You should: A. open and maintain her airway and assess breathing. B. assess for the presence of a medical identification tag. C. administer 100% oxygen via a nonrebreathing mask.

Because of their abnormal shape, red blood cells in patients with sickle cell disease are less apt to lodge in a blood vessel. C. Sickle cell disease is an inherited blood disorder that causes the blood to clot too quickly. D. The red blood cells of patients with sickle cell disease are round and contain hemoglobin.

Ketone production is the result of: A. rapid entry of glucose across the cell membrane. B. acidosis when blood glucose levels are low. C. fat metabolization when glucose is unavailable. D. blood glucose levels higher than 120 mg/dL.

Kussmaul respirations are an indication that the body is: A. trying to generate energy by breathing deeply B. attempting to eliminate acids from the blood C. compensating for decreased blood glucose levels D. severely hypoxic and is eliminating excess CO2
