You suspect that a 75-year-old man has internal injuries after he fell and struck his ribs and abdomen on the corner of a table. When assessing and treating him, it is important to recall that:
A. functional blood volume in patients of this age steadily increases due to increased production of red blood cells. B. blood pressure is usually adequately maintained because the blood vessels of older people can constrict easily.
