98% saturated with oxygen, but arterial oxygen content is decreased. The most likely cause of this condition is
    A) anemia
    B) an arteriovenous shunt
    C) hemoglobinopathy
    D) high-altitude hypoxia
    E) pulmonary diffusion defect

    If you have an arteriovenous shunt hemoglobin saturation is
    decreased.In anemia you have normal saturation but low arterial oxygen
    contentdue to low hemoglobin . . . my answer is A

    Hi,the correct answer is A...according to Goljan's notes, anemia has normal SaO2,normal PaO2, and low O2 content.
