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 an injured patient of this age, you must recall that:-blood pressure is usually adequately maintained because the blood vessels of older people can contract easily.-his ability to physiologically compensate for his injury might be impaired due to an inability to increase cardiac output.-functional blood volume in patients of this age steadily increases due to increased production of red blood cells.-it is not uncommon to observe heart rates in excess of 150 beats/min in elderly patients with internal injuries.
