when to suspect aortic atheroembolism
atherosclerosis, skin changes in legs (livedo reticularis or blue toe), elevated serum and urine eosinophils; (note cholesterol is part of the embolus -> cholesterol crystal embolization)
what to do in pt with hypovolemic hypoNa
give normal saline
when hypertonic saline is appropriate

2. start soft, low fat diet when pt’s appetite returns OR begin NG feeds at 72h
